Включено 125 больных РА с коморбидной депрессией, из них 102 (81,6%) женщины, средний возраст – 48,5±12,6 года; у большинства (86,4%) отмечалась высокая активность РА, а также неэффективность стабильной 12-недельной терапии синтетическими базисными противовоспалительными препаратами (сБПВП). У 34 (27,2%) пациентов была выявлена неэффективность одного или более генно-инженерных биологических препаратов. На неделе 0 все пациенты рандомизированы методом последовательных номеров в соотношении 2:2:1 в одну из трех групп: в группе 1 (n=49) проводилось лечение сБПВП + ОКЗ 64 мг подкожно 1 раз в 4 недели (к4н); в группе 2 (n=51) – лечение сБПВП + ОКЗ 64 мг подкожно к4н + психофармакотерапия (ПФТ); в группе 3 (n=25) – лечение сБПВП + ПФТ. Продолжительность исследования составила 24 недели. Концентрацию ИЛ-6 в сыворотке крови определяли с помощью мультиплексной технологии хMАР на анализаторе Bio-Plex Array System (Bio-Rad, США) и методом иммунохемилюминесценции (ИХЛ) на анализаторе Cobas e411 (Roche, Швейцария); уровень кальпротектина (КП) и рИЛ-6Р – методом иммуноферментного анализа (ИФА).</p></sec><sec><title>Результаты</title><p>Результаты. Применение ОКЗ сопровождалось статистически значимым снижением по группе в целом уровня С-реактивного белка (СРБ) и КП. Нормализация уровня СРБ отмечалась через 4 недели от начала терапии (р&lt;0,05). При сравнении групп пациентов, достигших (n=50) и не достигших ремиссии (n=50) по DAS28-СРБ (Disease Activity Score 28 с определением уровня CРБ) к 24-й неделе терапии ОКЗ, отмечены статистически значимые различия по концентрации КП, медиана которой составила 1,54 [1,2; 2,56] и 2,42 [1,5; 4,54] мкг/мл соответственно (р=0,022). В то же время уровень СРБ в этих группах существенно не различался: 0,45 [0,2; 0,7] и 0,6 [0,2; 0,9] мг/мл соответственно. Наблюдалось статистически значимое снижение концентрации ИЛ-6 по группе в целом в 5,5 раза после 12 недель и в 3,5 раза после 24 недель терапии. Уровень рИЛ-6Р снижался по группе в целом и среди пациентов с хорошим ответом на терапию (p&lt;0,05).</p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, на фоне лечения ОКЗ наблюдается снижение уровня острофазовых показателей, КП, ИЛ-6 (при использовании метода ИХЛ) и рИЛ-6Р. КП можно считать более чувствительным маркером для оценки воспаления на фоне терапии ОКЗ по сравнению с СРБ.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim – to evaluate the effect of olokizumab (OKZ) on acute-phase reactants, interleukin (IL) 6, and its soluble receptor (sIL-6R) levels in patients with rheumatoid arthritis (RA) and comorbid depression.</p><sec><title>Material and methods</title><p>Material and methods. A total of 125 patients with RA and comorbid depression were included, including 102 (81.6%) women, with a mean age of 48.5±12.6 years. The majority (86.4%) had high RA activity and had failed stable 12-week therapy with synthetic disease-modifying antirheumatic drugs (DMARDs). Thirty-four (27.2%) patients had failed one or more biological agents. At week 0, all patients were randomized using the sequential numbers method in a 2:2:1 ratio to one of three groups: Group 1 received treatment with sDMARDs + OKZ 64 mg subcutaneously once every 4 weeks (n=49); group 2 – sDMARDs + OKZ 64 mg subcutaneously + psychopharmacotherapy (PPT) (n=51); group 3 – sDMARDs + PFT (n=25). The study duration was 24 weeks. Serum IL-6 concentrations were determined using xMAP multiplex technology on a Bio-Plex Array System analyzer (Bio-Rad, USA) and immunochemiluminescence assay (ICL) on a Cobas e411 analyzer (Roche, Switzerland).</p></sec><sec><title>Results</title><p>Results. The use of OKZ was accompanied by a significant decrease in the level of C-reactive protein (CRP) and calprotectin (CP) in the group as a whole; normalization of the CRP level was noted 4 weeks after the start of therapy (p&lt;0.05). When comparing the groups of patients who achieved (n=50) and did not achieve remission (n=50) according to the EULAR (European Alliance of Associations for Rheumatology) criteria (according to DAS28-CRP (Disease Activity Score 28 with CRP determination)) by 24 weeks of OKZ therapy, significant differences were noted in the concentration of CP (respectively, 1.54 [1.2; 2.56] versus 2.42 [1.5; 4.54] μg/ml; p=0.022) in contrast to CRP (0.45 [0.2; 0.7] versus 0.6 [0.2; 0.9] mg/ml). There was a significant decrease in the concentration of IL-6 in the group as a whole by 5.5 times after 12 weeks and by 3.5 times after 24 weeks of therapy. The level of sIL-6R decreased in the group as a whole and among patients with a good response to therapy (p&lt;0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. Thus, the use of OKZ is accompanied by a decrease in the levels of acute-phase reactants, CP, IL-6, and sIL-6R. CP can be considered a more sensitive marker for assessing inflammation during OKZ therapy compared to CRP.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>олокизумаб</kwd><kwd>ревматоидный артрит</kwd><kwd>кальпротектин</kwd><kwd>интерлейкин 6</kwd><kwd>растворимые рецепторы ИЛ-6</kwd></kwd-group><kwd-group xml:lang="en"><kwd>olokizumab</kwd><kwd>rheumatoid arthritis</kwd><kwd>calprotectin</kwd><kwd>interleukin 6</kwd><kwd>soluble IL-6 receptors</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проводилось в рамках фундаментального научного исследования ФГБНУ НИИР им.
