Abstract
BACKGROUND Even after the approval of tocilizumab, substantial glucocorticoid exposure (usually ≥6 months) and toxicity continue to be important problems for patients with giant cell arteritis. We aimed to assess the outcomes of a group of patients with giant cell arteritis treated with tocilizumab in combination with 8 weeks of prednisone. METHODS This prospective, single arm, proof-of-concept study was conducted at Massachusetts General Hospital (Boston, MA, USA). Individuals aged 50 years or older who had new-onset or relapsing giant cell arteritis with active disease were eligible for inclusion. Participants received 12 months of tocilizumab 162 mg weekly subcutaneously in combination with 8 weeks of prednisone. The primary endpoint was sustained prednisone-free remission at week 52. Adverse events were also evaluated. This trial is registered with ClinicalTrials.gov (NCT03726749), and is complete. FINDINGS Between Nov 28, 2018, and Nov 2, 2020, we enrolled 30 patients (mean age 73·7 years [SD 8·1], 18 [60%] women and 12 [40%] men, 30 [100%] White race, 15 [50%] new-onset disease, 23 [77%] temporal artery biopsy-proven, 14 [47%] imaging-proven). The initial prednisone doses were 60 mg (n=7), 50 mg (n=1), 40 mg (n=7), 30 mg (n=6), and 20 mg (n=9). All patients entered remission within 4 weeks from baseline. 23 (77%) of 30 patients were in sustained prednisone-free remission at week 52 and seven (23%) patients relapsed, with a mean time to relapse of 15·8 weeks (SD 14·7). Overall, four (13%) participants developed a serious adverse event, including one related or probably related to prednisone exclusively, two related or probably related to tocilizumab exclusively, and one related or probably related to prednisone, tocilizumab, or both. Two of the non-responder patients stopped tocilizumab and withdrew from the study prematurely after having a second disease relapse. No cases of giant cell arteritis-related permanent vision loss occurred during the study. INTERPRETATION These results suggest that 12 months of tocilizumab in combination with 8 weeks of prednisone could induce and maintain remission in patients with giant cell arteritis. Confirmation of these findings in a randomised controlled trial is required. FUNDING Genentech.

Abstract
BACKGROUND More than half of patients with polymyalgia rheumatica have a relapse during tapering of glucocorticoid therapy. Previous studies have suggested that interleukin-6 blockade may be clinically useful in the treatment of polymyalgia rheumatica. Sarilumab, a human monoclonal antibody, binds interleukin-6 receptor α and efficiently blocks the interleukin-6 pathway. METHODS In this phase 3 trial, we randomly assigned patients in a 1:1 ratio to receive 52 weeks of a twice-monthly subcutaneous injection of either sarilumab (at a dose of 200 mg) plus a 14-week prednisone taper or placebo plus a 52-week prednisone taper. The primary outcome at 52 weeks was sustained remission, which was defined as the resolution of signs and symptoms of polymyalgia rheumatica by week 12 and sustained normalization of the C-reactive protein level, absence of disease flare, and adherence to the prednisone taper from weeks 12 through 52. RESULTS A total of 118 patients underwent randomization (60 to receive sarilumab and 58 to receive placebo). At week 52, sustained remission occurred in 28% (17 of 60 patients) in the sarilumab group and in 10% (6 of 58 patients) in the placebo group (difference, 18 percentage points; 95% confidence interval, 4 to 32; P = 0.02). The median cumulative glucocorticoid dose at 52 weeks was significantly lower in the sarilumab group than in the placebo group (777 mg vs. 2044 mg; P<0.001). The most common adverse events with sarilumab as compared with placebo were neutropenia (15% vs. 0%), arthralgia (15% vs. 5%), and diarrhea (12% vs. 2%). More treatment-related discontinuations were observed in the sarilumab group than in the placebo group (12% vs. 7%). CONCLUSIONS Sarilumab showed significant efficacy in achieving sustained remission and reducing the cumulative glucocorticoid dose in patients with a relapse of polymyalgia rheumatica during glucocorticoid tapering.

Abstract
OBJECTIVE To develop the first evidence-based Pan American League of Associations for Rheumatology (PANLAR) guidelines for the treatment of Takayasu arteritis (TAK). METHODS A panel of vasculitis experts developed a series of clinically meaningful questions addressing the treatment of TAK patients in the PICO (population/intervention/comparator/outcome) format. A systematic literature review was performed by a team of methodologists. The evidence quality was assessed according to the GRADE (Grading of Recommendations/Assessment/Development/Evaluation) methodology. The panel of vasculitis experts voted each PICO question and made recommendations, which required ≥70% agreement among the voting members. RESULTS Eleven recommendations were developed. Oral glucocorticoids are conditionally recommended for newly diagnosed and relapsing TAK patients. The addition of nontargeted synthetic immunosuppressants (e.g., methotrexate, leflunomide, azathioprine, or mycophenolate mofetil) is recommended for patients with newly diagnosed or relapsing disease that is not organ- or life-threatening. For organ- or life-threatening disease, we conditionally recommend tumor necrosis factor inhibitors (e.g., infliximab or adalimumab) or tocilizumab with consideration for short courses of cyclophosphamide as an alternative in case of restricted access to biologics. For patients relapsing despite nontargeted synthetic immunosuppressants, we conditionally recommend to switch from one nontargeted synthetic immunosuppressant to another or to add tumor necrosis factor inhibitors or tocilizumab. We conditionally recommend low-dose aspirin for patients with involvement of cranial or coronary arteries to prevent ischemic complications. We strongly recommend performing surgical vascular interventions during periods of remission whenever possible. CONCLUSION The first PANLAR treatment guidelines for TAK provide evidence-based guidance for the treatment of TAK patients in Latin American countries.

Abstract
Prolonged glucocorticoid tapers have been the standard of care for giant cell arteritis (GCA) and polymyalgia rheumatica (PMR), but recent advancements have improved outcomes for patients with GCA while reducing glucocorticoid-related toxicities. Many patients with GCA and PMR still experience persistent or relapsing disease, and cumulative exposure to glucocorticoids for both diseases remains high. The objective of this review is to define current treatment approaches as well as new therapeutic targets and strategies. Studies investigating inhibition of cytokine pathways, including interleukin-6, interleukin-17, interleukin-23, granulocyte-macrophage colony-stimulating factor, Janus kinase-signal transduction and activator of transcription, and others, will be reviewed.

Abstract
Considerable variability exists in the way health-care providers treat patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis in Latin America. The most frequently used treatments for ANCA-associated vasculitis are cyclophosphamide and prolonged glucocorticoid tapers; however, randomised controlled trials conducted over the past 30 years have led to the development of several evidence-based treatment alternatives for these patients. Latin America faces socioeconomic challenges that affect access to care, and the use of certain costly medications with proven efficacy ANCA-associated vasculitis is often restricted. For these reasons, the Pan American League of Associations for Rheumatology developed the first ANCA-associated vasculitis treatment guidelines tailored for Latin America. A panel of local vasculitis experts generated clinically meaningful questions related to the treatment of ANCA-associated vasculitis using the Population, Intervention, Comparator, and Outcome (PICO) format. Following the Grading of Recommendations Assessment, Development, and Evaluation methodology, a team of methodologists conducted a systematic literature review. The panel of vasculitis experts voted on each PICO question and made recommendations, which required at least 70% agreement among the voting members. 21 recommendations and two expert opinion statements for the treatment of ANCA-associated vasculitis were developed, considering the current evidence and the socioeconomic characteristics of the region. These recommendations include guidance for the use of glucocorticoids, non-glucocorticoid immunosuppressants, and plasma exchange.

Abstract
Considerable variability exists in the way that health-care providers treat patients with giant cell arteritis in Latin America, with patients commonly exposed to excessive amounts of glucocorticoids. In addition, large health disparities prevail in this region due to socioeconomic factors, which influence access to care, including biological treatments. For these reasons, the Pan American League of Associations for Rheumatology developed the first evidence-based giant cell arteritis treatment guidelines tailored for Latin America. A panel of vasculitis experts from Mexico, Colombia, Peru, Brazil, and Argentina generated clinically meaningful questions related to the treatment of giant cell arteritis in the population, intervention, comparator, and outcome (PICO) format. Following the grading of recommendations, assessment, development, and evaluation methodology, a team of methodologists did a systematic literature search, extracted and summarised the effects of the interventions, and graded the quality of the evidence. The panel of vasculitis experts voted on each PICO question and made recommendations, which required at least 70% agreement among the voting members to be included in the guidelines. Nine recommendations and one expert opinion statement for the treatment of giant cell arteritis were developed considering the most up-to-date evidence and the socioeconomic characteristics of Latin America. These recommendations include guidance for the use of glucocorticoids, tocilizumab, methotrexate, and aspirin for patients with giant cell arteritis.

