Abstract
BackgroundCertolizumab pegol (CZP) has demonstrated clinical efficacy in patients with active non-radiographic axial spondyloarthritis (nr-axSpA) and objective signs of inflammation during the 52-week (wk) placebo (PBO)-controlled period and 104 wk open-label (OL) safety follow-up extension (SFE) of the C-axSpAnd study.1 There is, however, a paucity of data on the long-term efficacy of biologics in nr-axSpA according to patients’ baseline MRI and C-reactive protein (CRP) status.ObjectivesThis post hoc analysis from C-axSpAnd aimed to evaluate whether patients’ baseline MRI and CRP status impacted long-term (3-year) clinical responses to CZP.MethodsC-axSpAnd (NCT02552212) was a 3-year, phase 3, multicentre study. Adults (N=317) with nr-axSpA fulfilling the Assessment of SpondyloArthritis international Society (ASAS) classification criteria and objective signs of inflammation (CRP ≥ upper limit of normal (10 mg/L) [CRP+] and/or evidence of sacroiliitis on MRI [MRI+])2 were randomised 1:1 to PBO or CZP (400 mg at Wks 0, 2 and 4, then 200 mg every 2 wks [Q2W]) for 52 wks.3 Those enrolled into the SFE received OL CZP (200 mg Q2W) for an additional 104 wks.Ankylosing Spondylitis Disease Activity Score (ASDAS) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) alongside the percentage of patients achieving ASDAS major improvement (ASDAS-MI, C-axSpAnd primary outcome) and ASAS 40% response (ASAS40) at Wks 52 and 156 were assessed according to prespecified subgroups based on MRI/CRP status (MRI+/CRP+, MRI−/CRP+, MRI+/CRP−). All data are reported as observed case.Results243/317 (76.7%) patients entered the SFE, 120 from the group initially randomised to CZP (36 MRI+/CRP+, 32 MRI−/CRP+ and 52 MRI+/CRP−) and 123 from the initial PBO group (30 MRI+/CRP+, 34 MRI−/CRP+ and 59 MRI+/CRP−; 75/123 had switched to OL treatment in the 52 wk double-blind phase). 206/243 completed the SFE; 102/120 (85.0%) from the group initially randomised to CZP, 104/123 (84.6%) from the initial PBO group.Among CZP-randomised patients, mean ASDAS was similar between timepoints (MRI+/CRP+: 1.6 at Wk 52 vs 1.6 at Wk 156; MRI−/CRP+: 2.1 vs 2.2; MRI+/CRP−: 1.7 vs 1.6), the percentage achieving ASDAS-MI was lower at Wk 156 compared to Wk 52 across all subgroups (Figure 1 A). Patients initially randomised to PBO showed improvements in mean ASDAS over time (MRI+/CRP+: 2.1 Wk 52 vs 1.8 Wk 156; MRI−/CRP+: 2.2 vs 1.9; MRI+/CRP−: 2.0 vs 1.7) and a sustained proportion of patients achieved ASDAS-MI.Similar results were shown for BASDAI, with mean scores for CZP-randomised patients sustained from Wk 52 to Wk 156 across all subgroups (Figure 1 B). Mean BASDAI decreased (indicative of clinical improvements) from Wk 52 to Wk 156 in patients initially randomised to PBO, at which point the values aligned with those reported for the CZP-randomised group.In CZP-randomised patients, ASAS40 responses were sustained at Wk 156 compared to Wk 52. An increased percentage of patients achieved ASAS40 in all MRI/CRP subgroups initially randomised to PBO at Wk 156 compared to Wk 52 (Figure 1 C).ConclusionIn this analysis of patients with nr-axSpA and objective signs of inflammation, long-term clinical outcomes achieved after 1 year were generally sustained at 3 years across MRI+/CRP+, MRI−/CRP+ and MRI+/CRP− subgroups; ASDAS-MI was numerically highest in the MRI+/CRP+ subgroup.References[1]van der Heijde D.

Abstract
BackgroundIxekizumab (IXE) has demonstrated clinical efficacy in patients with active non-radiographic axial spondyloarthritis (nr-axSpA) together with significant repair of structural lesions in the sacroiliac joint (SIJ) on MRI. There is, however, a paucity of data as to which patients may be most responsive.ObjectivesWe aimed to evaluate whether patients’ gender, HLA-B27 status, and presence of MRI inflammation impacted the effect of treatment with IXE versus placebo (PBO) on MRI structural lesions in the SIJ in patients with nr-axSpA.MethodsPatients with active nr-axSpA, biologic-naïve (COAST-X, NCT02757352) were randomized 1:1:1 to ixekizumab 80 mg every 4 (Q4W) or 2 weeks (Q2W) or PBO. Structural lesions on SIJ MRI were assessed by the Spondyloarthritis Research Consortium of Canada (SPARCC) MRI SIJ structural score (SSS). Treatment comparisons used analysis of covariance based on observed cases. SPARCC SSS subgroup analyses were performed according to baseline gender, HLA-B27 status, and SPARCC MRI SIJ bone marrow oedema (BME) <4 and ≥4 subgroups, which reflects a definite MRI for inflammation in the SIJ typical of axSpA.ResultsOf 303 randomized patients, 266 patients (Q4W: n=85, Q2W: n=91, PBO: n=90) had an MRI scan at baseline and week 16. At baseline, SPARCC scores were consistently higher in males, and mostly higher in HLA-B27 and BME≥4 positive subgroups. Significant differences between patients treated with IXE versus PBO were observed for male patients, HLA-B27 positives, and those with baseline SPARCC BME ≥4. Numerically similar changes were observed in female patients, patients with negative HLA-B27, and patients with SPARCC BME<4, though not statistically significant.ConclusionEffects of IXE on structural repair are most evident in males, HLA-B27 positives, and patients with definite MRI inflammation at baseline.Table 1.MRI SIJ Structural Lesion Outcomes.LesionAnalysisPBOIXE Q4WIXE Q2WMale (n=39)Female (n=51)Male (n=44)Female (n=41)Male (n=43)Female (n=48)ErosionBL mean5·1671·9803·5452·8173·5232·594LS mean CFB (SE)0·51 (0·20)-0·11 (0·17)-0·63 (0·18)-0·11 (0·19)-0·51 (0·18)-0·32 (0·17)P value vs PBONANAp<0·001p>0·99p<0·001p=0·37FatBL mean2·0510·9122·0911·2931·4650·677LS mean CFB (SE)-0·02 (0·09)-0·03 (0·08)0·29 (0·08)0·03 (0·08)0·21 (0·08)0·04 (0·08)P value vs PBONANAp=0·01p=0·65p=0·062p=0·51BackfillBL mean1·1540·1670·6630·4150·7910·323LS mean CFB (SE)-0·20 (0·13)0·01 (0·11)0·39 (0·12)0·01 (0·12)0·34 (0·12)0·14 (0·11)P value vs PBONANAp<0·001p>0·99p=0·002p=0·38LesionAnalysisHLA-B27+HLA-B27-HLA-B27+HLA-B27-HLA-B27+HLA-B27-(n=64)(n=25)(n=61)(n=23)(n=65)(n=26)ErosionBL mean3·8202·1003·4672·5433·5151·827LS mean CFB (SE)0·27 (0·15)-0·10 (0·24)-0·49 (0·15)-0·01 (0·25)-0·50 (0·15)-0·17 (0·24)P value vs PBONANAp<0·001p=0·79p<0·001p=0·84FatBL mean1·5781·0201·3282·7831·2850·462LS mean CFB (SE)-0·06 (0·06)-0·06 (0·10)0·22 (0·06)0·01 (0·10)0·13 (0·06)0·10 (0·10)P value vs PBONANAp=0·002p=0·65p=0·027p=0·25BackfillBL mean0·7420·2400·5420·5650·7620LS mean CFB (SE)-0·12 (0·10)0·01 (0·16)0·28 (0·10)0 (0·17)0·27 (0·10)0·16 (0·16)P value vs PBONANAp=0·005p=0·96p=0·005p=0·52LesionAnalysisBME ≥4BME <4BME ≥4BME <4BME ≥4BME <4(n=40)(n=50)(n=27)(n=58)(n=38)(n=53)ErosionBL mean4·8632·1605·3522·1905·2761·425LS mean CFB (SE)0·42 (0·19)-0·06 (0·17)-0·70 (0·23)-0·23 (0·16)-0·71 (0·20)-0·19 (0·17)P value vs PBONANAp<0·001p=0·47p<0·001p=0·57FatBL mean0·7751·9101·9261·6031·6710·604LS mean CFB (SE)-0·02 (0·08)-0·02 (0·07)0·54 (0·10)-0·01 (0·07)0·28 (0·08)0·01 (0·07)P value vs PBONANAp<0·001p=0·90p=0·013p=0·74BackfillBL mean0·7500·4701·0190·3280·7630·387LS mean CFB (SE)-0·21 (0·12)0·01 (0·11)0·41 (0·15)0·11 (0·10)0·49 (0·13)0·05 (0·11)P value vs PBONANAp=0·002p=0·52p<0·001p=0·80CFB=change from BL.

Abstract
BackgroundRadiographs are not a sensitive or reliable imaging tool for detection of early sacroiliitis in juvenile spondyloarthritis (JSpA). However, radiographs are still commonly performed in some areas due to difficulty in accessing MRI. As such, radiographs were included in the imaging data considered for an axial disease classification criteria development study, but only when there was no suitable MRI available.ObjectivesWe aimed to define criteria for unequivocal evidence of sacroiliitis on pelvic radiography in skeletally immature children and adolescents for use in classification criteria.MethodsSubjects were a cohort of JSpA patients with suspected axial disease. All subjects had symptom onset prior to age 18 years and underwent MRI as part of a diagnostic evaluation for axial disease; a subset of subjects also had a dedicated pelvic radiograph. Using a web-based interface, 6 musculoskeletal imaging experts, blinded to clinical details, reviewed the radiographs and graded them according to the modified New York (mNY) criteria. A two-way random effects intraclass correlation coefficient (ICC) was used to assess agreement. Next, the central imaging team underwent an iterative consensus process to define unequivocal evidence of sacroiliitis on pelvic radiography in skeletally immature children. Radiographs with at least two raters assigning a non-zero mNY grade were re-reviewed for the presence/absence of “unequivocal evidence of sacroiliitis” according to the consensus definition. Agreement was assessed with Fleiss’s kappa statistic with agreement interpreted as poor ≤0.40, fair 0.41-0.59, good 0.60-0.74, and ≥0.75 excellent. Sensitivity, specificity, and positive and negative predictive values (PPV, NPV) were calculated to assess performance of the novel definition using structural lesion typical of juvenile axial disease on MRI as the reference standard (erosion in ≥3 sacroiliac joint (SIJ) quadrants or at least one of the following lesions in ≥2 SIJ quadrants: sclerosis, fat lesion, backfill, ankylosis).ResultsRadiographs from 120 subjects, 61% male, median age 14.7 years (range 6.7-20.1 years), had an AP dedicated pelvic radiograph available for scoring. The ICC for mNY grade amongst 6 central raters was fair for joints with at least one rater reporting a non-zero grade (0.45, 95% CI: 0.34-0.57). After multiple iterations and discussion, the consensus definition of unequivocal sacroiliitis by radiograph in skeletally immature children and adolescents was deemed “Unequivocal lesion (erosion, sclerosis, or ankylosis [partial or complete]) that must include at least one iliac bone. When sclerosis is present in isolation, if measurable, should extend ≥5mm from the joint surface. The decision may be influenced by the presence of other lesions, which in themselves do not suffice to meet the criterion.” Sixteen radiographs were assessed using the consensus definition. 8 (50%) were rated as unequivocal sacroiliitis and Fleiss’ kappa statistic was good at 0.61 (95% CI: 0.41-0.80). Across raters, the sensitivity, specificity, PPV and NPV of the consensus definition on radiograph using structural lesions typical of sacroiliitis on MRI as the reference standard were 80% (95%CI: 44.4-97.5), 100% (95% CI: 54.1-100), 100% (63.1-100) and 75% (95% CI:34.9-96.8), respectively.ConclusionWe propose a consensus-derived definition of unequivocal sacroiliitis by radiography in skeletally immature children and adolescents with good expert rater agreement. Additionally, the consensus-definition had moderate to high sensitivity and PPV and high specificity and NPV with typical structural lesions on MRI as the reference standard. This definition has applicability to JSpA axial disease classification criteria when MRI is unavailable.Figure 1.Examples of radiographs with unequivocal evidence of sacroiliitis in skeletally immature children as indicated by definite erosions of both iliac bones (A and B) and definite iliac sclerosis (A).Disclosure of InterestsPamela F.

Abstract
BackgroundIn 2009, ASAS published a ‘Definition of active sacroiliitis on MRI for classification of axial spondyloarthritis (axSpA)’. This definition relied on two MRI sequences to make this determination – semicoronal T1 and STIR. Since then, this approach has frequently been used for diagnosis, even though that was never the intent of the definition. In 2015, the European Society of Skeletal Radiology (ESSR) published its recommendations for an SIJ MRI image acquisition protocol (IAP) for diagnostic purposes that required 4 MRI sequences but there is still no IAP that has been widely accepted as a minimum standard worldwide. In 2020, an informal survey of 24 academic sites (12 Europe, 12 North America) confirmed that 24/24 sites performed a minimum of 3 MRI sequences for diagnosis (19 performed 4-8 sequences) because the 2-sequence protocol was considered inadequate.ObjectivesTo develop the minimum requirements for a standardized IAP for MRI of the sacroiliac joints for diagnostic ascertainment of sacroiliitis.MethodsAll radiologist members of the ASAS and SPARTAN Classification in axSpA (CLASSIC) project, along with one European and one North American rheumatologist with extensive MRI experience in SpA clinical practice and research, were invited to participate in a consensus exercise. A draft IAP was circulated to all participants along with background information and justification for the draft proposal. Feedback on all issues was received by email, tabulated and recirculated. Participants were broadly in favour of the proposal and two months later a teleconference meeting took place and remaining points of contention were resolved. Examples of the proposed IAP performed on new, 10 and 22 years’ old MRI scanners were made available for review in DICOM format. Next the revised draft of the IAP was presented at the ASAS annual meeting to the entire membership on 14 January 2022, and voted on.ResultsA 4-sequence IAP, 3-semicoronal and 1-semiaxial, is recommended for diagnostic ascertainment of sacroiliitis and its differential diagnoses (Table 1). It must meet the following requirements: Semicoronal sequences should be parallel to the dorsal cortex of the S2 vertebral body, and include: 1) a sequence sensitive for the detection of active inflammation being T2-weighted with suppression of fat signal; 2) a sequence sensitive for the detection of structural damage in bone and bone marrow with T1-weighting; 3) a sequence that is designed to optimally depict the bone-cartilage interface of the articular surface and be sensitive for detection of bone erosion; plus 4) a semiaxial sequence sensitive for inflammation detection. The IAP was approved at the ASAS annual meeting by a vote of the entire membership with 91% in favour.Table 1.A standardized SIJ MRI Acquisition Protocol for diagnostic ascertainment of sacroiliitisOrientationSequenceTarget Lesion(s)Semicoronal Parallel to the dorsal cortex of the S2 vertebral bodyT1-weighted Spin EchoStructural: Fat lesions, erosion, sclerosis, backfill, ankylosis.T2-weighted with suppressed fat signal (STIR, T2FS or equivalent)Inflammatory: Bone marrow edema (BME)T1-weighted with suppressed fat signal (2D or 3D T1FS)Structural: Erosion of the articular surfaceSemiaxial Perpendicular to semicoronalT2-weighted with suppressed fat signal (STIR, T2FS or equivalent)Inflammatory: Bone marrow edema (BME)ConclusionA standardized IAP for MRI of the sacroiliac joints for diagnostic ascertainment of sacroiliitis is recommended and should be comprised of a minimum of 4 sequences, in 2-planes, that will optimally visualize inflammation, structural damage, and the bone-cartilage interface.Disclosure of InterestsRobert Lambert Paid instructor for: Novartis, Consultant of: Calyx, CARE Arthritis, Image Analysis Group, Xenofon Baraliakos Speakers bureau: Abbvie, Pfizer, MSD, UCB, Novartis, Lilly, Galapagos, Hexal, Paid instructor for: Abbvie, Pfizer, MSD, UCB, Novartis, Lilly, Galapagos, Hexal, Consultant of: Abbvie, Pfizer, MSD, UCB, Novartis, Lilly, Galapagos, Hexal, Grant/research support from: Abbvie, MSD, Novartis, Lilly, Stephanie Bernard Consultant of: Elsevier Amirsys, John Carrino Consultant of: Pfizer, Regeneron, Globus, Carestream, Image Analysis Group, Image Biopsy Lab, Torsten Diekhoff Speakers bureau: Novartis, MSD, Canon MS, Consultant of: Eli Lilly, Iris Eshed: None declared, Kay-Geert Hermann Speakers bureau: AbbVie, Pfizer, MSD, Novartis.

Abstract
BackgroundBimekizumab (BKZ) is a monoclonal IgG1 antibody that selectively inhibits IL-17F in addition to IL-17A. BKZ has shown rapid and sustained efficacy and was well tolerated up to 156 weeks (wks) in a phase 2b study in patients (pts) with active ankylosing spondylitis.1,2ObjectivesTo assess efficacy and safety of BKZ vs placebo (PBO) in pts with active non-radiographic axial spondyloarthritis (nr-axSpA) up to Wk 24 in the ongoing pivotal phase 3 study, BE MOBILE 1.MethodsBE MOBILE 1 (NCT03928704) comprises a 16-wk double-blind, PBO-controlled period and 36-wk maintenance period. Pts were aged ≥18 yrs, had BASDAI ≥4 and spinal pain ≥4 at BL, and sacroiliitis on MRI and/or elevated CRP at screening. Pts were randomised 1:1, BKZ 160 mg Q4W:PBO. From Wk 16, all pts received BKZ 160 mg Q4W. Primary and secondary efficacy endpoints were assessed at Wk 16.ResultsOf 254 randomised pts (BKZ: 128; PBO: 126), 244 (96.1%) completed Wk 16, 240 (94.5%) Wk 24. BL characteristics were comparable between groups: mean age 39.4 yrs, symptom duration 9.0 yrs; 54.3% pts male, 77.6% HLA-B27+, 10.6% TNFi-experienced. At Wk 16, the primary (ASAS40: 47.7% BKZ vs 21.4% PBO; p<0.001) and all ranked secondary endpoints were met (Table 1).

