EULAR recommendations for the management of rheumatoid arthritis with synthetic and biological disease-modifying antirheumatic drugs

Treatment of rheumatoid arthritis (RA) may differ among rheumatologists and currently, clear and consensual international recommendations on RA treatment are not available. In this paper recommendations for the treatment of RA with synthetic and biological disease-modifying antirheumatic drugs (DMARDs) and glucocorticoids (GCs) that also account for strategic algorithms and deal with economic aspects, are described. The recommendations are based on evidence from five systematic literature reviews (SLRs) performed for synthetic DMARDs, biological DMARDs, GCs, treatment strategies and economic issues. The SLR-derived evidence was discussed and summarised as an expert opinion in the course of a Delphi-like process. Levels of evidence, strength of recommendations and levels of agreement were derived. Fifteen recommendations were developed covering an area from general aspects such as remission/low disease activity as treatment aim via the preference for methotrexate monotherapy with or without GCs vis-à-vis combination of synthetic DMARDs to the use of biological agents mainly in patients for whom synthetic DMARDs and tumour necrosis factor inhibitors had failed. Cost effectiveness of the treatments was additionally examined. These recommendations are intended to inform rheumatologists, patients and other stakeholders about a European consensus on the management of RA with DMARDs and GCs as well as strategies to reach optimal outcomes of RA, based on evidence and expert opinion.

European League Against Rheumatism recommendations for the management of psoriatic arthritis with pharmacological therapies

Background Psoriatic arthritis (PsA) is a clinically heterogeneous disease. Clear consensual treatment guidance focused on the musculoskeletal manifestations of PsA would be advantageous. The authors present European League Against Rheumatism (EULAR) recommendations for the treatment of PsA with systemic or local (non-topical) symptomatic and disease-modifying antirheumatic drugs (DMARD). Methods The recommendations are based on evidence from systematic literature reviews performed for non-steroidal anti-inflammatory drugs (NSAID), glucocorticoids, synthetic DMARD and biological DMARD. This evidence was discussed, summarised and recommendations were formulated by a task force comprising 35 representatives, and providing levels of evidence, strength of recommendations and levels of agreement. Results Ten recommendations were developed for treatment from NSAID through synthetic DMARD to biological agents, accounting for articular and extra-articular manifestations of PsA. Five overarching principles and a research agenda were defined. Conclusion These recommendations are intended to provide rheumatologists, patients and other stakeholders with a consensus on the pharmacological treatment of PsA and strategies to reach optimal outcomes, based on combining evidence and expert opinion. The research agenda informs directions within EULAR and other communities interested in PsA.

Diagnostic and predictive value of anti-cyclic citrullinated protein antibodies in rheumatoid arthritis: a systematic literature review

Objective: To evaluate the two generations of anti-cyclic citrullinated protein (CCP) antibodies as a diagnostic marker of rheumatoid arthritis (RA) and as a predictor of future development of RA in healthy subjects and in patients with early undifferentiated arthritis. Methods: A systematic analysis of the literature published between 1999 and February 2006 was conducted. Data were collected on the sensitivity and specificity of the two generations of anti-CCP antibodies for diagnosing RA and predicting future development of the disease. Results: Among 107 studies initially identified, 68 had interpretable data and were analysed. Diagnostic properties were assessed in 58 studies: mean (SD) sensitivity was 53 (10)% (range 41–68) and 68 (15)% (range 39–94) for anti-CCP1 and anti-CCP2, respectively; mean (SD) specificity was 96 (3)% (range 90–99) and 95 (5)% (range 81–100) for anti-CCP1 and anti-CCP2, respectively. Predictive properties were assessed in 14 studies; odds ratio (95% confidence interval) of anti-CCP1 and anti-CCP2 for the future development of RA were 20 (14 to 31) and 25 (18 to 35), respectively, among patients with early undifferentiated arthritis and 64.5 (8.5 to 489) and 28 (8 to 95), respectively, among healthy subjects. Conclusion: Sensitivity of the second generation of anti-CCP is close to that of rheumatoid factor, with a higher specificity, for distinguishing RA from other rheumatic diseases. Moreover, anti-CCP antibodies appear to be highly predictive of the future development of RA in both healthy subjects and patients with undifferentiated arthritis.