Abstract
BackgroundData on the long-term efficacy and safety of tocilizumab (TCZ) for giant cell arteritis (GCA), including incidence and timing of disease relapse after TCZ discontinuation, is limited.ObjectivesWe aimed to evaluate the long-term outcomes of GCA patients treated with TCZ in a real-world setting.MethodsRetrospective analysis of GCA patients treated with TCZ for >9 months at a single center between 2010-2021. Time to relapse and annualized relapse rate during and after TCZ treatment, prednisone use and safety were assessed. Relapse was defined as the re-appearance of clinical manifestations of GCA that required treatment intensification regardless of the erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) levels. The duration of TCZ treatment was determined as per the best clinical judgement of the treating rheumatologist.ResultsA total of 57 GCA patients were followed for a mean (SD) period of 3.4 (1.7) years. Baseline characteristics and treatments received are shown in Table 1. Patients were maintained on their initial TCZ course for a mean (SD) period of 2.0 (1.3) years. The initial TCZ course lasted >12 months in 50 (88%) patients. During the initial TCZ course, 8 (14.0%) patients relapsed. Kaplan-Meier (KM) estimated relapse rates on TCZ were 10.5% and 14.9% at 12 and 18 months, respectively (Figure 1A). TCZ was discontinued due to long-term remission in 37 (64.9%) patients and after an adverse event in 6 (10.5%) patients. Of the 43 patients stopping TCZ due to remission or adverse event, 19 (44.2%) subsequently relapsed. KM estimated relapse rates after TCZ discontinuation were 30.4% and 44.0% at 12 and 18 months, respectively (Figure 1B). Overall, 12 patients received more than one TCZ course. The aggregation of all TCZ courses (mean 2.5 years) and all periods off TCZ following the initial TCZ treatment (mean 0.9 years) showed that 11 (19.3%) patients relapsed while on TCZ and 20 (35.1%) patients relapsed during time off TCZ. An analysis adjusting for age, sex, prednisone dose at initiation of first TCZ course, and disease type (new onset vs. relapsing) at initiation of first TCZ course showed an annualized relapse rate (95% CI) of 0.1 (0.0-0.2) during TCZ treatment and 0.4 (0.3-0.7) off TCZ (rate ratio 0.2, p<0.0001). By the end of follow up, 42 (73.7%) patients were able to wean off prednisone. During the study, 12 serious adverse events occurred in 11 (19.3%) patients. Among those 12 events, 3 (25%) were related or possibly related to TCZ exclusively (i.e., soft tissue infection, bacteremia, and COVID-19), 3 (25%) to prednisone exclusively (i.e., osteoporotic fracture, diabetic ketoacidosis and stroke), and 2 (16.7%) to either TCZ or prednisone (i.e., pneumonia and sepsis).Table 1.Baseline characteristics and treatmentsGCA patients(n = 57)Age, mean (SD)70.1 (9.3)Female sex39 (68.4)New onset disease at TCZ initiation18 (31.6)Initial TCZ treatment 4 mg/Kg intravenously monthly2 (3.5) 8 mg/Kg intravenously monthly13 (22.8) 162 mg subcutaneously every 2 weeks6 (10.5) 162 mg subcutaneously weekly36 (63.2)On prednisone at TCZ initiation57 (100)Prednisone dose (mg) at TCZ initiation, mean (SD)32.3 (21.7)Patients receiving >1 TCZ course12 (21.1)Duration of initial TCZ course (years), mean (SD)2.0 (1.3)Total duration of TCZ treatment (years), mean (SD)2.5 (1.6)*Values represent number and (%) unless otherwise specified. *Aggregated time on tocilizumab (TCZ)for those patients that received more than 1 TCZ course.

Abstract
BackgroundEven with the use of tocilizumab (TCZ), significant glucocorticoid exposure (usually ≥ 6 months) continues to be an important problem in giant cell arteritis (GCA).ObjectivesWe aimed to evaluate the efficacy and safety of tocilizumab (TCZ) in combination with 2 months of prednisone in a group of patients with GCA.MethodsWe conducted a prospective, single arm, open-label study of TCZ in combination with 2 months of prednisone for new-onset and relapsing GCA patients with active disease (ClinicalTrials.gov Identifier NCT03726749). GCA diagnosis required confirmation by temporal artery biopsy or vascular imaging. Active disease was defined as presence of cranial or polymyalgia rheumatica symptoms necessitating treatment within 6 weeks of baseline. All patients received TCZ 162 mg subcutaneously every week for 12 months and an 8-week prednisone taper starting between 20 mg and 60 mg daily (Figure 1). The primary endpoint, sustained prednisone-free remission, was defined as absence of relapse from induction of remission up to week 52 while adhering to the prednisone taper. Relapse was defined as the recurrence of symptoms of GCA requiring treatment intensification regardless of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels. Safety was also evaluated.Figure 1.Clinical Trial SchemaResultsBetween 11/2018 and 11/2020 we enrolled 30 patients (mean age 74 years, 60% females, 50% new-onset disease, 77% temporal artery biopsy-proven, 47% imaging-proven). The mean ESR and CRP at screening were 45 mm/hour and 48 mg/L, respectively. The initial prednisone dose was 60 mg (n = 7), 50 mg (n = 1), 40 mg (n = 7), 30 mg (n = 6) and 20 mg (n = 9). All patients entered remission within 4 weeks of baseline. The primary endpoint was achieved by 23 (77%) patients (Table 1). The mean (SD) cumulative prednisone dose in these 23 patients was 1052 (390) mg. After a mean period of 16 weeks, 7 (23%) patients relapsed (Table 1). All relapses but one occurred after the completion of the study prednisone taper. Overall, 6 of the 7 patients with relapse received a second prednisone taper over 8 weeks. Of these 6 patients, 4 achieved and maintained remission for the remainder of the trial period, and 2 withdrew from the study after having a second relapse. One patient with relapse received a second prednisone taper over 26 weeks and stayed in remission until the end of the study. The mean (SD) cumulative prednisone dose in the 7 patients with relapse was 1883 (699) mg (Table 1). Overall, 4 (13%) participants developed a serious adverse event (Table 1). No cases of ischemia-related visual symptoms including permanent vision loss occurred during the study.Table 1.Efficacy and Safety OutcomesGCA patients(n = 30)Efficacy Sustained, prednisone-free remission by week 5223.0 (76.7) Cumulative prednisone dose (mg) at week 52, mean (SD)1051.5 (390.3) Relapse7.0 (23.3) Time to relapse, weeks: mean (SD)15.8 (14.7) Prednisone dose (mg/day) at relapse, mean (SD)2.1 (5.2) Cumulative prednisone dose (mg), mean (SD)1883.1 (699.2) Clinical manifestations at relapse Cranial symptoms4 out of 7 patients Ischemic visual symptoms0 out of 7 patients PMR symptoms4 out of 7 patientsSafety Serious adverse events4.0 (13.3) Cellulitis1 COVID-191 Fragility fracture1 Cholecystitis1Values represent number and (%) unless otherwise specified.

Abstract
BACKGROUND Despite appropriate use of corticosteroids, an important minority of patients with giant cell arteritis (GCA) develop progressive vision loss during the initial stages of the disease or during corticosteroid tapering. Tocilizumab is the only clearly effective adjunctive treatment to corticosteroids in the management of GCA, but questions regarding its efficacy specifically in the neuro-ophthalmic population and its role in mitigating vision loss have not been broached until recently. EVIDENCE ACQUISITION The authors queried Pubmed using the search terms "GCA" and "tocilizumab" in order to identify English-language publications either explicitly designed to evaluate the influence of tocilizumab on the ophthalmic manifestations of GCA or those which reported, but were not primarily focused on, ophthalmic outcomes. RESULTS Recent retrospective analyses of populations similar to those encountered in neuro-ophthalmic practice suggest that tocilizumab is effective in decreasing the frequency of GCA relapse, the proportion of flares involving visual manifestations of GCA, and the likelihood of permanent vision loss. Data regarding the utility of tocilizumab to curtail vision loss at the time of diagnosis are limited to case reports. CONCLUSIONS Compared with conventional corticosteroid monotherapy, treatment of GCA with both corticosteroids and tocilizumab may decrease the likelihood of permanent vision loss. Further prospective, collaborative investigation between rheumatologists and neuro-ophthalmologists is required to clarify the ophthalmic and socioeconomic impact of tocilizumab on the treatment of GCA.

