В наблюдательное ретроспективное исследование было включено 72 пациента (29 мальчиков и 43 девочки) с диагнозом сЮИА, верифицированным согласно критериям ILAR, получавших ТЦЗ ≥12 мес, у которых предшествующая терапия различными противоревматическими препаратами оказалась неэффективной. Изучалась динамика основных клинических и лабораторных показателей активности сЮИА на фоне коррекции интервала между инфузиями.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. В исследованной группе медиана возраста дебюта составила 3,8 [2,1; 5,9] года, продолжительности заболевания перед назначением ТЦЗ – 26,5 [9,25; 62,25] мес. Терапию продолжают 70 пациентов, медиана продолжительности терапии 5,0 [2,75; 6,38] года. Исходный интервал между инфузиями ТЦЗ составил 2 нед у 49 (1-я группа) и 4 нед – у 23 пациентов (2-я группа). После 6 мес терапии во 2-й группе интервал сокращен до 2 нед у 15 (65,2%) пациентов в связи со снижением эффективности. При пролонгировании сроков между введениями ТЦЗ у пациентов 1-й группы, не достигших неактивного статуса болезни на 1-м году заболевания, выявлено достоверное повышение СОЭ, уровня С-реактивного белка и обострение системных проявлений сЮИА (р&lt;0,01) при отсутствии статистически значимой динамики показателей суставного статуса (p&gt;0,05). У 40% этих пациентов отмечено вовлечение «новых» суставов, в том числе тазобедренных. «Предвестниками» обострения в период увеличения интервалов между инфузиями являлись: артралгии (88%), миалгии (65%), боли в горле (30%), дисфория (50%, чаще у детей дошкольного возраста), нарастание уровня ферритина и числа лейкоцитов. У 90,3% больных, достигших неактивного статуса болезни, удалось постепенно увеличить интервал между инфузиями. У 6 пациентов ТЦЗ отменен путем постепенного увеличения интервалов, у 4 из них терапия возобновлена с исходным интервалом 2 нед через 3, 6, 21 и 22 мес соответственно, у двух пациенток сохраняется безмедикаментозная ремиссия 23 и 20 мес. Сокращение интервалов до исходных 2 нед выполнено у 13 (18,1%) пациентов. Развитие обострений с необходимостью сокращения интервала до исходного чаще всего наблюдалось на 24–35-м месяце терапии, что хронологически совпало с периодом активного роста. В настоящее время 15 пациентов получают ТЦЗ с интервалом 5–6 нед, 40 – с интервалом 4 нед, 9 больных – 3 нед, у 6 пациентов попытка увеличения интервала свыше 2–2,5 нед оказалась неудачной.</p></sec><sec><title>Заключение</title><p>Заключение. Накопленный опыт свидетельствует о необходимости соблюдения двухнедельного интервала между инфузиями ТЦЗ на начальном этапе терапии у большинства больных сЮИА до достижения неактивной стадии болезни с последующим индивидуальным плавным увеличением интервала до 4 нед (по 2–3 дня под тщательным врачебным контролем), при появлении начальных признаков обострения необходимо сокращение интервала до 2 нед. До решения вопроса о полной отмене ТЦЗ целесообразно увеличить интервал между инфузиями до 5–6 нед под тщательным клинико-лабораторным контролем.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to assess the possibility of using varying interval between intravenous infusions of tocilizumab (TCZ) as a tool for choosing the optimal treatment regimen in systemic juvenile arthritis (SJA).</p></sec><sec><title>Subjects and methods</title><p>Subjects and methods. The observational retrospective study included 72 patients (29 boys and 43 girls) with a SJA fulfilled ILAR criteria, who received TCZ ≥12 months, in which previous therapy with various anti-rheumatic drugs was ineffective. We studied the changes of the main clinical and laboratory parameters of the SJA activity after correction of the interval between infusions.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. In the studied group median age of onset was 3.8 [2.1; 5.9] years, duration of disease before the appointment of TCZ – 26.5 [9.25; 62.25] months. Therapy is continued by 70 patients, the median duration of therapy is 5.0 [2.75; 6.38] years. The initial interval between TCZ infusions was 2 weeks in 49 (group 1) and 4 weeks in 23 patients (group 2). After 6 months of therapy in group 2, the interval was reduced to 2 weeks in 15 (65.2%) patients due to decreased effectiveness. Prolongation of the period between the introduction of TCZ in patients of group 1 who did not reach the inactive status of the disease in the 1st year of the disease resulted in a significant increase of erythrocyte sedimentation rate, C-reactive protein level and exacerbation of systemic manifestations of SJA (p&lt;0.01) in the absence of statistically significant changes of joint status parameters (p&gt;0.05). 40% of these patients had involvement of «new» joints, including hip joints. «Harbingers» of exacerbation in the period of increasing intervals between infusions were: arthralgia (88%), myalgia (65%), sore throat (30%), dysphoria (50%, more often in preschool children), increase of ferritin level and number of leukocytes. In 90.3% of patients who have reached the inactive status of the disease, it was possible to gradually increase the interval between infusions. In 6 patients, TCZ was canceled by gradually increasing the intervals, in 4 of them, therapy was resumed at an initial interval of 2 weeks after 3, 6, 21 and 22 months, respectively, in two patients, a drug-free remission was maintained during 23 and 20 months. Reduction of intervals to the initial 2 weeks was performed in 13 (18.1%) patients. The development of exacerbations with the need to reduce the interval to the initial one was most often observed at 24–35 months of therapy, which chronologically coincided with the period of active growth. Currently, 15 patients receiving TCZ with an interval of 5–6 weeks, and 40 – with an interval of 4 weeks, 9 patients – 3 weeks, in 6 patients attempt to increase the interval to more than 2–2,5 weeks was unsuccessful.</p></sec><sec><title>Conclusion</title><p>Conclusion. Experience suggests the need to comply with a two-week interval between infusions of TCZ at the initial stage of therapy in most patients with SJA until the inactive stage of the disease, followed by a smooth individual increase in the interval to 4 weeks (2–3 days under careful medical supervision). Appearance of initial signs of exacerbation, requires to reduce the interval to 2 weeks. Before deciding on the complete withdrawal of TCZ, it is advisable to increase the interval between infusions to 5–6 weeks under careful clinical and laboratory control.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>системный ювенильный идиопатический артрит</kwd><kwd>тоцилизумаб</kwd><kwd>ремиссия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>systemic juvenile idiopathic arthritis</kwd><kwd>tocilizumab</kwd><kwd>remission</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">De Benedetti F, Massa M, Pignatti P, et al.
