Под нашим наблюдением находилось 87 пациенток с достоверным диагнозом РА. Средний возраст пациенток составил 67,4±6,9 (61,7-73,4) лет. Длительность РА составила от 0,2 до 33 лет (9 [4-16]). Средний уровень β-Cross Laps у больных РА составил 0,684 [0,40-0,78] нг/мл, повышение уровня верхней границы нормы наблюдалось у 28 (32,2%) пациенток. Достоверной зависимости между уровнем β-Cross Laps и возрастом, а также ростом, весом и ИМТ пациенток выявлено не было. Выявлена связь между концентрацией β-Cross Laps и активностью заболевания (K-W χ2=3,318, p=0,042), рентгенологической стадией (K-W χ2=2,960, p=0,036), функциональным классом (K-W χ2=3,639, p=0,030) и уровнем С-реактивного белка (СРБ) (ρ=3,1907; p= 0,037).</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to investigate the relationship between the serum level of C-terminal telopeptides of type I collagen and clinical and laboratory features of rheumatoid arthritis in elderly female patients. We observed 87 patients with a reliable diagnosis of RA. The average age of the patients was 67.4±6.9 (61.7-73.4) years. The duration of RA ranged from 0.2 to 33 years (9 [4-16]). The average level of β-Cross Laps in patients with RA was 0.684 [0.40-0.78] ng/ml, an increase in the upper limit of the norm was observed in 28 (32.2%) patients. No significant relationship was found between the level of β-Cross Laps and age, as well as height, weight and BMI of the patients. A relationship was found between the concentration of β-Cross Laps and disease activity (K-W χ2=3.318, p=0.042), radiographic stage (K-W χ2=2.960, p=0.036), functional class (K-W χ2=3.639, p=0.030) and CRP level (ρ=3.1907; p= 0.037).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>С-телопептиды коллагена I типа</kwd><kwd>β-Cross laps</kwd><kwd>CTX-1</kwd><kwd>ревматоидный артрит</kwd><kwd>остеопороз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>C-telopeptides of type I collagen</kwd><kwd>β-Cross laps</kwd><kwd>CTX-1</kwd><kwd>rheumatoid arthritis</kwd><kwd>osteoporosis</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">Smolen JS, Aletaha D, McInnes IB.
