Therapy for chronic hepatitis C.
OBJECTIVE
in Hungary, over the past 5 years more than 900 patients with chronic hepatitis C have been examined for treatment with interferon at 16 major hepatology centres, using unified diagnostic and therapeutical criteria. Authors give an account of their experiences on the clinical features of patients with chronic hepatitis C and report the results of the interferon therapy.


METHODS
a total of 993 patients--virtually the entire Hungarian hepatitis C patient population who had been referred for interferon treatment--were included in the program. Actually, the sustained efficacy of the therapy was evaluated in 724 cases. Treatment protocols (dose of interferon and duration of therapy) have changed with time from a weekly dose of 3x3 MU IFN for 6 months in the first period, to 3x3-5 MU for 12 months in the second period, and finally in the third period a combination therapy with ribavirin has also been introduced.


RESULTS
in the first period, the end-of-treatment response (ETR) was 35%, sustained response (SR) 13%, the second phase schedule resulted in 42% ETR and 22% SR, while in the third period, ETR was 49% and SR 36%, respectively. Fibrosis in histology and baseline pretreatment HCV-RNA level appeared as predictors of response. The duration of treatment and the total dose of interferon exerted a moderate effect on therapeutic efficacy. Neither age nor gender influenced the outcome.


CONCLUSIONS
our results-obtained in a Central East European country-are in accordance with findings of suboptimal efficacy of traditional interferon monotherapy for chronic hepatitis C reported in the West, and suggest the benefit of the combination treatment of interferon with ribavirin.