Abstract
BackgroundRheumatologists recommend vaccination in rheumatoid arthritis (RA) and axial spondyloarthritis (axSpA) patients, but there are few studies on the occurrence of adverse events (AEs), particularly worsening disease related activity and unrelated immune reactions in these groups.ObjectivesTo evaluate the uptake of COVID vaccination in RA and axSpA patients, compare the frequency of AEs, and identify risk factors associated with vaccine AEs in two prospective cohorts comprised of these patients.MethodsThe IMPACT study is a monthly survey of two prospective cohorts of established RA and axSpA patients in northern Alberta, Canada from November 2020-2021 who answered at least one or more Redcap surveys through de-identified email link surveying demographics, disease characteristics, COVID symptoms, treatment of RA and axSpA, health care utilization, vaccination status, vaccine AEs and use of cannabis. Univariate analyses evaluated independent variables associated with the dependent variables of (1) any AE, (2) any severe AE, (3) any arthritis flare, and (4) any severe arthritis flare, followed by multivariate analyses of these four dependant variables using all clinically relevant variables from the univariate analysis.Results773/2167 patients (RA 574, axSpA 197) responded to at least one survey. 32/663 (5%) were single vaccinated, 631 (95%) double vaccinated and 230 (54%) triple vaccinated with 80% receiving Pfizer, 24% Moderna, 28% AstraZeneca and 30% “other”. 456 (69%) reported at least one AE (Figure 1) with 21 (3%) patients seeing a physician for their AE. Increased age was associated with all AEs. RA patients had lower reported AEs versus axSpA patients for all AE definitions except for severe arthritis flares. Generally, males reported worse AEs (Table 1). “Any arthritis flare” was lower in patients reporting cannabis use.Table 1.Summary of Multivariate Level Mixed-Effect Logistic Regression Models Evaluating the IMPACT of RA and axSpA Disease Characteristics on Vaccine AEsVariableAny Adverse EventOR (95 % CI) p valueSevere Adverse Event* OR 95 % CI) p valueAny Arthritis Flare or Joint Ache Adverse Event OR (95 % CI) p valueAny Severe Arthritis Flare or Joint Ache* OR (95 % CI) p valueGenderMale1.47 (0.89 – 2.43)p=0.132.10 (1.30-3.41)p=0.0032.05 (1.20 – 3.50) p=0.013.97 (1.84 – 8.57)p=0.0004FemaleAge1.06 (1.04 – 1.08)p<0.011.05 (1.03 – 1.06)p<0.011.03 (1.01 – 1.04)p=0.0031.03 (1.01 – 1.06)p=0.004Rheumatic Disease TypeRA0.42 (0.23 – 0.76)p=0.050.55 (0.31 – 0.98)p=0.040.52 (0.28 – 0.98)p=0.040.78 (0.34 – 1.78)p=0.55axSpASteroidsYes0.85 (0.40 – 1.83) P=0.680.66 (0.32 – 1.35) p=0.250.84 (0.36 – 1.95) p=0.690.38 (0.15 – 0.97)p=0.04NoNSAIDSYes1.11 (0.81 – 1.52) p=0.511.03 (0.75 – 1.41)p=0.861.05 (0.74 – 1.48)p=0.801.17 (0.73 – 1.89)p=0.52NoCurrent Disease Activity0.95 (0.88 – 1.03) p=0.230.90 (0.83 – 0.97)p=0.190.92 (0.85 – 1.00)p=0.060.82 (0.74 – 0.92)p=0.001HAQ1.08 (0.73 – 1.61) p=0.700.77 (0.52 – 1.14)p=0.010.74 (0.48 – 1.13)p=0.170.65 (0.38 – 1.11)p=0.12Nicotine productsYes1.33 (0.75 – 2.37) p=0.341.42 (0.80 – 2.52)p=0.241.15 (0.60 – 2.01)p=0.760.97 (0.43 – 2.17)p=0.94NoCannabis productsYes0.78 (0.49 – 1.25) p=0.300.87 (0.55 – 1.38)p=0.550.51 (0.31 – 0.83)p=0.070.66 (0.35 – 1.26)p=0.21NoDMARDsYes1.98 (1.28 – 3.06)p=0.0021.52 (1.01 – 2.28)p=0.051.43 (0.91 – 2.23) p=0.121.86 (1.03 – 3.36)p=0.04NoBiologic DMARDYes0.72 (0.42 – 1.25) p=0.240.79 (0.45 – 1.41) p=0.431.20 (0.66 – 2.18 p=0.541.39 (0.63 – 3.08)p=0.42No*Severe = Any of the following: ranked moderate to severe and/or lasting more than 7 days and/or saw physicianConclusionRA and axSpA patients showed high uptake of COVID vaccination with largely minor AEs.

Abstract
BackgroundThere are limited data as to the frequency of spinal lesions on MRI in patients without MRI or radiographic features typical of sacroiliac joint (SIJ) disease and to what degree spine MRI might enhance diagnostic evaluation.ObjectivesTo assess the frequency of MRI lesions of the spine in the ASAS-Classification Cohort according to the presence of MRI SIJ lesions typical of axSpA and/or radiographic sacroiliitis (mNY+).MethodsMRI spine lesions were recorded by 9 central readers in an eCRF that captures global assessment of the spine (“Is the MRI consistent with axSpA: yes/no”) (yes=MRIglobal spine+) and detailed anatomical-based scoring of each discovertebral unit plus lateral and posterior structures. Independently, readers globally assessed SIJ scans for active and/or structural lesions typical of axSpA. We compared the frequency of MRIglobal spine+ and frequencies of different types of spinal lesions according to the presence/absence of axSpA on global evaluation of SIJ scans by ≥5 of 9 readers (MRIglobal SIJ+) and mNY+ sacroiliitis using Fisher’s exact test. Analysis was also stratified by rheumatologist diagnosis.ResultsAmong 51 cases with SIJ as well as spine MRI scans and radiographs of the SIJ,19 (37.3%) had MRIglobal SIJ+, and 12 (23.5%) and 7 (13.7%) had MRIglobal spine+ by ≥2 and ≥5 reader agreement, respectively. MRIglobal spine+ occurred significantly more frequently in the presence of mNY+ sacroiliitis and MRIglobal SIJ+ but was also recorded in 4 of 32(12.5%) (≥2 readers) and 1 of 32(3.4%) (≥5 readers) cases that were MRIglobal SIJ- and x-ray negative, all 4 cases being diagnosed with axSpA. Moreover, vertebral corner BME lesions, but not spinal structural lesions, were significantly more frequent in MRIglobal SIJ- cases that had been clinically diagnosed as axSpA versus non-axSpA (Table 1).Table 1.Frequency of Spinal MRI lesions According to SIJ Imaging Positive for AxSpAMRI Spinal Lesions, N (%)MRIglobalSIJ+ (n=19)MRIglobalSIJ- (n=32)P valueMRIglobal SIJ+ and/or mNY+ (n=22)MRIglobal SIJ- and mNY- (n=29)P valueMRIglobal SIJ- and SpA Diagnosis+(n=17)MRIglobal SIJ- and SpA Diagnosis- (n=15)P valueMRIglobal consistent with axSpA (≥2/9 readers agree)8 (42.1%)4 (12.5%)0.048(36.4%)4(13.8%)0.104 (23.5%)0 (0%)0.10MRIglobal consistent with axSpA (≥5/9 readers agree)6 (31.6%)1 (3.1%)0.016 (27.3%)1 (3.4%)0.031 (5.9%)0 (0%)1.0VC BME ≥19 (47.4%)15 (46.9%)46.9% RT 62.5% CT 29.4% GT1.010(45.5%)14(48.3%)1.011 (64.7%)4 (26.7%)0.04VC BME ≥26 (31.6%)10 (31.3%)31.2% RT 55.6% CT 19.6% GT1.06(27.3%)10(34.5%)0.769 (52.9%)1 (6.7%)0.007VC BME ≥36 (31.6%)7 (21.9%)21.9% RT 53.8% CT 13.7% GT0.526(27.3%)7(24.1%)1.07 (41.2%)0 (0%)0.008VC BME ≥45 (26.3%)5 (15.6%)0.475(22.7%)5(17.2%)0.735 (29.4%)0 (0%)0.046Vertebral Endplate BME ≥12 (10.5%)3 (9.4%)1.02(9.1%)3(10.3%)1.02 (11.8%)1 (6.7%)1.0Lateral vertebral BME3 (15.8%)3 (9.4%)0.663(13.6%)3(10.3%)1.03 (17.6%)0 (0%)0.23Facet BME ≥14 (21.1%)1 (3.1%)3.1% RT 20.0% CT 2.0% GT0.064(18.2%)1(3.4%)0.151 (5.9%)0 (0%)1.0Posterior BME ≥15 (26.3%)2 (6.3%)0.095(22.7%)2(6.9%)0.221 (5.9%)1 (6.7%)1.0VC Fat ≥18 (42.1%)42.1% RT 44.4% CT 15.7% GT10 (31.3%)31.2% RT 55.6% CT 19.6% GT0.558(36.4%)10(34.5%)1.05 (29.4%)5 (33.3%)1.0VC Fat ≥27 (36.8%)5 (15.6%)0.107(31.8%)5(17.2%)0.323 (17.6%)2 (13.3%)1.0VC Fat ≥36 (31.6%)31.6% RT 66.7% CT 11.8% GT3 (9.4%)0.066(27.3%)3(10.3%)0.151 (5.9%)2 (13.3%)0.59VC Fat ≥46 (31.6%)1 (3.1%)0.016(27.3%)1(3.4%)0.030 (0%)1 (6.7%)0.47Lateral Fat ≥16 (31.6%)2 (6.3%)0.046(27.3%)2(6.9%)0.060 (0%)2 (13.3%)0.21Erosion ≥13 (15.8%)2 (6.3%)0.353(13.6%)2(6.9%)0.641 (5.9%)1 (6.7%)1.0Bone Spur ≥14 (21.1%)5 (15.6%)0.714(18.2%)5(17.2%)1.04 (23.5%)1 (6.7%)0.34Ankylosis ≥12 (10.5%)0 (0%)0.132(9.1%)0(0%)0.180 (0%)0 (0%)-ConclusionSpinal lesions on MRI indicative of axSpA per majority read occurred in about 3% of patients without positive imaging in the SIJ.

Abstract
BackgroundThroughout the pandemic, there has been ongoing concern that people with autoimmune diseases such as rheumatoid arthritis (RA) and axial spondyloarthritis (axSpA) will have more severe COVID-19 disease due to immune dysfunction associated with autoimmune diseases and their treatment.ObjectivesWe aimed to compare the severity of COVID-19 in patients with RA versus axSpA and characterize the predictors of COVID-19 severity during the pre-Omicron pandemic phases.MethodsThe IMPACT (IMPact of inflammatory Arthritis on COVID Outcomes STudy) study is a monthly survey of two established northern Alberta, Canada prospective cohorts of RA and axSpA patients from November 2020-2021 who answered Redcap surveys through de-identified email link surveying patient demographics, disease characteristics, COVID-19 symptoms, treatment of RA and axSpA, health care utilization, vaccination status and vaccine adverse events. Descriptive and univariate analyses (dependent variable = severe COVID-19) were performed followed by multivariate analyses of all significant and clinically relevant independent variables from the univariate analysis. Infection severity was defined as any patient with COVID-19 symptoms who visited a doctor, ER or required hospital admission.Results773 of 2167 (36%) patients (RA n=574, axSpA n=197) registered in both cohorts answered at least one baseline survey, 28 (4%) reporting positive COVID-19 tests (24 positive once). Of 442 reporting COVID-19 symptoms during the survey, 11 (3%) were admitted for a mean of 4 days, 2 requiring ICU or blood clot treatment and 1 requiring advanced therapy. 116 (26%) visited a physician for Covid symptoms. Univariate analysis showed that the use of steroids, NSAIDs and increased disease activity were associated with having less severe infection but these associations were not significant in the multivariate analysis (Table 1). There were no significant impacts of RA vs axSpA, age, gender, treatment, disease activity, or smoking.Table 1.Multivariate Level Mixed-Effect Logistic Regression Model: IMPACT of RA and axSpA Disease Characteristics on COVID Infection Severity Defined as Patients with COVID Symptoms Requiring Visit to Doctor, Emergency Room and/or Hospital Admission.VariableCoefficient (S.E)Odds Ratio (95 % Confidence Interval)P-valueGenderMale0.17 (0.34)1.18 (0.61 – 2.31)0.6193FemaleReferenceAge-0.01 (0.01)0.99 (0.97 – 1.01)0.2543Rheumatic Disease TypeRA0.18 (0.40)1.20 (0.58 – 2.48)0.6213SpAReferenceSteroidsYes-0.40 (0.56)0.67 (0.23 – 2.01)0.4757NoReferenceNSAIDSYes-0.20 (0.26)0.82 (0.49 – 1.37)0.4508NoReferenceCurrent Disease Activity-0.04 (0.06)0.96 (0.85 – 1.09)0.5275HAQ-0.03 (0.29)0.97 (0.55 – 1.70)0.9041Nicotine productsYes-0.67 (0.37)0.51 (0.25 – 1.06)0.0714NoReferenceCannabis productsYes-0.45 (0.31)0.64 (0.35 – 1.18)0.1510NoReferenceDMARDsYes0.26 (0.30)1.30 (0.72 – 2.35)0.3860NoReferenceBiologic DMARDYes-0.46 (0.43)0.63 (0.27 – 1.46)0.2813NoReferenceConclusionPossible disease related risk factors for increased COVID-19 severity in RA and axSpA patients preceding the onset of the Omicron variant including use of steroids or DMARDs were not associated with severe infection.

Abstract
BackgroundFor classification in juvenile spondyloarthritis (JSpA), it is important to develop cut-offs for active and structural lesions typical of axial disease on MRI that are readily and consistently interpreted. Since the maturing sacroiliac joint (SIJ) looks different from the adult SIJ, the criteria developed for positive MRI in adults may not be applicable in JSpA.ObjectivesAs part of a study developing classification criteria for axial disease in JSpA, we aimed to determine quantitative SIJ imaging lesion cut-offs for inflammatory and structural lesions typical of axial JSpA using majority imaging expert decision as the reference criterion.MethodsSubjects were a retrospective cohort of children with SpA who met the provisional Pediatric Rheumatology International Trials Organization criteria for enthesitis/spondylitis-related juvenile idiopathic arthritis or had a rheumatologist JSpA diagnosis. All subjects had symptom onset prior to age 18 years and underwent MRI as part of a diagnostic evaluation for axial disease. To enable SIJ quadrant-based scoring, all MRIs included semi-coronal slices through the cartilaginous part of the joint on fluid sensitive sequences and on T1-weighted sequences for the assessment of inflammation and structural lesions, respectively. MRIs were reviewed by 6 musculoskeletal imaging experts who were blinded to clinical details. MRI evaluation of the SIJ was based on standardized lesion definitions that were decided by consensus of the central imaging team and represented a mix of definitions from ASAS and the Juvenile Arthritis MRI Score Outcome Measures in Rheumatology working group. Using a web-based interface, raters globally assessed the presence or absence of lesions typical of axial SpA and performed SIJ quadrant or joint based scoring. Lesion scores were generated by averaging the scores of all raters. Sensitivity and specificity of lesion cut-offs were calculated using rater majority (≥4/6 raters) on a global assessment of the presence/absence of active or structural lesions typical of axial SpA with high confidence (confidence of ±3 or stronger on confidence scale from -5, “Definitely No”, to +5, “Definitely Yes”) as the reference standard.ResultsImaging from 243 subjects, 61% male, median age 14.9 years, had sequences available for detailed MRI scoring. Active inflammatory lesion typical of axial disease in JSpA was defined as bone marrow edema (BME) in at least 3 SIJ quadrants (sensitivity 98.6%, specificity 96.5%). For structural lesion typical of axial JSpA, the optimal cut-off was erosion in at least 3 quadrants or at least one of the following lesions in at least 2 SIJ quadrants: sclerosis, fat lesion, backfill, ankylosis (sensitivity 98.6%, specificity 95.5%).ConclusionWe propose data-driven cut-offs for active inflammatory and structural lesions on MRI typical of axial disease in JSpA that have high specificity and sensitivity using central imaging global assessment as the reference standard.Table 1.Performance of cut-offs for inflammatory and structural lesions of axial diseaseCut-offs for number of SIJ quadrants (any location)Sensitivity (95% CI)Specificity (95% CI)Definite active lesionBME score ≥2100 (95.0-100)93.5 (88.7-96.7)BME score ≥398.6 (92.5-100)96.5 (92.5-98.7)BME, same location on ≥3 consecutive slices88.6 (78.7-94.9)98.8 (95.8-99.9)Definite structural lesionErosion ≥295.7 (88-99.1)96.8 (92.7-99)Erosion, same location on ≥2 consecutive slices94.3 (86-98.4)98.1 (94.5-99.6)Erosion ≥391.4 (82.3-96.8)98.7 (95.4-99.8)Sclerosis ≥262.9 (50.5-74.1)98.1 (94.5-99.6)Fat lesion ≥222.9 (13.7-34.4%)98.7 (95.4-99.8%)Backfill ≥220 (11.4-31.3)100 (97.7-100)Ankylosis ≥21.3 (0.2-4.7)100 (94.9-100)ANY of the following in ≥2 SIJ quadrants: erosion, sclerosis, fat lesion, backfill, ankylosis98.6 (92.3-100)93.6 (88.5-96.9)Erosion ≥3 quadrants OR ≥2 quadrants of at least one of the following lesions: sclerosis, fat, backfill, ankylosis98.6 (92.3-100.0)95.5 (91.0-98.2)Disclosure of InterestsPamela F.

Abstract
BackgroundThe web-based Spondyloarthritis Research Consortium of Canada (SPARCC) real-time iterative calibration (RETIC) modules for scoring MRI lesions in axial spondyloarthritis (axSpA) have been created by SPARCC developers to enable remote training of readers to appropriately use the SPARCC MRI inflammation and structural damage instruments and to attain adequate scoring proficiency.ObjectivesWe aimed to test the performance of these modules in enhancing scoring proficiency in comparison to SPARCC developers.MethodsThe SPARCCRETIC SIJ inflammation and structural damage modules are each comprised of 50 DICOM axSpA cases with baseline and follow up scans and an online scoring interface based on SIJ quadrants. Continuous visual real-time feedback regarding concordance/discordance of scoring per SIJ quadrant with expert readers is provided by a color-coding scheme. Reliability is assessed in real-time by intra-class correlation coefficient (ICC), ICC data being provided every 10 cases, which are scored until proficiency targets for ICC are attained. In the present exercise, participants (n=15) from the EuroSpA Imaging project were randomized, stratified by reader expertise in scoring with SPARCC, to one of two reader training strategies (groups A and B) that each comprised 3 stages (25 patients per stage, 2 timepoints, blinded to chronology; independent assessment of Inflammatory and structural lesions): Group A. 1. Review of original SPARCC manuscript describing scoring method. 2. Review of PowerPoint summary of SPARCC method plus completion of SPARCCRETIC module. 3. Re-review of PowerPoint summary. Group B. Same 3-step strategy as A except SPARCCRETIC module completed at stage 3. The reliability of scoring was compared to an expert radiologist (SPARCC developer).ResultsVery good scoring proficiency for status and change scores was evident for SPARCC BME even by non-experienced readers with similar levels of reliability irrespective of prior expertise. The beneficial impact of the SPARCCRETIC module on scoring proficiency was most consistently evident for the scoring of structural lesions and for Strategy B, where the impact was evident for all structural lesions, level of reader expertise, and status as well as change scores (Table 1). Scoring proficiency improved the most for the least experienced readers (Figure 1).Table 1.Inter-rater reliability (Status/Change ICC) compared to radiologist SPARCC developerMRI LesionReader expertiseStrategy AStrategy BStage 1 cases (n=25)Stage 2 cases (n=25)Stage 3 cases (n=25)Stage 1 cases (n=25)Stage 2 cases (n=25)Stage 3 cases (n=25)BMENone (n=4)0.91 / 0.940.83/0.820.77/0.780.82/0.880.65/0.820.88/0.90Intermediate (n=6)0.88/0.880.90/0.900.85/0.900.93/0.940.78/0.800.83/0.80Experienced (n=5)0.92/0.940.90/0.880.92/0.930.83/0.880.84/0.900.89/0.89ANKYLOSISNone (n=4)0.86/0.660.83/0.280.86/0.780.66/0.410.69/0.340.88/0.80Intermediate (n=6)0.89/0.570.83/0.370.92/0.810.82/0.680.74/0.470.93/0.84Experienced (n=5)0.96/0.760.93/0.640.94/0.860.97/0.240.83/0.410.91/0.79BACKFILLNone (n=4)-0.08/-0.050.38/0.220.59/0.380.64/0.130.05/-0.090.47/0.27Intermediate (n=6)0.41/0.130.44/0.420.69/0.390.50/0.220.30/0.300.70/0.42Experienced (n=5)0.82/0.380.55/0.400.91/0.640.65/0.240.21/0.260.71/0.30EROSIONNone (n=4)0.13/-0.080.67/0.420.51/0.330.34/0.330.23/0.080.38/0.37Intermediate (n=6)0.42/0.180.56/0.120.51/0.440.33/0.270.45/0.180.53/0.39Experienced (n=5)0.61/0.330.64/0.340.64/0.420.51/0.270.58/0.110.62/0.31FAT METAPLASIANone (n=4)0.62/0.540.30/0.170.57/0.290.43/0.530.38/0.070.83/0.63Intermediate (n=6)0.49/0.380.59/0.300.79/0.510.57/0.780.50/0.420.81/0.47Experienced (n=5)0.75/0.620.81/0.340.91/0.700.84/0.900.56/0.130.78/0.37ConclusionAttaining scoring proficiency for MRI structural lesions in axSpA is difficult but can be consistently improved by using the SPARCCRETIC module, even for experienced readers.Figure 1.Disclosure of InterestsWalter P Maksymowych Speakers bureau: Abbvie, Janssen, Novartis, Pfizer, UCB, Consultant of: Abbvie, Boehringer Ingelheim, Celgene, Eli-Lilly, Galapagos, Novartis, Pfizer, UCB, Grant/research support from: Abbvie, Novartis, Pfizer, UCB, Anna Enevold Fløistrup Hadsbjerg Grant/research support from: Novartis, Mikkel Østergaard Consultant of: AbbVie, BMS, Boehringer-Ingelheim, Celgene, Eli Lilly and Company, Galapagos, Gilead, Hospira, Janssen, Merck, Novartis, Novo, Orion, Pfizer, Regeneron, Roche, Sandoz, Sanofi, UCB, Grant/research support from: AbbVie, BMS, Merck, Celgene, Novartis, Raphael Micheroli: None declared, Susanne Juhl Pedersen Grant/research support from: Novartis, Adrian Ciurea: None declared, Nora Vladimirova Grant/research support from: Novartis, Michael J Nissen Speakers bureau: Eli-Lilly, Janssen, Novartis, Consultant of: Abbvie, Celgene, Eli-Lilly, Janssen, Novartis, Pfizer, Kristyna Bubova: None declared, Stephanie Wichuk: None declared, Manouk de Hooge: None declared, Ashish Jacob Mathew Grant/research support from: Novartis, Karlo Pintaric: None declared, Monika Gregová: None declared, Ziga Snoj: None declared, Marie Wetterslev: None declared, Karel Gorican: None declared, Joel Paschke: None declared, Iris Eshed: None declared, Robert G Lambert Paid instructor for: Novartis

