ObjectiveThe objective of this meta-analysis was to compare the efficacy and safety of tacrolimus (TAC) monotherapy versus TAC-corticosteroid combination therapy in idiopathic membranous nephropathy (IMN) patients.MethodsDatabases including PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, and Wanfang database were searched from inception to January 10, 2021. Eligible studies comparing TAC monotherapy and TAC-corticosteroid combination therapy in IMN patients were included. Data were analysed using Review Manager Version 5.3.ResultsSeven studies were included in the meta-analysis. One randomized controlled trial and six cohort studies involving 372 patients were identified. Compared with TAC monotherapy, TAC-corticosteroid had a higher total remission at the sixth month (odd ratio (OR) 0.49, 95% confidence interval (CI) 0.31-0.78, P < .01). The two therapy regimens had similar complete remission rates (OR 0.79, 95% CI 0.43-1.48, P = .47) at the sixth month and similar relapse rates (OR 1.44, 95% CI 0.70-2.92, P = .32). TAC-corticosteroid combination therapy had a higher incidence of infection (OR 0.38, 95% CI 0.18-0.81, P = .01). The two therapy regimens had similar incidences of gastrointestinal symptoms (OR 0.96, 95% CI 0.34-2.70, P = .93), abnormal aminotransferase (OR 0.90, 95% CI 0.34-2.38, P = .84), and glucose intolerance (OR 0.58, 95% CI 0.32-1.07, P = .08).ConclusionTAC-corticosteroid combination therapy had a higher total remission rate at the sixth month but had a higher incidence of infection than TAC monotherapy in the treatment of IMN. The two therapeutic regimens had similar relapse rates.Copyright © 2021 the Author(s). Published by Wolters Kluwer Health, Inc.
