У 200 женщин с РА (медиана возраста – 60,0 [52,5; 65,5] лет) проводилось определение АММ с помощью двухэнергетической рентгеновской абсорбциометрии для выявления наличия саркопенического фенотипа (СПФ); также выполнено определение уровня С-реактивного белка (СРБ), ревматоидного фактора, антител к циклическому цитруллинированному пептиду. У 87 пациенток исследовали уровни сывороточного миостатина, фоллистатина, интерлейкина 6 (ИЛ-6), рецепторов к ИЛ-6, инсулиноподобного фактора роста 1 (ИФР-1), адипонектина, лептина, фактора роста фибробластов 23 (ФРФ23), фактора некроза опухоли SF12 (superfamily member 12).Результаты. Пациентки, имевшие и не имевшие СПФ, различались по уровню СРБ (медиана – 8,6 [1,3; 22,2] и 5,6 [1,2; 17,4] мг/л соответственно; р=0,041) и лептина (медиана – 3,8 [2,4; 5,7] и 5,4 [3,8; 6,9] нг/мл соответственно; р=0,030). АММ коррелировала с уровнем СРБ, фоллистатина и лептина. В линейном многофакторном регрессионном анализе выявлена взаимосвязь между мышечной массой и фоллистатином (β=–0,35; р=0,007), ИФР-1 (β=–0,38; р=0,002), лептином (β=0,36; р=0,004) и ФРФ23 (β=0,33; р=0,008).Заключение. Проведенное исследование показало, что у больных РА состояние мышечной массы связано с уровнем фоллистатина, ИФР-1, лептина и ФРФ23.</p></abstract><trans-abstract xml:lang="en"><p>Aim – to evaluate the association among appendicular lean mass and immunological markers of blood serum in women with rheumatoid arthritis (RA).Material and methods. 200 women with RA (median age – 60.0 [52.5; 65.5] years) were enrolled in the study. Using dual-energy X-ray absorptiometry appendicular lean mass (ALM) was measured to determine the sarcopenic phenotype of body composition. The assessment of C-reactive protein (CRP), rheumatoid factor, and antibodies to cyclic citrullinated peptide was also performed. The levels of serum myostatin, follistatin, interleukin 6 (IL-6), IL-6 receptors, insulin-like growth factor 1 (IGF-1), adiponectin, leptin, fibroblast growth factor 23 (FGF23), tumor necrosis factor SF12 (superfamily member 12) were studied in 87 patients.Results. According to the presence of the sarcopenic phenotype the patients differed in the levels of CRP (8.6 [1.3; 22.2] and 5.6 [1.2; 17.4] mg/l, respectively; p=0.041) and leptin (3.8 [2.4; 5.7] and 5.4 [3.8; 6.9] ng/ml, respectively; p=0.030). ALM correlated with the levels of CRP, follistatin and leptin. Linear multivariate regression analysis revealed the association between ALM index and follistatin (β=–0.35; p=0.007), IGF1 (β=–0.38; p=0.002), leptin (β=0.36; p=0.004) and FGF23 (β=0.33; p=0.008).Conclusion. The study showed that there is an association between the lean mass and the level of follistatin, IGF-1, leptin and FGF23 in patients with RA.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>саркопения</kwd><kwd>цитокины</kwd><kwd>адипокины</kwd><kwd>миокины</kwd><kwd>фоллистатин</kwd><kwd>лептин</kwd><kwd>фактор роста фибробластов 23</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>sarcopenia</kwd><kwd>cytokines</kwd><kwd>adipokines</kwd><kwd>myokines</kwd><kwd>follistatin</kwd><kwd>leptin</kwd><kwd>fibroblast growth factor 23</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках фундаментальной научной темы «Разработка междисциплинарной персонализированной модели оказания помощи пациентам с аутовоспалительными дегенеративными заболеваниями (остеоартрит, остеопороз, саркопения, подагра, пирофосфатная артропатия) и мультиморбидностью (ожирение, сердечно-сосудистые заболевания)» , регистрационный номер 1021051403074-2.</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">Rosenberg I.