Abstract
BackgroundClinicians face uncertainties in their daily practice when requesting imaging examinations for patients with suspected axial spondyloarthritis (axSpA) or when producing an imaging report because the requirements and desired information of radiologists and rheumatologists / orthopedics alike are sometimes not completely known or understood.ObjectivesThis project aimed to develop practical consensus recommendations for the standardized communication around imaging of sacroiliac joints and spine for diagnostic purposes in patients with suspected axSpA or their management in clinical practice.MethodsAn international task force was established combining radiologists (n=7) and rheumatologists (n=13) from the Assessment of SpondyloArthritis international Society (ASAS), two members of Young ASAS and a patient representative. The task force defined the project’s aims and developed a project statement. Then, considering published literature and the work of other groups, two survey rounds were designed, and all ASAS members invited to respond: first, to identify items for further consideration, second, to consider the detail of information to be communicated. Finally, ASAS members discussed the recommendations proposed by the task force during the ASAS annual workshop in January 2022 and voted regarding endorsement of the recommendations.ResultsThe final set of recommendations is presented in Figure 1. Six recommendations deal with imaging requests in patients with axSpA. The first three recommendations entail clinical features, patients’ symptoms and risk factors. Recommendation 4 concerns previous imaging and reports and recommendation 5 refers to contraindications to imaging or contrast media. Recommendation 6 is about the suspected diagnosis and possible clinical differential diagnoses and the reason for the examination. Eleven additional recommendations refer to the radiology report. The first point addresses clinical information included in the report. Recommendations 2 to 4 advise on information about the technical conduct of the exam, the use of contrast media and image quality. Imaging findings that should be mentioned in the report if present are listed in recommendations 5 to 7. Finally, recommendations 8 to 11 combine advice for the conclusion, and for suggesting additional imaging or referral to a rheumatology expert if a different physician requested the imaging. The recommendations were endorsed by ASAS with approval from 73% of voting members (43 agreed, 10 rejected, 6 abstained).Figure 1.ASAS recommendations for requesting and reporting imaging in patients with suspected axial Spondyloarthritis.ConclusionThese ASAS recommendations provide guidance for requesting and reporting imaging examinations in the context of axSpA and for standardizing and enhancing communication between rheumatologists and radiologists to improve diagnosis and patient care.Disclosure of InterestsTorsten Diekhoff Paid instructor for: Novarits, Eli Lilly, MSD, Canon MS, Consultant of: Eli Lilly, Iris Eshed: None declared, Chiara Giraudo: None declared, Kay-Geert Hermann: None declared, Manouk de Hooge: None declared, Lennart Jans: None declared, Anne Grethe Jurik: None declared, Robert G Lambert: None declared, Pedro M Machado: None declared, Walter P Maksymowych: None declared, Michael Mallinson: None declared, Helena Marzo-Ortega: None declared, Victoria Navarro-Compán: None declared, Susanne Juhl Pedersen: None declared, Mikkel Østergaard: None declared, Monique Reijnierse: None declared, Martin Rudwaleit: None declared, Fernando Sommerfleck: None declared, Ulrich Weber: None declared, Xenofon Baraliakos: None declared, Denis Poddubnyy: None declared

Abstract
BackgroundA Treat-to-Target approach (T2T) is broadly considered to lead to better clinical outcomes and recommended in patients with RA. However, very few studies have analyzed the effect of T2T on radiographic progression, and any such studies have provided inconsistent results.ObjectivesTo investigate whether meticulously following a treat-to-target (T2T)-strategy in daily clinical practice leads to lower radiographic progression in RA.MethodsPatients from the multicenter RA-BIODAM cohort with ≥2 consecutive visits with radiographs available were included. In RA-BIODAM patients were enrolled as they were initiating a new csDMARD/bDMARD treatment were followed-up with the intention to benchmark and intensify treatment. The primary outcome of this analysis was the change in Sharp-van der Heijde score (SvdH, 0-448), assessed every 6 months, using average scores from 2 readers (scores with known chronological order). Following a DAS44-T2T remission strategy, which was defined at each 3-month visit, was the main variable of interest. Patients were categorized based on the proportion of visits in which T2T was followed according to our definition: very low (≤40% of the visits, low (>40%, <62.5%), high (≥62.5%, ≤75%) and very high (>75%). Radiographic progression at 2 years was visualized across groups by cumulative probability plots. Per 3-month interval T2T could be followed zero, one or two times (in a total of 2 visits). Associations between the number of visits with T2T in an interval and radiographic progression, both in the same and in the subsequent 6-month interval, were analysed by generalised estimating equations, adjusted for age, gender, disease duration and country.ResultsIn total, 511 patients were included (mean (SD) age: 56 (13) years; 76% female). After 2 years, patients showed on average 2.2 (4.1) units progression (median:1 unit). Mean (SD) 2-year progression was not significantly different across categories of T2T: very low: 2.1 (2.7)-units; low: 2.8 (6.0); high: 2.4 (4.5), very high: 1.6 (2.2) (Figure 1). Meticulously following-up T2T in a 3-month interval neither reduced progression in the same 6-month interval (parameter estimates (for yes vs no): +0.15 units (95%CI: -0.04 to 0.33) for 2 vs 0 visits; and +0.08 units (-0.06;0.22) for 1 vs 0 visits) nor did it reduce progression in the subsequent 6-month interval (Table 1).Table 1.Effect of following DAS44-remission-T2T strategy on 6-month radiographic progression over 2 yearsChange in radiographic damage(regression coefficient (95% CI))N=506T2T during 3 months on radiographic progression in the same 6-month period 2 visits vs 0 followed0.15 (-0.04; 0.33) 1 visit vs 0 followed0.08 (-0.06; 0.22)T2T during 3 months on radiographic progression in the subsequent 6-month period 2 visits vs 0 followed-0.09 (-0.28; 0.10) 1 visit vs 0 followed-0.10 (-0.24; 0.05)Figure 1.Cumulative probability plot with 2-year radiographic progression according to the proportion of 3-monthly visits with T2T followedConclusionIn this daily practice cohort, more meticulously following T2T principles did not result in more reduction of radiographic progression than a somewhat more liberal attitude toward T2T. One possible interpretation of these results is that the intention to apply T2T already suffices and that a more stringent approach does not further improve outcome.AcknowledgementsBIODAM was financially supported by an unrestricted grant from AbbVieDisclosure of InterestsSofia Ramiro Speakers bureau: Eli Lilly, MSD, Novartis, UCB, Consultant of: AbbVie, Eli Lilly, MSD, Novartis, Pfizer, UCB, Sanofi, Grant/research support from: AbbVie, Galapagos, Novartis, Pfizer, UCB, Robert B.M.

Abstract
BackgroundMagnetic resonance tomography (MRI) plays a key role in the early diagnosis of axial spondyloarthritis (axSpA). However, the detection of changes indicative of axSpA requires specific expertise, which poses a challenge to non-specialized centers. Deep learning (an advanced machine learning method) based on training an artificial neural network may facilitate and support diagnostics in clinical practice.ObjectivesTo create a reliable deep learning tool for the detection of active inflammatory and structural changes indicative of axSpA on MRI of sacroiliac joints.MethodsIn this study, MRIs of sacroiliac joints from 477 patients from four cohorts (GESPIC-AS, GESPIC-Crohn, GESPIC-Uveitis and OptiRef comprising 266 patients with and 211 without axSpA) were used to develop a deep learning framework (randomly divided into training, n=404, and validation, n=73, datasets). MRIs from the ASAS cohort (n=116) were used for independent testing (test dataset). Each examination in the training/validation dataset was evaluated for the presence of active inflammatory and structural changes indicative of SpA by six experienced, trained and calibrated readers and by seven expert readers in the test dataset. The presence of the changes was defined as the majority vote amongst readers. Discordant cases in the training/validation dataset underwent consensus reading. In addition, the test dataset was evaluated by three radiologists not specifically trained in SpA. Diagnostic performance was evaluated using the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity and specificity.ResultsThe prevalence of positive imaging findings for active inflammatory/structural changes indicative of axSpA was 41%/51% in the training/validation dataset and 22%/22% in the test dataset. The model for the detection of active inflammatory changes showed an AUC of 0.91 (0.83 – 0.97) – Figure 1 – and an accuracy of 84% on the validation dataset; the corresponding sensitivity and specificity were 96% and 76%, respectively. Despite a substantially lower prevalence of active inflammatory changes in the test dataset, the model showed good generalization with an AUC of 0.91 (0.84−0.97) and an accuracy of 75%; the sensitivity and specificity were 88% and 71%, respectively. The model demonstrated a similar performance on the validation and test datasets for the detection of active inflammatory changes fulfilling the ASAS definition. The model for the detection of structural changes indicative of axSpA showed good performance on the validation dataset with an AUC of 0.90 (0.82-0.96) for the detection of structural changes and an overall accuracy of 85%. The associated sensitivity and specificity were 95% and 75%, respectively. The model showed reasonable generalization to new data with an AUC of 0.89 (0.81−0.96) and an accuracy of 79%; the sensitivity and specificity were 85% and 78%, respectively. Overall, the model performed close to the individual human experts - Figure 1.ConclusionThe developed framework allowed the detection of active inflammatory and structural changes indicative of axSpA on MRI. This approach may be used as an assistant tool in the diagnostic workflow.AcknowledgementsGESPIC-AS has been financially supported by the German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung - BMBF).

Abstract
BackgroundCytokines such as tumor necrosis factor (TNFα) have been shown to elicit inflammatory and catabolic events in the joints of patients with osteoarthritis. Recent RCTs demonstrated that TNFα inhibition has no effect on pain and MRI-detected synovitis or bone marrow lesions in patients with erosive hand OA1-3. However, the progression of bone erosions was reduced in a subgroup of patients with more clinically swollen distal interphalangeal joints in one RCT1. Consequently, it remains possible that TNFα inhibition may have beneficial effects in specific subgroups of patients with a high inflammatory component.ObjectivesWe aimed to evaluate the efficacy and safety of a TNFα inhibitor, adalimumab (ADA), in a proof-of-concept study in patients with inflammatory OA of the knee.MethodsOKINADA was a 52-week, randomized, double-blind, placebo-controlled, parallel-group study done at 11 sites in Canada (NCT02471118). Eligible participants were adults (aged ≥18 years) with a diagnosis of OA of the index knee and classified according to American College of Rheumatology criteria, including radiological evidence of OA (Kellgren-Lawrence grades 2 or 3) with clinical signs of knee effusion. Subjects had persistent knee pain of ≥ one month duration with a pain score of ≥ 4 (0-10 NRS) in the index knee at screening and baseline despite conventional treatment with maximum tolerated acetaminophen and/or non-steroidal anti-inflammatory drug. Patients were randomly assigned (1:1) to receive subcutaneous 40 mg ADA every 2 weeks or placebo (PBO). Primary endpoint was the Outcome Measures in Rheumatology and Osteoarthritis Research Society International set of responder criteria (OMERACT-OARSI) at week 16 defined as: (1) improvement in pain or function ≥50% and an absolute change ≥20 mm; or (2) improvement of ≥20% with an absolute change ≥10 mm in at least two of the following three categories: pain, function, and patient’s global assessment. Secondary endpoints included: the Knee Injury and Osteoarthritis Outcome Score (KOOS) for the domains of pain, activities of daily living (ADL), OA symptoms, sport and recreation function (SRF), and knee-related quality of life (QoL), patient’s global assessment of disease status (PGAD), investigator global assessment of disease status (IGAD), and expanded Target Joint Assessment (TJA) score.ResultsA total of 59 patients were randomized (29 to PBO, 30 to ADA). The primary endpoint was not met: OMERACT-OARSI combined (ADA: 9 [30.0%] vs PBO: 7 [24.1%], p=0.62). For KOOS pain, ≥20% improvement was noted in 11 (36.7%) ADA vs 7 (24.1%) PBO patients (p=0.30), and ≥50% improvement in 5 (16.7%) ADA vs 6 (20.7%) PBO patients (p=0.69). There were no significant treatment-group differences in baseline to 16-week change in continuous secondary endpoints (ADA vs PBO: KOOS ADL 6.5 vs 8.4 (p=0.71), KOOS QoL 10.1 vs 7.4 (p=0.66), KOOS symptoms 7.8 vs 11.5 (p=0.42), KOOS SRF 5.8 vs 7.7 (p=0.76), PGAD -1.0 vs 0.1 (p=0.10), IGAD -1.5 vs -2.1 (p=0.30), TJA -2.4 vs -2.2 (p=0.87) or in lab markers (ESR, CRP). There were 11 withdrawals (4 ADA, 7 PBO) of which 2 were for adverse events (1 ADA, 1 PBO) and 2 for increasing knee pain (1 ADA, 1 PBO). No new safety signals were identified and there were no serious adverse events.ConclusionAlthough the treatment was safe, short-term treatment with anti-TNFα therapy does not appear to provide clinically meaningful improvements in OA symptoms in patients with established radiographic knee OA. Analyses of structural endpoints will be reported when results are available.References[1]Verbruggen G, et al. Ann Rheum Dis 2012; 71: 891-8.[2]Chevalier X, et al.

Abstract
BackgroundJanus kinase (JAK) inhibitors have been recognized as a potential therapeutic option in ankylosing spondylitis (AS), also known as radiographic axial spondyloarthritis (r-axSpA).1 Upadacitinib (UPA), a JAK inhibitor, has demonstrated efficacy and safety in the treatment of AS2; however, no JAK inhibitor studies have been conducted in non-radiographic axSpA (nr-axSpA) to date.ObjectivesTo assess the efficacy and safety of UPA in patients (pts) with active nr-axSpA.MethodsSELECT-AXIS 2 (NCT04169373) was conducted under a master protocol comprising two independent studies, one in an AS population with an inadequate response to biologic disease-modifying antirheumatic drugs and one in an nr-axSpA population. The nr-axSpA study is a randomized, double-blind, placebo(PBO)-controlled, phase 3 trial that enrolled adults ≥18 years with a clinical diagnosis of nr-axSpA (who also fulfilled 2009 ASAS classification criteria for axSpA but did not meet the radiologic criterion of modified New York criteria), who had objective signs of active inflammation consistent with axSpA on MRI of the sacroiliac (SI) joints and/or high sensitivity C-reactive protein (hs-CRP) >upper limit of normal (2.87 mg/L) at screening, and who had BASDAI and pt’s assessment of total back pain scores ≥4 based on a 0 to 10 numeric rating scale at study entry. Pts were randomized 1:1 to receive oral UPA 15 mg once daily (QD) or PBO during a 52-week (wk) double-blind treatment period. The primary endpoint was ASAS40 response at wk 14. Multiplicity-controlled secondary endpoints assessed at wk 14 included BASDAI50, ASDAS ID (<1.3), ASDAS LDA (<2.1), ASDAS PR, and ASAS20, and the change from baseline (Δ) in ASDAS (CRP), SPARCC MRI SI joint inflammation score, total and nocturnal back pain, BASFI, ASQoL, ASAS HI, BASMI, and MASES. Treatment-emergent adverse events (TEAEs) are reported through wk 14 for pts who received ≥1 dose of study drug.ResultsOf 314 pts randomized at baseline, 313 received study drug (UPA 15 mg, n=156; PBO, n=157) and 295 (94%) received study drug through wk 14. Baseline demographic and disease characteristics were balanced across treatment groups and consistent with an active nr-axSpA population (58% female; mean age 42.1 years; mean BASDAI 6.9; mean hs-CRP 12.1 mg/L). A significantly higher ASAS40 response rate at wk 14 was achieved with UPA vs PBO (45% vs 23%; P<0.0001; Figure 1). Statistical significance was also achieved in the first 12 of the 14 multiplicity-controlled secondary endpoints (ie, all endpoints except BASMI and MASES) at wk 14 for UPA compared with PBO (P<0.01; Figure 1). The proportion of pts who experienced a TEAE was similar between treatment groups (UPA, 48%; PBO, 46%). Serious TEAEs and TEAEs leading to discontinuation were reported in 4 (2.6%) pts treated with UPA and 2 (1.3%) pts treated with PBO, respectively. Few pts had serious infection or herpes zoster (each 2 [1.3%] pts on UPA; each 1 [0.6%] pt on PBO, respectively). Uveitis was reported in 1 (0.6%) pt on UPA who had a history of uveitis and none on PBO. No malignancy other than non-melanoma skin cancer, major adverse cardiovascular events, venous thromboembolic events, inflammatory bowel disease (IBD), or death were reported in the study; 1 event of basal cell carcinoma occurred with PBO.ConclusionUPA 15 mg QD demonstrated significantly greater improvements in disease activity, pain, function, quality of life, and MRI-detected SI joint inflammation than PBO after 14 wks of treatment in pts with active nr-axSpA. The safety profile of UPA was consistent with what has been observed with other inflammatory musculoskeletal diseases,3–5 and no new risks were identified. These results support the potential use of UPA in pts with active nr-axSpA.References[1]Ward MM, et al. Arthritis Rheumatol. 2019;71(10):1599–63.[2]van der Heijde D, et al.

