Патофизиология псориаза также связана со снижением противовоспалительных функций иммуносупрессивных клеток. В последнее время все чаще встречаются случаи развития резистентности к проводимой терапии биопрепаратами в детском возрасте, требующие отмены препарата или его замены. Цель исследования — оценить содержание субпопуляций Т-хелперов в прогнозе эффективности биологической терапии у детей с псориазом. Иммунофенотипирование популяций Т-хелперов периферической крови проводили у 110 детей с вульгарным псориазом до назначения биологической терапии, на 16-й и 52-й неделе лечения. Возраст детей составил от 6 до 18 лет. Тяжесть псориаза и эффективность терапии оценивали по индексу PASI, который изменялся от 0 до 68 баллов. Методом проточной цитометрии определяли содержание Т-хелперов, регуляторных Т-клеток (Treg), активированных Т-хелперов (Thact) и ТЬ17-лимфоцитов. В группе пациентов с хорошим эффектом биологической терапии получено значимое снижение PASI, как на 16-й неделе терапии (p = 0,000), так и к году лечения (р = 0,017). У детей с псориазом, не зависимо от длительности и эффективности биопрепаратов, был увеличен процент Thact относительно нормативных значений. В группе 1 до назначения биологической терапии был увеличен процент Thact (р = 0,005) и Th17 (р = 0,001). Анализ динамики содержания популяций Т-хелперов в течение года биологической терапии у детей с разной эффективностью лечения показал, что наиболее значимые изменения выявлены в содержании Th17 и Treg, а также их отношения Th17/Treg. ROC-анализ показал, что при отклонении Th17 выше 53%, Thact выше 181% и Th17/Treg выше 2,6 до назначения биопрепаратов в 75% случаев можно ожидать недостаточную эффективность терапии к году. К окончанию индукционного курса при отклонении Th17 выше 102% и отношении Th17/Treg выше 2,6 вероятность неэффективного лечения составляет уже 82%. В исследовании показана информативность оценки Thact до назначения биологической терапии, динамика Th17 к концу индукционного курса и Treg после 16 недель терапии в прогнозе эффективности ГИБП у детей с псориазом.</p></abstract><trans-abstract xml:lang="en"><p>Psoriasis is a chronic inflammatory skin disease characterized by increased proliferation of epidermal cells, impaired keratinization and an inflammatory reaction in dermis caused by activation of T lymphocytes and synthesis of pro-inflammatory cytokines. The pathophysiology of psoriasis is also associated with a decrease in anti-inflammatory functions of immunosuppressive cells. Recently, there are more cases of development of resistance to ongoing therapy with biologics in children, requiring cancellation of drug or its replacement. The aim of the study was to evaluate the content of T helper subpopulations in prognosis of effectiveness of biologics in children with psoriasis. Immunophenotyping of T helper populations was performed in 110 children with psoriasis vulgaris before appointment of biologics, at 16 and 52 weeks. Age of children ranged from 6 to 18 years. Severity of psoriasis and effectiveness of therapy were assessed by index PASI, which varied 0-68. Content of Tregs, Thact and Th17 was determined by flow cytometry. In group with a sufficient effect of biologics, a decrease in PASI was obtained, both at week 16 of therapy (p = 0.000) and by year of treatment, p = 0.017. In children with psoriasis, regardless of duration and effectiveness of biologics, percentage of Thact was increased relative to normal values. In group 1 before prescription of biologics was increased percentage of Thact (p = 0.005) and Th17 (p = 0.001). Analysis of dynamics of content of small populations of T helper during 1 year of use of biologics in children with different efficacy of therapy showed that significant changes were found in content of Th17 and Treg, as well as their Th17/Treg. ROC analysis showed that when Th17 deviation was above 53%, Thact above 181% and Th17/Treg above 2.6 before biologics were prescribed, insufficient efficacy of therapy could be expected in 75% of cases by year. By the end of induction course, with a Th17 deviation above 102% and a Th17/Treg above 2.6, probability of ineffective treatment was already 82%. The study shows the informative value of assessment of Thact before appointment of biologics, dynamics of Th17 by the end of induction course and Treg after 16 weeks of therapy in prognosis of effectiveness of biologics in children with psoriasis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>псориаз</kwd><kwd>биопрепараты</kwd><kwd>Т-хелперы</kwd><kwd>Th17</kwd><kwd>Treg</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>psoriasis</kwd><kwd>biologics</kwd><kwd>T helpers</kwd><kwd>Th17</kwd><kwd>Treg</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">Curmin R., Guillo S., de Rycke Y., Bachelez H., Beylot-Barry M., Beneton N., Chosidow O., Dupuy A., Joly P., Jullien D., Richard M.A., Viguier M., Sbidian E., Paul C., Mahe E., Tubach F.; PSOBIOTEQ Study GroupSwitches between biologics in patients with moderate-to-severe psoriasis: results from the French cohort PSOBIOTEQ.
