The efficacy and safety of belimumab for SLE patients are not clear. Therefore, this meta-analysis is integrating the efficacy and safety of belimumab for patients with SLE. Methods PubMed, EMBASE, and Cochrane Library were searched for randomized clinical trials (RCTs) that studied the efficacy and safety of belimumab plus standard therapy before November 1, 2021. Data were pooled using the random-effects model and are expressed as risk ratios (RRs) or mean difference (MD) and corresponding 95% confidence intervals (CIs). Heterogeneity was assessed and quantified using I-2. Results Seven RCTs with 3,009 participants were included in this meta-analysis. Belimumab showed significantly decreased at least a 4-point improvement in Safety of Estrogen in Lupus National Assessment (SELENA)-Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score than placebo (RR, 1.32; 95% CI, 1.21-1.44; p < 0.001). However, belimumab significantly reduced the prednisone dose by 50% or more than placebo (RR, 1.59; 95% CI, 1.17-2.15; p = 0.003) and belimumab significantly increased the 36 Physical Component Summary (PCS) score (MD, 1.60; 95% CI, 0.30-2.90; p = 0.02). Regarding adverse events, there was no significant difference between the belimumab group and the control group. Conclusion The results suggest that belimumab plus standard therapy is more effective than placebo plus standard therapy in SLE patients. 收起