Abstract
BackgroundInterleukin-6 (IL-6) is elevated in patients with active polymyalgia rheumatica (PMR) and is associated with disease activity, relapse and severity. Clinical trials with IL-6 receptor (IL-6R) inhibitors in PMR showed higher remission rates and reduced glucocorticoid (GC) use vs GC alone.1-4ObjectivesThe SAPHYR study (NCT03600818) assessed the efficacy and safety of sarilumab (SAR), a fully human anti IL-6Rα monoclonal antibody, with a 14 week (wk) GC taper in patients with steroid resistant active PMR who flared on ≥7.5 mg/day prednisone or equivalent.MethodsPatients were randomized (1:1) to 52 wks of treatment with SAR 200 mg every 2 wks (Q2W) + 14 wk GC tapered regimen (SAR arm) OR placebo Q2W + 52 wk GC tapered regimen (comparator arm). The primary endpoint was the proportion of patients achieving sustained remission at wk 52, defined as disease remission by wk 12, absence of disease flare, CRP normalization from wks 12 to 52 and adherence to the per protocol GC taper from wks 12 to 52.ResultsThe study was terminated early due to protracted recruitment timelines during the COVID-19 pandemic, resulting in 118 of the intended 280 patients recruited between Oct 2018 and Jul 2020, and 117 were treated (SAR n=59, comparator n=58). The demographics were balanced; patients were primarily female, Caucasian, and a median age of ~70 years (Table 1). Overall, 78 patients completed the treatment (SAR n=42; comparator n=36). Primary reasons for treatment discontinuation were adverse events (AEs; SAR n=7, comparator n=4) and lack of efficacy (SAR n=4, comparator n=9). Sustained remission rate was significantly higher in the SAR arm vs the comparator arm (28.3% vs 10.3%; P=0.0193). Results of a sensitivity analysis excluding CRP from the sustained remission definition was consistent with the primary analysis (31.7% vs 13.8%; P=0.0280). All sustained remission components favored SAR (Figure 1). Patients in the SAR arm were 44% less likely to have a flare after achieving clinical remission vs the comparator arm (16.7% vs 29.3%; HR 0.56; 95% CI 0.35–0.90; P=0.0158). The comparator arm required more additional GCs vs the SAR arm, mainly due to PMR flare (median difference in actual and expected cumulative dose 199.5 mg vs 0.0 mg; P=0.0189). The cumulative GC toxicity index scores numerically favored SAR but the difference was not statistically significant. PMR activity scores improved in the SAR arm vs the comparator arm (LS mean -15.57 vs -10.27, nominal P=0.0002). Patient reported outcomes (eg, physical and mental health component scores, disability index, etc) favored SAR (Figure 1). Incidence of treatment-emergent AEs (TEAEs) was numerically higher in the SAR arm vs the comparator arm (94.9% vs 84.5%) and included neutropenia (15.3%) and arthralgia (15.3%) in the SAR arm, and insomnia (15.5%) in the comparator arm. Conversely, the frequency of serious AEs was higher in the comparator arm vs the SAR arm (20.7% vs 13.6%). No deaths were reported.Table 1.Demographics and baseline characteristicsParameterSAR + 14 wk GC taperPlacebo + 52 wk GC taper(n=60)(n=58)Age, median years (range)69 (51–88)70 (52–88)Sex (female), n (%)45 (75.0)37 (63.8)Race, n (%) Caucasian50 (83.3)48 (82.8) Asian1 (1.7)2 (3.4) Not reported9 (15.0)8 (13.8)PMR duration (diagnosis date to baseline),* median days (range)292 (78–3992)310 (66–2784)Any prior disease modifying anti rheumatic drugs, n (%) Methotrexate5 (8.3)10 (17.2) Leflunomide2 (3.3)1 (1.7) Azathioprine01 (1.7) Hydroxychloroquine1 (1.7)1 (1.7) Adalimumab1 (1.7)0 Tocilizumab01 (1.7)CRP (mg/L), median (range)6.8 (0.5–38.2)5.7 (0.1–62.3)Erythrocyte sedimentation rate (mm/h), median (range)25.0 (2.0–115.0)22.0 (5.0–85.0)*SAR n = 54; comparator n= 50.ConclusionSAR + 14 wk GC taper demonstrated significant efficacy vs the comparator arm in steroid refractory PMR patients, including clinically meaningful improvement in quality of life.

Abstract
Background:GiACTA investigated tocilizumab (TCZ) for the treatment of giant cell arteritis (GCA).Objectives:To investigate disease flare characteristics after successful treatment with TCZ in GiACTA.Methods:We report a post hoc analysis from part 2 of GiACTA. Part 1 was a 52-week, double-blind, randomized controlled period and part 2 was a 2-year open-label follow-up. In part 1, patients received TCZ 162 mg subcutaneously every week or every other week with a 26-week prednisone taper or placebo plus a 26- or 52-week prednisone taper. Patients who were in remission at week 52 were to enter part 2 on no TCZ treatment. Part 2 treatment was at the investigator’s discretion. We report characteristics of first disease flare in patients assigned to TCZ in part 1 who were in sustained remission at week 52 and experienced flare in part 2. Flare was defined as reappearance of cranial symptoms (headaches, jaw claudication, visual manifestations, scalp tenderness) or polymyalgia rheumatica (PMR) symptoms or elevation of erythrocyte sedimentation rate (ESR) ≥30 mm/h attributable to GCA that required treatment.Results:Of 149 patients assigned to TCZ in part 1, 81 (54%) were in sustained remission on entering part 2. Of these 81 patients, 37 (46%) experienced at least one flare in part 2, including 17 with new-onset GCA and 20 with relapsing GCA at baseline. Median time to flare was 26.6 weeks. In patients with new-onset GCA, flares included cranial (53%) more often than PMR symptoms (18%). Cranial and PMR symptoms were balanced (both 60%) at the time of flare in patients with relapsing GCA. Visual manifestations occurred in two patients (5%) (Table 1). ESR and CRP were elevated in 65% and 36% of patients, respectively, at the time of flare. Three (8%) flares occurred with elevated ESR without clinical symptoms.Table 1.Clinical manifestations during flare in part 2Part 1 TreatmentaTCZ QW+PredTCZ Q2W+PredAll TCZNew-onset diseasePatients, n281442Patients with ≥1 flare, n (%)b9 (32.1)8 (57.1)17 (40.5)Patients with ESR ≥30 mm/h during flare, n (%)b6 (66.7)6 (75.0)12 (70.6)Patients with CRP ≥10 mg/L during flare, n (%)b4 (44.4)2 (25.0)6 (35.3)Patients with GCA signs or symptoms during flare, n (%)c7 (77.8)7 (87.5)14 (82.4)PMR symptoms1 (11.1)2 (25.0)3 (17.6)Cranial symptomsd4 (44.4)5 (62.5)9 (52.9) Amaurosis fugax000 Blurred vision1 (11.1)01 (5.9) Diplopia000 Blindness000 Ischemic optic neuropathy000Fever1 (11.1)01 (5.9)Othere3 (33.3)2 (25.0)5 (29.4)Relapsing diseasePatients, n281139Patients with ≥1 flare, n (%)b14 (50.0)6 (54.5)20 (51.3)Patients with ESR ≥30 mm/h during flare, n (%)b8 (57.1)4 (66.7)12 (60.0)Patients with CRP ≥10 mg/L during flare, n (%)b5 (35.7)3 (50.0)8 (40.0)Patients with GCA signs or symptoms during flare, n (%)c14 (100)6 (100)20 (100)PMR symptoms8 (57.1)4 (66.7)12 (60.0)Cranial symptomsd8 (57.1)4 (66.7)12 (60.0)Amaurosis fugax1 (7.1)01 (5.0)Blurred vision000Diplopia000Blindness000Ischemic optic neuropathy1 (7.1)01 (5.0)Fever000Othere6 (4.3)1 (16.7)7 (35.0)aPatients from part 1 TCZ+Pred groups who were in sustained remission at week 52 entered part 2 on no treatment.bPercentage based on N in disease-onset group.cPercentage based on number of flare patients in disease-onset group.

