The plasma levels of soluble intercellular cell adhesion molecule-1 (s-ICAM-1) and soluble vascular cell adhesion molecule-1 (s-VCAM-1) were assessed in clinically asymptomatic subjects to compare them between normolipidemic and various dyslipidemic phenotypes. The associations between soluble cell adhesion molecules (s-CAMs) and risk factors for atherosclerosis, markers of insulin resistance, and the intima-media thickness of the common carotid artery (IMT) were evaluated, too.Thwo hundred and thirty-four asymptomatic subjects were divided into four dyslipidemic phenotypes (DLP) according to apolipoprotein B (apoB) and triglycerides (TG): DLP1 (N.=58, apoB<1.2 g/L and TG<1.5 mmol/L), DLP2 (N.=47, apoB<1.2 g/L and TG≥1.5 mmol/L), DLP3 (N.=31, apoB≥1.2 g/L and TG<1.5 mmol/L) and DLP4 (N.=98, apoB≥1.2 g/L and TG≥1.5 mmol/L). DLP1 (normo-apoB /normo-TG) served as a control group.A significant difference in s-ICAM-1 between DLP1 (502.0 [457.1-568.2] ng/mL) and DLP4 (567.9 [502.8-692.1] ng/mL, P<0.001) was found. No significant differences in s-VCAM-1 between DLPs were apparent. S-ICAM-1 was independently predicted by HDL-cholesterol, non-HDL-cholesterol, proinsulin, C-peptide, waist, systolic and diastolic blood pressure. S-VCAM-1 was predicted only by age and systolic blood pressure. Both s-CAMs were detected as independent predictors for IMT, which was significantly increased in DLP 4.The elevation of s-ICAM-1 was presented only in patients with simultaneously elevated TG and apoB (DLP4) in comparison with normolipidemic subjects. Patients with DLP 4 had significantly increased IMT, which was independently predicted by levels of s-ICAM-1 and of s-VCAM-1. These findings pointed out DLP4 subjects as individuals with the highest risk for early manifestation of atherosclerosis.
