Показники стану ендотелію у хворих на гіпертонічну хворобу та ожиріння залежно від поліморфізмів генів PPARА та PPARG

Abstract

The aim of the study was assessment of the optimization of the endothelium in hypertensive patients with obesity by identifying the gene polymorphisms piroksosomalnyh receptors (PPAR and PPARG) in combination with inflammation factors. There were examinated 352 patients with hypertension and obesity. Patients matched for age and sex. ELISA was determined the level of CRP, TNF-a, endothelin-1, nitric oxide (eNOs, NOx), IL-4, immunoreactive insulin in the serum. The gene polymorphisms of PPARA and PPARG studying by the polymerase chain reaction. The intima-media complex of common carotid artery measuring by echocardiography on the diagnostic complex «Ultrasound scanner» (USA). The obtained results indicate that patients - carriers 162Val allele gene PPAR observed more reduction endothelium-dependent vasodilation and simultaneous increase of endothelin-1 and metabolite concentration NOx, which is evidence of more severe violations of the functional state of the endothelium. If detected genotype Pro12Pro determined by the thickness of intima-media of common carotid artery, it would indicate an earlier development of atherosclerotic process. There is a significant difference between the metabolite concentrations of NOx and systemic inflammation in patients with genotypes Leu/Leu gene PPAR.
