Aim: The aim of the present study was to investigate the clinical outcomes of kidney transplantation (KT) in elderly recipients compared with those in young recipients. Methods: We compared the incidence of biopsy-proven acute rejection, death-censored allograft survival and all-cause mortality, and also compared the impact of high sensitization or desensitization on the clinical outcomes of elderly and young recipients. Results: A total of 4966 KT recipients from the Korean Organ Transplantation Registry were included. The definition of elderly recipients was based on age >60 years (n = 356), and recipients aged <60 years were defined as young recipients (n = 4610). The incidence of biopsy-proven acute rejection did not differ between the two groups irrespective of the donor type; however, the impact of high sensitization was significant only in young recipients. Being an elderly recipient was an independent risk factor for death-censored allograft failure in terms of overall and living donor KT, but not with deceased donor KT. In regard to patient death, being an elderly recipient was a significant predictor in general and in the two subgroups, and desensitization showed a significant interaction with death in the elderly recipients in the living donor KT group. Conclusions: In conclusion, KT in elderly recipients might be associated with poor allograft or patient survival in general, and especially, desensitization therapy carried out in these patients might increase the risk of patient mortality.
