Item The relationships of IRS-1 polymorphism with hemodynamic disorders in hypertensive patients depending on body weight and metabolic comorbidity(Aluna Publishing, 2022) Псарьова, Валентина Григорівна; Псарева, Валентина Григорьевна; Psarova, Valentyna Hryhorivna; Kochuieva, M.; Gogunska, I.; Shchur, O.; Kochuiev, G.; Tymchenko, H.The aim: The aim was to study the relationships of IRS-1 gene polymorphism with indicators of the structural and functional state of the heart and blood vessels in patients with arterial hypertension under conditions of different metabolic comorbidity and body weight. Materials and methods: We examined 340 patients with arterial hypertension with different body weight and different types of metabolic comorbidity and 30 healthy individuals aged 45-55. Anthropometric, Biochemical, Molecular genetic methods, Instrumental, Statistical methods were used. Results: The presence of G/R + R/R genotypes in hypertensive patients with normal body weight was associated with an increase in intima-media thickness (CIMT), pulse wave velocity of carotid artery (cPWV) and lower endothelium-dependent vasodilatation (EDVD) compared with G/G genotype carriers. Hypertensive patients with obesity, carriers of G/R and R/R genotypes displayed more pronounced similar changes in vascular remodeling (higher CIMT, cPWV and lower EDVD) and as well as cardiac remodeling (larger sizes and left ventricular mass (LVM)) compared with G/G genotype carriers. Overweight carriers of the G/R + R/R genotypes were characterized by enlargement of LVM and its sizes, a higher CIMT indicator, but this effect was less than in the comorbidity of hypertension and obesity. In hypertensive patients with hypertension, obesity and type 2 diabetes mellitus, the presence of G/R + R/R genotypes was associated with an increase in left ventricular size, left ventricular mass index (LVMI) and CIMT. Conclusions: The relationships of IRS-1 polymorphism with indicators of cardiovascular remodeling in hypertensive patients depending on body weight and the presence of various metabolic comorbidity have been established.Item Influence of physical activity on the effectiveness of various antihypertensive therapy in obese hypertensive patients(Scientific Publishing Center «InterConf», 2021) Псарьова, Валентина Григорівна; Псарева, Валентина Григорьевна; Psarova, Valentyna Hryhorivna; Kochuieva, M.; Моісеєнко, Ірина Олегівна; Моисеенко, Ирина Олеговна; Moiseyenko, Iryna OlehivnaPhysical activity is an important factor in improving the dynamics of treatment in patients with AH with obesity in different drug therapy regimens.Item Hemodynamic and metabolic disorders in obese patients with resistant hypertension(Oxford University Press, 2020) Shalimova, A.; Псарьова, Валентина Григорівна; Псарева, Валентина Григорьевна; Psarova, Valentyna Hryhorivna; Kochuieva, M.; Kolesnikova, O.; Isaieva, A.; Prosolenko, K.Patients with resistant hypertension differed from hypertensive obese patients without resistance with higher BMI and BP, higher levels of triglycerides, insulin, HbA1c, more pronounced IR, cardiovascular remodeling, imbalance of oxidative stress - antioxidant protection system, higher proinflammatory and RAAS activity. Patients with true resistance differed from pseudo-resistant patients with significantly lower BMI, higher aldosterone levels, more pronounced imbalance of the system of oxidative stress - antioxidant protection and less pronounced adipokines imbalance.Item Features of metabolic and hemodynamic indicators in obese patients with resistant hypertension(Wolters Kluwer Health, 2021) Shalimova, A.; Псарьова, Валентина Григорівна; Псарева, Валентина Григорьевна; Psarova, Valentyna Hryhorivna; Kochuieva, M.Objective: To establish the features of metabolic and hemodynamic parameters in obese patients with true and pseudo-resistant arterial hypertension (AH).Item The Role of Genetic Polymorphism in the Formation of Arterial Hypertension, Type 2 Diabetes and their Comorbidity(Current Pharmaceutical Design, 2019) Shalimova, A.; Fadieienko, G.; Kolesnikova, O.; Isayeva, A.; Zlatkina, V.; Nemtsova, V.; Prosolenko, K.; Псарьова, Валентина Григорівна; Псарева, Валентина Григорьевна; Psarova, Valentyna Hryhorivna; Kyrichenko, N.; Kochuieva, M.Background: Hereditary component plays a significant role in the formation of insulin resistance (IR) - one of the pathogenetic links of arterial hypertension (AH) and type 2 diabetes mellitus (DM2). However, the genetic predisposition to IR can not be realized and does not manifest itself clinically in the absence of appropriate factors of the environment (excessive nutrition, low physical activity, etc.). Objective: The review summarizes the results of studies which describe the