Сердечно-сосудистые заболевания все чаще ассоциированы с такими патологиями, как нарушение толерантности к глюкозе и сахарный диабет (СД) 2-го типа. Такое сочетание вызывает целый ряд отрицательных явлений в организме, увеличивая вероятность возникновений риска тромботических осложнений, негативно сказываясь на общем прогнозе заболеваний. Тромбоциты тесно связаны с началом и распространением тромбоза.</p></sec><sec><title>Цель работы</title><p>Цель работы: изучить особенности коллаген-индуцированной aгрегации тромбоцитов у пaциентов с нарушением толерантности к углеводам (НТУ) или с СД 2-го типа в сочетании с артериальной гипертензией (АГ) и возможность реализации эффекта через цАМФ^висимую сигнальную систему.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведено одномоментное поперечное исследование, в которое были включены 37 пациентов с АГ и метаболическими нарушениями в возрасте 40-65 лет и 20 здоровых добровольцев. В сыворотке крови иммунотурбидиметрическим методом выполняли количественное определение показателей углеводного обмена (глюкозы и гликозилированного гемоглобина). Агрегационную активность тромбоцитов исследовали турбидиметрическим методом на двухканальном лазерном анализаторе, определяли степень и скорость агрегации богатой тромбоцитами плазмы по кривым светопропускания и среднего размера агрегатов под влиянием индуктора коллагена. Внутриклеточную концентрацию цАМФ тромбоцитов увеличивали прединкубацией в течение 30 мин: с форсколином (Sigma) стимулятором аденилатциклазы и 3-изобутил-1-метилксантина (Sigma) ингибитором фосфодиэстеразы 3 и 5 в конечных концентрациях 100 мкМ.</p></sec><sec><title>Результаты</title><p>Результаты. Получено повышение коллаген-индуцированной агрегации и увеличение размера агрегатов у пациентов с НТУ в сочетании с АГ. Выявлены корреляционные связи между уровнем гликозилированного гемоглобина, степенью агрегации и размером агрегатов тромбоцитов у пациентов двух групп, а у пациентов с СД 2-го типа в сочетании с АГ - размера агрегатов со стажем заболевания.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные результаты указывают на дисрегуляцию цАМФ-опосредованной сигнальной системы, связанную с хронической гипергликемией у исследуемых групп пациентов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Cardiovascular diseases are increasingly associated with pathologies, such as impaired glucose tolerance and type 2 diabetes mellitus (T2DM). This combination causes several negative phenomena in the body, increasing the likelihood of thrombotic complications and negatively affecting the overall prognosis of the diseases. Platelets are closely related to the onset and spread of thrombosis.</p></sec><sec><title>Objective</title><p>Objective. To study collagen-induced platelet aggregation and to elucidate the mechanism of action through the cyclic adenosine monophosphate (cAMP)-dependent signaling system in patients with impaired carbohydrate tolerance or T2DM in combination with hypertension.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. A cross-sectional study was conducted. The study included 37 patients with hypertension and metabolic disorders aged 40-65 years and 20 healthy volunteers. Serum parameters of carbohydrate metabolism (glucose and glycosylated hemoglobin) were quantitatively determined by the immunoturbidimetric method. Platelet aggregation activity was investigated by turbidimetry with a two-channel laser analyzer. The degree and the rate of platelet aggregation in platelet-rich plasma were determined based on the curves of light transmission and platelet aggregate mean size in the presence of collagen. Intracellular concentrations of cAMP in platelets were increased by preincubation with adenylate cyclase activator, Forskolin (Sigma), and phosphodiesterase type 3 and 5 inhibitor, 3-isobutyl-1-methylxanthine (Sigma), at final concentrations of 100 ^m for 30 min.</p></sec><sec><title>Results</title><p>Results. An increase in collagen-induced platelet aggregation and size increase of platelet aggregates were observed in patients with impaired carbohydrate tolerance in combination with hypertension. The correlation relationships were detected between the level of glycosylated hemoglobin, degree of platelet aggregation, and size of platelet aggregates in patients of two groups. The correlation relationships were also detected between the size of platelet aggregates and the duration of the disease in patients with type 2 diabetes in combination with hypertension.</p></sec><sec><title>Conclusions</title><p>Conclusions. The obtained results suggest a dysregulation in the cAMP-mediated signaling system associated with chronic hyperglycemia in study patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тромбоцит</kwd><kwd>агрегация</kwd><kwd>агрегат</kwd><kwd>сахарный диабет</kwd><kwd>нарушение толерантности к глюкозе</kwd><kwd>артериальная гипертензия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>platelets</kwd><kwd>aggregation</kwd><kwd>aggregate</kwd><kwd>diabetes mellitus</kwd><kwd>impaired glucose tolerance</kwd><kwd>hypertension</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bondarenko I.Z.
