Abstract

Background: Obesity in children increases the risk of atherosclerosis. Endothelial dysfunction is an important factor in the pathogenesis of atherosclerosis, and endothelial microparticles (EMPs) are considered as markers of endothelial dysfunction. In this study, we aimed to evaluate circulating EMPs in obese and overweight children and to disclose the measure of obesity with the strongest relation with circulating microparticles and carotid atherosclerosis.

Methods: This prospective study included 55 obese and overweight children and 23 healthy controls. Insulin resistance was studied. Both in vivo and in vitro human umbilical vein endothelial cell evaluations were used for the study. Circulating EMPs (CD144 and CD146) were measured by flow cytometry. The carotid artery intima-media thickness (cIMT) and left ventricular mass index (LVMI) were measured using ultrasound and echocardiography, respectively. Study groups were compared for anthropometric measurement, insulin resistance, circulating EMP, cIMT, and LVMI. The relationship among overweight, obesity, and circulating EMPs were investigated.

Results: Blood pressure, CD144+EMP levels, and LVMI were statistically higher in the patients group than in the control group. The multiple logistic regression analysis and the backward elimination method showed that CD144+EMP and systolic blood pressure had a linear relationship with overweight and obesity.

Conclusion: Our results suggest that endothelial damage starts in the early stage of childhood obesity and that obese and overweight children have increased circulating CD144+EMPs, showing that endothelial dysfunction and increased CD144+EMPs may be related to obesity.
