METHODS:Six and five trials were used respectively to evaluate the efficacy of either antiviral or corticosteroid treatment on HBV-GN.Pediatric patients were pooled separately to assess their response to the above treatment modalities.The primary and secondary outcomes were remission of proteinuria and clearance of Hepatitis B e-antigen(HBeAg) ,respectively.A fixed or random effect model was established to collect the data. RESULTS:The remission rate of proteinuria(RR=1.69,95%CI:1.08-2.65) and the clearance rate of HBeAg(RR =6.44,95%CI:3.11-13.35) were significantly higher in antiviral treatment group than in control group.The proteinuria remission was significantly associated with HBeAg clearance(P=0.002) .However,the difference in proteinuria remission rate was not statistically significant between corticosteroid treatment group and controlgroup(RR=1.45,95%CI:0.68-3.11) .Antiviral therapy could significantly promote the HBeAg clearance in pediatric patients,but neither antiviral nor corticosteroid therapy could significantly decrease proteinuria in pediatric patients compared to controls. CONCLUSION:Antiviral but not corticosteroid treatment can decrease proteinuria and promote HBeAg clearance in HBV-GN patients.展开更多

Methods 102 patients with HBV-GN were divided into 3 groups, according to the serum titer of the HBV DNA. 24-h urine protein excretion, and other parameters were measured. Renal biopsy were performed. The association between HBV DNA and the pathological stage of membranous nephropathy was analyzed in 78 patients with HBV-MN. 24-h urine protein excretion was used for the evaluation of the prognosis, and the relationship between HBV DNA and prognosis were analyzed. Results Several findings were demonstrated with the increase of serum HBV DNA： 24-h urine protein excretion, plasma cholesterol, and triglycerides increased significantly（P〈0.05）, while the plasma level of albumin decreased significantly（P〈0.05）; The changes of serum creatinine, C3 and C4 were found but no statistical significance. Glomerular deposition of HBVAg increased, and the pathological injury was more severe. The clinical remission rate was lower in the high replication group after treatment as compared with the low replication group（P〈0.01）. Conclusion With the increase of serum HBV DNA, the urine protein excretion and the kidney injury were more severe, and the clinical remission rate was decreased.展开更多
