Abstract
OBJECTIVE Smoking and periodontitis are risk factors for developing rheumatoid arthritis (RA), suggesting a break of tolerance on mucosal surfaces. Immunoglobulin A (IgA) antibodies are part of the mucosal immune system. The dominant autoantibodies in RA are anti-cyclic citrullinated protein antibodies (ACPAs), and IgG and IgA subclasses exist simultaneously. This study aimed to investigate the association of ACPA IgA subtypes with disease activity and long-term radiographic outcomes in RA, compared with ACPA IgG. METHOD Total ACPA IgG, IgA, IgA1, and IgA2 were quantified in serum from patients with early RA (n = 97). Patient characteristics, IgM rheumatoid factor (IgM-RF) status, clinical and biochemical disease activity scores, and radiographic status evaluated by total Sharp score (TSS), were assessed at baseline and after 2 and 11 years of treatment. RESULTS All patients with ACPA IgA also had ACPA IgG. ACPA IgA positivity was associated with IgM-RF and male gender. Both ACPA IgA and IgG levels at baseline were weakly associated with disease activity markers. Baseline ACPA IgA and IgG did not show a linear correlation with radiographic status after 10 years, but could predict radiographic progression (ΔTSS ≥ 5 from 0 to 11 years), with positive likelihood ratios of 3.7 and 4.0, respectively. CONCLUSION ACPA IgA and IgG were weakly associated with disease activity in early RA. RA patients with a ΔTSS ≥ 5 after 11 years of treatment had higher ACPA IgG and ACPA IgA levels at baseline; however, none of the ACPA subtypes was superior in predicting long-term radiographic progression.

Abstract
OBJECTIVE Galectin-3 (Gal-3) has been suggested as a proinflammatory mediator in rheumatoid arthritis (RA). We aimed to study clinical and pathogenic aspects of Gal-3 in RA. METHOD Plasma samples from healthy controls (n = 48) and patients with newly diagnosed, early RA were assayed for soluble Gal-3. In patients with chronic RA (n = 18), Gal-3 was measured in both plasma and synovial fluid. Synovial fluid mononuclear cells were used to purify fibroblast-like synoviocytes (FLSs) and osteoclasts. Monocultures of FLSs and autologous co-cultures of FLSs and peripheral blood mononuclear cells were established and co-incubated with a Gal-3 inhibitor. RESULTS Patients with early and chronic RA had persistently increased plasma levels of Gal-3 compared with controls. However, changes in plasma Gal-3 at the level of individuals were associated with long-term disease activity. In seropositive early RA patients, all patients with decreasing plasma Gal-3 from 0 to 3 months had low disease activity after 2 years (p < 0.05). Gal-3 levels in synovial fluid were markedly elevated. In vitro, co-incubation with a Gal-3 inhibitor (GB1107, 10 µM) led to a significant reduction in both interleukin-1β and tumour necrosis factor-α secretion from FLS monocultures (both p < 0.05) and decreased monocyte-derived osteoclastogenesis compared with controls (both p < 0.05). CONCLUSIONS Our findings underscore the role of Gal-3 regarding disease activity and tissue destruction in RA. An initial decrease in plasma Gal-3 levels predicted decreased long-term disease activity. Correspondingly, a Gal-3 inhibitor decreased the activity of inflammatory FLSs and osteoclastogenesis in patients with RA.

Abstract
OBJECTIVE A randomized controlled trial [Joint Resources - Sedentary Behaviour (JR-SB) intervention] aimed to reduce sedentary behaviour and increase light-intensity physical activity in patients with rheumatoid arthritis (RA) through motivational counselling and text messages. Since a large proportion of invited patients declined to participate, this study aims to compare sociodemographic, clinical, and lifestyle factors between included patients and patients declining to participate (non-participants) in the JR-SB study and to investigate which characteristics were associated with participation. METHOD A register-based cross-sectional study was conducted. All patients invited to participate in the JR-SB study were identified in the DANBIO registry, from which patients' clinical and lifestyle data were also retrieved. Data on sociodemography and comorbidity were extracted from national registers. Differences between participants and non-participants were determined by an independent t-test or a chi-squared test. Logistic regression analyses adjusted for various confounders tested the association of patient characteristics with the likelihood of participation in the JR-SB study. RESULTS A total of 467 (58%) declined participation in the JR-SB study. Non-participants were older and less educated, more were smokers, fewer performed regular physical activity, and more had comorbidity compared to participants. Regression analyses showed that a higher educational level and absence of comorbidity in particular were associated with participation in the JR-SB study. CONCLUSION Patients with RA who are less educated and with certain types of comorbidity are less motivated to participate in a physical activity intervention. The findings may inform the recruitment process and implementation of physical activity interventions in rheumatology clinical practice.

Abstract
OBJECTIVE 14-3-3η is a proinflammatory mediator critical to joint destruction in rheumatoid arthritis (RA). We aimed to evaluate serum 14-3-3η for predicting disease activity and radiographic progression in patients with early RA in the double-blinded, randomized OPERA trial. METHOD 180 patients with early RA were randomized to receive methotrexate (MTX) + adalimumab or MTX + placebo in combination with glucocorticoid injections into swollen joints. Disease activity was measured using the 28-joint Disease Activity Score-C-reactive protein (DAS28-CRP). Clinical remission was defined as DAS28-CRP < 2.6. X-rays of hands and feet were evaluated by the Total Sharp van der Heijde score (TSS). Radiographic progression was defined as exceeding the smallest detectable change (1.8 TSS-units). Serum 14-3-3η was determined by enzyme-linked immunosorbent assay. Multivariate logistic regression models were used to identify predictors of DAS28-CRP remission at 6 months and radiographic progression at 12 months. RESULTS Baseline 14-3-3η was a borderline significant independent predictor of radiographic progression at 12 months (odds radio = 1.02, 95% confidence interval 1.00-1.03, p = 0.05). In anti-cyclic citrullinated peptide antibody (ACPA)-negative patients, a moderate/high baseline 14-3-3η concentration increased the risk of radiographic progression at 12 months [4/51 (8%) vs 3/9 (33%), χ2 = 4.823, p = 0.028]. No value of 14-3-3η for predicting achievement of clinical remission was found. CONCLUSION Serum 14-3-3η was a borderline significant predictor of radiographic progression, particularly in ACPA-negative patients, but not of predicting achievement of clinical remission. Optimal cut-off levels of 14-3-3η for predicting radiographic progression in RA need further clarification.

Abstract
OBJECTIVE It remains disputed how much the risk of Staphylococcus aureus bacteraemia (SAB) is increased in patients with rheumatoid arthritis (RA), and the extent to which orthopaedic implants explain the risk. We assessed SAB incidence rates (IRs) and incidence rate ratios (IRRs), comparing RA patients with a general population cohort (GPC) and individuals with versus without orthopaedic implants. METHOD Danish residents aged ≥ 18 years without prior RA or SAB (=GPC) were followed up for RA and microbiologically verified SAB events (1996-2017). IRRs were calculated by age- and sex-stratified Poisson regression adjusted for age, comorbidities, calendar year, and socioeconomic status. RESULTS The GPC comprised 5 398 690 individuals. We identified 33 567 incident RA patients (=RA cohort) (median follow-up 7.3 years, IQR 3.6-12.3). We observed 25 023 SAB events (n = 224 in the RA cohort). IRs per 100 000 person-years were 81.0 (RA cohort) and 29.9 (GPC). IRs increased with age. Adjusted IRRs in 18-59-year-old RA patients were 2.6 (95% confidence interval 1.8-3.7) for women and 1.8 (1.1-3.1) for men, compared with same sex and age group GPC. IRRs declined with age. Compared with the GPC without implants, IRRs for RA patients with implants ranged from 1.9 (1.3-2.8) (women ≥ 70 years) to 5.3 (2.2-12.8) (18-59-year-old men). CONCLUSION In this nationwide registry-based cohort study RA was a risk factor for SAB, and orthopaedic implants further increased the risk. Clinicians should be aware of potential SAB in patients with RA and orthopaedic implants.

