OBJECTIVES: Kidney transplant is the optimal therapy for patients with end-stage renal disease. The presence of donor diabetes mellitus is a recognized risk factor for impaired kidney graft survival and is incorporated into the Kidney Donor Profile Index. At present, however, there are limited assessments of the severity of this risk factor. Hemoglobin A1c reflects glycemic control over the preceding 3 months, and we hypothesized that donor hemoglobin A1c levels could confer additional discriminatory power in assessments of deceased donors with diabetes mellitus.
MATERIALS AND METHODS: The United Network for Organ Sharing/Organ Procurement and Organ Transplantation Network Standard Transplant Analysis Research file was queried for adult deceased-donor kidney transplants performed using allografts from donors with diabetes mellitus who had measurements of hemoglobin A1c before donation.
RESULTS: The study cohort consisted of 1518 kidney transplants performed using allografts from deceased donors with diabetes mellitus. Kaplan-Meier survival analysis and log-rank test were performed to compare survival of grafts from donors with diabetes mellitus with elevated (≥ 6.5%) versus lower (< 6.5%) hemoglobin A1c levels. Graft survival at 5 years was significantly lower for recipients of donors with hemoglobin A1c ≥ 6.5% (58.9% vs 68.3%; P < .001). On multivariate analysis, hemoglobin A1c ≥ 6.5% was an independent predictor of diminished graft survival.
CONCLUSIONS: Hemoglobin A1c has potential as an additional discriminatory test for estimating outcomes of grafts from donors with diabetes mellitus and should be routinely measured in this population.
