ABSTRACT
BACKGROUND/AIMS:
A combination of interferon alpha and ribavirin has been suggested to reach a higher rate of sustained virological response in patients with chronic hepatitis C than monotherapy. In this study we assessed the long-term efficacy of this combination therapy in the treatment of selected Italian naive chronic hepatitis C patients compared to interferon alpha monotherapy.METHODS:
We enrolled 428 naive patients who were randomly assigned to receive either recombinant interferon alpha-2b and ribavirin for 24 weeks or interferon alpha-2b alone for 48 weeks. The primary end-point of the study was the rate of sustained virological response. Serum HCV RNA levels were determined before treatment; during treatment at weeks 12 and 24 in the patients receiving the combination therapy; at weeks 12, 24, 36 and 48 in the patients receiving monotherapy; and after therapy at weeks 12, 24 and 48 in the patients in both study groups.RESULTS:
Sustained virological response was observed in 43% of the patients treated with combination therapy and in 14% of the patients treated with monotherapy. Logistic regression analysis showed that sustained response was associated with the combination therapy, with HCV genotype other than 1b, with an HCV viral load of 3x10(6) copies/ml or less, with an inflammation score of 7 or less, and with an estimated duration of disease of 10 years or less.CONCLUSIONS:
A 24-week treatment course with interferon alpha-2b and ribavirin offers a greater chance of sustained virological response compared to treatment with interferon alpha-2b alone for 48 weeks, and may be indicated as initial therapy in such patients.