Abstract
Objectives: To compare the effect of treat-to-target-based escalations in conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and biologics on clinical disease activity and magnetic resonance imaging (MRI) inflammation in a rheumatoid arthritis (RA) cohort in clinical remission.Method: One-hundred patients with established RA, Disease Activity Score based on 28-joint count-C-reactive protein (DAS28-CRP) < 3.2, and no swollen joints (hereafter referred to as 'in clinical remission') who received csDMARDs underwent clinical evaluation and MRI of the wrist and second to fifth metacarpophalangeal joints every 4 months. They followed a 2 year MRI treatment strategy targeting DAS28-CRP ≤ 3.2, no swollen joints, and absence of MRI osteitis, with predefined algorithmic treatment escalation: first: increase in csDMARDs; second: adding a biologic; third: switch biologic. MRI osteitis and Health Assessment Questionnaire (HAQ) (co-primary outcomes) and MRI combined inflammation and Simplified Disease Activity Index (SDAI) (key secondary outcomes) were assessed 4 months after treatment change and expressed as estimates of group differences. Statistical analyses were based on the intention-to-treat population analysed using repeated-measures mixed models.Escalation to first biologic compared to csDMARD escalation more effectively reduced MRI osteitis (difference between least squares means 1.8, 95% confidence interval 1.0-2.6), HAQ score (0.08, 0.03-0.1), MRI combined inflammation (2.5, 0.9-4.1), and SDAI scores (2.7, 1.9-3.5).Treat-to-target-based treatment escalations to biologics compared to escalation in csDMARDs more effectively improved MRI inflammation, physical function, and clinical disease activity in patients with established RA in clinical remission. Treatment escalation in RA patients in clinical remission reduces clinical and MRI-assessed disease activity.Trial registration: Clinicaltrials.gov identifier: NCT01656278.

Impact of season on the association between vitamin D levels at diagnosis and one-year remission in early Rheumatoid Arthritis. Sci Rep 2020; 10:7371. [PMID: 32355224 PMCID: PMC7192905 DOI: 10.1038/s41598-020-64284-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Accepted: 04/09/2020] [Indexed: 12/20/2022] Open
Abstract
The study evaluates associations between serum vitamin D metabolites at diagnosis and one-year remission, in early diagnosed rheumatoid arthritis(RA). The CIMESTRA-cohort comprised 160 newly diagnosed RA patients, treated aiming at remission. Vitamin D supplementation was recommended according to national guidelines. Dtotal(25OHD2 + 25OHD3) was dichotomized at 50 nmol/L, 1,25(OH)2D was categorized in tertiles. Primary outcome was remission(DAS28-CRP ≤ 2.6) after one year. Associations were evaluated using logistic regression, further adjusted for pre-specified potential confounders: Age, sex, symptom-duration before diagnosis, DAS28-CRP and season of diagnosis. Results are presented as Odds Ratios(OR) with 95% Confidence Intervals(95%CIs). In univariate analyses, neither Dtotal nor 1,25(OH)2D were associated with remission. In adjusted analyses, low Dtotal was associated with higher odds for remission; OR 2.6, 95%CI (1.1; 5.9) p = 0.03, with season impacting results the most. One-year remission was lower in patients with diagnosis established at winter. In conclusion, low Dtotal at diagnosis was associated with increased probability of achieving one-year remission in early RA when adjusting for covariates. Diagnosis in winter was associated with lower odds for one-year remission. Results suggest that season act as a contextual factor potentially confounding associations between vitamin D and RA disease-course. The finding of low Dtotal being associated with higher one-year remission remains speculative.

Abstract
OBJECTIVES Touch screens for entering patient-reported outcomes (PROs) are available at all Danish departments of rheumatology reporting to the nationwide DANBIO registry. This project comprises two substudies in patients with rheumatoid arthritis (RA) or axial spondyloarthritis (AxSpA), aiming to (A) investigate the feasibility of first line patient recruitment for research via touch screens, and (B) compare PROs collected at hospital versus at home, including patient preferences. METHOD Substudy A: using a touch screen, patients answered whether we could contact them about a clinical research project (yes/no). Characteristics of patients who accepted/declined were explored using chi-squared and Mann-Whitney U-tests. Substudy B (randomized crossover agreement study): a random sample of patients from the accepting group in substudy A was contacted by telephone. According to prespecified power and sample size estimation, 56 patients were included. After randomization, 50% of patients entered PROs and information on comorbidities and lifestyle from home and then at hospital, and 50% first from hospital and then at home. Finally, they stated their preference for data entry (hospital/home/equally good). Differences in PROs entered from home and in the hospital were compared (limits of agreement, 95% confidence intervals, and intraclass correlation coefficients). RESULTS The touch-screen invitation was accepted by 428/952 patients (45%). Patients who accepted and those who declined had similar PROs and demographics. Substudy B was completed by 42 patients (22 RA, 20 AxSpA). They had no significant differences between PROs and lifestyle/comorbidity data entered from home and hospital, except for AxSpA patients on the Bath Ankylosing Spondylitis Functional Index and Bath Ankylosing Spondylitis Disease Activity Index item 5. The preferred method of data entry was hospital (10%), home (50%), and equally good (40%). CONCLUSION Touch screens seem feasible for first line research recruitment. PROs collected from home were similar to the touch-screen solution. Patients preferred data entry from home.

Abstract
OBJECTIVES To investigate whether smoking habits predict response to rituximab (RTX) in rheumatoid arthritis (RA). METHOD We included patients from the CERERRA international cohort receiving the first treatment cycle with available smoking status (n = 2481, smokers n = 528, non-current smokers n = 1953) and at least one follow-up visit. Outcome measures were change in Disease Activity Score based on 28-joint count (ΔDAS28) and European League Against Rheumatism (EULAR) good response at 6 months, with non-current smokers as the referent group. RESULTS Compared with non-smokers at baseline, smokers were more often rheumatoid factor (RF)/anti-citrullinated protein antibody (ACPA) positive and males, had shorter disease duration, lower DAS28 and Health Assessment Questionnaire (HAQ) score, a higher number of prior biological disease-modifying anti-rheumatic drugs, and were more likely to receive concomitant conventional synthetic disease-modifying anti-rheumatic drug (csDMARDs). Disease activity had decreased less in smokers at 6 months (ΔDAS28 = 1.5 vs 1.7, p = 0.006), although the difference was no longer significant after correction for baseline DAS28 (p = 0.41). EULAR good response rates did not differ between smokers and non-smokers overall or stratified by RF/ACPA status, although smokers had lower good response rates among seronegative patients (ACPA-negative: 6% vs 14%, RF-negative: 11% vs 18%). Smoking did not predict good response [odds ratio (OR) = 1.04, 95% confidence interval (CI) = 0.76-1.41], while ACPA, DAS28, HAQ, and concomitant csDMARDs were significant predictors for good response. However, when stratified by country, smokers were less likely to achieve good response in Sweden (unadjusted OR = 0.24, 95% CI = 0.07-0.89), and a trend was seen in the Czech Republic (OR = 0.45, 95% CI = 0.16-1.02). CONCLUSION In this large, observational, multinational RA cohort, smokers starting RTX differed from non-smokers by having shorter disease duration and lower disease activity, but more previous treatments. The overall results do not support smoking as an important predictor for response to RTX in patients with RA.

Abstract
OBJECTIVE To investigate whether axial spondyloarthritis (axSpA) patients with extremely poor patient-reported outcomes (PROs) at start of first tumour necrosis factor inhibitor (TNFi) treatment have poorer treatment response and shorter treatment retention than other patients. METHOD This observational cohort study was based on the nationwide DANBIO registry. Patients with axSpA who started first TNFi during 2011-2016 were stratified according to baseline Bath Ankylosing Spondylitis Disease Activity Index (BASDAI ≥ 0.0 to ≤ 4.0, > 4.0 to ≤ 5.0, > 5.0 to ≤ 6.0, > 6.0 to ≤ 7.0, > 7.0 to ≤ 8.0, > 8.0 to ≤ 9.0, and > 9.0 to ≤ 10.0). An extremely poor BASDAI was defined as BASDAI > 9.0 to ≤ 10.0. Treatment responses after 6 months [≥ 50% improvement from baseline BASDAI (BASDAI50), ≥ 40% improvement in Assessment of SpondyloArthritis international Society (ASAS40) response, and ASAS partial remission] in patients with extremely poor PROs were compared with other patients by chi-squared tests, and retention rates by log-rank tests. Similar analyses were done for Bath Ankylosing Spondylitis Functional Index (BASFI), pain score, and patient global score. RESULTS The study included 1396 patients (median age 39 years, 60% men). Patients with extremely poor baseline BASDAI [63 patients (5%)] were more often women, ever smokers, and human leucocyte antigen-B27 negative, and had higher body mass index. Response rates were poorer in patients with extremely poor BASDAI vs remaining patients (BASDAI50 19% and 41%, respectively, p < 0.001; ASAS40 16% and 35%, p = 0.002; ASAS partial remission 6% and 22%, p < 0.001). Patients with extremely poor BASDAI had lower 1 year treatment retention (51% and 68%, p < 0.001). Largely similar results were found for patients with extremely poor BASFI, pain score, and patient global score. CONCLUSION Patients who reported an unusually large symptom burden at baseline had poor response rates and low retention rate. In such cases, competing causes of pain should carefully be taken into account when considering treatment with TNFi.

