Objective. To determine the phenotypic manifestations of essential arterial hypertension (EAH) according to the vitamin D receptor gene polymorphism (VDR rs10735810, rs2228570).Material and methods. The case-control study involved 100 patients with EAH stage II, 1-3 degrees of blood pressure (BP), high and very high cardiovascular risk, 21% (21) men, 79% (79) women. The mean age of patients was 59.86 ± 6.22 y.o. The control group consisted of 60 healthy individuals, comparable in age and gender. To study the VDR gene polymorphism (rs10735810, rs2228570) performed a qualitative polymerase chain reaction in real-time. Results. Almost half of the patients with elevated normal BP (44.4%) and 34% of patients with EAH 2-3 d. there is concomitant diabetes mellitus (DM) type 2, while for EAH 1 d. it is only 19%. Obesity of 1-3 degrees was shown in 53% of patients with EAH: average EAH of 1 d. - 21%, among the EAH 2-3 d. - 25%. In the control group, 16% suffered from obesity. The distribution of VDR gene polymorphism genotypes according to the presence of DM showed that it was present in 35% of patients with AA-genotype, which is 1.6 times more often than in patients with GG-genotype (22%). Most smokers among patients with GG-genotype (26%), which is twice as common as those with AA- and AG-genotype (13% and 14%, respectively). Obesity of 1-3 degrees most often met among carriers of GG-genotype - 74%, and in the control group 14%. An elevated level of waist-hip ratio (WHR) among women with EAH was in 80% of the AA-genotype carriers, in the control group, all women had normal values. In 76% of the AG-genotype carriers and in 81% of the GG-genotype carriers, the WHR was increased by 2.3 and 2.8 times, respectively, that in the control group. Deviations of systolic and diastolic BP according to the VDR gene polymorphic variants have not been established.Conclusions. The AA-genotype is associated with DM 2 and with elevated WHR in women; GG-genotype - with elevated BMI, especially in men.
