Utilization of Donor Kidneys With Acute Kidney Injury in Pediatric Kidney Transplant Recipients

Background. An elevated terminal creatinine is frequently used as a reason for organ refusal in pediatric kidney transplantation. There is increasing evidence that adults who receive kidneys from donors with moderate to severe acute kidney injury (AKI) have similar outcomes to recipients who receive kidneys from donors with none to mild AKI. Methods. We used the Scientific Registry of Transplant Recipients to determine how many pediatric kidney transplant recipients developed delayed graft function (DGF) between 2000 and 2010. Results. When stratified by the donor terminal creatinine, there was no significant difference in the recipient discharge creatinine or the likelihood of developing DGF. In a logistic regression model, older donor age, male donors, and a longer cold ischemia time but not donor terminal creatinine were independent predictors of DGF. There were very few graft loss events documented in this study. Conclusions. Our results are in agreement with previously published data; a high donor terminal creatinine is not significantly associated with DGF in pediatric renal transplant recipients. Additional studies investigating the risk of rejection and long-term graft function are needed before adopting the practice of accepting kidneys with moderate to severe AKI in pediatric kidney transplant recipients.
