BACKGROUND: This single-center study sought to examine the clinical outcomes of kidney transplant recipients from donors displaying acute kidney injury (AKI).
METHODS: We analyzed retrospectively the medical records of the donors and recipients of 54 deceased-donor kidney transplantations performed in our center between March 2009 and March 2012.
RESULTS: Among the 54 deceased donors, 36 (66.7%) experienced AKI as determined by the final mean serum creatinine levels measured before graft harvest of 2.66 ± 1.62 mg/dL versus 0.82 ± 0.28 mg/dL among non-AKI donors. The risks of delayed graft function and slow graft function were increased among the AKI versus non-AKI groups in the early post-transplantation period. However, the renal function status of recipients at 3, 6, and 12 months after transplantation was not significantly different between the two groups. Moreover, rejection-free survival rates during the study period were similar. Multivariate analysis revealed an acute rejection episodes (P = .047) and a lower body mass index in the donor relative to the recipient (P = .011) to be independent risk factors predicting poor graft function defined as a 1-year estimated glomerular filtration rate less than 50 mL/min/l.73 m(2). Donor AKI with either a high level (>4.0 mg/dL), an increasing trend of creatinine, or greater severity by the Risk, Injury, Failure, Loss, and End-stage kidney disease (RIFLE) classification was not a significant risk factor.
CONCLUSION: Transplantation of kidneys from the AKI donors, namely, patients with severely decreased renal function, displayed excellent short-term outcomes. Accordingly, kidney transplantations from deceased donors with AKI should be considered more actively to expand the donor pool in Korea.
