BackgroundTo investigate the effect of HBV markers on HBV-GN.MethodsThe immunohistochemistry was used to detect HBsAg and HBcAg in frozen sections of renal biopsy, the changes in HBV serum markers, renal functional parameters and clinical manifestations or symptoms were observed to analyze renal damage.ResultsUsing renal biopsy data from 329 cases, this study found that the most common pathological subtype in HBV-GN was mesangioproliferative glomerulonephritis (MsPGN) (24.9%, P <0.05), and 29.4% of patients who show serological HBsAg, HBeAg and anti-HBc positive developed membranoproliferative glomerulonephritis (MPGN) (P <0.05). The immunohistochemistry was used to detect HBsAg and HBcAg in frozen sections.50% of HBsAg and HBcAg deposits was observed in the glomeruli of MPGN patients, while 36.6% of HBsAg and 43.9% of HBcAg deposited in the glomeruli of MsPGN patients. The deposits of HBsAg and HBcAg in glomeruli were directly correlated with IgA, IgG, IgM and C3 deposits. In addition, cases with a moderate to severe decrease as reflected by the glomerular filtration rate (GFR) were predominantly patients with MPGN (31.6%, P <0.05) or MsPGN (21.1%, P <0.05). Patients who were serological HBsAg, HBeAg and anti-HBc positive or HBsAg, anti-HBe and anti-HBc positive mainly exhibited urine and renal parameter changes.ConclusionExamination of HBV markers in serum and renal biopsy will be useful for clinicians to predict the renal damage in early stage when it is reversible in HBV-GN.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
