Индуцируемый гипоксией фактор-1α (HIF-1α), участвующий в регуляции уровня кислорода в тканях, играет важную роль в патофизиологии инсульта, включая выживаемость нейронов, нейровоспаление, ангиогенез, метаболизм глюкозы, проницаемость гематоэнцефалического барьера (ГЭБ), и имеет значение в исходах ишемического инсульта. Сведения о роли HIF-1α в развитии инсульта разноречивы. Эффекты влияния HIF-1α связаны с длительностью и тяжестью ишемии. Известно о роли HIF-1α в ишемическом повреждении головного мозга, включая воспалительную реакцию и потерю целостности ГЭБ после инсульта. Цель исследования – определение связи содержания гипоксией индуцированного фактора-1α в крови пациентов со степенью неврологического дефицита в остром периоде ишемического инсульта и исходом заболевания. Обследованы 58 человек с ишемическим инсультом в возрасте 73 (67-81) лет. Пациенты были разделены на две группы – выписанные и умершие. Определяли тяжесть инсульта (NIHSS), неврологический дефицит, индекс коморбидности, содержание в крови HIF-1α, белка р53, интерлейкина-6, цистатина С, СРБ, креатинина, гематологические показатели при поступлении, на 3-и и 10-е сутки заболевания. Содержание HIF-1α в крови пациентов с ИИ при поступлении было ниже, чем в группе сравнения и оставалось сниженным до 10-го дня наблюдения. На 10-е сутки определялась связь HIF-1α с NIHSS, неврологическим дефицитом, индексом коморбидности и исходом заболевания. Наблюдали обратную связь HIF-1α с содержанием эритроцитов, гемоглобина и гематокрита что можно расценивать как отражение гемической составляющей смешанной гипоксии. Также у пациентов с неблагоприятным исходом ИИ выявлено повышенное содержание цистатина С в крови, которое было связано с концентраций HIF-1α. Во все сроки наблюдения церебральной катастрофы была отмечена корреляционная связь цистатина С с содержанием креатинина и СРБ. Эти результаты могут свидетельствовать о дисфункции эндотелиоцитов, нарушении клубочковой фильтрации, воспалении, ассоциированными с гипоксией при ИИ. Прогностическая значимость уровня HIF-1α в крови на 10-е сутки заболевания для исхода ИИ составила AUC = 0,900. Содержание HIF-1α в крови в остром периоде связано с тяжестью ишемического инсульта и исходом заболевания.</p></abstract><trans-abstract xml:lang="en"><p>Ischemic stroke (IS) occurs as a result of local disturbance of hemocirculation and hypoxia in the brain tissue. Hypoxia-inducible factor-1α (HIF-1α), which is involved in the regulation of tissue oxygen levels, plays an important role in the pathophysiology of stroke, including neuronal survival, neuroinflammation, angiogenesis, glucose metabolism, blood-brain barrier permeability, and is important in IS outcomes. The purpose of the study was to determine the relationship between blood levels of HIF-1α and the degree of neurological deficit in the acute period of IS and the outcome of the disease. We examined 58 people with IS aged 73 (67-81) years. Patients were divided into two groups – discharged and dead. The severity of stroke (NIHSS), neurological deficit, comorbidity index, blood levels of HIF-1α, p53 protein, interleukin-6, cystatin C, CRP, creatinine, hematological parameters were determined at admission, on days 3 and 10 of the disease. At admission the blood levels of HIF-1α was lower than in the comparison group and remained reduced until the 10th day. On day 10 the association of HIF-1α with neurological deficit, comorbidity index and disease outcome was determined. We observed a feedback of HIF-1α with the content of erythrocytes, hemoglobin and hematocrit, which can be regarded as a reflection of the hemic component of mixed hypoxia. In dead patients, an increased blood level of cystatin C was detected, which was associated with HIF-1α concentrations. In all periods of observation of IS, a correlation between cystatin C and creatinine and CRP levels was noted. These results may indicate dysfunction of endotheliocytes, inflammation associated with hypoxia in IS. The prognostic significance of the blood level of HIF-1α on the 10th day for the outcome of IS was AUC = 0.900. Blood levels of HIF-1α in the acute period was associated with the severity of IS and the outcome of the disease.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипоксией индуцированный фактор-1α</kwd><kwd>апоптоз</kwd><kwd>маркеры воспаления</kwd><kwd>цистатин С</kwd><kwd>ишемический инсульт</kwd><kwd>исход</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypoxia-induced factor-1α</kwd><kwd>apoptosis</kwd><kwd>markers of inflammation</kwd><kwd>cystatin C</kwd><kwd>ischemic stroke</kwd><kwd>outcome</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">Barteczek P., Li L., Ernst A.S., Böhler L.I., Marti H.H., Kunze R.
