Abstract |
Background : Infection with hepatitis B virus has been a major health problem. Chronic viral hepatitis B is the
principal cause of chronic liver disease, cirrhosis, and hepatoma. A number of studies have showed that a course of
interferon (INF) treatment induces a long-term remission in 20~40% of patients. Compared with the use of lamivudine,
INF therapy is followed by delayed clearance of HBsAg and the treatment improves the natural history of chronic
hepatitis B. The aim of this study is to evaluate the efficacy of the use of different dosages of alpha-interferon treatment
in patients with chronic hepatitis B.
Methods : We conducted a one-and-a-half year, randomized clinical trial of interferon in 24 Korean chronic hepatitis
B patients with a positive HBeAg, and excluded other liver problems with biopsies. The patients were randomly assigned
to receive 5 million units (n=10) of interferon-α2b and 10 million units (n=14) of interferon-α2b three times weekly for
16/24 weeks. Patients were followed for 12 months after the cessation of the therapy, and the patients received a second
biopsy.
Results : After treatment with interferon, 29.2% of the patients became negative for HBeAg and the presence of HBV
DNA. Fifty percent of the patients showed histological improvement. The differences of the loss of HBeAg, HBV DNA
and histological improvement between the two groups were not significant. HBV DNA and ALT were not valuable as
predictive variables in treatment efficacy. However, the rate of histological improvement in patients with a low ALT level
was higher.
Conclusions : The administration of different doses of interferon-α2b during treatment in patients with chronic
hepatitis B did not show a significant difference in efficacy.(Korean J Med 73:464-473, 2007) |
