Сахарный диабет 2 типа (СД2) и артериальная гипертензия (АГ) являются частыми коморбидными состояниями, при которых активация ренин-ангиотензин-альдостероновой системы (РААС) является важным патогенетическим звеном. Функциональное состояние РААС генетически детерминировано. Идентифицированы и картированы генетические полиморфизмы системы РААС, ассоциированные с развитием как СД2, так и АГ. Ассоциации полиморфных вариантов генов РААС с СД2 и АГ среди жителей Дагестана не изучались.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Изучение ассоциации наиболее актуальных полиморфных вариантов C521T и T704C гена AGT, а также A1166C гена AGTR1 с СД2 и при сочетании СД2 с АГ у жителей Дагестана.</p></sec><sec><title>МЕТОДЫ</title><p>МЕТОДЫ. Обследовано 16 больных с СД2, 59 больных с СД2 в сочетании с АГ и 51 больной с АГ, все жители Дагестана. Контрольная группа включала 47 здоровых лиц той же возрастной группы. SNP-полиморфизмы исследовали методом аллель-специфической Real-Time PCR. Исследованы полиморфизмы C521T и T704C гена AGT, а также полиморфизм A1166C гена AGTR1.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. В группе больных с сочетанием СД2 и АГ генотип СТ полиморфизма C521T гена AGT встречался реже по сравнению с контролем (23% против 43%; χ2=3,868; р=0,049), показатель ОШ – 0,4 (0,2–0,9). Аналогично обстояло дело и с генотипом ТС полиморфизма T704C гена AGT (39% против 61%; χ2=4,282; р=0,039). ОШ составило 0,4 (0,2–0,8). Напротив, у этих же больных, но носителей гомозиготного генотипа СС полиморфизма T704C гена AGT ОШ превысило единицу и составило 2,5 (1,02–5,9), частота встречаемости 42% против 23% (χ2=3,363, р=0,05). Частота встречаемости мутантного аллеля С полиморфизма A1166C гена AGTR1 у больных только с АГ составила 31% против 14% (χ2=5,496, р=0,019, ОШ 2,5 (1,2–5,0)). Частота встречаемости дикого аллеля А у этих же больных составила 69% против 84% (χ2 =5,496, р=0,019, ОШ 0,4 (0,2–0,8)). Аналогичная ситуация определялась и с генотипом АА (52% против 73%, χ2=3,609, р=0,05), ОШ 0,4 (0,1-0,9).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. Ассоциация полиморфизмов C521T и T704C, а также A1166C генов-кандидатов AGT и AGTR1 с СД2 и АГ является важной составляющей при оценке предрасположенности к развитию этих заболеваний у жителей Дагестана.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: Type 2 diabetes and arterial hypertension are frequent comorbidities under which activation the renin-angiotensin-aldosterone system is important pathogenetic link. The functional state of the RAAS is genetically determined. Genetic polymorphisms of the RAAS system associated with the development of both type 2 diabetes and arterial hypertension have been identified and mapped. Associations of polymorphic variants of the RAAS genes with type 2 diabetes and arterial hypertension among the inhabitants of Dagestan have not been studied.</p></sec><sec><title>AIM</title><p>AIM: Studying the association of the most relevant polymorphic variants of the C521T and T704C AGT gene, as well as the A1166C AGTR1 gene with type 2 diabetes and when combining type 2 diabetes with arterial hypertension among Dagestan inhabitants.</p></sec><sec><title>METHODS</title><p>METHODS: We examined 16 patients with type 2 diabetes, 59 patients with type 2 diabetes combined with arterial hypertension and 51 patients with arterial hypertension, all residents of Dagestan. The control group included 47 healthy persons of the same age group. SNP polymorphisms were investigated by the method of allele-specific Real-Time PCR. The C521T and T704C polymorphisms of the AGT gene and the A1166C polymorphism of the AGTR1 gene were studied.</p></sec><sec><title>RESULTS</title><p>RESULTS: In the group of patients with a combination type 2 diabetes with arterial hypertension, the genotype CT of the C521T polymorphism of the AGT gene is less common compared to the control (23% vs. 43%, χ2 = 3,868, p = 0,049), OR score – 0,4 (0,2-0,9 ). The situation is similar with the TC genotype of the T704C polymorphism of the AGT gene (39% versus 61%, χ2 = 4,282, p = 0,039). OR was 0,4 (0,2–0,8).On the contrary, in the same patients, but the carriers of the homozygous CC genotype of the T704C polymorphism of the AGT gene, OR exceeded one and made 2.5 (1.02-5.9), the frequency of occurrence was 42% vs. 23%, χ2 = 3,363, p = 0,05. The frequency of the mutant allele C of the A1166C polymorphism of the AGTR1 gene in patients with arterial hypertension alone was 31% vs. 14%, χ2 = 5.496, p = 0,019, OR – 2,5 (1,2-5,0). The frequency of the wild allele A in these same patients was 69% versus 84%, χ2 = 5,496, p = 0,019, OR – 0,4 (0,2-0,8). A similar situation is determined with the AA genotype (52% versus 73%, χ2 = 3,609, p = 0,05), OR = 0,4 (0,1-0,9).</p></sec><sec><title>CONCLUSIONS</title><p>CONCLUSIONS: The association of the C521T and T704C polymorphisms, as well as the A1166C candidate genes AGT and AGTR1 with type 2 diabetes and arterial hypertension, is an important component in assessing the susceptibility to the development of these diseases in Dagestan residents.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сахарный диабет</kwd><kwd>артериальная гипертензия</kwd><kwd>генетический полиморфизм</kwd><kwd>ренин-ангиотензин-альдостероновая система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetes mellitus</kwd><kwd>essential arterial hypertension</kwd><kwd>genes polymorphism</kwd><kwd>renin-angiotensin-aldosterone system</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет средств государственного задания Дагестанского государственного медицинского университета.</funding-statement><funding-statement xml:lang="en">This work was carried out at the expense of the state assignment of the Dagestan State Medical University.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hivert MF, Vassy JL, Meigs JB.
