Analysis on relevant factors for hepatitis B virus-associated glomerulonephritis / 中华肾脏病杂志

ABSTRACT

Objective To retrospectively evaluate the relevant factors for hepatitis B virus-associated glomerulonephritis (HBV-GN).Methods A total of 86 patients with pathologyproven HBV-GN and 135 HBV carriers with non-HBV-GN were included in this retrospective casecontrol study.Logistic regression analysis was used to detect the relevant factors for HBV-GN.Results On univariate analysis,the factors associated with HBV-GN were as follows: male (OR 2.79,95%CI 1.48-5.25,P=0.001),HBeAg positivity (OR 2.60,95%CI 1.49-4.53,P=0.001),HBV replication (OR 3.63,95%CI 1.80-7.33,P＜0.01),liver cirrhosis (OR 4.58,95%CI 1.41-14.91,P=0.011),and elevated alanine aminotransferase (ALT) (OR 2.53,95%CI 1.42-4.51,P=0.002).On multivariate analysis,the associations remained significant for male (OR 2.21,95%CI 1.12-4.33,P=0.022),HBV replication (OR 2.77,95%CI 1.28-5.97,P=0.01),liver cirrhosis (0R 4.55,95%CI 1.29-16.10,P=0.019) and elevated ALT (OR 1.96,95%CI 1.04-3.69,P=0.037).Compared with HBV-associated IgA nephritis (HBV-IgAN) in multivariate model,HBV-associated membranous nephropathy (HBV-MN) or membranoproliferative glomerulonephritis (HBV-MPGN) was significantly associated with male (OR 6.51,95%CI 1.76-24.11,P=0.005) and HBV replication (OR 7.22,95%CI 1.68-30.97,P=0.008).Conclusions Male,HBV replication,liver cirrhosis and elevated ALT may be predictive factors for HBV-GN.Compared with HBV-IgAN,HBV-MN or HBV-MPGN is significantly associated with male and HBV replication.