Abstract
OBJECTIVES Measurement of serum biomarkers at disease onset may improve prediction of disease course in patients with early rheumatoid arthritis (RA). We evaluated the multi-biomarker disease activity (MBDA) score and early changes in MBDA score for prediction of 28-joint Disease Activity Score based on C-reactive protein (DAS28-CRP) remission and radiographic progression in the double-blinded OPERA trial. METHOD Treatment-naïve RA patients (N = 180) with moderate or high DAS28 were randomized to methotrexate (MTX) + adalimumab (n = 89) or MTX + placebo (n = 91) in combination with glucocorticoid injection into swollen joints. X-rays of hands and feet were evaluated at months 0 and 12 (n = 164) by the total Sharp van der Heijde score (TSS). The smallest detectable change (1.8 TSS units) defined radiographic progression (∆TSS ≥ 2). Clinical remission (DAS28-CRP < 2.6) was assessed at baseline and 6 months. MBDA score was determined at 0 and 3 months and tested in a multivariable logistic regression model for predicting DAS28 remission at 6 months and radiographic progression at 1 year. RESULTS Baseline MBDA score was independently associated with radiographic progression at 1 year [odds ratio (OR) = 1.03/unit, 95% confidence interval (CI) = 1.01-1.06], and changes in MBDA score from baseline to 3 months with clinical remission at 6 months [OR = 0.98/unit, 95% CI 0.96-1.00). In anti-cyclic citrullinated peptide antibody (anti-CCP)-positive patients, 35 of 89 with high MBDA score (> 44) showed radiographic progression (PPV = 39%), compared with 0 of 15 patients (NPV = 100%) with low/moderate MBDA score (≤ 44) (p = 0.003). CONCLUSION Early changes in MBDA score were associated with clinical remission based on DAS28-CRP at 6 months. In anti-CCP-positive patients, a non-high baseline MBDA score (≤ 44) had a clinical value by predicting very low risk of radiographic progression at 12 months.

Abstract
OBJECTIVE To investigate serum interleukin-6 (IL-6), serum chitinase-3-like protein-1 (YKL-40), and plasma vascular endothelial growth factor (VEGF) as measures of disease activity and predictors of clinical remission and radiographic progression in two early rheumatoid arthritis (RA) randomized controlled trials (RCTs). METHOD Treatment-naïve patients with early RA (< 6 months' duration) and active disease, participating in two investigator-initiated RCTs, were treated according to a predefined treat-to-target algorithm aiming at inflammatory control, using methotrexate (MTX) + cyclosporine versus MTX + placebo (CIMESTRA study, n = 150, 5 year follow-up) or MTX + adalimumab versus MTX + placebo (OPERA study, n = 180, 2 year follow-up). The 28-joint Disease Activity Score (DAS28) and conventional radiography [bilateral hands and feet at baseline, 2 years and 5 years (only CIMESTRA)] were obtained at baseline and during follow-up. Serum IL-6, serum YKL-40, and plasma VEGF were measured in baseline blood samples and during follow-up. Hypotheses regarding the biomarkers' relation with DAS28 and ability to predict clinical remission (DAS28 < 2.6) and radiographic progression (change in total Sharp van der Heijde score ≥ 2) were generated in CIMESTRA and validated in OPERA, by Spearman's correlation and logistic regression analyses. RESULTS Baseline IL-6, YKL-40, and VEGF correlated significantly with DAS28 in CIMESTRA (r = 0.50, r = 0.36, r = 0.36, respectively, all p < 0.01) and these results were confirmed in OPERA patients (r = 0.52, p < 0.01; r = 0.18, p = 0.01; r = 0.23, p = 0.002, respectively). None of the biomarkers (absolute values or change) was predictive of clinical remission or radiographic progression at 2 or 5 years in either study. CONCLUSION Serum IL-6, serum YKL-40, and plasma VEGF were significantly correlated with DAS28 at baseline, but did not have consistent predictive value for clinical remission or radiographic progression in two early RA RCTs.

Galectin-3 is Persistently Increased in Early Rheumatoid Arthritis (RA) and Associates with Anti-CCP Seropositivity and MRI Bone Lesions, While Early Fibrosis Markers Correlate with Disease Activity. Scand J Immunol 2017; 86:471-478. [PMID: 28990250 DOI: 10.1111/sji.12619] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2017] [Accepted: 10/03/2017] [Indexed: 01/16/2023]
Abstract
Galectin-3 has been suggested as a pro-inflammatory mediator in animal arthritis and rheumatoid arthritis (RA). We aimed to study the serum level of galectin-3 in patients with newly diagnosed RA and associations with disease profile, Magnetic resonance imaging (MRI) findings and seromarkers of synovial matrix inflammation. One hundred and sixty DMARD naïve patients newly diagnosed with RA were included (CIMESTRA study). Clinical, serological and imaging data were recorded before treatment and at 6 weeks, 3 and 12 months. Galectin-3 and hyaluronan (HYA) were measured by ELISA (R&D and Corgenix, USA), and the N-terminal propeptide of type III collagen (PIIINP) by radioimmunoassay (Orion Diagnostica, Finland). One hundred and nineteen, 87 and 60 blood donors served as controls for galectin-3, HYA and PIIINP, respectively. Baseline galectin-3 was significantly elevated in anti-CCP positive (4.2 μg/l IQR [3.6;6.1]) patients as compared with anti-CCP negatives (4.0 μg/l [2.6;4.9], P = 0.05) and controls (3.8 μg/l [3.0;4.8], P < 0.01). During treatment, galectin-3 remained elevated, but increased transiently with peak values at 6 weeks. Galectin-3 correlated with baseline smoking, anti-CCP, and with MRI erosion score after 1 year of follow-up. HYA and PIIINP were elevated (P < 0.001) irrespective of anti-CCP status and correlated positively with synovitis assessed clinically and by MRI. HYA and PIIINP did not correlate with galectin-3. These observations indicate that HYA and PIIINP mainly reflect expansive synovitis proliferation while galectin-3 is more closely linked to autoimmunity, smoking and joint destructive processes.

Brief Report: Association of Rheumatoid Factor and Anti-Citrullinated Protein Antibody Positivity With Better Effectiveness of Abatacept: Results From the Pan-European Registry Analysis. Arthritis Rheumatol 2017; 68:1346-52.

Abstract
OBJECTIVE To investigate the role of rheumatoid factor (RF) status and anti-citrullinated peptide antibody (ACPA) status as predictors of abatacept (ABA) effectiveness in patients with rheumatoid arthritis (RA). METHODS We conducted a pooled analysis of data from 9 observational RA registries in Europe (ARTIS [Sweden], ATTRA [Czech Republic], BIOBADASER [Spain], DANBIO [Denmark], GISEA [Italy], NOR-DMARD [Norway], ORA [France], Reuma.pt [Portugal], and SCQM-RA [Switzerland]). Inclusion criteria were a diagnosis of RA, initiation of ABA treatment, and available information on RF and/or ACPA status. The primary end point was continuation of ABA treatment. Secondary end points were ABA discontinuation for ineffectiveness or adverse events and response rates at 1 year (good or moderate response according to the European League Against Rheumatism criteria with LUNDEX adjustment for treatment continuation). Hazard ratios (HRs) and 95% confidence intervals (95% CIs) for the study end points in relation to RF and ACPA status were calculated. RESULTS We identified 2,942 patients with available data on RA-associated autoantibodies; data on RF status were available for 2,787 patients (77.0% of whom were RF positive), and data on ACPA status were available for 1,903 patients (71.3% of whom were ACPA positive). Even after adjustment for sociodemographic and disease- and treatment-related confounders, RF and ACPA positivity were each associated with a lower risk of ABA discontinuation for any reason (HR 0.79 [95% CI 0.69-0.90], P < 0.001 and HR 0.78 [95% CI 0.68-0.90], P < 0.001, respectively), compared to RF-negative and ACPA-negative patients. Similar associations with RF and ACPA were observed for discontinuation of ABA treatment due to ineffectiveness, with HRs of 0.72 (95% CI 0.61-0.84) and 0.74 (95% CI 0.62-0.88), respectively (both P < 0.001). CONCLUSION Our results strongly suggest that positivity for RF or ACPA is associated with better effectiveness of ABA therapy.