Abstract
Background:No universally accepted definition of flare currently exists in giant cell arteritis (GCA). Although relapses are defined mostly on clinical grounds (recurrence of GCA-related signs/symptoms), C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) help clinicians assess disease activity. In fact, >70% of patients on glucocorticoids (GCs) alone have increased CRP or ESR when the disease is active. In contrast, tocilizumab, given its IL-6-blockade effect in the liver, rapidly reduces CRP and ESR levels, rendering them unreliable for disease activity monitoring. Mavrilimumab – a GM-CSF receptor α inhibitor with demonstrated efficacy in a Phase 2 GCA trial1 – downregulates inflammation upstream of IL-6. We hypothesized that mavrilimumab would not interfere with the utility of CRP and ESR in monitoring disease activity and in identifying GCA relapse.Objectives:To analyze the relationship between CRP/ESR and clinical disease activity in GCA patients treated with mavrilimumab.Methods:New-onset and relapsing GCA patients with active disease were recruited. GC-induced remission (no GCA symptoms and CRP <1 mg/dL or ESR <20 mm/hr) was required by baseline. Patients were randomized 3:2 to mavrilimumab 150 mg or placebo subcutaneously every 2 weeks plus a protocol-defined 26-week prednisone taper. The primary efficacy endpoint was time to relapse by Week 26. Relapse (adjudicated) was defined as recurrent GCA-related signs/symptoms, including new/worsening vasculitis on imaging, concurrent with CRP ≥1 mg/dL and/or ESR ≥30 mm/hr. CRP and ESR were also measured periodically during the trial.This post hoc analysis assessed the association of recurrent GCA-related signs/symptoms with concurrent CRP or ESR elevation post-randomization by treatment arm. We also assessed the proportion of patients with CRP or ESR elevation without GCA-related signs/symptoms up to Week 26.Results:Seventy patients were enrolled (mavrilimumab, N=42; placebo, N=28). The association of CRP or ESR elevation with unequivocal GCA-related signs/symptoms post-randomization was consistent regardless of treatment arm: 8/8 in the mavrilimumab group and 13/13 in the placebo group (Table 1). During relapse, median (range) CRP was 1.8 (1.4 – 8.4) mg/dL (mavrilimumab group) and 1.8 (1.1 – 9.0) mg/dL (placebo group). Corresponding ESR values were 39.5 (30 – 102) mm/hr (mavrilimumab group) and 49 (31 – 101) mm/hr (placebo group). Four mavrilimumab recipients had self-limited, equivocal GCA-related signs/symptoms without concurrent CRP or ESR elevation; all 4 completed the prespecified GC taper by Week 26 without need for rescue GCs, so relapse was not confirmed. At least 1 elevated CRP or ESR value in the absence of GCA-related signs/symptoms was observed in 58.8% of mavrilimumab recipients and 93.3% of placebo recipients by Week 26.Conclusion:The observed association of CRP or ESR elevation with GCA-related signs/symptoms is consistent with the upstream mechanism and supports the utility of the stringent protocol definition of relapse. The frequency and magnitude of CRP and ESR elevations at relapse were similar in both treatment groups, suggesting that CRP and ESR remain useful in assessments of disease activity in mavrilimumab-treated patients. CRP and ESR elevations without GCA-related signs/symptoms occurred more often in placebo recipients.References:[1]Cid, Unizony et al.

Abstract
Background:T helper (Th)1 and Th17 lymphocytes play a role in the pathogenesis of giant cell arteritis (GCA). Current treatments primarily target the Th17 axis, possibly leaving residual Th1 activity. Granulocyte macrophage colony stimulating factor (GM-CSF), a mediator of Th1 and Th17 cells, is a pathogenic factor in GCA.Objectives:To evaluate the efficacy and safety of the GM-CSF inhibitor mavrilimumab in patients with GCA.Methods:Randomized, double-blind, placebo-controlled phase 2 trial enrolling patients with active, biopsy- or imaging-proven new onset (N/O) or relapsing refractory (R/R) GCA. Active disease: GCA symptoms and erythrocyte sedimentation rate (ESR) (>30 mm/hr) and/or C-reactive protein (CRP) (≥1 mg/dL) elevation within 6 weeks from randomization. Corticosteroid-induced remission (resolution of GCA symptoms and CRP <1 mg/dL or ESR <20 mm/hr) was required by baseline. 3:2 randomization to mavrilimumab 150 mg or placebo subcutaneously every 2 weeks and protocol-defined 26-week prednisone taper starting at 20-60 mg/day.Primary efficacy endpoint: time to first adjudicated flare (ESR ≥30 mm/hr and/or CRP ≥1 mg/dL and GCA symptoms or new/worsening vasculitis on imaging) by Week 26 in all treated patients. Key secondary endpoint: sustained remission through Week 26. Safety up to Week 38 was assessed.Results:70 patients (35 N/O, 35 R/R) were enrolled (mavrilimumab [N=42] or placebo [N=28]). Mean (SD) age was 69.7 (7.48) years and 71.4% were female. Flare by Week 26 occurred in 8 (19%) and 13 (46.4%) patients receiving mavrilimumab and placebo, respectively (27.4 percentage points reduction). Median time to flare by Week 26 could not be estimated in the mavrilimumab group due to too few events (Not Estimable) and was 25.1 weeks [95% CI: (16.0, NE)] in the placebo group (HR [95% CI] 0.38 [0.15, 0.92]; p=0.0263) (Figure). Sustained remission at Week 26 occurred in 83.2% of patients receiving mavrilimumab and 49.9% of those receiving placebo (33.4 percentage points increase; p=0.0038). Results were consistent across disease type subgroups (HR for flare: N/O 0.29 [95% CI: 0.06, 1.31; nominal p= 0.0873]; R/R 0.43 [95% CI: 0.14, 1.30]; nominal p=0.1231), although not powered for significance (Table). Adverse events (AEs), mostly mild to moderate, were comparable between groups. There were 5 serious AEs (mavrilimumab 2 [4.8%], placebo 3 [10.7%]), none drug-related. No deaths or vision loss occurred. No adjudicated cases of pulmonary alveolar proteinosis were observed.Table 1.Efficacy at Week 26All Patients [1]SubgroupsN/OR/RMavrilimu-mab (N=42)Placebo (N=28)Mavrilimu-mab (N=24)Placebo (N=11)Mavrilimu-mab (N=18)Placebo (N=17)Patients with Flare, n (%)8 (19.0)13 (46.4)3 (12.5)4 (36.4)5 (27.8)9 (52.9)Time to Flare (weeks) [2]Median, 95% CINE (NE, NE)25.1 (16.0, NE)NE (NE, NE)NE (11.7, NE)NE (16.4, NE)22.6 (16.0, NE)HR (Mavrilimumab vs Placebo), 95% CI [3]0.38 (0.15, 0.92)0.29 (0.06, 1.31)0.43 (0.14, 1.30)P-value [4] [5]0.02630.08730.1231Sustained Remission (%), 95% CI [6]83.2 (67.9, 91.6)49.9 (29.6, 67.3)91.3 (69.3, 97.7)62.3 (27.7, 84.0)72.2 (45.6, 87.4)41.7 (17.4, 64.5)Difference in Proportions (95% CI) [7]33.3 (10.7, 55.8)28.9 (-2.7, 60.5)30.6 (-2.1, 63.2)P-value [5] [7]0.00380.07270.0668NE = Not estimable.

