Abstract

Detecting AKI in a timely fashion with the current AKIN staging criteria is a challenge because the diagnosis of AKI is usually based on changes in serum creatinine (SCr) which is a poor marker of early renal dysfunction

To study the role of Serum Neutrophil Gelatinase-Associated Lipocalcin (NGAL) as early biomarker for the detection of Contrast induced acute kidney injury (CIAKI) in subjects undergoing Percutaneous transluminal coronary angiogram (PTCA) with normal eGFR

Prospective cohort study was conducted, where SCr and serum NGAL were serially measured in a heterogeneous group of subjects (n=60) presenting to cardiology department

The study population consisted of 60 subjects. All subjects were divided into 2 groups “CIAKI group” and “no-CIAKI group” according to predefined definition. The serum NGAL increased and reached its peak at 4 hours after contrast media (CM) administration and did not returned to baseline by 24 hours while the SCr increased at 24 hours and reached peak at 48 hours respectively (P<0.001). Thus, 4 hours after CM administration were considered to be appropriate time point for NGAL measurement and there was no significant correlation between serum NGAL with SCr at 0 hours, 4hours, 24 hours and 48hours

In our study, we found that serum NGAL promises to be a simple, safe, non-invasive and reliable early biomarker for predicting possible onset of CIAKI following contrast administration.