Abstract
BACKGROUND The current core outcome set for ankylosing spondylitis (AS) has had only minor adaptations since its development 20 years ago. Considering the significant advances in this field during the preceding decades, an update of this core set is necessary. OBJECTIVE To update the ASAS-OMERACT core outcome set for AS into the ASAS-OMERACT core outcome set for axial spondyloarthritis (axSpA). METHODS Following OMERACT and COMET guidelines, an international working group representing key stakeholders (patients, rheumatologists, health professionals, pharmaceutical industry and drug regulatory agency representatives) defined the core domain set for axSpA. The development process consisted of: i) Identifying candidate domains using a systematic literature review and qualitative studies; ii) Selection of the most relevant domains for different stakeholders through a 3-round Delphi survey involving axSpA patients and axSpA experts; iii) Consensus and voting by ASAS; iv) Endorsement by OMERACT. Two scenarios are considered based on the type of therapy investigated in the trial: symptom modifying therapies and disease modifying therapies. RESULTS The updated core outcome set for axSpA includes 7 mandatory domains for all trials (disease activity, pain, morning stiffness, fatigue, physical function, overall functioning and health, and adverse events including death). There are 3 additional domains (extra-musculoskeletal manifestations, peripheral manifestations and structural damage) that are mandatory for disease modifying therapies and important but optional for symptom modifying therapies. Finally, 3 other domains (spinal mobility, sleep, and work and employment) are defined as important but optional domains for all trials. CONCLUSION The ASAS-OMERACT core domain set for AS has been updated into the ASAS-OMERACT core domain set for axSpA. The next step is the selection of instruments for each domain.

Abstract
Magnetic resonance imaging (MRI) is an increasingly important tool for identifying involvement of the sacroiliac joints (SIJ) in juvenile idiopathic arthritis (JIA). The key feature for diagnosing active sacroiliitis is bone marrow edema (BME), but other features of active arthritis such as joint space inflammation, inflammation in an erosion cavity, capsulitis and enthesitis can be seen as well. Structural changes may also be seen. Systematic MRI assessment of inflammation and structural damage may aid in monitoring the disease course, choice of therapeutics and evaluating treatment response. In this pictorial essay, we illustrate normal MRI findings and growth-related changes of the SIJ in the pediatric population, as well as the different MRI features of SIJ inflammation. This atlas demonstrates fundamental MRI disease features of active inflammation in a format that can serve as a reference for assessing SIJ arthritis according to the updated preliminary JAMRIS (Juvenile Idiopathic Arthritis MRI Score) scoring system proposed by the MRI in JIA working group of Outcome Measures in Rheumatology and Clinical Trials (OMERACT). The atlas is intended to be read in conjunction with its companion Part 2, Structural Lesions.

Abstract
Background:Randomized controlled trials have targeted reducing the size of BML and degree of synovitis for the treatment of OA. We have developed the OMERACT Knee Inflammation MRI Scoring System (KIMRISS) and have recently refined it to maximize reliability and sensitivity to change. Innovations include electronic overlays for assessment of BML in 500 subregions, a web-based interface with direct online scoring, and real-time iterative calibration (RETIC) prior to reading exercises. Synovitis-effusion (S-E) is also scored on all consecutive sagittal slices on a web-based interface.Objectives:We aimed to test the feasibility, reliability, and responsiveness of KIMRISS versus an established method, MOAKS, in two multi-reader exercises.Methods:KIMRISS incorporates web-based graphic overlays for each of femur, tibia, and patella (range 0-500). S-E is recorded as the largest diameter perpendicular to the longest axis of this feature (range 0-100). All scores are pro-rated for a standardized number of MRI slices. In a pre-reading exercise for KIMRISS, readers scored sufficient cases in RETIC to attain scoring proficiency, pre-specified as an ICC of ≥0.80 and ≥0.70 for status and change scores of BML and S-E compared to developer reads. A new web-based scoring platform with overlays designating different subregions for scoring BML was developed for MOAKS. We compared reliability for status and change scores of BML and S-E in 2 international multi-reader exercises of baseline and one-year MRI scans from the Osteoarthritis Initiative: A. 4 expert readers and an OMERACT fellow scored 38 cases selected for MOAKS BML score ≥1. B. 7 expert readers and an OMERACT fellow scored 60 cases selected for MOAKS BML ≥3 and Kellgren-Lawrence (K-L) grade <3. Reliability was assessed by intra-class correlation coefficient (ICC) and Smallest Detectable Change (SDC), responsiveness by the standardized response mean (SRM), and feasibility using the System Usability Scale (SUS scoring range 0-100).Results:For exercises A/B, subjects were 55.3%/ 26.7% male, mean(±SD) age 61.7(±9.1)/61.9(8.8) years, and radiographic K-L grade ≤2 in 39.4%/100%. Change was small in both exercises (<5% of scoring range for KIMRISS and MOAKS BML and S-E) with comparable responsiveness (Table 1). Despite this, ICC for change was consistently good to very good for both BML and S-E and consistently better for KIMRISS (Table 1). Mean SUS scores were 88.2 for KIMRISS and 54.3 for MOAKS.Table 1.KIMRISS and MOAKS scores in Two International Multi-reader ExercisesMethodMRI featureScores mean (SD)SDC(% of max)P valueSRMBaselineOne-year Follow upChangeEXERCISE AMOAKSBML3.6 (2.9)3.4 (2.3)-0.2 (1.9)1.0 (2.2%)0.72-0.11Synovitis-effusion1.3 (0.8)1.5 (0.8)0.2 (0.4)0.4 (13.3%)0.0170.5KIMRISSBML15.7 (13.3)21.2 (22.5)5.5 (15.3)5.6 (1.1%)0.0220.36Synovitis-effusion21.8 (12.0)24.3 (11.9)2.5 (7.4)2.8 (2.8%)0.0430.34EXERCISE BMOAKSBML4.2 (2.6)3.7 (2.4)-0.5 (2.1)1.1 (2.4%)0.083-0.24Synovitis-effusion1.2 (0.7)1.3 (0.8)0.0 (0.5)0.4 (13.3%)0.590.0KIMRISSBML18.0 (17.5)15.9 (14.3)-2.1 (12.3)5.9 (1.2%)0.19-0.17Synovitis-effusion21.8 (9.3)22.9 (10.8)1.1 (7.1)2.2 (2.2%)0.250.15Intra-class Correlation Coefficients (95%CI)MethodMRI featureExercise AExercise BKIMRISS statusKIMRISS changeBML0.86 (0.78-0.92)0.88 (0.81-0.93)0.80 (0.70-0.87)0.72 (0.64-0.80)MOAKS statusMOAKS changeBML0.71 (0.46-0.85)0.76 (0.64-0.85)0.67 (0.56-0.77)0.69 (0.60-0.78)KIMRISS statusKIMRISS changeSynovitis-effusion0.88 (0.81-0.93)0.87 (0.79-0.92)0.75 (0.52-0.86)0.87 (0.82-0.91)MOAKS statusMOAKS changeSynovitis-effusion0.66 (0.4-0.79)0.52 (0.36-0.67)0.65 (0.52-0.75)0.48 (0.37-0.60)Conclusion:The KIMRISS method for scoring BML and Synovitis-Effusion scores highly for feasibility and demonstrates consistently high reliability when compared to MOAKS.

Abstract
Background:There is no international consensus on the optimal number of slices for evaluation of MRI structural lesions in the SIJ. An “all slice” method evaluates lesions from the most anterior slice, defined as the first slice with vertical height of ≥1cm of the SIJ joint cavity, up to the most posterior slice, defined as the most posterior slice where ≥1cm vertical height of the cartilaginous portion is still visible. The SPARCC method scores the transitional slice between cartilaginous and ligamentous compartments as the first slice and then an additional 4 slices anterior to the transitional slice.Objectives:We aimed to investigate inter-reader reliability, the extent of detection of lesions, and frequency of cases with a positive MRI for structural lesions when using an “all slice” approach versus the SPARCC scoring of 5 central slices.Methods:MRI T1W images with DICOM series were available from 148 cases who had MRI performed in the ASAS-Classification Cohort. Seven central readers recorded MRI lesions in an eCRF that recorded global assessments of presence/absence of changes suggestive of axSpA and structural lesions typical of axSpA. Structural lesions per the ASAS definitions were also recorded in consecutive semicoronal slices using the “all slice” approach, but also recording the transitional slice, according to their presence/absence in SIJ quadrants (erosion, fat lesion, sclerosis) or halves (backfill, ankylosis). Structural lesion frequencies were assessed descriptively according to majority agreement (≥4/7) of central readers and also any 2 central readers. Reliability for detection of MRI lesions was compared between central and local readers using the ICC.Results:The mean (SD) (range) number of anterior and posterior slices peripheral to the 5 central slices was 1.0 (1.0) (0-4) and 2.2 (1.8) (0-6) per case, respectively. There were 2 cases (1.4%) where ≥2 readers scored structural lesions in peripheral slices but not in the 5 central slices. The mean percentage of the total structural lesion score that was captured by the 5 central slices was >75% for all types of lesions except ankylosis (59%) (Table 1). Inter-reader reliability was greater for all lesions when assessing the 5 central slices and especially for erosion and backfill (Table 1).Conclusion:The major component of structural lesion data is captured by assessment of 5 slices, which includes the transitional slice and the subsequent 4 anterior slices. Moreover, reliability for detection of structural lesions is substantially worse in peripheral slices.MRI Lesion“All slice”Central 5 slicesPeripheral slicesP value central vs peripheral slicesP value“all slice” vs central slicesMean (SD) Lesion Score Per CaseErosion2.4 (4.5) (0-22.9)1.8(3.4) (0-17.1)0.6 (1.4) (0-10.1)<0.001< 0.001Fat lesion2.5 (5.9) (0-34.0)1.8 (4.5) (0-25.1)0.7 (1.8) (0-9.9)< 0.001<0.001Sclerosis2.0 (4.9) (0-39.0)1.5 (3.6) (0-26.1)0.5 (1.5) (0-12.9)< 0.001<0.001Backfill0.5 (1.5) (0-12)0.4 (1.2) (0.0-9.3)0.1 (0.4) (0-2.7)< 0.0010.84Ankylosis0.5 (3.4) (0-30.7)0.3 (2.3) (0-20.0)0.2 (1.2) (0-11.3)0.100.18Mean (SD) (Range) % of Total Lesion Score in Central vs Peripheral slicesErosion100%76.4% (28.9%) (0-100%)23.6% (28.9%) (0-100%)<0.001NAFat lesion100%75.4% (26.5%) (0-100%)24.6% (26.5%) (0-100%)<0.001NASclerosis100%79.5% (22.9%) (0-100%)20.5% (22.9%) (0-100%)<0.001NABackfill100%86.0% (20.2%) (0-100%)14.0% (20.2%)(0-100%)<0.001NAAnkylosis100%59.0% (36.4%) (0-100%)41.0% (36.4%) (0-100%)0.56NAICC of 7 readers (Mean (SD) (Range))MRI lesionAll slicesCentral 5 slicesPeripheral slicesErosion0.54 (0.15) (0.28-0.84)0.58 (0.13) (0.34-0.85)0.40 (0.17) (0.10-0.66)Fat lesion0.61 (0.18) (0.30-0.89)0.63 (0.16) (0.35-0.88)0.52 (0.20) (0.19-0.82)Sclerosis0.73 (0.18) (0.36-0.94)0.73 (0.16) (0.36-0.91)0.67 (0.19) (0.27-0.94)Backfill0.37 (0.21) (0.10-0.85)0.39 (0.19) (0.14-0.83)0.18 (0.23) (0.0-0.80)Ankylosis0.97 (0.02) (0.91-0.99)0.99 (0.01) (0.97-1.0)0.85 (0.10) (0.62-0.98)Disclosure of Interests:None declared.

Abstract
Background:The oral Janus kinase 1 preferential inhibitor filgotinib (FIL) significantly improved Spondyloarthritis Research Consortium of Canada (SPARCC) magnetic resonance imaging (MRI) inflammation scores (bone marrow oedema) in the spine and sacroiliac joints vs placebo (PBO) in the Phase 2 TORTUGA trial (NCT03117270) in patients with active ankylosing spondylitis (AS).1Objectives:This post-hoc analysis evaluated the effects of FIL on Canada-Denmark (CANDEN) MRI measures of spinal inflammation and structural lesions in patients from the TORTUGA trial.Methods:TORTUGA was a PBO-controlled, multicentre, double-blind, randomised trial. Patients with active AS (as per modified New York classification criteria, with sacroiliitis confirmed by central reading) were treated with FIL 200 mg (n=58) or PBO (n=58) once daily for 12 weeks. MRI of the total spine was conducted at baseline and at treatment end. Scans were re-evaluated post-hoc by 2 independent experts (blinded to time point and assigned treatment) using the CANDEN method;2 inter-reader discrepancies were resolved by an independent adjudicator. Observed changes from baseline were evaluated using analysis of covariance, with factors for treatment, baseline value, and randomisation stratification by prior tumour necrosis factor inhibitor use. Least-squares (LS) mean changes from baseline and between-group differences with 95% confidence intervals (CI) were calculated; P values are nominal.Results:MRI scans from 88 patients (47 FIL, 41 PBO) with an evaluable scan at baseline and Week 12 (or early termination) were re-evaluated. Baseline characteristics were generally similar between patients with/without an MRI scan. Of those with MRI scans, mean total spine inflammation score (which ranges from 0–614) was higher, and mean ankylosis score (which ranges from 0–460) was lower, in the FIL vs PBO group at baseline. Total spine inflammation scores decreased from baseline with FIL but not with PBO (Figure and Table; P=0.0003 for between-group difference). Cumulative probability plots favoured FIL over PBO for change from baseline in subregion inflammation scores, including posterolateral elements (i.e. sum of lesions in ribs, transverse processes, spinous processes, soft tissue inflammation, and postero-lateral vertebral body), facet joint, and vertebral body. Total spine fat lesion scores numerically increased from baseline in the FIL but not PBO group (P=0.0878 for between-group difference; Table). There were no significant differences between groups for changes in erosion (P=0.1956) or ankylosis (P=0.3888) scores (Table).Table 1.Change from baseline at Week 12 in CANDEN total spine inflammation, total spine fat, total spine bone erosion, and ankylosis scoresTreatment groupnSample mean (SE)LS mean (SE)95% CI of treatment meanLS mean of group difference (SE)95% CI of group differenceBetween-group P valueTotal spine inflammation scoreFilgotinib47–4.98 (0.96)–4.40 (1.13)–6.65, –2.15–4.49 (1.21)–6.85, –2.120.0003Placebo410.29 (0.78)0.09 (1.13)–2.17, 2.34Total spine fat scoreFilgotinib471.01 (0.62)1.09 (0.66)–0.22, 2.401.18 (0.69)–0.18, 2.550.0878Placebo41–0.25 (0.19)–0.09 (0.66)–1.40, 1.21Total spine bone erosion scoreFilgotinib470.01 (0.02)0.07 (0.03)0.00, 0.140.05 (0.04)–0.02, 0.120.1956Placebo41–0.02 (0.03)0.02 (0.03)–0.04, 0.09Total ankylosis scoreFilgotinib470.30 (0.29)0.23 (0.31)–0.40, 0.850.28 (0.34)–0.37, 0.940.3888Placebo41–0.01 (0.08)–0.06 (0.31)–0.68, 0.56SE, standard errorConclusion:This is the first PBO-controlled trial to demonstrate a decrease in inflammatory activity with FIL, not only in the spinal vertebrae but also in the postero-lateral elements of the spine and facet joints. As expected in a 12-week study period, no changes in erosion or ankylosis were seen, while fat lesions showed a tendency to increase with FIL.

Abstract
Background:Inflammation in peripheral joints and entheses is common in spondyloarthritis (SpA). Whole-body magnetic resonance imaging (WB-MRI) allows assessment of the overall inflammatory status of arthritis patients including joints and entheses. The OMERACT MRI Whole-body scoring system for Inflammation in Peripheral joints and Entheses (MRI-WIPE) [1] has been developed and validated for the entire body assessment, including the knee, but not separately validated for the knee joint region. Detailed MRI scoring systems exist for heels, hands and feet, but although knee arthritis is a key cause of functional impairment, no detailed scoring system has been validated for inflammatory arthritides. The Knee Inflammation MRI Scoring System (KIMRISS) [2] was developed and validated in osteoarthritis and demonstrated good reliability.Objectives:To perform region-based development of whole-body MRI through validation of two knee region scoring systems in SpA.Methods:Assessment of inflammation was performed in the knee region on sagittal WB-MRIs using 2 scoring systems, MRI-WIPE and KIMRISS (Figure 1), in 4 iterative multi-reader exercises. In the final exercise, images (psoriatic arthritis, axial and peripheral SpA) were obtained before and after TNF-inhibitor.Results:In the final exercise (exercise 4), reliability was mostly good for experienced readers with the overall highest interreader agreement in the previous exercise (exercise 3). Median pairwise single measure intraclass correlation coefficients for osteitis and synovitis/effusion for status/change were 0.71/0.48 (WIPE osteitis), 0.48/0.77 (WIPE synovitis/effusion), 0.59/0.91 (KIMRISS osteitis) and 0.92/0.97 (KIMRISS synovitis/effusion) (Table 1). Wilcoxon signed-rank test showed significant change in synovitis/effusion for both methods and they correlated significantly regarding status in osteitis (0.92, p<0.001) and synovitis/effusion (0.89, p=0.001) and change in synovitis/effusion (0.89, p<0.001). Standardized response mean was 0.74 (WIPE synovitis/effusion) and 0.78 (KIMRISS synovitis/effusion).Table 1.MRI-WIPE knee and KIMRISS interreader reliability for OMERACT exercises 3 and 4MRI-WIPE KneeKIMRISSOsteitisSynovitis/effusionOsteitisSynovitis/effusionVariablesNo. patientsType of scoreMean scoreICCMean scoreICCMean scoreICCMean scoreICCExercise 39 readers11Status3.6 (0-16)0.57 (-0.06-0.98)1.8 (0-4)0.47 (0.05-0.85)32.3 (1-224)0.87 (0.66-0.99)29.9 (11-60)0.34 (-0.62-0.87)11Change1.1 (-2-6)0.53 (0.03-0.90)0 (-2-1)0.32 (-0.13-0.76)27.7 (-9-131)0.58 (-0.30-0.96)-1.6 (-33-11)0.48 (-0.32-0.95)Exercise 33 readers11Status3.1 (0-16)0.83 (0.71-0.97)2.5 (0-5)0.59 (0.51-0.71)34.4 (0-233)0.89 (0.83-0.99)36.5 (16-78)0.59 (0.08-0.86)11Change0.9 (-3-6)0.72 (0.57-0.83)0 (-2-1)0.63 (0.49-0.76)19.3 (-23-86)0.46 (0.18-0.83)-1.8 (-45-17)0.89 (0.82-0.95)Exercise 49 readers10Change-0.25 (-4-5)0.38 (-0.35-0.94)-1.0 (-3-1)0.30 (-0.43-0.89)-0.45 (-37-65)0.26 (-0.86-0.97)-14.7 (-48-0.20)0.48 (-0.39-0.99)20Status2.9 (0-7)0.50 (-0.01-0.84)2.1 (0-4)0.44 (-0.21-0.79)15.2 (0-66)0.35 (-0.04-0.89)55.6 (1-122)0.54 (0.01-0.96)Exercise 43 readers10Change0.2 (-2-6)0.48 (0.16-0.66)-1.4 (-5-0)0.77 (0.70-0.82)5.8 (-27-111)0.92 (0.90-0.94)-20.7 (-65-28)0.97 (0.96-0.98)20Status2.3 (0-6)0.71 (0.60-0.80)2.7 (0-5)0.48 (0.42-0.57)11.4 (0-36)0.59 (0.39-0.71)69.4 (1-153)0.91 (0.87-0.93)Sum scores are mean (range) of the patients scores.

Abstract
Background:Preliminary definitions for SIJ lesions in the OMERACT Juvenile Idiopathic Arthritis Magnetic Resonance Imaging score has been reported1.