Abstract
Background:Acute phase reactants (erythrosedimentation rate [ESR], C-reactive protein [CRP]) have limited utility in GCA, even in patients treated with prednisone alone. Furthermore, the lack of reliable biomarkers in patients receiving interleukin (IL)-6 blockade therapy is a major unmet need.Objectives:To identify biomarkers of disease activity in GCA patients treated with prednisone monotherapy and with prednisone in combination with tocilizumab (TCZ).Methods:We mapped the serum proteome of GCA patients with active and inactive disease in an unbiased manner using high-throughput multiplexed mass spectrometry. Proteomic analyses were performed in 5 µl serum samples with 11-plexed tandem mass tag (TMT) technology using an Orbitrap Lumos mass spectrometer. A SEQUEST-based database search engine was employed for peptide identification. Quantification was based on TMT reporter ion intensities. All patients were sampled during their participation in the GiACTA trial,1in which they received TCZ plus 26 weeks of prednisone (TCZ group) or placebo plus 26 or 52 weeks of prednisone (PRED group). Active disease was defined as the presence of cranial or PMR symptoms requiring treatment intensification regardless of ESR and CRP levels. Samples were selected if patients were in clear states of active or inactive disease at GiACTA systematic sample collection timepoints (baseline and weeks 4, 12, 24, 48). An exhaustive leave-2-out strategy was used to identify classification markers. All possible pairs of samples were isolated as test samples and the remaining training samples were used to identify the protein markers. Proteins with an absolute log2 fold concentration difference ≥0.5 between active and inactive samples and a P-value <0.1 were retained and sorted based on the metric -log10(P-value)*absolute(log2 fold change). Top markers within each training set were selected to generate normalized ranks {0,1} across all samples. A mean rank was calculated for every sample. The set of normalized ranks for the test samples across all sets of top markers were bootstrapped for each test sample 100 times with replacement. The bootstrapped rankings were evaluated by determining areas under the curves (AUC) of receiver operator characteristic (ROC) curves.Results:The PRED group included 21 patients (active, n = 16; inactive, n = 5) and the TCZ group included 21 patients (active, n = 14; inactive, n = 7). Using high-throughput sample preparation methods without applying any depletion of known highly abundant serum proteins, we quantified 760 proteins across all samples and 344 proteins in at least half the samples. Compared to inactive PRED-treated patients, active PRED-treated patients showed significant overexpression of several acute phase reactants including serum amyloid A1 and 2 (SAA1, SAA2) and complement factor H (CFH) (Fig. 1a). The magnitude of concentration change and the level of statistical significance observed for SSA1, SSA2 and CFH in PRED-treated patients were higher than those of CRP (Fig. 1a). Compared to inactive TCZ-treated patients, active TCZ-treated patients demonstrated significant overexpression of multiple biomarkers including haptoglobin, haptoglobin precursor, SSA2 and complement factor 4A, and underexpression of peptidase inhibitor 16 (Fig. 1b), a protein involved in vascular and regulatory T cell biology. Sets of 10 biomarkers resulted in a classification of active versus inactive disease with ROC AUCs of 0.89 (95% CI 0.79-0.96) in the PRED group (Fig. 2a) and 0.97 (95% CI 0.95-0.97) in the TCZ group (Fig. 2b).Conclusion:We identified several differentially expressed serum proteins in GCA patients with active and inactive disease receiving prednisone monotherapy or TCZ-based treatment regimens. In both treatment groups, a signature of biomarkers classified disease activity status with high accuracy. Haptoglobin, a readily available laboratory test, may be useful in monitoring disease activity in GCA patients receiving IL-6 blockade therapy.References:[1]Stoneet al.NEJM2017Disclosure of Interests:Sebastian Unizony Grant/research support from: Genentech, Inc., Robert Morris: None declared, Johannes Kreuzer: None declared, Wilhelm Haas: None declared, John H.

Abstract
Background:In part 1 of the 52-week, double-blind GiACTA trial, patients with giant cell arteritis (GCA) who received weekly tocilizumab (TCZ) plus prednisone tapering reported improvement in the 36-item Short-Form Health Survey (SF-36) Mental Component Summary (MCS) and Physical Component Summary scores and FACIT-Fatigue scores that were statistically significant and clinically meaningful compared with patients who received prednisone alone.1Objectives:To analyze whether benefit in SF-36 MCS was maintained in patients originally assigned to TCZ compared with those originally assigned to placebo (PBO) plus a 26- or 52-week prednisone taper among patients who achieved clinical remission at week 52 and maintained treatment-free clinical remission in the 2-year, long-term extension of GiACTA.Methods:At the end of part 1, patients entered open-label part 2, in which GCA therapy (including initiation/termination of open-label TCZ and/or GCs) was given at the investigator’s discretion according to disease status. Change from baseline in SF-36 MCS score was compared for combined original TCZ (n = 33) and PBO (n = 17) patients who achieved clinical remission at week 52 and maintained treatment-free (no TCZ or GCs) clinical remission in part 2 using a repeated-measures model. The minimal clinically important difference (MCID) for SF-36 MCS is >2.5.2Results:During treatment, SF-36 MCS scores in all 50 patients who maintained treatment-free clinical remission in part 2 had diverged between the TCZ and PBO groups as early as 36 weeks after baseline, with greater improvements evident in the TCZ group (Figure). The difference in least square means (LSM) change between TCZ and PBO was statistically significant at week 52 (p= 0.016) and maintained at weeks 100 (p= 0.023) and 156 (p= 0.002). The LSM difference (95% CI) between TCZ and PBO at weeks 52, 100, and 156 was 5.6 (1.1-10.2), 6.5 (0.9-12.1), and 7.4 (2.9-11.9), respectively, exceeding the MCID.Conclusion:Among patients who maintained treatment-free clinical remission during part 2 of GiACTA, those originally assigned to receive TCZ plus a prednisone taper during part 1 maintained statistically significant and clinically meaningful improvements in SF-36 MCS up to week 156 compared with those originally assigned to receive PBO plus a prednisone taper in part 1. This was true even though neither of the patient groups received TCZ or GC treatment after they achieved clinical remission at week 52.References:[1]Strand V et al.Arthritis Res Ther2019;21:64.[2]Lubeck DP.Pharmacoeconomics2004;22:27-38.Disclosure of Interests:John H.

Abstract
Background:In part 1 of the 52-week, double-blind GiACTA trial, tocilizumab (TCZ) every week (QW) or every other week (Q2W) + prednisone tapering reduced the risk for flare versus placebo (PBO) + 26-week prednisone tapering among patients with new-onset giant cell arteritis (GCA) at baseline. Among patients with relapsing GCA, TCZ QW but not Q2W + prednisone reduced the risk for flare versus both PBO groups, and there was separation in the time to flare between the TCZ QW and Q2W groups.1Objectives:To report time to first flare and potential cumulative glucocorticoid (GC) sparing over 3 years of the GiACTA trial (part 1 + 2-year open-label part 2) among patients with new-onset or relapsing GCA.Methods:At the end of part 1, patients entered open-label part 2, in which GCA therapy (including initiation/termination of open-label TCZ and/or GCs) was given at the investigator’s discretion according to disease status. Time to first GCA flare during the 3-year study period was assessed using Kaplan-Meier analysis for patients in the intention-to-treat population according to disease onset status at baseline (new-onset/relapsing) based on their originally assigned treatment groups: TCZ QW, TCZ Q2W, or pooled PBO (PBO+26-week and PBO+52-week prednisone taper).Results:Among patients randomly assigned in part 1, 47 of 100 (47%) in the TCZ QW group, 26 of 49 (53%) in the TCZ Q2W group, and 46 of 101 (46%) in the pooled PBO group had new-onset GCA at baseline; the rest had relapsing GCA. Median time to first flare over 3 years was longer for patients assigned to TCZ treatment in part 1 than for patients assigned to PBO; Kaplan-Meier analysis showed a clear separation between the TCZ QW and the pooled PBO groups over 3 years for patients with new-onset and relapsing GCA (Figure 1A). Separation between the TCZ QW and TCZ Q2W groups was also observed over 3 years in patients with new-onset and relapsing GCA, although this was more evident in patients with relapsing GCA (Figure 1B). Higher proportions of patients in the TCZ QW group (new-onset, 49%; relapsing, 47%) than the pooled PBO group (new-onset, 28%; relapsing, 31%) and the TCZ Q2W group (new-onset, 27%; relapsing, 35%) remained flare-free during their entire treatment period. Cumulative prednisone dose over 3 years was lower for patients originally assigned to TCZ QW versus those originally assigned to PBO for patients with new-onset GCA and those with relapsing GCA at baseline (Figure 2).Conclusion:In this 3-year analysis of GiACTA parts 1 and 2, time to first flare favored TCZ QW over TCZ Q2W in patients with new-onset and relapsing GCA. TCZ QW delayed time to first flare and resulted in lower cumulative GC exposure compared with PBO in patients with new-onset and relapsing GCA, supporting TCZ QW dosing in patients with GCA regardless of disease onset.References:[1]Stone JH et al.

