Проведено комплексное обследование 70 детей с ВЗК в возрасте от 12 до 18 лет в динамике заболевания на фоне проводимого лечения (49 детей с БК, 21 ребенок с ЯК). Группу сравнения составили 50 практически здоровых детей аналогичного возраста, прошедших комплексное профилактическое обследование. В зависимости от терапевтического ответа к году применения биологической терапии, пациенты были разделены на две группы – со стойким положительным эффектом препарата и с нестабильным эффектом терапии. Определяли содержание основных и малых популяций лимфоцитов периферической крови до первого введения инфликсимаба. Иммунофенотипирование проводили методом многоцветной проточной цитофлуориметрии (FC 500) с использованием маркеров CD45, CD3, CD4, CD8, CD19, CD16, CD56, HLA-DR, CD5, CD161, CD127, CD25, CD294.Получено: содержание В-лимфоцитов было достоверно снижено у детей с нестабильным эффектом терапии, у детей со стойким положительным эффектом уровень В-лимфоцитов не отличался от группы сравнения. Анализ состава В-лимфоцитов показал дисбаланс в соотношении В1и В2-клеток с уменьшением содержания В1-клеток у пациентов с ВЗК относительно группы сравнения. При этом у пациентов с нестабильным эффектом выявлено значимое снижение популяции В2-клеток относительно группы сравнения и относительно группы со стойким эффектом. Количество NK-клеток у пациентов с ВЗК было снижено относительно группы сравнения. Оценка содержания субпопуляций Т-лимфоцитов выявила ряд особенностей у пациентов с минимальным терапевтическим эффектом – увеличение уровня активированных Т-хелперов (CD4+CD25+CD127high) и Th17-лимфоцитов CD3+CD4+CD161+) относительно детей со стойким эффектом терапии и группы сравнения. Кроме того, у детей с минимальным эффектом терапии уровень Treg в составе Т-хелперов оказался достоверно выше, чем в группе сравнения. Проведенный ROC-анализ выявил наиболее информативные показатели для групп с минимальным и стойким эффектом терапии и показал хорошее качество разделительной модели для относительного количества Th17-лимфоцитов, активированных Т-хелперов и В-лимфоцитов. Количество Тh17-лимфоцитов (% от CD3+CD4+лимфоцитов) с высокой долей вероятности позволяет прогнозировать эффект терапии блокатором TNFα. Проведенные исследования позволяют рекомендовать включение оценки состояния клеточного иммунитета в мониторинг состояния пациентов с ВЗК.</p></abstract><trans-abstract xml:lang="en"><p>(IBD), who were for the first time treated with TNFα blocker (infliximab). Our aim was to determine prognostic informative value of the immunological parameters in order to assess the treatment efficiency. A comprehensive research included seventy children with IBD from 12 to 18 years old in the course of specific treatment (49 children with CD, 21 children with UC).</p><p>The comparison group consisted of fifty healthy children of similar age who were subjected to a similar detailed examination. The patients were divided into two groups, depending on their therapeutic response following 1 year of biological therapy: the first group showed a persistent positive effect of the drug, and the second group exhibited only unstable effects of the treatment. We determined the contents of major and small subpopulations of peripheral blood lymphocytes before the first administration of infliximab. Immunophenotyping was performed by multicolor flow cytometry (FC 500), using the CD45, CD3, CD4, CD8, CD19, CD16, CD56, HLA-DR, CD5, CD161, CD127, CD25, and CD294 markers.</p><p>We have revealed that the content of B lymphocytes was significantly reduced in children with unstable effects of therapy. By contrast, the B lymphocyte levels in children with persistent positive therapeutic effect did not differ from the comparison group. Analysis of the composition of the B lymphocyte profile showed an imbalance in the B1-to-B2 cell ratio, with decreased of B1 cell counts in IBD patients against the comparison group. In addition, the patients with unstable therapeutic effect showed a significant decrease in B2 cell numbers compared with a group with persistent effect and comparison group. The numbers of NK cells in IBD patients were found to be reduced against the comparison group. Assessment of T lymphocytes subsets revealed a number of features in the patients with minimal therapeutic effects, i.e., an increased level of activated T helper cells (CD4+CD25+CD127high) and Th17 lymphocytes (CD3+CD4+CD161+), as compared to children with stable effect of treatment and to the comparison group. Moreover, in children with minimal effects of therapy, the levels of Tregs within T-helper cell subsets were significantly higher than in the comparison group. By means of ROC analysis, we have identified most informative parameters for the groups with minimal versus persistent therapeutic effect, and showed a good quality for a discrimination model involving relative amount of Th17 cells, activated T helper cells and B lymphocytes. The number of Тh17 lymphocytes (% CD3+CD4+ lymphocytes) allowed to predict the effect of therapy with a TNFα blocker with high probability. The present study enables us to propose cellular immunity testing, as a promising tool for monitoring clinical state of IBD patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>популяции лимфоцитов</kwd><kwd>популяции CD4+ лимфоцитов</kwd><kwd>ВЗК</kwd><kwd>дети</kwd><kwd>инфликсимаб</kwd><kwd>эффективность терапии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>We have performed a study of blood lymphocyte subsets in children with inflammatory bowel disease</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">Белоусова Е.А., Морозова Н.А., Великанов Е.В., Гаганов Л.Е..
