Bone erosions and joint damage caused by chikungunya virus: a systematic review.

BACKGROUND: Chikungunya fever is an emerging global infection transmitted by Aedes mosquitoes that manifests as an acute febrile illness with joint pain and can lead to chronic arthritis. The mechanism underlying chronic joint damage remains unclear; however, chronic chikungunya arthritis shares similarities with rheumatoid arthritis. Disease-modifying antirheumatic drugs have revolutionized rheumatoid arthritis treatment by preventing joint damage. However, the role of these therapies in chronic chikungunya arthritis has not been determined. We conducted a systematic review to evaluate the burden of joint structural damage in chronic chikungunya arthritis to help to define the role of disease-modifying therapy in this disease. METHODS: This systematic review included retrospective and prospective studies, trials, and case reports evaluating joint damage caused by chikungunya virus. Various databases were searched without any date or language restrictions. Study selection was conducted independently by two researchers, and data were extracted from the articles selected. RESULTS: A total of 108 studies were initially evaluated, with 8 meeting the inclusion criteria. Longitudinal studies have reported persistent joint pain from chikungunya infection and the progression of radiographic joint damage up to 13 years post-infection. Joint imaging revealed synovial inflammation, bone erosion, and cartilage destruction in patients with chronic chikungunya arthritis. CONCLUSIONS: Few studies have addressed chikungunya-induced joint damage, limiting our understanding of chronic chikungunya arthritis. Nevertheless, chronic chikungunya arthritis has similarities to rheumatoid arthritis. The success of early disease-modifying antirheumatic drug therapy in rheumatoid arthritis underscores the need for comprehensive research on its role in chikungunya arthritis.

Chikungunya Arthritis Treatment with Methotrexate and Dexamethasone: A Randomized, Double-blind, Placebo-controlled Trial.

BACKGROUND: Chikungunya fever is a reemerging epidemic disease caused by a single-stranded RNA alphavirus transmitted throughout by Aedes mosquitoes. Chikungunya virus infection is a biphasic disease in which 72% to 95% of affected individuals manifest acute chikungunya fever. Following the acute phase, more than 40% of affected individuals develop arthritis, often lasting more than 3 months, referred to as chronic chikungunya arthritis, which frequently mimics rheumatoid arthritis. OBJECTIVE: This study aimed to evaluate the efficacy and safety of treatment of chronic chikungunya arthritis with methotrexate and dexamethasone in a randomized, double-blind, placebo-controlled clinical trial. METHODS: The patients were reassessed for treatment response by the DAS28-ESR, tender joint count and swollen joint count, Patient Global Assessment, and for secondary measures, including the Health Assessment Questionnaire Disability Index and Pain Visual Analog Scale. RESULTS: Thirty-one subjects were randomized (placebo, n = 16; methotrexate, n = 15); 27 completed treatment and 4 discontinued during the 8-week blinded period. Among the participants, 96.8% were female, with mean ± SD age was 52.9 ± 13. The mean ± SD disease duration prior to treatment was 220.9 ± 51.2 days. At 8 weeks, methotrexate-treated subjects showed a greater numerical trend towards improvement, but there were no significant differences between methotrexate- dexamethasone group and dexamethasone (placebo) group. CONCLUSION: In this relatively small cohort, all of whom received background dexamethasone, there was a greater numerical improvement trend in prespecified outcome measures, but methotrexate in combination with dexamethasone was not superior to dexamethasone in chronic chikungunya arthritis.
