Résumé
Background & Aims: We aimed at determining the effect of maintenance therapy with ribavirin alone, after a year of combined peginterferon-alfa 2a (PegIFN alpha-2a) and ribavirin therapy, on viral response and liver histology after liver transplantation (LT).
Methods: Hundred and one patients with recurrent HCV and a minimum of stage 1 fibrosis (METAVIR scoring), 1-5 years after LT, were enrolled. PegIFN alpha-2a and ribavirin were initiated at 90 mu g/wk and 600 mg/d, respectively, then increased or adjusted as a function of tolerance. At 12 months, combination therapy was discontinued and patients were randomized to ribavirin or placebo for a further 12 months. Growth factor use was permitted.
Results: At 18 months, a sustained virological response (SVR) was obtained in 47.9% of patients in Per Protocol (PP) analysis, and was higher in patients with genotype 2 or 3 than in patients with genotype 1 or 4, in patients with genotypes 1 + 4 receiving ciclosporine than in those receiving tacrolimus, in patients with worse renal function, in those having received EPO, in patients with lower weight, and in those with lower viral load at 3 months. Using logistic regression, only the early viral response, recipient weight and renal function were independently associated with better SVR. SVR, viral load, activity, and fibrosis scores were similar, at M18 and M30, in patients randomized to ribavirin, or to placebo.
Conclusions: A PP SVR was achieved in 47.9% of patients with established recurrent hepatitis C after LT. Maintenance therapy with ribavirin alone does not improve the virological response or the histological parameters. (C) 2012 European Association for the Study of the Liver. Published by Elsevier B.
