The elderly are the fastest-growing population on waiting lists for kidney transplantation (KTx). Recognized barriers to KTx in the elderly is early post-transplant mortality and morbidity. To analyze the outcomes of KTx in recipients older than 60 years and, simultaneously, in their younger paired recipients, receiving a graft from the same donor.We included 328 kidney transplant recipients in the study. The elderly kidney transplant recipients (EKT) group included 164 patients aged 65 standard deviation (SD4) years. They were paired with younger kidney transplant recipients (YKT) aged 45 (SD12) years.The studied groups (EKT vs YKT) did not differ from the graft function estimated 1 year after the transplantation (50.7 mL/min vs 54.0 mL/min), while the estimated glomerular filtration rate decline was significantly faster in the YKT group. One-year patient survival (93.9% vs 97.0%), 1-year graft survival (90.4% vs 82.3%), and incidences of delayed graft function and acute rejection did not differ between the EKT and YKT groups. Significantly more cardiovascular complications and post-transplant diabetes mellitus were noticed in the EKT group. The long-term patient and graft survivals were poorer in the EKT group versus the YKT group, but death-censored graft survivals were the same. After having excluded donor-derived graft factors, there were no differences in the first-year outcome of KTx between recipients younger and older than 60 years. As life expectancy is lower in the EKT group, the probability of patient and graft survival was also significantly lower in this group. However, death-censored graft survival was not different in the EKT and YKT groups.Copyright © 2021 the Author(s). Published by Wolters Kluwer Health, Inc.
