【 摘 要 】

Background/Aims: Chronic kidney disease and, specifically, diabetic kidney disease, is among the fastest increasing causes of death worldwide. A better understanding of the factors contributing to the high mortality may help design novel monitoring and therapeutic approaches. CXCL16 is both a cholesterol receptor and a chemokine with a potential role in vascular injury and inflammation. We aimed at identifying predictors of circulating CXCL16 levels in diabetic patients with chronic kidney disease. Methods: We have now studied plasma CXCL16 in 134 European patients with diabetic kidney disease with estimated glomerular filtration rate (eGFR) categories G1-G4 and albuminuria categories A1-A3, in order to identify factors influencing plasma CXCL16 in this population. Results: Plasma CXCL16 levels were 4.0±0.9 ng/ml. Plasma CXCL16 increased with increasing eGFR category from G1 to G4 (that is, with decreasing eGFR values) and with increasing albuminuria category. Plasma CXCL16 was higher in patients with prior cardiovascular disease (4.33±1.03 vs 3.88±0.86 ng/ml; p=0.013). In multivariate analysis, eGFR and serum albumin had an independent and significant negative correlation with plasma CXCL16. Conclusion: In diabetic kidney disease patients, GFR and serum albumin independently predicted plasma CXCL16 levels.
