Objective To systematically evaluate the effectiveness and safety of mycophenolate mofetil (MMF) for IgA Nephropathy (IgAN). Methods Databases including CNKI, CBM, MEDLINE, PubMed, The Cochrane Library and SCI were searched from January 1997 to January 2012, and the domestic conference data and relevant published articles were also searched manually. All randomized controlled trials (RCTs) on MMF in treating IgAN were independently collected and screened according to the inclusion and exclusion criteria by two reviewers. The data were extracted, the quality of the included studies was assessed and cross-checked, and then meta-analysis was conducted using RevMan 5.0 software. Results A total of 8 RCTs involving 272 patients with IgAN were included. The results of meta-analyses showed that: a) There were no significant differences in the overall effective rate (RR=0.72, 95%CI 0.21 to 2.52, P=0.61) between the MMF group and the placebo group, but the overall effective rate was higher in the MMF+hormone group than the CTX+hormone group (RR=4.21, 95%CI 1.86 to 9.53, Plt;0.000 1) and other immunosuppressants +hormone groups (RR=3.03, 95%CI 1.47 to 6.25, P=0.003); and b) Adverse reaction: The overall incidence rate of adverse reaction in the MMF+hormone group was lower than the CTX+hormone group (RR=0.16, 95%CI 0.07 to 0.37, Plt;0.000 1). There were no significant differences in the elevated serum creatinine rate (RR=2.28, 95%CI 0.65 to 7.94, P=0.20) and the case number of developing end-stage renal disease (ESRD) (RR=2.37, 95%CI 0.44 to 12.83, P=0.32) between the MMF group and the control group. Conclusion MMF combined with hormone in treating IgAN can increase the overall effective rate and decrease the overall incidence rate of adverse reaction, but its effectiveness of improving long-term survival rate has to be further proved by conducting more high-quality, multi-center and large-scale clinical trials. MMF alone has the same effect as the placebo dose, and it shows no differences in elevated serum creatinine after the treatment compared with conventional therapies.
Objective To assess the efficacy and safety of okra capsule for IgA nephropathy. Methods All randomized or quasi-randomized controlled trials (RCTs or quasi-RCTs) of okra capsule for IgA nephropathy were collected from CENTRAL, MEDLINE, EMbase, PubMed, WanFang Data, CNKI and CBM. Two reviewers independently screened the included studies, extracted the data, assessed the quality, and cross-checked then. Then RevMan 5.07 software was used for meta-analysis. Results Five RCTs were included. The results of meta-analyses showed that: compared with the control group, okra capsule was more effective in decreasing urinary protein (P≥0.05), but had no significant difference in improving renal function, reducing urine red blood cells and blood lipid (Plt;0.05). No research reported the adverse effects of okra capsule. Conclusion Current evidence reveals that okra capsule can reduce urinary protein and improving therapeutic effect for IgA nephropathy. However, further studies are needed to test its safety. Because of the small sample size and low methodological quality of the included studies, these results require more high-quality RCTs for further verification.
ObjectiveTo systematically review the efficacy and safety of tripterygium wilfordii Hook F (TwHF) in treatment of IgA nephropathy. MethodsThe Cochrane Library (Issue 4, 2014), PubMed, EMbase, CBM, CNKI, VIP and WanFang Data were searched up to April 28th, 2004 to collect randomized controlled trials (RCTs) about the efficacy and safety of TwHF in treatment of IgA nephropathy. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality of included studies. Metaanalysis was then conducted using RevMan 5.2 software. ResultsA total of 10 RCTs involving 521 patients were finally included. The results of meta-analysis showed that:a) compared with MMF group, TwHF group had better outcomes in complete remission (CR) (OR=2.01, 95%CI 1.04 to 3.87, P=0.04), total remission (TR) (OR=3.17, 95%CI 1.22 to 8.23, P=0.02), 24-hour urinary protein content (MD=2.61, 95%CI 1.34 to 3.88, P<0.000 1), and level of serum albumin (MD=-6.42, 95%CI -9.13 to -3.71, P<0.000 01); and b) compared with ACEI (ARB) group, TwHF group had better outcomes in complete remission (CR) (OR=4.25, 95%CI 2.63 to 6.86, P<0.000 01), total remission (TR) (OR=4.15, 95%CI 2.33 to 7.40, P<0.000 01), 24-hour urinary protein content (MD=1.15, 95%CI 0.63 to 1.66, P<0.000 1), and level of serum albumin (MD=-5.18, 95%CI -8.96 to -1.41, P=0.007), all with significant differences. ConclusionTwHF has favourable therapeutic efficacy and safety in treatment of IgA nephropathy. Due to limited quantity and quality of the included studies, the above conclusion should be verified by further conducting more high quality, large-scale, multicentre RCTs.