Abstract
Background:Whole-body MRI (WB-MRI) allows assessment of the overall inflammation in arthritis patients, including joint and entheses. To enhance the use of WB-MRI in clinical trials, the OMERACT MRI in Arthritis Working Group developed the OMERACT MRI Whole-body score for Inflammation in Peripheral joints and Entheses in inflammatory arthritis (MRI-WIPE) [1]. This has been validated for the entire body, including the hip/pelvis region, but not for each individual region. More detailed scoring systems exist for heels, hands and feet but although hip arthritis is a key cause of functional impairment in spondyloarthritis (SpA), no detailed scoring system has been published for use in SpA. The Hip Inflammation Magnetic Resonance Imaging Scoring System (HIMRISS) was developed and validated in osteoarthritis showing good reliability.Objectives:To validate reliability, correlation and responsiveness of two WB-MRI scores for the hip/pelvis region in SpA.Methods:Inflammation in the hip/pelvis region was assessed on coronal WB-MRIs in 4 iterative multi-reader exercises using MRI-WIPE for the hip/pelvis region and HIMRISS (Figure 1). In final exercises, images (axial/peripheral SpA and psoriatic arthritis) were obtained before and after TNF-inhibitor.Results:In final exercises reliability was mostly good for the best calibrated readers. Median single-measure intraclass correlation coefficients were 0.58-0.65 (WIPE osteitis), 0.10-0.88 (HIMRISS osteitis), 0.38-0.72/0.52-0.60 (WIPE synovitis/effusion) and 0.68-0.89/0.78-0.85 (HIMRISS synovitis/effusion) (Table 1). The methods correlated significantly for status in osteitis (0.72, p=0.019) and for synovitis/effusion status (0.83, p=0.003) and change (0.73, p=0.017) (Table 1). In exercise 4 Wilcoxon signed-rank test showed significant change in osteitis between timepoints using WIPE hip/pelvis and SRM was large (1.23), while lower for WIPE synovitis/effusion and HIMRISS.Table 1.MRI-WIPE hip/pelvis and HIMRISS interreader reliability for OMERACT exercises 3-4MRI-WIPE hip/pelvisHIMRISSOsteitisSynovitis/effusionOsteitisSynovitis/effusionVariablesNo. patients(cases)Type of scoreMeanscoreICCMeanscoreICCMeanscoreICCMeanscoreICCExercise 39 readers11Status2.3 (0-10)0.69 (0.23-0.93)1.4 (0-4)0.58 (-0.06-0.96)8.2 (1-60)0.84 (0.56-0.99)12.8 (3-25)0.52 (0.00-.91)11Change-0.2 (-1-1)NA-0.2 (-3-1)0.50 (0.10-0.87)-0.35 (-3-1)NA-1.8 (-17-10)0.50 (-0.05-0.89)Exercise 33 readers11Status1.8 (0-10)0.63 (0.46-0.93)1.7 (0-5)0.60 (0.34-0.80)6.6 (0-65)0.88 (0.77-0.94)12.8 (2-28)0.89 (0.87-0.91)11Change-0.12 (-1-1)NA-0.12 (-3-2)0.60 (0.48-0.83)-0.7 (-7-0)NA-1.6 (-21-8)0.78 (0.70-0.87)Exercise 49 readers10 (1-10)Status1.2 (0-4)0.21 (-0.39-0.91)1.1 (0-2)0.19 (-0.31-0.69)1.8 (0-6)0.07 (-0.17-0.83)16.4 (9-23)0.31 (0.00-0.89)10 (11-20)Status1.6 (0-6)0.51 (-0.08-0.99)1 (0-3)0.40 (-0.17-0.88)3.5 (1-8)0,08 (-0.21-0.95)11.2 (5-24)0.49 (0.00-0.94)10 11-20)Change-0.4 (-2-0)NA-0.39 (-2-0)0.22 (-0.68-0.83)-2.2 (-7-2)NA-5.2 (-18-0)0.57 (0.02-0.92)20 (1-20)Status1.4 (0-6)0.41 (-0.35-0.92)1.0 (0-3)0.27 (-0.07-0.75)2.7 (0-9)0.09 (-0.17-0.85)13.8 (5-25)0.45 (0.01-0.90)Exercise 43 readers10 (1-10)Status0.8 (0-4)0.29 (0.01-0.78)1.3 (0-2)-0.02 (-0.29-0.12)0.4 (0-2)-0.04 (-0.04-0.04)15.8 (5-26)0.73 (0.59-0.89)10 (11-20)Status1.8 (0-9)0.65 (0.52-0.76)1.2 (0-4)0.72 (0.62-0.81)1.7 (0-5)0.06 (-0.17-0.35)9.2 (2-26)0.68 (0.53-0.88)10 (11-20)Change-0.6 (-2-0)NA-0.5 (-3-1)0.52 (0.49-0.55)-0.2 (-2-1)NA-2.8 (-19-6)0.85 (0.82-0.88)20 (1-20)Status1.3 (0-9)0.58 (0.43-0.69)1.2 (0-4)0.38 (0.31-0.44)1.0 (0-5)0.10 (-0.09-0.33)12.5 (2-26)0.73 (0.69-0.77)Sum scores and ICCs are mean (range).

Abstract
Background:Identification of predictive clinical factors of long-term treatment response in non-radiographic axial spondyloarthritis (nr-axSpA) may contribute to improved management of patients with this chronic disease. Certolizumab pegol (CZP) is currently the only FDA-approved tumour necrosis factor inhibitor (TNFi) for treatment of nr-axSpA.1Objectives:To identify whether any demographic or baseline characteristics of nr-axSpA patients from the C-axSpAnd study2 are predictive of achieving a clinical response after 1 year of CZP treatment.Methods:C-axSpAnd (NCT02552212) was a phase 3, interventional multicentre study including a 52-week double-blind, placebo-controlled period. Full study design is reported elsewhere.2 Multivariate stepwise logistic regression analysis was used to identify predictors of response for the primary efficacy variable (Ankylosing Spondylitis Disease Activity Score – major improvement [ASDAS-MI] at Week 52) and the main secondary efficacy variable (Assessment of SpondyloArthritis international Society 40% [ASAS40] at Week 52) in patients randomised to CZP 200 mg every 2 weeks (Q2W). Predictive factors used in the model included demographic and baseline characteristics, and clinical outcomes at Week 12. A p value ≤0.05 was required for forward selection into the model and p=0.1 for backward elimination from the model. Non-responder imputation was used to account for missing data or values collected after switching to open-label treatment. A sensitivity analysis was conducted to account for patients who had changes in their non-biologic background medication during the 52-week placebo-controlled period.Results:A total of 159/317 patients were randomised to CZP 200 mg Q2W and 158/317 to placebo. Predictive factors identified for Week 52 ASDAS-MI in the CZP-treated patients included being positive for both presence of sacroiliitis on MRI (MRI+) and human leukocyte antigen (HLA)-B27 (HLA-B27+), having a higher Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) at baseline, and having a larger Week 12 improvement in ASDAS (Figure 1A). For ASAS40 response, MRI+/HLA-B27+ was also identified as a predictor of Week 52 response, along with a lower baseline Bath AS Metrology Index (BASMI) and larger Week 12 improvements in Patient Global Assessment of Disease Activity (PtGADA) and AS Quality of Life (ASQoL; Figure 1B). Sensitivity analysis identified the same predictors for ASDAS-MI and ASAS40, with the exception of change from baseline in PtGADA as a predictor of ASAS40. Sensitivity analysis also identified achievement of Week 12 ASAS40 as a predictor of Week 52 ASAS40. In placebo-treated patients, no meaningful predictors of response at Week 52 were identified.Conclusion:Presence of sacroiliitis on MRI and HLA-B27 positivity were identified as consistent predictors of Week 52 response (ASDAS-MI and ASAS40) in nr-axSpA patients treated with CZP. To our knowledge, this is the first report from an interventional 52-week placebo-controlled study in nr-axSpA to identify objective clinical features, particularly the presence of sacroiliac joint inflammation, as being predictive of response.References:[1]Ashrafi M.

Abstract
Background:The ASAS definition of a positive MRI for inflammation in the spine (ASAS-MRIspine+) is intended for classification of patients as having axSpA but is often misused for diagnostic purposes. This is problematic because bone marrow edema (BME) in the spine may occur in 20-40% of those with mechanical back disorders. The ASAS MRI group has generated updated consensus lesion definitions which have been validated on MRI spine images from the ASAS Classification Cohort.Objectives:We aimed to identify quantitative cut-offs based on numbers of vertebral corners that define ASAS-MRIspine+, there being two gold standards: A. majority central reader decision as to the presence of spine MRI findings consistent with axSpA B. rheumatologist expert opinion diagnosis of axSpA.Methods:Eight ASAS-MRI readers recorded MRI lesions in the spine according to recently updated ASAS definitions from 62 cases in an eCRF that comprises global assessment (MRI consistent with axSpA? (yes/no)), and detailed scoring of lesions for all sites in the spine. We calculated sensitivity and specificity for numbers of vertebral corners with BME where a majority of readers (≥5/8) agreed as to the presence of MRI findings consistent with axSpA. We selected cut-offs with ≥95% specificity. These cut-offs were analyzed for their predictive utility for rheumatologist diagnosis of axSpA by calculating positive and negative predictive values (PPV, NPV) and selecting cut-offs with PPV ≥95%. Both criteria were considered requirements for designation of MRI cut-offs defining ASAS-MRIspine+.Results:MRI findings consistent with axSpA were observed by majority read in 8 (20%) of 40 cases diagnosed with axSpA, and 0 (0%) of 19 cases without axSpA. Cut-offs achieving specificity of ≥95% for MRI findings consistent with axSpA were 4 vertebral corners (sensitivity 75%) for all cases, 3 vertebral corners (sensitivity 37.5%) for cases with ≥1 additional location with inflammation, 1 vertebral corner (sensitivity 62.5%) in cases with ≥2 vertebral corner fat lesions (Table 1). All of the above cut-offs also had very high PPV (≥95%) for diagnosis of axSpA in cases diagnosed by the rheumatologist (Table 2).Table 1.Majority readers agree MRI findings consistent with axSpA are present is the gold-standard external referenceMRI cut-offsSensitivity (95%CI)Specificity (95%CI)BME in ≥2 vertebral corners87.5 (47.3 - 99.7)87.0 (75.1 - 94.6)BME in ≥ 3 vertebral corners87.5 (47.3 - 99.7)94.4 (84.6 - 98.8)BME in ≥4 vertebral corners75.0 (34.9 - 96.8)98.2 (90.1 - 100.0)Cases with ≥1 additional non-corner site inflammatory lesionBME in ≥2 vertebral corners37.5 (8.5 - 75.5)94.4 (84.6 - 98.8)BME in ≥3 vertebral corners37.5 (8.5 - 75.5)98.2 (90.1-100.0)Cases with ≥2 vertebral corner fat lesionsBME in ≥1 vertebral corner62.5 (24.5 - 91.5)100.0 (93.4-100.0)BME in ≥2 vertebral corners62.5 (24.5 - 91.5)100.0 (93.4-100.0)Table 2.Predictive values of cut-offs for number of vertebral corners with BME according to the diagnostic ascertainment of the rheumatologistMRI cut-offsSensitivity (95%CI)Specificity (95%CI)PPVNPVMRI findings consistent with axSpA ≥any 2 readers52.5 (36.1 - 68.5)94.7 (74.0 - 99.9)95.5 (75.3 - 99.3)48.6 (40.2 - 57.2)MRI findings consistent with axSpA ≥majority read20.0 (9.1 - 35.6)100.0 (82.4 - 100.0)100.037.3 (33.7 - 40.9)BME in ≥ 4 vertebral corners17.5 (7.3 - 32.8100.0 (82.4 - 100.0)100.036.5 (33.3 - 39.9)Cases with ≥1 additional inflammatory lesionBME in ≥ 3 vertebral corners10.00 (2.8 - 23.7)100.00 (82.4 - 100.0)100.034.5 (32.2 - 36.9)Cases with ≥2 vertebral corner fat lesionsBME in ≥1 vertebral corner12.50 (4.2 - 26.8)100.00 (82.4 - 100.0)100.035.2 (32.6 - 37.9)Conclusion:A cut-off of BME in ≥4 vertebral corners, or ≥3 corners in the setting of additional inflammatory lesions at other locations or corner fat, are primary candidates for defining ASAS-MRIspine+. These cut-offs apply to typical patients referred to a rheumatologist with a high index of suspicion of axSpA and may not be appropriate in other populations.Disclosure of Interests:None declared

Abstract
Background:It is important to understand the potential effect long-term therapy with biologics can have on structural changes in the spine among patients with active radiographic axial spondyloarthritis (r-axSpA, ankylosing spondylitis).Objectives:We examined radiographic progression in the spine among patients with active r-axSpA treated with ixekizumab, an IL-17A antagonist, for 2 years, and potential predictors of spinal radiographic progression.Methods:Patients with active r-axSpA, biologic-naive (COAST-V, NCT02696785) or with prior experience with a maximum of 2 TNF inhibitors (COAST-W, NCT02696798), received 80 mg ixekizumab every 2 or 4 weeks for 2 years (108 weeks, of which 56 weeks were the COAST-Y extension study, NCT03129100). Mean change from baseline of modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) (average score from 2 selected readers, blinded for time order) for patients treated with ixekizumab for 2 years with data at both baseline and year 2 is presented (N=230; 54% of total randomized patients). Non-progression is presented for all patients and subgroups based on TNFi-experience. Predictors were identified in multivariate logistic regression models with stepwise selection criteria of p-value <0.1. All data are observed.Results:At baseline, patients (N=230) were predominately male (82%) with an average age of 43 years, mean symptom duration of 16 years, 52% were TNFi-experienced, mean (SD) ASDAS score was 4.0 (0.7), most were HLA-B27 positive (87%) and 40% had syndesmophytes (identified by both selected readers at the same location). Baseline mSASSS (SD) was 11.0 (16.3) and change from baseline at year 2 of treatment was 0.3 (1.8) (Table 1). The proportion of non-progressors (mSASSS change from baseline <2) over 2 years was 89.6% (total IXE [all patients]), 90.9% (biologic-naive) and 88.3% (TNFi-experienced), and, if defined as mSASSS change from baseline ≤0, 75.7% (total IXE [all patients]), 78.2% (biologic-naive) and 73.3% (TNFi-experienced) (Table 1). Predictors of structural progression at year 2 (mSASSS change >0) were age, baseline syndesmophytes, HLA-B27 status and gender (Table 1). Week 52 inflammation in MRI SPARCC spine was also identified as a predictor for structural progression at year 2 in a separate model for patients from COAST-V where MRI measures were available at baseline and Week 52 (N=109).Conclusion:The majority of patients treated with ixekizumab for 2 years did not show radiographic progression, and the overall mean progression was low. Similar levels of non-progression were observed in biologic-naive patients and patients previously exposed to TNFis. Predictors were generally consistent with previous studies.Table 1.Spinal radiographic changes for patients with active r-axSpA treated with ixekizumab for 2 yearsChange in mSASSS at year 2All patientsaN=230Biologic-naiveN=110TNFi-experiencedN=120 Baseline mSASSS, mean (SD)11.0 (16.3)10.1 (15.5)11.7 (17.0) Change at year 2, mean (SD)0.3 (1.8)0.3 (2.0)0.4 (1.6) Change in total mSASSS <2, n (%)206 (89.6)100 (90.9)106 (88.3) Change in total mSASSS ≤0, n (%)174 (75.7)86 (78.2)88 (73.3)Multivariable logistic regression modelPrediction for change in total mSASSS >0, OR (95% CI), p-valueAll patientsa,bN=228 Age (≥40 years vs. <40 years)2.97 (1.41, 6.28)p=0.004c Baseline syndesmophytesb (yes vs. no)2.31 (1.18, 4.54)p=0.015c Baseline HLA-B27 (positive vs. negative)3.78 (1.04, 13.75)p=0.044c Gender (male vs. female)3.16 (1.01, 9.86)p=0.047c Baseline ASDAS state (>3.5 vs. [2.1, 3.5])2.26 (0.96, 5.34)p=0.063aCombined ixekizumab group of Q2W and Q4W patients with baseline and year-2 mSASSS databIdentified by both selected readers at the same location (2 patients were not evaluable by both readers)cp<0.05Abbreviations: ASDAS=Assessment of Disease Activity, CI=confidence interval, IXE=ixekizumab, mSASSS=modified Stoke Ankylosing Spondylitis Spinal Score, OR=odds ratio, Q2W=every 2 weeks, Q4W=every 4 weeks, SD=standard deviation, TNFi=tumor necrosis factor inhibitorDisclosure of Interests:Désirée van der Heijde Consultant of: AbbVie, Amgen, Astellas, AstraZeneca, Bayer, BMS, Boehringer Ingelheim, Celgene, Cyxone, Daiichi, Eisai, Eli-Lilly, Galapagos, Gilead, Glaxo-Smith-Kline, Janssen, Merck, Novartis, Pfizer, Regeneron, Roche, Sanofi, Takeda, UCB Pharma, Employee of: Director of Imaging Rheumatology bv., Mikkel Østergaard Consultant of: AbbVie, BMS, Boehringer-Ingelheim, Eli Lilly and Company, Janssen, Merck, Pfizer, Roche, UCB, Celgene, Sanofi, Regeneron, Novartis, Grant/research support from: AbbVie, BMS, Merck, UCB, Celgene, Novartis, John D Reveille Paid instructor for: UCB, Eli Lilly and Company, Consultant of: UCB, Eli Lilly and Company, Pfizer, Novartis, Grant/research support from: Janssen, Eli Lilly and Company, Xenofon Baraliakos Speakers bureau: Abbvie, BMS, Lilly, Janssen, Novartis, MSD, Pfizer, Galapagos, Gilead, UCB, Paid instructor for: Abbvie, BMS, Lilly, Janssen, Novartis, MSD, Pfizer, Galapagos, Gilead, UCB, Consultant of: Abbvie, BMS, Lilly, Janssen, Novartis, MSD, Pfizer, Galapagos, Gilead, UCB, Andris Kronbergs Shareholder of: Eli Lilly and Company, Employee of: Eli Lilly and Company, David Sandoval Shareholder of: Eli Lilly and Company, Employee of: Eli Lilly and Company, Xiaoqi Li Shareholder of: Eli Lilly and Company, Employee of: Eli Lilly and Company, Hilde Carlier Shareholder of: Eli Lilly and Company, Employee of: Eli Lilly and Company, David Adams Shareholder of: Eli Lilly and Company, Employee of: Eli Lilly and Company, Walter P Maksymowych Speakers bureau: Abbvie, Janssen, Novartis, Pfizer, UCB, Consultant of: Abbvie, Boehringer, BMS, Eli Lilly and Company, Novartis, Pfizer, UCB, Grant/research support from: Abbvie, Novartis, Pfizer

Abstract
Background:Axial spondyloarthritis (axSpA) presents diagnostic challenges incurring a delay of up to a decade and relies considerably on radiographic and MRI evidence of sacroiliitis which has led to the development of classification criteria which also rely on imaging. However, it has been suggested that such criteria may not be appropriate for axSpA patients presenting with other forms of SpA, especially psoriatic, because imaging features may vary in frequency and/or may be atypical. This hypothesis has never been tested in a prospective inception cohort of patients presenting with undiagnosed back pain.Objectives:We aimed to compare the spectrum of radiographic and MRI abnormalities in the sacroiliac joint (SIJ) of an inception cohort of patients presenting with undiagnosed back pain and psoriasis, iritis, and colitis.Methods:We used data from the prospective multicenter Screening for Axial Spondyloarthritis in Psoriasis, Iritis, and Colitis (SASPIC) Study, which is aimed at early detection of axial SpA in patients referred by the respective specialist after first presenting with these disorders. Consecutive patients ≤45 years of age with ≥3 months undiagnosed back pain with any one of psoriasis, AAU, or colitis undergo routine clinical evaluation by a rheumatologist for axial SpA followed by imaging. In SASPIC I, MRI evaluation of the SIJ was ordered per rheumatologist decision. In SASPIC II, MRI evaluation was ordered for all patients. Radiographs and MRI scans were assessed by two central readers and comparisons of the three groups were based on concordant assessments of imaging features. Evaluation of MRI scans included both global assessment for presence/absence of axSpA with confidence scale (-10 to +10), active and structural lesions typical of axSpA per recent ASAS definitions, and granular assessment of individual lesions according to SIJ quadrants and halves in consecutive semicoronal slices through the SIJ. Groups were compared by ANOVA and the chi-square test.Results:A total of 240 patients were recruited, 143 from SASPIC I and 97 from SASPIC II, 101 (42.1%) being diagnosed with axSpA (65.3% male, mean age 34.4 years, mean symptom duration 8.7 years, B27 positive 55.4%). Mean age of colitis (N=101), psoriasis (N=61), iritis (N=78) patients were 33.4, 36.6, 34.3 years, respectively, mean symptom duration was 6.8, 7.2, 9.4 years, respectively, and % males were 45.5%, 52.5%, 51.3%, respectively. There were no significant group differences for unilateral versus bilateral radiographic sacroiliitis and no significant differences in the frequencies, type, or distribution of MRI lesions (Table 1).Conclusion:Data from the SASPIC prospective inception cohort does not support the view that imaging of the SIJ differs in psoriatic axSpA, which appears similar to axSpA associated with iritis or colitis.

