The Predictive value of serum NGAL for the diagnosis of Delayed Graft Function in kidney transplantation [post]

2020 unpublished
and aims the role of serum neutrophil gelatinase-associated lipocalin (NGAL) in predicting delayed graft function (DGF) after kidney transplantation is poorly defined. The objective of this study was to evaluate the serum NGAL expression in the early postoperative phase after kidney transplantation and compare it with serum creatinine (Cr). Methods We studied 32 patients who received kidney transplantation from deceased (n=24) and live (n=5) donors during , Iran. Serum NGAL, Serum Cr and urine

Results Among 29 recipients with serum biomarkers measurements, 8 (27.5%) developed DGF (need to hemodialysis within 1 week of transplantation). Resulted in areas under ROC curves (AUCs) for serum NGAL at early hours following transplantation was (0.839, 95% CI: 0.69-0.98, P =0.005) that could accurately predict DGF compared to urine output (0.747, 95% CI: 0.55-0.93, P =0.045) and serum Cr (0.607, 95% CI: 0.34-0.86, P =0.398) at 24 hours after transplantation. Multivariate analysis revealed that only serum NGAL was significant independent predictor of DGF (OR: 0.996, 95% CI: 0.993-1.000, P =0.039). Conclusion Serum NGAL at early hours of post-transplantation was valuable biomarker for early accurate predictor of DGF in kidney transplantation compare with tradition biomarkers such as serum Cr and urine output.
