Advanced donor age increases the risk of severe recurrent hepatitis C after liver transplantation

The association between donor age and the severity of recurrent hepatitis C and, whether there is any donor age above which severity of recurrence increases significantly, were analyzed. A total of 131 liver grafts of hepatitis C virus (HCV)-infected recipients were selected for the study. Distribution of donor age was compared between grafts with and without severe recurrence. The risk of developing severe recurrence as well as the hepatitis-free, severe hepatitis-free and HCV-related graft survival was compared between different donor age groups. Mean donor age was higher for grafts with severe recurrence (P = 0.007). The risk of developing severe recurrence within 2 years post-transplant increased with donors aged >= 50 years (RR = 1.34) and donors aged >= 70 years (RR = 1.61). Five-year severe hepatitis-free survival rates decreased progressively when donor age was over 50 years (P < 0.001). The study shows 50 and 70 years as the donor age cut-off points above which the evolution of HCV-infected recipients worsens.
