Management of telaprevir-based triple therapy for hepatitis C virus recurrence post liver transplant

摘要

AIM: To characterize management of telaprevir(TVR)-based triple therapy of hepatitis C virus(HCV) reinfection after liver transplantation(LT).METHODS: We retrospectively analyzed safety and efficacy of telaprevir- based triple therapy in a single center cohort of 19 patients with HCV genotype(GT) 1 recurrence after LT, with respect to factors possibly predicting sustained viral response(SVR) or non-SVR. All patients were treated with TVR, pegylated(PEG) and ribavirine(RBV) for 12 wk followed by a dual phase with PEG/RBV for 12 wk in 7 patients and for 36 wk in 5 patients. RESULTS: In total 11/19(58%) of patients achieved a sustained response. All(11/11) SVR patients showed a rapid viral response at treatment weeks 4 and 11/14 rapid virological response(RVR) patients achieved SVR. Notably, all(7/7) patients who completed 48 wk of therapy and 80%(4/5) patients who completed 24 wk of therapy achieved SVR24. Treatment failure was significantly(P > 0.049) more frequent in GT1 a infection(5/7) compared to GT1b(3/12) infection and was associated with emergence of resistance-associated mutations in the NS3 protease domain. Bilirubin level at baseline is also related to SVR(P > 0.030). None of the patients had to discontinue treatment due to side effects. CONCLUSION: RVR, GT and bilirubin are clearly related to achievement of SVR. Providing a thorough patient selection and monitoring, a full course of TVR-based triple therapy in LT patients is feasible and achieves high SVR rates.
