IL-18, VCAM-1 and P-selectin as early biomarkers in normoalbuminuric Type 2 diabetes patients

Abstract

Aim: To investigate the pathophysiological role of different biomarkers in diabetic kidney disease (DKD) among normoalbuminuric patients with a low-estimated glomerular filtration rate (eGFR). Methods: In this cross-sectional study of 200 normoalbuminuric Type 2 diabetes patients, 28 patients (14%) had a low eGFR. Results: The IL-18, VCAM-1 and P-selectin levels were significantly higher at a low eGFR. On analyzing the area under the receiver operating characteristic curve, these biomarkers had significant diagnostic value and have important pathophysiological role in the progression of DKD. Conclusion: Among normoalbuminuric Type 2 diabetes patients, IL-18, VCAM-1 and P-selectin may play a significant role in the prediction of early DKD. Further prospective studies need to be conducted to confirm this observation.
