Objectives: The aim of this systematic review was to inform the update of European League Against Rheumatism (EULAR) Recommendations for the management of Behçet's syndrome (BS), on the evidence for the treatment of skin, mucosa and joint involvement of BS., Methods: A systematic literature search, data extraction, statistical analyses and assessment of the quality of evidence were performed according to a pre-specified protocol using the PRISMA guidelines. Studies that assessed the efficacy of an intervention in comparison to an active comparator or placebo for oral ulcers, genital ulcers, papulopustular lesions, nodular lesions or arthritis were included. Where possible, risk ratios were calculated for binary outcomes and mean difference for continuous outcomes., Results: Among the 3927 references that were screened, 37 were included in the analyses. Twenty-seven of these assessed mucocutaneous and 17 assessed joint involvement. Twenty-one of these studies were randomised controlled trials (RCTs). RCTs with colchicine, azathioprine, interferon-alpha, thalidomide, etanercept and apremilast showed beneficial results with some differences according to lesion type and gender. These agents were generally well tolerated with few adverse events causing withdrawal from the study., Conclusions: RCTs comprised more than a half (21/37, 57%) of the sources included in the evidence synthesis related to skin, mucosa and joint involvement applicable for the EULAR Recommendations for the management of BS. Differences in the outcome measures that were used across the included studies often made it difficult to combine and compare the results., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Objective: To assess the efficacy and safety of treatment modalities for major organ involvement of Behçet's syndrome (BS), in order to inform the update of the EULAR recommendations for the management of BS., Methods: A systematic literature review of all randomized controlled trials, controlled clinical trials, or open label trials assessing eye, vascular, nervous system or gastrointestinal system involvement of BS was performed. If controlled trials were not available for answering a specific research question, uncontrolled studies or case series were also included., Results: We reviewed the titles and abstracts of 3927 references and 161 studies met our inclusion criteria. There were only nine randomized controlled trials. Observational studies with IFN-α and monoclonal anti-TNF antibodies showed beneficial results for refractory uveitis. Meta-analysis of case-control studies showed that immunosuppressives decreased the recurrence rate of deep vein thrombosis significantly whereas anticoagulants did not. CYC and high dose glucocorticoids decreased mortality in pulmonary arterial aneurysms and postoperative complications in peripheral artery aneurysms. Beneficial results for gastrointestinal involvement were obtained with 5-ASA derivatives and AZA as first line treatment and with thalidomide and/or monoclonal anti-TNF antibodies in refractory cases. Observational studies for nervous system involvement showed improved outcome with immunosuppressives and glucocorticoids. Meta-analysis of case-control studies showed an increased risk of developing nervous system involvement with ciclosporin-A., Conclusion: The majority of studies related to major organ involvement that informed the updated EULAR recommendations for the management of BS were observational studies.

We studied a well-selected population of patients with active rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) without immunosuppressive therapy. Control and patient peripheral blood mononuclear cells (PBMC) were incubated with IL-1β, IL-10, TGF-β or LPS for 20 h and the in vitro basal and stimulated secretions of IL-6, TNF-α, IL-1β and IL-1ra were measured by ELISA. We found that in the SLE patients the basal secretion of IL-6 was significantly lower and that of IL-1ra significantly higher than in control subjects, while in the RA group the basal IL-1ra secretion was higher than in healthy subjects. SLE and RA PBMC responded to LPS and IL-1β reaching higher cytokine secretion values than controls. The in vitro response of SLE and RA PBMC to TGFβ was normal, while that to IL-10 was defective: IL-10 was able to stimulate the production of IL-6 and IL-1ra in PBMC from normal subjects, but it was unable to enhance IL-6 secretion in RA cells and it was also completely ineffective in inducing IL-1ra secretion in both SLE and RA PBMC. Our work add new data useful for the evaluation of IL-10 and IL-1ra as therapeutic agents in rheumatic diseases. [ABSTRACT FROM AUTHOR]