Abstract
Background:Upadacitinib (UPA) was efficacious and well tolerated vs placebo (PBO) during the first 14 weeks (wks) of the phase 2/3 SELECT-AXIS 1 study in patients (pts) with active ankylosing spondylitis (AS) who had an inadequate response to NSAIDs.1Objectives:To report efficacy and safety of UPA through 1 year in the SELECT-AXIS 1 study.Methods:In SELECT-AXIS 1 (NCT03178487) pts were randomized 1:1 to UPA 15 mg once daily (QD) or PBO; at wk 14, pts continued in the 90-wk open-label extension and received UPA 15 mg QD; reported here are data up to wk 64. The study enrolled pts (≥18 y) with active AS (defined as BASDAI ≥4 and pt assessment of back pain ≥4 [numeric rating scale, 0–10] at screening and baseline [BL]) who had inadequate response to ≥2 NSAIDs or intolerance to or contraindication for NSAIDs and were biologic DMARD naive. Efficacy assessments included percentage of pts with Assessment of SpondyloArthritis international Society (ASAS) 20/40 response, ASAS partial remission, BASDAI50, AS Disease Activity Score (ASDAS) and change from BL in ASDAS and BASFI. Data are reported as observed and by using non-responder imputation (NRI). Treatment-emergent adverse events (TEAEs) were reported as events per 100 patient-years (PY) up to January 31, 2020.Results:Of 187 pts, 178 pts (each n=89 for UPA and PBO arms) completed wk 14 on study drug and entered the open-label extension; 160 pts completed wk 64. Efficacy was maintained or continued to improve throughout the study in the continuous UPA group: 85% (95% CI, 77%–93%) of pts achieved ASAS40 at wk 64 in the as-observed analysis and 72% (63%–81%) in the NRI analysis (Figure). Pts who switched from PBO to UPA at wk 14 showed similar speed of onset and magnitude of response vs pts initially randomized to UPA: 81% (95% CI, 72%–89%) in the as-observed analysis and 70% (61%–80%) in the NRI analysis achieved ASAS40 at wk 64 (Figure). Similar results were observed for other efficacy endpoints (Figure). Among all 182 pts receiving UPA, 618 AEs were reported. AEs leading to discontinuation and serious AEs were low (Table). No serious infections, active tuberculosis, venous thromboembolic events, gastrointestinal perforation, major adverse cardiovascular events, renal dysfunction, or deaths were reported.Table 1.TEAEs per 100 PYsEvents/(E/100 PY)UPA 15 mg QDN=182 (237.6 PY)Any AE618 (260.1)Serious AE14 (5.9)AE leading to discontinuation15 (6.3)Infections205 (86.3) Opportunistic infection*2 (0.8) Herpes zoster†5 (2.1)Creatine phosphokinase elevation‡28 (11.8)Hepatic disorder§24 (10.1)Neutropenia||7 (2.9)Anemia||3 (1.3)Lymphopenia||2 (0.8)Malignancy¶1 (0.4)Death0AE, adverse event; PY, patient-year; QD, once daily; TEAE, treatment-emergent AE; UPA, upadacitinib.*Two non-serious events of esophageal candidiasis in the same patient.†Five events in 4 patients; all non-serious and limited to 1 dermatome.‡All events were non-serious and none led to study drug discontinuation; majority were asymptomatic.§Majority based on asymptomatic alanine aminotransferase/aspartate aminotransferase elevations; all were non-serious and none led to study drug discontinuation.||All events were non-serious and none led to study drug discontinuation.¶Squamous cell carcinoma of tongue in 61-year-old male former smoker; no reasonable possibility to be study drug related per investigator.Conclusion:UPA 15 mg QD showed sustained and consistent efficacy over 1 year.

Abstract
Background:Osteoarthritis (OA) is the commonest disease affecting hip joints and has high prevalence across various age groups [1,2]. Effusion is a hallmark of OA and could represent a potential target for therapy [3–5]. Positive correlations of effusion to clinical outcomes are not well established, partly due to variability in manual assessment. Voxel-based volume quantification could reduce this variability [6].Objectives:We examine the inter-observer agreement of manual assessment of voxel-based effusion volume from coronal STIR MRI sequences at two time points and examine the feasibility of using Artificial Intelligence (AI) for standalone volume assessment.Methods:Our algorithm is based on Mask R-CNN [7] and was trained on labeled effusion regions in MRI slices from 68 patients with hip osteoarthritis. For validation, 2 human readers measured effusion from MRI STIR sequences of 25 patients at baseline and at 8 weeks follow-up. AI was used to measure effusion volume as an independent reader. Agreement between human readers and AI was assessed using absolute difference in volume (DV), Coefficients of Variation (CoV) and intraclass correlation coefficient (ICC).Results:Effusion regions detected by AI closely correlated with manual segmentation (Figure 1) for all samples. Differences in volumes measured by each pair of readers are summarized in Table 1. Agreement was excellent between human readers (ICC=0.99) and for each reader vs AI (ICC = 0.85-0.87).Figure 1.Mask overlays of regions of joint fluid detected by human readers (green, column 2) and AI (red, column 3) from 3 different patients. Raw MRI images are shown in column 1.Table 1.Comparison of volumes measured in cubic millimeters and agreement between each pair of readers (with AI as the 3rd reader)Volumes measured by readersAgreement between reader pairsReaderOverall VolumeMean ± Standard DeviationReader PairDifference in VolumeMean ± Standard DeviationCoVICCReader 16943 ± 5845Reader 1-21127 ± 9000.210.99 [0.98, 1.0]Reader 27638 ± 5619Reader 1-AI3311 ±16430.350.87 [0.7, 0.94]AI11014 ± 4454Reader 2-AI4151 ± 49860.270.85 [0.66,0.94]Conclusion:Initial results of automatic effusion measurement using AI show high agreement with human experts.

Abstract
Background:Patients with a diagnosis of Spondyloarthritis (SpA) and Psoriatic Arthritis (PsA) may have predominant axial or peripheral symptoms, and the frequency and distribution of these symptoms may determine the clinical diagnosis by the rheumatologist (“clinical clusters”). Clustering analysis represents an unsupervised exploratory analysis which tries to identify homogeneous groups of cases (“statistical clusters”) without prior information about the membership for any of the cases.Objectives:To identify “statistical clusters” of peripheral involvement according to the specific location of these symptoms in the whole spectrum of SpA and PsA (without prior information about the diagnosis of the patients), and to evaluate whether these “statistical clusters” are in agreement with the “clinical clusters”.Methods:Cross-sectional and multicentre study with 24 participating countries. Consecutive patients considered by their treating rheumatologist as suffering from either PsA, axial SpA (axSpA) or peripheral SpA (pSpA) were enrolled. Four different cluster analyses were conducted: the first one using information about the specific location from all the peripheral musculoskeletal manifestations (i.e., peripheral arthritis, enthesitis and dactylitis), and thereafter a cluster analysis for each peripheral manifestation individually. Multiple correspondence analyses and k-means clustering methods were used. Distribution of peripheral manifestations and clinical characteristics were compared across the different clusters.Results:4465 patients were included in the analysis. Two clusters were found with regard to the location of all the peripheral manifestations (Fig. 1). Cluster 1 showed a low prevalence of peripheral manifestations in comparison with cluster 2; however, when peripheral involvement appeared in cluster 1, this was mostly represented by arthritis of hip, knee and ankle, as well as enthesitis of the heel. Patients from cluster 1 showed a higher prevalence of males (63% vs 44%), HLA-B27 positivity (69% vs 38%) and axial involvement (80% vs 52%), as well as more frequent diagnosis of axSpA (66% vs 21%) and more frequently fulfilling the ASAS axSpA criteria (69% vs. 41%). Patients from cluster 2 showed a higher prevalence of psoriasis (63% vs 25%), a more frequent diagnosis of PsA (61% vs 19%), and they fulfilled more frequently the peripheral ASAS (26% vs 11%) and the CASPAR criteria (57% vs 19%).Figure 1.Distribution of the peripheral involvement across clustersThree clusters were found with regard to the location of the peripheral arthritis. Clusters 2 and 3 showed a high prevalence of peripheral joint disease, although this was located more predominantly in the lower limbs in cluster 2, and in the upper limbs in cluster 3. Cluster 1 showed a higher prevalence of males, HLA-B27 positivity, axial involvement, a lower presence of psoriasis, a more frequent diagnosis of axSpA and fulfilling the ASAS axSpA criteria in comparison with clusters 2 and 3, respectively. Clusters 2 and 3 showed a higher prevalence of enthesitis and dactylitis in comparison with cluster 1, a more frequent diagnosis of PsA and fulfillment of the CASPAR criteria.Information about the location of enthesitis exhibited three groups: cluster 1 showed a very low prevalence of enthesitis, while cluster 2 and 3 showed a high prevalence of enthesitis, with a predominant involvement of axial enthesis in cluster 2 and peripheral enthesitis in cluster 3.Finally, the analysis of dactylitis also exhibited three clusters that showed a very low prevalence of dactylitis, predominantly toes and predominantly fingers involvement, respectively.Conclusion:These results suggest the presence of heterogeneous patterns of peripheral involvement in SpA and PsA patients without clearly defined groups, confirming the clear overlap of these peripheral manifestations across the different underlying diagnoses.Acknowledgements:This study was conducted under the umbrella of ASAS with unrestricted grant of Abbvie, Pfizer, Lilly, Novartis, UCB, Janssen and Merck.Disclosure of Interests:None declared

Abstract
Background:Filgotinib, an oral selective Janus kinase (JAK) 1 inhibitor, reduced disease activity and improved symptoms and inflammation of the sacroiliac joint (SIJ) and spine in patients with active axial ankylosing spondylitis (AxSpA) in the Phase 2 TORTUGA trial (NCT03117270).1The effects of JAK inhibitors on structural lesions in active AxSpA are unknown and optimal methods for image analysis of structural disease progression are not established.Objectives:The aim of this post hoc analysis was to evaluate the effects of filgotinib on magnetic resonance imaging (MRI) measures of structural changes in the SIJ in patients from the TORTUGA trial, as assessed by Spondyloarthritis Research Consortium of Canada (SPARCC) SIJ Structural Scores (SSS).Methods:TORTUGA was a multicenter, double-blind, randomized trial of 116 patients with active AxSpA treated with filgotinib 200 mg (n=58) or placebo (n=58) once daily for 12 weeks. MRI was conducted at baseline and Week 12 (or early discontinuation visit). MRIs were re-evaluated post hoc by two independent experts (blinded to time point and assigned treatment) to determine SPARCC SSS; inter-reader discrepancies were resolved by an independent adjudicator. Observed changes from baseline were evaluated using analysis of covariance with factors for treatment, baseline value, and randomization stratification. Least-squares mean changes from baseline and between-group differences with 95% confidence intervals were calculated.Results:MRI scans from 87 patients with an evaluable MRI at baseline and Week 12 (or early termination visit) were re-evaluated (48 filgotinib, 39 placebo).

Abstract
Background:Clinicians rely on the elicitation of features of inflammatory back pain (IBP) for diagnosis of axial spondyloarthritis (axSpA) but the utility of IBP criteria in patients presenting with extra-articular features of axSpA remains unclear. Assessment of utility should include not only rheumatologist diagnosis as benchmark but imaging to address the circularity between elicitation of IBP and clinical diagnosis.Objectives:To assess the diagnostic utility of all criteria for IBP in patients with psoriasis, iritis, or colitis and undiagnosed back pain using the rheumatologist diagnosis and imaging as benchmarks.Methods:Consecutive patients (n=246) with undiagnosed back pain ≤45 years of age, ≥3 months, with any one of psoriasis (n=46), acute anterior uveitis (AAU)(n=73), or colitis (n=127) had diagnostic evaluation by a rheumatologist. Majority central reader assessment of MRI indicative of axSpA and diagnosis by the rheumatologist were external standards for testing the utility of these IBP criteria: ASAS, Berlin, Calin, rheumatologist global for IBP >5 (0-10 scale).Results:AxSpA was diagnosed in 44.4%, 61.6%, and 41.8% of patients with psoriasis, iritis, and IBD, respectively. Diagnostic utility for all IBP criteria was comparably poor (Table 1). MRI was indicative of axSpA in 21.2%, 43.5%, and 19.7% of patients with psoriasis, iritis, and IBD. The utility of the IBP criteria was even worse using MRI as the external reference (Table 2), especially in patients with psoriasis. Only 14% of psoriasis patients with a positive MRI reported “improvement with exercise but not rest” as compared to 70% and 62% of patients with iritis and IBD, respectively.Table 1.Rheumatologist diagnosis as external reference.SensitivitySpecificityLR+LR-PsoriasisASAS IBP65.00%52.00%1.350.67Berlin IBP80.00%36.00%1.250.56Calin IBP80.00%28.00%1.110.71All 3 criteria sets60.00%56.00%1.360.71IBP global >585.00%36.00%1.330.42AAUASAS IBP84.44%42.86%1.480.36Berlin IBP80.00%57.14%1.870.35Calin IBP93.33%17.86%1.140.37All 3 criteria sets77.78%60.71%1.980.37IBP global >586.67%57.14%2.020.23IBDASAS IBP78.43%45.07%1.430.48Berlin IBP82.35%52.11%1.720.34Calin IBP84.31%19.72%1.050.80All 3 criteria sets70.59%57.75%1.670.51IBP global >580.39%66.20%2.380.30Table 2.Central assessment that MRI is indicative of axSpA as external reference.SensitivitySpecificityLR+LR-PsoriasisASAS IBP28.57%38.46%0.461.86Berlin IBP42.86%15.38%0.513.71Calin IBP71.43%23.08%0.931.24All 3 criteria sets14.29%42.31%0.252.03IBP global >585.71%23.08%1.110.62AAUASAS IBP75.00%26.92%1.030.93Berlin IBP70.00%38.46%1.140.78Calin IBP90.00%15.38%1.060.65All 3 criteria sets65.00%38.46%1.060.91IBP global >575.00%38.46%1.220.65IBDASAS IBP92.31%37.74%1.480.20Berlin IBP76.92%39.62%1.270.58Calin IBP92.31%16.98%1.110.45All 3 criteria sets76.92%45.28%1.410.51IBP global >592.31%47.17%1.750.16Conclusion:All IBP criteria have poor diagnostic utility for diagnosis of axSpA, especially in patients with psoriasis.

Abstract
Background:Ankylosing spondylitis (AS) is a chronic, immune-mediated disease characterized by inflammation of the sacroiliac joints and spine, and a young age of onset of 20–40 years. In the recent TORTUGA study, filgotinib (FIL), an oral, selective Janus kinase 1 (JAK1) inhibitor, significantly reduced AS disease activity compared with placebo (PBO).1Selective JAK1 inhibition by FIL has the potential to simultaneously block multiple inflammatory pathways, thus we analyzed biomarker concentrations in serum samples from TORTUGA.Objectives:To evaluate the impact of selective JAK1 inhibition with FIL on circulating disease associated biomarkers in adult patients with active AS enrolled in the TORTUGA study.Methods:TORTUGA (Clinicaltrials.gov identifierNCT03117270) was a 12-week, randomized, double-blind, placebo-controlled, phase 2 study. Patients were randomized 1:1 to FIL 200 mg (n=58) or PBO (n=58) once-daily. Serum samples (FIL n=56, PBO n=53) were collected at baseline (BL) and weeks 1, 4 and 12, and analyzed using the Meso Scale Discovery immunoassay platform (Meso Scale Diagnostics, Rockville, MD, USA) to evaluate 135 biomarkers. Biomarker concentration changes from BL were analyzed on paired patient data and reported for weeks 1, 4 and 12, and clustering analysis was performed. Correlation between the 135 biomarkers and selected clinical scores at BL was assessed by Spearman rank correlation analysis.Results:FIL treatment produced significant reductions in serum concentrations of multiple biomarkers associated with AS disease activity. Five clusters of biomarker response were identified based on the kinetics and magnitude of percent changes from BL. These clusters also represented discrete biological functions: cluster 1 (rapid, strong >50% decrease in all three time points) included systemic inflammation biomarkers eg, CRP, SAA; cluster 2 (>20% decrease in at least one time point) included immune cell biomarkers eg, MIP3B, IL12p40; cluster 3 (<20% decrease in all three time points) included cellular adhesion biomarkers eg, ICAM-1, VCAM-1; cluster 4 (delayed decrease) included matrix remodelling biomarkers eg, MMP1, TIMP1; and cluster 5 included biomarkers that exhibited a gradual increase in serum concentration with FIL treatment.Spearman rank correlation analyses showed that at BL, the systemic inflammation biomarkers CRP and SAA, as well as a number of biomarkers including ICAM-1 and MMP3, were positively correlated with BL AS disease activity score (ASDAS); conversely, only a few biomarkers showed a negative correlation with BL ASDAS, the cytokine receptor FLT3 and the chemotactic cytokine fractalkine (FRACTAL).Conclusion:In patients with active AS, FIL treatment significantly decreased levels of circulating biomarkers associated with active AS disease, including proinflammatory cytokines and chemokines, cell adhesion molecules, and markers of matrix remodelling. Clustering analysis revealed early and late biomarker changes associated with disease. These data are consistent with reduced AS disease activity in TORTUGA and suggest that FIL treatment leads to a rapid and sustained reduction of inflammation in AS.References:[1]van der Heijde Det al.

Abstract
Background:The ASAS classification criteria for axial spondyloarthritis (axSpA) have overall sensitivity/specificity of 82.9%/84.4% but component imaging and clinical arms differ in performance (66.2%/97.3% and 56.6%/83.3%, respectively)1.Objectives:We aimed to demonstrate that a data-driven elimination of SpA clinical features that were non-discriminatory in comparisons of patients diagnosed with and without axSpA in a prospective cohort of patients with undiagnosed back pain could enhance the performance of the criteria.Methods:We used data from the prospective multicenter Screening for Axial Spondyloarthritis in Psoriasis, Iritis, and Colitis (SASPIC) Study. Consecutive patients ≤45 years of age with ≥3 months undiagnosed back pain with any one of psoriasis, AAU, or colitis undergo routine diagnostic evaluation by a rheumatologist for axial SpA, including imaging assessed by central readers. Univariable and multivariable logistic regression analysis was performed to determine which clinical SpA features were/were not discriminatory for the final diagnosis of axSpA. We then compared the sensitivity and specificity of the ASAS criteria with and without these features.Results:A total of 246 patients were recruited, 47.6% being diagnosed with axSpA (61.5% male, age 33.7 years, symptom duration 7.6 years, B27 positive 52.1%). The following clinical SpA features were non-discriminatory between axSpA/not axSpA: NSAID response, family history of SpA, heel enthesitis, peripheral arthritis, dactylitis. Specificity of the clinical arm and the overall criteria increased from 82.2% to 86.8% without impacting sensitivity. This effect was particularly noteworthy in patients with lower degree of symptomatology (back pain severity <5/10, specificity increases from 76.7% to 90.7%), short symptom duration (<5 years, specificity increases from 78% to 84.7%), and in females (specificity increases from 80.6% to 86.1%).Conclusion:In a prospective cohort with a high pre-test probability of axSpA certain clinical SpA features were not helpful in discriminating a diagnosis of SpA from not-SpA. Deletion of these features from the list of SpA features used in the ASAS classification criteria enhanced the performance of the criteria, especially in female patients and those with early disease.References:[1]Rudwaleit et al.

