Systemic Lupus Erythematosus Disease Activity Score Remission and Low Disease Activity States Discriminate Drug From Placebo and Better Health-Related Quality of Life.

Our objective was to evaluate the ability of Systemic Lupus Erythematosus Disease Activity Score (SLE-DAS) remission and low disease activity (LDA) to discriminate active drug from placebo and to discriminate outcomes in the patients' perspective (health-related quality of life [HR-QoL]) in SLE trials. This was a post hoc analysis of the pooled Belimumab in Subjects With SLE (BLISS)-52 (NCT00424476) and BLISS-76 (NCT00410384) trials data. SLE-DAS remission and LDA attainment and discrimination between belimumab and placebo at 52 weeks were compared using chi-square tests. At week 52, 36-item Short Form Health Survey (SF-36) and Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F) scores were compared between patients attaining SLE-DAS remission versus nonremission and SLE-DAS LDA versus non-LDA using the t-test and Mann-Whitney test. Mean changes from week 0 to 52 in SF-36 and FACIT-F scores were compared between groups using multivariate regression analysis adjusted for baseline scores. At week 52, significantly more patients attained SLE-DAS LDA taking belimumab 1 mg/kg (17.9% vs 13.0%; P = 0.023; odds ratio [OR] 1.459; relative risk [RR] 1.377; number needed to treat [NNT] 20.4) and 10 mg/kg (21.7% vs 13.0%; P < 0.001; OR 1.853; RR 1.668; NNT 11.5) compared with placebo. Likewise, more patients attained SLE-DAS remission taking belimumab 10 mg/kg compared to placebo (14.7% vs 10.1%; P = 0.019; OR 1.532; RR 1.454; NNT 21.7). At week 52, patients attaining SLE-DAS remission and LDA presented higher SF-36 domain and summary scores (all P < 0.001) and FACIT-F scores (both P < 0.001). Mean improvements from baseline in SF-36 and FACIT-F scores were significantly higher in patients achieving SLE-DAS remission and LDA. SLE-DAS remission and LDA showed discriminant ability for identifying patients receiving active drug in SLE clinical trials. Attainment of these SLE-DAS targets are associated with better HR-QoL.

Anti-Peptidylarginine Deiminase 4 Autoantibodies and Disease Duration as Predictors of Treatment Response in Rheumatoid Arthritis.

Given that autoantibodies to peptidylarginine deiminase 4 (PAD4) are associated with erosive disease in established rheumatoid arthritis (RA), this study was conducted to compare the clinical and prognostic use of anti-PAD4 antibodies in patients with early and established RA. Sera from patients with early (duration <2 years; n=422) or established (duration ≥2 years; n=359) RA from two randomized clinical trials of tofacitinib ± methotrexate compared with adalimumab + MTX or MTX alone were evaluated for the presence of anti-PAD4 and anti-PAD3/4 antibodies at baseline and posttreatment time points. Summary statistics were calculated for demographic, clinical, and serological characteristics, and generalized estimating equations were used to model clinical outcomes by disease duration according to anti-PAD4 status. Anti-PAD4 antibodies were present in 22% and 40% of patients with early and established RA, respectively, stable following treatment, and associated with baseline joint damage only in established RA. In early RA, baseline anti-PAD4 antibodies were associated with a greater improvement in disease activity score 28-joint count using C-reactive protein levels after treatment compared with individuals with negative anti-PAD4 (P = 0.049). Tofacitinib ± MTX was more broadly efficacious than MTX alone at improving clinical outcomes in early and established RA, irrespective of anti-PAD4 status (P < 0.05 for all), whereas adalimumab + MTX exhibited differential benefits in achieving disease activity score remission in early RA (P = 0.036) and American College of Rheumatology 20 responses in established RA (P = 0.002). Differences in prevalence, clinical associations, and treatment-response outcomes according to anti-PAD4 antibody status in early and established RA suggests the existence of a therapeutic window to prevent the accumulation of irreversible joint damage in early patients with RA with anti-PAD4 antibodies.

Impact of interstitial lung disease on clinical remission and unfavourable events of rheumatoid arthritis: results from the IORRA cohort.

