title: [A seroepidemiological study of hepatitis viruses among the patients with different types of liver disease in Qinhuangdao].
abstract: This article described a seroepidemiological surveillance in 326 patients with different clinical types of liver disease (acute hepatitis, AH; chronic hepatitis, CH; liver cirrhosis, LC; hepatocellular carcinoma, HCC) from hospitals in Qinhuangdao city during 1992-1995. The results showed that HAV infection could not develop chronic hepatitis. Among 238 patients of CH, LC, and HCC, anti-HAV IgM was not detected. HBV infection was the main pathogenic factor of CH, LC, and HCC with an infection rates of 77.78%, 84.21%, and 94.29%, respectively, the average rate of infection was 3.8 times higher than that in AH. HCV infection rate was increased gradually with development of chronic liver syndrome. Anti-HCV positive rate was 5.56% in CH, but 14.74% and 20.00% in LC and HCC respectively. HEV infection was found in patients with all types of liver disease with an average positive rate of 13.19%. It was not found that single HEV infection developed in CH, LC, and HCC. The average rate of super infection was 17.18% among all the patients, but the super infection rate in LC and HCC was 1.93 times higher than that in AH and CH. It seems that the super infection of HBV and HCV was the main factor for worsened liver symptoms and for developing LC and HCC.
