Проявляются эти изменения развитием вторичного гиперпаратиреоза (повышением сывороточной концентрации паратиреоидного гормона на фоне гипокальциемии, гиперфосфатемии), нарушением метаболизма витамина D, минерализации и объема костной ткани, а также внескелетной кальцификацией. Снижение сывороточной концентрации паратиреоидного гормона с гиперкальциемией подозрительно в отношении адинамической костной болезни, но в то же время требует расширенного дифференциально-диагностического поиска (в частности, в отношении метастатического процесса). Одной из редких причин гиперкальциемии является нарушение метаболизма витамина D, в частности, наличие дефекта 24-гидроксилазы (CYP24A1). Мы представляем случай нетипичного течения минеральных и костных нарушений при хронической болезни почек у пациентки, получающей заместительную почечную терапию программным гемодиализом, c установленным дефектом CYP24A1.</p></abstract><trans-abstract xml:lang="en"><p>Patients with chronic kidney disease are characterized by the development of mineral disorders due to a decrease in the number of functioning nephrons. These changes manifest by the development of secondary hyperparathyroidism (the overproduction of intact parathyroid hormone (PTH) associated with the serum hypocalcemia, hyperphosphatemia), dysfunctional vitamin D metabolism, bone mineralization and also extraosseous calcifications. Decreased serum PTH levels associated with hypercalcemia are suspicious for adynamic bone disease, but at the same time requires an extended differential diagnostic search (e.g. metastatic processes). One of the rare causes of hypercalcemia is a defect in 24-hydroxylase (CYP24A1). We present a case of a patient on hemodialysis with atypical secondary hyperparathyroidism and an established CYP24A1 defect.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гиперкальциемия</kwd><kwd>вторичный гиперпаратиреоз</kwd><kwd>гемодиализ</kwd><kwd>витамин D 24-гидроксилаза</kwd><kwd>МКН-ХБП</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypercalcemia</kwd><kwd>secondary hyperparathyroidism</kwd><kwd>renal dialysis</kwd><kwd>vitamin D 24-hydroxylase</kwd><kwd>CKD-MBD</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа проведена в рамках выполнения гранта РНФ № 19-15-00243 «Нарушения метаболизма витамина D, обусловленные эндокринопатиями»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Elias RM, Dalboni MA, Coelho ACE, et al.
