Изучение роли амилоида-бета 40 (Aβ 40) в развитии когнитивных нарушений в остром периоде ишемического инсульта.Материал и методы. Обследованы 70 пациентов в возрасте 33–86 лет, из которых 46 мужчин и 24 женщины.У пациентов в остром периоде ишемического инсульта проводилась оценка когнитивного статуса (краткая шкала оценки психического статуса (MMSE), Монреальская шкала оценки когнитивных функций (MoCA), батарея лобных тестов (FAB), таблицы Шульте, тест рисования часов, тест на семантическую вербальную беглость и тест пяти слов). Также исследовалась концентрации Аβ 40 в ликворе, изучались морфометрические (размер очага инфаркта и площадь лейкоареоза, объем желудочков мозга и гиппокампов) и диффузионно-тензорные показатели (фракционная анизотропия скорлупы, таламуса, гиппокампа, мозолистого тела, ножек внутренней капсулы, цингулярного, верхнего продольного и нижнего фронто-окципитального пучков) магнитно-резонансной томографии.Результаты. Концентрация Аβ 40 в ликворе составила 436,4 (226,0–514,0) пг/мл и была ассоциирована с результатом субтестов «ориентация» (MMSE) и «внимание» (MoCA), а также опосредованным воспроизведением в MoCA. Пациенты с результатом MMSE 24–27 баллов характеризовались более низкой концентрацией Аβ 40 по сравнению с пациентами с результатом шкалы менее 24 баллов. Концентрация Аβ 40 более 436,4 пг/мл была связана с более выраженной соматической коморбидностью инсульта (артериальная гипертензия, более низкое содержание гемоглобина и альбумина крови, более высокая скорость оседания эритороцитов), меньшим объемом желудочков мозга, более низкой фракционной анизотропией таламусов, цингулярных пучков и контралатерального гиппокапма и ассоциирована с более низким глобальным когнитивным статусом (по результатам MMSE и MoCA), а также снижением отдельных когнитивных функций, а именно внимания, зрительно-пространственного гнозиса и памяти.Выводы. Концентрация Аβ 40 в спинномозговой жидкости является биологическим маркером как выраженности, так и характера постинсультных когнитивных нарушений, что, вероятно, опосредовано повреждением гиппокампов, таламуса и цингулярных трактов. При этом, на наш взгляд, биомаркер отражает как сосудистый, или ишемический, компонент патогенеза когнитивных нарушений в остром периоде ишемического инсульта, так и влияние амилоид-опосредованной нейродегенерации.</p></abstract><trans-abstract xml:lang="en"><p>Aim: to study the role of amyloid-beta 40 (Aβ 40) in the development of cognitive impairment in acute ischemic stroke.Materials and methods. The study included 70 patients aged 33–86 years, 46 men and 24 women. In patients with acute ischemic stroke cognitive status was assessed with Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Test (MoCA), Frontal Assessment Battery (FAB), Schulte tables, Clock Drawing Test, Test for Semantic Verbal Fluency and Five Words Test. The concentration of Aβ 40 in the cerebrospinal fluid was determined. Morphometric (size of the infarct and leukoaraiosis area, volume of the brain ventricles and hippocampus) and diffusion-tensor parameters of MRI (fractional anisotropy of putamen, thalamus, hippocampus, corpus callosum, limbs of the internal capsule, the cingulate, the superior longitudinal and inferior fronto-occipital tracts) were studied.Results. The concentration of Aβ 40 in the cerebrospinal fluid was 436,4 (226,0–514,0) pg/ml. The protein level was associated with the result of subtests «Orientation» (MMSE) and «Attention» (MoCA), as well as indirect recall with cues in MoCA. Patients with MMSE score of 24–27 points were characterized by a lower concentration of Aβ 40 as compared to patients with a score less than 24 points. Aβ 40 concentration more than 436,4 pg/mL was associated with a more severe somatic co-morbidity of stroke (hypertension, lower hemoglobin and albumin level, higher erythrocyte sedimentation rate), a smaller volume of the brain ventricles, lower fractional anisotropy of the thalamus, cingulate tracts and contralateral hippocampus. Aβ 40 concentration more than 436,4 pg/mL was also associated with a lower global cognitive status (according to the MMSE and MoCA), as well as the reduction in certain cognitive functions, namely, attention, visual-spatial functions and memory.Conclusions. The concentration of Aβ 40 in the cerebrospinal fluid is a biological marker of severity type of post-stroke cognitive impairment. This interaction is probably due to the damage to the hippocampus, thalamus and cingulate tracts. In our opinion, the biomarker reflects both ischemic and neurodegenerative components of the pathogenesis of cognitive impairment in acute ischemic stroke.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инсульт</kwd><kwd>амилоид</kwd><kwd>нейродегенерация</kwd><kwd>когнитивные нарушения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stroke</kwd><kwd>neurodegeneration</kwd><kwd>amyloid</kwd><kwd>fractional anisotropy</kwd><kwd>cognitive impairment</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">Левин О.С.
