Systematic review of the treatment of established recurrent hepatitis C with pegylated interferon in combination with ribavirin.
The aim of our study was to conduct a systematic review of studies evaluating antiviral therapy with pegylated interferon (PEG-IFN) alfa in combination with ribavirin for the management of recurrent hepatitis C after liver transplantation. Data sources included electronic databases and a manual search. Studies evaluating the efficacy and tolerability of PEG-IFN alfa with ribavirin in patients with recurrent hepatitis C were selected for inclusion. The information extracted from each of the selected publications included study design details, patient characteristics, treatment regimens and efficacy and tolerability end points. Nineteen studies including 611 patients were identified. PEG-IFN alfa-2b was used in 16 studies. The mean rate of SVR was 30.2% (range, 8-50%). Dose reduction and discontinuation of treatment were common in these studies (73% and 27.6%, respectively). The lack of an early virologic response (EVR) at 3 months of therapy was the most frequently described predictive factor of nonresponse. Treatment discontinuation and dose reductions due to adverse events were frequent and possibly represent important obstacles to attainment of SVR. EVR at 3 months of treatment should be considered an important predictor of treatment outcome.
