Patients with COVID-19 develop typically two hemostasis disorders - an increased D-dimer levels and moderate thrombocytopenia, which occur in more than 40% of cases. Other hemostasis abnormalities, which are frequently reported in COVID-19, included prolonged prothrombin time (PT), also expressed as international normalized ratio, prolonged thrombin time, and activated partial thromboplastin time (APTT), which were typical acute phase reactions. Prolonged APTT or PT, and thrombocytopenia are common, especially in patients with severe clinical course. It has been hypothesized that increased D-dimer concentration and prolongation of PT, APTT are associated with higher mortality in patients with COVID-19. Disseminated intravascular coagulation occurs most often in severe cases of COVID-19 (about 2% of all hospitalized patients) and indicates a poor prognosis, i.e. about 90% mortality. It remains unclear whether SARS-CoV-2 can induce antiphospholipid antibodies. An increased incidence of positive lupus anticoagulants was observed in patients with COVID-19, it can be assumed that all patients with COVID-19 in whom antiphospholipid antibodies are revealed should be monitored and receive thromboprophylaxis even with no history of thromboembolism.</p></abstract><trans-abstract xml:lang="ru"><p>Приведен обзор основных нарушений свертывания крови при коронавирусной болезни 2019 г. (COVID-19), которая связана с несколькими гематологическими изменениями. У пациентов с COVID-19 наблюдаются два типичных нарушения гемостаза - это повышенный уровень D-димера и умеренная тромбоцитопения, которые зарегистрированы в более чем 40% случаев. Другие аномалии гемостаза, часто сообщаемые при COVID-19, включали пролонгированное протромбиновое время (ПВ), выраженное также как международное нормализованное отношение, пролонгированное тромбиновое время и активированное частичное тромбопластиновое время (АЧТВ), которые являлись типичными острофазовыми реакциями. Пролонгация АЧТВ, ПВ и тромбоцитопения встречаются часто, особенно у пациентов с тяжелым клиническим течением. Высказано предположение, что повышенная концентрация D-димера и удлинение ПВ, АЧТВ связаны с более высокой смертностью у пациентов с COVID-19. Диссеминированное внутрисосудистое свертывание крови наблюдается чаще всего в тяжелых случаях COVID-19 (около 2% всех госпитализированных пациентов) и свидетельствует о плохом прогнозе, т.е. о 90% летальности. Остается неясным, может ли SARS-CoV-2 индуцировать антифосфолипидные антитела. Повышенную частоту положительных волчаночных антикоагулянтов наблюдали у пациентов с COVID-19, можно предположить, что все пациенты с COVID-19, у которых обнаружены антифосфолипидные антитела, должны находиться под пристальным наблюдением и получать тромбопрофи-лактику даже без каких-либо тромбоэмболий в анамнезе.</p></trans-abstract><kwd-group xml:lang="en"><kwd>coronavirus infection (COVID-19)</kwd><kwd>hemostasis disorder</kwd><kwd>antiphospholipid antibodies</kwd><kwd>antiphospholipid syndrome</kwd><kwd>thrombosis</kwd><kwd>anticoagulants</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>коронавирусная инфекция (COVID-19)</kwd><kwd>нарушение гемостаза</kwd><kwd>антифосфолипидные антитела</kwd><kwd>антифосфолипидный синдром</kwd><kwd>тромбозы</kwd><kwd>антикоагулянты</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Centers for Disease Control and Prevention.
