BackgroudMycophenolate mofetil (MMF) has been recommended for the treatment of lupus nephritis (LN). Although inter-racial differences exist regarding the appropriate dose and efficacy of MMF in patients with LN, no definitive meta-analysis has yet been conducted in Chinese patients. This analysis investigated the efficacy and safety of MMF in Chinese patients with proliferative LN.MethodsA systematic literature search was conducted to select randomized controlled trials that reported at least one of the following: complete remission (CR), partial remission, total remission (TR; defined as complete remission + partial remission), relapse rate, serum creatinine, creatinine clearance, end-stage renal disease, death, infections, amenorrhea, leukopenia, alopecia, gastrointestinal symptoms, or liver damage.ResultsEighteen trials (927 patients) were included; 14 (750 patients) reported CR, partial remission, and TR. Two trials (58 patients) reported relapse rates during maintenance treatment. MMF induction significantly improved CR and TR vs cyclophosphamide (relative risk 1.34, 95% confidence interval: 1.13-1.58; P < .001; relative risk 1.16, 95% confidence interval: 1.02-1.33; P = .03), and was associated with significantly lower risks of infection (P < .001), amenorrhea (P < .001), leukopenia, and alopecia. No significant difference in relapse rate was evident between the MMF and azathioprine groups (P = .66).ConclusionAccording to this meta-analysis of 18 trials, MMF is significantly more effective than cyclophosphamide induction, and is associated with reduced incidences of infections, amenorrhea, leukopenia, and alopecia in Chinese patients with proliferative LN.
