На сегодняшний день остается открытым вопрос: является ли остеопороз проявлением основного заболевания, осложнением, коморбидным состоянием или мультиморбидным состоянием у больных АС? Полагают, что нарушение метаболизма костной ткани вследствие воспалительного процесса, который лежит в основе АС, увеличивает риск развития ОП и может рассматриваться как своеобразный показатель «тяжести» заболевания и активности воспаления. Эти данные также позволяют рассматривать ОП при АС как одно из проявлений болезни. Статистические данные за последнее десятилетие достоверно свидетельствуют о высокой частоте снижения минеральной плотности костной ткани (МПК) у больных АС. Снижение МПК при АС может быть обусловлено разнообразными факторами: возрастом, полом, длительностью АС, формой заболевания, активностью воспалительного процесса, наличием внеаксиальных и внескелетных проявлений, тяжестью функциональных нарушений, дефицитом витамина Д. Ведущим патогенетическим звеном развития ОП является воспаление, значительную роль в развитии которого играют провоспалительные цитокины. В основе диффузной потери костной массы при АС также лежит дисбаланс в системе RANK/RANKL/OPG, этот патогенетический механизм считается одним из ведущих в развитии ОП при АС. В последние годы в литературе встречается новый термин - сарко-остеопороз (сарко-остеопения) - сочетание саркопении и остеопороза (остеопении), что приводит к значительному повышению риска падений и возникновению низкоэнергетических переломов, росту заболеваемости и летальности. Учитывая хронический характер и бессимптомное течение ОП, задачей врачей, работающих с данной группой больных, является активный поиск ОП, сарко-остеопороза/остеопении с использованием всех доступных диагностических методик с целью оценки риска развития данного состояния с последующей коррекцией факторов риска и проводимого медикаментозного лечения</p></abstract><trans-abstract xml:lang="en"><p>Currently, rheumatologists consider osteoporosis as a complication of ankylosing spondylitis, however, in recent years, it is discussed as a comorbidity but not a complication. Disturbances in bone tissue metabolism provoked by ankylosing spondylitis-related inflammation increase the risk of osteoporosis and suggest osteoporosis as a manifestation of ankylosing spondylitis. Further, patients with ankylosing spondylitis are frequently diagnosed with a reduction of bone mineral density, the extent of which is determined by gender, age, type and duration of ankylosing spondylitis, severity of the inflammation, vitamin D deficiency, and extraskeletal calcification. Inflammation defined by excessive levels of pro-inflammatory cytokines plays a leading role in the development of osteoporosis. Another reason of bone loss in patients with ankylosing spondylitis is dysregulated balance in RANK/RANKL/OPG pathway. A combination of sarcopenia and osteopenia/osteoporosis (sarco-osteopenia/sarco-osteoporosis) results in a significant increase in the risk of low-energy fractures affecting quality of life, morbidity, and mortality in this patient category. Therefore, an active screening for osteoporosis/sarco-osteopenia/sarco-osteoporosis followed by the respective secondary prevention and treatment is of particular importance</p></trans-abstract><kwd-group xml:lang="ru"><kwd>анкилозирующий спондилит</kwd><kwd>остеопороз</kwd><kwd>ankylosing spondylitis</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">Гордеев А.В., Галушко Е.А., Насонов Е.Л.
