В связи с этим в настоящее время одной из важнейших задач является поиск дополнительных звеньев патогенеза SARS-CoV-2.</p><p>Целью исследования явился анализ уровня липополисахарид-связывающего белка (ЛСБ) и пресепсина (sCD14-ST) у пациентов с поражением легких вирусом SARS-CoV-2 различной степени тяжести, проживающих в Республике Крым. </p><sec><title>Материалы и методы</title><p>Материалы и методы. Обследованы госпитализированные в инфекционное отделение Государственного бюджетного учреждения здравоохранения Республики Крым «Республиканская клиническая больница имени Н.А.Семашко» больные (n = 121; возраст – 45–75 лет), у которых получен положительный результат теста на инфицирование SARS-CoV-2, проведенного методом полимеразной цепной реакции. По степени тяжести течения заболевания пациенты были распределены в 3 клинические группы (1-я – средней тяжести, 2-я – тяжелое, 3-я – лица, у которых в дальнейшем был зарегистрирован летальный исход). На момент поступления в стационар у больных проводилось исследование уровней ЛСБ, пресепсина, ферритина и С-реактивного белка в периферической крови. </p></sec><sec><title>Результаты</title><p>Результаты. У поступивших на стационарный этап лечения больных НКИ с поражением легких вирусом SARS-CoV-2 выявлено достоверное повышение всех изучаемых параметров, что отражает состояние липополисахарид-связывающих систем и системного воспаления. Наивысшие показатели ЛСБ, пресепсина и ферритина зарегистрированы у умерших (3-я группа). Установлено наличие прямой корреляционной связи между уровнями ЛСБ и sCD14-ST во 2-й (r = 0,523; p &lt; 0,05) и 3-й (r = 0,748; p &lt; 0,05) группах. </p></sec><sec><title>Заключение</title><p>Заключение. У больных с поражением легких SARS-CoV-2 при поступлении в стационар выявлено значительное повышение концентрации в крови ЛСБ и пресепсина, наибольший уровень отмечен у умерших. При тяжелом течении поражения легких вирусом SARSCoV-2 установлено наличие прямой корреляционной связи между уровнями ЛСБ и sCD14-ST. Таким образом, пресепсин, ЛСБ и ферритин являются важными прогностическими маркерами тяжелого течения поражения легких при инфицировании SARS-CoV-2 и риска летального исхода на ранних этапах госпитального лечения.</p></sec></abstract><trans-abstract xml:lang="en"><p>Although more than 2 years have passed since the beginning of the pandemic of the new coronavirus infection, treatment and prediction of the course of SARS-CoV-2 infection remain pressing global problems. In this regard, the search for additional links in the pathogenesis of SARS-CoV-2 is currently one of the most important tasks.</p><sec><title>The Aim</title><p>The Aim. To assess the level of lipopolysaccharide-binding protein (LBP) and presepsin (sCD14-ST) in patients with SARS-CoV-2 viral lung disease in Crimea.</p></sec><sec><title>Methods</title><p>Methods. We examined 121 patients with a positive PCR result for SARS-CoV-2 in the age group of 45 – 75 years who were hospitalized in the Department of Infectious Diseases, State Budgetary Healthcare Institution of the Republic of Crimea “N.A.Semashko Republican Clinical Hospital”. Patients were divided into 3 clinical groups according to the severity of SARS-CoV-2 infection: Group 1 – patients with moderate disease, Group 2 – patients with severe disease, and Group 3 – patients with fatal outcome. Peripheral blood levels of LBP, presepsin, ferritin, and C-reactive protein were determined upon admission to the infectious disease hospital.</p></sec><sec><title>Results</title><p>Results. A significant increase in all studied parameters was observed in the 1st, 2nd and 3rd clinical groups of patients with coronavirus infection. This finding corresponds to the state of lipopolysaccharide-binding systems and systemic infection in patients with SARS-CoV-2 viral lung disease. The highest levels of LBP, sCD14-ST, and ferritin were registered in the 3rd clinical group. We found a direct correlation between LBP and sCD14-ST levels in the 2nd group (r = 0.523, p &lt; 0.05) and the 3rd group (r = 0.748, p &lt; 0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. Patients with SARS-CoV-2 lung disease were found to have an increased blood levels of LBP and presepsin upon admission. The highest values were observed in patients with fatal outcome. Severe SARSCoV-2 lung damage was associated with a direct correlation between levels of LBP and sCD14-ST. Presepsin, LBP, and ferritin are important prognostic markers for severe SARS-CoV-2 lung damage and risk of death in the early stages of hospital treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>SARS-CoV-2</kwd><kwd>С-реактивный белок</kwd><kwd>липополисахарид-связывающий белок</kwd><kwd>пресепсин</kwd><kwd>поражение легких</kwd></kwd-group><kwd-group xml:lang="en"><kwd>SARS-CoV-2</kwd><kwd>C-reactive protein</kwd><kwd>lipopolysaccharide-binding protein</kwd><kwd>presepsin</kwd><kwd>lung damage</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Федерального государственного автономного образовательного учреждения высшего образования «Крымский федеральный университет имени В.И.Вернадского» Министерства науки и высшего образования Российской Федерации № ВГ14 / 2020 в Центре коллективного пользования научным оборудованием «Молекулярная биология» Медицинской академии имени С.И.Георгиевского Федерального государственного автономного образовательного учреждения высшего образования «Крымский федеральный университет имени В.И.Вернадского» Министерства науки и высшего образования Российской Федерации.</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">Worldmeter.