We aimed to examine the impact of concomitant interstitial lung disease (ILD) on achieving clinical remission and the occurrence of unfavourable clinical events in patients with RA. Among the participants in the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort from 2011 to 2012, patients not achieving remission of 28-joint disease activity score (DAS28) at baseline and those with chest CT images were enrolled. Based on the chest CT images, the patients were divided into two groups: the ILD group and non-ILD group. The associations among the presence of ILD with time to achieving DAS28 remission and development of death, hospitalized infection, major adverse cardiac events (MACE), or malignancy within 5 years were evaluated using time-dependent Cox regression models. We enrolled 287 patients in the ILD group and 1235 in the non-ILD group. DAS28 remission was achieved at least once in 55.7% and 75.0% of the ILD and non-ILD groups within 5 years, respectively. Presence of ILD was significantly associated with failure to achieve DAS28 remission (adjusted hazard ratio [aHR]: 0.71; 95% CI: 0.58, 0.89). ILD was also a significant factor associated with death (aHR: 3.24; 95% CI: 2.08, 5.03), hospitalized infection (aHR 2.60; 95% CI: 1.77, 3.83), MACE (aHR: 3.40; 95% CI: 1.76, 6.58), and lung cancer (aHR: 16.0; 95% CI: 3.22, 79.2), but not with malignant lymphoma (aHR: 2.27; 95% CI: 0.59, 8.81). Concomitant ILD was a significant factor associated with failure to achieve clinical remission and the occurrence of the unfavourable clinical events in patients with RA.

Benefits of Autoantibody Enrichment in Early RheumatoidArthritis: Analysis of Efficacy Outcomes in Four Pooled Abatacept Trials.

The efficacy of abatacept is enhanced in anti-citrullinated protein antibody (ACPA) and rheumatoid factor (RF)-positive versus -negative patients with rheumatoid arthritis (RA). Four early RA abatacept trials were analyzed to understand the differential impact of abatacept among patients with SeroPositive Early and Active RA (SPEAR) compared to non-SPEAR patients. Pooled patient-level data from AGREE, AMPLE, AVERT, and AVERT-2 were analyzed. Patients were classified as SPEAR if they were ACPA +, RF +, disease duration < 1year, and Disease Activity Score-28 (DAS28) C-reactive protein (CRP) ≥ 3.2 at baseline; non-SPEAR otherwise. Outcomes included: American College of Rheumatology (ACR) 20/50/70 at week 24; mean change from baseline to week 24 for DAS28 (CRP), Simple Disease Activity Index (SDAI), ACR core components; DAS28 (CRP) and SDAI remission. Adjusted regression analyses among abatacept-treated patients compared SPEAR and non-SPEAR patients, and in full trial population estimating how the efficacy of abatacept versus comparators [adalimumab + methotrexate, methotrexate] was modified by SPEAR status. The study included 1400 SPEAR and 673 non-SPEAR patients; most were female (79.35%), white (77.38%), and with a mean age 49.26 (SD 12.86) years old. Around half with non-SPEAR were RF + and three-quarters ACPA +. Stronger improvements from baseline to week 24 were observed in almost all outcomes for abatacept-treated SPEAR versus non-SPEAR patients or versus SPEAR patients treated with comparators. Larger improvements were observed for SPEAR patients among the abatacept-treated population, and more strongly improved efficacy among SPEAR patients for abatacept than comparators. This analysis, including large patient numbers of early-RA abatacept trials, confirmed beneficial treatment effects of abatacept in patients with SPEAR versus non-SPEAR.

P116 Systematic review of the prevalence of foot disease activity in patients classed in disease activity score-28 remission

