Особым свойством вируса SARS-CoV-2 является  тропность к эндотелию сосудов с развитием эндотелиита, что влечет за собой ряд характерных нарушений  свертывающей системы крови: коагулопатии с повышенным  образованием тромбина, D-димера, сниженным фибринолизом и удлиненным протромбиновым  временем. Нарушение коагуляции при  COVID-19 получило название тромбовоспаления. В  патогенезе гиперкоагуляции при COVID-19 играют роль гипервоспаление, повышенное содержание в крови фактора Виллебранда, фактора VIII, нейтрофильных внеклеточных ловушек, активация тромбоцитов,  микровезикулы. На сегодняшний день известно, что случаи  COVID-19 у детей и подростков составляют небольшую часть от общего числа пациентов с диагностированными  клиническими случаями COVID-19, а нарушения системы гемостаза сходны с таковыми у взрослых. Степень гиперкоагуляционного синдрома и риск тромбоза  зависят от тяжести COVID-19, и у детей наиболее выражены при  развитии гипервоспалительного иммунного ответа, получившего название мультисистемный воспалительный  синдром. При этом продолжается изучение механизмов  патогенеза COVID-19 у взрослых и детей, в том числе нарушений системы гемостаза, и поиск оптимальных методов  терапии тромбовоспаления, лежащего в основе патогенеза COVID-19. </p></abstract><trans-abstract xml:lang="en"><p> The pandemic of the new coronavirus infection COVID-19 in 2020 has become the main health problem across the globe. A special characteristic of the SARSCoV-2 virus is tropism to the vascular endothelium with the  development of endotheliitis, which entails a number of typical disorders of the blood coagulation system: coagulopathy with increased thrombin generation, D-dimer, decreased fibrinolysis and prolonged prothrombin time. The coagulation disorder in COVID-19 is called thromboinflammation. Hyperinflammation, increased blood levels of von Willebrand factor, coagulation factor VIII, neutrophil extracellular traps, platelet activation, microvesicles play a significant role in the pathogenesis of hypercoagulation in COVID-19. To date, it is known that cases of COVID-19 in children and adolescents constitute a small part of the total number of patients with diagnosed COVID-19, and disorders of the blood coagulation system are similar to those in adults. The degree of hypercoagulable syndrome and the risk of thrombosis depend on the severity of COVID-19. And for children they are most expressed with the development of a hyperinflammatory immune response, called multisystem inflammatory syndrome. At the same time, clinical studies of the pathogenesis of COVID-19 in adults and children and the search for optimal methods of therapy for thrombus inflammation, which underlies the pathogenesis of COVID-19, continue. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>дети</kwd><kwd>гемостаз</kwd><kwd>коагулопатия</kwd><kwd>антикоагулянты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>сhildren</kwd><kwd>hemostasis</kwd><kwd>coagulopathy</kwd><kwd>anticoagulants</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">ProMED International Society for Infectious Diseases.
