Внедрение в клиническую практику генно-инженерных биологических препаратов, включая гуманизированные моноклональные антитела (IgG1) к рецепторам интерлейкина-6 (IL-6R), обусловливает необходимость поиска предикторов эффективного ответа на проводимую терапию.</p><p>Целью исследования стало определение роли мультиплексного анализа цитокинов в оценке эффективности применения тоцилизумаба (ТЦЗ) при РА.</p><sec><title>Материал и методы</title><p>Материал и методы. Обследовано 43 пациента с РА. Группу сравнения составили 297 здоровых доноров, сопоставимых по полу и возрасту с обследованными больными. Концентрацию IgM и IgA ревматоидных факторов (РФ) и С-реактивного белка (СРБ) в сыворотке крови измеряли иммунонефелометрическим методом; антител к циклическому цитруллинированному пептиду (АЦЦП), модифицированному ци-труллинированному виментину (АМЦВ), матрикснойметаллопротиназы-3 (ММП-3) -методом иммуноферментного анализа; цитокинов - методом мультиплексного анализа по технологии xMAP.</p></sec><sec><title>Результаты</title><p>Результаты. На 4-й неделе терапии ТЦЗ у пациентов с РА наблюдалось снижение СРБ, IgM РФ, АМЦВ, ММП-3; на 8-й - СОЭ, СРБ, IgM и IgA РФ, антител к цитруллинированным белкам, на 24-й - всех исследуемых биомаркеров, исключая АЦЦП. На4-й, 8-й24-йнеделях терапии отмечено снижение сывороточных уровней всех исследуемых цитокинов (исключая П.-6-4-я неделя, IL- 1ra на 8-й и 24-й неделях). Наиболее сильными факторами для прогнозирования эффективности ТЦЗ являются ММП-3 (ППК = 0,7), АЦЦП (0,7) и VEGF (0,7). Прогностическая модель, основанная на оценке уровней данных биомаркеров до начала терапии, позволяет с высокой диагностической точностью прогнозировать клинический ответ на ТЦЗ при РА (ППК = 0,85; ДИ: 0,7-1,0).</p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, данные о связи базальных сывороточных концентраций АЦЦП, ММП-3 и VEGF с наличием хорошего ответа у пациентов с РА дали возможность создать многопараметрический диагностический индекс, позволяющий повысить точность прогнозирования эффективности ТЗЦ.</p></sec></abstract><trans-abstract xml:lang="en"><p>Rheumatoid arthritis (RA) is an autoimmune rheumatic disease of unknown etiology, characterized by chronic erosive arthritis (synovitis) and that can involve other tissues and organs. The use of biologics in clinical practice, including humanized monoclonal antibodies (IgG1) to interieukin-6 (IL-6R) receptors, it's the cause to search for predictors of response to this therapy.</p><p>The aim of this study was to determine the relevance of multiplex cytokine analysis in evaluating the effectiveness of tocilizumab (TCZ) in RA.</p><sec><title>Materials and methods</title><p>Materials and methods. We examined serum samples from 43 patients with RA. The comparison group was 297 healthy subjects matched by gender and age. Serum concentration of IgM and IgA rheumatoid factors (RF) and C-reactive protein (CRP) in serum was measured by immunonephelometry; of antibodies to cyclic citrullinated peptide (anti-CCP), antibodies to modified citrullinatedvimentin (anti-MCV), matrix metalloprotinase-3 (MMP-3) - by enzyme-linked immunosorbent assay; of cytokines - by xMAP technology.</p></sec><sec><title>Results</title><p>Results. At week 4 on TCZ therapy, patients with RA had a decrease serum levels of CRP, IgM RF, AMCV, MMP-3; on 8th - ESR, CRP, IgM and IgA RF, anti-CCP and anti-MCV, on the 24th - of all biomarkers, excluding anti-CCP. At 4th, 8th, 24th weeks of therapy, there was a decrease in serum levels of all studied cytokines (excluding IL-6 at 4th week and IL- 1ra at 8th and 24th weeks). The most associated factors witch effectiveness of TCZ are: MMP-3 (AUC0.7), anti-CCP (0.7) and VEGF (0.7). A predictive model based on the assessment of serum levels of this biomarkers can predicting the clinical response to TCZ in RA (AUC = 0.85; CI: 0.7-1.0).</p></sec><sec><title>Conclusion</title><p>Conclusion. The data about association of basal serum concentrations of anti-CCP, MMP-3 and VEGF with the response in RA patients, made it possible to create a multiparameter index for predicting the TCZ effectiveness.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>тоцилизумаб</kwd><kwd>мультиплексный анализ биомаркеров</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>tocilizumab</kwd><kwd>multiplex biomarker assay</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда, проект № 19-15-00283 «Поиск сигнатур белковых биомаркеров для ранней диагностики, оценки активности и выбора тактики терапии системных аутоиммунных ревматических заболеваний»</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">Harris E.
