Провести сравнительный анализ результатов ультразвуковых исследований кишечника при COVID-19, язвенном колите (ЯК) и болезни Крона (БК) и выделить ультразвуковые критерии, наиболее специфичные для COVID-ассоциированного поражения.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для достижения поставленной цели было проведено сопоставление данных ультразвуковых исследований 50 пациентов с COVID-ассоциированным поражением кишечника (возрастной диапазон — 18‒73 года), 4 пациентов с болезнью Крона (возрастной диапазон — 18–24 года) и 4 пациентов с язвенным колитом (возрастной диапазон — 20–38 лет).</p></sec><sec><title>Результаты</title><p>Результаты. Выделен высокоспецифичный ультразвуковой критерий COVID-19-ассоциированного поражения кишечника (индекс Юдена — 1,0, AUC — 95 % ДИ (0,87‒1,0); специфичность — 95 % ДИ (85,2‒100,0)), а именно наличие мелких участков пониженной эхогенности (с волнистыми контурами) в толще слизистой оболочки и подслизистой пластинки, являющихся ультразвуковым эквивалентом зон лимфоидной инфильтрации.</p></sec><sec><title>Заключение</title><p>Заключение. Есть основания считать наличие мелких участков пониженной эхогенности (с волнистыми контурами) в толще слизистой оболочки и подслизистой пластинки ультразвуковым признаком COVID-19-ассоциированного поражения кишечника, не встречающимся при других воспалительных заболевания желудочно-кишечного тракта.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. The objective of the analysis is to conduct a comparative analysis of the results of ultrasound examinations of the intestines for COVID-19, ulcerative colitis and Crohn’s disease, and to identify ultrasound criteria that are most specific for COVID-associated lesions.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. To achieve this objective, ultrasound data from 50 patients with COVID-associated ienteropathy (age range 18-73 years), 4 patients with Crohn’s disease and 4 patients with ulcerative colitis (age range 20-38 years) were compared.</p></sec><sec><title>Results</title><p>Results. A highly specific ultrasound criterion for COVID-19-associated ienteropathy has been identified (Youden index ‒ 1.0, AUC ‒ 95% CI (0.87 ‒1.0); specificity ‒ 95% CI (85.2 ‒ 100.0)), namely: the presence of small areas of reduced echogenicity (with wavy contours) in the thickness of the mucous membrane and submucosal plate, which are the ultrasound equivalent of zones of lymphoid infiltration.</p></sec><sec><title>Conclusion</title><p>Conclusion. It is arguable that the presence of small areas of reduced echogenicity (with wavy contours) in the thickness of the mucous membrane and submucosal plate as an ultrasound sign of COVID-19-associated ienteropathy, which is not found in other inflammatory diseases of the gastrointestinal tract.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>желудочно-кишечные проявления COVID-19</kwd><kwd>ультразвуковое исследование желудочно-кишечного тракта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>astrointestinal manifestations in COVID-19</kwd><kwd>gastrointestinal ultrasound</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнялась в рамках проекта НИР «Разработать алгоритм прогнозирования пост-COVID-19-ассоциированной патологии на основании изучения клинико-лабораторных и функциональных показателей», ГПНИ 4 «Трансляционная медицина», подпрограмма 4.2 «Фундаментальные аспекты медицинской науки».
