The study included 80 patients with IS, 58 of whom had documented CI no later than 4 months prior to inclusion in the study. The comparison group consisted of 22 patients with IS who had not had any infectious diseases in the previous 4 months. The pathogenetic subtype of IS was determined according to the generally accepted SSS-TOAST classification. Stroke severity was assessed using the National Institutes of Health Stroke Scale (NIHSS), and functional outcome was assessed using the modified Rankin Scale (mRS). In addition to routine laboratory tests, serum concentrations of a number of cytokines were determined in all patients using enzyme-linked immunosorbent assay. The list of measured parameters included interleukin 6 (IL6), monocyte chemoattractant protein 1 (MCP1), and interferon gamma (IFNγ). Only patients who did not receive thrombolytic therapy for various reasons were included in the study.</p></sec><sec><title>Results</title><p>Results. In the main group, the proportion of patients with an unfavourable outcome (mRS ≥3) was 69%, while in the comparison group it was 23%. In all patients with IS who had COVID-19, a significant increase in the levels of leading mediators of the pro-inflammatory cytokine cascade, such as IL6 (p&lt;0.05), MSP1 (p&lt;0.05), acute phase proteins – CRP (p&lt;0.05) and ferritin (p&lt;0.05) was recorded in the peripheral bloodstream. These processes are observed against the background of a decrease in IFNγ content (p&lt;0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. Patients with IS who have had COVID-19 have higher mRS scores at discharge, accompanied by elevated serum inflammatory markers. Given the results obtained, the most likely mechanisms for this effect may be systemic inflammation and endothelial dysfunction induced by COVID-19, as well as hypercoagulability syndrome, which contributes to a more severe course of stroke.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Цель исследования – оценка функциональных исходов ишемического инсульта (ИИ) в зависимости от уровня биологических маркеров воспаления в сыворотке крови у пациентов, перенесших коронавирусную инфекцию (КИ) COVID-19.</p><sec><title>Материал и методы</title><p>Материал и методы. В исследование включено 80 пациентов с ИИ, из которых 58 человек перенесли документально подтвержденную КИ не позднее 4 мес до включения в исследование. Контрольную группу составили 22 пациента с ИИ, не болевшие инфекционными заболеваниями в течение последних 4 мес. Патогенетический подтип ИИ устанавливался по общепризнанной классификации SSS-TOAST. Тяжесть инсульта оценивали по шкале инсульта Национального института здоровья (NIHSS), функциональный исход – по Модифицированной шкале Рэнкина (mRS). В дополнение к рутинным лабораторным исследованиям у всех пациентов проводилось определение концентраций ряда цитокинов в сыворотке крови с использованием твердофазного иммуноферментного анализа. В перечень определяемых показателей входили интерлейкин 6 (ИЛ6), моноцитарный хемоаттрактантный белок 1 (МСР1) и интерферон гамма (ИФНγ). В исследование были включены только те пациенты, которым по различным причинам не проводилась тромболитическая терапия.</p></sec><sec><title>Результаты</title><p>Результаты. В основной группе доля пациентов с неблагоприятным исходом (mRS ≥3) составила 69%, в то время как в контрольной группе – 23%. У всех пациентов с ИИ, перенесших COVID-19, в периферическом кровотоке регистрируется значимое возрастание уровней ведущих медиаторов провоспалительного цитокинового каскада, таких как ИЛ6 (р&lt;0,05), МСР1 (р&lt;0,05), белков острой фазы – С-реактивного белка (р&lt;0,05) и ферритина (р&lt;0,05). Данные процессы отмечаются на фоне снижения содержания ИФНγ (р&lt;0,05).</p></sec><sec><title>Заключение</title><p>Заключение. Пациенты с ИИ, перенесшие COVID-19, имеют более высокие баллы по mRS при выписке, что сопровождается повышенным содержанием маркеров воспаления в сыворотке крови. Учитывая полученные результаты, наиболее вероятными механизмами этого эффекта могут быть системное воспаление и эндотелиальная дисфункция, индуцированные COVID-19, а также гиперкоагуляционный синдром, способствующий более тяжелому течению инсульта.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цереброваскулярные заболевания</kwd><kwd>ишемический инсульт</kwd><kwd>коронавирусная инфекция</kwd><kwd>патогенетический подтип инсульта по классификации SSS-TOAST</kwd><kwd>Модифицированная шкала функциональных исходов Рэнкина (mRS)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cerebrovascular diseases</kwd><kwd>ischemic stroke</kwd><kwd>coronavirus infection</kwd><kwd>pathogenetic subtype of stroke according to the SSS-TOAST classification</kwd><kwd>modified Rankin Scale (mRS)</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The investigation has not been sponsored</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">Feigin VL, Brainin M, Norrving B, et al.