Abstract
OBJECTIVE A reduction in haemoglobin level is a frequent complication among rheumatoid arthritis (RA) patients. Hepcidin has been linked to disturbed erythropoiesis. The objective of this study was to investigate the longitudinal changes in hepcidin in patients with early RA. METHOD Hepcidin plasma concentrations were measured by enzyme-linked immunosorbent assay in patients with early RA (n = 80) and healthy volunteers (HV, n = 40). Haemoglobin and other iron-related proteins were also measured. At baseline, all patients had active disease and were treatment naïve. Patients were treated with disease-modifying anti-rheumatic drugs (DMARDs) and with additional adalimumab (ADA, n = 42) or placebo (PLA, n = 38) during 52 weeks, using a treat-to-target strategy, aiming for a 28-joint Disease Activity Score (DAS28) < 3.2. RESULTS At baseline, hepcidin levels [median (interquartile range)] were 9.7 ng/mL (5.2-19.4 ng/mL) in DMARD + ADA and 11.3 ng/mL (5.9-19.1 ng/mL) in DMARD + PLA. Both were significantly higher than seen in HV (6.0 ng/mL (3.3-9.3 ng/mL) (p < 0.001). After 12 months, both treatment regimens resulted in normalization of hepcidin. DAS28 correlated with hepcidin at baseline (r = 0.48, p < 0.001). No correlation was observed between levels of haemoglobin and hepcidin at baseline or during the 52 week follow-up. No change in haemoglobin levels was seen as a function of hepcidin changes. In a mixed statistical model, no single factor was connected with the regulation of haemoglobin in early RA. CONCLUSION The changes in hepcidin were not associated with changes in haemoglobin levels. Thus, hepcidin could not be used as a prognostic marker in patients with early RA.

Abstract
INTRODUCTION Cardiovascular morbidity and mortality is increased in patients with rheumatoid arthritis (RA), and among these patients, the prevalence of hypovitaminosis D is high. Moreover, low vitamin D levels have been associated with increased cardiovascular risk in healthy subjects. OBJECTIVE To evaluate the long-term risk of cardiovascular events in patients having low total 25-hydroxyvitamin D levels at baseline compared with patients with normal levels, in an efficiently treated, closed cohort of patients with an early diagnosis of RA. METHODS AND ANALYSIS This study is a prospective, closed, blinded endpoint cohort study, based on secondary analyses from a previous randomised trial (CIMESTRA study; NCT00209859, approved September 1999) including 160 patients with an early diagnosis of RA from Danish University clinics. Primary outcome will be the proportion of patients with any cardiovascular event in the follow-up period, evaluated using systematic journal audits. Logistic regression models will test the hypothesis that there are more cardiovascular events in enrolled patients with a low level of vitamin D (< 50 nmol/L). Secondarily, Cox regression models, based on survival analysis, will determine the extent to which independent variables (including different levels of vitamin D at baseline) predict whether a cardiovascular event will occur, and also when this will be. ETHICS AND DISSEMINATION All patients have received verbal and written information before enrolment, and have given written consent at baseline. To disseminate comprehension of factors of prognostic importance to cardiovascular outcome in RA, we will attempt to have a first draft ready no later than 1 year after the adjudication process has finished. If low vitamin D levels can predict cardiovascular events in RA, it is relevant to take into account in a prediction model, to be considered by patients, physicians and other decision-makers. TRIAL REGISTRATION NUMBER The parental controlled trial is registered as NCT00209859.

Abstract
OBJECTIVE To investigate changes in whole-body magnetic resonance imaging (WBMRI) inflammatory and structural lesions in most joints and entheses in patients with rheumatoid arthritis (RA) treated with adalimumab. METHODS WBMRI was obtained at weeks 0, 6, 16, and 52 in a 52 week follow-up study of 37 RA patients starting treatment with adalimumab. Readability and reliability of WBMRI were investigated for 76 peripheral joints, 23 discovertebral units, the sacroiliac joints, and 33 entheses. Changes in WBMRI joint and entheses counts were investigated. RESULTS The readability of peripheral and axial joints was 82-100%, being less for elbows and small joints of the feet. For entheses, 72-100% were readable, except for entheses at the anterior chest wall, elbow, knee, and plantar fascia. The intrareader agreement was high for bone marrow oedema (BMO), bone erosion (80-100%), and enthesitis (77-100%), and slightly lower for synovitis and soft tissue inflammation (50-100%). All synovitis, BMO, and soft tissue inflammation counts decreased numerically during treatment. The 26-joint synovitis WBMRI count decreased significantly during the first 16 weeks for patients with a good European League Against Rheumatism (EULAR) response (from median 6 to 4, p < 0.05), but not for patients with a moderate or no EULAR response. There were no overall changes in structural lesions. CONCLUSIONS WBMRI allows simultaneous monitoring of most axial and peripheral joints and entheses in RA patients and can visualize a decrease in inflammatory counts during treatment. This first WBMRI follow-up study of patients with RA encourages further investigation of the usefulness of WBMRI in RA.

Hand bone loss in early rheumatoid arthritis during a methotrexate-based treat-to-target strategy with or without adalimumab-a substudy of the optimized treatment algorithm in early RA (OPERA) trial. Clin Rheumatol 2016; 36:781-789. [PMID: 27921185 DOI: 10.1007/s10067-016-3489-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2016] [Revised: 10/21/2016] [Accepted: 11/17/2016] [Indexed: 01/01/2023]
Abstract
This study aims to investigate 1-year hand bone loss (HBL1-year) in early rheumatoid arthritis (RA) patients treated with a methotrexate (MTX) and intra-articular triamcinolone treat-to-target strategy +/- adalimumab and to determine if HBL6months is associated with radiographic progression after 2 years. In a clinical trial (OPERA) of 180 treatment-naive early RA patients, bone mineral density (BMD) was estimated from hand radiographs with digital X-ray radiogrammetry (DXR) at baseline, after 6 (n = 90) and 12 months (n = 70) of follow-up. Baseline and 2-year radiographs were scored according to the Sharp/van der Heijde method. Baseline characteristics and HBL6months (0-6 months changes in DXR-BMD) were investigated as predictors of structural damage by univariate linear (∆ total Sharp/van der Heijde score (TSS) as dependent variable) and logistic (+/-radiographic progression (∆TSS >0) as dependent variable) regression analyses. Variables with p < 0.10 were included in multivariable models. In 70 patients with available HBL1-year data, HBL1-year was median (interquartile range (IQR)) -1.9 (-3.3; -0.26 mg/cm2) in the MTX + placebo group and -1.8 (-3.6; 0.06) mg/cm2 in the MTX + adalimumab group, p = 0.98, Wilcoxon signed-rank. Increased HBL (compared to general population reference values) was found in 26/37 and 23/33 patients in the MTX + placebo and MTX + adalimumab groups, chi-squared = 0.99. In 90 patients with HBL6months data and 2-year radiographic data, HBL6months was independently associated with ∆TSS after 2 years (β = -0.086 (95% confidence interval = -0.15; -0.025) TSS unit/mg/cm2 increase, p = 0.006) but not with presence of radiographic progression (∆TSS >0) (OR 0.96 (0.92-1.0), p = 0.10). In early RA patients treated with a methotrexate-based treat-to-target strategy, the majority of patients had increased HBL1-year, irrespective of adalimumab; HBL6months was independently associated with ∆TSS after 2 years.

