Donor age as a predictor of risk for short-term outcomes after liver transplant.

OBJECTIVES: To investigate an association between short-term mortality and donor age-associated worst outcomes in liver transplant. MATERIALS AND METHODS: A total of 178 consecutive patients underwent a liver transplant between 1999 and 2007. Among these patients, there were 172 liver transplants (donor age, 32.04 +/- 16.66; range, 2-65 years) and 167 recipients. Mean recipient age was 39.16 +/- 21.61 years (range, 6 months to 71 years), and 90 were males (53.8%). RESULTS: Among 172 transplants, 32.9% recipients died during follow-up (mean, 34.37 +/- 20.50 months). A lower mean recipient and graft survival occurred in donors older than 50 years (P = .01) and 30 years (P = .02) at 7-year patient survival. At 6- month and 1-year recipient survival, cutoffs were 50 and 55 years (P < .05). Log-rank test showed no statistical difference among recipients, and graft survival from donors older/younger 50 and 30 years 1.5 years after liver transplant (P < .565 and P < .259). CONCLUSIONS: Donor age is a key factor in liver transplant that carries prognostic impact in the recipients. Our data suggest that its harmful effects are exclusively elicited during the short-term, postoperative phase. We recommend careful and distinct management of recipients receiving grafts from elderly donors up to 1.5 years after liver transplant. Changes in the current early postoperative management of this selected group are encouraged.

Effects of donor age on patient survival in liver transplantation: short-and long-term analysis.

BACKGROUND/AIMS: This study aim was to investigate an association between donor age and lower recipient survival in liver transplantation. METHODOLOGY: A total of 178 consecutive patients underwent liver transplantation between 1999 and 2007. Among these patients, 172 liver transplants (donor age: 32.04 +/- 16.66) and 167 recipients were included in the analysis. Mean recipient age was 39.16 +/- 21.61 years (range: 6 mo-71 years) and 90 (53.89%) were males. RESULTS: Among 172 transplants, 32.9% recipients died during follow-up. Mean follow-up time was 34.37 +/- 20.50 mo. A lower mean recipient survival prevailed from donors older than 50 years (p = .01) at 7-year patient survival. At 6-month and 1-year recipient survival, cut-offs were 50 and 55 years, respectively (p < .05). A significant difference was observed in graft survival from donors older than 30 years (p = .02) and at 6-month and 1-year, cutoffs were 35 and 50 years, respectively (p < .05). CONCLUSIONS: Although the utilization of donors with increased age in liver transplantation offers a new option to increase the number of liver transplants it presents lower survivals. Other factors related to graft loss such as MELD score > 15 and longer CIT (cold ischemia time) should be avoided to reduce the risk of using elderly donor grafts.
