In a systematic review and meta-analysis of randomized controlled trials (RCT), we aimed to evaluate the benefits and harms of all interventions for children with steroid-resistant nephrotic syndrome (SRNS). Nine RCTs involving 225 children were included. ⋯ No RCTs were identified comparing combination regimens comprising high-dose steroids, alkylating agents or cyclosporin with single agents, placebo, or no treatment. Further adequately powered and well-designed RCTs are needed to confirm the efficacy of cyclosporin and to evaluate regimens of high-dose steroids with alkylating agents or cyclosporin for SRNS.
