Цель работы заключалась в поиске ассоциаций эффективности терапии метотрексатом у больных ЮИА с различными сочетаниями полиморфных аллельных вариантов генов медиаторов иммунного ответа TNF-α rs1800629, IL10 rs1800872 и IL6 rs1800795. В статье представлен анализ распределения диплотипов IL10/IL6 и триплотипов TNF-α/IL10/IL6.  В исследовании приняли участие 239 пациентов, получавших базисную терапию с применением метотрексата. С целью генотипирования использовался метод real-time PCR. В подгруппе больных негативной формой ЮИА обнаружена ассоциация полиморфного варианта IL10 -592C&gt;A с отсутствием эффекта на терапию метотрексатом. Установлено, что при наличии одного аллеля IL10*A повышается вероятность отсутствия ответа на терапию, тогда как наличие генотипа *СС повышает шансы ответа. Идентифицированы диплотип (IL10*АA/IL6*GC) и триплотип (TNF-α*GG/IL10*AA/IL6*GC), достоверно чаще встречающиеся в общей группе больных с диагнозом ЮИА среди пациентов с отсутствием ответа на метотрексат. Предполагается, что полученные результаты при дальнейших исследованиях могут быть использованы в качестве фармакогенетических предикторов эффективности терапии у пациентов с ЮИА.</p></abstract><trans-abstract xml:lang="en"><p>Juvenile idiopathic arthritis (JIA) is ineffective in childhood and adolescence and responds to therapy largely due to genetic differences. The aim of the work was to search for associations of methotrexate therapy in JIA patients with the presence of polymorphic allelic variants of the immune response mediator genes TNF-α rs1800629, IL10 rs1800872 and IL6 rs1800795. The article presents an analysis of the distribution of IL10/IL6 diplotypes and TNF-α/IL10/IL6 triplotypes. The experiments involved 239 patients who received basic therapy with the use of methotrexate. For the purpose of genotyping, the real-time PCR method was used. In the subgroup of RF patients with anegative form of JIA, an association of the polymorphic variant IL10 -592C&gt;A with no effect on methotrexate therapy was found. Ithasbeen established that the presence of one IL10 *A allele increases the likelihood of a lack of response to therapy, while the presence of the *CC genotype increases the chances of a response. A diplotype (IL10*АA/IL6*GC) and a triplotype (TNF-α*GG/IL10*AA/IL6*GC) were identified, which are significantly more common in the general group of patients diagnosed with JIA among patients with no response to methotrexate. It is assumed that the results obtained in further studies can be used as pharmacogenetic predictors of the effectiveness of therapy in patients with JIA.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ювенильный идиопатический артрит</kwd><kwd>полиморфизм генов цитокинов</kwd><kwd>метотрексат</kwd><kwd>предиктивная медицина</kwd></kwd-group><kwd-group xml:lang="en"><kwd>juvenile idiopathic arthritis</kwd><kwd>cytokine gene polymorphism</kwd><kwd>methotrexate</kwd><kwd>predictive medicine</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках программы Приоритет 2030.</funding-statement><funding-statement xml:lang="en">The work was carried out as part of the Priority 2030 program.</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">Petty R.E., Southwood T.R., Manners .P, Baum J., Glass D.N, Goldenberg J. et al.
