Serologic studies of hepatitis viruses for their aetiologic role in chronic liver disease.

Abstract

Serum samples from 130 patients with chronic (persistent or active) hepatitis, including cirrhosis, and 70 patients with chronic alcoholic disease, all confirmed by biopsy, were examined by counter electrophoresis (CEP) for HBsAg. The patients were residents in the South-Transdanubian region of Hungary. Of the former 25%, of the latter 3%, proved positive. In 138 of the cases, 4 different tests were performed, viz. CEP, complement fixation, reverse passive haemagglutination (RPH) and radioimmunoassay (RIA). The results were positive in 24, 36, 43 and 60%, respectively, in chronic hepatitis and in 4, 6, 8 and 14%, respectively, in cases of alcoholic origin. Serum samples from the same patients were tested for anti-HBs and anti-HBc. Positive anti-HBs was found in 24% of the patients with chronic hepatitis and in 26% of those with alcoholic liver disease. The presence of anti-HBc was demonstrated in 42% and 38%, respectively. Joint evaluation of RPH-positive and anti-HBc positive cases on the one hand and of RIA-positive and anti-HBc positive cases on the other resulted in 68% and 71% HB virus-related positivity, respectively. The present study failed to furnish evidence in support of the presence of hepatitis A virus of its involvement in the aetiology of chronic liver disease.
