BACKGROUND: For the average patient with end-stage renal disease, kidney transplantation improves quality of life and prolongs survival compared with patients on the transplant waiting list who remain on dialysis. Patients ≥65 years of age represent an increasing proportion of adults with end-stage renal disease, and kidney transplantation outcomes remain controversial in this population. The aim of this study was to evaluate factors that may increase 1-year mortality after renal transplantation in older recipients.
METHODS: A retrospective study that included 147 patients (75.5% men) ≥65 years old (mean age 67.5 ± 2 years) who were transplanted between January 2011 and December 2020. The mean follow-up was 52.6 ± 27.2 months.
RESULTS: Rehospitalization (<1 year) occurred in 39.5% of patients. Infectious complications were present in 18.4% of patients. The overall mortality rate was 23.1%, and 1-year mortality was 6.8%. As 1-year mortality predictors, we found a positive correlation with factors related to kidney transplant, such as cold ischemia time (P = .003), increasing donor age (P = .001); and factors related to the receptor such as pretransplantation dialysis modality as peritoneal dialysis (P = .04), cardiovascular disease (P = .004), delayed graft function (P = .002), early cardiovascular complications after kidney transplant (P < .001), and early rehospitalizations (P < .001). No correlation was found between 1-year mortality and age, sex, race, body mass index, and type of kidney transplant.
CONCLUSION: A more rigorous pretransplant evaluation, focusing on cardiovascular disease and strict exclusion criteria, is recommended for patients ≥65 years old.
