Показана возможность непосредственного взаимодействия коронавируса с рецепторами ангиотензинпревращающего фермента-2 (АПФ-2) слизистой оболочки желудочно-кишечного тракта (ЖКТ) с развитием ее повреждения и последующего кровотечения. Значение антикоагулянтной терапии как фактора риска возникновения ЖКК оценивается противоречиво. У большинства больных с инфекцией COVID-19 и ЖКК консервативная гемостатическая терапия оказывается эффективной. Влияние ЖКК на течение и прогноз новой коронавирусной инфекции имеет неоднозначную трактовку. Учитывая недостаточную изученность патогенетических и клинических аспектов ЖКК у больных с инфекцией COVID-19, эта проблема требует дальнейших исследований.</p></abstract><trans-abstract xml:lang="en"><p>The article discusses the pathogenetic and clinical aspects of gastrointestinal bleeding (GIB) in patients with a novel coronavirus infection (COVID-19). The possibility of direct interaction of the coronavirus with the receptors of the angiotensinconverting enzyme 2 (ACE-2) of the mucous membrane of the gastrointestinal tract with the development of its damage and subsequent bleeding has been shown. The value of anticoagulant therapy as a risk factor for the occurrence of GIB is evaluated inconsistently. In most patients with COVID-19 infection and GIB conservative hemostatic therapy is eff ective. The infl uence of GIB on the course and prognosis of a novel coronavirus infection has an contradictory interpretation. Given the lack of knowledge of the pathogenetic and clinical aspects of GIB in patients with COVID-19 infection, this problem requires further research.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>новая коронавирусная инфекция</kwd><kwd>желудочно-кишечные кровотечения</kwd><kwd>причины</kwd><kwd>факторы риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>novel coronavirus infection</kwd><kwd>gastrointestinal bleeding</kwd><kwd>causes</kwd><kwd>risk factors</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">Mauro A., De Grazua F., Lenti M.V., Penagini R., Frego R., Ardizzone S. et al.
