Костная ткань – это неклассический эндокринный орган, продуцирующий по меньшей мере два соединения с гормональной активностью: фактор роста фибробластов 23 (ФРФ23) и декарбоксилированный остеокальцин. Помимо этого, последние исследования показывают, что специфические белки, вовлеченные в паракринную регуляцию костного ремоделирования, могут быть измерены в образцах сыворотки периферической крови и служить в качестве дополнительных биомаркеров костного обмена.</p></sec><sec><title>Цель</title><p>Цель. Оценить сывороточные уровни биомаркеров, связанных с эндокринной и паракринной функцией костной ткани, у пациентов с болезнью Иценко-Кушинга (БИК) и акромегалией.</p></sec><sec><title>Методы</title><p>Методы. Исследование проведено одномоментно по типу «случай-контроль». В исследование были включены пациенты с установленной активностью БИК и акромегалии, а также здоровые добровольцы, подобранные по возрасту, полу и индексу массы тела (ИМТ). Образцы сывороток крови взяты утром (8–10 ч) натощак и заморожены при температуре -40°C. Для определения уровня исследуемых маркеров (ФРФ23, кофактор (ко-рецептор) Клото, катепсин К, склеростин, P1NP) использованы коммерчески доступные наборы для иммуноферментного анализа. Инсулиноподобный фактор роста-1 (ИФР-1) в сыворотке крови определялся иммунохемилюминесцентным методом, свободный кортизол в вечерней (23:00) слюне – электрохемилюминесцентным методом. Для оценки различий между группами применялись непараметрические варианты дисперсионного анализа – тест Краскела-Уоллиса и критерий Манна-Уитни.</p></sec><sec><title>Результаты</title><p>Результаты. В исследование включены 78 человек (средний возраст 37,60 лет, 95% ДИ 34,75–40,46): 29 пациентов с БИК (группа 1), 22 – с акромегалией (группа 2) и 27 условно здоровых лиц (группа 3), подобранные по полу, возрасту и ИМТ (p=0,432, 0,373 и 0,725 между группами соответственно). Среднее значение свободного кортизола в вечерней слюне у пациентов с БИК и средний уровень ИФР-1 у пациентов с акромегалией были значимо выше, нежели в других группах (p=0,004 и p&lt;0,001 соответственно). У пациентов с акромегалией наблюдалось статистически значимое повышение ФРФ23 в сравнении с контрольной группой (1,13 (0,78;1,49) против 0,78 (0,54;1,09)) и фосфора (1,38 (1,24;1,52) против 1,16 (1,12;1,29)) (p=0,010 и p&lt;0,001 соответственно) наряду с увеличением уровней маркеров костного ремоделирования. У пациентов с БИК были подавлены маркеры костеобразования, однако различий в показателях других биомаркеров обнаружено не было.</p></sec><sec><title>Заключение</title><p>Заключение. Акромегалия приводит к гиперфосфатемии и повышению ФРФ23, что наиболее вероятно объясняется развитием резистентности к ФРФ23, а также к интенсификации костного ремоделирования. При БИК подавлена выработка другого костного гормона, остеокальцина, одновременно со снижением P1NP, что отражает угнетение костеобразования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background: Bone tissue is a non-classical endocrine organ, which produces at least two hormones: fibroblast growth factor 23 (FGF-23) and decarboxylated osteocalcin (OC). In addition to this, recent studies demonstrate that specific proteins involved in the paracrine regulation of bone remodelling can be measured in peripheral serum samples and may serve as additional biomarkers of bone metabolism.</p></sec><sec><title>Aims</title><p>Aims: to evaluate the serum levels of biomarkers related to endocrine and paracrine function of bone tissue in patients with Cushing’s disease (CD) and acromegaly.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: The study was conducted according to the cross-sectional case-control type. Fasting serum samples were taken between 8–10 a.m. from patients with CD, acromegaly and age-, sex- and BMI-matched healthy volunteers and stored at -40° C. Commercially available kits for enzyme-linked immunosorbent assay (ELISA) were used to determine the serum levels of FGF-23, co-factor (co-receptor) Klotho, cathepsin K, sclerostin, P1NP. Insulin-like growth factor-1 (IGF-1) was measured by the immunochemiluminescence assay, late-night (11 p.m.) salivary cortisol (LNSC) was evaluated using the electrochemiluminescence method. Non-parametric tests (the Kruskal-Wallis test and the Mann-Whitney test) were used to assess the differences between the groups of patients.</p></sec><sec><title>Results</title><p>Results: The study includes 78 patients, (37.6 years old, 95% CI 34.75–40.46): 29 patients with CD (group 1), 22 – with acromegaly (group 2), and 27 healthy individuals (group 3), matched by sex, age and BMI (p = 0.432, 0.373 and 0.725 between groups, respectively). LNSC in patients with CD and IGF-1 in patients with acromegaly were significantly higher compared to the control group (p = 0.004 and p &lt;0.001, respectively). In patients with acromegaly, a statistically significant increase in FGF-23 (1.13 (0.78;1.49) vs 0.78 (0.54;1.09)) and phosphorus (1.38 (1.24;1.52) vs 1.16 (1.12;1.29)) (p = 0.01 and p &lt;0.001, respectively) was observed along with increased levels of bone remodelling markers. In patients with CD, bone formation markers were suppressed, but differences in the levels of other biomarkers could not be identified.</p></sec><sec><title>Conclusions</title><p>Conclusions: Acromegaly leads to hyperphosphatemia and increase in FGF-23, which is most likely due to the development of resistance to FGF-23, and the intensification of bone remodelling. With CD, another bone hormone, osteocalcin, is suppressed along with the suppression of P1NP.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>маркеры костного обмена</kwd><kwd>гиперфосфатемия</kwd><kwd>фактор роста фибробластов-23</kwd><kwd>болезнь Иценко−Кушинга</kwd><kwd>акромегалия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bone turnover (markers)</kwd><kwd>hyperphosphatemia</kwd><kwd>fibroblast growth factor-23 (fgf-23)</kwd><kwd>cushing’s disease</kwd><kwd>acromegaly</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">Guntur AR, Rosen CJ.