Abstract
Background:Patients presenting with back pain and psoriasis, iritis, or colitis, represent a high-risk population for the presence of axial spondyloarthritis (axSpA). The Dublin Evaluation Tool (DUET)1, the Berlin algorithm2, and the ASAS modification of this algorithm3are recommended referral strategies aimed at early diagnosis of axSpA. DUET was developed for patients presenting with AAU. Validation of these algorithms in inception cohorts is limited.Objectives:1. To assess the performance of referral algorithms for diagnosis of axSpA when tested against the final local rheumatologist diagnosis in an inception cohort of patients presenting with undiagnosed back pain and extra-articular manifestations. 2. To determine whether different criteria for inflammatory back pain (IBP) impact the performance of the algorithms.Methods:The multicenter Screening for Axial Spondyloarthritis in Psoriasis, Iritis, and Colitis (SASPIC) Study at 11 sites is aimed at early detection of axial SpA in patients presenting with undiagnosed back pain to the rheumatologist. Consecutive patients ≤45 years of age with ≥3 months undiagnosed back pain with any one of psoriasis, acute anterior uveitis (AAU), or colitis diagnosed by the relevant specialist undergo routine clinical evaluation by a rheumatologist for axial SpA. The rheumatologist determines the presence or absence of axial SpA at 3 consecutive stages: 1. After the clinical evaluation; 2. After the results of labs (B27, CRP) and radiography; 3. After the results of MRI evaluation. Final diagnosis by the rheumatologist was used as external standard to test the performance of the algorithms. We tested the following criteria for IBP in the algorithm: ASAS, Berlin, rheumatologist global for likelihood of IBP >5 (0-10 scale), and DUET algorithm in AAU patients.Results:A total of 246 patients were recruited, 73 presented with iritis, 46 with psoriasis, and 127 with colitis, 47.6% were diagnosed with axSpA. The diagnosis of axSpA was established in 45.7%, 61.6%, and 40.2% of patients with psoriasis, AAU, and IBD, respectively. The performance of the ASAS-modification of the Berlin algorithm was superior to the original algorithm as reported previously3, primarily for enhanced sensitivity, and this was observed irrespective of the criteria used to define IBP (Table 1). Conversely, the performance of the Duet algorithm in the subset of patients with AAU was substantially worse than previously reported1.Conclusion:The ASAS modification of the Berlin algorithm is the preferred referral strategy for patients presenting with undiagnosed back pain to the rheumatologist.References:[1]Haroon M, et al.

Abstract
Background:Biosimilar etanercept (ETA-B) was recently introduced in Canada but real-world data descriptions of drug persistence (and comparisons with the originator product, ETA-O) are still scarce.Objectives:To describe and compare persistence of ETA-B and ETA-O in RA.Methods:We used data from four ongoing, prospective cohorts in Canada: the Canadian Early Arthritis Cohort (CATCH), the Rheumatoid Arthritis Pharmacovigilance Program and Outcomes Research in Therapeutics (RAPPORT), the Early Undifferentiated Polyarthritis (EUPA) cohort, and the RHUMADATA® registry. We studied biologic-naïve and biologic-experienced RA adults initiating ETA-B or ETA-O between Jan. 2015 and Oct. 2019. Switchers from ETA-O to ETA-B (or vice-versa) were included. We assessed persistence of therapy in the first 12 or 24 months, measured as time from therapy initiation (time zero) to discontinuation. Individuals switching between products could contribute further person-time to the new exposure category. Multivariable Cox regression models were performed with each cohort dataset separately, following a common protocol. Model variables included age, sex, comorbidity, past biologic use, and disease duration. After testing for between-study heterogeneity (Higgin’s I2), cohort-estimated hazard ratios (HR) were pooled using random effects meta-analysis.Results:We identified 262 episodes of etanercept use (118 ETA-B and 144 ETA-O) from 250 RA patients. Sex, age, and other baseline characteristics across the four cohorts are shown in Table 1. Across cohorts, there was considerable variation in RA duration at the time of initiating ETA-B or ETA-O. In the pooled analysis, the HR for discontinuation at 24 months comparing ETA-B to ETA-O was 0.51 (95% confidence interval, CI: 0.26-0.98). The pooled analysis for therapy discontinuation at 12 months adjusted HR in this analysis was 0.82 (95% CI: 0.42-1.60).Table 1.Characteristics of studied patients according to their treatment episodes, biosimilar etanercept (ETA-B) or bio-originator etanercept (ETA-O).CharacteristicEUPARAPPORTRHUMADATACATCHETA-BETA-OETA-BETA-OETA-BETA-OETA-BETA-ON=19N=27N=32N=30N=39N=52N=28N=35Female sex, (%)12 (63)18 (67)20 (63)22 (73)28 (72)38 (73)20 (71)27 (77)Mean age in years1, SD59 (13)59 (16)51 (15)54 (15)59 (15)54 (15)55 (12)51 (13)Current smoker, (%)3 (17)5 (21)9 (32)5 (19)8 (21)9 (17)5 (18)8 (23)Cardiovascular disease, (%)0 (0)0 (0)1 (3.1)1 (3.3)8 (21)2 (4)NANADiabetes, (%)0 (0)0 (0)4 (13)1 (3)2 (5)3 (6)NANAHypertension, (%)NANA5 (16)4 (13)14 (36)22 (42)NANARA duration in years1, SD2 (3)7 (13)8 (6)12 (15)12 (12)9 (9)4 (4)3 (3)DAS-2812 (NA)4 (2.8)6 (1)6 (1)4 (2)4 (1)4.0 (2)4 (2)SDAI113 (14)44 (5)NANA21 (15)23 (8)23 (14)25 (16)Past oral steroids, N(%)Past biologic, N(%)15 (79)17 (63)6 (19)4 (13)29 (74)31 (60)9 (32)13 (37)Past non-biologic DMARD,8 (42)6 (22)2 (6)0 (0)21 (54)20 (38)19 (68)21 (60)N(%)19 (100)27 (100)30 (94)26 (87)39 (100)52(100)25 (89)33 (94)1At time zero or at the closest date before time zero.

Abstract
Background:Active MRI lesions typical of axial spondyloarthritis (axSpA) were reported in 61.6% and 2.2% of axSpA and not-axSpA patients, respectively, from the ASAS classification cohort (ASAS-CC)1. Discrepancy between local and central reader evaluation of MRI scans could result in differences in numbers of patients fulfilling the imaging arm of the ASAS classification criteria. But final classification may not be impacted if discrepant patients still fulfill the clinical arm.Objectives:We aimed to assess the impact of reader discrepancy in detection of active MRI lesions on the number of patients classified as having axSpA in patients recruited to the ASAS-CC.Methods:MRI images of the sacroiliac joints (SIJs) were available from 252 cases in the ASAS-CC, and these also had clinical and radiographic data. Seven central readers from the ASAS-MRI group recorded MRI lesions in an eCRF that included active lesions typical of axSpA in the SIJ (MRI-active) that was worded exactly the same as in the original ASAS-CC eCRF permitting comparisons between central and local site readers. Active lesions were deemed to be present according to majority agreement (≥4/7) of central readers and also any 2 central readers. We calculated the number of patients that were classified differently after central evaluation for overall fulfilment of the ASAS criteria and for the imaging arm.Results:Discordance between central and local readers for detection of MRI-active was recorded in 45(17.8%) and 47(18.2%) of cases according to 2-reader and majority (≥4/7) central reader data, respectively (kappa (95%CI) of 0.64 (0.54-0.73) and 0.62 (0.53-0.72). With central reading as external standard the false-positive rate for active lesions was 26.9%% and 32.2% (‘local overcall’) for 2-reader and majority reader data, respectively. There were 159(63.1%) patients who fulfilled the ASAS axSpA criteria based on local-reading, and 148(58.7%) and 143(56.7%) patients based on 2-reader and majority central-reading, respectively (Table). When fulfillment of the imaging arm was the primary consideration (irrespective of the clinical arm), 126 (50%) patients fulfilled the criteria based on local-reading, and 111 (44%) and 102 (40.5%) patients based on 2-reader and majority central-reading, respectively.Conclusion:Despite substantial overcall for positive MRI SIJ inflammation by local readers, the number of patients classified as having axSpA did not change substantially. This is due to the alternate mechanism for classification through the clinical arm.References:[1]Rudwaleit et al. Ann Rheum Dis 2009;68: 777-83Impact of Central Vs.

Abstract
Background:There is lack of international consensus as to what defines a structural lesion on MRI of the sacroiliac joints (SIJ) typical of axial spondyloarthritis (axSpA). The ASAS MRI group has generated updated consensus lesion definitions that describe each of the MRI lesions in the SIJ1. These definitions have been evaluated by 7 readers from the ASAS-MRI group on MRI images from the ASAS Classification Cohort.Objectives:We aimed to identify quantitative cut-offs based on numbers of slices and SIJ quadrants that define a positive MRI for structural lesions typical of axSpA, the gold standard being majority central reader decision as to the presence of a structural lesion typical of axSpA with high confidence.Methods:MRI structural lesions meeting ASAS definitions were recorded in an eCRF that comprises global assessment (structural lesion typical of axSpA present/absent and degree of confidence (-4 (absent) to +4 (present)), and detailed scoring of lesions per SIJ quadrant. Detailed scoring was based only on assessment of DICOM images (n =148). We calculated sensitivity and specificity for numbers of SIJ quadrants and consecutive slices with erosion, sclerosis, and fat lesions where a majority of readers (≥4/7) agreed as to the presence of a structural lesion typical of axSpA with high confidence (≥ +3). We tested candidate lesion definitions for predictive diagnostic utility in cases assessed after 4.4 years of follow up by the local rheumatologist.Results:Structural lesions typical of axSpA were observed by majority read in 33 (32.4%) of 102 cases diagnosed with axSpA, and 3 (6.8%) of 44 cases without axSpA and 29 cases were assigned a high degree of confidence (≥ +3) by a majority of readers. Cut-offs achieving specificity of 95% were erosion in ≥2 consecutive slices (sensitivity 83%), erosion ≥3 SIJ quadrants (sensitivity 90%), and fat lesion (≥1cm horizontal depth) in ≥1 SIJ quadrant (sensitivity 59%) (Table). These had very high positive predictive values (>95%) for diagnosis of axSpA in cases diagnosed by the rheumatologist after 4.4 years follow up.Conclusion:ASAS-defined erosion in ≥2 consecutive slices or in ≥3 SIJ quadrants and ASAS-defined fat lesion with depth >1cm in ≥1 SIJ quadrant are high priority candidates for defining an MRI structural lesion typical of axSpA. This will require similar assessment in additional axSpA cohorts.References:[1]Maksymowych et al.

Abstract
Background:Classification of axial spondyloarthritis (axSpA) is based on either an imaging or clinical arm. Radiographic or MRI evidence of sacroiliitis can be applied for the imaging arm. However, it is well-established that reliability and sensitivity of radiographic sacroiliitis is inadequate.Objectives:To assess the impact of replacing radiographic sacroiliitis with MRI structural lesions (MRI-S) typical of axSpA on the number of patients classified as having axSpA in patients with undiagnosed back pain recruited to the ASAS Classification Cohort (ASAS-CC).Methods:MRI images of the sacroiliac joint (SIJ) were available from 217 cases in the ASAS-CC, which also had clinical, laboratory, and radiographic data. Seven central readers from the ASAS-MRI group recorded MRI lesions in an eCRF that included active (MRI-A) and structural (MRI-S) lesions typical of axSpA. MRI-A was deemed to be present according to majority agreement (≥4/7) of central readers. MRI-S was deemed to be present according to the majority (majority reader MRI-S) and also according to at least 2 central readers (≥2-reader MRI-S). We calculated the number of patients that were classified differently after replacement of radiographs by MRI-S for overall fulfillment of the ASAS criteria and for the imaging arm.Results:In total, 119 (54.8%) cases fulfilled the axSpA criteria based on local reading of radiographic sacroiliitis and central reading of active inflammation on MRI. This changed to 125 (57.6%) and 118 (54.4%) of cases after replacement of radiographic sacroiliitis by ≥2-reader and majority reader MRI-S, respectively (Table). A total of 13 (6.0%) and 7 (3.2%) cases who were classified as not having axSpA were re-classified as having axSpA after replacing radiographic sacroiliitis with ≥2-reader and majority reader MRI-S, respectively. Conversely, 7 (3.2%) and 8 (3.7%) cases were re-classified as not having axSpA after substitution by ≥2-reader and majority reader MRI-S, respectively. When fulfillment of the imaging arm was the primary consideration (irrespective of the clinical arm), the number of patients reclassified from not axSpA to axSpA was 25 (11.5%) by ≥2-reader and 13 (6.0%) by majority reader MRI-S, while 8 (3.7%) and 11 (5.1%) were reclassified from axSpA to not axSpA.Conclusion:The number of patients classified as having axSpA does not change substantially when MRI-S replaces radiographic sacroiliitis. However, it remains possible that MRI structural lesions can influence the final diagnosis, the gold standard for assessment of the performance of the ASAS criteria.Impact of Replacement of Radiographic Sacroilitis by MRI Structural Lesions on SpA Classification in cases with all clinical, radiographic, and central and local MRI inflammation data available (n=217)MRI assessment usedSpA Classification=Yes N(%)SpA Classification=No N(%)Imaging Arm SpA Classification=Yes N(%)Imaging Arm SpA Classification=No N(%)Radiographic Sacroiliitis + Majority Central Reader MRI Inflammation Positive119 (54.8%)97 (44.7%)83(38.2%)134 (61.8%)Replace Radiographic Sacroiliitis with ≥2 Central Reader MRI Structural Positive125 (57.6%)92 (42.4%)100 (46.1%)117 (53.9%)Replace Radiographic Sacroiliitis with Majority Central Reader MRI Structural Positive118 (54.4%)99 (45.6%)85 (39.2%)132 (60.8%)Disclosure of Interests:Walter P.

Abstract
Background:Diagnosis of axial spondyloarthritis (axSpA) is challenging because of absent physical findings in early disease and the limited diagnostic performance of laboratory markers. Considerable reliance is placed on imaging of the sacroiliac joints (SIJ) but specialty training is primarily focused on interpretation of plain radiographic abnormalities.Objectives:We aimed to identify what might be the primary unmet educational needs of rheumatologists completing fellowship training by using clinical and imaging data from an inception cohort of patients presenting with undiagnosed back pain. We hypothesized that concordance would increase after imaging is reviewed after the clinical data.Methods:The diagnosis of axSpA was compared between local rheumatologists, axSpA experts and pF using clinical and imaging data from the multicenter Screening for Axial Spondyloarthritis in Psoriasis, Iritis, and Colitis (SASPIC) Study. In this inception cohort, patients ≤45 years of age with ≥3 months back pain undergo diagnostic evaluation by a local SASPIC rheumatologist, including imaging of the SIJ, who then records a global evaluation of presence/absence of axial SpA. This is done at 3 consecutive stages: 1.After the clinical evaluation. 2.After the results of labs (HLA B27, CRP) and radiography. 3.After review of the local MRI. In this exercise, 20 cases were selected from the SASPIC cohort and the rheumatologist global evaluations were removed from the eCRFs. Four experts in axSpA reviewed the clinical and imaging data in each eCRF and provided their global evaluations for stages 1, 2, and 3 of these 20 cases. Subsequently, 4 pF rheumatologists conducted the same exercise blinded to the assessments of the local rheumatologist and experts in axSpA. Concordance (% agreement) between the assessors was analyzed.Results:Diagnosis of axSpA by the local SASPIC rheumatologist was made in 90%, 65%, and 75% of cases after stages 1, 2, and 3, respectively. Majority diagnosis of axSpA by experts was made in 84.2% (16/19), 57.9% (11/19), and 63.2% (12/19), after stages 1,2, and 3, respectively. Majority diagnosis of axSpA by pF rheumatologists was made in 94.4% (17/18), 100% (16/16), and 93.8% (15/16). Concordance among experts and between experts and local SASPIC rheumatologists increased after review of imaging data. For pf-rheumatologists concordance with experts increased after review of imaging for 2 assessors and decreased for the other 2 assessors. For the latter, the primary reason for decrease in concordance with experts was false positive diagnosis of axSpA in 35% and 30% of the cases after review of the imaging.Conclusion:A structured case-based and sequential evaluation of clinical and imaging data suggests a gap in the training of recently graduated rheumatologists, with over-interpretation of imaging leading to false positive diagnosis of axSpA.AssessorsMean % Concordance (range) for diagnosis of axSpAStage 1Stage 2Stage 3Experts in axSpA64.2 (45-80)75.8 (65-85)84.2 (70-95)Local rheumatologist vs Experts in axSpA73.8 (70-80)83.8 (80-85)83.8 (80-90)pF rheumatologist 1 vs Experts consensus78.994.494.7pF rheumatologist 2 vs Experts consensus89.561.168.4pF rheumatologist 3 vs Experts consensus63.272.284.2pF rheumatologist 4 vs Experts consensus89.566.768.4Disclosure of Interests:Walter P.

Abstract
Background:Early diagnosis of rheumatoid arthritis (RA) is hampered by suboptimal accuracy of currently available serological biomarkers. Metabolomics may reveal promising biomarker candidates associated with the biomolecular processes of RA. In this work, we applied a high-performance chemical isotope labeling (CIL) LC-MS technique for in-depth profiling of the amine/phenol-submetabolome in serum samples. To avoid false positives and obtain high-confidence biomarker candidates, we analyzed three independent sets of serum samples collected from RA patients and healthy controls to examine the common effects.Objectives:We aimed to identify a metabolite signature with consistently high accuracy for RA.Methods:Serum samples were taken from 3 RA cohorts, which comprised 50, 49, and 131 RA patients, respectively. Within each cohort, there were sex/age-matched healthy controls: 50 in Cohort 1, 50 in Cohort 2, and 100 in Cohort 3. Among these 446 subjects, 75% were females and the average age was 52.5 years. Amine/phenol-containing metabolites were labeled by12C-dansyl chloride to improve the LC-MS detection. For each cohort, a pooled sample was prepared and labeled by13C-dansyl group to serve as the reference sample for relative quantification. Then the individual samples and the pooled sample were mixed 1:1. Finally, an LC-QTOF-MS platform analyzed the mixtures and output the intensity ratios of12C/13C peak pairs.Results:1,149 amine/phenol-containing metabolites were commonly detected across the three sample sets. Among them, 134 were positively identified by our dansyl-labeling standard library, and 141 were matched to predicted retention times and mass values of dansyl-labeled human metabolites. Visualized by the partial least squares discriminant analysis (PLS-DA), the overall amine/phenol-submetabolome demonstrated clear and consistent differences between healthy controls and the RA groups, with cross-validation Q2 = 0.765, 0.745, 0.793, respectively. The selection of significant metabolites was conducted according to the fold change and false-discovery-rate-adjusted Welch’s t-test. Cohort 1 demonstrated 85 metabolites having higher concentrations in the RA samples than the controls, and 89 metabolites with lowered concentrations. The numbers of increased/decreased metabolites in Cohort 2 and 3 were 87/26 and 90/53, respectively. Importantly, there were 59 significantly discriminatory metabolites commonly found in the three data sets (49 increased and 9 decreased). We picked the top three with the highest univariate classification performance to form a biomarker panel. We implemented the linear support vector machine (SVM) to build the classifier and the receiver operating characteristic (ROC) analysis to measure the performance. The area-under-the-curve (AUC) values (95% confidence interval) were 1.000 (1.000-1.000), 0.992 (0.967-1.000) and 0.902 (0.858-0.945) for the three cohorts, respectively. The results revealed the importance of examining multiple sample sets and even in the worst case (Cohort 3), our biomarker candidates could differentiate RA at 82.5% sensitivity and 82.5% specificity. Particularly, in Cohort 3, there were 30 RA patients negative for anti-cyclic citrullinated peptide and rheumatoid factor, and our metabolite panel demonstrated consistently high performance for differentiating these specific subjects from healthy controls.Conclusion:Metabolites showing significant and consistent changes associated with RA have been identified with high discriminative power.Disclosure of Interests:Wei Han: None declared, Xiaohang Wang: None declared, Liang Li: None declared, Stephanie Wichuk: None declared, Edna Hutchings: None declared, Rana Dadashova: None declared, Joel Paschke: None declared, Walter P Maksymowych Grant/research support from: Received research and/or educational grants from Abbvie, Novartis, Pfizer, UCB, Consultant of: WPM is Chief Medical Officer of CARE Arthritis Limited, has received consultant/participated in advisory boards for Abbvie, Boehringer, Celgene, Eli-Lilly, Galapagos, Gilead, Janssen, Novartis, Pfizer, UCB, Speakers bureau: Received speaker fees from Abbvie, Janssen, Novartis, Pfizer, UCB.

