Abstract
OBJECTIVE: Numerous studies have demonstrated the efficiency of tacrolimus + rituximab and rituximab in idiopathic membranous nephropathy (IMN). But optimal dosages of rituximab for IMN are still controversial. This network meta-analysis (NMA) was conducted to compare the efficacy of different rituximab dosages and other main treatments in IMN treatment. METHODS: Randomized controlled trials (RCTs) and observational studies analyzing nine therapeutic regimens for IMN were included from some databases. Network comparisons were performed to analyze the rates of total remission (TR) and relapse rate. The surface under the cumulative ranking area (SUCRA) was calculated to rank interventions. RESULTS: Twelve RCTs and 12 observational studies involving 1724 patients were pooled for comparison of 9 interventions. This NMA demonstrated steroids + tacrolimus was ranked first in the aspect of total remission at 6 months (92%) and 12 months (81.3%). The total remission rate associated with tacrolimus + rituximab increased rapidly between the sixth (SUCRA 22.5%) and the twelfth month (SUCRA 63.9%). Tacrolimus and cyclosporine A were associated with higher total remission at 6 months (78.8% and 65.4%, separately) and decreased at 12 months (58.1 and 34.9%, separately). Steroids + cyclophosphamide, rituximab (Heavy dose) and rituximab (Low dose) had stable remission rates at 6 (63.7%, 46.6%, and 19.4%) and 12 months (SUCRA 66.9%, 39.6%, and 28.8%). Tacrolimus and cyclosporine A were associated with a significantly higher risk of relapse than that with steroids + cyclophosphamide, rituximab (Heavy dose), and rituximab (Low dose). CONCLUSIONS: For IMN in adults, steroids + tacrolimus was ranked first in the aspect of total remission, followed by steroids + cyclophosphamide and steroids + cyclosporine A. The TR associated with rituximab (Heavy and Low dosage) at 12 months was higher than that at 6 months. And rituximab (Heavy dose) achieves a higher rate of total remission than that of rituximab (Low dose).
