Обследовано 20 больных с достоверным диагнозом РА. Всем пациентам проведено по 2 инфузии РТМ (Ацеллбия®) в дозе 600 мг внутривенно с интервалом в 2 нед на фоне терапии метотрексатом, нестероидными противовоспалительными препаратами и глюкокортикоидами. Клинические и лабораторные показатели анализировались непосредственно перед началом терапии, а затем через 12 и 24 нед после первой инфузии препарата.Результаты и обсуждение. К 24-й неделе терапии РТМ хороший/умеренный эффект по критериям EULAR зарегистрирован у 17 (85%) пациентов; ремиссия по DAS28 (&lt;2,6) достигнута у 4 (20%) больных, SDAI ( ≤3,3) – у 2 (10%), CDAI ( ≤2,8) – у 1 (5%). До начала лечения активный синовит по данным энергетического допплеровского картирования (ЭД) выявлен у 13 (65%) пациентов, а при сканировании в режиме серой шкалы – у 20 (100%). На фоне терапии биоаналогом РТМ наблюдалось значимое уменьшение воспалительных изменений в суставах, и к 24-й неделе после начала лечения медиана ЭД составила 0,5; активное воспаление сохранялось у 7 (35%) больных. Как показал ROC-анализ, исходный уровень интерлейкина (ИЛ) 6 &gt;100,0 пг/мл ассоциируется с сохранением воспалительной активности по данным ЭД к 24-й неделе терапии биоаналогом РТМ, при этом чувствительность составила 85% и специфичность – 62% (AUC 0,78, 95% доверительный интервал 0,57–0,99)Заключение. Выявлена ассоциация между повышенным уровнем провоспалительных цитокинов, в основном ИЛ6, и активностью синовиального воспаления по данным УЗИ. Для прогнозирования сохраняющейся воспалительной активности по результатам ЭД наиболее перспективным маркером является ИЛ6, другие анализируемые показатели имеют худшие параметры чувствительности и специфичности.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to assess the relationship between laboratory biomarkers and ultrasonographic signs of inflammation in patients with rheumatoid arthritis during therapy with a rituximab (RTM) biosimilar.Patients and methods. 20 patients with definite diagnosis of RA were examined. All patients received 2 infusions of RTM (Acellbia®), at a dose of 600 mg intravenously 2 weeks apart during therapy with methotrexate, non-steroidal anti-inflammatory drugs and glucocorticoids. Clinical and laboratory parameters were analyzed immediately before the start of therapy, and then 12 and 24 weeks after the first infusion of the drug.Results and discussion. By the 24th week of RTM therapy, a good/moderate effect according to the EULAR criteria was registered in 17 (85%) patients; remission according to DAS28 (&lt;2.6) was achieved in 4 (20%) patients, SDAI (≤3.3) – in 2 (10%), CDAI (≤2.8) – in 1 (5%). Prior to the start of treatment, active synovitis was detected in 13 (65%) patients by power Doppler imaging (PD), and in 20 (100%) patients by gray scale scanning. During therapy with the RTM biosimilar, a significant decrease in inflammatory changes in the joints was observed, and by the 24th week after the start of treatment, the median PD was 0.5; active inflammation persisted in 7 (35%) patients. As shown by ROC analysis, the initial level of interleukin (IL) 6 &gt;100.0 pg/ml is associated with the persistence of inflammatory activity according to PD by the 24th week of therapy with the RTM biosimilar, while the sensitivity was 85% and the specificity was 62% (AUC 0.78, 95% CI 0.57–0.99)Conclusion. An association was found between an increased level of pro-inflammatory cytokines, mainly IL6, and the activity of synovial inflammation according to ultrasound data. IL6 is the most promising marker for predicting persistent inflammatory activity based on the results of PD; other analyzed parameters have worse sensitivity and specificity parameters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>активность заболевания</kwd><kwd>ультразвуковое исследование</kwd><kwd>провоспалительные цитокины</kwd><kwd>биоаналог ритуксимаба</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>disease activity</kwd><kwd>sonography</kwd><kwd>pro-inflammatory cytokines</kwd><kwd>rituximab biosimilar</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания по теме AAAA-A20-120040190015-5.</funding-statement><funding-statement xml:lang="en">The investigation has been conducted as part of the government program, scientific topic №AAAA-A20-120040190015-5.</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">Wain DL.
