Результаты его применения продемонстрированы в многоцентровых и национальных исследованиях.</p><p>Цель исследования — оценить эффективность и безопасность применения этанерцепта у детей с несистемными вариантами ЮИА, определить предикторы достижения ремиссии и факторы риска развития обострений.</p><sec><title>Методы</title><p>Методы. В ретроспективном когортном исследовании проанализированы результаты лечения (ремиссия, обострения, нежелательные явления) этанерцептом у детей с несистемными формами ЮИА. Минимальный период отслеживания исходов исследования — 6 мес.</p></sec><sec><title>Результаты</title><p>Результаты. Период ремиссии в течение 6–36 мес наступил у 77/131 (58,8%), обострения развились у 18/129 (14,0%) больных. Предикторами достижения ремиссии были возраст дебюта ЮИА &lt; 8 лет [относительный риск (ОР) 2,05; 95% доверительный интервал (ДИ) 1,27–3,23], возраст назначения этанерцепта ≤ 10 лет (ОР 1,7; 95% ДИ 1,22–2,38), время болезни до назначения этанерцепта &lt; 2,5 лет (ОР 2,4; 95% ДИ 1,4–4,4), наличие антигена HLA-B27 (ОР 2,15; 95% ДИ 0,98–4,75; р = 0,06). Риск обострений был выше у детей с полиартикулярным вариантом ЮИА (ОР 2,7; 95% ДИ 0,9–8,2; р = 0,08), тогда как использование метотрексата в терапии снижало риск обострений (ОР 0,32; 95% ДИ 0,1–1,15; р = 0,05). Этанерцепт по причине первичной (улучшение по критериям АКРпеди через 3 мес терапии &lt; 30%) или вторичной (потеря ранее достигнутого ≥ 30% улучшения) неэффективности был отменен у 14/152 (9,2%) больных, увеит de novo развился у 8/152 (5,3%) пациентов, реакции в месте инъекции — у 6/152 (4,0%).</p></sec><sec><title>Заключение</title><p>Заключение. Терапия, включающая этанерцепт, с большей вероятностью индуцирует ремиссию у пациентов младшего возраста при дебюте ЮИА в возрасте до 8 лет и длительности анамнеза менее 2,5 лет. Высокий риск обострений отмечен у пациентов с полиартикулярным ЮИА, низкий — у получавших в составе комбинированной терапии метотрексат.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Etanercept is a biological drug most commonly used in patients with juvenile idiopathic arthritis (JIA). The results of its use are showed in local studies.</p></sec><sec><title>Objective</title><p>Objective. Our aim was to evaluate the efficacy and safety of the use of etanercept in children with non-systemic JIA, to determine the predictors of remission and the risk factors for the development of exacerbations.</p></sec><sec><title>Methods</title><p>Methods. In a retrospective cohort study, the results of etanercept treatment (remission, exacerbations, adverse events) in children with non-systemic JIA were analyzed. The minimum follow-up period was 6 months.</p></sec><sec><title>Results</title><p>Results. The period of remission within 6–36 months occurred in 77/131 (58.8%), exacerbations developed in 18/129 (14.0%) patients. Predictors of achieving remission were the age of JIA onset &lt; 8 years [relative risk (RR) 2.05; 95% confidence interval (CI) 1.27–3.23], the age of prescribing etanercept ≤ 10 years (RR 1.7, 95% CI 1.22–2.38), the time of the disease prior to etanercept prescription &lt; 2.5 years (RR 2.4, 95% CI 1.4–4.4), the presence of HLA-B27 antigen (RR 2.15, 95% CI 0.98–4.75; p = 0.06). The risk of exacerbations was higher in children with polyarticular JIA (RR 2.7, 95% CI 0.9–8.2; p = 0.08), whereas methotrexate therapy reduced the risk of exacerbations (RR 0.32, 95% CI 0.1–1.15; p = 0.05). Etanercept was discontinued due to primary (improvement by the ACRpedi criteria after 3 months of therapy &lt;30%) or secondary (loss of previously achieved ≥ 30% improvement) failure in 14/152 (9.2%) patients; de novo uveitis developed in 8/152 (5.3%) patients; reactions at the injection site — in 6/152 (4.0%) patients.</p></sec><sec><title>Conclusion</title><p>Conclusion. Therapy involving etanercept is more likely to induce remission in younger patients with JIA onset at the age of 8 years and a history of less than 2.5 years. A high risk of exacerbations was noted in patients with polyarticular JIA, and low one — in those receiving methotrexate as a part of combined therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>ювенильный идиопатический артрит</kwd><kwd>этанерцепт</kwd><kwd>ремиссия</kwd><kwd>обострения</kwd><kwd>факторы риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>juvenile idiopathic arthritis</kwd><kwd>etanercept</kwd><kwd>remission</kwd><kwd>exacerbations</kwd><kwd>risk factors</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Пфайзер, компания</funding-statement><funding-statement xml:lang="en">Pfizer, support</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ravelli A, Martini A.
