Résumé
This study examined 1071 adult primary kidney transplants from the French-controlled donation after the circulatory determination of death (cDCD) program, which uses normothermic regional perfusion (NRP), and involves short cold ischemia times (CIT) and constrained asystole times differing by donor age. Logistic regression identified risk factors for primary nonfunction (PNF), delayed graft function (DGF), and graft failure. Risk factors for PNF included donor hypertension, admission for ischemic vascular stroke, and HLA DR mismatches. Risk factors for DGF included functional warm ischemia time >40 min, dialysis >2 y, recipient body mass index of 30 kg/m2 or higher, recipient diabetes, and CIT >10 h. Risk factors for 1-y graft failure included donor hypertension, donor lung recovery, ostial calcification, recipient cardiovascular comorbidities, and HLA DR mismatches. A high donor estimated glomerular filtration rate protected against DGF and graft failure at 1-y. After adjustment restricted to recipient and graft factors and donor age, the risks of PNF, DGF, and graft failure increased with donor age up to 65 y and then remained stable. The study suggests that cDCD kidney transplants are highly successful, but also that its outcomes are influenced by lung recovery, poor HLA DR matching, and warm ischemia times differing with donor age. Our study identified several risk factors for kidney transplantation failure after cDCD with systematic use of NRP and some of them seem as modifiable variables associated with cDCD transplant outcome.

BACKGROUND
BACKGROUND
This study examined 1071 adult primary kidney transplants from the French-controlled donation after the circulatory determination of death (cDCD) program, which uses normothermic regional perfusion (NRP), and involves short cold ischemia times (CIT) and constrained asystole times differing by donor age.
METHODS
METHODS
Logistic regression identified risk factors for primary nonfunction (PNF), delayed graft function (DGF), and graft failure.
RESULTS
RESULTS
Risk factors for PNF included donor hypertension, admission for ischemic vascular stroke, and HLA DR mismatches. Risk factors for DGF included functional warm ischemia time >40 min, dialysis >2 y, recipient body mass index of 30 kg/m2 or higher, recipient diabetes, and CIT >10 h. Risk factors for 1-y graft failure included donor hypertension, donor lung recovery, ostial calcification, recipient cardiovascular comorbidities, and HLA DR mismatches. A high donor estimated glomerular filtration rate protected against DGF and graft failure at 1-y. After adjustment restricted to recipient and graft factors and donor age, the risks of PNF, DGF, and graft failure increased with donor age up to 65 y and then remained stable.
CONCLUSIONS
CONCLUSIONS
The study suggests that cDCD kidney transplants are highly successful, but also that its outcomes are influenced by lung recovery, poor HLA DR matching, and warm ischemia times differing with donor age. Our study identified several risk factors for kidney transplantation failure after cDCD with systematic use of NRP and some of them seem as modifiable variables associated with cDCD transplant outcome.
