The efficacy of anti-viral therapy on hepatitis B virus-associated glomerulonephritis: A systematic review and meta-analysis
Abstract
Objectives. To assess the efficacy of anti-viral therapy on hepatitis B virus associated glomerulonephritis (HBV-GN).Design, setting, participants, & measurements. We searched PubMed, Embase and Cochrane Library for prospective controlled trials which assessed the efficacy of anti-viral therapy on HBV-GN in adult or pediatric patients between January, 1970 and October, 2010.Results were summarized using fixed-effects model because of an absence of heterogeneity among the studies (I2 = 0%). Results. Six trials with a total of 159 patients were included; among them five trials were specified as hepatitis B virus-associated membranous glomerulonephritis (HBV-MN). In adult patients, the incidence of proteinuria remission, not only total remission (complete remission CR + partial remission PR) (2.97 to 109.93, P = 0.002) but also CR (1.18 to 16.11, P = 0.03), significantly increased in the anti-viral treatment. In pediatric patients, only the incidence of total remission (1.77 to 17.75, P = 0.003) was increased significantly; the incidence of CR was not pooled with clinical and statistical heterogeneity (I2 = 81.5%, P = 0.004).Combine the data from adult and pediatric patients with HBV-MN, the same results were found. All the results of proteinuria remission kept with virologic response (VR), including HBeAg conversion (5.68 to 40.04, P < 0.00001) and reduction of HBV-DNA (5.60 to 463.16, P = 0.0005).Conclusions. Antiviral therapy including IFN and lamivudine is effective on remission of proteinuria, HBeAg clearance, and HBV-DNA reduction.
