Abstract

Abstract Background: CXC chemokine ligand 16 (CXCL16) is both an oxidized low density lipoprotein receptor (ox-LDL) and a chemokine with a potential role in the pathogenesis of Diabetic Nephropathy (DN). Aim of Study: The aim of this work is to evaluate the relationship between serum CXCL16 levels and (DN) in type 2 Egyptian diabetic patients. Methods: This case-controlled study was conducted on 80 T2DM patients (group A1: 24 patients with normoalbu-minuria; group A2: 28 patients with microalbuminuria, and group A3: 28 patients with macroalbuminuria) and 20 age-and sex-matched healthy controls. All were subjected to a complete clinical evaluation and laboratory investigations which included quantitative measurements of urinary albu-min/creatinine ratio and serum CXCL16 levels by enzyme-linked immunosorbent assays. Results: Serum CXCL16 levels were significantly higher in all T2DM groups compared with healthy controls. There was a positive correlation between CXCL16, creatinine and ACR (r=0.48, p:0.039 and r=0.53, p:0.019, respectively), whereas it was significantly negatively associated to eGFR (r=–0.46, p:0.05). Regression analysis indicated that CXCL16 levels were continued significantly correlated with creatinine, eGFR and ACR (p:<0.05, for all). Conclusion: Egyptian type 2 DM patients are characterized by increased serum CXCL16 levels. There was a statistically significant correlation between CXCL16 levels and conven-tional renal markers reflecting disease progression.
