Дефицит и недостаточность витамина D являются широко распространенными лабораторными отклонениями в медицине, но их частота при эндокринных заболеваниях в целом не изучена.</p></sec><sec><title>Цель</title><p>Цель. Целью данного исследования было провести сравнительную оценку уровня витамина D у пациентов с сахарным диабетом 2 типа, первичным гиперпаратиреозом (ПГПТ), центральным гиперкортицизмом (болезнью Иценко–Кушинга) и акромегалией.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Общий 25(OH)D определяли иммунохемилюминесцентным методом (лаборатория участвует в программе DEQAS). Все пациенты имели скорость клубочковой фильтрации &gt;60 мл/мин, не принимали добавки витамина D в течение предыдущего месяца.</p></sec><sec><title>Результаты</title><p>Результаты. В исследование были включены 365 пациентов, которые после применения критериев включения/­исключения были разделены на основные группы исследования: 33 пациента с сахарным диабетом 2 типа, 23 пациента с ПГПТ, 68 пациентов с болезнью Иценко–Кушинга, 22 пациента с акромегалией и 141 практически здоровый пациент. Значимо более низкие уровни витамина D были обнаружены у пациентов с сахарным диабетом (14,8 нг/мл), акромегалией (14,9 нг/мл), болезнью Иценко–Кушинга (14,6 нг/мл) и ПГПТ (15,9 нг/мл) по сравнению с группой здоровых пациентов (18,8 нг/мл).</p></sec><sec><title>Заключение</title><p>Заключение. Результаты исследования демонстрируют высокую распространенность дефицита витамина D не только в группах пациентов с хроническими заболеваниями, но и среди практически здоровых пациентов. Необходимы дальнейшие исследования для устранения причин высокого дефицита витамина D при описанных эндокринных заболеваниях.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: Vitamin D deficiency and insufficiency are widespread medical abnormalities, but their frequency in endocrine diseases has generally not been studied.</p></sec><sec><title>AIM</title><p>AIM: To provide a comparative assessment of vitamin D levels in patients with diabetes mellitus type 2, primary hyperparathyroidism (PHPT), central hypercortisolism (Cushing’s disease; CD) and acromegaly.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: Total 25(OH)D was determined using the immunochemiluminescent method (the laboratory participates in the DEQAS program). All patients had GFR &gt; 60 ml/min, no history of use of vitamin D supplementation within previous month.</p></sec><sec><title>RESULTS</title><p>RESULTS: The study included 365 patients who, after applying the inclusion/exclusion criteria, were divided into 5 main research groups: 33 patients with diabetes mellitus type 2, 23 patients with PHPT, 68 patients with CD, 22 patients with acromegaly, and 141 apparently healthy patients. Significantly low levels of vitamin D were found in patients with diabetes mellitus type 2 (14.8 ng/ml), acromegaly (14.9 ng/ml), CD (14.6 ng/ml), and PHPT (15.9 ng/ml) compared with a group of otherwise healthy patients (18.8 ng/ml).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: The results of the study demonstrate a high prevalence of vitamin D deficiency not only in groups of patients with chronic diseases, but also among practically healthy patients. Further studies are needed to address the causes of high vitamin D deficiency in the described endocrine diseases.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>витамин D</kwd><kwd>25(OH)D</kwd><kwd>холекальциферол</kwd><kwd>паратгормон</kwd><kwd>ПТГ</kwd><kwd>акромегалия</kwd><kwd>болезнь Иценко–Кушинга</kwd><kwd>сахарный ­диабет 2 типа</kwd><kwd>первичный гиперпаратиреоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vitamin D</kwd><kwd>25(OH)D</kwd><kwd>cholecalciferol</kwd><kwd>parathyroid hormone</kwd><kwd>PTH</kwd><kwd>acromegaly</kwd><kwd>Cushing’s disease</kwd><kwd>type 2 diabetes mellitus</kwd><kwd>primary hyperparathyroidism</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена по инициативе авторов без привлечения финансирования</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">Пигарова Е.А., Рожинская Л.Я., Белая Ж.Е., и др.
