P1690EXPERIENCE WITH EXPANDED CRITERIA DONORS: 10-YEAR SINGLE CENTER ANALYSIS

Background and Aims Kidneys from expanded criteria donors with diagnosis of brain death have become a part of the organ transplant program, which have thus increased the number of transplants. Method In this retrospective analysis, we identified the expanded criteria donors in a group of 156 kidney donors at our center. Basic parameters of the donors before kidney recovery were collected. Graft function, graft survival, and patient survival at 1, 3, and 5 years posttransplant were compared in expanded criteria versus standard criteria donors. Results Expanded criteria donors were significantly older than standard criteria donors (P < .001), had higher body mass index (P = .006), and had more frequent arterial hypertension (P < .001) and diabetes mellitus (P = .004) in their histories. When we considered the estimated glomerular filtration rate, graft function in the first 6 months after transplant was significantly worse in kidneys from expanded criteria donors (P = .011). In addition, recipients of grafts from expanded criteria donors had significantly worse survival in the first year posttransplant (P = .023); however, no differences in graft survival were observed. Conclusion From the long-term aspect, graft function and graft and patient survival in cases of kidneys from expanded criteria donors were comparable to results with kidneys from standard criteria donors. Expanded use of organs available for transplant is important due to the constantly increasing demands versus limited offers of organs.