Abstract
Background:The efficacy and safety of intravenous (IV) and subcutaneous (SC) tocilizumab (TCZ) in combination with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and as monotherapy in patients with rheumatoid arthritis (RA) has been demonstrated in large clinical trials and real-world data studies. The Health Assessment Questionnaire Disability Index (HAQ-DI) is commonly used to assess physical function in patients with RA. While HAQ-DI outcomes at Week 24 in TCZ clinical trials have been reported, outcomes at Week 12 and results stratified by treatment response categories at Weeks 12 and 24 have not been previously described.Objectives:To report the association between change in HAQ-DI from baseline to Weeks 12 and 24 and Disease Activity Score in 28 joints (DAS28) response categories in patients who received TCZ or comparators in TCZ clinical trials.Methods:Data from patients with active RA who received TCZ or a comparator from 6 Phase III or IV TCZ-IV studies (OPTION [NCT00106548], RADIATE [NCT00106522], TOWARD [NCT00106574] LITHE [NCT00109408], ACT-RAY [NCT00810199] and ADACTA [NCT01119859]) and 1 Phase III TCZ-SC study (BREVACTA [NCT01232569]) were analyzed. Mean change in HAQ-DI score at Weeks 12 and 24 was assessed in patients stratified by DAS28 disease activity level (DAS28 < 2.6 [remission], DAS28 ≥ 2.6 to ≤ 3.2 [low disease activity; LDA], DAS28 > 3.2 to ≤ 5.1 [moderate disease activity; MDA], DAS28 > 5.1 [high disease activity; HDA] at Weeks 12 and 24. The adjusted least squares mean (LSM) change from baseline was estimated using a mixed model with repeated measures, including region (North America vs non-North America), RA duration (> 2 years vs ≤ 2 years), baseline HAQ-DI and DAS28, treatment, visit, visit by treatment and visit by baseline HAQ-DI.Results:Data from 5051 patients were included. Across all studies, the mean duration of RA ranged from 6.3 to 12.6 years. At baseline, patients had severe RA with a mean DAS28 ≥ 6.3; baseline HAQ-DI was ≥ 1.5. At Week 12, patients who achieved remission or LDA had greater improvements in HAQ-DI than those in MDA or HDA (Figure 1). Results were similar at Week 24 (Figure 2). Among patients who received TCZ and achieved remission or LDA, mean improvement in HAQ-DI was ≥ 0.65 and ≥ 0.44, respectively, at Week 12 (Figure 1) and ≥ 0.48 and ≥ 0.43 at Week 24 (Figure 2). Mean changes in HAQ-DI were similar between patients who received TCZ-IV in combination with MTX or as monotherapy (ACT-RAY) and in those who received TCZ-IV or ADA as monotherapy (ADACTA).Conclusion:Patients with long-standing, severe RA who received IV or SC TCZ as monotherapy or in combination with csDMARDs had improvement in physical function and disease activity at Week 12 that was maintained at Week 24. Overall, across all the trials, response to treatment was associated with improvement in physical function.Acknowledgments :This study was sponsored by Genentech, Inc.

Abstract
INTRODUCTION Oral glucocorticoids (GC) have been the mainstay of treatment for giant cell arteritis (GCA). We estimated the risk and dose-effect relationship of potential GC-related adverse events (AEs) in patients with GCA. METHODS This retrospective, observational cohort study utilized data from the IBM Explorys Electronic Health Records database from 2008 through 2016. Inclusion criteria included the presence of at least two GCA diagnostic codes in subjects aged 50 or older along with supporting laboratory [C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR)], prescription data on oral GCs, and at least 12 months of follow-up before and after the first oral GC prescription for GCA (index date). Potential AEs captured on the basis of new diagnoses, prescriptions, and laboratory tests were assessed during the 12 months post-index date. Results were descriptively summarized across cohorts according to quartiles (Q) of mean daily GC dose measured over the first 6 months of follow-up (Q1, ≥ 1.00 to ≤ 13.75 mg; Q2, > 13.75 to ≤ 25.00 mg; Q3, > 25.00 to ≤ 40.00 mg; Q4, > 40.00 mg). RESULTS We identified 785 eligible patients with GCA. The mean (SD) age of the cohort was 76 (9) years and 70% were female. The mean oral GC dose during the first 6 months post-index was 28.9 mg/day. A dose-effect response was observed from Q1 to Q4 in the following potential GC-related AEs: newly diagnosed type 2 diabetes/HbA1c > 7.5% (range 7.5-24.5%), blood glucose ≥ 200 mg/dL (range 7.5-15%), serious infection (range 16.8-24.8%), cataracts (range 12.0-21.7%), gastrointestinal bleed/ulcer (range 6.0-11.8%), and increase in BMI ≥ 5 units (range 4.1-6.4). CONCLUSIONS In patients with GCA, potential GC-related AEs increased with higher daily oral GC doses. This highlights the need for effective therapies that reduce GC exposure and toxicity.

Abstract
OBJECTIVE To examine the relationship of antineutrophil cytoplasmic antibody (ANCA) type and ANCA-associated vasculitis (AAV) diagnosis with demographic features, disease manifestations, and clinical outcomes. We focused on patients who account for the differences between ANCA type and disease type classifications: anti-myeloperoxidase (MPO)-ANCA-positive and ANCA-negative patients with granulomatosis with polyangiitis (Wegener's) (GPA). METHODS We performed a pooled analysis of the Wegener's Granulomatosis Etanercept Trial and the Rituximab in ANCA-Associated Vasculitis trial comparing patients with MPO-ANCA-positive GPA and patients with ANCA-negative GPA to patients with proteinase 3 (PR3)-ANCA-positive GPA and patients with MPO-ANCA-positive microscopic polyangiitis (MPA). RESULTS Of the 365 patients analyzed, 273 (75%) had PR3-ANCA-positive GPA, 33 (9%) had MPO-ANCA-positive GPA, 15 (4%) had ANCA-negative GPA, and 44 (12%) had MPO-ANCA-positive MPA. MPO-ANCA-positive GPA patients were younger at diagnosis compared to MPO-ANCA-positive MPA patients (53 versus 61 years; P = 0.02). Their disease manifestations and rates of relapse were similar to those of PR3-ANCA-positive GPA patients. Relapse was more frequent in MPO-ANCA-positive GPA patients than in patients with MPO-ANCA-positive MPA at trial entry as well as at 12 and 18 months. ANCA-negative patients with GPA had lower Birmingham Vasculitis Activity Score for Wegener's Granulomatosis scores at trial entry than PR3-ANCA-positive patients with GPA (4.5 versus 7.7; P < 0.01), primarily because of a lower prevalence of renal involvement. CONCLUSION We were unable to demonstrate important clinical differences between MPO-ANCA-positive and PR3-ANCA-positive patients with GPA. The risk of relapse was associated more closely with disease type than with ANCA type in this patient cohort. These findings deserve consideration in the assessment of relapse risk in patients with AAV.

Abstract
OBJECTIVE Granulomatosis with polyangiitis (Wegener's) (GPA) is a type of antineutrophil cytoplasmic antibody-associated vasculitis that often entails severe end-organ damage and treatment-related complications that frequently lead to hospitalization and death. Nationwide trends in hospitalizations and in-hospital mortality over the past 2 decades are unknown and were evaluated in this study. METHODS Using the National Inpatient Sample, the largest all-payer inpatient database in the US, trends in hospitalizations with a discharge diagnosis of GPA (formerly Wegener's granulomatosis; International Classification of Disease, Ninth Revision, Clinical Modification code 446.4) between 1993 and 2011 were studied. Analyses were performed using hospital-level sampling weights to obtain US national estimates. RESULTS From 1993 to 2011, the annual hospitalization rate for patients with a principal diagnosis of GPA increased by 24%, from 5.1 to 6.3 per 1 million US persons (P < 0.0001 for trend); however, in-hospital deaths in this group declined by 73%, from 9.1% to 2.5% (P < 0.0001 for trend), resulting in a 66% net reduction in the annual in-hospital mortality rate. The median length of stay declined by 20%, from 6.9 days in 1993 to 5.5 days in 2011 (P = 0.0002 for trend). Infection was the most common principal discharge diagnosis when GPA was a secondary diagnosis, including among those who died during hospitalization. CONCLUSION The findings from these nationally representative, contemporary inpatient data indicate that the in-hospital mortality of GPA has declined substantially over the past 2 decades, while the overall hospitalization rate for GPA increased slightly. Infection remains a common principal hospitalization diagnosis among GPA patients, including hospitalizations resulting in mortality.

