Sustained Clearance of Serum Hepatitis C Virus-RNA Independently Predicts Long-Term Survival in Liver Transplant Patients With Recurrent Hepatitis C

The aim of this study was to analyze the impact of virological response to long-term antiviral therapy using interferon plus ribavirin on survival of 30 liver transplant patients with recurrent hepatitis C. Mean treatment duration is currently 46 months (range: 3-144 months). Sustained clearance of serum hepatitis C virus RNA was achieved in 18 patients (60%). Allograft biopsies demonstrated fibrosis progression in seven virological nonresponders (66.6%), and none of the recipients with viral elimination (0%; P<0.001). Univariately, low pretransplant viral loads, the absence of cytomegalovirus infection, as well as biochemical and virological response to antiviral therapy indicated a positive impact on outcome (P<0.05). Only antiviral treatment induced clearance of viremia, however, was identified as independent predictor of long-term survival (P=0.02). Our data indicate that an antiviral combination should aim at viral eradication in liver transplant patients with recurrent hepatitis C, because it improves survival.
