Ювенильный артрит с системным началом — хроническое заболевание детского возраста, тяжесть которого обусловлена системными проявлениями, высоким риском развития таких осложнений, как синдром активации макрофагов и интерстициальное поражение легких, а также стойкого полиартрита с выраженными функциональными нарушениями. Терапия генно-инженерными биологическими препаратами существенно улучшила прогноз у этих пациентов, однако в реальной клинической практике остается немало вопросов о возможностях успешной коррекции терапии с целью поддержания длительной ремиссии.</p><p>Описание клинического случая. Представлено описание результатов длительного (9 лет) применения тоцилизумаба у пациентки с ранним дебютом ювенильного артрита с системным началом. Показано, что контроль над активностью заболевания может быть достигнут путем коррекции дозы препарата и интервалов между инфузиями.</p></sec><sec><title>Заключение</title><p>Заключение.

Systemic onset juvenile arthritis is a chronic disease of childhood. Its severity is determined by systemic manifestations, high risk of complications, such as macrophage activation syndrome, interstitial lung disease, and persistent polyarthritis with severe functional disorders. Genetically engineered biological drugs administration significantly improves the prognosis in these patients, thus, there are many questions about the possibilities of successful treatment correction in order to maintain long-term remission in real clinical practice.</p><p>Clinical case description. The results of long-term (9 years) administration of tocilizumab in female patient with early onset of systemic onset juvenile arthritis are presented. It has been shown that control over disease activity can be achieved via adjusting the drug dosage and the intervals between infusions.</p></sec><sec><title>Conclusion</title><p>Conclusion. Tocilizumab significantly improves prognosis of patients with systemic onset juvenile arthritis at good safety profile of this treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тоцилизумаб</kwd><kwd>ювенильный артрит с системным началом</kwd><kwd>дети</kwd><kwd>нейтропения</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tocilizumab</kwd><kwd>systemic onset juvenile arthritis</kwd><kwd>children</kwd><kwd>neutropenia</kwd><kwd>clinical case</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Подготовка рукописи выполнена в рамках финансирования фундаментальной научной темы № 1021051302580-4 в ФГБНУ НИИР им.
