We studied whether donor neutrophil gelatinase-associated lipocalin NGAL a novel biomarker for acute kidney injury could predict DGF after transplantation. Methods We included 99 consecutive deceased donors and their 176 kidney recipients. For NGAL detection donor serum and urine samples were collected before the donor operation. The samples were analyzed using a commercial enzyme-linked immunosorbent assay kit serum and the ARCHITECT method urine . Results Mean donor serum NGAL S-NGAL concentration was 218 ng mL range 27 to 658 standard deviation SD 145.1 and mean donor urine NGAL U-NGAL concentration was 18 ng mL range 0 to 177 SD 27.1 . Donor S-NGAL and U-NGAL concentrations correlated directly with donor plasma creatinine levels and indirectly with estimated glomerular filtration rate eGFR calculated using the modification of diet in renal disease equation for glomerular filtration rate. In transplantations with high greater than the mean donor U-NGAL concentrations prolonged DGF lasting longer than 14 days occurred more often than in transplantations with low less than the mean U-NGAL concentration 23 vs. 11 P 0.028 and 1-year graft survival was worse 90.3 vs. 97.4 P 0.048 . High U-NGAL concentration was also associated with significantly more histological changes in the donor kidney biopsies than the low U-NGAL concentration. In a multivariate analysis U-NGAL expanded criteria donor status and eGFR emerged as independent risk factors for .
