RESUMO
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 (I(2) = 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 (I(2) = 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.

Between December 1984 and November 1996, 171 children under 12 years old presented to the University Hospital of the West Indies with nephrotic syndrome. Hepatitis B surface antigen (HBsAg) was found in ten (6%) of these children, eight of whom had membranous nephropathy (MN), and one each had mesangial proliferative glomerulonephritis (MesN) and minimal change nephrotic syndrome (MCNS). Only those children with MesN and MCNS were steroid-sensitive. The HBsAg-positive status was identified incidentally on screening. At a mean follow-up of 34 months, seven of ten children had experienced complete or partial remission and three had persistent nephrotic syndrome, although none was in renal failure. Six of the ten had biochemical hepatitis. All the children were still HBsAg-positive. Hepatitis B virus (HBV) is a factor contributory to nephrotic syndrome in Jamaican children. As diagnostic clinical markers for HBV-associated nephropathy are usually absent, all children presenting with nephrotic syndrome should be screened for HBsAg. A policy should be implemented in Jamaica for screening pregnant women and at-risk groups for HBsAg, as well as for immunising susceptible neonates, in order to reduce the incidence of HBV-associated pathology.
