Материалы и методы. Исследование проведено на базе Самарской областной детской инфекционной больницы с 2021 по 2022 гг. Обследовано 40 пациентов со среднетяжелой (n = 20, I группа) и тяжелой формами (n = 20, II группа) COVID-19, группу сравнения составили пациенты с вирусной пневмонией другой этиологии (n = 35, III группа). Результаты. Новая коронавирусная инфекция, вызванная вирусом SARS-CoV-2, индуцирует высокие уровни цитокинов IL-6 (р &lt; 0,005), IL-8 (р &lt; 0,05) и незначительное повышение TNF-α (р &lt; 0,05). Уровень IL-8 достоверно связан с длительностью болезни (р &lt; 0,01). Вероятно, значение данного интерлейкина будет повышаться в постковидном периоде. Выводы. Изменение уровней IL-6 и IL-8 у пациентов с COVID-19, наряду с клиническими особенностями, являются важными биомаркерами для прогнозирования тяжести и длительности течения заболевания.</p></abstract><trans-abstract xml:lang="en"><p>A new coronavirus infection caused by the SARS-CoV-2 virus is characterized by a systemic hyperinflammatory response with a pronounced increase in the content of pro-inflammatory cytokines. Materials and methods. The study was conducted on the basis of the Samara Regional Children's Infectious Diseases Hospital from 2021 to 2022. 40 patients with moderate (n = 20, group I) and severe forms (n = 20, group II) COVID-19 were studied, the comparison group consisted of patients with viral pneumonia of another etiology (n = 35, group III). Results. The infectious agent SARS-CoV-2 induces high levels of cytokines IL-6 (p &lt; 0.005), IL-8 (p &lt; 0.05) and a slight increase in TNF-α (p &lt; 0.05). IL-8 was significantly associated with disease duration (p &lt; 0.01). We assume that the value of this interleukin will increase in the post-COVID period. Conclusions. Changes in IL-6 and IL-8 levels in patients with COVID-19, along with clinical features, are important biomarkers for predicting the severity and duration of the disease.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>дети</kwd><kwd>интерлейкины</kwd><kwd>IL-6</kwd><kwd>IL-8</kwd><kwd>TNF-α</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>children</kwd><kwd>interleukin levels</kwd><kwd>IL-6</kwd><kwd>IL-8</kwd><kwd>TNF-α</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">World Health Organization.