Risk of serious infections during rituximab, abatacept and anakinra treatments for rheumatoid arthritis: meta-analyses of randomised placebo-controlled trials

Background: Tumour necrosis factor α blockers in rheumatoid arthritis are known to increase the risk of serious infections defined as life-threatening, requiring hospitalisation or intravenous antibiotics. Recently, new biological agents have become available. Their safety is an important issue. Purpose: To assess if biological agents, ie rituximab, abatacept and anakinra increase the risk of serious infections in patients with rheumatoid arthritis in published randomised controlled trials. Data source: A systematic review of the literature using PUBMED, EMBASE, Cochrane library and abstracts databases (American College of Rheumatology and European League Against Rheumatism annual meetings) was performed up to October 2007. This search was completed with data from the Food and Drug Administration, the European Agency for the Evaluation of Medicinal Products and manufacturers. Data extraction: Three fixed-effect meta-analyses were performed to compare serious infection rates between each biological agent and placebo. Pooled odds ratios (ORs) were calculated, using the Mantel–Haenszel method with a continuity correction. Data synthesis: Twelve randomised controlled trials with data concerning serious infections were analysed (three for rituximab, five for abatacept and four for anakinra). They included 745 patients, 1960 patients, 2062 patients and 2112 patients treated by rituximab, abatacept, anakinra and placebo respectively. The overall pooled ORs did not reveal a statistically significant increased risk of serious infection for abatacept and rituximab; this risk was increased for high doses of anakinra (⩾100 mg daily) versus low dose and placebo (ORs = 9.63 (95% CI, 1.31 to 70.91) and 3.40 (95% CI, 1.11 to 10.46) respectively). Conclusions: These meta-analyses did not reveal a significant increase in the risk of serious infections during rituximab or abatacept treatments in patients with rheumatoid arthritis; however, high doses of anakinra may increase this risk, especially when patients have comorbidity factors. Large studies must be performed to confirm this safety profile in daily practice.

Safety of synthetic and biological DMARDs: a systematic literature review informing the 2013 update of the EULAR recommendations for management of rheumatoid arthritis

Objectives To update the evidence for the safety of synthetic disease-modifying antirheumatic drugs (sDMARDs), glucocorticoids (GC) and biological DMARDs (bDMARDs) in patients with rheumatoid arthritis (RA) to inform the European League Against Rheumatism (EULAR) recommendations for the management of RA. Methods Systematic literature review (SLR) of observational studies (including registries). Interventions were any bDMARD (anakinra, infliximab, etanercept, adalimumab, rituximab, abatacept, tocilizumab, golimumab or certolizumab pegol) or sDMARD (methotrexate, leflunomide, hydroxychloroquine, sulfasalazine, gold/auranofin, azathioprine, chlorambucil, chloroquine, cyclosporin, cyclophosphamide, mycophenolate, minocycline, penicillamine, tacrolimus or tofacitinib) and a comparator was required. Information on GCs was collected from the included studies. All safety outcomes were included. Results Forty-nine observational studies addressing diverse safety outcomes of therapy with bDMARDs met eligibility criteria. Substantial heterogeneity precluded meta-analysis of any of the outcomes. Patients on tumour necrosis factor inhibitors (TNFi) compared to patients on conventional sDMARDs had a higher risk of serious infections (adjusted HR (aHR) 1.1–1.8), a higher risk of tuberculosis, and an increased risk of infection by herpes zoster cannot be excluded. Patients on TNFi did not have an increased risk for malignancies in general, lymphoma or non-melanoma skin cancer, but the risk of melanoma may be slightly increased (aHR 1.5). From the studies identified on conventional sDMARDs, no new safety signals were found. Conclusions The findings from this SLR confirm the known safety pattern of sDMARDs and bDMARDs for the treatment of RA.

