The therapy of glomerulonephritis is guided by a limited number of individual clinical trials and treatment recommendations are based on meta-analysis and Cochrane Systematic Reviews. The impact of such therapy standards on the prognosis of glomerulonephritis is not known. Methods: Between October 2002 and December 2008 patients with abnormal urine findings and/or decreasing renal function of unknown cause were referred for renal biopsy. In a collaboration of out-patient nephrologists with a major teaching hospital, all patients received treatment recommendations according to evidence-based therapy guidelines based on Cochrane Systematic Reviews. Patient charts were systematically reviewed and patients were re-examined for follow-up until November 2009. Cox Regression analysis was performed to identify independent prognostic factors. Results: Two hundred patients with primary or secondary glomerulonephritis were identified. Complete follow-up data were available from 196 patients with 324 therapeutic interventions. The mean follow-up was 2.8 ± 2.0 years. Among all patients, 37% remained unchanged ill, 13% died, 17% had progressing renal disease, while 19% had a complete and 14% a partial remission. Proteinuria declined in primary glomerulonephritis (5.0 ± 5.4 g/d to 2.1 ± 3.4 g/d, p Conclusions: In a multivariate model of standardised glomerulonephritis therapy the presence of tubulointerstitial fibrosis was associated with death or progresssive renal disease, while prednisolone-based therapy regimens and intensified nephrological follow-up resulted in a significant delay of endstage-renal failure. This result should direct future health care policies because glomerulonephritis accounts for nearly 20% of the dialysis population.展开更多

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

The long-term renal survival has improved dramatically since the addition of cyclophosphamide(CYC) and recently of rituximab(RTX) in association with corticosteroids in the remission induction thera-peutic regimens. However, renal prognosis remains unfavorable for many patients and the mortality rate is still significantly high. In this review, we analyze the open challenges to be addressed to optimize the induction remission therapy, principally in patients with advanced kidney failure. This concern the first-line therapy(CYC or RTX) based on different parameters(estimated glomerular filtration rate at baseline, new or relapsed disease, ANCA specificity, tissue injury, safety), the role of plasma exchange and the role of new therapies. Indeed, we discuss future perspectives in induction remission therapy by reporting recent advances in new targeted therapies with particular reference to avacopan, an orally administered selective C5a receptor inhibitor.展开更多
