Abstract
Cell adhesion molecules play a rather important role in the development of atherosclerosis mediating the attachment of monocytes to the endothelium. It has also been well established that hyperlipidemia is a risk factor for atherosclerosis from childhood. The aim of this study was to investigate whether the soluble adhesion molecules correlate with the circulating lipid levels in children. The study population consisted of 107 children (64 boys, 43 girls) aged 6-13 y. Parental history of cardiovascular disease, age, gender, and anthropometric parameters were recorded in all children. Blood samples were obtained from every child following a 12-hour fasting period. Serum triglycerides, total cholesterol, and its fractions as well as plasma levels of P and E selectins and adhesion molecules sVCAM-1 and sICAM-1 were determined. After controlling for age and body mass index, both sVCAM-1 and sP-selectin levels were inversely associated with HDL values (r = −0.33, p = 0.005 and r = −0.39, p = 0.001, respectively). A significant positive correlation was found between sVCAM-1 and triglycerides (r = 0.48, p < 0.001). An increment of 10 mg/dL of HDL corresponds to about 50% reduction of the odds for endothelial dysfunction whereas an increment of 10 mg/dL of triglyceride levels indicates a more than 3-fold excess risk, using either sP-selectin or sVCAM-1 levels as a surrogate for the determination of endothelial dysfunction. We suggest that HDL-C and triglycerides correlate in a biologically plausible way with soluble adhesion molecules, which therefore could be considered as useful indicators of the process of preclinical atherosclerosis even from childhood.