contribution of genetic polymorphism to the formation and progression of AH, DM2 and their comorbidity in various populations. Results: In many studies, it has been established that genetic polymorphism of candidate genes is influenced by the formation, course and complication of AH and DM2. According to research data, the modulating effect of polymorphism of some genetic markers of AH and DM2 on metabolism and hemodynamics has been established. The results of numerous studies have shown a higher frequency of occurrence of AH and DM2, as well as their more severe course with adverse genetic polymorphisms. At the same time, the role of genetic polymorphism in the formation of AH and DM2 differs in different populations. Conclusion: Contradictory data on the influence of gene polymorphisms on the formation of AH and DM2 in different populations, as well as a small number of studies on the combined effects of several polymorphisms on the formation of comorbidity, determine the continuation of research in this direction.Item Features of hemodynamic and metabolic disorders in obese patients with resistant hypertension(Medical Information Department, 2020) Shalimova, A.; Псарьова, Валентина Григорівна; Псарева, Валентина Григорьевна; Psarova, Valentyna Hryhorivna; Kochuieva, M.; Kolesnikova, O.; Isaieva, A.; Zlatkina, V.; Nemtsova, V.The aim was to establish the features of hemodynamic and metabolic parameters in obese patients with true and pseudo-resistant arterial hypertension (AH). Material and methods. The study included 200 patients with uncontrolled AH and obesity. Patients were initially prescribed dual antihypertensive therapy. Those patients who did not reach target blood pressure (BP) levels after 3 months on dual therapy were additionally prescribed a third antihypertensive drug. Of the 98 patients who were assigned to triple therapy, 48 patients did not reach target BP (27 patients had pseudo-resistant and 21 patients had true resistant AH). These patients were additionally prescribed a fourth antihypertensive drug (spironolactone). The effectiveness of the treatment was evaluated 6 months after the start of antihypertensive therapy. Results. After 6 months of therapy, unlike patients without resistance, individuals with resistant AH had more pronounced cardiovascular remodeling and metabolic disorders, disbalance of oxidative stress-antioxidant protection, proinflammatory activity and higher activity of the renin-angiotensin-aldosterone system. Patients with true resistance differed from pseudo-resistant patients by having significantly lower body mass index (BMI); in the absence of differences in BP levels, cardiovascular remodeling, lipid and carbohydrate profiles, patients with true resistance had significantly higher levels of aldosterone, higher activity of oxidative stress system, lower levels of general antioxidant protection, higher adiponectin levels, and lower leptin level. Conclusions. Obese patients with true resistance differed from pseudo-resistant patients by having significantly lower BMI, higher aldosterone levels, more pronounced imbalance of the system of oxidative stress-antioxidant protection and less pronounced adipokine imbalance.Item Features of the Severity of Cardiovascular Remodeling and Metabolic Disorders in Hypertensive Patients with Obesity in the Presence of Two Unfavorable Genotypes of the ADIPOQ and IRS-1 Genes(Endocrine Society, 2020) Shalimova, A.; Псарьова, Валентина Григорівна; Псарева, Валентина Григорьевна; Psarova, Valentyna Hryhorivna; Kyrychenko, N.; Kochuieva, M.The results of a number of studies have shown that in arterial hypertension (AH), G/T and T/T genotypes of the adiponectin gene (ADIPOQ) and Gly/Arg and Arg/Arg genotypes of the insulin receptor substrate 1 gene (IRS-1) are associated with a greater severity of metabolic disorders and hemodynamic parameters compared with G/G and Gly/Gly genotypes of these genes. The aim of the study: to evaluate the severity of cardiovascular remodeling and metabolic disorders in hypertensive obese patients in the simultaneous presence of two unfavorable genotypes of the ADIPOQ and IRS-1 genes. Methods: We examined 300 AH patients: 200 patients with AH and obesity, 50 patients with AH and normal body weight, 50 patients with AH and overweight, 40 patients with AH, obesity and type 2 diabetes mellitus (DM2), 30 healthy individuals. The polymorphisms of the ADIPOQ and IRS-1 was assessed by molecular genetic method. Results: It was found that in all groups of hypertensive patients, regardless of body weight and the presence of DM2, the simultaneous presence of two unfavorable genotypes of the ADIPOQ and IRS-1 genes occurred significantly more often than in healthy individuals: in 41% of AH patients