Одним из осложнений новой коронавирусной инфекции (COVID-19) является развитие венозных тромбоэмболических осложнений. В этой связи интерес представляют изменения системы гемостаза, сохраняющиеся в процессе выздоровления у больных, перенесших заболевание в легкой форме.</p></sec><sec><title>   Цель</title><p>   Цель: оценить состояние системы гемостаза у больных, перенесших новую коронавирусную инфекцию легкой степени тяжести.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы. Обследованы 39 человек, перенесших COVID-19 легкой степени тяжести. Определяли следующие плазменные параметры системы гемостаза: индекс активированного парциального тромбопластинового времени (АПТВ), протромбин по Квику, концентрацию фибриногена, активность фактора VIII, антитромбина III,протеина C, концентрации протеина S и D-димера, ристоцетин-кофакторную активность и концентрацию антигена фактора фон Виллебранда. Выполняли тест генерации тромбина.</p></sec><sec><title>   Результаты</title><p>   Результаты. У лиц, перенесших COVID-19, в сравнении со здоровыми лицами было выявлено увеличение в плазме концентрации фибриногена, антигена фактора фон Виллебранда, D-димера, повышение активностиантитромбина III, снижение чувствительности к тромбомодулину, повышение индекса коагуляции.</p></sec><sec><title>   Заключение</title><p>   Заключение. Для больных, перенесших COVID-19, характерна прокоагулянтная направленность изменений плазменного гемостаза, сохраняющихся до 3-х месяцев после перенесенного заболевания. Необходимо учитывать состояние системы гемостаза даже у больных, перенесших COVID-19 в легкой форме.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Introduction</title><p>   Introduction. One of the complications of the new coronavirus infection (COVID-19) is the development of venous thromboembolic complications. In this regard, changes in the hemostasis system that persist in the process of recovery in patients who have had a mild form of the disease are of interest.Aim. To evaluate plasma hemostasis in patients after mild coronavirus infection</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. 39 patients after mild coronavirus infection were examined. The following parameters were assessed: APTT, PT, fibrinogen, factor VIII, von Willebrand factor, D-dimer, proteins C and S, and thrombin generation.</p></sec><sec><title>   Results</title><p>   Results. In patients who underwent COVID-19, in comparison with healthy individuals, an increase in the plasma concentration of fibrinogen, von Willebrand factor antigen, and D-dimer was detected. Furthermore, increased activity of antithrombin III, decreased sensitivity to thrombomodulin, and an increase in the coagulation index were detected.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. Patients who have undergone COVID-19 are characterized by a procoagulant orientation of changes in plasma hemostasis that persist up to 3 months after the disease. It is necessary to take into account the state of the hemostasis system even in patients who have undergone COVID-19 in mild form.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гемостаз</kwd><kwd>COVID-19</kwd><kwd>генерация тромбина</kwd><kwd>антикоагулянты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hemostasis</kwd><kwd>COVID-19</kwd><kwd>thrombin generation</kwd><kwd>anticoagulants</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">This study had no sponsorship</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">Nicolai L., Leunig.