Abstract
OBJECTIVES To investigate whether a treat-to-target strategy based on methotrexate (MTX) and intra-articular (IA) betamethasone suppresses magnetic resonance imaging (MRI)-determined measures of disease activity and reduces joint destruction in early rheumatoid arthritis (eRA) patients, and to investigate whether concomitant cyclosporin A (CyA) provides an additional effect. METHOD In the 2-year randomized, double-blind, treat-to-target trial CIMESTRA, 160 patients with eRA (< 6 months) were randomized to MTX, intra-articular betamethasone and CyA, or placebo CyA. A total of 129 patients participated in the MRI substudy, and had contrast-enhanced MR images of the non-dominant hand at months 0, 6, 12, and 24. MR images were evaluated for osteitis, synovitis, tenosynovitis, bone erosion, and joint space narrowing (JSN), using validated scoring methods. RESULTS Significant reductions were seen at 6 months in all inflammatory parameters [synovitis, mean change -1.6 (p < 0.001, Wilcoxon), tenosynovitis, -3.5 (p < 0.001), and osteitis, -1.3 (p < 0.05)] and at 12/24 months in synovitis and tenosynovitis [-1.6/-2.2 and -3.6/-3.8, respectively; all p < 0.001]. MRI signs of inflammation were not fully eliminated, and increases in erosion and JSN scores were observed at 6 months [0.4 (p < 0.01)/0.1 (p < 0.05)], 12 months [0.8 (p < 0.001)/0.3 (p < 0.01)], and 24 months [1.0 (p < 0.001)/0.4 (p < 0.001)]. Clinical measures decreased significantly (p < 0.001) at all time points. There were no consistent statistically significant differences between treatment groups. CONCLUSIONS In this eRA treat-to-target trial, MTX and intra-articular glucocorticoids markedly reduced, but did not eliminate, MRI osteitis, synovitis, and tenosynovitis. Accordingly, minimal but statistically significant increases in bone erosion and JSN were observed. No additional effect of CyA was demonstrated.

Motivational counselling and SMS-reminders for reduction of daily sitting time in patients with rheumatoid arthritis: a descriptive randomised controlled feasibility study. BMC Musculoskelet Disord 2016; 17:434. [PMID: 27756265 PMCID: PMC5070122 DOI: 10.1186/s12891-016-1266-6] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Accepted: 09/24/2016] [Indexed: 12/12/2022] Open
Abstract
Background Patients with rheumatoid arthritis (RA) spend a high proportion of their waking time in sedentary behaviour (SB) and have an increased risk of cardiovascular disease. Reduction of SB and increase in light intensity physical activity has been suggested as a means of improvement of health in patients with mobility problems. Short-term intervention studies have demonstrated that SB can be reduced by behavioural interventions in sedentary populations. To evaluate descriptively the feasibility of recruitment, randomisation, outcome assessments, retention and the acceptability of an individually tailored, theory-based behavioural intervention targeting reduction in daily sitting time in patients with RA. Methods A randomised, controlled trial with two parallel groups. RA patients >18 years of age and Health Assessment Questionnaire (HAQ) score < 2.5 were consecutively invited and screened for daily leisure time sitting > 4 h. The 16-week intervention included 1) three individual motivational counselling sessions and 2) individual text message reminders aimed at reducing daily sitting time. The control group was encouraged to maintain their usual lifestyles. Outcomes were assessed at baseline and after the 16 week intervention. Daily sitting time was measured using an ActivPAL3TM activity monitor. The study was not powered to show superiority; rather the objective was to focus on acceptability among patients and clinical health professionals. Results In total, 107 patients were invited and screened before 20 met eligibility criteria and consented; reasons for declining study participation were mostly flares, lack of time and co-morbidities. One patient from the control group dropped out before end of intervention (due to a RA flare). Intervention participants completed all counselling sessions. All procedures regarding implementation of the trial protocol were feasible. The daily sitting time was reduced on average by 0.30 h in the intervention group unlike the control group that tended to increase it by 0.15 h after 16 weeks. Conclusions This study shows that an individually tailored behavioural intervention targeting reduction of SB was feasible and acceptable to patients with RA.

Abstract
OBJECTIVES To investigate the multi-biomarker disease activity (MBDA) score by comparison with imaging findings in an investigator-initiated rheumatoid arthritis (RA) trial (HURRAH trial, NCT00696059). METHOD Fifty-two patients with established RA initiated adalimumab treatment and had magnetic resonance imaging (MRI), ultrasonography (US), computed tomography (CT), and radiography performed at weeks 0, 26, and 52. Serum samples were analysed using MBDA score assays and associations between clinical measures, MBDA score, and imaging findings were investigated. RESULTS The MBDA score correlated significantly with MRI synovitis (rho = 0.65, p < 0.001), MRI bone marrow oedema (rho = 0.36, p = 0.044), and US power Doppler (PD) score at week 26 (rho = 0.35, p = 0.039) but not at week 0 or week 52. In the 15 patients who had achieved a Disease Activity Score based on C-reactive protein (DAS28-CRP) < 2.6 at week 26, MRI and/or US detected subclinical inflammation and 13 (87%) had a moderate/high MBDA score. For the cohort with available data, none of the four patients in MBDA remission (score ≤ 25) at week 26 had progression of imaging damage from baseline to week 52 whereas progression was observed in three out of nine (33%) and seven out of 21 (33%) patients with moderate (30-44) and high (> 44) MBDA scores, respectively. CONCLUSIONS In this cohort, the MBDA score correlated poorly with MRI/US inflammation. However, the MBDA score and MRI/US were generally concordant in showing signs of inflammation in most patients in clinical remission during anti-tumour necrosis factor (anti-TNF) therapy. MBDA scores were elevated in all patients with structural damage progression.

Abstract
Background Response to disease modifying antirheumatic drugs (DMARDs) in rheumatoid arthritis (RA) is often heterogeneous. We aimed to identify types of disease activity trajectories following the initiation of a new biologic DMARD (bDMARD). Methods Pooled analysis of nine national registries of patients with diagnosis of RA, who initiated Abatacept and had at least two measures of disease activity (DAS28). We used growth mixture models to identify groups of patients with similar courses of treatment response, and examined these patients' characteristics and effectiveness outcomes. Findings We identified three types of treatment response trajectories: ‘gradual responders’ (GR; 3576 patients, 91·7%) had a baseline mean DAS28 of 4·1 and progressive improvement over time; ‘rapid responders’ (RR; 219 patients, 5·6%) had higher baseline DAS28 and rapid improvement in disease activity; ‘inadequate responders’ (IR; 103 patients, 2·6%) had high DAS28 at baseline (5·1) and progressive worsening in disease activity. They were similar in baseline characteristics. Drug discontinuation for ineffectiveness was shorter among inadequate responders (p = 0.03), and EULAR good or moderate responses at 1 year was much higher among ‘rapid responders’ (p < 0.001). Interpretation Clinical information and baseline clinical characteristics do not allow a reliable prediction of which trajectory the patients will follow after bDMARD initiation. This study examined disease activity trajectories in a multinational cohort of 3898 rheumatoid arthritis patients. Growth mixture models identified three groups: gradual, rapid, and inadequate responders (GR: 91·7%, RR: 5·6%, IR: 2·6%). At baseline, groups were similar in demographic and clinical characteristics, and moderately different in function and disease activity. The groups had large difference in drug retention and in good or moderate response rate. Using nine national registries, this study of 3898 established RA patients initiating a new bDMARD identified distinct types of responders: gradual, rapid and inadequate responders. Neither socio-demographic nor clinical characteristics at baseline allowed the prediction of the type of response trajectory after treatment initiation, but effectiveness outcomes strongly differed, suggesting that these empirically derived subgroups have clinical relevance. As a major aim of precision medicine is to make anti-rheumatic therapy more personalized, the detection of responder types following initiation of a specific bDMARD underscores the need to find reliable predictors of trajectories to identify patients needing a distinct treatment strategy.

Abstract
OBJECTIVES To investigate the levels of interleukin (IL)-23 in patients with early rheumatoid arthritis (eRA) and the effect of anti-tumour necrosis factor (anti-TNF)-α treatment on IL-23 levels. METHOD Treatment-naïve eRA patients from the OPERA cohort were included (n = 151). Patients were randomized to methotrexate (MTX) plus adalimumab (ADA; n = 75) or MTX plus placebo-ADA (PLA; n = 76). Plasma samples were obtained at baseline and at months 3, 6, and 12 together with values for C-reactive protein (CRP), the 28-joint Disease Activity Score based on CRP (DAS28CRP), scores on the Clinical Disease Activity Index (CDAI) and the Simplified Disease Activity Index (SDAI), visual analogue scale (VAS) for pain/fatigue/physician global and total Sharp/van der Heijde score (TSS). IL-23 was measured at each time point. RESULTS IL-23 levels decreased significantly in the ADA group from 20.6 pg/mL (IQR 13.1-32.7 pg/mL) at baseline to 18 pg/mL (IQR 7.2-25.0 pg/mL) at 12 months (p < 0.01). No significant decrease in IL-23 level was observed in the PLA group. No associations between baseline IL-23 levels and measures of disease activity (DAS28CRP, CRP, CDAI, or SDAI) at 12 or 24 months were present in the treatment groups. Baseline IL-23 correlated inversely with changes in TSS and symptom duration before diagnosis. CONCLUSIONS Our data show increased baseline levels and a significant decrease in IL-23 levels in eRA patients treated with anti-TNF-α. The inverse correlation with duration of symptoms before diagnosis supports the importance of IL-23 in the preclinical disease development of RA.

