Ревматическая кахексия – характерное для ревматоидного артрита патологическое состояние, которое проявляется снижением массы лишенных жира тканей при повышенном или нормальном индексе массы тела. К числу компонентов ревматической кахексии относится уменьшение костной массы. Важным структурным компонентом костной ткани является участвующий в процессе гликопротеин фетуин-А. Цель исследования – изучить распространенность ревматической кахексии, а также взаимосвязь сывороточного уровня фетуина-А и показателей композитного состава тела. Материал и методы. В исследование включено 110 пациентов с ревматоидным артритом (8 мужчин и 102 женщины), которым была проведена двухэнергетическая рентгеновская абсорбциометрия с программой Total Body. Диагноз ревматической кахексии выставлялся при индексе безжировой массы ниже 10-го процентиля и индексе жировой массы более 25-го процентиля для данного возраста. Сывороточный уровень фетуина-А определялся методом ИФА. Результаты и их обсуждение. Ревматическая кахексия выявлена у 25 пациентов (22,7 %). Согласно данным литературы, у таких больных повышен риск развития метаболического синдрома, артериальной гипертензии и смертности. Сывороточный уровень фетуина-А положительно коррелировал с массой костной ткани в правой и левой нижних конечностях, туловище, гиноидной области, обеих нижних конечностях и во всем теле, с уровнем достоверности p &lt; 0,05 по всем зонам. Статистически значимых взаимосвязей с другими показателями не выявлено. Динамическое снижение содержания фетуина-А у пациентов с ревматоидным артритом может сопровождаться потерей костной массы, что требует своевременной коррекции терапевтического подхода. Заключение. Почти четверть пациентов с ревматоидным артритом имеют ревматическую кахексию. Сывороточный уровень фетуина-А положительно коррелирует с костной массой в нижних конечностях, корпусе, гиноидной области и во всем теле.</p></abstract><trans-abstract xml:lang="en"><p>Background. Rheumatoid cachexia is a pathological condition which appears in patients with rheumatoid arthritis with low fat-free mass and normal or high body mass index. Bone mass loss is one of the components of rheumatoid cachexia. Fetuin-A, a major noncollagen protein of bone tissue, regulates bone remodeling. Aim of the study was to investigate the prevalence of rheumatoid cachexia and the association of serum fetuin-A level with body composition components in patients with rheumatoid arthritis. Material and methods. 110 patients (8 male and 102 female) with rheumatoid arthritis were enrolled in our study. Serum fetuin-A level was determined by ELISA. Dual-energy X-ray absorptiometry with Total Body program was performed. The diagnosis of rheumatoid cachexia was based on the next criteria: fat-free mass index less than 10th percentiles with fat mass index above 25th percentiles. Results and discussion. We observed rheumatoid cachexia in 25 patients (22,7 %). According to the literature, such patients have an increased risk of developing metabolic syndrome, arterial hypertension and mortality. Positive significant (p &lt; 0,05) correlations were observed between serum fetuin-A levels and right and left lower limb, trunk, gynoid region, both lower limbs and total body bone mass. No statistically significant relationships with other indicators were identified. Fetuin-A negative dynamic in patients with rheumatoid arthritis may be accompanied by the loss of bone mass, which requires the improvement of therapeutic approach. Conclusions. Almost a quarter of patients with rheumatoid arthritis have rheumatic cachexia. Positive correlation between serum fetuin-A levels and lower limbs, trunk, gynoid region and total body bone mass was observed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>ревматическая кахексия</kwd><kwd>композитный состав тела</kwd><kwd>фетуин-А</kwd><kwd>костная ткань</kwd><kwd>тощая ткань</kwd><kwd>жировая ткань</kwd><kwd>индекс жировой массы</kwd><kwd>индекс безжировой массы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>rheumatoid cachexia</kwd><kwd>body composition</kwd><kwd>fetuin-A</kwd><kwd>bone tissue</kwd><kwd>lean tissue</kwd><kwd>fat tissue</kwd><kwd>fat mass index</kwd><kwd>fat-free mass index</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">Lee D.M., Weinblatt M.E.
