Combined hyperlipidemia (coincident present hypercholesterolemia and hypertriglyceridemia) may contribute to the development of atherosclerosis and coronary artery disease by increasing of cell adhesion molecules (CAMs). Although the cellular expression of CAMs is difficult to assess clinically, soluble forms of CAMs (sCAMs) are present in the circulation and may serve as marker of CAMs. The aim of this study was to determine whether combined hyperlipidemia in overweight adults without clinical evidence of cardiovascular disease, diabetes mellitus or hypertension is associated with increased expression of CAMs. We examined the levels of soluble cell adhesion molecules (sICAM-1, sE-Selectin and sP-Selectin) in blood plasma of overweight adults (n = 36), mean of BMI 27.08 +/- 4.12 kg/m2 with combined hyperlipidemia, with total cholesterol (TC) 7.27 +/- 1.50 mmol/l, LDL cholesterol 4.89 +/- 1.35 mmol/l, HDL cholesterol 1.27 +/- 0.51 mmol/l and triglycerides (TG) 4.08 +/- 2.22 mmol/l before lipid-lowering therapies, and in equal numbers of age, sex and BMI matched controls. Patients with combined hyperlipidemia had significantly higher plasma levels of soluble intercellular adhesion molecule-1 (sICAM-1) (298.13 +/- 41.24 ng/ml versus 241.35 +/- 37.48 ng/ml; P < 0.001), sE-Selectin (63.31 +/- 9.48 ng/ml versus 42.16 +/- 14.18 ng/ml; P < 0.001) and sP-Selectin (161.18 +/- 20.85 ng/ml versus 111.54 +/- 26.12 ng/ml; P < 0.001) compared with overweight, non-hyperlipidemic control subjects. Combined hyperlipidemia in adults with overweight is associated with elevated soluble plasma levels of CAMs. We suppose that levels of CAMs in these patients may be determined as a marker for appreciation of their potential atherosclerotic burden.
