Хронические сердечно-сосудистые заболевания сопровождаются дисфункцией эндотелия и являются факторами риска развития тяжелых форм гриппа и неблагоприятного прогноза. Учитывая значимую роль нарушений в системе гемостаза в развитии сердечно-сосудистой патологии при тяжелых формах инфекционных заболеваний, представляется актуальным изучение состояния гемостаза при гриппе. Цель: оценка состояния гемостаза у взрослых пациентов с осложненными и неосложненными формами гриппа. Материалы и методы: проведен анализ историй болезни 64 пациентов с гриппом в возрасте от 19 до 90 лет, находившихся на стационарном лечении в Республиканской клинической инфекционной больнице им. профессора А.Ф. Агафонова в период с 1.12.2023 по 1.03.2024. Медиана возраста пациентов составила 65 лет. У 61 пациента (95%) был диагностирован грипп А, в большинстве случаев (50 человек) обусловленный вирусом гриппа А/H1N1, в 11 – вирусом гриппа А/ H3N2. У 3 пациентов (5%) был диагностирован грипп В. У 32 больных (50%) грипп осложнился пневмонией, диагноз которой был установлен по результатам проведенной компъютерной томографии органов грудной клетки. Хронические сердечно-сосудистые заболевания регистрировались у 45 пациентов (70%). Оценка системы гемостаза проводилась по количеству в крови тромбоцитов, уровню Д-димера, значениям протромбинового времени, протромбинового индекса, МНО и АЧТВ. Результаты: было установлено, что острый период гриппа сопровождается повышением в крови уровня Д-димера, значения которого статистически значимо отличались от показателя группы контроля. Медиана Д-димера у пациентов с гриппом была в 4,9 раза выше, чем в контрольной группе (р=0,000). Уровень Д-димера у пациентов, имевших в анамнезе сердечно-сосудистые заболевания, был в 2,5 раза выше по сравнению с больными без указанной патологии (р=0,02). У больных гриппом, осложненной пневмонией, медиана Д-димера была в 3,8 раза выше по сравнению с пациентами без пневмонии (р=0,0009). Среди умерших пациентов медиана Д-димера при госпитализации была в 2,8 раза выше по сравнению с выжившими (р=0,003). Уровень Д-димера выше 3000 нг/мл у пациентов с гриппом, осложненным пневмонией, ассоциировался с высоким риском летального исхода (р&lt;0,05). Заключение: у пациентов с гриппом, осложненным пневмонией, отмечается повышение в крови уровня Д-димера, что создает условия для развития тромботических осложнений.</p></abstract><trans-abstract xml:lang="en"><p>Influenza remains the most significant acute respiratory viral infection due to its high incidence rate, potential for severe disease progression, and complications. Chronic cardiovascular diseases, which are associated with endothelial dysfunction, represent risk factors for severe influenza outcomes and poor prognosis. Given the important role of hemostatic disorders in the development of cardiovascular pathology during severe infectious diseases, studying hemostasis in influenza appears highly relevant. Research Objective: To evaluate hemostatic parameters in adult patients with complicated and uncomplicated influenza. Materials and Methods. We analyzed medical records of 64 influenza patients aged 19 to 90 years hospitalized at the Professor A.F. Agafonov Republican Clinical Infectious Diseases Hospital (GAUZ “RKIB”) between December 1, 2023, and March 1, 2024. The median patient age was 65 years. Influenza A was diagnosed in 61 patients (95%), predominantly caused by A/H1N1 (50 cases) and A/H3N2 (11 cases). Three patients (5%) had influenza B. Pneumonia, confirmed by chest CT, complicated influenza in 32 patients (50%). Chronic cardiovascular diseases were present in 45 patients (70%). Hemostasis was assessed through platelet count, Ddimer level, prothrombin time (PT), prothrombin index (PTI), INR, and aPTT. Results. The acute phase of influenza was associated with elevated D-dimer levels, which were significantly higher than in the control group (p=0.000). The median D-dimer in influenza patients was 4.9 times higher than controls. Patients with pre-existing cardiovascular disease had 2.5-fold higher D-dimer levels compared to those without (p=0.02). Influenza patients with pneumonia showed 3.8-fold higher median D-dimer levels versus those without pneumonia (p=0.0009). Non-survivors had 2.8-fold higher admission D-dimer levels than survivors (p=0.003). A D-dimer level &gt;3000 ng/mL in influenza-associated pneumonia correlated with high mortality risk (p&lt;0.05). Conclusion. Patients with influenza complicated by pneumonia exhibit elevated D-dimer levels, creating a prothrombotic state that predisposes to thrombotic complications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>грипп</kwd><kwd>пневмония</kwd><kwd>гемостаз</kwd><kwd>Д-димер</kwd></kwd-group><kwd-group xml:lang="en"><kwd>influenza</kwd><kwd>pneumonia</kwd><kwd>hemostasis</kwd><kwd>D-dimer</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет гранта Академии наук Республики Татарстан, предоставленного молодым ученым и молодежным научным коллективам на проведение научных исследований в наиболее перспективных и значимых для развития Республики Татарстан областях в 2024 г.</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">Lemaitre M., Carrat F.