Abstract Background/Aims The disease activity score-28 (DAS-28) is commonly used in rheumatoid arthritis (RA) to identify people in remission, low, moderate and high disease activity to guide medical management. The DAS-28 omits foot joints and recent research suggests that this may place people with foot disease at risk of poor outcomes. However, little is known concerning the prevalence of foot disease amongst people with RA who are considered to be in remission according to the DAS-28. The aim of this review was to estimate the prevalence of foot disease activity in patients classed in DAS-28 remission. Methods Databases included in the search were MEDLINE, CINAHL, AMED and HSNAE. Keywords including “Rheumatoid arthritis”, “disease activity score”, “remission”, “foot joint”, “ankle joint”, “clinical examination”, “ultrasound” and “synovitis” and synonyms using MeSH terms comprised the search strategy. Studies which reported the prevalence of foot disease activity in patients classed in DAS-28 remission were included in this review. Participants were diagnosed with RA, and reported foot disease prevalence from clinical examination (CE), or musculoskeletal ultrasound (MSUS) assessments. Methodological quality of studies were independently assessed by two researchers using the Joanna Briggs Institution prevalence critical appraisal tool (JBI PCAT). Results were subject to narrative synthesis and reported according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses statement. Results Of 44 studies screened for eligibility, 7 were included and a further 2 that met inclusion criteria identified from reference lists were included. A total of 933 participants (mean age range 44-63 years) took part across 9 included studies. Five studies used MSUS (B-mode synovial hypertrophy/power Doppler) while 4 used clinical examination (tenderness/swelling) to identify synovitis. Significant variation across included studies was apparent for foot and ankle sites assessed and method of scoring for the presence of foot disease. For presence of synovitis in one or more foot joints assessed, synovial hypertrophy prevalence detected using B-mode MSUS ranged from 23.4-88.6% (4 studies, n = 687). Synovitis affecting one or more metatarsophalangeal joint (MTPJ) detected using power Doppler was present in 7.5% (1 study, n = 125). Synovitis detected clinically affecting any foot joint was present in 35-43% (3 studies, n = 542). Joint tenderness was detected in 1 or more MTPJs in 6.3% (1 study, n = 187). Methodological quality was generally high, ranging from 7-9/9. Conclusion Methodological quality was high but heterogeneous approaches for foot synovitis assessment and scoring were adopted across included studies, making comparisons difficult. The results of this review suggest that foot synovitis is common in people who are classed as in DAS-28 remission. These patients may be at risk of ongoing foot problems and poor functional and radiographic outcomes. Disclosure K. McIlwaine: None. G.J.

Oral or Parenteral Methotrexate for the Treatment of Polyarticular Juvenile Idiopathic Arthritis.

Subcutaneous methotrexate injections are considered to be more effective or work faster than oral methotrexate. Therefore, the extent and the kinetics of response were analyzed in juvenile idiopathic arthritis patients treated with oral versus subcutaneous methotrexate. The BIKER databank was searched for biologics-naive juvenile idiopathic arthritis patients treated with methotrexate as initial treatment. The Juvenile Arthritis Disease Activity Score-10 defini- tion of remission and the pediatric American College of Rheumatology's response parameters were utilized as outcome criteria. A total of 410 polyarticular juvenile idiopathic arthritis patients receiving oral methotrexate were compared to 384 patients receiving subcutaneous methotrexate. Rheumatoid factor-negative polyarthritis was the most common juvenile idiopathic arthritis category (50%/51%) in this cohort followed by extended oligoarthritis (27%/26%), polyarticular psoriatic arthritis (18%/16%), and few had rheumatoid factor-positive polyarthritis (5%/8%). The oral cohort's disease duration (2.3 ± 3.0 vs. 1.9 ± 2.7) was significantly longer (P=.04), although their age at onset and baseline were similar. Furthermore, at baseline, disease activity (Juvenile Arthritis Disease Activity Score-10 16.5 ± 7.2 vs. 14.7 ± 8.2; P = .001 due to a higher active joint count 9.0 ± 10.1 vs. 7.4 ± 7.7; P = .011) was higher in the subcutaneous cohort. The weekly methotrexate doses were comparable with 13.6 ± 5.4 mg/m2 and 13.3 ± 4.5 mg/m2, respectively. With oral/subcutaneous methotrexate, a pediatric American College of Rheumatology's 90 was achieved in 98(38.3%)/128(40.4%), while 96(38.1 %)/75(40.1%) attained Juvenile Arthritis Disease Activity Score remission after 12 months of therapy. There was no difference in the early kinetics of response according to Kaplan-Meyer analysis. Adverse events including nausea, vomiting, and increased transaminases were considerably more common after methotrexate subcutaneous administration than after oral treatment. In terms of effectiveness, but not safety, our retrospective analysis found some advan- tages of subcutaneous methotrexate. Adverse effects limit treatment continuance and thus must be considered a disadvantage. Furthermore, oral methotrexate eliminates the need for injections, which is especially essential for younger children. Controlled, randomized prospective trials in children and juvenile patients are necessary for definitive recommendations for the subcutaneous route of admin- istration of methotrexate therapy.

