Abstract:

 Background & Objective:  Chronic Kidney Disease (CKD) has been recognized as a serious public health threat. The early detection of kidney damage in CKD is a useful way to reduce the disease burden. This study aimed to determine the power of Neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C (Cys-C) to predict the kidney damage in Iranian patients.  Materials & Methods:  This study was conducted at Shohadaye Tajrish Hospital on 72 renal patients. The estimated glomerular filtration rate (GFR) was assumed as the gold standard method. The NGAL and Cys-C were used as predictors and estimated GFR was used as a response variable. Three logistic regression models were fitted to investigate the impact of single and multiple markers for the prediction of GFR status. Results:  The regression models with NGAL and Cys-C as single predictors, and with both of them as multivariate predictors, were fitted to the data. The markers except for Cys-C were significantly related to the renal damage in all models (P<0.05). The obtained odds ratio for the model with NGAL, Cys-Cand both NGAL and Cys-C were 1.142, 1.004 and 1.125, respectively. The sensitivity and specificity of the models with NGAL, Cys-C and both of them were 96.00 and 100.00; 64.00 and 97.87; and 96.00 and 100, respectively.  Conclusion:  Our findings revealed that the NGAL biomarker as a single predictor could result in high predictor power for classifying the patients with and without kidney damage. Thus, the clinicians can use this marker for the early prediction of this renal problem.

Predictive Values of Urinary Interleukin 18 and Neutrophil Gelatinase-Associated Lipocalin for Delayed Graft Function Diagnosis in Kidney Transplantation

Background: Delayed graft function is a main complication after deceased donor kidney transplantation that adversely affects graft outcome. Difficulties in prediction and early detection of delayed graft function have hindered the ability to perform proper therapeutic interventions. We investigated whether measuring urinary interleukin 18 and neutrophi...

Plasma neutrophil gelatinase-associated lipocalin for the prediction of acute kidney injury in acute heart failure

INTRODUCTION The accurate prediction of acute kidney injury (AKI) in patients with acute heart failure (AHF) is an unmet clinical need. Neutrophil gelatinase-associated lipocalin (NGAL) is a novel sensitive and specific marker of AKI. METHODS A total of 207 consecutive patients presenting to the emergency department with AHF were enrolled. Plasma NGAL was measured in a blinded fashion at pres...

Neutrophil Gelatinase-Associated Lipocalin and Kidney Diseases

Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as one of the most promising biomarkers of renal epithelial injury. Numerous studies have presented the diagnostic and prognostic utility of urinary and plasma NGAL in patients with acute kidney injury, chronic kidney disease, renal injury after kidney transplantation, and other renal diseases. NGAL is a member of the lipocalin famil...
