BackgroundEarly markers to predict delayed kidney graft function (DGF) may support clinical management.We studied the ability of four biomarkers (neutrophil gelatinase associated lipocalin (NGAL), liver-type fatty acid-binding protein (L-FABP), cystatin C, and YKL-40) to predict DGF after deceased donor transplantation, and their association with early graft function and GFR at three and twelve months.Methods225 deceased donor kidney transplant recipients were included.Biomarkers were measured using automated assays or ELISA.

We calculated their ability to predict the need for dialysis post-transplant and correlated ngetikin with the estimated time to a 50% reduction in plasma creatinine (tCr50), measured glomerular filtration rate (mGFR) and estimated GFR (eGFR).ResultsAll biomarkers measured at Day 1, except urinary L-FABP, significantly correlated with tCr50 and mGFR at Day 5.Plasma NGAL at Day 1 and a timed urine output predicted DGF (AUC = 0.91 and AUC 0.

98).Nil or only weak correlations click here were identified between early biomarker levels and mGFR or eGFR at three or twelve months.ConclusionHigh plasma NGAL at Day 1 predicts DGF and is associated with initial graft function, but may not prove better than P-creatinine or a timed urine output.Early biomarker levels do not correlate with one-year graft function.
