- Abstract
Objective To evaluate the predictive values of serum neutrophil gelatinase-associated lipocalin (NGAL), urine NGAL, serum cystatin C (Cys-C) and serum creatinine (Scr) for early delayed graft function (DGF) in kidney transplant recipients. Methods Clinical data, blood and urine samples of 159 kidney transplant recipients were collected. All recipients were divided into the DGF group (n=42) and immediate graft function (IGF) group (n=117) according to the incidence of DGF. Clinical data of all recipients were analyzed. The changes of serum NGAL, urine NGAL, Cys-C and Scr levels were statistically compared between two groups. The predictive values of different markers for early DGF were assessed. Results Among 159 kidney transplant recipients, DGF occurred in 42 cases with an incidence rate of 26.4%. There were statistically significant differences in donor age, cold ischemia time of donor kidney and complement-dependent cytoxicity (CDC) between the two groups(all P<0.05). Within postoperative 2 weeks, the serum NGAL levels in the DGF group were higher than those in the IGF group (all P<0.05). The Cys-C, Scr and urine NGAL levels in the DGF group were higher compared with those in the IGF group within 3 weeks after kidney transplantation(all P<0.001). Serum NGAL, urine NGAL, Cys-C and Scr levels had certain predictive values for early DGF in kidney transplant recipients. Cys-C yielded the highest predictive value with a cut-off value of 4.73 mg/L, sensitivity of 0.833, specificity of 0.812 and area under the curve (AUC) of 0.895. Conclusions Cys-C has higher predictive value for early DGF in kidney transplant recipients compared with serum NGAL, urine NGAL and Scr.
