A case of acute exacerbation of chronic hepatitis B accompanied by antibody to HBeAg with remission of liver damage after long-term treatment with interferon.
The patient was a 47-year-old female with chronic hepatitis B having antibody to HBe antigen (HBeAg). She was admitted to our hospital in March, 1994, because of acute exacerbation of chronic hepatitis B. Laboratory data revealed the elevated serum transaminase and DNA-polymerase levels, and decreased prothrombin activity. The histological examination of the liver showed chronic active hepatitis with severe hepatic necrosis. Point mutation of the precore region of HBV-DNA (pre-C mutant) was observed in clones from this case by polymerase chain reaction method. The patient was treated with recombinant interferon alpha-2a 9 MU daily for 2 weeks and thereafter 3 times weekly for 6 months. After interferon therapy, the pre-C mutant disappeared with the improvement of transaminase levels and prothrombin activity. These findings suggest the possibility that long-term treatment with interferon therapy is effective for the acute exacerbation of chronic hepatitis B accompanied by antibody to HBeAg.
