Résumé
OBJECTIVE: The natural history of mild chronic hepatitis C is not well-known and the benefit of treating this form of the disease is not well-defined. We conducted a pilot study to answer this question. DESIGN: Mild chronic hepatitis C was defined by positivity for anti-HCV antibodies, detectable serum HCV RNA by PCR, and a Knodell score < or = 5 on a liver biopsy performed within the previous 6 months. Eighty patients from six centres were randomized into two groups receiving interferon alpha-2b, 3 MU three times a week for 6 months (group 1, n = 39) or no treatment (group 2, n = 41). Sustained response was defined by the loss of detectable serum HCV RNA at 6 months after therapy. RESULTS: The two groups were not different at entry with respect to age, sex ratio, source of infection, disease duration, genotype, viral load and Knodell score. One patient (group 1) was excluded from the study, while two patients in group 1 (5%) and seven in group 2 (17.1 %) did not complete the trial. A sustained response was observed in seven patients (18%) in group 1 versus none in group 2 (P < 0.01). The difference in mean Knodell score remained non-statistically significant between the two groups at the end of the study. Reduction or interruption of interferon was necessary in eight patients (24.2%). CONCLUSIONS: This first randomized controlled study in mild chronic hepatitis C shows a proportion of sustained responders to interferon alpha-2b similar to that observed in active chronic hepatitis C.