Infliximab biosimilar-to-biosimilar switching in patients with inflammatory rheumatic disease: clinical outcomes in real-world patients from the DANBIO registry

ObjectiveSuccessful uptake of biosimilars in rheumatology is limited by lack of real-world evidence regarding effectiveness of biosimilar-to-biosimilar switching. We investigated infliximab biosimilars CT-P13-to-GP1111 switching among patients with rheumatoid arthritis (RA),...

Serum Reactive Oxygen Metabolites as a Predictor of Clinical Disease Activity Index, Simplified Disease Activity Index, and Boolean Remissions in Rheumatoid Arthritis Patients Treated With Biologic Agents.

IntroductionReactive oxygen metabolites (ROMs) are metabolite hydroperoxides in the blood, and their serum levels were associated with the disease activity score 28 (DAS28) in patients with rheumatoid arthritis (RA). In this study, we aimed to investigate whether ROMs would be predictive of the clinical disease activity index (CDAI) remission, simplified disease activity index (SDAI) remission, or Boolean remission.Materials and methodsFifty-one biologic agents (BA)-naïve RA patients were included in this observational study. Associations between ROMs, C-reactive protein, matrix metalloproteinase-3, DAS28-erythrocyte sedimentation rate (ESR), CDAI, SDAI, and health assessment questionnaire (HAQ) at 12 weeks and the DAS28, CDAI, SDAI, and Boolean remission rates at 52 weeks were investigated.ResultsThe DAS28, CDAI, SDAI, and Boolean remission rates at 52 weeks were 66.7, 52.9, 54.9, and 54.9%, respectively. A multivariate logistic regression analysis revealed that ROMs and HAQ at 12 weeks were associated with the CDAI, SDAI, and Boolean remission at 52 weeks. Receiver operating characteristic analyses demonstrated that the cut-off value for CDAI, SDAI, and Boolean remission was 389.5 U.Carr.ConclusionReactive oxygen metabolites at 12 weeks of initial treatment with BAs was a predictor for CDAI, SDAI, and Boolean remission at 52 weeks. Serum levels of ROMs may be a useful biomarker in the current treatment strategy aiming at early remission of RA.

The impact of fatigue on patients with psoriatic arthritis: amulti-center study of the TLAR-network.

Fatigue is a substantial problem in patients with psoriatic arthritis (PsA) that needs to be considered in the core set of domains. This study aimed to evaluate fatigue and its relationship with disease parameters, functional disability, anxiety, depression, quality of life, and correlation with disease activity as determined by various scales. A total of 1028 patients (677 females, 351 males) with PsA who met the CASPAR criteria were included [Turkish League Against Rheumatism (TLAR) Network multicenter study]. The demographic features and clinical conditions of the patients were recorded. Correlations between fatigue score and clinical parameters were evaluated using the Disease Activity Score 28 (DAS28), Disease Activity in Psoriatic Arthritis (DAPSA), Clinical DAPSA (cDAPSA), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Fibromyalgia Rapid Screening Tool (FiRST), minimal disease activity (MDA), and very low disease activity (VLDA). Fatigue was assessed with the Functional Assessment of Chronic Illness Therapy (FACIT-F) and a 10-point VAS (VAS-F). The mean age of the patients was 47 (SD: 12.2) years, and the mean disease duration was 6.4 (SD: 7.3) years. The mean VAS-F score was 5.1 (SD: 2.7), with fatigue being absent or mild, moderate, and severe in 12.8%, 24.6%, and 62.5% of the patients, respectively. Fatigue scores were significantly better in patients with DAS28 remission, DAPSA remission, cDAPSA remission, MDA, and VLDA (p < 0.001). Fatigue scores significantly increased with increasing disease activity levels on the DAS28, DAPSA, and cDAPSA (p < 0.001). VAS-F scores showed correlations with the scores of the BASDAI, BASFI, PsAQoL, HAD-A, FiRST, pain VAS, and PtGA. FiRST scores showed fibromyalgia in 255 (24.8%) patients. FACIT-F and VAS-F scores were significantly higher in patients with fibromyalgia (p < 0.001). In regression analysis, VLDA, BASDAI score, FiRST score, high education level, HAD-Anxiety, and BMI showed independent associations with fatigue. Our findings showed that fatigue was a common symptom in PsA and disease activity was the most substantial predictor, with fatigue being less in patients in remission, MDA, and VLDA. Other correlates of fatigue were female gender, educational level, anxiety, quality of life, function, pain, and fibromyalgia.

