Consensus interferon versus interferon-alpha 2b plus ribavirin in patients with relapsing HCV infection.

Management of HCV infection and related liver disease with treatment currently available lead to a sustained virological response in 20% of patients using interferon (IFN)-alpha mono-therapy and approximately 40-45% in those on combination therapy with ribavirin.The aim of the present investigation was to compare the effect of consensus interferon alphacon-1 (C-IFN), and IFN-alpha 2b plus ribavirin, in patients relapsing after treatment with interferon alone. A total of 112 randomised patients with relapsing HCV infection (M/F=53/59), were treated for 24 weeks with: (A) IFN-alpha 2b starting with 5/6MU/day till negativity of HCV-RNA followed by 3MU every other day, plus ribavirin 15mg/kg/day (n=34); (B) C-IFN 9microg/day (n=40); (C) ursodeoxycholic acid (UDCA; sodium salt) 450mg/day (n=37).