Treating spondyloarthritis, including ankylosing spondylitis and psoriatic arthritis, to target: recommendations of an international task force

Background Therapeutic targets have been defined for diseases like diabetes, hypertension or rheumatoid arthritis and adhering to them has improved outcomes. Such targets are just emerging for spondyloarthritis (SpA). Objective To define the treatment target for SpA including ankylosing spondylitis and psoriatic arthritis (PsA) and develop recommendations for achieving the target, including a treat-to-target management strategy. Methods Based on results of a systematic literature review and expert opinion, a task force of expert physicians and patients developed recommendations which were broadly discussed and voted upon in a Delphi-like process. Level of evidence, grade and strength of the recommendations were derived by respective means. The commonalities between axial SpA, peripheral SpA and PsA were discussed in detail. Results Although the literature review did not reveal trials comparing a treat-to-target approach with another or no strategy, it provided indirect evidence regarding an optimised approach to therapy that facilitated the development of recommendations. The group agreed on 5 overarching principles and 11 recommendations; 9 of these recommendations related commonly to the whole spectrum of SpA and PsA, and only 2 were designed separately for axial SpA, peripheral SpA and PsA. The main treatment target, which should be based on a shared decision with the patient, was defined as remission, with the alternative target of low disease activity. Follow-up examinations at regular intervals that depend on the patients status should safeguard the evolution of disease activity towards the targeted goal. Additional recommendations relate to extra-articular and extramusculoskeletal aspects and other important factors, such as comorbidity. While the level of evidence was generally quite low, the mean strength of recommendation was 9–10 (10: maximum agreement) for all recommendations. A research agenda was formulated. Conclusions The task force defined the treatment target as remission or, alternatively, low disease activity, being aware that the evidence base is not strong and needs to be expanded by future research. These recommendations can inform the various stakeholders about expert opinion that aims for reaching optimal outcomes of SpA.

Efficacy of biological disease-modifying antirheumatic drugs: a systematic literature review informing the 2013 update of the EULAR recommendations for the management of rheumatoid arthritis

Objectives To update the evidence for the efficacy of biological disease-modifying antirheumatic drugs (bDMARD) in patients with rheumatoid arthritis (RA) to inform the European League Against Rheumatism(EULAR) Task Force treatment recommendations. Methods Medline, Embase and Cochrane databases were searched for articles published between January 2009 and February 2013 on infliximab, etanercept, adalimumab, certolizumab-pegol, golimumab, anakinra, abatacept, rituximab, tocilizumab and biosimilar DMARDs (bsDMARDs) in phase 3 development. Abstracts from 2011 to 2012 American College of Rheumatology (ACR) and 2011–2013 EULAR conferences were obtained. Results Fifty-one full papers, and 57 abstracts were identified. The randomised controlled trials (RCT) confirmed the efficacy of bDMARD+conventional synthetic DMARDs (csDMARDs) versus csDMARDs alone (level 1B evidence). There was some additional evidence for the use of bDMARD monotherapy, however bDMARD and MTX combination therapy for all bDMARD classes was more efficacious (1B). Clinical and radiographic responses were high with treat-to-target strategies. Earlier improvement in signs and symptoms were seen with more intensive initial treatment strategies, but outcomes were similar upon addition of bDMARDs in patients with insufficient response to MTX. In general, radiographic progression was lower with bDMARD use, mainly due to initial treatment effects. Although patients may achieve bDMARD- and drug-free remission, maintenance of clinical responses was higher with bDMARD continuation (1B), but bDMARD dose reduction could be applied (1B). There was still no RCT data for bDMARD switching. Conclusions The systematic literature review confirms efficacy of biological DMARDs in RA. It addresses different treatment strategies with the potential for reduction in therapy, particularly with early disease control, and highlights emerging therapies.

European League Against Rheumatism (EULAR) recommendations for the management of psoriatic arthritis with pharmacological therapies: 2015 update

