PG - 418-426 LID - S0025-7753(20)30657-6 [pii] LID - 10.1016/j.medcli.2020.07.039 [doi] AB - BACKGROUND: Idiopathic nephrotic syndrome is the most common glomerular disease in children, but there are still some difficulties in treating childhood steroid-dependent or steroid-resistant nephrotic syndrome (SDNS/SRNS). Rituximab (RTX) might be an effective and safe choice. METHODS: Studies were searched from PubMed, Web of Science, Cochrane library and some Chinese databases up to April 2020. Only randomized controlled trials (RCT) were included. RESULTS: Of 1383 screened articles, 6 RCTs with 334 participants were included. RTX was better than the control group at improving relapse-free rate in the short term [RR (risk ratio) (95% CI (confidence interval)), 1.84(1.41, 2.39)]. As for long-term, RTX did not show significant improvement [RR (95% CI), 4.43(.57, 34.67)]; but in subgroup analysis, RTX was still better than conventional drugs and tacrolimus [RR (95% CI), 9.91(1.95, 50.52) and 1.42(1.15, 1.75), respectively]. And there was a difference between the two groups of prednisolone dose after treatment [MD (mean difference) (95% CI), -.22(-.36, -.09) mg/kg/d)]. However, RTX did not significantly improve serum albumin and creatinine [MD (95% CI), 3.46(-1.40, 8.32)g/L and -3.66(-11.79, 4.48)mumol/L, respectively]. No significant differences between the RTX and the control group were found in total adverse events (AEs) or serious AEs. CONCLUSION: Childhood SDNS/SRNS patients appear to benefit from RTX in relapse-free rate and dose of prednisolone use. Also, RTX did not significantly increase the incidence of AEs. But RTX did not show improvements in biological indicators, more studies are required to explain the effect of RTX. CI - Copyright (c) 2020 Elsevier Espana, S.L.U. All rights reserved.