Abstract
Background:The Knee Inflammation MRI Scoring System (KIMRISS) is a semi-quantitative grading tool (range 0-500) used to measure features of inflammation in knee osteoarthritis (OA), including compartment-specific BML scores.Objectives:To investigate; 1) Inter-rater reliability of KIMRISS BML change scores including expert readers and a trainee reader, 2) Validity of KIMRISS BML scores by comparing medial and lateral femoral compartments in surgical and contralateral limbs before and 1 year after medial opening wedge high tibial osteotomy (HTO).Methods:We included 27 patients with varus alignment and medial compartment knee OA [preoperative Kellgren-Lawrence grades ≤3, age = 53.1 ± 5.9, 22 males (81%), body mass index = 29.9 ± 4.3] undergoing unilateral HTO. Sagittal 2D turbo spin-echo sequences were acquired at 3-Tesla in both knees pre and 1-year post HTO after surgical removal of hardware. Femoral BML scores in the medial and lateral compartments were assessed on images blinded to limb and time by masking surgical evidence. Three reviewers independently graded the same 108 images (27 patients, 2 limbs, 2 time points). We evaluated reliability pre-to-post HTO BML change scores in the medial and lateral femur by calculating intraclass correlation coefficients (ICC) and Bland-Altman plots with 80% Limits of Agreement (LoA) for each rater pair.Results:Means and standard deviations are shown in Figure 1. Cumulative percent distribution plots of changes after surgery show both increases and decreases in the medial and lateral femur (Figure 2). When combining all raters, the ICC (95% confidence interval (CI)) for the change in BML score for the surgical knee was 0.81(0.64, 0.91) in the medial femur and 0.73 (0.49, 0.87) in the lateral femur. 80% LOA for change in BML score in the surgical knee was -3.56 to 5.44. ICCs and LoAs for rater pairs are in Table 1. The surgical limb medial femur BML score was significantly greater than all other scores pre and post HTO (Figure 1). There were no significant changes after HTO. The mean change (95% CI) in medial femur BML score of the surgical knee was 1.08 (-1.21, 3.38). Using the mean scores of all raters, we compared BML scores in surgical and contralateral limbs before and after HTO using a 2-way repeated measures (limb by time) ANOVA, seperately for the medial and lateral compartments.Table.Intraclass Correlation Coefficients (95% Confidence Intervals) and 80% Limits of Agreement for change in BMLs scores in the surgical knee.a)Medial compartment12310.63 (0.34, 0.81)230.69 (0.43, 0.85)0.42 (0.06, 0.69)b)Lateral compartment123120.67 (0.41, 0.83)30.79 (0.60, 0.90)0.47 (0.11, 0.72)c)Medial compartment12313-6.09, 8.614-8.10, 9.65-6.03, 7.58d)Lateral compartment12312-3.49, 5.413-4.73, 6.99-3.43, 4.95ICCs in the medial (a) and lateral (b) compartments, and 80% LoA in the medial (c) and lateral (d) compartments. Rater 1 = trainee reader, raters 2-3 = expert readers (one MSK radiologist and one rheumatologist).Fig 1.Means and standard deviations for KIMRISS femoral BML scores in the medial and lateral compartment for the surgical and contralateral knee.Fig 2.Probability plots for the 12-month change after surgery in femoral BML score in the medial (a) and lateral (b) compartments of the surgical knee. Change scores from each of the three raters is shown, as well as the average of all four raters.Conclusion:The KIMRISS can reliably detect differences between femoral BML scores in symptomatic and contralateral limbs, supporting the inter-rater reliability, feasibility and validity of compartment-specific BML scores.Disclosure of Interests:Jenna Schulz: None declared, Trevor Birmingham: None declared, Walter P Maksymowych Grant/research support from: Received research and/or educational grants from Abbvie, Novartis, Pfizer, UCB, Consultant of: WPM is Chief Medical Officer of CARE Arthritis Limited, has received consultant/participated in advisory boards for Abbvie, Boehringer, Celgene, Eli-Lilly, Galapagos, Gilead, Janssen, Novartis, Pfizer, UCB, Speakers bureau: Received speaker fees from Abbvie, Janssen, Novartis, Pfizer, UCB., Robert G Lambert: None declared, Stephany Pritchett: None declared, Frank Beier: None declared, J.

Abstract
Background:A recent consensus from the ASAS MRI group has culminated in updated spine lesion definitions for axial spondyloarthritis (ASAS_MRI_defn)1. There has been no central reader evaluation of MRI scans from the ASAS Classification Cohort (ASAS-CC)2to determine the spectrum of MRI lesions in the spine in this cohort.Objectives:To determine the spectrum of active and structural lesions on MRI images of the spine from the ASAS-CC according to the consensus ASAS_MRI_defnupdate.Methods:ASAS_MRI_defnwere recorded by 9 central readers in an eCRF for global assessment and detailed scoring of each discovertebral unit and postero-lateral structures. Vertebral corner bone marrow edema (VCBME) and corner fat (VCFAT) lesions were recorded if present on 2 slices; facet joint, lateral, and posterior inflammatory lesions were recorded if present on a single slice. Vertebral corner erosion, bone spurs, and ankylosis were each scored on a single slice. Comparison of active and structural lesion frequencies by local rheumatologist diagnosis of axSpA was assessed descriptively according to ≥2 and majority reader (≥5/9) concordant data.Results:MRI scans of the spine were available from 69 cases with axSpA diagnosed in 44/64 (68.8%). VCBME was most frequent with ≥1 lesion in 32(46.4%) and 19 (27.5%) by ≥2 and ≥5/9 readers, respectively. VCFAT was the most frequent structural lesion with ≥1 lesion in 24 (34.8%) and 14 (20.3%) by ≥2 and ≥5/9 readers, respectively. There were significantly more VCBME lesions in axSpA patients than non-axSpA (mean(SD):1.8(2.7) vs 0.3 (0.5)) (p<0.001) while differences in VCFAT were not significant (Table). The presence of ≥2 VCBME had 90-95% specificity for axSpA. Significantly more VCBME and VCFAT were observed in the setting of radiographic sacroiliitis (modified New York criteria (mNY)).Conclusion:Spine lesions on MRI are relatively frequent in patients with undiagnosed back pain presenting to the rheumatologist. The presence of ≥2 VCBME, but not VCFAT, may have some diagnostic utility.References:[1]Maksymowych WP, et al. Arthritis Rheumatol 70 (suppl 10): 654, 2018[2]Rudwaleit et al.

Abstract
Background:Structural damage was identified as an important outcome domain in the Psoriatic Arthritis (PsA) Core Domain Set and should be assessed at least once in the development of a new therapeutic.Objectives:To conduct a systematic literature review (SLR) to identify studies addressing the measurement properties (MPs) for ROIs and appraise the evidence through the OMERACT Filter 2.1 Framework Instrument Selection Algorithm (OFISA). [1]Methods:An SLR was conducted in EMBASE and MEDLINE to identify full-text English studies developing or assessing MPs of ROIs in PsA. Determination of eligibility, data extraction and methodology asssessment were performed by 2 reviewers. MPs were rated according to the ‘Provisional Standards’ and assigned a Red/Amber/White/Green (RAWG) rating (Figure 1). [1, 2]Results:3621 references were screened, 531 full-text articles reviewed, and 12 were included (Figure 2). Nine instruments assessing peripheral radiographs and six assessing axial radiographs were identified (Table 1). Three of the nine peripheral radiographic instruments had adequate evidence for reliability and some evidence for construct validity: the modified Steinbrocker, Ratingen, and modified Sharp van der Heijde scores. There was scant evidence for reliability, construct validity and responsiveness for the axial ROIs, compounded by the lack of a standardized definition of axial PsA.Conclusion:This SLR summarizes the MPs of ROIs and identifies relevant knowledge gaps that need to be addressed prior to endorsement of an instrument for the PsA Core Domain Set.References:[1]Richards P and De Wit M, editors.

Abstract
Background:Ixekizumab (IXE), a high-affinity anti-interleukin-17A monoclonal antibody, is effective in patients (pts) with active non-radiographic axial spondyloarthritis (nr-axSpA), who had elevated C-reactive protein (CRP) and/or active sacroiliitis on magnetic resonance imaging (MRI).1Objectives:To determine if disease activity and patient-reported outcomes at Week 16 were similar between groups after stratifying pts by CRP/sacroiliac joint (SIJ) MRI status at baseline.Methods:COAST-X (NCT02757352) included pts with active nr-axSpA and objective signs of inflammation, i.e. presence of sacroiliitis on MRI (Assessment of Spondyloarthritis International Society [ASAS]/ Outcome Measures in Rheumatology criteria) or elevation of serum CRP (>5.0 mg/L). Pts were randomized 1:1:1 to receive subcutaneous 80 mg IXE every 4 weeks (Q4W) or Q2W, or placebo (PBO). Depending on the baseline values of CRP and MRI SIJ (Spondyloarthritis Research Consortium of Canada [SPARCC] score), pts in the intent-to-treat population (N=239) were divided into 3 subgroups (CRP >5 and MRI ≥2; CRP ≤5 and MRI ≥2; CRP >5 and MRI <2). Logistic regression analysis with treatment, subgroup, and treatment-by-subgroup interaction was used to detect treatment group differences in ASAS40, Ankylosing Spondylitis Disease Activity Score (ASDAS) <2.1 (low disease activity), and Bath Ankylosing Spondylitis Disease Activity Index 50 (BASDAI50) responses at Week 16. Analysis of covariance model with baseline value, treatment, subgroup, and treatment-by-subgroup interaction was used to detect the treatment group difference in change from baseline in Short Form-36 physical component score (SF-36 PCS).Results:The proportion of pts achieving ASAS40 (primary endpoint), ASDAS <2.1, and BASDAI50 (secondary endpoints) was higher in IXE treatment groups compared to PBO at Week 16 (Figure 1). The response rates in IXE-treated subjects were higher in all subgroups (CRP >5 and MRI ≥2; CRP ≤5 and MRI ≥2; CRP >5 and MRI <2) without consistent differences in efficacy between the subgroups. Similarly, pts in the IXE groups showed improvement in SF-36 PCS scores (secondary endpoint) versus pts on PBO at Week 16 (Figure 2).Conclusion:Pts with active nr-axSpA and objective signs of inflammation at baseline who were treated with IXE showed an overall improvement in the signs and symptoms of the disease. The efficacy was not different between pts with both elevated CRP and active sacroiliitis on MRI and pts with either elevated CRP or active sacroiliitis on MRI.References:[1]Deodhar A, et al.Lancet.2020.Disclosure of Interests:Walter P Maksymowych Grant/research support from: Received research and/or educational grants from Abbvie, Novartis, Pfizer, UCB, Consultant of: WPM is Chief Medical Officer of CARE Arthritis Limited, has received consultant/participated in advisory boards for Abbvie, Boehringer, Celgene, Eli-Lilly, Galapagos, Gilead, Janssen, Novartis, Pfizer, UCB, Speakers bureau: Received speaker fees from Abbvie, Janssen, Novartis, Pfizer, UCB., Helena Marzo-Ortega Grant/research support from: Janssen, Novartis, Consultant of: Abbvie, Celgene, Eli Lilly, Janssen, Novartis, Pfizer, UCB, Speakers bureau: Abbvie, Celgene, Eli Lilly, Janssen, Novartis, Pfizer, Takeda, UCB, Mikkel Ǿstergaard Grant/research support from: AbbVie, Bristol-Myers Squibb, Celgene, Merck, and Novartis, Consultant of: AbbVie, Bristol-Myers Squibb, Boehringer Ingelheim, Celgene, Eli Lilly, Hospira, Janssen, Merck, Novartis, Novo Nordisk, Orion, Pfizer, Regeneron, Roche, Sandoz, Sanofi, and UCB, Speakers bureau: AbbVie, Bristol-Myers Squibb, Boehringer Ingelheim, Celgene, Eli Lilly, Hospira, Janssen, Merck, Novartis, Novo Nordisk, Orion, Pfizer, Regeneron, Roche, Sandoz, Sanofi, and UCB, Lianne S.

Abstract
Childbearing women with rheumatoid (RA) and psoriatic arthritis (PsA) have significant peripartum issues. A retrospective anonymous RedCAP survey of peripartum period in females with RA/PsA in the RAPPORT registry was performed. Completed analyses included descriptive statistics, Chi-square and Fisher’s exact test. 162 patients (133 RA/29 PsA) completed the survey (103 women having 234 pregnancies), 164 pregnancies occurring before and 70 pregnancies occurring after diagnosis. Pregnancy outcomes from 103 patients included: 96% live births, 1.9% stillbirths, 23% miscarriages, and 15% therapeutic abortions. A third of patients had fewer children than desired due to disease activity, medications and other reasons. For 63 pregnancies after diagnosis: (1) 49% of pregnancies received pre-conception counseling; (2) 65% described good disease control during pregnancy but 74% flared in the first 3 months postpartum; (3) 79% of pregnancies discontinued IA medications; (4) 35% of pregnancies occurred on biologic therapy at or prior to conception. Gestational age at time of delivery was 37–40 weeks in 58% (33/57) post-arthritis vs 66% (83/126) pre-arthritis pregnancies. No statistically significant differences occurred between pregnancies before or after RA/PsA diagnosis for: pregnancy planning, fertility treatment, pregnancy and labour/delivery complications, birth defect frequency or neonatal complications. Neonatal ICU admissions were significantly lower in pre- compared to post-arthritis pregnancies (3.2% vs 14.5%). No pregnancy complications were noted in 24/54 pregnancies on medications compared to 6/9 pregnancies not on medications. The impact of RA/PsA before, during and after pregnancy varied considerably in this cohort emphasizing the importance of informed-decision making at all stages.

Abstract
Objective We tested the hypothesis that fat metaplasia on MRI of the sacroiliac joints (SIJ) increases the propensity for new bone formation in the spine of patients with spondyloarthritis. Methods We assessed baseline T1-weighted and short τ inversion recovery SIJ MRIs from patients in the Follow Up Research Cohort in Ankylosing Spondylitis (FORCAST). Radiographic progression was assessed using the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). Structural and inflammatory lesions were scored using the Spondyloarthritis Research Consortium of Canada (SPARCC) SIJ structural and SPARCC SIJ inflammation scores, respectively. Radiographic progression was compared in cases with and without definite MRI lesions (score ≥2 or <2) and the extent of MRI lesions at baseline was compared in patients with and without radiographic progression. The predictive capacity of MRI SIJ lesions for radiographic progression in the spine was assessed in univariate and multivariate regression analyses. Results The extent of MRI structural lesions in the SIJ at baseline was significantly greater in those patients who had spinal radiographic progression on follow-up (p=0.003, 0.02, 0.003 for fat metaplasia, backfill and ankylosis, respectively). Also, radiographic progression was significantly greater in cases with definite baseline SIJ ankylosis (p=0.008). In multivariate regression that included all types of MRI lesions and was adjusted for age, sex, symptom duration, duration of follow-up, CRP, baseline mSASSS and treatment, the extent of SIJ fat metaplasia and ankylosis at baseline were independently associated with radiographic progression. Conclusions SIJ ankylosis and fat metaplasia but not inflammatory lesions increase the propensity for radiographic progression in the spine.

Abstract
Introduction The Assessments of SpondyloArthritis international society Health Index (ASAS HI) measures functioning and health in patients with spondyloarthritis (SpA) across 17 aspects of health and 9 environmental factors (EF). The objective was to translate and adapt the original English version of the ASAS HI, including the EF Item Set, cross-culturally into 15 languages. Methods Translation and cross-cultural adaptation has been carried out following the forward–backward procedure. In the cognitive debriefing, 10 patients/country across a broad spectrum of sociodemographic background, were included. Results The ASAS HI and the EF Item Set were translated into Arabic, Chinese, Croatian, Dutch, French, German, Greek, Hungarian, Italian, Korean, Portuguese, Russian, Spanish, Thai and Turkish. Some difficulties were experienced with translation of the contextual factors indicating that these concepts may be more culturally-dependent. A total of 215 patients with axial SpA across 23 countries (62.3% men, mean (SD) age 42.4 (13.9) years) participated in the field test. Cognitive debriefing showed that items of the ASAS HI and EF Item Set are clear, relevant and comprehensive. All versions were accepted with minor modifications with respect to item wording and response option. The wording of three items had to be adapted to improve clarity. As a result of cognitive debriefing, a new response option ‘not applicable’ was added to two items of the ASAS HI to improve appropriateness. Discussion This study showed that the items of the ASAS HI including the EFs were readily adaptable throughout all countries, indicating that the concepts covered were comprehensive, clear and meaningful in different cultures.

Abstract
OBJECTIVE Axial spondyloarthritis (SpA) is a chronic inflammatory disease characterized by back pain and stiffness. The objective of this study was to determine whether golimumab is superior to placebo in patients with nonradiographic axial SpA. METHODS This phase III, double-blind, randomized, placebo-controlled trial was performed to evaluate subcutaneous golimumab (50 mg) versus placebo in patients ages ≥18 years to ≤45 years who had active nonradiographic axial SpA according to the Assessment of SpondyloArthritis international Society (ASAS) criteria for ≤5 years since diagnosis, high disease activity, and an inadequate response to or intolerance of nonsteroidal antiinflammatory drugs. Patients were randomized 1:1 to receive golimumab or placebo subcutaneously every 4 weeks. The primary end point was 20% improvement according to the ASAS criteria (ASAS20) at week 16. Key secondary end points were an ASAS40 response, ASAS partial remission, 50% improvement in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and change in the Spondyloarthritis Research Consortium of Canada (SPARCC) magnetic resonance imaging (MRI) index for sacroiliac (SI) joint inflammation (SPARCC score). RESULTS Of the 198 patients randomized, 197 were treated (97 received golimumab, and 100 received placebo). The mean age of the patients was 31 years, and 57.1% were male. At baseline, the mean ± SD BASDAI was 6.5 ± 1.5, the mean ± SD ASDAS was 3.5 ± 0.9, and the mean ± SD SPARCC score was 11.3 ± 14.0. The primary end point, an ASAS20 response, was achieved by significantly more patients in the golimumab group compared with the placebo group (71.1% versus 40.0%; P < 0.0001). An ASAS40 response was also achieved by significantly more patients in the golimumab group compared with the placebo group (56.7% versus 23.0%; P < 0.0001). The incidence of adverse events did not differ meaningfully between groups. CONCLUSION Patients with active nonradiographic axial SpA treated with golimumab had significantly greater improvement in symptoms compared with patients treated with placebo. Golimumab was well tolerated and had a favorable risk/benefit profile.
