The aim of the study. To study the dependence of expression of vascular endothelial growth factor (VEGF) and endothelial cell desquamation intensity in patients with the metabolic syndrome (MS) according to the body mass index and dependence of levels of thyroid hormones on the level of VEGF and content of desquamated endothelial cells in venous blood serum.

Methods. We have determined the level of VEGF and desquamated endothelial cells in the serum of venous blood in 68 patients with MS (48 obese and 20 non-obese patients), and indicators reflecting the metabolism of thyroid hormones namely thyroid stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), thyroid-stimulating hormone/free triiodothyronine ratio (TSH/fT3),  thyroid stimulating hormone/free thyroxine ratio (TSH/FT4 ), thyroid index (TI), the total thyroid index (TTI), free triiodothyronine/free thyroxine ratio  (fT3/fT4).

Results. Expression of VEGF as well as the number of desquamated endothelial cells in venous blood serum increased significantly with enhancement of the degree of obesity. Desquamated endothelial cells correlated positively with  TSH,  TSH/fT3, TSH/fT4 (p <0.05) and negatively with thyroid index, fT3/fT4 (p <0.05). Also we found a positive correlation between the expression of VEGF and TSH, fT4, TSH/fT3, TSH/fT4 (p <0.05) and negative with T3, fT3/fT4 and TTI (p<0.05).

Conclusions. Expressoin of vascular endothelial growth factor and endothelial cell desquamation enhances with increasing of the degree of obesity, which are associated with the level of thyroid hormones metabolism and the functioning of the pituitary-thyroid axis.