Clinical and radiographic outcome of a treat-to-target strategy using methotrexate and intra-articular glucocorticoids with or without adalimumab induction: a 2-year investigator-initiated, double-blinded, randomised, controlled trial (OPERA). Ann Rheum Dis 2015; 75:1645-53. [PMID: 26489704 DOI: 10.1136/annrheumdis-2015-208166] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2015] [Accepted: 09/29/2015] [Indexed: 12/21/2022]
Abstract
OBJECTIVES To study clinical and radiographic outcomes after withdrawing 1 year's adalimumab induction therapy for early rheumatoid arthritis (eRA) added to a methotrexate and intra-articular triamcinolone hexacetonide treat-to-target strategy (NCT00660647). METHODS Disease-modifying antirheumatic drug (DMARD)-naive patients with eRA started methotrexate (20 mg/week) and intra-articular triamcinolone (20 mg/ml) for 2 years. In addition, they were randomised to receive placebo adalimumab (DMARD group, n=91) or adalimumab (40 mg/every other week) (DMARD+adalimumab group, n=89) during the first year. Sulfasalazine and hydroxychloroquine were added if disease activity persisted after 3 months. During year 2, synthetic DMARDs continued. Adalimumab was (re)initiated if active disease reoccurred. Clinical response, remission, disability, quality of life and radiographic changes were assessed. RESULTS One year after adalimumab withdrawal, treatment profiles and clinical responses did not differ between groups. In the DMARD/DMARD+adalimumab groups, the median 2-year methotrexate dose was 20/20 mg/week (p=0.45), triple DMARD therapy had been initiated in 33/27 patients (p=0.49), adalimumab was (re)initiated in 12/12 patients and cumulative triamcinolone dose was 160/120 mg (p=0.15). The treatment target (disease activity score, 4 variables, C-reactive protein (DAS28CRP) ≤3.2 or DAS28>3.2 without swollen joints) was achieved at all visits in ≥85% of patients in year 2; remission rates were DAS28CRP<2.6:69%/66%; Clinical Disease Activity Index ≤2.8:55%/57%; Simplified Disease Activity Index <3.3:54%/49%; American College of Rheumatology/European League against Rheumatism (28 joints):44%/45% (p=0.66-1.00). Radiographic progression (Δtotal Sharp score/year) was similar 1.31/0.53 (p=0.12). Erosive progression (Δerosion score (ES)/year) was year 1:0.57/0.06 (p=0.02); year 2:0.38/0.05 (p=0.005). Proportion of patients without erosive progression (ΔES≤0) was year 1: 59%/76% (p=0.03); year 2:64%/79% (p=0.04). CONCLUSIONS An aggressive triamcinolone and synthetic DMARD treat-to-target strategy in eRA provided excellent 2-year clinical and radiographic disease control independent of adalimumab induction therapy. ES progression was slightly less during and following adalimumab induction therapy. TRIAL REGISTRATION NUMBER NCT00660647.

The impact of patient heterogeneity and socioeconomic factors on abatacept retention in rheumatoid arthritis across nine European countries. RMD Open 2015; 1:e000040. [PMID: 26509062 PMCID: PMC4613166 DOI: 10.1136/rmdopen-2014-000040] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Revised: 03/06/2015] [Accepted: 03/11/2015] [Indexed: 01/06/2023] Open
Abstract
Background There are substantial differences in accessibility to biological disease modifying antirheumatic drugs (bDMARDs) across countries. The objective of this study was to analyse the impact of patient demographics, disease characteristics and gross domestic product (GDP) on abatacept (ABA) retention in patients with rheumatoid arthritis (RA) treated in clinical practice. Methods Data from nine European observational RA cohorts of patients treated with ABA were pooled. Kaplan-Meier analysis was used to compare drug retention across registries. Specific causes of drug retention were investigated using competing risks multivariate Cox regression. Results A total of 3961 patients treated with ABA, with 6188 patient-years of follow-up, were included. Patients in the different national registries had similar demographic features, but varied in baseline disease characteristics. ABA drug retention differed between countries, with median drug retention rates ranging from 1.2 to more than 6 years. The differences in drug retention were marginally explained by disparities in disease characteristics, while the national GDP per capita was strongly associated with drug retention (correlation coefficient −0.74; p=0.02). Conclusions Patient characteristics at ABA initiation vary across Europe, probably reflecting differences in eligibility criteria and prescription patterns. However, the difference in ABA drug retention between countries was not primarily explained by disparities in patient characteristics. Lower ABA retention was observed in countries with a more liberal access to bDMARDs and higher GDP. National differences need to be accounted for when pooling data on treatment with bDMARDs from various countries.

Abstract
OBJECTIVES To determine to what extent shared epitopes, smoking, and anti-cyclic citrullinated peptide (anti-CCP) antibodies are associated with disease activity and erosive disease in patients with rheumatoid arthritis (RA) at disease onset. METHOD RA patients not previously treated with disease-modifying anti-rheumatic drugs (DMARDs) and with a disease duration of < 6 months (CIMESTRA study) were examined for shared epitopes, anti-CCP antibodies, immunoglobulin M rheumatoid factor (IgM-RF) and IgA-RF, radiographic erosive changes in hands and feet, and clinical disease activity. RESULTS The study comprised 153 patients, of whom 104 (68%) were ever-smokers. The prevalence of patients with 0, 1, or 2 shared epitopes was 40 (48%), 71 (49%), and 33 (23%), respectively. Anti-CCP antibodies, IgM-RF, and IgA-RF were present in 89 (58%), 99 (65%), and 82 (54%) patients, respectively. Among smokers, erosive disease was associated with anti-CCP antibodies [odds ratio (OR) 3.9, 95% confidence interval (CI) 1.6-9.3], IgM-RF (OR 4.9, 95% CI 1.9-12), and IgA-RF (OR 2.8, 95% CI 1.2-6.4) but absent with regard to shared epitopes. Among never-smokers, erosive disease was not associated with either shared epitopes or antibodies. All antibody levels measured were associated with smoking and shared epitopes. CONCLUSIONS Shared epitopes and smoking were associated with the production of anti-CCP antibodies and rheumatoid factors of IgM and IgA isotypes, which again were associated with erosive disease at presentation only in smokers. As shared epitopes and smoking were not directly associated with erosive disease, smoking may enhance the development of erosive disease in RA at different levels or through separate pathways.

Abstract
OBJECTIVES Advances in aggressive use of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) as well as biological DMARDs (bDMARDs) have improved the treatment armamentarium for rheumatologists, and modern treatment principles include a treat-to-target (T2T) strategy. However, little is known about the feasibility of a T2T strategy in patients with rheumatoid arthritis (RA) treated in routine care. The aim of the present study was to (i) present the annual number of patients included in DANBIO between 2006 and 2013 and their disease characteristics and (ii) estimate coverage of DANBIO by 2013. METHODS Patients who were registered with RA for the first time in the nationwide Danish DANBIO database between year 2006 and 2013 were included. Baseline characteristics were assessed in patients treated with bDMARDs and csDMARDs, respectively. The fraction of patients with low/moderate/high disease activity (i.e. DAS28 (CRP-based, 4 variables) was calculated for each calendar year. RESULTS From 2006-2013 the number of patients increased from 2,395 to 14,249. By 2013, 29.8% of patients were receiving bDMARD. Patients in the csDMARD group were older, had shorter disease duration, lower disease activity, less disability and radiographic damage. By 2013, 19% of csDMARD (15% of bDMARD) patients were in ACR/Boolean remission. Coverage had increased to between 41% and 79% for patients with RA, for the bDMARD group it was 94%. CONCLUSIONS Systematic monitoring of RA patients with real-time feedback to the physician is feasible, although the goal of treat-to-target is not achieved in a substantial proportion of patients in routine care.

