Résumé
Deceased donor kidneys with acute kidney injury (AKI) and donation after circulatory death (DCD) kidneys are viable sources of organs. The outcomes of renal transplantation from DCD donors with AKI are not known. A retrospective review of deceased donor renal transplants performed from 2006 to 2016 was conducted using the United Network for Organ Sharing dataset. Donors were stratified by DCD or brain dead status and by AKI stage. Recipients were followed until graft failure or the end of study. Cox regression was used to adjust for donor, recipient, and transplant covariates known to affect the incidence of delayed graft function and graft survival. A total of 135 644 patients were included in the study. The odds of delayed graft function among DCD recipients were significantly higher across all donor AKI stages. The unadjusted risk of overall and death-censored graft failure were similar between the 2 groups. After adjusting for covariates, there was a significant increase in the risk of overall graft failure in recipients of DCD allografts from donors with stage 2 AKI. There was also a higher risk of death-censored graft failure among stage 1 and 2 AKI DCD recipients. DCD renal allografts from donors experiencing stage 1 and 2 AKI have a higher adjusted risk of death-censored graft failure than AKI stage-matched donation after brain death renal allografts. Their use, however, is still associated with improved outcomes compared with waitlist mortality.

BACKGROUND
Deceased donor kidneys with acute kidney injury (AKI) and donation after circulatory death (DCD) kidneys are viable sources of organs. The outcomes of renal transplantation from DCD donors with AKI are not known.
METHODS
A retrospective review of deceased donor renal transplants performed from 2006 to 2016 was conducted using the United Network for Organ Sharing dataset. Donors were stratified by DCD or brain dead status and by AKI stage. Recipients were followed until graft failure or the end of study. Cox regression was used to adjust for donor, recipient, and transplant covariates known to affect the incidence of delayed graft function and graft survival.
RESULTS
A total of 135 644 patients were included in the study. The odds of delayed graft function among DCD recipients were significantly higher across all donor AKI stages. The unadjusted risk of overall and death-censored graft failure were similar between the 2 groups. After adjusting for covariates, there was a significant increase in the risk of overall graft failure in recipients of DCD allografts from donors with stage 2 AKI. There was also a higher risk of death-censored graft failure among stage 1 and 2 AKI DCD recipients.
CONCLUSIONS
DCD renal allografts from donors experiencing stage 1 and 2 AKI have a higher adjusted risk of death-censored graft failure than AKI stage-matched donation after brain death renal allografts. Their use, however, is still associated with improved outcomes compared with waitlist mortality.
