BACKGROUND Neutrophil gelatinase-associated lipocalin (NGAL), an iron-transporting protein rapidly accumulating in the kidney tubules and urine after nephrotoxic and ischemic insults, has been put forward as an early, sensitive, non-invasive biomarker for acute kidney injury (AKI). The aim of this study was to evaluate urinary NGAL levels as a predictor of early AKI (first 5 days after injury) ...

BACKGROUND Neutrophil gelatinase-associated lipocalin (NGAL) is an early marker of kidney injury. We sought to assess the prognostic value of this biomarker in patients with stable chronic heart failure (HF). METHODS We studied 61 patients with chronic systolic HF who had been receiving optimal medical treatment for at least six months. Biomarkers were measured at baseline and included plasma...

Neutrophil gelatinase-associated lipocalin (NGAL) is a 25 kD lipocalin that is covalently bound to matrix metalloproteinase (MMP)-9 produced by neutrophils [1]. NGAL in blood or bronchoalveolar lavage fluid (BALF) may reflect neutrophilic inflammation in the lungs [2, 3], and it is highly induced in injured epithelial cells, including those in the lung [4]. Possible roles for neutrophilic infla...

Extracorporeal circulation (ECC) used during cardiac surgery causes activation of several inflammatory systems. These events are not fully understood but are responsible for complications during the immediate postoperative period. Neutrophil gelatinase-associated lipocalin (NGAL), a member of the expanding lipocalin family, has recently been described as an inflammatory protein. In this study, ...

Acute kidney injury (AKI) is a complex, frequent and serious clinical problem with high rate of mortality. Therefore there is a serious need for early detection of AKI, with a tendency to detect early stage--RISK dut to start with therapy as soon as possible and prevent irreversible changes in renal function. Study's purposes were to explore the rhythm of urine neutrophile gelatinase associated...

Acute renal failure secondary to ischemic injury remains a common problem, with limited and unsatisfactory therapeutic options. Neutrophil gelatinase-associated lipocalin (NGAL) was recently shown to be one of the maximally induced genes early in the postischemic kidney. In this study, the role of NGAL in ischemic renal injury was explored. Intravenous administration of purified recombinant NGA...

Delayed graft function (DGF) due to tubule cell injury frequently complicates deceased donor kidney transplants. We tested whether urinary neutrophil gelatinase-associated lipocalin (NGAL) and interleukin-18 (IL-18) represent early biomarkers for DGF (defined as dialysis requirement within the first week after transplantation). Urine samples collected on day 0 from recipients of living donor ki...

INTRODUCTION Neutrophil gelatinase-associated lipocalin (NGAL) has been identified as a biomarker of acute kidney injury (AKI) that could contribute to early diagnosis and effective management of AKI. The purpose of this study was to evaluate NGAL as a predictive marker of AKI in patients with clinically severe obesity (BMI >50) who underwent biliopancreatic diversion surgery. PATIENTS AND ME...
