Abstract
In this retrospective single-center study we evaluated the outcome after kidney transplant in recipients older than 65 years in terms of patient and graft survival and causes of death. Patients and MethodsFrom 1993 to 2016, 109 consecutive first single kidney transplants in recipients older than 65 years were included. Furthermore, 2 age groups have also been identified (group A, 65–70 years old vs group B, 71–76 years old).Donor and recipient characteristics were analyzed. Other parameters were cold and warm ischemia times, delayed graft function, biopsy-proven acute rejection, and causes of death.Induction immunosuppressive therapy was performed with basiliximab or thymoglobulin. Baseline triple immunosuppression included calcineurin inhibitor, antimetabolite, and steroids.The results of preimplantation biopsies, which were performed in all expanded criteria donors were analyzed and graded according to Karpinski 2009 classification. ResultsOverall mortality was 39.4%: 23.2% women and 76.8% men. Causes of death were infections in 42%, tumors in 23%, cardiovascular disease in 14%, cerebrovascular disease in 7%, and unknown in 14%. The most common cause of death in men was infections (52%), and the most common cause in women was tumors (55%).At 1, 3, 5, and 10 years, overall patient survival was 89%, 84%, 72%, and 45%, and overall graft survival was 100%, 97%, 89%, and 84%, respectively. Patient and graft survival were statistically different between group A vs group B (P = .006 and P = .02, respectively). At univariate analysis significant risk factors for increased mortality were age, delayed graft function, and cold ischemia time. At multivariate analysis, delayed graft function maintained statistical significance. ConclusionsKidney transplantation in patients older than 65 years is safe, feasible, and has good graft survival. Mortality is statistically significant in patients older than 71 years, despite a persistent low graft loss.
