Because of the high rate of severe complications, both early etiotropic and pathogenetic therapy and timely diagnosis are crucial.</p> <p><bold>AIM:<italic> </italic></bold>To analyze the current clinical and epidemiological characteristics of sepsis using data from a multidisciplinary medical facility.</p> <p><bold>METHODS:</bold> A cohort study of epidemiological and clinical data on sepsis cases recorded at the S.P. Botkin Clinical Infectious Diseases Hospital from 2019 to 2024 was conducted. Medical records of patients hospitalized with sepsis from January to June 2025 were also reviewed.</p> <p><bold>RESULTS:</bold> From 2019 to 2024, 356 sepsis cases were recorded. The highest mortality rates occurred in 2022 and 2023: 32.4% and 41.7%, respectively. The most common etiologies were unspecified sepsis, staphylococcal sepsis, and sepsis due to gram-negative organisms. Mortality was highest in meningococcal and streptococcal septicemia and gram-negative sepsis. At onset, flu-like symptoms and intestinal dysfunction were noted, followed by systemic inflammatory response syndrome, multiple organ failure, coagulation disturbances, and cardiovascular complications. The mean age was 50.5 ± 15.5 years. Risk factors included extensive comorbidities, trauma, surgery, drug addiction, alcoholism, and low social status.</p> <p><bold>CONCLUSION:</bold> The rising incidence of septic complications, predominance of working-age patients with increased comorbidity, flu-like symptoms, and signs of acute intestinal infection at onset should raise awareness among physicians of all specialties for the timely detection of systemic inflammation and initiation of adequate treatment.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Сепсис — патологический процесс генерализованного воспаления в ответ на инфекцию различной природы, сочетающийся с полиорганной дисфункцией, нарушениями гемодинамики и системы гемостаза. В связи с большим количеством тяжелых осложнений на первый план для изучения выходят не только раннее назначение этиотропной и патогенетической терапии, но и своевременная диагностика сепсиса.</p> <p><bold>Цель исследования.</bold> Проанализировать современную клинико-эпидемиологическую структуру сепсиса по данным многопрофильной медицинской организации.</p> <p><bold>Материалы.</bold> Проведено когортное исследование эпидемиологических и клинических данных случаев сепсиса с 2019 по 2024 г., зарегистрированных в Клинической инфекционной больнице им. С.П. Боткина. Выполнен также анализ историй болезни пациентов с сепсисом, госпитализированных в стационар с января по июнь 2025 г.</p> <p><bold>Результаты.</bold> За период с 2019 по 2024 г. зарегистрировано 356 случаев сепсиса. Максимальное количество летальных исходов приходилось на 2022 и 2023 гг. — 32,4 и 41,7% соответственно. В этиологической структуре сепсиса преобладали такие типы, как неуточненный, стафилококковый и вызванный грамотрицательными микроорганизмами сепсис. Максимальную летальность наблюдали при менингококковой, стрептококковой септицемии и грамотрицательном сепсисе. В дебюте развивающегося сепсиса отмечена гриппоподобная симптоматика, признаки кишечной дисфункции с последующим развитием синдрома системного воспалительного ответа, полиорганной недостаточности, нарушения системы коагуляции и сердечно-сосудистых осложнений. Средний возраст пациентов составил 50,5±15,5 года. Факторами риска, способствующими возникновению сепсиса, были обширная коморбидная патология, травмы, оперативные вмешательства, наркомания, алкоголизм и низкий социальный статус пациентов.</p> <p><bold>Заключение.</bold> Увеличение количества случаев септических осложнений в последние годы, преобладание лиц трудоспособного возраста с повышенным коморбидным фоном среди больных, гриппоподобный синдром и признаки острой кишечной инфекции в дебюте заболевания должны способствовать повышению настороженности врачей различных специальностей, направленной на своевременное выявление системного воспалительного ответа, а также адекватной и своевременной терапии сепсиса.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>sepsis</kwd><kwd>septic complications</kwd><kwd>systemic inflammatory response syndrome</kwd><kwd>multiple organ failure</kwd><kwd>septic shock</kwd><kwd>staphylococcal sepsis</kwd><kwd>unspecified sepsis</kwd><kwd>respiratory syndrome</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сепсис</kwd><kwd>септические осложнения</kwd><kwd>синдром системного воспалительного ответа</kwd><kwd>полиорганная недостаточность</kwd><kwd>септический шок</kwd><kwd>стафилококковый сепсис</kwd><kwd>неуточненный сепсис</kwd><kwd>респираторный синдром</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Vershinina MG, Steriopolo NA, Ibragimova VYu.
