Effect of human fibroblast interferon (INF-beta) on hepatitis B virus DNA in serum.
Hepatitis B virus (HBV) DNA was measured by a hybridization technique in the sera of three patients with HBsAg-positive chronic active hepatitis treated with fibroblast interferon (INF-beta). Although DNA polymerase activity was undetectable in all patients 2-4 weeks after the beginning of the treatment, HBV-DNA was always present in two patients and disappeared in the only patient who showed marked clinical and histopathological improvement of the liver disease after INF treatment. This suggests that serum HBV-DNA is a valuable marker to monitor during therapeutic trials of chronic HBV infection.
