Protease inhibitors (PI) with peg-interferon/ribavirin have significantly improved SVR rates in HCV G1 patients. Their use to treat HCV recurrence after liver transplantation (LT) is a challenge.
This cohort study included 37 liver transplant recipients (male: 92%, age 57±11years), treated with boceprevir (n=18) or telaprevir (n=19). The indication for therapy was HCV recurrence (fibrosis stage > then or equal to F2 (n=31, 83%) or fibrosing cholestatic hepatitis (n=6, 16%).
Eighteen patients were treatment-naive, five were relapsers and 14 were non-responders to dual therapy after LT. Twenty-two patients received cyclosporine and 15 tacrolimus. After 12 weeks of PI therapy, a complete virological response was obtained in 89% of patients treated with boceprevir, and 58% with telaprevir (P=0.06). The end of treatment virological response rate was 72% (13/18) in the boceprevir group and 40% (4/10) in the telaprevir group (P=0.125). A sustained virological response 12 weeks after treatment discontinuation was observed in 20% (1/5) and 71% (5/7) of patients in the telaprevir and boceprevir groups, respectively (P=0.24). Treatment was discontinued in 16 patients (treatment failures (n=11), adverse events (n=5)). Infections occurred in ten patients (27%), with three fatal outcomes (8%). The most common adverse effect was anemia (n=34, 92%), treated with erythropoietin and/or a ribavirin dose reduction; thirteen patients (35%) received red blood cell transfusions. The cyclosporine dose was reduced by 1.8±1.1-fold and 3.4±1.0-fold with boceprevir and telaprevir, respectively. The tacrolimus dose was reduced by 5.2±1.5-fold with boceprevir and 23.8±18.2-fold with telaprevir.
Our results suggest that triple therapy is effective in LT recipients, particularly those experiencing a severe recurrence. The occurrence of anemia and drug-drug interactions, and the risk of infections, require close monitoring.
