Ингибиторы провоспалительного цитокина фактора некроза опухоли (ФНО) — искусственно синтезированные молекулы, способные ингибировать активность ФНО и тем самым влиять на симптомы ряда заболеваний. Способность ингибировать ФНО имеют моноклональные антитела, такие как инфликсимаб и адалимумаб, а также гибридные белки, например, этанерцепт. Показана эффективность применения блокаторов ФНО у пациентов с воспалительными заболеваниями кишечника (ВЗК). Однако 20–40% больных ВЗК не отвечают на индукционную терапию, а у 10–30% пациентов наблюдается потеря эффекта к 1 году терапии.</p></sec><sec><title>Цель работы</title><p>Цель работы: определить информативность терапевтического лекарственного мониторинга (ТЛМ) для оптимизации лечения блокаторами ФНО инфликсимабом (IFX) и адалимумабом (ADA) у детей с ВЗК.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Под наблюдением находились 140 больных ВЗК в возрасте 3,4–18,0 лет. Их них 74 ребёнка получали лечение IFX; 66 — ADA. Остаточный уровень IFХ и ADA в сыворотке крови определяли с помощью иммуноферментного анализа. Различия между группами оценивали с помощью непараметрического U-критерия Манна–Уитни.</p></sec><sec><title>Результаты</title><p>Результаты. Уровни IFX менее 3 мкг/мл были выявлены в 64% случаев, ADA менее 5 мкг/мл — в 46%. Остаточные концентрации IFX и ADA в крови больных в состоянии ремиссии существенно превышали их уровни в крови детей при обострении ВЗК. Выявлена значимая обратная зависимость между остаточным уровнем IFX (r = –0,68, p = 0,000) и ADA (r = –0,31, p = 0,000) и числом дней после введения препаратов. Антитела к IFХ были обнаружены у 27,3% больных с обострением, и у 5,8% в ремиссии (p &lt; 0,001). Антитела к ADA у детей с ВЗК обнаружены у 4 пациентов с низкой концентрацией препарата (2,57 ± 0,45 мкг/мл) в сыворотке крови в состоянии обострения. Установлено, что у больных на анти-ФНО-терапии при эмпирическом подборе дозы остаточный уровень ниже, чем у детей, которым коррекция дозы проводилась с учётом остаточной концентрации препаратов.</p></sec><sec><title>Заключение</title><p>Заключение. Использование ТЛМ блокаторов ФНО в сочетании с определением антител к препаратам позволяет существенно увеличить эффективность терапии детей с ВЗК. </p></sec><sec><title>Участие авторов</title><p>Участие авторов:Радыгина Т.В., Илларионов А.С., Петричук С.В., Потапов А.С. — концепция и дизайн исследования;Радыгина Т.В., Илларионов А.С., Купцова Д.Г., Семикина Е.Л., Анушенко А.О., Курбатова О.В. — сбор и обработка материала;Радыгина Т.В. — написание текста;Потапов А.С., Фисенко А.П. — редактирование.Все соавторы — утверждение окончательного варианта статьи, ответственность за целостность всех частей статьи. </p></sec><sec><title>Финансирование</title><p>Финансирование.

The effectiveness of the use of TNF inhibitors in patients with inflammatory bowel diseases (IBD) has been shown. 20–40% of patients are known to fail to respond to received therapy, and 10–30% of patients experience a loss of effect by the year of therapy. Objective is to evaluate the information content of therapeutic drug monitoring (TDM) for effective treatment with TNF blockers (infliximab — IFX, adalimumab — ADA) in IBD children.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. There were examined seventy four children on IFX therapy including 66 children on ADA therapy. The age of the children ranged from 3.4 to 18 years. Residual levels of IHF and ADA were determined using a lateral flow immunoassay. Statistical data processing was performed using the Statistica 10.0, SPSS 16 software. Differences between groups were assessed using the nonparametric Mann–Whitney U test.</p></sec><sec><title>Results</title><p>Results. IFX levels (less than 3 µg/ml) were detected in 64% of cases, ADA (less than 5 µg/ml) in 21% of cases. The residual level of IFX and ADA in remission significantly exceeded the level of drugs in groups of children in exacerbation. An inverse relationship was observed between the residual level of IFX (r = –0.68, p = 0.000) and ADA (r = –0.31, p = 0.000) and the number of days after drug administration. Anti-IFX antibodies were found in 27.3% in the exacerbation group and in 5.8% in remission (p &lt; 0.001). Antibodies to ADA in children with IBD were found in 4 patients with a low concentration of the drug (2.57 ± 0.45 µg/ml) in the serum in a state of exacerbation. In patients on anti-TNF therapy, empirical dose selection revealed a residual level lower than in children in whom dose adjustment was carried out taking into account the residual concentration of drugs.</p></sec><sec><title>Conclusion</title><p>Conclusion. The use of TDM TNF blockers in combination with the determination of antibodies to drugs can significantly increase the effectiveness of therapy in IBD children.</p></sec><sec><title>Contribution</title><p>Contribution:Radygina T.V., Illarionov A.S., Petrichuk S.V. — research concept and design of the study;Radygina T.V., Illarionov A.S., Petrichuk S.V., Kuptsova D.G., Potapov A.S., Anushenko A.O., Kurbatova O.V. — collection and processing of material;Radygina T.V. — text writing;Potapov A.S., Fisenko A.P. — editing.All co-authors — approval of the final version of the article, responsibility for the integrity of all parts of the article.</p></sec><sec><title>Ethics approval</title><p>Ethics approval.