Circulating calprotectin (S100A8/A9) is higher in rheumatoid arthritis patients that relapse within 12\u2009months of tapering anti-rheumatic drugs

ObjectiveTo investigate whether calprotectin (S100A8/A9 or MRP8/14), an inflammatory complex released by monocytes, could indicate residual subclinical inflammation in rheumatoid arthritis (RA) patients who are in stable remission on disease-modifying anti-rheumatic drugs (DMARDs) and serve as a marker for disease flare after DMARD tapering.MethodsWe used data from two trials. Patients from the IMPROVED study had early (< 2 years) RA, and when they achieved disease activity score remission (DAS44 < 1.6), they stopped methotrexate to attempt drug-free remission. Patients from the RETRO study had established RA in stable remission (DAS28 < 2.6) and either tapered by 50% or stopped (biological or conventional) DMARDs. Circulating calprotectin at the tapering time point was determined by ELISA, and its predictive value for flare (loss of remission) within 12 months of DMARD tapering/stopping was determined.ResultsIn both IMPROVED (n = 104) and RETRO (n = 57), patients that flared within 12 months had higher calprotectin at the moment of DMARD tapering/stopping. Twofold higher calprotectin at the moment of DMARD tapering/stopping was associated with an increased risk (odds ratio) of flare of 1.07 (95% CI 0.98–1.18, p = 0.14) in the IMPROVED and 3.62 (95% CI 1.76–7.46, p < 0.001) in the RETRO. Correcting for clinical predictors of flare (DAS at study inclusion, anti-CCP2 positivity, gender) did not change these estimates. The area under the receiver operating curve of calprotectin levels for predicting flare within 12 months was 0.63 (95% CIs 0.51–0.76) in the IMPROVED study and 0.80 (95% CIs 0.69 to 0.92) in the RETRO study.ConclusionCirculating calprotectin levels in RA patients in remission on DMARDs are higher in patients that will flare upon DMARD tapering/stopping. Since the differences between the cohorts precluded definitive conclusions, more research is needed to determine whether calprotectin has prognostic value in predicting flare after attempting drug tapering in RA.Trial registrationIMPROVED, ISRCTN11916566.

Sustained remission with methotrexate monotherapy after 22-week induction treatment with TNF-alpha inhibitor and methotrexate in early psoriatic arthritis: an open-label extension of a randomized placebo-controlled trial

BackgroundIf TNF inhibitors are initiated in the early stages of psoriatic arthritis, this could potentially modulate disease and therefore allow us to discontinue the TNF inhibitor after achieving remission.ObjectiveTo investigate whether remission induced by tumour necrosis factor alpha inhibitor (TNFi) and methotrexate in patients with early psoriatic arthritis is sustained after withdrawal of TNFi.MethodsOpen-label extension of a recently published double-blind, randomized placebo-controlled trial. Patients with psoriatic arthritis fulfilling the CASPAR criteria and with active disease at baseline (swollen and tender joint count ≥ 3) were randomized to either golimumab and methotrexate or matched placebo and methotrexate. Patients in Disease Activity Score (DAS) remission at week 22 continued in the open-label extension on methotrexate monotherapy. The primary end point was the percentage of patients in DAS-CRP remission (DAS < 1.6) at week 50.ResultsEight patients from the original placebo group and 18 patients from the original TNFi group continued in the extension phase. At week 50, 6 out of 8 (75%) patients from the original MTX (methotrexate) group versus 10 out of 18 (56%) patients from the original MTX+TNFi group were in DAS-CRP remission (p = 0.347). Considering the total study population, 6 out of 24 (25%) of the original MTX group versus 10 out of 26 (38.5%) of the original MTX+TNFi group were in DAS remission at week 50 (p = 0.308).ConclusionsRemission achieved by initial combination treatment with TNFi and methotrexate in early psoriatic arthritis is maintained on methotrexate monotherapy in approximately half of the patients.Trial registrationRegistered at Clinicaltrials.gov with number NCT01871649 on June 7, 2013.