Abstract
OBJECTIVES Programmed death-1 (PD-1) is an immunoregulatory molecule functioning by down-regulating immune responses. PD-1 is present on follicular helper T cells (TFH) and is important in the formation of plasma cells. PD-1 exists in a bioactive soluble form (sPD-1) and is thought to be implicated in disease activity in chronic rheumatoid arthritis (RA). METHOD We measured sPD-1 at baseline and 9 months after treatment initiation in plasma from early RA patients (n = 34). We tested for correlations with the Disease Activity Score using 28 joint counts (DAS28), the Health Assessment Questionnaire (HAQ) score, immunoglobulin M rheumatoid factor (IgM-RF), anti-cyclic citrullinated peptide (anti-CCP) antibodies, C-reactive protein (CRP), interleukin-21 (IL-21), and total Sharp score (TSS). We also measured sPD-1 in plasma from healthy volunteers (HV) (n = 20) and in plasma and synovial fluid (SF) from patients with chronic RA (> 8 years of disease, n = 30). We further investigated the cellular expression of PD-1 and its ligand PD-L1. RESULTS sPD-1 concentrations in early [median 0.421 ng/mL, interquartile range (IQR) 0.04-2.560 ng/mL] and chronic (median 0.239 ng/mL, IQR 0.184-0.584 ng/mL) RA were increased compared with HV (median 0.04 ng/mL, IQR 0.04-0.04 ng/mL) (all p < 0.005). In early RA the change in sPD-1 was associated with DAS28 (r = 0.363, p < 0.05) and HAQ score (r = 0.554, p < 0.05) and inversely with TSS at 3-5 years (r = -0.468, p < 0.05). sPD-1 concentration correlated with IgM-RF, anti-CCP antibodies, and IL-21 (all p < 0.05). PD-1 was primarily expressed by synovial memory T cells whereas PD-L1 was mainly expressed by synovial monocytes. CONCLUSIONS The significantly elevated plasma levels of sPD-1 in early RA, the association with core disease parameters, and the inverse correlation with TSS suggest that sPD-1 is an important mediator in inflammatory and radiographic disease progression.

Abstract
OBJECTIVES To study the CD26 density on monocytes and CD4+ T-lymphocytes in steroid and DMARD-naïve, early rheumatoid arthritis (RA) patients and to analyse for correlations with disease activity, including long-term radiographic progression. METHODS Forty patients with active, early steroid and DMARD naïve RA (<6 months' duration) were randomised to treatment with methotrexate (MTX) versus MTX and cyclosporine A (CYA). Controls were 15 healthy age and gender matched subjects. Peripheral blood mononuclear cells were analysed for CD26 density by flow cytometry at baseline and after 52 weeks. Radiographic progression was scored by delta total Sharp-van der Heijde score (TSS) from 0 to 5 years. RESULTS The density of CD26 on monocytes (CD3-CD14+) in RA was up-regulated compared to healthy controls (p<0.0001) and remained unaffected by clinically effective DMARD treatment after 52 weeks. In anti-CCP positive RA patients (n=18) baseline CD26 density on monocytes correlated to 5-year radiographic progression (p=0.008, r=0.60). The density of CD26 did not correlate to DAS28, the swollen or tender joint count or CRP-level at baseline or at year one. The CD26 density on CD4+ T-lymphocytes at week 0 was comparable to healthy controls (p=0.34). CONCLUSIONS The up-regulated density of CD26 on monocytes in steroid and DMARD naïve active early RA was unaffected by 52 weeks of effective DMARD treatment and correlated to 5-year radiographic progression.

Abstract
OBJECTIVES To investigate the expression of the soluble form of the resident macrophage marker CD163 (sCD163) and its association with core parameters for disease activity, including radiographic progression in early rheumatoid arthritis (RA). METHODS In a longitudinal sample set from early RA patients (n=34) we measured plasma levels of sCD163 at initiation of treatment and after 9 months of treatment and correlated levels with disease activity in 28 joints (DAS28), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and total Sharp score (TSS). We also measured plasma levels of sCD163 in 55 healthy volunteers (HV) and in a transverse sample set of chronic (>8 years of disease) RA patients (n=24) and OA patients (n=24) with paired plasma and joint fluid. RESULTS Early RA patients had significantly higher plasma levels of sCD163 (1.69mg/l (1.42-2.10)) (median (IQR)) at baseline than after 9 months of treatment (1.28mg/l (0.963-1.66), p=0.001), but not significantly changed compared with HV (1.66mg/l (1.22-2.02)). In early RA patients, baseline levels of sCD163, correlated with DAS28, CRP and ESR. Interestingly, sCD163 at 9 months was associated with radiographic progression (TSS) between year 0 and 5 (r=0.468, p=0.02). Levels of sCD163 were higher in RA patients, than in OA patients and higher in SF than in plasma. CONCLUSIONS Plasma levels of macrophage derived sCD163 are associated with disease activity and predict radiographic progression in early RA patients, supporting that sCD163 may have a role as a biomarker of disease activity and that resident macrophages are important for joint destruction.

Abstract
OBJECTIVES To analyse clinical severity/activity of rheumatoid arthritis (RA) according to smoking status. METHODS The QUEST-RA multinational database reviews patients for Core Data Set measures including 28 swollen and tender joint count, physician global estimate, erythrocyte sedimentation rate (ESR), HAQ-function, pain, and patient global estimate, as well as DAS28, rheumatoid factor (RF), nodules, erosions and number of DMARDs were recorded. Smoking status was assessed by self-report as 'never smoked', 'currently smoking' and 'former smokers'. Patient groups with different smoking status were compared for demographic and RA measures. RESULTS Among the 7,307 patients with smoking data available, status as 'never smoked,' 'current smoker' and 'former smoker' were reported by 65%, 15% and 20%. Ever smokers were more likely to be RF-positive (OR 1.32;1.17-1.48, p<0.001). Rheumatoid nodules were more frequent in ever smokers (OR 1.41;1.24-1.59, p<0.001). The percentage of patients with erosive arthritis and extra-articular disease was similar in all smoking categories. Mean DAS28 was 4.4 (SD 1.6) in non-smokers vs. 4.0 (SD 1.6) in those who had ever smoked. However, when adjusted by age, sex, disease duration, and country gross domestic product, only ESR remained significantly different among Core Data Set measures (mean 31.7mm in non-smokers vs. 26.8mm in ever smoked category). CONCLUSIONS RA patients who had ever smoked were more likely to have RF and nodules, but values for other clinical status measures were similar in all smoking categories (never smoked, current smokers and former smokers).

Abstract
OBJECTIVES To assess the drug survival and reasons for discontinuation of intramuscular methotrexate (imMTX) in rheumatological patients who had switched to imMTX from oral methotrexate (oMTX). METHODS Data from 212 consecutive patients who switched from oMTX to imMTX therapy at our outpatient clinic between April 1997 and January 2004 were collected retrospectively through survey of case records. Data included reason for discontinuation of oMTX, disease activity parameters, duration of imMTX therapy, and, in patients who withdrew, the reason for discontinuation of imMTX. RESULTS The main reasons for switching from oMTX to imMTX were lack of efficacy (66%) and adverse events (28%). After 6 months, 114 patients (54%) were still receiving imMTX therapy, and their median serum C-reactive protein (CRP) and the percentage of patients who had received glucocorticoids during the previous 6 weeks had decreased (p<0.001). The median survival of imMTX therapy was 7.5 months (interquartile range 3-17). Twenty per cent of the patients received imMTX for more than 24 months. Of the 212 patients, 41% and 9% stopped imMTX therapy because of lack of efficacy and adverse events, respectively. Of the patients who had stopped oMTX because of adverse events, 22% also withdrew from imMTX because of adverse events. CONCLUSION Half of the patients benefited from switching from oral to intramuscular methotrexate for at least 6 months, but only a minority adhered to the treatment for years. Lack of efficacy was the most frequent reason for discontinuation, while adverse events were rare.

Abstract
OBJECTIVE To analyse associations between the clinical status of patients with rheumatoid arthritis (RA) and the gross domestic product (GDP) of their resident country. METHODS The Quantitative Standard Monitoring of Patients with Rheumatoid Arthritis (QUEST-RA) cohort includes clinical and questionnaire data from 6004 patients who were seen in usual care at 70 rheumatology clinics in 25 countries as of April 2008, including 18 European countries. Demographic variables, clinical characteristics, RA disease activity measures, including the disease activity score in 28 joints (DAS28), and treatment-related variables were analysed according to GDP per capita, including 14 "high GDP" countries with GDP per capita greater than US$24,000 and 11 "low GDP" countries with GDP per capita less than US$11,000. RESULTS Disease activity DAS28 ranged between 3.1 and 6.0 among the 25 countries and was significantly associated with GDP (r = -0.78, 95% CI -0.56 to -0.90, r(2) = 61%). Disease activity levels differed substantially between "high GDP" and "low GDP" countries at much greater levels than according to whether patients were currently taking or not taking methotrexate, prednisone and/or biological agents. CONCLUSIONS The clinical status of patients with RA was correlated significantly with GDP among 25 mostly European countries according to all disease measures, associated only modestly with the current use of antirheumatic medications. The burden of arthritis appears substantially greater in "low GDP" than in "high GDP" countries. These findings may alert healthcare professionals and designers of health policy towards improving the clinical status of patients with RA in all countries.