Abstract
OBJECTIVES Randomised-controlled trials have recently proven the efficacy of the interleukin (IL)-6 receptor antagonist tocilizumab (TCZ) in giant cell arteritis (GCA). However, the mechanism of action of IL-6 blockade in this disease is unknown. Moreover, the role of regulatory T (Treg) cells in the pathogenesis of GCA remains underexplored. Given the plasticity of Tregs and the importance of IL-6 in their biology, we hypothesised that TCZ might modulate the Treg response in GCA. We therefore characterised the Treg compartment of patients with GCA treated with TCZ. METHODS We classified 41 patients with GCA into three groups: active disease (aGCA, n=11), disease remission on corticosteroids (rGCA-CS, n=19) and disease remission on TCZ (rGCA-TCZ, n=11). Healthy controls (HCs) were included for comparison. We determined the frequency, phenotype and function of peripheral blood Tregs. RESULTS Patients with aGCA demonstrated a hypoproliferating Treg compartment enriched in IL-17-secreting Tregs (IL-17+Tregs). Tregs in patients with aGCA disproportionally expressed a hypofunctional isoform of Foxp3 that lacks exon 2 (Foxp3Δ2). Foxp3Δ2-expressing Tregs coexpressed CD161, a marker commonly associated with the Th17 linage, significantly more often than full-length Foxp3-expressing Tregs. Compared with those of HCs, GCA-derived Tregs demonstrated impaired suppressor capacity. Treatment with TCZ, in contrast to CS therapy, corrected the Treg abnormalities observed in aGCA. In addition, TCZ treatment increased the numbers of activated Tregs (CD45RA-Foxp3high) and the Treg expression of markers of trafficking (CCR4) and terminal differentiation (CTLA-4). CONCLUSIONS TCZ may exert its therapeutic effects in GCA by increasing the proliferation and activation of Tregs, and by reverting the pathogenic Treg phenotype seen during active disease.

Abstract
OBJECTIVE To evaluate whether the classification of patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) according to ANCA type (anti-proteinase 3 (PR3) or anti-myeloperoxidase (MPO) antibodies) predicts treatment response. METHODS Treatment responses were assessed among patients enrolled in the Rituximab in ANCA-associated Vasculitis trial according to both AAV diagnosis (granulomatosis with polyangiitis (GPA)/microscopic polyangiitis (MPA)) and ANCA type (PR3-AAV/MPO-AAV). Complete remission (CR) was defined as disease activity score of 0 and successful completion of the prednisone taper. RESULTS PR3-AAV patients treated with rituximab (RTX) achieved CR at 6 months more frequently than did those randomised to cyclophosphamide (CYC)/azathioprine (AZA) (65% vs 48%; p=0.04). The OR for CR at 6 months among PR3-AAV patients treated with RTX as opposed to CYC/AZA was 2.11 (95% CI 1.04 to 4.30) in analyses adjusted for age, sex and new-onset versus relapsing disease at baseline. PR3-AAV patients with relapsing disease achieved CR more often following RTX treatment at 6 months (OR 3.57; 95% CI 1.43 to 8.93), 12 months (OR 4.32; 95% CI 1.53 to 12.15) and 18 months (OR 3.06; 95% CI 1.05 to 8.97). No association between treatment and CR was observed in the MPO-AAV patient subset or in groups divided according to AAV diagnosis. CONCLUSIONS Patients with PR3-AAV respond better to RTX than to CYC/AZA. An ANCA type-based classification may guide immunosuppression in AAV. TRIAL REGISTRATION NUMBER NCT00104299; post-results.

Abstract
BACKGROUND Granulomatosis with polyangiitis (GPA) is associated with an increased risk of mortality; however, recent mortality trends in GPA are unknown. We evaluated this issue in a general population context. METHODS Using data collected between 1992 and 2013 by The Health Improvement Network in the United Kingdom, we identified individuals diagnosed as incident cases of GPA and up to 10 non-GPA controls matched on sex, age, year of birth, and year of GPA diagnosis. The cohort was divided into two based on the year of diagnosis (i.e., 1992-2002 and 2003-2013) to evaluate changes in mortality. We calculated hazard ratios for death using a Cox-proportional hazards model and the rate differences using an additive hazard model, while adjusting for potential confounders. RESULTS We identified 465 cases of GPA (mean age: 60 years, 52% male). The early cohort (1992-2002) GPA patients had considerably higher mortality rates than the late cohort (2003-2013) (i.e., 72.0 vs. 35.7 cases per 1000 person-years), as compared with a moderate improvement in the comparison cohorts between the two periods (19.8 vs. 17.0 cases per 1000 person-years). The corresponding absolute mortality rate difference was 52.2 (95% CI: 25.1-79.2) cases and 18.7 (95% CI: 8.3-29.1) cases per 1000 person-years (p for interaction = 0.025). The resulting HRs for mortality were 4.34 (95% CI: 2.72-6.92) and 2.41 (95% CI: 1.74-3.34), respectively (p for interaction = 0.043). CONCLUSION This population-based study suggests that survival of GPA patients has improved considerably over the past 2 decades, affirming the benefits of recent trends in the management of GPA and its complications.

Abstract
OBJECTIVE CD5+ B cells have been conceptualized as a possible surrogate for Breg cells. The aim of the present study was to determine the utility of CD5+ B cells as biomarkers in antineutrophil cytoplasmic antibody-associated vasculitis (AAV). METHODS The absolute and relative numbers (percentages) of CD5+ B cells (explanatory variables) were measured longitudinally during 18 months in 197 patients randomized to receive either rituximab (RTX) or cyclophosphamide (CYC) followed by azathioprine (AZA) for the treatment of AAV (Rituximab in ANCA-Associated Vasculitis [RAVE] trial). Outcome variables included disease activity (status of active disease versus complete remission), responsiveness to induction therapy, disease relapse, disease severity, and, in RTX-treated patients, relapse-free survival according to the percentage of CD5+ B cells detected upon B cell repopulation. RESULTS CD5+ B cell numbers were comparable between the treatment groups at baseline. After an initial decline, absolute CD5+ B cell numbers progressively increased in patients in the RTX treatment arm, but remained low in CYC/AZA-treated patients. In both groups, the percentage of CD5+ B cells increased during remission induction and slowly declined thereafter. During relapse, the percentage of CD5+ B cells correlated inversely with disease activity in RTX-treated patients, but not in patients who received CYC/AZA. No significant association was observed between the numbers of CD5+ B cells and induction treatment failure or disease severity. The dynamics of the CD5+ B cell compartment did not anticipate disease relapse. Following B cell repopulation, the percentage of CD5+ B cells was not predictive of time to flare in RTX-treated patients. CONCLUSION The percentage of peripheral CD5+ B cells might reflect disease activity in RTX-treated patients. However, sole staining for CD5 as a putative surrogate marker for Breg cells did not identify a subpopulation of B cells with clear potential for meaningful clinical use. Adequate phenotyping of Breg cells is required to further explore the value of these cells as biomarkers in AAV.

Abstract
OBJECTIVE The morbidity and mortality of hospitalized GCA patients have been unexplored. The aim of this study was to analyse inpatient complications experienced by patients with GCA. METHODS We used the Nationwide Inpatient Sample database to study a large group of patients admitted for pneumonia, myocardial infarction (MI), ischaemic stroke and femoral neck fracture. Patients were divided into two groups based on whether or not they had a diagnosis of GCA upon admission. Outcomes evaluated included inpatient mortality and the occurrence of adrenal insufficiency, deep vein thrombosis, pulmonary embolism and delirium. RESULTS From 2008 to 2011, 8 203 447 patients ≥50 years of age were discharged from US hospitals after admission with pneumonia, MI, stroke and femoral neck fracture. Among these patients, 9311 (0.11%) had GCA. Admissions for pneumonia, stroke and hip fracture were more frequent in GCA patients compared with those without GCA, accounting for 41.5% vs 39.4%, 24.9% vs 19.8% and 15.4% vs 14.2% of hospitalizations, respectively (P ≤ 0.001). Admissions for MI were more common in non-GCA patients (26.6% vs 18.2%, P < 0.001). During hospitalization, 4.1% of the GCA patients died, compared with 4.8% of those without GCA [odds ratio (OR) 0.73, P < 0.001). The GCA population suffered significantly more often from deep vein thrombosis (OR 2.08, P < 0.001), pulmonary embolism (OR 1.58, P < 0.001), delirium (OR 1.60, P < 0.001) and adrenal insufficiency (OR 4.95, P < 0.001). CONCLUSION Hospitalized GCA patients have lower mortality compared with the general inpatient population but greater risk of venous thromboembolism, delirium and adrenal insufficiency.

