Soluble intracellular adhesion molecule-1 and omentin-1 as potential biomarkers of subclinical atherosclerosis in hemodialysis patients

Purpose. Atherosclerotic cardiovascular complications represent significant cause of mortality in hemodialysis (HD) patients. The aims of this study were to: (a) investigate association of sICAM-1, sVCAM-1, omentin-1 and other non-traditional risk factors with subclinical atherosclerosis ; (b) examine the diagnostic value of these specific markers in the early detection of subclinical atherosclerosis ; and (c) examine their role as predictors of mortality in group of patients with subclinical atherosclerosis on regular HD. Materials and methods. Starting from November 2011, a cohort of 210 HD patients participated in this 3-year follow-up study. The subjects were divided into three groups according to the presence of atherosclerosis. Atherosclerotic disease was assessed by measuring carotid intima-media thickness (IMT). Samplings were withdrawn at baseline and thereafter every 12 months until the end of follow-up. Results. IMT showed weak correlation with sICAM-1 (r = 0.39, P = 0.001), sVCAM-1 (r = 0.27, P = 0.015) and omentin-1 (r = −0.25, P = 0.020), and also omentin-1 showed good correlation with parameters of systolic and diastolic function (r = 0.52, P = 0.001 and r = 0.51, P = 0.001). Multivariate analysis showed that sICAM-1 and sVCAM-1 concentrations were a strong independent correlate of IMT (P = 0.031 and P = 0.010, respectively). The Cox proportional analysis showed that sICAM-1 and omentin-1 concentrations were strong predictors of cardiovascular death (HR 1.85, CI 1.18–2.32, P = 0.021 and HR 4.14, CI 1.38–12.1, P = 0.004, respectively) and that serial measurements of these markers predict IMT progression (HR 1.98, 95% CI 1.21–2.38, P < 0.002 and HR 2.91, 95% CI 1.57–4.72, P < 0.001, respectively). Conclusions. Our study demonstrated that sICAM-1 and omentin-1 levels are strong predictors of cardiovascular death in HD patients with subclinical atherosclerosis.
