| Popis: | Endothelial dysfunction has been considered in the pathogenesis of obesity widespread in the population. The purpose of this review was to provide updated information about pathogenetic features and markers of endothelial dysfunction in obese patients. We mentioned systemic disorders in obesity, such as oxidative stress, an increase in pro-inflammatory cytokines – tumor necrosis factor alpha, interleukin-6, and arginase activity. We also discussed the role of insulin resistance in the development of endothelial dysfunction, as well as the product of adipose tissue metabolism – monocyte chemoattractant protein-1. The participation of perivascular adipose tissue, hyperoxia of adipose tissue in the regulation of inflammation was considered. We illustrated the influence of atherogenic concentrations of oxidized low-density lipoproteins, the asymmetric dimethyl-L-arginine level on endothelial function. Changes in laboratory parameters were analyzed: endothelin-1, levels of microalbuminuria, homocysteine and uric acid. We also described cytological (circulating vascular cells, endothelial microparticles) and instrumental (endothelium-dependent vasodilation, peripheral arterial tonometry, intima-media complex thickness of the common carotid artery, ultrasound kidneys examination with duplex scanning of the renal arteries) methods for assessing endothelial function. Factors that influence the risk of cardiovascular complications were arterial hypertension and arterial stiffness, high levels of low-density lipoprotein and triglycerides, reduced physical activity. The determination of endothelial function in patients with obesity can be important for predicting the pathology of the cardiovascular system. Information on the assessment of markers of endothelial dysfunction in such patients may expand the possibilities of early diagnosis and prevention of cardiovascular complications. |
