Abstract
Survival following liver transplantation for hepatitis C virus (HCV) is significantly poorer than for liver transplants performed for other causes of chronic liver disease. The factors responsible for the inferior outcome in HCV+ recipients, and whether they differ from factors associated with survival in HCV- recipients, are unknown. The UNOS database was analyzed to identify factors associated with outcome in HCV+ and HCV- recipients. Kaplan-Meier graft and patient survival and Cox proportional hazards analysis were conducted on 13,026 liver transplants to identify the variables that were differentially associated with outcome survival in HCV- and HCV+ recipients. Of the 13,026 recipients, 7386 (56.7%) were HCV- and 5640 were HCV+. In HCV- and HCV+ recipient populations, five-year patient survival rates were 83.5% vs. 74.6% (PP A number of parameters are differentially correlated with outcome in HCV- and HCV+ recipients of orthotopic liver transplantion. These findings may not only have practical implications in the selection and management of liver transplant patients, but also may shed new insight into the biology of HCV infection posttransplant.
