BACKGROUND & AIMS: Several studies have shown that new direct-acting antivirals maintain their efficacy in liver transplant (LT) recipients with severe hepatitis C virus (HCV) recurrence. We determined the clinical impact of sofosbuvir/ribavirin in LT through the changes in liver function and fibrosis state at 24 and 48 weeks after treatment. METHODS: Between June 2014 and July 2015, 126 patients (30 F3, 96 F4 Metavir stage) were enrolled to receive sofosbuvir + ribavirin (24 weeks, 118 patients) or sofosbuvir + simeprevir + ribavirin (12 weeks, 8 patients); treatment was initiated at a median time of 4.3 years from LT. Median follow-up after therapy completion was 461 days. RESULTS: All 30 F3 patients achieved a sustained virological response at week 24 after treatment (SVR24) and showed a distinct amelioration of the AST-to-platelet ratio index (APRI), FIB-4 and liver stiffness at elastography by week 24 post-therapy, which were maintained at week 48. Of the 96 F4 cirrhotic patients, 72 (75%) achieved SVR24 accompanied by significant improvement of liver function, which was maintained at week 48 (Child B-C 22% baseline, 11% week 24, 7% week 48); APRI, FIB-4 and liver stiffness further improved significantly between weeks 24 and 48 of follow-up. Among the 77 responders (27 F3, 50 F4) who underwent elastography at baseline and at the end of follow-up, 39 (50.6%; 18 F3, 21 F4) exhibited a regression in fibrosis stage. CONCLUSION: At about 1 year from the completion of successful sofosbuvir-based therapy, patients with post-LT HCV and severe fibrosis experienced a long-term liver function improvement accompanied by a regression of fibrosis stage in half of them.

Abstract
BACKGROUND & AIMS: Several studies have shown that new direct-acting antivirals maintain their efficacy in liver transplant (LT) recipients with severe hepatitis C virus (HCV) recurrence. We determined the clinical impact of sofosbuvir/ribavirin in LT through the changes in liver function and fibrosis state at 24 and 48 weeks after treatment. METHODS: Between June 2014 and July 2015, 126 patients (30 F3, 96 F4 Metavir stage) were enrolled to receive sofosbuvir + ribavirin (24 weeks, 118 patients) or sofosbuvir + simeprevir + ribavirin (12 weeks, 8 patients); treatment was initiated at a median time of 4.3 years from LT.
