title: PCR analysis of hepatitis B virus DNA in paraffin-embedded liver tissue from patients with chronic liver disease.
abstract: We described a nested polymerase chain reaction protocol to detect hepatitis B viral DNA in paraffin-embedded liver tissue and tried to determine whether this virus was associated with non-B chronic liver disease. Fifty-five samples were obtained from 28 patients with B, and 27 patients with non-B chronic liver disease (35 cirrhosis, 4 hepatocellular carcinoma and 16 chronic hepatitis). The two sets of primers amplify a sequence located in a conserved polymerase/surface region of the viral genome. Reaction products were analysed using a nonisotopic hybridization method. None of the 27 (0%) seronegative samples and 20 of the 28 (71%) seropositive specimens were positive for hepatitis B virus DNA. There were 4 false negatives in which beta-globin PCR was positive. Although its sensitivity is reduced in formalin-fixed paraffin-embedded tissue, nested PCR allows rapid detection of HBV DNA sequences and can be a useful tool if no frozen tissue is available.
