In a group of 32 patients with combined ischemic heart disease (IHD) and arterial hypertension (AH) we studied dynamics of parameters of blood pressure and ECG 24-hour monitoring, as well as ultrasound structural and functional parameters of left and right ventricles during 3-month therapy with fixed dose combination of perindopril arginine (10.0 mg) and amlodipine (5.0 mg). The obtained results demonstrated significant positive effect of this combination on the geometry, structure and diastolic function of both left and right ventricles, as well as confirmed its high antiischemic and antihypertensive effects.
Цель. Сопоставить эффекты 3-месячной терапии фиксированной комбинацией ингибитора ангиотензинпревращающего фермента (периндоприла) и тиазидоподобного диуретика (индапамида) в генетически гетерогенных подгруппах больных артериальной гипертонией (АГ) для оценки возможности выбора режима антигипертензивной терапии, основанной на результатах генетического тестирования. Материал и методы. Для реализации поставленной цели обследован 41 больной АГ 1-2 степени с недостаточной эффективностью предшествующей антигипертензивной терапии и 20 здоровых лиц, для сравнения частоты встречаемости полиморфизма генов в Ростовской области. Больным АГ был выполнен стандартный объем обследования, а также молекулярно-генетическое исследование по определению наиболее клинически значимых полиморфных генов, участвующих в патогенезе АГ. Результаты. Установлена связь между клиническими и морфофункциональными особенностями АГ у обследованного контингента больных с полиморфизмом генов AGT, AGTR2, CYP11B2, GNB3, NOS3: -786, из которых 3 полиморфных гена (AGT, AGTR2, CYP11B2) кодируют активность ангиотензинпревращающего фермента. Проведена оценка терапевтической эффективности назначения в качестве стартовой антигипертензивной терапии препарата из класса ингибиторов ренин-ангиотензин-альдостероновой системы в классической комбинации с тиазидоподобным диуретиком. Сопоставление эффектов использованной фиксированной комбинации периндоприла (10,0) и индапамида (2,5) (Нолипрел А Би-форте) в генетически гетерогенных подгруппах больных АГ позволило установить более выраженные антигипертензивные и органопротективные эффекты у лиц, имеющих в генотипе "мутантную" аллель 704C полиморфизма T704C AGT. Продемонстрировано достоверно более значимое снижение артериального давления по стандартным показателям суточного мониторирования артериального давления (p<0,05). Достоверно более значимое уменьшение индекса массы миокарда левого желудочка (p=0,0001), а также достоверное увеличение показателя трансмитрального кровотока (VЕ/VА МК), p=0,0024. Положительное влияние терапии на все показатели жесткости артериальной стенки: уменьшение параметров скорости пульсовой волны (p=0,0035), сосудистого возраста (VA) (p=0,00002) и индекса отражения (Ri) (p=0,000001), по сравнению с пациентами с отсутствием носительства "мутантной" аллели 704С гена AGT. Заключение. Полученные результаты свидетельствует о перспективности использования генетических подходов для выработки персонифицированной тактики медикаментозного лечения больных АГ с целью повышения ее эффективности.Ключевые слова: артериальная гипертензия, полиморфизм генов, ренинангиотензин-альдостероновая система, ингибитор ангиотензинпревращающего фермента.

Introduction. Organotin compounds are promising candidates for antitumor drugs. Identification of pathogenetic features of the general toxic effect of hybrid organotin compounds during the period of the greatest severity of the intoxication clinical picture will allow to estimate the risk of hepatotoxic and nephrotoxic complications with the administration of bis (3,5–di– tert–butyl–4–hydroxyphenylthiolate) dimethyltin (Me-3) and ((3,5–di–tert–butyl–4–hydroxyphenylthiolate) triphenyltin (M-e5) as chemotherapeutic agents.Аim: To conduct a comparative analysis of morphological and biochemical changes with a single intragastric administration of hybrid organotin compounds Me-3 and Me-5 in the maximum tolerated dose (MTD) on the 7th day of the toxic process development.Material and Methods. Hybrid organotin compounds Me-3 and Me-5 were administered once intragastrically to Wistar rats (females) at a MTD of 2000 mg/kg and 750 mg/kg, respectively. Biochemical and morphological studies were carried out on the 7th day of the development of intoxication symptoms according to standard methods.Results. With the introduction of Me-3 and Me-5 in the liver, signs of fatty dystrophy of varying severity were revealed, with a predominant lesion of centrolobular hepatocytes, an increase in the size of portal tracts due to edema and fibrosis, and scant lymphocytic infiltration. With the introduction of Me-5, morphological changes were more severe, with the involvement of the vascular bed of the organ in the process. When the tested compounds were administered in the kidneys, the same type of damage to the glomerular apparatus and renal tubules was recorded, characteristic of toxic nephropathy. Unidirectional changes in the blood of experimental animals were revealed in the group of nonspecific biochemical markers of cytolysis: a moderate decrease in transaminase activity and an increase in the activity of creatine kinase (CC), lactate dehydrogenase (LDH) and creatinine levels. The process of formation of urea and protein synthesis was functionally preserved.Conclusion. On the 7th day of the development of intoxication with a single intragastric administration of hybrid organotin compounds Me-3 and Me-5 in the maximum tolerated doses, biochemical and morphological changes in the body of animals could be attributed to a moderate degree of severity.
