title: Preliminary report on seroepidemiology of HCV and HBV infection in northern China.
abstract: 1 141 serum samples from various population groups in north China were examined for C100-3Ab by ELISA. Antibody to C100-3 antigen derived from HCV genome (C100-3A) and HBsAg were measured in 438 normal population in Beijing. The C100-3Ab positive rate was 2.1% and the HBsAg positive rate was 2.5%. There is increased occurrence with age. In 649 cases of chronic liver diseases, the HBsAg positive rate was 87.1% in chronic persistent hepatitis (CPA), 88.8% in chronic active hepatitis (CAH), 64.9% in liver cirrhosis (LC) and 67.3% in hepatocellular carcinoma (HCC). The C100-3Ab positive rate was 10.5% (CPH), 12.1% (CAH), 42.6% (LC) and 38.4% (HCC). It is noteworthy that the C100-3Ab positive rate significantly increased with disease progression from CPH to CAH, LC and HCC. Prevalence of cases positive for both C100-3Ab and HBsAg was 0% in the normal population, 6.7% in CPH, 8.4% in CAH, 31.1% in LC and 28.8% in HCC. Investigation of patients with HCV infection showed that only 36.8% had blood transfusions. HCV and HBV infection may play important pathogenic roles in CPH, CAH, LC and HCC in north China.
