В последнее время большие надежды возлагаются на внедрение в практику результатов исследований, основанных на определении биологических маркеров воспаления, одним из которых является фекальный кальпротектин (ФК). В литературе имеются единичные сообщения по результатам определения ФК у больных с целиакией, причем полученные данные отличаются разнообразием показателей.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: определить клиническую значимость фекального кальпротектина при целиакии у детей, провести параллели между ФК и нарушением проницаемости тонкого кишечника.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В период с января 2018 г. по июнь 2019 г. обследовано 42 ребенка: 28 с впервые выявленной целиакией, 14 больных с ранее установленным диагнозом, соблюдавших аглютеновую диету, и 20 практически здоровых детей аналогичного возраста (контрольная группа). Всем детям проводилось определение антител к тканевой трансглутаминазе IgA и общего IgA (ИФА-метод). Измерение уровня ФК проводилось ИФА-методом. Использовался и неинвазивный способ определения проницаемости кишечной стенки (по методу В.И. Петрова и соавт., 2003 год).</p></sec><sec><title>Результаты</title><p>Результаты. Исследования ФК продемонстрировали повышение его значений у детей с впервые установленным диагнозом — 36,6 ± 10,2 мкг/г по сравнению с контрольной группой (20,9 ± 8,7 мкг/г). В группе детей с рефрактерным течением заболевания показатели ФК были значительно выше, чем в группе до лечения и в контрольной группе: 77,9 ± 24 мкг/г. Результаты оценки состояния кишечного барьера показали, что у пациентов с целиакией отмечалось повышение проницаемости кишечной стенки по сравнению с контрольной группой из здоровых детей (0,3 ± 0,02 опт ед., p &lt; 0,05), наиболее заметное при впервые установленной целиакией (-0,1 ± 0,05 опт ед.). Корреляционный анализ продемонстрировал прямую взаимосвязь между значениями ФК и проницаемостью тонкой кишки при рефрактерной целиакии (0,96).</p></sec><sec><title>Заключение</title><p>Заключение. У детей с рефрактерным течением целиакии показатели ФК превышают значения здоровых детей и пациентов с первично диагностированным заболеванием. Выявлена высокая корреляционная связь между повышенными значениями ФК и проницаемостью кишечника у детей с рефрактерным течением заболевания.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. A promising research avenue in recent years has been implementing research findings on biological markers of inflammation into clinical practice. One such marker is fecal calprotectin. The literature contains only isolated reports on fecal calprotectin concentrations in patients with celiac disease, and the available data vary significantly.</p></sec><sec><title>Objective</title><p>Objective. To determine the clinical significance of fecal calprotectin in pediatric celiac disease and to find its relationship with small bowel permeability.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. From January 2018 to June 2019, 42 pediatric patients were examined: 28 with newly diagnosed celiac disease, 14 previously diagnosed children adhering to a gluten-free diet, and 20 apparently healthy, age-matched control subjects. All participants were tested for IgA tissue transglutaminase antibodies and for total IgA (ELISA). Fecal calprotectin levels were also measured using ELISA. Intestinal permeability was assessed using a non-invasive method (after Petrov V.I. et al., 2003).</p></sec><sec><title>Results</title><p>Results. Fecal calprotectin levels were elevated in newly diagnosed celiac patients (36.6 ± 10.2 мcg/g) compared with the control group (20.9 ± 8.7 мcg/g). In children with refractory celiac disease, fecal calprotectin levels were significantly higher than in both the newly diagnosed group and controls (77.9 ± 24 мcg/g). Assessment of the intestinal barrier showed increased intestinal permeability in celiac patients compared with healthy controls (0.3 ± 0.02 optical units, p &lt; 0.05), with the most pronounced changes observed in newly diagnosed patients (–0.1 ± 0.05 optical units). Correlation analysis revealed a strong positive relationship between fecal calprotectin levels and small bowel permeability in refractory celiac disease (r = 0.96).</p></sec><sec><title>Conclusion</title><p>Conclusion. In children with refractory celiac disease, fecal calprotectin levels exceed those of both healthy controls and newly diagnosed patients. A strong correlation was identified between elevated fecal calprotectin values and increased intestinal permeability in children with refractory celiac disease.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>целиакия</kwd><kwd>фекальный кальпротектин</kwd><kwd>кишечный барьер</kwd><kwd>воспаление</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>celiac disease</kwd><kwd>fecal calprotectin</kwd><kwd>intestinal barrier</kwd><kwd>inflammation</kwd><kwd>children</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Статья выполнена в рамках прикладного научного проекта при Министерстве здравоохранения Республики Узбекистан «Разработка дифференцированных методов лечения синдрома мальабсорбции у детей на основе оценки состояния проницаемости кишечного барьера».