Abstract
INTRODUCTION Prior studies have demonstrated an increased frequency of antibodies to Porphyromonas gingivalis (Pg), a leading agent of periodontal disease, in rheumatoid arthritis (RA) patients. However, these patients generally had long-standing disease, and clinical associations with these antibodies were inconsistent. Our goal was to examine Pg antibody responses and their clinical associations in patients with early RA prior to and after disease-modifying antirheumatic drug (DMARD) therapy. METHODS Serum samples from 50 DMARD-naïve RA patients were tested using an enzyme-linked immunosorbent assay with whole-Pg sonicate. For comparison, serum samples were tested from patients with late RA, patients with other connective tissue diseases (CTDs), age-similar healthy hospital personnel and blood bank donors. Pg antibody responses in early RA patients were correlated with standard RA biomarkers, measures of disease activity and function. RESULTS At the time of enrollment, 17 (34%) of the 50 patients with early RA had positive immunoglobulin G (IgG) antibody responses to Pg, as did 13 (30%) of the 43 patients with late RA. RA patients had significantly higher Pg antibody responses than healthy hospital personnel and blood bank donors (P < 0.0001). Additionally, RA patients tended to have higher Pg antibody reactivity than patients with other CTDs (P = 0.1), and CTD patients tended to have higher Pg responses than healthy participants (P = 0.07). Compared with Pg antibody-negative patients, early RA patients with positive Pg responses more often had anti-cyclic citrullinated peptide (anti-CCP) antibody reactivity, their anti-CCP levels were significantly higher (P = 0.03) and the levels of anti-Pg antibodies correlated directly with anti-CCP levels (P < 0.01). Furthermore, at the time of study entry, the Pg-positive antibody group had greater rheumatoid factor values (P = 0.04) and higher inflammatory markers (erythrocyte sedimentation rate, or ESR) (P = 0.05), and they tended to have higher disease activity scores (Disease Activity Score based on 28-joint count (DAS28)-ESR and Clinical Disease Activity Index) and more functional impairment (Health Assessment Questionnaire). In Pg-positive patients, greater disease activity was still apparent after 12 months of DMARD therapy. CONCLUSIONS A subset of early RA patients had positive Pg antibody responses. The responses correlated with anti-CCP antibody reactivity and to a lesser degree with ESR values. There was a trend toward greater disease activity in Pg-positive patients, and this trend remained after 12 months of DMARD therapy. These findings are consistent with a role for Pg in disease pathogenesis in a subset of RA patients.

Abstract
OBJECTIVE The interleukin-6 pathway is up-regulated in giant cell arteritis (GCA), Takayasu arteritis (TA), and polymyalgia rheumatica (PMR). We retrospectively assessed the outcomes of 10 patients with relapsing/refractory GCA, TA, or PMR treated with tocilizumab (TCZ). METHODS Patients with GCA (n = 7), TA (n = 2), and PMR (n = 1) received TCZ. Seven subjects had failed at least 1 second-line agent. The outcomes evaluated were symptoms of disease activity, inflammatory markers, ability to taper glucocorticoids, and cross-sectional imaging when indicated clinically. RESULTS The mean followup time of this cohort since diagnosis was 27 months (range 16-60 months). The patients were treated with TCZ for a mean period of 7.8 months (range 4-12 months). Before TCZ therapy, the patients experienced an average of 2.4 flares/year. All patients entered and maintained clinical remission during TCZ therapy. The mean daily prednisone dosages before and after TCZ initiation were 20.8 mg/day (range 7-34.3 mg/day) and 4.1 mg/day (range 0-10.7 mg/day), respectively (P = 0.0001). The mean erythrocyte sedimentation rate declined from 41.5 mm/hour (range 11-68 mm/hour) to 7 mm/hour (range 2.2-11.3 mm/hour; P = 0.0001). The adverse effects of TCZ included mild neutropenia (n = 4) and transaminitis (n = 4). One patient flared 2 months after TCZ discontinuation. An autopsy on 1 patient who died from a postoperative myocardial infarction following elective surgery revealed persistent vasculitis of large and medium-sized arteries. CONCLUSION TCZ therapy led to clinical and serologic improvement in patients with refractory/relapsing GCA, TA, or PMR. The demonstration of persistent large-vessel vasculitis at autopsy of 1 patient who had shown a substantial response requires close scrutiny in larger studies.

Abstract
Patients with IgG4-related disease (IgG4-RD) typically have elevated serum concentrations of IgG4 and share histopathologic features that are similar across affected organ(s). IgG4-RD patients frequently require prolonged treatment with glucocorticoids and are often unable to taper these medications. Traditional disease-modifying antirheumatic drugs (DMARDs) are generally ineffective. We assessed the clinical and serologic responses to B lymphocyte depletion therapy in 10 consecutive patients with steroid- and DMARD-refractory IgG4-RD.Ten patients with IgG4-RD were treated with rituximab (RTX) (2 infusions of 1000 mg, 15 days apart). Clinical improvement was assessed by monitoring the patient's ability to taper prednisone to discontinuation and to stop DMARDs; by serial measurements of total IgG and IgG subclasses; and by follow-up radiologic assessments guided by the patient's particular pattern of organ involvement. We also developed and retrospectively applied the IgG4-RD Disease Activity Index and Flare Tool.Organ involvement included the pancreas, biliary tree, aorta, salivary glands (submandibular and parotid), lacrimal glands, lymph nodes, thyroid gland, and retroperitoneum. Nine of 10 patients demonstrated striking clinical improvement within 1 month of starting RTX. One patient with advanced thyroid fibrosis associated with Riedel thyroiditis and a history of disease in multiple other organ systems did not have improvement in the thyroid gland, but the disease did not progress to involve new organs. All 10 patients were able to discontinue prednisone and DMARDs following RTX therapy. Significant decreases in IgG concentrations were observed for the IgG4 subclass only. Four patients were re-treated with RTX after 6 months because of either symptom recurrence and increasing IgG4 concentration at the time of peripheral B cell reconstitution (n = 2) or because of physician discretion (n = 2). Repeated courses of RTX maintained their effectiveness and resulted in further decreases in IgG4 concentrations. In patients who had an increased IgG4 concentration at the time of presentation, the level of serum IgG4 appeared to be a reliable measure of disease activity.IgG4-RD is an idiopathic, multiorgan inflammatory disease in which diverse organ manifestations are linked by characteristic histopathologic and immunohistochemical features. Treatment with RTX led to prompt clinical and serologic improvement in refractory IgG4-RD in all patients with active inflammation. Serial treatments with RTX may lead to progressive declines in serum IgG4 concentrations and better disease control. Serum IgG4 concentrations may remain low, and clinical disease activity may remain quiescent even after B cell reconstitution in a significant proportion of patients.

Abstract
Pulmonary manifestations of systemic lupus erythematosus (SLE) typically include pleuritis, alveolar hemorrhage, and infectious pneumonia due to immunosuppression with less common entities including bronchiolitis, interstitial pneumonia, and pulmonary fibrosis. More rare manifestations include organizing pneumonia (OP) and diffuse alveolar damage (DAD). A similar but distinct entity of acute fibrinous and organizing pneumonia (AFOP), characterized by intra-alveolar fibrin deposition and associated organizing pneumonia, has been reported in association with connective tissue disorders, but has not been described in association with SLE. Reported herein is a patient with SLE and accompanying antiphospholipid syndrome with recent pulmonary embolism, persistent respiratory symptomology, and persistent radiographic abnormalities who underwent lung biopsy displaying features of AFOP. This case in conjunction with previous literature indicates that AFOP can be a manifestation of connective tissue disease including SLE and may be an underreported variant of medical lung disease due to overlap in histological characteristics with OP and DAD.
