Поставленная цель предполагала изучение пациентов с COVID-19 и без такового.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Сплошная случайная выборка состояла из 253 больных с антибиотик-ассоциированной диареей. Использовались стандартные, рекомендованные международными и российскими соглашениями методы ультразвукового исследования (УЗИ) кишечной стенки, а также диагностики инфекции SARS-CoV-2 и Cl. difficile.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что при антибиотик-ассоциированной диарее распространенное утолщение кишечной стенки величиной более 3,2 мм по данным УЗИ наблюдается при энтероколите, вызванном Cl. difficile. При диарее у пациентов с COVID-19 обнаружение кишечной стенки толщиной более 4,0 мм указывает на наличие псевдомембранозного колита при исключении патологии кишечника ишемического генеза. Тяжелое течение клостридиального энтероколита при эхографии характеризуется распространенным увеличением толщины толстокишечной стенки с максимальным значением более 7,2 мм. Кроме того, возможны дополнительные ультразвуковые признаки тяжелого течения энтероколита, вызванного Cl. difficile: наличие паракольной свободной жидкости и/или асцитической жидкости в различных областях брюшной полости; повышение эхогенности прилегающей к воспаленной кишке жировой ткани (сальника) и “увеличение” ее объема; нарушение стратификации стенки толстой кишки; утолщение стенки тонкой кишки более 3,0 мм; парез толстой кишки; токсический мегаколон. Сохранение у пациентов с энтероколитом, вызванным Cl. difficile, утолщения кишечной стенки более 6,0 мм по результатам УЗИ после проведения стандартного курса лечения с достижением клинического целевого результата (отсутствие диареи, нормализация температуры тела и лабораторных показателей) является предиктором рецидива заболевания. При сочетании энтероколита, вызванного Cl. difficile, с COVID-19 можно использовать вышеописанные ультразвуковые диагностические критерии псевдомембранозного колита при установлении его тяжелого течения и высокой вероятности рецидива.</p></sec><sec><title>Заключение</title><p>Заключение. Использование УЗИ кишечной стенки и окружающих структур позволяет детализировать диагностику энтероколита, вызванного Cl. difficile.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study: to determine ultrasound signs of severe course and prognostic criteria for recurrence of Clostridioides difficile (Cl. difficile) colitis and the possibility of separating clinically negligible antibiotic-associated diarrhea from its case related with Clostridial infection. In order to fulfill the aim the study involved patients with and without COVID-19.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. A continuous random sample consisted of 253 patients with antibiotic-associated diarrhea. We used standard, recommended by international and Russian agreements methods of the intestinal wall ultrasound examination and diagnostics of SARS-CoV-2 and Cl. difficile infection.</p></sec><sec><title>Results</title><p>Results. It was found that in antibiotic-associated diarrhea widespread intestinal wall thickening greater than 3.2 mm by ultrasonography is observed in Cl. difficile colitis. In case of diarrhea in patients with COVID-19, the detection of intestinal wall thickness of more than 4.0 mm indicates the presence of pseudomembranous colitis when intestinal pathology of ischemic genesis is excluded. Severe course of Сlostridial colitis is characterized by widespread increase in the colonic wall thickness with a maximum value of more than 7.2 mm at echography. Furthermore, there may be additional ultrasound signs of severe course of Cl. difficile colitis: the presence of paracolic free fluid and/or ascitic fluid in various regions of the abdominal cavity; increased echogenicity of adipose tissue adjacent to the inflamed intestine (omentum) and “increase” in its volume; impaired stratification of the colonic wall; thickening of the small intestine wall more than 3.0 mm; paresis of the colon; toxic megacolon. When thickening of the intestinal wall detected by ultrasound in patients with Cl. difficile colitis is more than 6.0 mm after the standard course of treatment with the achievement of clinical target results (absence of diarrhea, normalization of temperature and laboratory parameters) it is a predictor of recurrence of the disease. The described ultrasound diagnostic criteria for pseudomembranous colitis can be used for establishing its severe course and high probability of recurrence in the case of the combination of Cl. difficile colitis with COVID-19.</p></sec><sec><title>Conclusion</title><p>Conclusion: the use of ultrasound examination of the intestinal wall and surrounding structures allows to detail the diagnosis of Cl. difficile colitis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ультразвуковая диагностика</kwd><kwd>Clostridioides difficile</kwd><kwd>псевдомембранозный колит</kwd><kwd>антибиотик-ассоциированная диарея</kwd><kwd>рецидив</kwd><kwd>ободочная кишка</kwd><kwd>COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ultrasound</kwd><kwd>Clostridioides difficile</kwd><kwd>pseudomembranous colitis</kwd><kwd>antibiotic-associated diarrhea</kwd><kwd>recurrence</kwd><kwd>colon</kwd><kwd>COVID-19</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">Palestro C.J., Brandon D.C., Dibble E.H. et al.
