Hepatitis B virus DNA in chronic HBsAg carriers: correlation with HBeAg/anti-HBe status, anti-HD and liver histology.
Hepatitis B virus DNA was determined in the sera of 198 chronic hepatitis B surface antigen (HBsAg) carriers by the spot hybridization technique. The results were correlated with hepatitis Be antigen (HBeAg) and antibody (anti-HBe), delta antibody (anti-HD) and liver histology. All subjects had a liver biopsy. The prevalence of HBV DNA was 63% in HBeAg-positive subjects and 8.8% in anti-HBe positives. HBV DNA was not found more frequently in chronic HBsAg carriers who had histological evidence of liver disease than in carriers without such evidence. Anti-HD was detected in 48.5% of subjects, with an increasing trend (p less than 0.001) according to the severity of liver disease. Among patients with more severe liver disease (CAH and cirrhosis), HBV DNA and HBeAg were detected less frequently in anti-HD-positive than in anti-HD-negative subjects (7% vs. 42.3%, p less than 0.001 and 7% vs. 34.4%, p less than 0.005, respectively). These findings indicate that HDV infection jointly affects both HBeAg status and HBV DNA.
