Пиридинолин (PYD) и С-концевой телопептид коллагена I типа (β-CrossLaps) образуются при распаде костной ткани и являются одними из специфичных маркеров костной резорбции. Витамин D принимает участие в метаболизме костной ткани, его дефицит ускоряет процессы распада костной ткани. Материал и методы. Обследовано 60 женщин с ОП (30 русской и 30 бурятской национальностей) в возрасте от 50 до 80 лет, в контрольную группу вошли 20 женщин (10 русской и 10 бурятской национальностей). В сыворотке крови определяли концентрацию пиридинолина, С-концевого телопептида коллагена I типа (β-CrossLaps) и 25-гидроксивитамина D (25(ОН)D). Результаты и их обсуждение. Уровень β-CrossLaps у женщин с ОП был выше, а 25(ОН)D – ниже, чем у лиц контрольной группы. У обследованных русской национальности установлены корреляционные взаимосвязи между содержанием β-CrossLaps и индексом массы тела менее 20 кг/см2 , частыми падениям и абсолютным 10-летним риском перелома шейки бедренной кости; между уровнем 25(ОН)D и наследственным анамнезом ОП. У пациенток бурятской национальности выявлена взаимосвязь между концентрацией пиридинолина и курением, 25(ОН) D и низкой физической активностью, С-концевого телопептида и абсолютным риском основных остеопоротических переломов. Установлено, что независимым предиктором развития переломов у русских женщин является содержание β-CrossLaps (β = 0,678, р = 0,04), у буряток – концентрация пиридинолина (β = –0,38, р = 0,04) и β-CrossLaps (β = 0,671, р = 0,01). Заключение. Определение уровня пиридинолина, β-CrossLaps и 25(OH)D можно использовать в диагностике ОП и переломов у резидентов Забайкальского края в дополнение к оценке факторов риска и минеральной плотности костной ткани. </p></abstract><trans-abstract xml:lang="en"><p>Osteoporosis (OP) is a metabolic bone disease, characterized by a decrease of bone mineral density, leading to the development of low-energy fractures. Serum pyridinoline (PYD) and C-terminal cross-linking telopeptide type I (β-CrossLaps) are among the specific markers of bone resorption. Vitamin D is involved in the metabolism of bone tissue, its deficiency accelerates the processes of bone tissue breakdown. Material and methods. 60 women with osteoporosis were studied (30 Russian and 30 Buryat nationalities) aged 50 to 80 years; the control group included 20 women (10 Russian and 10 Buryat nationalities). Serum bone resorption markers, namely pyridinoline and β-CrossLaps, 25-hydroxyvitamin D (25(OH)D) were measured using immunoassays. Results and discussion. The level of β-CrossLaps was higher and the content of 25(OH)D was lower in women with osteoporosis compared to the control group. There was a positive relationship between β-CrossLaps concentration and body mass index &lt; 20 kg/cm2 , frequent falls, and a hip fracture, between the level of 25(OH)D and hereditary history of osteoporosis in Russian women. There was a positive relationship between Serum pyridinoline and smoking, between 25(OH)D and low physical activity, β-CrossLaps and the major osteoporotic fractures in Buryat women. It was found that the β-CrossLaps is an independent predictor of the development of fractures in Russian women (β = 0.678, p = 0.04). In Buryat women, independent predictors of fractures are pyridinoline (β = –0.38, p = 0.04) and β-CrossLaps (β = 0.671, p = 0.01). Conclusions. The systemic markers of bone resorption (pyridinoline, β-CrossLaps) and 25(OH)D can be used in the diagnosis of osteoporosis and fractures in residents of the Trans-Baikal Region in addition to risk factor assessment and bone mineral density measurement. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>остеопороз</kwd><kwd>пиридинолин</kwd><kwd>С-концевой телопептид коллагена I типа</kwd><kwd>25-гидроксивитамин D</kwd><kwd>факторы риска</kwd><kwd>низкоэнергетические переломы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>osteoporosis</kwd><kwd>pyridinoline</kwd><kwd>C-terminal cross-linking telopeptide type I</kwd><kwd>25-hydroxyvitamin D</kwd><kwd>risk  factors</kwd><kwd>low-energy fractures</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">Установлено увеличение концентрации β-CrossLaps и снижение уровня 25(ОН)D у женщин с ОП.</mixed-citation><mixed-citation xml:lang="en">Clinical guidelines.
