Clinical evaluation of intramuscular administration of natural interferon-gamma in the treatment of chronic hepatitis B.
Natural interferon-gamma at a dose of 0.5 x 10(6) or 1 x 10(6) IU daily was intramuscularly administered daily for 4 weeks to 15 patients with chronic hepatitis B. The efficacy and safety of the treatment were evaluated for 24 weeks following the completion of the 4-week treatment period. Persistent disappearance of HBeAg was observed in 5 of 15 patients. Serum hepatitis B virus (HBV)-related DNA polymerase disappeared in 5 of 13 patients at the end of interferon therapy. On the other hand, serum ALT and beta 2-microglobulin levels showed a significant increase during the interferon therapy period. The side effects were completely reversible. These findings suggest that interferon-gamma has an antiviral effect in patients with chronic hepatitis B and that the main mechanism of the therapeutic effect may be associated with the elimination of HBV-infected hepatocytes due to the immunopotentiating effect of the substance.
