AIM: Visfatin is an adipocytokine that has recently generated much interest. The aim of the study was to assess visfatin in correlation with markers of endothelial damage and inflammation in haemodialyzed and peritoneally dialyzed patients. METHODS: Visfatin, leptin, apelin and adiponectin, markers of coagulation (thrombin-antithrombin complexes (TAT), prothrombin fragments 1+2 (F1+2)), fibrinolysis (tissue plasminogen activator (tPA), plasminogen activator inhibitor type 1 (PAI-1)), endothelial function/injury (Von Willebrand factor (vWF), thrombomodulin, intracellular adhesion molecule (ICAM), vascular cell adhesion molecule (VCAM), CD146) and inflammation (high-sensitivity C-reactive protein (hsCRP), tumour necrosis factor-alpha (TNF-alpha) and interleukin (IL)-6) were assessed. RESULTS: Triglycerides, hsCRP, creatinine, IL-6, TNF-alpha, vWF, F1+2, TAT, thrombomodulin, ICAM, VCAM, CD146, PAI-1, leptin, adiponectin and visfatin were elevated in dialyzed patients over controls. Visfatin correlated significantly, in univariate analysis, in haemodialyzed patients with markers of endothelial damage/inflammation (CD146, ICAM, IL-6), other adipocytokines, Kt/V and dialysis vintage, and tended to correlate with hsCRP. In peritoneally dialyzed patients, visfatin correlated significantly with haemoglobin, and markers of endothelial damage. In the healthy volunteers visfatin correlated significantly with ICAM, creatinine and IL-6. In multiple regression analysis in HD patients visfatin was only independently related to Kt/V, dialysis vintage and IL-6. CONCLUSION: Elevated visfatin related to markers of inflammation might represent a novel link between inflammation and adipocytokines in dialyzed patients. Time on dialyses and dialysis adequacy may influence visfatin in dialyzed patients due to the decreased clearance of visfatin.
