Оценить эффективность супероксиддисмутазы (СОД) в качестве маркера для прогнозирования когнитивных нарушений в конце острого периода инфаркта мозга (ИМ) у пациентов с апноэ во сне (АС).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Было обследовано 74 пациента в остром периоде ИМ с сопутствующим АС и 36 пациентов с ИМ без АС. Всем пациентам выполнялась респираторная полиграфия, определение когнитивных нарушений с помощью Монреальской шкалы оценки когнитивных функций и исследование СОД крови.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено пороговое значение показателя активности СОД сыворотки ≤ 47,9 единиц активности, являющееся прогностическим маркером нарушений зрительно-конструктивных / исполнительных навыков (AUC — 0,725 (95 % ДИ 0,609–0,823; р = 0,003); чувствительность — 70,9 % (95 % ДИ 58,1–81,8); специфичность — 66,7 % (95 % ДИ 34,9–90,1)) и отсроченного воспроизведения (AUC — 0,701 (95 % ДИ 0,584–0,802; р = 0,005); чувствительность — 70,5 % (95 % ДИ 57,4–81,5); специфичность — 61,5 % (95 % ДИ 31,6–86,1)) в конце острого периода ИМ у пациентов с АС.</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с АС пороговое значение показателя активности СОД крови ≤ 47,9 единиц активности может быть использовано как классификатор хорошего качества для выделения групп риска развития нарушений зрительно-конструктивных / исполнительных навыков и отсроченного воспроизведения начиная с первых дней ИМ и планирования им лечебных и реабилитационных мероприятий, в том числе назначения терапии постоянным положительным давлением в дыхательных путях.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To evaluate the effectiveness of superoxide dismutase (SOD) as a marker for predicting cognitive impairment at the end of the acute period of cerebral infarction (CI) in patients with sleep apnea (SA).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Seventy four patients in the acute period of CI and concomitant SA and 36 patients with СI without AS were examined. All patients underwent respiratory polygraphy, determination of cognitive impairment using the Montreal Cognitive Assessment, and blood SOD analysis.</p></sec><sec><title>Results</title><p>Results. A threshold value of serum SOD activity ≤47.9 activity units was established, which is a prognostic marker of impairments in visual-constructive/executive skills (AUC ‒ 0.725 (95% CI 0.609–0.823; p=0.003); sensitivity ‒ 70.9% (95% CI 58.1–81.8); specificity ‒ 66.7% (95% CI 34.9–90.1)) and delayed recall (AUC ‒ 0.701 (95% CI 0.584–0.802; p=0.005); sensitivity ‒ 70.5% (95% CI 57.4–81.5); specificity ‒ 61.5% (95% CI 31.6–86.1)) at the end of the acute period of CI in patients with SA.</p></sec><sec><title>Conclusion</title><p>Conclusion. In patients with SA the threshold value of the blood SOD activity indicator ≤47.9 activity units can be used as a good-quality classifier for identifying risk groups for the development of visual-constructive/executive skills disorders and delayed recall starting from the first days of the CI, and planning their treatment and rehabilitation measures including the appointment of continuous positive airway pressure therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>инфаркт мозга</kwd><kwd>апноэ во сне</kwd><kwd>когнитивные нарушения</kwd><kwd>супероксиддисмутаза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cerebral infarction</kwd><kwd>sleep apnea</kwd><kwd>cognitive impairment</kwd><kwd>superoxide dismutase</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The study was conducted without sponsorship</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">El Husseini N, Katzan IL, Rost NS, Blake ML, Byun E, Pendlebury ST, et al.
