Reinforced regimen of interferon alfa-2a reduces the incidence of cirrhosis in patients with chronic hepatitis C: a multicentre randomised trial. Multicentre GER-CYT-04 Group
Our aim was to assess and compare the long-term effect of interferon at standard (6 months) and reinforced dose and duration regimens in chronic hepatitis C.A multicentre institutional trial included 244 previously untreated patients with chronic hepatitis C, without cirrhosis, who were randomly allocated to either standard (3 MU thrice a week for 24 weeks; n=120) or reinforced (6 MU daily for 12 days, 6 MU thrice a week for 22 weeks, 3 MU thrice a week for 24 weeks; n=124) regimens. The main endpoint was sustained ALT response at 72 weeks (18 months); secondary end-points were virological (branched DNA and PCR) and histological responses (incidence of cirrhosis) at month 18.Sustained ALT response was observed in five patients (4%, 95% confidence interval 0-8%) in the standard group and in 21 patients (18%, 95% confidence interval 11-25%), from the reinforced group (p=0.002), in agreement with virological response in 21 (81%) patients. Cirrhosis at month 18 was observed in ten (10%) patients in the standard group and one (1%) in the reinforced group (p=0.004).The standard regimen of interferon, in chronic hepatitis C, confers a minimal sustained response rate at 18 months and may not prevent the occurrence of cirrhosis. Reinforced regimens allow sustained response to be reached in a limited number of patients and reduce the risk of cirrhosis during 18 months of follow-up.