Achieving remission in psoriatic arthritis by early initiation of TNF inhibition: a double-blind, randomised, placebo-controlled trial of golimumab plus methotrexate versus placebo plus methotrexate

Assessing prognosis and prediction of treatment response in early rheumatoid arthritis: systematic reviews.

Rheumatoid arthritis (RA) is a chronic, debilitating disease associated with reduced quality of life and substantial costs. It is unclear which tests and assessment tools allow the best assessment of prognosis in people with early RA and whether or not variables predict the response of patients to different drug treatments. To systematically review evidence on the use of selected tests and assessment tools in patients with early RA (1) in the evaluation of a prognosis (review 1) and (2) as predictive markers of treatment response (review 2). Electronic databases (e.g. MEDLINE, EMBASE, The Cochrane Library, Web of Science Conference Proceedings; searched to September 2016), registers, key websites, hand-searching of reference lists of included studies and key systematic reviews and contact with experts. Review 1 - primary studies on the development, external validation and impact of clinical prediction models for selected outcomes in adult early RA patients. Review 2 - primary studies on the interaction between selected baseline covariates and treatment (conventional and biological disease-modifying antirheumatic drugs) on salient outcomes in adult early RA patients. Review 1 - 22 model development studies and one combined model development/external validation study reporting 39 clinical prediction models were included. Five external validation studies evaluating eight clinical prediction models for radiographic joint damage were also included. c-statistics from internal validation ranged from 0.63 to 0.87 for radiographic progression (different definitions, six studies) and 0.78 to 0.82 for the Health Assessment Questionnaire (HAQ). Predictive performance in external validations varied considerably. Three models [(1) Active controlled Study of Patients receiving Infliximab for the treatment of Rheumatoid arthritis of Early onset (ASPIRE) C-reactive protein (ASPIRE CRP), (2) ASPIRE erythrocyte sedimentation rate (ASPIRE ESR) and (3) Behandelings Strategie (BeSt)] were externally validated using the same outcome definition in more than one population. Results of the random-effects meta-analysis suggested substantial uncertainty in the expected predictive performance of models in a new sample of patients. Review 2 - 12 studies were identified. Covariates examined included anti-citrullinated protein/peptide anti-body (ACPA) status, smoking status, erosions, rheumatoid factor status, C-reactive protein level, erythrocyte sedimentation rate, swollen joint count (SJC), body mass index and vascularity of synovium on power Doppler ultrasound (PDUS). Outcomes examined included erosions/radiographic progression, disease activity, physical function and Disease Activity Score-28 remission. There was statistical evidence to suggest that ACPA status, SJC and PDUS status at baseline may be treatment effect modifiers, but not necessarily that they are prognostic of response for all treatments. Most of the results were subject to considerable uncertainty and were not statistically significant. The meta-analysis in review 1 was limited by the availability of only a small number of external validation studies. Studies rarely investigated the interaction between predictors and treatment. Collaborative research (including the use of individual participant data) is needed to further develop and externally validate the clinical prediction models. The clinical prediction models should be validated with respect to individual treatments. Future assessments of treatment by covariate interactions should follow good statistical practice. Review 1 - uncertainty remains over the optimal prediction model(s) for use in clinical practice. Review 2 - in general, there was insufficient evidence that the effect of treatment depended on baseline characteristics. This study is registered as PROSPERO CRD42016042402.

Serum matrix metalloproteinase 3 levels are associated with an effect of iguratimod as add-on therapy to biological DMARDs in patients with rheumatoid arthritis.

