[Activation of the interferon system enzymes by recombinant alpha2-interferon in patients with chronic hepatitis B].

Treatment of patients suffering from chronic hepatitis B with recombinant leukocytic interferon (reaferon) increased the levels of circulating interferon and activated interferon-dependent enzymes such as 2-5A-synthetase and histone kinase. Activation of the enzymes was observed for 1 to 2 weeks. After that period it was maintained at the required levels with intramuscular administration of 1-3 million units of reaferon 2 or 3 times a week. In parallel with increasing of the levels of the interferon system enzymes there was observed a decrease in the level of aminotransferase. The reaction of the viral antigens to the treatment with reaferon was not the same: HBe antigen and antibodies to HBe antigen disappeared, the content of HBs antigen and antibodies to delta-interferon did not change.
