В исследование включено 167 пациентов с РА. В 1-ю группу вошли пациенты с ВД РА ≤45 лет (медиана ВД – 36 [29; 42] лет; n=95), во 2-ю группу – пациенты с ВД РА ≥60 лет (медиана ВД – 66,5 [62; 70] лет; n=72). Контролем служила ДНК 301 здорового донора. Всем пациентам проводилось генотипирование полиморфизмов гена IL-6 методом полимеразной цепной реакции.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. У пациентов с ВД ≥60 лет генотип СС выявлялся чаще, чем у пациентов с ВД ≤45 лет (соответственно в 31,9 и 12,6% случаев; p=0,01). У больных РА с генотипом CC риск развития заболевания в возрасте ≥60 лет был почти в 3 раза выше по сравнению с носителями других генотипов (отношение шансов 3,25; 95% доверительный интервал 1,39–7,65; p=0,004).</p></sec><sec><title>Заключение</title><p>Заключение. Установленная ассоциация генотипа СС полиморфизма -174 G/C гена IL-6 с развитием РА после 60 лет позволяет рассматривать данный генетический вариант в качестве предиктора возникновения РА в пожилом возрасте, что подтверждает обоснованность стратификации РА по возрастным фенотипам и открывает перспективы для разработки диагностических и превентивных подходов.</p></sec></abstract><trans-abstract xml:lang="en"><p>Genetic polymorphism of the IL-6 gene (-174 G/C, rs1800795) may affect interleukin-6 expression and contribute to the development of age-associated phenotypes of rheumatoid arthritis (RA).</p><sec><title>Objective</title><p>Objective: to study the distribution of IL-6 gene alleles and genotypes in RA patients depending on age at onset (AAO).</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 167 patients with RA. Group 1 included patients with RA AAO ≤45 years (median AAO 36 [29; 42] years; n=95); Group 2 included patients with RA AAO ≥60 years (median AAO 66.5 [62; 70] years; n=72). DNA from 301 healthy donors served as controls. All patients underwent genotyping of IL-6 gene polymorphisms using polymerase chain reaction.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. In patients with AAO ≥60 years, the CC genotype was detected more often than in patients with AAO ≤45 years (31.9% vs 12.6%, respectively; p=0.01). In RA patients with the CC genotype, the risk of developing the disease at the age of ≥60 years was almost three times higher compared with carriers of other genotypes (odds ratio 3.25; 95% confidence interval 1.39–7.65; p=0.004).</p></sec><sec><title>Conclusion</title><p>Conclusion. The established association of the CC genotype of the -174 G/C polymorphism of the IL-6 gene with the development of RA after 60 years allows this genetic variant to be considered a predictor of RA onset in older age, which supports the rationale for stratifying RA by agerelated phenotypes and opens prospects for the development of diagnostic and preventive approaches.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>пожилой возраст</kwd><kwd>интерлейкин-6</kwd><kwd>полиморфизм гена</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>older age</kwd><kwd>interleukin-6</kwd><kwd>gene polymorphism</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках фундаментальной научной темы FURS-2022-008 (государственное задание №1021051503137-7).</funding-statement><funding-statement xml:lang="en">The article was prepared within the framework of the fundamental research project FURS-2022-008 (state assignment №1021051503137-7).</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">Насонов ЕЛ, редактор.
