Abstract

The outcomes and characterization of hepatitis C virus (HCV) infections after pediatric liver transplantation (LT) have rarely been reported. We describe our experience with HCV infections after pediatric LT. Ten of 207 children (4.8%) who underwent LT at our institution (1985-2010) developed previously undiagnosed HCV disease. Eight received a liver graft before blood product and donor screening for HCV became available. The mean age at transplantation was 8.9 ± 4.3 years, and the median time from transplantation to the diagnosis of HCV was 15.1 years (range = 0.2-19.7 years). The genotypes were 1 (n = 8), 3 (n = 1), and undetermined (n = 1). At the time of this writing, all the patients were still alive with a mean follow-up of 7.3 ± 5.5 years after the diagnosis of HCV. Five patients did not receive treatment; 2 of these patients achieved spontaneous viral clearance (SVC). Four of the 5 treated patients achieved a sustained virological response, and 3 had an early virological response (EVR). Two of these 4 patients developed chronic rejection while they were on treatment, but this was resolved with a conversion from cyclosporine A to tacrolimus. The remaining patient was continuing treatment and had achieved EVR. In conclusion, despite the limitations of our series, de novo HCV infections after pediatric LT seem to have a slow histological progression. Even with genotype 1, the patients have a good long-term prognosis and respond well to treatment. Nevertheless, chronic rejection during antiviral therapy may develop. In addition, SVC may occur in this population. Copyright © 2011 American Association for the Study of Liver Diseases.
