| Sumario: | Background: A considerable number of patients with myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD) will experience a relapse, but the effect of maintenance therapies on re-attack rates is currently unknown. Objective: To investigate the efficacy and safety of immunosuppressive therapy for preventing disease relapses in patients with MOGAD, including rituximab (RTX), mycophenolate mofetil (MMF), and azathioprine (AZA). Methods: English-language studies published prior to August 31, 2020, were searched in the NCBI (PubMed), ISI Web of Science, and the Cochrane Library databases. Patient characteristics, treatment regimens, outcome measures, and adverse effects were retrieved. Results: We enrolled 11 studies in the final meta-analysis, including 346 patients with MOGAD. RTX therapy was demonstrated to result in reduced mean annualized relapse rate (ARR) by 1.35 (95% confidence interval (CI): 0.85–1.85) and reduced mean Expanded Disability Status Scale score by 0.80 (95% CI: 0.53–1.08) in patients with MOGAD. MMF therapy was associated with the mean ARR decreasing by 0.83 (95% CI: 0.31–1.35), and AZA was related to the mean ARR decreasing by 1.71 (95% CI: 0.83–2.58). The reported discontinuation rates of RTX, MMF, and AZA therapy due to adverse effects were 3/197 (1.52%), 3/39 (7.69%), and 4/37 (10.81%), respectively. Conclusion: The study provided evidence to support the efficacy of RTX, MMF, and AZA on the preventive treatment in patients with MOGAD. However, large randomized controlled trials are still needed in the future. |
