ABSTRACT
BACKGROUND:
Risk factors for graft loss and recipient death in liver transplantation for hepatitis C virus (HCV) have been extensively investigated. Donor age was defined as one of the most important predictors of outcome in these patients; however, the mechanism leading to more severe recurrent hepatitis has not yet been investigated.METHOD:
In a retrospective analysis, histological findings of 79 donor liver grafts were assessed according to criteria inflammation, fibrosis, fatty degeneration, and necrosis. These findings were correlated with the histological and clinical course of HCV-positive liver graft recipients.RESULTS:
The overall 1-, 5- and 10-year graft survival figures were 85%, 77%, and 60%, respectively. We could not identify any correlation between outcome, fat content, and necrosis in the donor liver. However, stage 3 and 4 fibrosis 1 year after liver transplantation was significantly increased in the group of patients receiving a graft from a donor with portal inflammation (P<0.05). Additionally, the occurrence of intrahepatic inflammation was significantly increased in older donors (P<0.05) and donors with prolonged intensive care hospitalization (P<0.05).CONCLUSION:
A number of risk factors for detrimental outcome in HCV-positive patients after liver transplantation have been identified. In particular, older donor age significantly impaired outcome in recent analysis, but due to donor shortage it is not possible to provide young grafts for all HCV-positive patients. Our data show that donor histology is helpful in identifying patients with more severe recurrent hepatitis prior to transplantation, and that especially in older donors, prolonged intensive care hospitalization should be avoided.
