Background: No specific early biomarker is available to measure kidney injury after kidney transplantation (KT). Both neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury marker 1 (KIM-1) increase after oxidative injury. Their potential as early biomarkers was evaluated in this one-arm pilot study. Materials and Methods: Twenty consecutive KT patients receiving a kidney from a donation after circulatory death donor were included. Graft perfusate was collected, as well as serum samples before transplantation, at the end of surgery, and 1, 4, and 7 days after transplantation. NGAL and KIM-1 were measured using ELISA. Kidney function and delayed graft function (DGF) were monitored. Results: In this cohort, 85% of the KT patients developed DGF. Perfusate NGAL correlated with donor age (r2 = 0.094, p = 0.01) and serum creatinine (r2 = 0.243, p = 0.05). A cardiac cause of death was associated with higher NGAL in the perfusate (p = 0.03). Serum NGAL at day 1 was significantly higher in patients with DGF (730 ng/ml, range 490-1,655, vs. 417 ng/ml, range 232-481; p = 0.01). Serum NGAL levels at day 1, 4, and 7 correlated with the duration of DGF. KIM-1 was not detectable in the perfusate or in the serum until postoperative day 4 in 80% of patients. Conclusions: NGAL in the perfusate correlates with known donor risk factors for DGF. For the first time, we describe that serum NGAL at day 1 can discriminate between DGF and immediate graft function. Also, serum NGAL levels at day 1, 4, and 7 correlate with the duration of DGF. No association with KIM-1 was found. These data suggest that NGAL may be used as an early biomarker to detect DGF and warrants further study.

Introduction: Delayed graft function and acute rejection have negative impact on graft survival. Aim: To asses the predictive value of urinary neutrophil gelatinase-associated lipocalin, which has been found to be a promising biomarker for the diagnosis of acute kidney injury. Method: In this prospective study urinary neutrophil gelatinase-associated lipocalin levels of 27 kidney recipients were measured. Results: Patients were grouped as follows: group 1, no complication; group 2, rejection; group 3, delayed graft function requiring dialysis; group 4, rejection plus delayed graft function. There were no significant differences between groups 1 and 2, and between groups 3 and 4. Patients in groups 3 and 4 had significantly higher urinary neutrophil gelatinase-associated lipocalin levels as compared to those in groups 3 and 4. There was a paralIel change in urinary neutrophil gelatinase-associated lipocalin levels in groups 1 and 2. Conclusions: In these patients urinary neutrophil gelatinase-associated lipocalin levels failed to provide useful information in both cases of normal and impaired function. Orv.

Abstract Background: Delayed graft function is a major determinant of long-term renal allograft survival. Despite considerable efforts to improve donor selection and matching, incidence of delayed graft function remains close to 25%. As neutrophil gelatinase-associated lipocalin (NGAL) has been shown to predict acute renal failure, the authors tested the hypothesis that NGAL measurement in brain-dead donors predicts delayed graft function in kidney recipients. Methods: In a prospective, multicenter, observational study, serum NGAL was measured in donors at the time of transfer to operating room. The primary endpoint was the delayed graft function, defined as the need for renal replacement therapy during the first week posttransplantation. Results: Among 159 included brain-dead donors, 146 were analyzable leading to 243 renal transplantations. Of these, 56 (23%) needed renal replacement therapy. Donors’ NGAL values were similar in case of both delayed and normal graft function in recipients. The area under the receiver-operating curve for NGAL to predict the need for renal replacement therapy before day 8 was 0.50 (95% CI, 0.42 to 0.59). The area under curve for NGAL to predict failure to return to a normal graft function at day 8 was 0.51 (95% CI, 0.44 to 0.59). Using multivariate analysis, NGAL was not associated to the need for renal replacement therapy (odds ratio, 0.99; 95% CI, 0.98 to1.00) or failure to return to a normal graft function at day 8 (odds ratio, 1.00; 95% CI, 0.99 to 1.00). Conclusion: NGAL measurement in brain-dead donors at the time of recovery failed to predict delayed or normal graft function in kidney recipients.
