Biologic Significance of Hepatocyte Hepatitis B Core Antigen Expression in Chronic Hepatitis B Virus Infection

Abstract

To elucidate the biologic significause of hepatocyte B core antigen (HBcAg) expression and its relation to the natural course of hepatitis B virus (HBV) infection, we tried to correlate the patterns of HBcAg with the HBV replication state and with disease activity in 40 needle biopsies performed on hepatitis B surface antigen (HBsAg) carriers aged from 15 to 46 years. In 32 of 40 cases, HBcAg was present in the hepatocyte nucleus (nHBcAg), in the cytoplams (cHBcAg) or in both (mixed). Pure nHBcAg was seen only in minimal hepatitis, but a diffuse pattern of expression of cytoplasmic HBcAg and mixed cytoplasmic and nuclear expression of HBcAg were seen in active hepatitis. There was also a good correlation between liver HBcAg and serum HBeAg. Cases in which HBcAg expression were observed were positive for serum HBeAg (81%) and the cases negative for HBcAg were all positive for serum anti-HBe.
