Abstract
OBJECTIVE: Chikungunya virus infection is a rapidly emerging global viral infection that can cause chronic, debilitating arthritis that in some ways mimics rheumatoid arthritis. The aim of this study was to evaluate the available evidence regarding the efficacy and safety of methotrexate (MTX), a therapy that is widely used in rheumatoid arthritis, for the treatment of chronic chikungunya arthritis. METHODS: A systematic literature search was performed to identify all published trials that evaluated MTX as monotherapy or combination therapy in patients with chronic chikungunya arthritis. PubMed, SciELO, Scopus, and Cochrane Library databases were searched from study inception to August 2017. We also searched Google Scholar, the International Clinical Trials Registry Platform Search Portal, and clinicaltrials.gov. RESULTS: Among 131 possibly relevant studies, 6 met our criteria for evaluation: 4 were retrospective studies, 1 was a non-controlled prospective study, and 1 was an unblinded randomized clinical trial of combination MTX therapy. In the randomized clinical trial, triple therapy with MTX, hydroxychloroquine, and sulfasalazine was superior to hydroxychloroquine monotherapy, as assessed by the mean ± SD Disease Activity Score in 28 joints using the erythrocyte sedimentation rate (3.39 ± 0.87 versus 4.74 ± 0.65; P < 0.0001) and the Health Assessment Questionnaire score (1.14 ± 0.31 versus 1.88 ± 0.47; P < 0.0001). CONCLUSION: The number of available studies is limited, but taken together, these studies demonstrate that MTX is sufficiently efficacious to justify further study of MTX for the treatment of chronic chikungunya arthritis. The trials lacked rigorous study designs and used different treatment strategies and outcome measures. This systematic review underscores the need for randomized, prospective, placebo-controlled studies of MTX monotherapy for the treatment of chronic chikungunya arthritis.
