Efficacy and safety of tacrolimus versus corticosteroid as initial monotherapy in adult-onset minimal change disease: a meta-analysis

Objective The objective of this meta-analysis was to compare the efficacy and safety of tacrolimus (TAC) monotherapy versus corticosteroid as initial monotherapy in adult-onset minimal change disease (MCD) patients. Methods Databases including PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, and Wanfang database were searched from the inception to March 20, 2021. Eligible studies comparing TAC monotherapy and corticosteroid as initial monotherapy for adult-onset MCD patients were included. Data were analyzed using Review Manager Version 5.3. Results Four randomized controlled trials (RCTs) involving 196 patients were included in the meta-analysis. For initial monotherapy for adult-onset MCD, TAC and corticosteroid had similar complete remission (OR 1.06, 95% CI 0.47–2.41, P = 0.89), total remission (OR 1.30, 95% CI 0.39–4.35, P = 0.67), relapse rate (OR 0.63, 95% CI 0.28–1.42, P = 0.26). Main drug-related adverse effects of two therapeutic regimens had no difference concerning infection (OR 0.54, 95% CI 0.23–1.27, P = 0.15), glucose intolerance (OR 0.55, 95% CI 0.16–1.84, P = 0.33) and acute renal failure (OR 1.37, 95% CI 0.36–7.31, P = 0.71). Conclusion TAC monotherapy is comparable with corticosteroid monotherapy in initial therapy of MCD. To further confirm the conclusion, more large multicenter RCTs are necessary.
