Objective:Hypertension and dyslipidemia represent two of the most relevant modifiable cardiovascular risk factors and they often coexist. The aim of the research was to study lipid disorders and essential arterial hypertension (EAH) risk depending on AGTR1 (rs5186) and VDR (rs2228570) genes polymorphism.Design and method:100 subjects with EAH and target-organ damaging (2nd stage), moderate, high or very high cardiovascular risk were involved in the case-control study. Among them, 70,83% females and 29,17% males, mean age 57,86 ± 7,81y.o. Control group consisted of 60 practically healthy individuals of relevant age. The lipid panel parameters, such as: TC (Total cholesterol), TG (Triglycerides), LDL-C (Low-density lipoprotein cholesterol), HDL-C (High-density lipoprotein cholesterol) were investigated in blood plasma, using diagnostic kits “Accent 200” (Poland). The atherogenic index (IA) was calculated by the formula: (TC – HDL-C)/ HDL-C. Gene polymorphism of AGTR1 (rs5186) and VDR (rs2228570), was detected by polymerase chain reaction (PCR).Results:Decreased HDL-C is associated with 2nd and 3d degrees of EAH (p = 0,048). The risk of EAH increases in C-allele carriers of AGTR1 (rs5186) gene with hypercholesterolemia (TC> 5,0mmol/l) 1,5 times (OR–2,50;p = 0,048), with an increase in LDL-C and IA – 1,58 and 2,12 times (OR–10,80;p = 0,019), respectively. Homozygous carriers of the minor A-allele had extremely higher concentrations of TC, atherogenic LDL-C and IA, than GG-carriers – by 9,29%, 11,11% and 12,80% (pAA<0,05), respectively. Risk of EAH increases with hypertriglycerolemia 1,89 times (OR–2,93;p = 0,03) and with the increase in LDL-C – 1,26 times (OR–3,60;p = 0,038) in AA-genotype carriers of VDR (rs2228570) gene. Risk of EAH synergistically escalates almost twice in A-allele carriers of VDR (rs2228570) gene with a decrease of HDL-C (OR–2,88;p = 0,046) and the increase of IA (OR–2,70;p = 0,039), significantly only in AG-carriers though. ANOVA analysis confirmed the association of VDR (rs2228570) gene with the increase in IA (F = 3,80;p = 0,05).Conclusions: The EAH risk escalates with hypercholesterolemia, elevated both LDL-C and IA in C-allele carriers of AGTR1 (rs5186) gene, as well as with decreased HDL-C and increased IA in A-allele carriers VDR (rs2228570) in the observed.

Essential arterial hypertension (EAH) is a polygenic disease due to environmental, genetic, and epigenomic factors. The study aimed to establish the association of single nucleotide polymorphism (SNP) of AGTR1 (rs5186) and VDR (rs2228570) genes with the blood pressure (BP) elevation in EAH patients. 100 EAH subjects with hypertensive-mediated organ damaging (2nd stage), moderate, high, or very high cardiovascular risk were recruited into the case-control study. There were 70.83% females and 29.17% males, mean age 57.86±7.81 y.o. The control group included 60 healthy individuals of relevant age and gender distribution. Estimation of AGTR1 (rs5186) and VDR (rs2228570) gene polymorphism was performed by Real-Time Polymerase Chain Reaction. In EAH patients, the AGTR1 gene (rs5186) mutation occurs with a frequency of 2.78% in the absence of such among healthy individuals. The VDR (rs2228570) gene mutation occurs with a frequency of 23% cases. The C-allele carriers’ (AGTR1 gene) numbers with 2nd and 3rd BP values degree dominate over AA-genotype patients by 25.32% (χ2=4.52; р=0.033). VDR gene (rs2228570) polymorphic variants do not link to BP elevation values. Thus, the C-allele of the AGTR1 gene (rs5186) is associated with BP elevation in hypertensive patients. BP values do not depend on VDR gene (rs2228570) polymorphic variants.

Objective:Essential arterial hypertension (EAH) remains the most common global non-communicable disease. More than 50% of patients with hypertension have additional cardiovascular risk factors. The aim of this study is to establish the role of 25-hydroxyvitamin D as an additional risk factor of EAH depending on 1166A>C polymorphism of AGTR1 gene (rs5186) and A/G polymorphism of VDR gene (rs2228570).Design and method:100 subjects with EAH and target-organ damaging (2nd stage), moderate, high, very high cardiovascular risk were involved in the case-control study. Among them, 70.84% females, 29.16% males, mean age 57.86 ± 7.81 yo. The control group consisted of 60 healthy individuals of relevant gender and age. All recruited subjects were tested for serum levels 25-hydroxyvitamin D (immune luminescent test “MAGLUMI’’, “SNIB’’, China). To detect gene polymorphism the qualitative real-time polymerase chain reaction was done. AGTR1 gene genotyping was performed for 72 patients and 48 healthy individuals and VDR gene – for 100 patients and 60 healthy subjects.Results:EAH associates with the decreased 25-hydroxyvitamin D (<30 ng/ml) regardless the genotypes AGTR1 (rs5186) and VDR (rs2228570) genes. Reduced serum level of 25-hydroxyvitamin D escalate the risk of EAH almost threefold (OR – 2.90; 95%CI OR:1.0–8.59; p = 0.048).Conclusions:Low level of 25-hydroxyvitamin D increases the EAH risk regardless the AGTR1 (rs5186) and VDR (rs2228570) genes’ alleles in the examined population.

Objective – to analyze the association of risk factors with the 1666 A>C polymorphism of the AGTR1 gene in patients with essential hypertension.Material and methods. 100 patients were screened, 72 of whom were genotyped. The control group consisted of 48 healthy individuals who did not differ in gender and age, and with the group of patients.Results. The obtained data confirmed that the level of blood pressure elevation is associated, to some extent, with modified (diabetes mellitus 2, smoking, body mass index) and unmodified factors (family history, gender) the risk of essential hypertension. The results of the analysis of blood pressure levels considering the A1166C polymorphism of the AGTR1 gene showed that the values of systolic and diastolic blood pressure in the group of patients with C-allele carriers were higher than in carriers of AA genotype: SBP – by 5.38% (p<0.05), DBP – by 5.15% (p<0.05). Conclusions. The level of blood pressure in patients with essential hypertension depends on body mass index and smoking. In carriers of the C-allele of the AGTR1 gene (A1166C), the level of systolic and diastolic blood pressure exceeds the ones of the carriers of the AA genotype. The presence of the C-allele of the AGTR1 gene (A1166C) almost doubles the risk of severe essential hypertension [OR = 2.75; p = 0.037].