ObjectiveThe aim of this study was to clarify whether serum matrix metalloproteinase 3 (MMP-3) levels are associated with an effect of iguratimod as add-on therapy to biological DMARDs (bDMARDs) in patients with rheumatoid arthritis (RA).MethodsForty three patients with RA were treated with iguratimod as add-on therapy to bDMARDs. They were classified into remission and non-remission groups at 24 weeks of iguratimod therapy. Remission was defined as a state with a disease activity score (DAS) <2.6 in 28 joints (termed DAS remission) and total power Doppler ultrasound (US) score <3 (termed US remission). The serum MMP-3 levels at baseline and at 12 weeks were compared between these two groups.ResultsThere were no significant differences in the serum MMP-3 levels at baseline between the DAS and US remission groups and the non-remission group. The serum MMP-3 levels at 12 weeks in the US remission group were significantly lower than those in the non-remission group. The ratios of the serum MMP-3 levels at baseline to those at 12 weeks in both the DAS and US remission groups were significantly lower than those in the non-remission group. An MMP-3 ratio <0.86 was determined as the cut-off value to predict US remission at 24 weeks.ConclusionOur findings suggest that the ratios of the serum MMP-3 levels at baseline to those at 12 weeks could be used to predict remission in RA patients who are administered iguratimod as an add-on to bDMARDs.

Comparative Analysis and Predictors of 10-year Tumor Necrosis Factor Inhibitors Drug Survival in Patients with Spondyloarthritis: First-year Response Predicts Longterm Drug Persistence

To evaluate the 10-year drug survival of the first tumor necrosis factor inhibitor (TNFi) administered to patients with spondyloarthritis (SpA) overall and comparatively between SpA subsets, and to identify predictors of drug retention. Patients with SpA in the Hellenic Registry of Biologic Therapies, a prospective multicenter observational cohort, starting their first TNFi between 2004-2014 were analyzed. Kaplan-Meier curves and Cox regression models were used. Overall, 404 out of 1077 patients (37.5%) discontinued treatment (followup: 4288 patient-yrs). Ten-year drug survival was 49%. In the unadjusted analyses, higher TNFi survival was observed in patients with ankylosing spondylitis (AS) compared to undifferentiated SpA and psoriatic arthritis [PsA; significant beyond the first 2.5 (p = 0.003) years and 7 years (p < 0.001), respectively], and in patients treated for isolated axial versus peripheral arthritis (p = 0.001). In all multivariable analyses, male sex was a predictor for longer TNFi survival. Use of methotrexate (MTX) was a predictor in PsA and in patients with peripheral arthritis. Absence of peripheral arthritis and use of a monoclonal antibody (as opposed to non-antibody TNFi) independently predicted longer TNFi survival in axial disease because of lower rates of inefficacy. Achievement of major responses during the first year in either axial or peripheral arthritis was the strongest predictor of longer therapy retention (HR 0.33, 95% CI 0.26-0.41 for Ankylosing Spondylitis Disease Activity Score inactive disease, and HR 0.35, 95% CI 0.24-0.50 for 28-joint Disease Activity Score remission). The longterm retention of the first TNFi administered to patients with SpA is high, especially for males with axial disease. The strongest predictor of longterm TNFi survival is a major response within the first year of treatment.

Starting of biological disease modifying antirheumatic drugs may be postponed in rheumatoid arthritis patients with multimorbidity: Single center real life results.

