Management of chronic active B hepatitis with alpha interferon.

Patients with chronic active B hepatitis entered into an open study of IFN maintenance therapy. They received 3 x 10(6) I.U. INTRON-A by subcutaneous injection three times a week for a 4-month period. Four patients out of ten became HBeAg negative and anti-HBe, which was accompanied by the return of serum liver function tests to normal. In a control group with eleven patients, given only vitamins, no changes were registered in serological and biochemical data. Fever, "flu-like illness", fatigue were the main side-effects observed during the course of IFN therapy, which had not to be discontinued.
