Diabetic nephropathy is a common diabetic microvascular disease with a prevalence of about 10% to 42%. Research has shown that neutrophil gelatinase-associated lipocalin (NGAL) levels would increase rapidly in the urine and blood of patients with acute kidney failure. NGAL may represent an early and predictive kidney injury biomarker due to the increase of NGAL occurs earlier than that of molecules (creatinine, cystatin C and £]2-microglobulin) for traditional assessment of renal injury in renal disease samples. To evaluate the association of plasma level of NGAL and £]2-microglobulin with diabetic nephropathy, this study was performed on 21 diabetic patients without nephropathy as the control group and 21 patients with diabetic nephropathy stage 2, 26 patients with stage 3, 9 patients with stage 4 and 16 patients stage 5 as the study group. Collection of blood and measurements of all cases were approved by the ethical committee. The results indicate that the levels of blood urea nitrogen (BUN), creatinine, NGAL, and £]2-microglobulin of study group were significantly higher than control group (P<0.001), while the glomerular filtration rate (GFR) was significantly lower than the control group (P<0.001). Linear regression analysis show that NGAL was positively correlated with white blood cells, BUN, creatinine, £]2-micrglobulin and negatively correlated with GFR; and £]2-micrglobulin was positively correlated with BUN, creatinine, NGAL and negatively correlated with GFR. All results indicate that plasma NGAL levels in diabetic nephropathy were positively correlated with renal function parameters, and closely correlated with kidney injury, suggesting that NGAL may play an important role in the progression of diabetic nephropathy.