Background Since the publication of the European League Against Rheumatism recommendations for the pharmacological treatment of psoriatic arthritis (PsA) in 2012, new evidence and new therapeutic agents have emerged. The objective was to update these recommendations. Methods A systematic literature review was performed regarding pharmacological treatment in PsA. Subsequently, recommendations were formulated based on the evidence and the expert opinion of the 34 Task Force members. Levels of evidence and strengths of recommendations were allocated. Results The updated recommendations comprise 5 overarching principles and 10 recommendations, covering pharmacological therapies for PsA from non-steroidal anti-inflammatory drugs (NSAIDs), to conventional synthetic (csDMARD) and biological (bDMARD) disease-modifying antirheumatic drugs, whatever their mode of action, taking articular and extra-articular manifestations of PsA into account, but focusing on musculoskeletal involvement. The overarching principles address the need for shared decision-making and treatment objectives. The recommendations address csDMARDs as an initial therapy after failure of NSAIDs and local therapy for active disease, followed, if necessary, by a bDMARD or a targeted synthetic DMARD (tsDMARD). The first bDMARD would usually be a tumour necrosis factor (TNF) inhibitor. bDMARDs targeting interleukin (IL)12/23 (ustekinumab) or IL-17 pathways (secukinumab) may be used in patients for whom TNF inhibitors are inappropriate and a tsDMARD such as a phosphodiesterase 4-inhibitor (apremilast) if bDMARDs are inappropriate. If the first bDMARD strategy fails, any other bDMARD or tsDMARD may be used. Conclusions These recommendations provide stakeholders with an updated consensus on the pharmacological treatment of PsA and strategies to reach optimal outcomes in PsA, based on a combination of evidence and expert opinion.

A systematic literature review of drug therapies for the treatment of psoriatic arthritis: current evidence and meta-analysis informing the EULAR recommendations for the management of psoriatic arthritis

Objectives To review the available evidence for the efficacy and safety of non-steroidal anti-inflammatory drugs (NSAIDs), synthetic and biological drug therapies for the different clinical manifestations of psoriatic arthritis (PsA) in order to provide data for the development of treatment recommendations by the European League Against Rheumatism (EULAR) taskforce. Methods A systematic literature review (SLR) of available treatments for PsA was performed using the largest electronic databases (MEDLINE, EMBASE and COCHRANE) by two working groups formed within the EULAR taskforce. This comprised a comprehensive sample of rheumatologists, dermatologists, epidemiologists and patients. The available evidence was reviewed for NSAIDs, synthetic disease modifying antirheumatic drugs (DMARDs), local and systemic corticosteroids and biologic drugs. All articles and abstracts published between 1962 and January 2010 were reviewed and considered and a meta-analysis of data on biological therapies was performed. Results While little data are available on NSAIDs, glucocorticoids and synthetic DMARDs, the available evidence suggests an acceptable efficacy and safety profile of both NSAIDs and synthetic DMARDs (methotrexate, cyclosporine A, sulfasalazine and leflunomide) in PsA. More evidence is available (level 1B) supporting the efficacy of anti-tumour necrosis factor (anti-TNF) agents (adalimumab, etanercept, golimumab and infliximab) in treating the signs and symptoms of PsA as well as reducing radiographic progression. Registry data show no new safety concerns, although the numbers studied to date are relatively small. Conclusions This SLR reveals some evidence to support the use of NSAIDs and synthetic DMARDs and good evidence for the efficacy of anti-TNF therapy in PsA.

QUEST-RA: quantitative clinical assessment of patients with rheumatoid arthritis seen in standard rheumatology care in 15 countries.

Objective: To conduct a cross-sectional review of non-selected consecutive outpatients with rheumatoid arthritis (RA) as part of standard clinical care in 15 countries for an overview of the characteristics of patients with RA. Methods: The review included current disease activity using data from clinical assessment and a patient self-report questionnaire, which was translated into each language. Data on demographic, disease and treatment-related variables were collected and analysed using descriptive statistics. Variation in disease activity on DAS28 (disease activity score on 28-joint count) within and between countries was graphically analysed. A median regression model was applied to analyse differences in disease activity between countries. Results: Between January 2005 and October 2006, the QUEST-RA (Quantitative Patient Questionnaires in Standard Monitoring of Patients with Rheumatoid Arthritis) project included 4363 patients from 48 sites in 15 countries; 78% were female, >90% Caucasian, mean age was 57 years and mean disease duration was 11.5 years. More than 80% of patients had been treated with methotrexate in all but three countries. Overall, patients had an active disease with a median DAS28 of 4.0, with a significant variation between countries (p<0.001). Among 42 sites with >50 patients included, low disease activity of DAS28 ⩽3.2 was found in the majority of patients in seven sites in five countries; in eight sites in five other countries, >50% of patients had high disease activity of DAS28 >5.1. Conclusions: This international multicentre cross-sectional database provides an overview of clinical status and treatments of patients with RA in standard clinical care in 2005–6 including countries that are infrequently involved in clinical research projects.
