Aim: to study relationship between genetic disorders and features of intrarenal blood flow in patients with essential arterial hypertension (AH) of 1–2 degree. Materials and methods. We examined 100 patients (60 women, 40 men) aged 35 to 58 years with 1–2‑degree essential arterial hypertension (AH) and chronic kidney disease (CKD) stages I–III. Examination included triplex scanning of renal arteries on the ultrasound scanner Vivid-7 Dimension, genotyping of single-nucleotide polymorphism А1166С of the AGTR1 gene by real time polymerase chain reaction (PCR), estimation of glomerular filtration rate (GFR) using CKD-EPI formula. Patients were divided into 2 groups: group 1 included persons with I and II stage CKD (n=65, 25 men and 40 women), group 2 included patients with stages IIIA and IIIB CKD (n=35, 15 men and 20 women). Results. Among patients of group 1 prevailed genotype AA, while among group 2 patients prevailed genotype AC. Speed of blood flow in interlobar renal arteries was higher in the group 1 compared with group 2, while in the group 2 time of acceleration of blood flow was higher than in the group 1. Discussion. The data obtained are indicative of the decrease of systolic, diastolic, and averaged maximal blood flow velocity and the lengthening of acceleration time in patients with higher CKD stage. Conclusions. The presence in the genotype of patients with 1–2‑degree AH of AGTR1 1166С allele may be considered a risk factor of early development of CKD. Lowering of speed characteristics of blood flow and lengthening of the acceleration time in patients with AH can be a criterion of hypertensive nephropathy development.

Aim. To study the frequency of polymorphic gene variants encoding proteins of renin-angiotensin system [AGT Thr174Met (rs 4762), AGT Met235Thr (rs699), AGTR1 A1166C (rs5186)], endothelial factors [NOS3 C786T (rs2070744)], and folate cycle enzymes [MTHFR C677T (rs1801133)] in patients with various ischemic stroke severity. Methods. 98 patients with ischemic stroke verified by magnetic resonance imaging and computed tomography scan of the brain, were examined. The severity of stroke was assessed by National Institutes of Health Stroke Scale. The allelic variants of genes were typified by polymerase chain reaction with the detection of amplification products in the «real time» mode. Results. The analysis of genetic polymorphism frequency of renin-angiotensin system did not reveal statistically significant differences in the study groups. The polymorphism of NOSC786T gene in the study was also not associated with the severity of ischemic stroke. Among the studied polymorphic variants, only the C677T polymorphism of MTHFR gene was revealed to be reliably associated with severe course of acute cerebral ischemia. Conclusion. C677T polymorphism of MTHFR gene is reliably associated with severe course of acute cerebral ischemia; carriage of 677T allele of MTHFR gene in the studied category of patients can cause an increased level of homocysteine and have an adverse effect on the course of acute cerebral ischemia.

Обследовано 33 пациента с отечной формой острого панкреатита и 32 -с деструктивной, из них у 19 развились гнойно-некротические осложнения. Повышение уровня сывороточного IgE выше 150 МЕ/мл наблюдалось в 44,6% случаев. У больных острым панкреатитом выявлено наличие ассоциативных связей повышение IgE с большей частотой развития деструктивных форм (р=0,017) и гнойно-некротических осложнений (р=0,0029).
