Продемонстрирован факт укорочения в теломерах концевых участков хромосом при интермиттирующей ночной гипоксии и фрагментации сна у пациентов с СОАС, при этом устранение патофизиологических триггеров СОАС способствовало увеличению относительной длины теломер. Актуальным представляется поиск взаимосвязи теломер и активности теломеразного комплекса (ТК) со структурными компонентами сна, показателями насыщения крови кислородом при СОАС.</p><p>Целью исследования явилась оценка активности основных компонентов ТК и определение его взаимосвязи со структурными компонентами сна и уровнем десатурации у пациентов с СОАС.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Основную (1-ю) группу составили пациенты (n = 32: 100 % – мужчины; средний возраст – 51,2 ± 3,1 года) с жалобами на храп, остановки дыхания во время сна, повышенную дневную сонливость. Контрольную группу (2-ю) составили добровольцы (n = 26) без клинических проявлений СОАС, подобранные по типу «копия–пара». Обострений хронических заболеваний у пациентов обеих групп не установлено. В рамках исследования проводились анкетирование, полисомнографический мониторинг, определение относительной длины теломер методами полимеразной цепной реакции и иммуноферментного анализа для оценки активности основных компонентов ТК, статистические методы анализа.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлены достоверные различия в функционировании теломер и ТК – теломеразной обратной транскриптазы (TERT) и белка-1, ассоциированного с теломеразой теломеразной субъединицы (TEP1), определена значимая положительная взаимосвязь в 1-й группе с уровнями сатурации крови кислородом, теломер и активностью ТЕР1.</p></sec><sec><title>Заключение</title><p>Заключение.

The blockage is caused by intermittent throat collapse and thereby no lung ventilation with preserved respiratory efforts. Earlier we demonstrated that telomeres at the end of chromosomes shorten during intermittent nocturnal hypoxia and sleep fragmentation in OSA patients; the elimination of OSA triggers contributed to an increase in relative telomere length (RTL). The search for the relationship between telomeres and the telomerase complex activity with the sleep stages, as well as indicators of blood oxygen saturation in OSA, seems relevant.</p><sec><title>Aim</title><p>Aim. To evaluate the activity of the telomerase complex main components and to determine its relationship with the sleep phases and the level of desaturation in patients with OSA.</p></sec><sec><title>Methods</title><p>Methods. The main group included 32 men (age 51.2 ± 3.1 years) with complaints of snoring, respiratory arrest during sleep, and increased daytime sleep. The control group consisted of 26 matched volunteers without clinical manifestations of OSA. Patients of both groups did not have any exacerbations of their chronic conditions at baseline. The study included questionnaires, polysomnography monitoring, analysis of the RLT by PCR, ELISA to determine activity of the telomerase complex components, and statistical analysis.</p></sec><sec><title>Results</title><p>Results.
