BACKGROUND: Endothelial dysfunction (ED) is closely linked to cardiovascular disease and outcome in patients with chronic kidney disease (CKD). Visfatin is an adipocytokine that recently generated much interest; however, its role in CKD remains to be clarified. This study aimed to assess visfatin in correlation with markers of ED and inflammation in Egyptian patients with CKD. METHODS: The study included 40 non-diabetic, clinically stable CKD patients and 20 healthy volunteers. Serum levels of visfatin, markers of ED (intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1)) and markers of inflammation (interleukin-6 (IL-6), and C-reactive protein (CRP)) were measured. Endothelial function was evaluated using brachial artery flow-mediated dilatation (FMD). RESULTS: Serum visfatin, ICAM-1, VCAM-1, CRP, and IL-6 levels were significantly elevated and FMD% was decreased in CKD patients as compared to controls. Visfatin correlated positively with ICAM-1, VCAM-1, CRP, and IL-6 and negatively with FMD% in CKD patients. In a multiple regression model, visfatin was strongly and independently associated with FMD (Beta=-0.02, P<0.001) in CKD patients. CONCLUSIONS: Serum visfatin is strongly associated with endothelial adhesion molecules and FMD%, suggesting that visfatin is an important promising biomarker for prediction of ED and future cardiovascular risk in CKD patients. Moreover, the relationship between visfatin and IL-6 indicates that circulating visfatin may reflect the sub-clinical inflammatory status. Thus, visfatin might be involved in the complex interactions between ED, inflammation, and atherosclerosis and their major clinical consequences; however, further prospective studies are required to prove this hypothesis.
