Neutrophil Gelatinase Associated Lipocalin (NGAL) as a Biomarker. Does It Apply in Abdominal Aortic Aneurysms? A Review of Literature.

Neutrophil gelatinase associated lipocalin (NGAL) as a protein derived from neutrophils has recently been the field of investigation in a wide range of diseases (renal disease, coronary artery disease, etc). The MEDLINE/PubMed database was searched for publications with the medical subject heading "NGAL" and keywords "Abdominal aortic aneurysm (AAA)," "biomarker," and "growth". We restricted our search to date.

Urine NGAL as a biomarker of kidney damage after on- and off-pump coronary artery bypass graft surgery: a prospective pilot study.

Introduction: Acute kidney injury (AKI) is a relatively frequent complication after coronary artery bypass graft surgery (CABG). We compared the off- and on-pump CABG procedures with respect to changes in renal function as reflected by levels of urine neutrophil gelatinase-associated lipocalin (UrNGAL).

Methods: In a prospective design, we studied patients who underwent CABG, off- or on-pump, with respect to changes in glomerular filtration rate (GFR) and UrNGAL pre- and postoperatively.
