Background Acute kidney injury (AKI) is still diagnosed by measuring the estimated creatinine clearance (eCCl), despite the fact that it may not change until 50% or more of kidney function has been lost. AKI after cardiac surgery is related to prolonged intensive care, decreased quality of life, and increased long term mortality. Neutrophil gelatinase-associated lipocalin (NGAL) represents an early biomarker of AKI, which may be useful for assessing AKI in cardiac patients.Objective To determine the validity of urinary and plasma NGAL as biomarkers for AKI in children after cardiac surgery.Methods Subjects were children who underwent cardiac surgery in Dr. Soetomo Hospital, Surabaya, Indonesia from August 2013 to January 2014. Serial urine and blood samples were analyzed for NGAL before surgery, as well as at 2h, 4h, 12h, and 24h after surgery. The AKI was established based on pRIFLE criteria. Estimated creatinine clearance (eCCl) was calculated from the estimated glomerular filtration rate (eGFR), according to age by the traditional Schwartz formula. Serum creatinine was assayed by the Jaffe method before surgery, as well as at 12h, 24h, 48h, and 72h after surgery.Results Of 20 subjects, 5 developed AKI. Urinary and plasma NGAL increased markedly at 2h postoperatively, as compared to eGFR which showed a rise at 12-48 h after cardiac surgery. Analysis of 2h post-operative urinary NGAL at a cut off value of 11.270ng/mL yielded an area under the curve (AUC) of 1.00 (95%CI 2.63 to 12.13), with sensitivity and specificity of 100% each for AKI. In addition, 2h post-operative plasma NGAL at a cut off value of 8.385 ng/mL yielded an AUC of 1.00 (95%CI 3.71 to 12.15) with sensitivity and specificity of 100% each for AKI.Conclusion Urinary and plasma NGAL are valid as early biomarkers for AKI in children after cardiac surgery.

Objective. Neutrophil gelatinase-associated lipocalin (NGAL) measured by a research ELISA is described as an early marker of acute kidney injury (AKI). The aim of this study is to define the usefulness of plasma NGAL (pNGAL) and urine NGAL (uNGAL) measured with platform analysers to detect AKI 3 hours after cardiac surgery in fifty adult patients. Methods and Main Results. pNGAL and uNGAL were measured before and 3 hours after cardiac surgery. AKI, defined following the acute kidney injury network definition, was observed in 17 patients. pNGAL was >149 ng/mL in 8 patients with AKI, two of them died in the follow-up. We also observed elevated pNGAL in 8 patients without AKI. Only one uNGAL was >132 ng/mL among the 15 AKI patients. Sensitivity of pNGAL for prediction of AKI is 47% and specificity is 75.7%. The positive likelihood ratio (LR+) is 1.9 and negative likelihood ratio (LR−) is 0.7. uNGAL performance is slightly improved when reported to urinary creatinine. Following this study, a ratio >62 ng/mg assure a sensitivity of 66.6% and a specificity of 78.5%. LR+ is 3 and a LR− is, 0.42. Conclusions. Three hours after cardiac surgery, pNGAL predicts AKI with a low sensitivity and specificity.
