Обследованы 182 женщины с подтвержденным диагнозом РА (медиана возраста – 61 [53; 66] год). Проведены клинико-лабораторное обследование, включая определение МК в сыворотке крови, и двухэнергетическая рентгеновская абсорбциометрия в стандартных областях измерения и всего тела.</p></sec><sec><title>Результаты</title><p>Результаты. Медиана уровня МК в обследованной группе составила 258,5 [198,0; 309,5] мкмоль/л. При сравнительном анализе в зависимости от квартиля уровня МК выявлены статистически значимые различия между группами по возрасту, индексу массы тела, аппендикулярному мышечному индексу (АМИ), общей мышечной массе (ОММ) и общему мышечному индексу (ОМИ). Методом прямой пошаговой регрессии установлено, что уровень МК у женщин с РА не связан с величиной МПК во всех областях измерения (р&gt;0,05), но коррелировал со всеми количественными показателями мышечной массы (АМИ – β=0,29; ОММ – β=0,37; ОМИ – β=0,35; р&lt;0,001).</p></sec><sec><title>Заключение</title><p>Заключение. У женщин с РА не выявлено независимой связи между уровнем МК и МПК в стандартных областях измерения.

A total of 182 women with confirmed RA (median age 61 [53; 66] years) were examined.

The UA level in the examined group was 258.5 [198.0; 309.5] μmol/l. A comparative analysis depending on the UA level quartile revealed significant differences between the groups in age, body mass index, appendicular muscle index (AMI), total muscle mass (TMM), and total muscle index (TMI). The direct stepwise regression method showed that the UA level in women with RA was not associated with the BMD value in all measurement areas (p&gt;0.05), but was associated with all quantitative indices of muscle mass (with AMI – β=0.29; with TMM – β=0.37; with TMI – β=0.35; p&lt;0.001).</p></sec><sec><title>Conclusion</title><p>Conclusion. In women with RA, no independent association was found between UA level and BMD in standard measurement areas.
