Наиболее благоприятные условия для изменения течения болезни складываются в первые месяцы после ее начала. Метотрексат (МТ) занимает ведущее место в терапии РА. Назрела необходимость в разработке инструментов, которые позволят предсказывать эффективность и переносимость МТ на самых ранних этапах лечения РА. Концентрация активных метаболитов МТ рассматривается как потенциальный биомаркер, с помощью которого возможно предсказать, каким будет ответ на терапию этим препаратом.</p><p>В статье приводится анализ наиболее актуальных работ, посвященных изучению концентрации активных метаболитов МТ – полиглутаматов (МТПГ) у больных РА. Показано, что представленные исследования не охватывают все возможности терапевтического лекарственного мониторинга, в частности определение содержания МТПГ в мононуклеарах в динамике. Необходимы дальнейшие исследования с целью разработки объективного подхода к назначению МТ у больных РА.</p></abstract><trans-abstract xml:lang="en"><p>Rheumatoid arthritis (RA) is characterized by a progressive course with the formation of joint deformities and the development of severe functional disorders. The most favorable conditions for changing the course of the disease emerge in the first months after its onset. Methotrexate (MTX) occupies a leading position in the treatment of RA. There is a need to develop tools that will be able to predict the efficacy and tolerability of MTX at the earliest stages of RA treatment. The concentration of active metabolites of MTX is considered as a potential biomarker that enables one to predict what response to therapy with this drug will be.</p><p>The paper analyzes the most relevant works devoted to the study of the concentration of active MTX metabolites polyglutamates (MTX PGs) in patients with RA. It is shown that the presented studies do not cover all the possibilities of therapeutic drug monitoring, in particular the determination of the levels of MTX PGs in mononuclear cells over time. Further investigation is needed to develop an objective approach to prescribing MTX in RA patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>метотрексат</kwd><kwd>полиглутамат</kwd><kwd>мониторинг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>methotrexate</kwd><kwd>polyglutamate</kwd><kwd>drug monitoring</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Олюнин ЮА.
