assessment of neutrophil gelatinase-associated lipocalin (ngal) as an early biomarker for detection of renal impairment in hypertensive patients
نویسندگان
چکیده
chronic kidney disease (ckd) is probably the most important problem of public health in advanced countries. kidneys are often damaged as a result of high blood pressure. one of our main concerns in patients with hypertension is early detection of kidney disorders. the routine biomarkers such as creatinine have some limitation for this purpose, however recent studies suggest plasma ngal to be a better marker. therefor in this study we assessed the diagnostic value of plasma ngal and compared it with serum creatinine in hypertensive patients. this study was performed on 42 hypertensive patients and 30 healthy volunteer, both with normal serum creatinine and urea concentration who referred to shohada tajrish hospital, plasma ngal were measured subsequently using elisa method and egfr was considered as the gold standard method(cut off value of<78ml.min.1.73m 2 ). mean ngal level was significantly higher in patients in comparison to control group. the sensitivity and specificity were 96% and 100% respectively for plasma ngal(≥32.2 ng/ml) compared with 76% and 47% for serum creatinine (>0.97 mg/dl). our findings indicate that ngal is a better indicator of kidney impairment in the early stages of ckd as compared with serum creatinine in hypertensive patients.

Comparative Assessment of Neutrophil Gelatinase-Associated Lipocalin (NGAL) and Cystatin C as Early Biomarkers for Early Detection of Renal Failure in Patients with Hypertension
Background: Hypertension is one the most common causes of chronic kidney disease (CKD). One of the major concerns in hypertensive patients is early detection of renal disorders. In the past, serum creatinine (Scr) concentration was used as a marker of kidney function, but it proffers a late reflection of reduced glomerular filtration rate. Cystatin C and neutrophil gelatinase-associated lipocal...

BACKGROUND The scarcity of early biomarkers for acute renal failure has hindered our ability to launch preventive and therapeutic measures for this disorder in a timely manner. We tested the hypothesis that neutrophil gelatinase-associated lipocalin (NGAL) is an early biomarker for ischaemic renal injury after cardiopulmonary bypass. METHODS We studied 71 children undergoing cardiopulmonary b...

Background: Diabetic nephropathy is a common complication of diabetes mellitus type2. The neutrophil gelatinase Associated lippocallin (NGAL) is an ubiquitous protein consist of 178 amino acid. NGAL can be identified in plasma and urine starting 24 hours after a kidney injury resulting changes in glomerular filtration and tubular reabsorption and with increased secretion in tubular epithelial c...
متن کاملIdentification of neutrophil gelatinase-associated lipocalin as a novel early urinary biomarker for ischemic renal injury.
Acute renal failure (ARF) secondary to ischemic injury remains a common and potentially devastating problem. A transcriptome-wide interrogation strategy was used to identify renal genes that are induced very early after renal ischemia, whose protein products might serve as novel biomarkers for ARF. Seven genes that are upregulated >10-fold were identified, one of which (Cyr61) has recently been...
