BackgroundOrgan shortage has prompted the use of expanded-criteria donors (ECDs). Our objective was to compare long-term outcomes of kidney transplants from ECDs with those from concurrent standard-criteria donors (SCDs). In addition, we evaluated variables associated with graft survival in both groups.MethodsWe retrospectively reviewed all 617 deceased-donor kidney transplantations performed from 2005 to 2009 in our department. The population was divided according to donor status into ECD or SCD. Patients were followed until 5 years after transplantation, death, graft failure, or loss to follow-up.ResultsWe transplanted 150 deceased-donor kidneys from ECDs and 467 from SCDs. ECD were older, more frequently women, had a lower pre-retrieval glomerular filtration rate, and more frequently died due to cerebrovascular accident. ECD recipients were older, presented a lower proportion of black race, more frequently were on hemodialysis, and presented a higher rate of first kidney transplants. Mean glomerular filtration rate was consistently lower in the ECD group. Patient and graft survivals were lower in the ECD group, but statistical significance was present only in graft survival censored for death with a functioning graft at 3 years and graft survival noncensored for death with a functioning graft at 5 years. Younger recipient ages, longer time on dialysis, acute rejection episodes, and glomerular filtration rate at 1 year after transplantation were independent risk factors for lower graft survival.ConclusionsTransplantation with the use of ECD kidneys provide quite satisfactory patient and graft survival rates despite their poorer long-term outcomes.Copyright © 2017 Elsevier Inc.
