Обследовано 370 детей (198 мальчиков, 172 девочки) в возрасте 5–18 лет с воспалительными заболеваниями кишечника. Определяли лейкоцитарные показатели крови, концентрацию С-реактивного белка (СРБ), скорость оседания эритроцитов (СОЭ), содержание фекального кальпротектина (ФК). Изменения клинической активности БК и ЯК у детей устанавливали с помощью педиатрических индексов активности: PCDAI и PUCAI соответственно. Анализ эндоскопической активности у 160 больных с БК и ЯК проводили по шкалам SES-CD и UCEIS соответственно.</p></sec><sec><title>Результаты</title><p>Результаты. При повышении клинической активности БК у детей абсолютные уровни лейкоцитов, лимфоцитов и моноцитов существенно не изменялись, при этом значимо повышалась реактивность нейтрофилов. У больных с высокой эндоскопической активностью БК выявлено увеличение абсолютного числа моноцитов и реактивности нейтрофилов. У больных с высокой клинической активностью ЯК установлено увеличение количества лейкоцитов и абсолютного числа нейтрофилов. При этом увеличивались гранулярность и реактивность нейтрофилов от ремиссии до умеренной и высокой клинической активности ЯК. У детей с высокой эндоскопической активностью ЯК увеличивались число лейкоцитов, абсолютное количество нейтрофилов и моноцитов. При этом существенно повышалась гранулярность нейтрофилов по мере нарастания эндоскопической активности ЯК от ремиссии к умеренной активности. Лейкоцитарные показатели больных ЯК умеренно коррелировали с уровнями ФК, а абсолютное число нейтрофилов было тесно связано с его содержанием. Гранулярность и реактивность нейтрофилов положительно коррелировали с уровнями СОЭ и СРБ у детей с БК и концентрациями СРБ у детей с ЯК.</p></sec><sec><title>Заключение</title><p>Заключение. Установленные закономерности изменений количественного состава лейкоцитов и их функциональных свойств (реактивности и гранулярности) непосредственно определяются различной активностью воспалительных заболеваний кишечника у детей и имеют диагностическое значение.</p></sec><sec><title>Участие авторов</title><p>Участие авторов: Семикина Е.Л., Цветкова В.С., Потапов А.С. — концепция и дизайн исследования; Цветкова В.С., Сурков А.Н., Лохматов М.М., Копыльцова Е.А., Акулова С.С., Вершинина М.Г. — сбор и обработка материала; Цветкова В.С., Семикина Е.Л. — статистическая обработка, написание текста; Фисенко А.П., Семикина Е.Л., Потапов А.С. — редактирование.

Leukocytic blood parameters, concentrations of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), faecal calprotectin (FC) levels were determined. Changes in clinical activity in Crohn’s disease (CD) and ulcerative colitis (UC) cases were determined using pediatric activity indices: PCDAI and PUCAI, respectively. Analysis of endoscopic activity in 160 CD and UC patients was determined using the scales: SES-CD and UCEIS, respectively.</p></sec><sec><title>Results</title><p>Results. It was found that with an increase in the clinical activity of CD in children, the absolute numbers of leukocytes, lymphocytes and monocytes did not change significantly. In contrast, a significant increase in neutrophil reactivity was noted. In patients with high endoscopic CD activity an increase in the absolute number of monocytes and neutrophil reactivity was found. In patients with high clinical activity of UC, an increase in the number of leukocytes and the absolute number of neutrophils was found. At the same time, the granularity and reactivity of neutrophils increased from remission to moderate and high clinical activity of UC. In children with high endoscopic UC activity, the number of leukocytes, the absolute number of neutrophils and monocytes increased. At the same time, the granularity of neutrophils significantly increased as the endoscopic activity of UC increased from remission to moderate activity. Leukocyte parameters in UC patients correlated moderately with FC level, and the absolute number of neutrophils was closely related to its content. The granularity and reactivity of neutrophils positively correlated with ESR and CRP levels in children with CD and CRP concentrations in children with UC.</p></sec><sec><title>Conclusion</title><p>Conclusion. The established patterns of changes in the quantitative composition of leukocytes and their functional properties (reactivity and granularity) are directly determined by the different activity of IBD in children and have diagnostic value.</p></sec><sec><title>Contribution</title><p>Contribution: Semikina E.L., Tsvetkova V.S., Potapov A.S. — research concept and design; Tsvetkova V.S., Surkov A.N., Lokhmatov M.M., Kopyltsova E.A., Akulova S.S. — collection and processing of material; Tsvetkova V.S., Semikina E.L. — statistical processing; Tsvetkova V.S., Semikina E.L. — text writing; Fisenko A.P., Semikina E.L., Potapov A.S. — editing.
