عنوان المقالة: Serum Neutrophil Gelatinase-Associated Lipocalin and Cystatin C are early Biomarkers of Contrast-Induced Nephropathy after Coronary Angiography in Patients with Chronic Kidney Disease
We had previously reported on serum neutrophil gelatinase-associated lipocalin (NGAL) as an earlier biomarker of contrast-induced nephropathy (CIN) than serum creatinine (SCr) in 100 patients with chronic kidney disease undergoing coronary angiography.1 We then compared serum NGAL to serum cystatin C (CysC) in the same group of patients. The SCr, estimated glomerular filtration rate, serum NGAL, and serum CysC were measured at baseline and various time points as appropriate post-procedure. The frequency of CIN was 11% (n = 11). Serum NGAL increased ≥25% from baseline at 24 hours in 7 patients with CIN (P = .04). Serum CysC increased ≥25% from baseline at 24 hours in 4 patients with CIN (P = .008). Changes in serum NGAL and serum CysC from baseline at 24 hours (▵ values) could diagnose CIN 24 hours earlier than SCr with serum NGAL showing a superior performance.
