Serum Neutrophil Gelatinase-Associated Lipocalin Levels In Early Detection Of Contrast-Induced Nephropathy.

Abstract

The purpose of this study was to investigate the role of serum neutrophil gelatinase-associated lipocalin (NGAL) levels in the early detection of contrast-induced nephropathy (CIN). This prospective study enrolled 74 patients undergoing abdominal tomography with contrast (1 November 2014 - 28 February 2015). Demographic properties (age and sex), symptoms and CT examination results were analysed. Sodium, potassium, urea, creatinine and NGAL levels were measured at 0th, 6th, and 72nd hours. P value < 0.05 was considered statistically significant. CIN developed in 16.2% of the study patients. The mean age was significantly higher in the patients who developed CIN (p0.05). Urea levels did not differ significantly between the groups at 0th and 6th hours (p>0.05) but was significantly higher in the patients with CIN at 72nd hour (p0.05). Creatinine level was not significantly different between the groups (p>0.05) but increased significantly over time (p>0.05). There were no significant differences between the groups with respect to NGAL levels at 0th and 72nd hours(p>0.05) whereas the group with CIN had a significantly higher NGAL level at 6th hour (p.
