Воспалительная активность при язвенном колите (ЯК) и болезни Крона (БК) оценивается комплексно на основании эндоскопических, клинических и лабораторных данных. Контактная ранимость (КР) слизистой оболочки кишки (СОК), верифицируемая при колоноскопии, является индикатором заживления СОК — цели лечения при воспалительных заболеваниях кишечника (ВЗК) и значимым прогностическим фактором клинического течения ЯК.</p></sec><sec><title>Цель работы</title><p>Цель работы: определить значимость КР СОК при оценке активности ВЗК у детей.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В клиническое проспективное обсервационное когортное исследование включен 81 ребёнок с диагнозом ВЗК, из которых 42 больных составили группу с ЯК и 39 — с БК. Оценка активности этих заболеваний проводилась с использованием педиатрических индексов клинической активности ЯК и БК, а также эндоскопического индекса активности ЯК и простой эндоскопической шкалы БК. КР СОК оценивали по шкале, где 0 баллов — отсутствие патологических изменений, 1 балл — образование внутрислизистых геморрагий, 2 балла — контактная кровоточивость.</p></sec><sec><title>Результаты</title><p>Результаты. У больных ЯК выявлены тесная положительная корреляция между эндоскопической активностью болезни и выраженностью КР (p &lt; 0,001; r = 0,713) и умеренной тесноты — между клинической активностью и КР (p &lt; 0,001; r = 0,503). У детей с БК установлены положительные корреляции умеренной тесноты между эндоскопической активностью болезни и выраженностью КР (p = 0,003; r = 0,464). Однако у больных БК корреляции между клинической активностью болезни и КР незначимы (p = 0,184; r = 0,223).</p></sec><sec><title>Заключение</title><p>Заключение. Определение КР для определения заживления СОК при ВЗК является информативным методом и имеет диагностическую значимость у больных ЯК, при котором воспалительный процесс локализуется поверхностно в слизистом слое. Клиническая интерпретация КР требует обязательного сопоставления с клинико-анамнестическими данными и результатами лабораторных исследований.</p></sec><sec><title>Участие авторов</title><p>Участие авторов: Красновидова А.Е., Потапов А.С. — концепция и дизайн исследования; Красновидова А.Е., Олдаковский В.И., Дроздова А.С., Винокурова А.В. — сбор и обработка материала; Красновидова А.Е., Зенкова К.И. — статистическая обработка материала; Красновидова А.Е., Олдаковский В.И., Дроздова А.С. — написание текста; Красновидова А.Е., Потапов А.С. — редактирование.

Inflammatory activity in ulcerative colitis (UC) and Crohn’s disease (CD) is assessed comprehensively using endoscopic, clinical, and laboratory parameters. Mucosal friability (MF), verified during colonoscopy, is an indicator of mucosal healing — the therapeutic goal in inflammatory bowel disease (IBD) and a significant prognostic factor for UC clinical outcomes.</p></sec><sec><title>Aim</title><p>Aim: To evaluate the role of MF in determining IBD activity in children.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A clinical, prospective, observational cohort study included 81 IBD child, of whom 42 patients comprised the UC group and 39 the CD group. Disease activity was evaluated using pediatric clinical activity indices for UC and CD, as well as the endoscopic activity index for UC and the simple endoscopic score for CD. MF was assessed with a scale where 0 points corresponded to the absence of pathological changes, 1 point to intramucosal hemorrhages, and 2 points to contact bleeding.</p></sec><sec><title>Results</title><p>Results. In UC patients there were close positive correlations between the endoscopic activity of the disease and the severity of CD (p &lt; 0.001; r = 0.713) and a moderate closeness between clinical activity and CD (p &lt; 0.001; r = 0.503). In CD children, positive correlations of moderate crowding were found between the endoscopic activity of the disease and the severity of CD (p = 0.003; r = 0.464). However, in CD patients, the correlations between the clinical activity of the disease and CD are not significant (p = 0.184; r = 0.223).</p></sec><sec><title>Conclusion</title><p>Conclusion. The determination of the contact difference to determine the healing of the mucous membrane in IBD is an informative method and has diagnostic significance in UC patients, in which the inflammatory process is located superficially in the mucous layer. The clinical interpretation of contact vulnerability requires mandatory comparison with clinical and anamnestic data and laboratory test results.</p></sec><sec><title>Contribution</title><p>Contribution: Krasnovidova A.E., Potapov A.S. — concept and design of the study; Krasnovidova A.E., Oldakovsky V.I., Drozdova A.S., Vinokurova A.V. — collection and processing of the material; Krasnovidova A.E., Zenkova K.I. — statistical processing of the material; Krasnovidova A.E., Oldakovsky V.I., Drozdova A.S. — writing the text; Krasnovidova A.E., Potapov A.S. — editing the text.
