Pilot study of a short course of ribavirin and alpha interferon in the treatment of chronic active hepatitis C not responding to alpha-interferon alone.
Chronic active hepatitis due to HCV represents a severe progressive disorder of the liver, At present, Interferon seems to be the most efficacious treatment available, however, only 20-25% of the patients treated achieve complete remission. The efficacy has, therefore, been evaluated of Ribavirin, a nucleoside analogue active both on DNA and RNA viruses, in the treatment of non responders to a previous course of interferon. Twenty patients were randomly assigned to two groups: A) received the association R (800 mg/day for 2 months)+interferon (9 Mu/week for 6 months); B) received IFN (9 Mu/week for 6 months). All patients completed the study without important side effects. Four patients in group A presented reduced ALT and loss of viraemia during treatment with Ribavirin. Only one patient in group B had reduced indices of cell lysis and was negative for HCV-RNA during the course of the study. However, viremia and an increase of ALT values were observed in all of these subjects once treatment was interrupted. The results emerging from this study indicate that Ribavirin therapy, at the dose and duration of treatment employed, is not sufficient to change the natural course of events of chronic active hepatitis from HCV.
