title: Hepatitis B core and surface antigens and delta agent in chronic liver disease in Kuwait.
abstract: Hepatitis B surface antigen was detected immunohistochemically in 25 out of 85 liver biopsies (29.4%) of chronic liver disease. Core antigen was also demonstrated in 9 of the 25 Hepatitis HBs Ag positive biopsies (36%). Delta agent however, was found in only one case of HBs positive chronic active hepatitis. The number of hepatocytes staining positively for HBc antigen was greater in those biopsies with the strongest staining for HBs antigen. The only case of chronic active hepatitis positive for delta agent showed that the positive staining was confined to the nuclei of few hepatocytes. The routine histology showed chronic active hepatitis with a moderate degree of inflammation. The present results confirm our previous reports that almost one third of chronic liver disease in Kuwait is associated with hepatitis B infection. Previous serological studies suggest that delta agent infection is also common; however, the present study suggest that delta agent may be a transient, and not a major, contributing factor in the progression of liver disease.
