Two cases of kidney transplantation from the same non-heart beating deceased donor after long cold-ischemic time more than 24 h

Introduction: After nearly four years of Canadian experience with medical assistance in dying (MAiD), the clinical volume of organ transplantation following MAiD remains low. This is the first Canadian report evaluating recipient outcomes from kidney transplantation following MAiD. Methods: This was a retrospective review of the first nine cases of kidney transplants following MAiD at a Canadian transplant center. Results: Nine patients underwent MAiD followed by kidney retrieval during the study period. Their diagnoses were largely neuromuscular diseases. The mean warm ischemic time was 20 minutes (standard deviation [SD] 7). The nine recipients had a mean age of 60 (SD 19.7). The mean cold ischemic time was 525 minutes (SD 126). Delayed graft function occurred in only one patient out of nine. The mean 30-day creatinine was 124 umol/L (SD 52) . The mean three-month creatinine was 115 umol/L (SD 29). Conclusions: We report nine cases of kidney transplantation following MAiD. The process minimized warm ischemia, resulting in low delayed graft function rates, and acceptable post-transplant outcomes. Further large-scale research is necessary to optimize processes and outcomes in this novel clinical pathway.

Deceased Donor Kidney Transplantation

Abstract Background Delayed graft function (DGF) is closely associated with the use of marginal donated kidneys due to deficits during transplantation and in recipients. We aimed to predict the incidence of DGF and evaluate its effect on graft survival. Methods This retrospective study on kidney transplantation was conducted from January 1, 2018, to December 31, 2019, at the Second Xiangya Hospital of Central South University. We classified recipients whose operations were performed in different years into training and validation cohorts and used data from the training cohort to analyze predictors of DGF. A nomogram was then constructed to predict the likelihood of DGF based on these predictors. Results The incidence rate of DGF was 16.92%. Binary logistic regression analysis showed correlations between the incidence of DGF and cold ischemic time (CIT), warm ischemic time (WIT), terminal serum creatine (Scr) concentration, duration of pretransplant dialysis, primary cause of donor death, and usage of LifePort. The internal accuracy of the nomogram was 83.12%. One-year graft survival rates were 93.59 and 99.74%, respectively, for the groups with and without DGF (P < 0.05). Conclusion The nomogram established in this study showed good accuracy in predicting DGF after deceased donor kidney transplantation; additionally, DGF decreased one-year graft survival.
