Acetylcysteine therapy for chronic hepatitis C: are its effects synergistic with interferon alpha? A pilot study.

This trial reports the 6-month results of a pilot study using lymphoblastoid interferon alpha (IFNalpha) and acetylcysteine (N-acetylcysteine) separately and in combination in patients with chronic hepatitis C, genotype 1b, who were nonresponders to previous treatment with recombinant IFNalpha alone.21 patients were randomly divided into three groups of seven each. Group A was treated with lymphoblastoid IFNalpha 6MU three times a week for 6 months; group B received the same schedule of lymphoblastoid IFNalpha as group A plus acetylcysteine 1200 mg/day per os in two administrations, and group C received only acetylcysteine 1200 mg/day per os in two administrations.Mean serum alanine aminotr…
