Биологическая терапия позволяет уменьшить токсичность кортикостероидов и надежно контролировать течение заболевания.Цель исследования. Оценка эффективности и безопасности терапии ритуксимабом у детей с системной красной волчанкой. Материалы и методы. В ретроспективное исследование включены данные о 48 пациентах с системной красной волчанкой, получавших терапию ритуксимабом. Диагноз системной красной волчанки был установлен на основании классификационных критериев SLICC. У пациентов оценивали статус болезни исходно, на момент назначения ритуксимаба и затем ежегодно. Ритуксимаб назначали в связи с наличием волчаночного нефрита, поражения ЦНС, системы крови, неконтролируемых стандартной терапией, а также в случае выраженной кортикостероидной токсичности.Результаты. На фоне терапии ритуксимабом отмечено значительное снижение индекса активности SELENA–SLEDAI. Выявлены существенное снижение уровня антител к двуспиральной ДНК, нормализация уровня гемоглобина, СОЭ, комплемента С4. Уменьшилась доля пациентов с цитопениями; их полное отсутствие отмечено у пациентов, получающих терапию в течение 3 лет. Число пациентов с активным волчаночным нефритом уменьшилось с 16 на момент начала применения ритуксимаба до 1 через 3 года терапии. Отмечена существенная динамика протеинурии и гематурии, за исключением таковой у 1 пациента. Суточная доза кортикостероидов была снижена на 90% от исходной у пациентов, получавших терапию в течение 3 лет. Среди клинически значимых нежелательных явлений были 3 летальных исхода у пациентов с высокоактивным течением системной красной волчанки с неконтролируемым синдромом активации макрофагов, ассоциированным с инфекциями. Кроме того, фиксировались различные инфекционные осложнения, гипогаммаглобулинемия, требовавшие заместительной терапии внутривенным иммуноглобулином.Заключение. Ритуксимаб может рассматриваться как вариант терапии для лечения тяжелых форм системной красной волчанки, резистентных к стандартной терапии. Требуются дальнейшие исследования для оценки эффективности и безопасности.</p></abstract><trans-abstract xml:lang="en"><p>Systemic lupus erythematosus is an immunopathological disease which is characterized by a poor prognosis. Biologics applied in the disease treatment allow reducing the corticosteroid toxicity and controlling the disease.Purpose. To evaluate the efficacy and safety of rituximab therapy in children with systemic lupus erythematosus.Material and methods. The retrospective study included data of 48 patients with systemic lupus erythematosus treated with rituximab. Systemic lupus erythematosus was diagnosed based on the SLICC classification criteria. Patients were assessed at baseline disease status, at the time of rituximab initiation and follow-up. The indications for the rituximab were: lupus nephritis, CNS involvement, and hematological involvement resistant to the standard therapy, and in cases of severe corticosteroid toxicity.Results. During rituximab therapy the significant decrease of the SELENA–SLEDAI activity index was observed. There was a significant decrease of the level of antibodies against dsDNA, normalization of the levels of hemoglobin, ESR, complement C4. The proportion of patients with cytopenia decreased up to their complete absence in patients receiving therapy for three years. The number of patients with active lupus nephritis decreased from 16 at the time of rituximab initiation to 1 after 3 years of therapy. Significant dynamics of proteinuria and hematuria was noted, except for 1 patient. The daily dose of corticosteroids was reduced by 90% from baseline in patients treated for 3 years. Serious adverse events included three deaths in patients with high systemic lupus erythematosus activity with uncontrolled macrophage activation syndrome associated with infections. Various infectious complications, hypogammaglobulinemia, which required replacement therapy with intravenous immunoglobulin, were also recorded.Conclusion. Rituximab can be considered as an option for the treatment of severe forms of systemic lupus erythematosus which are resistant to standard therapy. Further studies are required to evaluate efficacy and safety.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>системная красная волчанка</kwd><kwd>В-клетки</kwd><kwd>ритуксимаб</kwd><kwd>волчаночный нефрит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>systemic lupus erythematosus</kwd><kwd>B-cells</kwd><kwd>rituximab</kwd><kwd>lupus nephritis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Минобрнауки РФ (соглашение № 075–15–2022–301).</funding-statement><funding-statement xml:lang="en">The study was financially supported by the Ministry of Science and Higher Education of the Russian Federation (Agreement No. 075–15–2022–301).</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">Watson L., Beresford M.W., Maynes C., Pilkington C., Marks S.D., Glackin Yu. et al.
