Abstract
The diagnostic value of hybridization analyses for the detection of hepatitis B virus (HBV) DNA in serum and liver tissue was investigated in 79 patients with chronic liver disease. Active viral replication was demonstrated by the detection of HBeAg or HBV-DNA in serum or liver tissue. However, HBV-DNA was also detected in the absence of HBeAg in serum. No correlation was found between the presence of HBV-DNA in serum or liver tissue and clinico-chemical or histological disease. In HBsAg-negative patients no HBV-DNA was detected in serum or liver tissue. These data indicate that serological markers are sufficient for the diagnosis of HBV infection. However, detection of HBV-DNA in serum or active viral replication in liver tissue is important in selecting patients for antiviral therapy (e.g. interferon) and monitoring its efficacy.
