Early and extended therapy for recurrent hepatitis C after liver transplantation.

ABSTRACT

BACKGROUND: End-stage cirrhosis due to hepatitis C virus (HCV) is one of the most common indications for orthotopic liver transplantation (OLT). Recurrence is universal and more aggressive than before OLT. The aim of this study was to evaluate the efficacy and tolerability of antiviral therapy in recurrent HCV after OLT. Therapy was started even with mild fibrosis (F < 2) and extended until 72 weeks, if it was possible. METHODS: Between November 2001 and December 2010, 279 OLTs were performed in 262 patients in our hospital; 81 (31%) for HCV-related cirrhosis. Nineteen patients were excluded because they died in the first 6 months. We treated 28 of 62 HVC patients. RESULTS: Twenty-eight patients met the indication for antiviral therapy 21 male (75%) and 7 female (25%), with a mean age of 56 years (range, 40 to 68 years). All the patients had histologically proven recurrence liver disease F1, 19 patients (68%); F2, 4 patients (14%), and F3, 45 patients (18%). The mean time to recurrence was 23 months, with a range of 3 to 90 months. Adverse effects (leukopenia in 82% and anemia in 79%) were treated with granulocyte colony-stimulating factor (GCSF) and erythropoietin (EPO), and dose reduction. Four patients (14%) were withdrawn from the treatment because of adverse effects. Nineteen patients achieved early virologic response (68%), and the sustained virologic response was 54% (15 of 28 patients). Five patients died (18%). CONCLUSION: Improving sustained virologic response in HCV liver transplant patients is a key goal. Antiviral therapy is safe and effective treating HCV recurrence after OLT. Starting this therapy in an early stage of hepatitis C recurrence, extending antiviral therapy (72 weeks), and avoiding dose reduction of antiviral drugs could help to achieve higher rates of sustained virological response.