with obesity, 30% of AH patients with normal weight, 40% of AH with overweight, 57.5% of AH with obesity and DM2 vs. 13.3% of healthy individuals. In hypertensive patients, in the presence of overweight and obesity, the frequency of combination of the two unfavorable genotypes of these genes was significantly higher than in AH patients with normal body weight. Conducting comparative evaluation of AH patients with obesity depending on the presence of two unfavorable genotypes or two protective genotypes of the ADIPOQ and IRS-1 genes showed that carriers of the combination of the G/T + T/T genotype of the ADIPOQ and the Gly/Arg + Arg/Arg genotype of the IRS-1 had a higher body mass index, more pronounced insulin resistance, cardiovascular remodeling, adipokine imbalance, impaired carbohydrate and lipid metabolism. Conclusions: In AH patients, the frequency of the simultaneous presence of two unfavorable polymorphisms of ADIPOQ and IRS-1 genes was higher than in healthy individuals. In AH patients with overweight and obesity, the frequency of combination of the two unfavorable genotypes of the ADIPOQ and IRS-1 genes was significantly higher than in normal body weight. The presence of a combination of two unfavorable genotypes of the ADIPOQ and IRS-1 genes in patients with AH and obesity was associated with a greater severity of cardiovascular remodeling and metabolic disorders compared with the combination of two protective genotypes of these genes.Item Associations of IRS-1 polymorphism with various components of the metabolic syndrome in hypertensive patients(ALUNA Publishing, 2019) Kochuieva, M.; Псарьова, Валентина Григорівна; Псарева, Валентина Григорьевна; Psarova, Valentyna Hryhorivna; Ruban, L.; Кириченко, Наталія Миколаївна; Кириченко, Наталия Николаевна; Kyrychenko, Nataliia Mykolaivna; Alypova, O.; Matlai, Olha Ivanivna; Shalimova, A.; Матлай, Ольга Іванівна; Матлай, Ольга ИвановнаIntroduction: The metabolic syndrome is one of the most discussed cross-disciplinary problems of modern medicine. Now there are various definitions and criteria of diagnostics of metabolic syndrome. The abdominal obesity is considered the main component of the metabolic syndrome, as a reflection of visceral obesity which degree is offered to be estimated on an indirect indicator – a waist circumference. Alongside with abdominal obesity, a number of classifications distinguish insulin resistance (IR) as a diagnostic criterion of metabolic syndrome. It is proved that IR is one of the pathophysiological mechanisms influencing the development and the course of arterial hypertension (AH), type 2 DM and obesity. There are two components in the development of IR: genetic (hereditary) and acquired. In spite of the fact that IR has the accurate genetic predisposition, exact genetic disorders of its appearance have not been identified yet, thus demonstrating its polygenic nature. The aim: To establish possible associations of the insulin receptor substrate-1 (IRS-1) gene polymorphism with the severity of the metabolic syndrome components in patients with arterial hypertension (AH). Materials and methods: 187 patients with AH aged 45-55 years and 30 healthy individuals. Methods: anthropometry, reactive hyperemia, color Doppler mapping, biochemical blood analysis, HOMA-insulin resistance (IR), glucose tolerance test, enzyme immunoassay, molecular genetic method. Results: Among hypertensive patients, 103 had abdominal obesity, 43 - type 2 diabetes, 131 - increased blood triglycerides, 19 - decreased high density lipoproteins, 59 - prediabetes (33 - fasting hyperglycemia and 26 - impaired glucose tolerance), 126 had IR. At the same time, hypertensive patients had the following distribution of IRS-1 genotypes: Gly/Gly - 47.9%, Gly/Arg - 42.2% and Arg/Arg - 10.7%, whereas in healthy individuals the distribution of genotypes was significantly different: Gly/Gly - 86.8% (p<0.01), Gly/ Arg - 9.9% (p<0.01) and Arg/Arg - 3.3% (p<0.05). Hypertensive patients with Arg/Arg and Gly/Arg genotypes had significantly higher HOMA-IR (p<0.01), glucose, insulin and triglycerides levels (p<0.05), than in Gly/Gly genotype. At the same time, body mass index, waist circumference, blood pressure, adiponectin, HDL, interleukin-6, C-reactive protein, degree of endothelium-dependent vasodilation, as well as the frequency of occurrence of impaired glucose tolerance did not significantly differ in IRS-1 genotypes. Conclusions: in hypertensive patients, the genetic polymorphism of IRS-1 gene is associated with such components of the metabolic syndrome as hypertriglyceridemia and fasting hyperglycemia; it is not associated with proinflammatory state, endothelial dysfunction, dysglycemia, an increase in waist circumference and decrease in HDL.
