One of the target organs of the SARS-CoV-2 virus is the intestine. The pathogenesis of intestinal damage in a new coronavirus infection remains unclear and requires further in-depth study. Possible mechanisms include a direct cytotoxic effect of the virus, a persistent reduction in butyrate-producing bacteria, side effects of drugs, <italic>Clostridioides difficile </italic>infection, microvascular thrombosis, and the immune-mediated inflammatory reactions in the intestine. The most common symptom of intestinal damage during coronavirus infection, both in the acute phase and in the post-COVID period, is diarrhea. The impact of many aggressive factors on the intestines can form both long-term functional disorders and be the cause of the onset of organic diseases. Treatment should be aimed at possible causes of intestinal damage (<italic>Clostridioides difficile</italic>), as well as reducing inflammation, restoring intestinal permeability, cytoprotection of mucosal cells, replenishing butyric acid deficiency. When choosing a therapy for intestinal disorders, preference should be given to drugs with a pleiotropic effect in order to influence various possible pathogenetic mechanisms.</p></abstract><trans-abstract xml:lang="ru"><p>Инфекция COVID-19 может проявляться поражением органов желудочно-кишечного тракта у 25% пациентов. Одним из органов-мишеней вируса SARS-CoV-2 является кишечник. Патогенез повреждения кишечника при новой коронавирусной инфекции остается неясным и требует дальнейшего глубокого изучения. Возможными механизмами являются прямое цитотоксическое действие вируса, стойкое снижение бутиратпродуцирующих бактерий, побочные эффекты лекарственных препаратов, развитие инфекции <italic>Clostridioides difficile</italic>, микроваскулярный тромбоз и развитие иммуноопосредованных воспалительных реакций в кишечнике. Наиболее частым симптомом поражения кишечника при коронавирусной инфекции как в острой фазе, так и в постковидный период является диарея. Воздействие множества агрессивных факторов на кишечник может как формировать длительные функциональные расстройства, так и являться причиной дебюта органических заболеваний. Лечение должно быть направлено на возможные причины поражения кишечника (<italic>Clostridioides difficile</italic>), а также уменьшение воспаления, восстановление кишечной проницаемости, цитопротекцию клеток слизистой оболочки, восполнение дефицита масляной кислоты. При выборе терапии нарушений кишечника следует отдавать предпочтение препаратам с плейотропным действием с целью воздействия на различные возможные патогенетические механизмы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>СOVID-19</kwd><kwd>gastrointestinal symptoms</kwd><kwd>diarrhea</kwd><kwd>microbiocenosis</kwd><kwd>intestines</kwd><kwd>psyllium</kwd><kwd>butyrate</kwd><kwd>mesalazine</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>СOVID-19</kwd><kwd>гастроинтестинальные симптомы</kwd><kwd>диарея</kwd><kwd>микробиоценоз</kwd><kwd>кишечник</kwd><kwd>псиллиум</kwd><kwd>бутират</kwd><kwd>месалазин</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ивашкин В.Т., Шептулин А.А., Зольникова О.Ю., и др.