The objective of this study was to assess the frequency of comorbidities and multimorbidities in rheumatoid arthritis (RA) patients under biologic therapy and their effects on biological disease modifying antirheumatic drugs (DMARDs) choice, timing, and response.Hacettepe University Biologic Registry (HUR-BIO) is single center biological DMARD registry. Cardiovascular, infectious, cancer, and other comorbidities were recorded with face to face interviews. Multimorbidity is defined as >1 comorbidity. Disease duration, initial date of biological DMARDs, initial and overall biological DMARD choice were recorded. Disease activity score-28 (DAS-28) responses were compared to comorbidity presence and multimorbidity.Total of 998 RA patients were enrolled into the study. The mean age was 53.1 (12.5) and mean disease duration (standard deviation [SD]) was 11.7 (7.5) years. At least 1 comorbidity was detected in 689 (69.1%) patients, 375 (37.9%) patients had multimorbidity. Patients had mean 1.36 ± 1.32 comorbidity. The median durations of first biological DMARDs prescription were 60 (3–552) months after RA diagnosis. For multimorbidity patients, the median first biological prescription duration was longer than the duration for patients without multimorbidity (72 [3–552] vs 60 [3–396] months, P < .001). The physicians prescribe tumor necrosis factor inhibitor (TNFi) biological drugs less frequently than other biological DMARDs in patients with at least 1 comorbidity (66.2% vs 74.5%, P = .007) or multimorbidity (34.6% vs 43.5%, P = .006). Patients with comorbidities and multimorbidity achieved DAS-28 remission less frequently than patients without comorbidity (31.6% vs 42.6%, P = .012 and 27.2% vs 39.7%, P = .001, respectively).In real life, physicians may postpone to prescribe biological DMARDs and less frequently choose TNFi biological drugs in patients with multimorbidity. Furthermore, comorbidity may have a negative effect on the treatment response.

Sarilumab: Review of a Second IL-6 Receptor Antagonist Indicated for the Treatment of Rheumatoid Arthritis.

PubMed (1966 to January 2018), Clinicaltrials.gov (January 2018), and Scopus (1970 to January 2018) were searched using sarilumab, Kevzara, REGN88, and SAR153191. Human studies published in peer-reviewed publications in English were the primary sources for efficacy and safety. Data from randomized, double-blind, controlled, published clinical studies weeks demonstrated statistically significantly higher American College of Rheumatology (ACR) 20, ACR50, and Disease Activity Score-28 (DAS28) remission response rates and improvements in DAS28 and Health Assessment Questionnaire-Disability Index scores for sarilumab monotherapy versus adalimumab monotherapy (P < 0.05) and for sarilumab versus placebo in patients receiving methotrexate or other conventional synthetic disease-modifying antirheumatic drugs (DMARDs); P < 0.05. The ACR20 and ACR50 response rates were, respectively, 56-72% and 35-46% for sarilumab, 58% and 30% for adalimumab, and 33-34% and 15-18% for placebo. DAS28 remission rates were 20-34% for sarilumab, 7% for adalimumab, and 7-10% for placebo. Sarilumab has a higher risk for neutropenia than tocilizumab, the other IL-6 inhibitor, but a lower risk for dyslipidemia, injection site reactions, and gastrointestinal perforation. The acquisition costs of sarilumab are expected to be similar to those of most other biologic DMARDs. Sarilumab is an alternative to biologic DMARDs or targeted synthetic DMARDs in patients with moderate to severely active RA who have not responded adequately to prior conventional synthetic DMARDs or tumor necrosis factor-α inhibitors.

AC-CUTE: An Open-Label Study to Evaluate Progression of Structural Joint Damage and Inflammation in Subjects with Moderate to Severe Rheumatoid Arthritis.

Aim Examine the efficacy of once-weekly subcutaneous tocilizumab (SC-TCZ) on joint damage at 24 weeks based on radiography of the hands and feet and magnetic resonance imaging (MRI) of the hand in subjects with moderate to severe rheumatoid arthritis (RA). Methods In this Australian open-label, multicentre, prospective, single-arm study, subjects received 162 mg SC-TCZ weekly. Primary endpoint was change in radiographic Genant-modified Total Sharp Score (TSS) between baseline and Week 24. Secondary endpoints included change from baseline to Week 24 in RA MRI scoring (RAMRIS) of erosions, synovitis, and osteitis and Cartilage Loss Score (CARLOS) in the dominant hand and disease activity score 28 (DAS28). Results 52 subjects were enrolled (80% female, mean (SD) age 57 (12) years). Radiography showed mild but not significant progression of joint damage (mean (SD) change in TSS 0.46 (1.29)). Synovitis reduced significantly on MRI; however, osteitis, erosion, and cartilage loss did not change significantly. DAS28 improved significantly by Week 24; 78% of subjects achieved DAS28 remission. SC-TCZ was generally well tolerated. Conclusion Synovitis and DAS28 decreased significantly; however, no significant change in osteitis or joint damage was observed at Week 24. Trial registration This trial is registered with Clinicaltrials.gov registration number NCT01951170 (ML28703).