Abstract
BACKGROUND Prescription practice for tumour necrosis factor alpha (TNFalpha) inhibitors has changed towards treating patients with lower disease activity. OBJECTIVE To determine the trend in treatment response in cohorts of patients with rheumatoid arthritis who started TNFalpha inhibitor treatment between 2000 and 2005. METHODS 1813 patients with RA starting treatment with biological agents in 2000-5 were registered prospectively in the nationwide DANBIO Registry. Baseline disease activity and 12 months' treatment responses were determined in cohorts based on start year (2000/1; 2002; 2003; 2004; 2005). RESULTS Despite decreasing baseline disease activity from the 2000/2001 cohort to 2005 cohort (28-joint count Disease Activity Score (DAS28): from 5.9 to 5.3 (p<0.001)), the 12 months' DAS improvement increased from 1.8 units (2000/2001 cohort) to 2.2 units (2005 cohort) (p<0.001). The fraction with good EULAR response increased from 28% (2000/2001 cohort) to 50% (2005 cohort); the fraction with no response decreased from 29% (2000/2001 cohort) to 16% (2005 cohort). ACR20/50/70 response rates increased from 53%/31%/13% (2000/2001 cohort) to 69%/51%/30% (2005 cohort). After correction for withdrawals, treatment responses were lower, but patterns unchanged. One-year drug survival was for the 2000/2001 cohort: 73%, 2002: 62%, 2003: 67%, 2004: 70%, 2005: 69%. CONCLUSION From 2000 to 2005, significantly improved treatment responses to TNF inhibitors were seen in clinical practice despite decreasing baseline disease activity levels. This lends support to the less stringent prescription practice towards treating patients with lower disease activity that has been observed in several countries.

Abstract
OBJECTIVES To compare the ability of two different dedicated extremity MRI (E-MRI) units and conventional radiography (CR) for identifying bone erosions in rheumatoid arthritis (RA) metacarpophalangeal (MCP) and wrist joints. METHODS CR and two MRI examinations (using 0.2 T Esaote Artoscan and 0.2 T portable MagneVu MV1000 units) of 418 bones in the dominant wrist and second to fifth MCP joints of 15 patients with RA and 4 healthy controls were performed and evaluated blindly for bones being visible and for erosions. RESULTS In MCP joints, MagneVu visualised 18.5% of bones entirely and 71.1% were 67-99% visualised. In wrists, MagneVu visualised 1.5% of bones entirely, 39.8% were 67-99% visualised and 19% were not visualised at all. Artoscan and CR visualised all bones entirely. Artoscan, MagneVu and CR found 22, 19 and 15 bones with erosions in MCP joints and 66, 40 and 13 bones with erosions in wrist joints, respectively. With the previously validated Artoscan unit as standard reference, MagneVu and CR had sensitivities of 0.82 and 0.55, respectively, in MCP joint bones and 0.41 and 0.14 in wrist bones. Specificities of CR and MagneVu were comparable (0.82-0.99). The MagneVu unit was particularly more sensitive than CR for metacarpal heads and carpal bones. MagneVu MRI and CR detected 100% and 89%, respectively, of large erosions (Outcome Measures in Rheumatoid Arthritis Clinical Trials-Rheumatoid Arthritis MRI Scoring System (OMERACT-RAMRIS) score >1 on Artoscan) in MCP joints and 69% and 15.8% of large erosions in wrists. CONCLUSIONS Both E-MRI units detected more erosions than CR, in particular due to a higher sensitivity in metacarpal heads and carpal bones. The MagneVu unit detected fewer erosions than the Artoscan unit due to a lower average image quality and a smaller proportion of bones being visualised.

Abstract
OBJECTIVE To investigate whether clinical and radiographic disease control can be achieved and maintained in patients with early, active rheumatoid arthritis (RA) during the second year of aggressive treatment with conventional disease-modifying antirheumatic drugs (DMARDs) and intra-articular corticosteroid. This paper presents the results of the second year of the randomised, controlled double-blind CIMESTRA (Ciclosporine, Methotrexate, Steroid in RA) study. METHODS 160 patients with early RA (duration <6 months) were randomised to receive intra-articular betamethasone in any swollen joint in combination with step-up treatment with either methotrexate and placebo-ciclosporine (monotherapy) or methotrexate plus ciclosporine (combination therapy) during the first 76 weeks. At week 68 hydroxychlorochine 200 mg daily was added. From week 76-104 ciclosporine/placebo-ciclosporine was tapered to zero. RESULTS American College of Rheumatology 20% improvement (ACR20), ACR50 and ACR70 levels were achieved in 88%, 79% and 59% of patients in the combination vs 72%, 62% and 54% in the monotherapy group (p = 0.03, 0.02 and 0.6 between groups). The patients globally declined from 50 to 12 vs 52 to 9, with 51% and 50% in Disease Activity Score (DAS) remission, respectively. Mean (SD) progressions in total Sharp-van der Heijde scores were 1.42 (3.52) and 2.03 (5.86) in combination and monotherapy groups, respectively (not significant). Serum creatinine levels increased by 7% in the combination group (4% in monotherapy), but hypertension was not more prevalent. CONCLUSION Continuous methotrexate and intra-articular corticosteroid treatment resulted in excellent clinical response and disease control at 2 years, and the radiographic erosive progression was minimal. Addition of ciclosporine during the first 76 weeks resulted in significantly better ACR20 and ACR50 responses, but did not have any additional effect on remission rate and radiographic outcome.

Abstract
Since the year 2000, Danish rheumatologists have been collecting data on a routine basis in the nationwide DANBIO registry, which includes all rheumatologic patients receiving biological drugs. Demographic data, markers of disease activity, current treatment, serious and non-serious adverse events and reasons for discontinuation are registered at each visit either on paper forms or on-line. By June 2005, approximately 3000 treatment courses (18,000 visits) were in the registry, corresponding to close to 90% of eligible patients. Rheumatoid arthritis was the most prevalent diagnosis (75%) followed by ankylosing spondylitis (11%) and psoriatic arthritis (7%). Infections occurred in 43% of the treatment series.

Abstract
OBJECTIVE To present from the Danish Database for Biological Therapies in Rheumatology (DANBIO) the frequencies and types of adverse events as well as risk factors during treatment with biological agents in clinical practice. METHODS Adverse events during the first 2 years of clinical use of biological agents in Denmark were reported to the nationwide DANBIO and compared to the mandatory reports to the Danish Medicines Agency. RESULTS Almost 90% of the patients treated with biological agents were registered in the DANBIO, and the database picked up 20 times as many adverse events as the Danish Medicines Agency. Infections and hypersensitivity reactions were the most prevalent adverse events. Age, disease duration, and previous number of disease-modifying anti-rheumatic drugs (DMARDS) were found to be risk factors for bacterial infections. CONCLUSION A routine-based Danish database for biological therapies covers approximately 90% of patients and improves the reporting of adverse events.

Abstract
BACKGROUND The study was based on the Danish DANBIO and the Norwegian NOR-DMARD databases. OBJECTIVE To investigate changes in prescription practice during the first 3 years of post-marketing use of biological drugs, and to determine the proportion of patients who would not have received tumour necrosis factor (TNF) blocking agents if the prescription guidelines of the UK and the Netherlands had been applied. METHODS Patients with rheumatoid arthritis (RA) receiving TNF blocking agents from Denmark (n = 823, median age 56.0, 72.2% women) and Norway (n = 371, median age 52.5, 75.4% women) were studied. Prescription guidelines in the UK and the Netherlands were applied to the data. RESULTS Baseline disease activity and number of previous DMARDs declined significantly during the 3 years (median baseline DAS28 decreased from 5.8 to 5.2 in Denmark (p<0.001) and from 6.0 to 5.6 in Norway (p<0.01)). 47.9% and 41.3% of the Norwegian and Danish patients, respectively, did not meet the UK criteria for using TNF blocking agents, and 10.5% and 5.7% did not meet the Dutch criteria. CONCLUSION Danish and Norwegian prescription practices of biological treatments in RA were similar, and became less stringent from 2000 to 2003. Prescriptions agreed well with the Dutch guidelines, but almost half the patients did not meet the UK guidelines.
