Influence of visceral obesity on the secretion of adipokines with epicardial adipocytes in patients with coronary heart disease.

AIM

To study adipokine-cytokine profile of epicardial adipocytes (EAT) and subcutaneous adipose tissue (SAT) in conjunction with the area of visceral adipose tissue (VAT), biochemical and clinical characteristics of patients with coronary heart disease.

MATERIALS AND METHODS

Examined 84 patients (70 men and 14 women) with coronary artery disease. In fact the presence of visceral obesity (VO) the patients were divided into two groups. Patients VO the sampling of adipocytes of EAT and SAT, with subsequent cultivation and evaluation of adipokine and provospalitelna activity. Carried out the determination of carbohydrate and lipid metabolism, adipokine and pro-inflammatory status in the blood serum.

RESULTS

It was found that adipokine-cytokine profile of adipocytes of EAT and SAT differ. Adipocytes art of the disease on the background characterized by an increase IL-1, TNF-α, leptin-adiponectin relationships and a decrease in the content of protective factors: adiponectin and anti-inflammatory cytokine IL-10. While the SAT adipocytes was characterized by a decrease in the concentration of soluble receptor for leptin and the more pronounced leptinresistance, and the increase in proinflammatory cytokines was offset by the increase in the concentration of IL-10. The presence associated with multi-vessel coronary bed lesion, multifocal atherosclerosis, insulin resistance, atherogenic dyslipidemia, an imbalance of adipokines and markers of inflammation. So the value of the square VAT determined higher concentrations of leptin, TNF-α in adipocytes and serum, lipid and carbohydrate metabolism and a lower content of soluble receptor for leptin.

CONCLUSION

Thus, the disease on the background of the status of the adipocytes of EAT characterized as a "metabolic inflammation", and may indicate the direct involvement of adipocytes in the pathogenesis of coronary artery disease, due to the formation of adipokine imbalance and the activation of proinflammatory reactions.
