Первичный гиперпаратиреоз (ПГПТ) — распространенное эндокринное заболевание, возникающее в результате гиперсекреции паратиреоидного гормона (ПТГ) опухолью околощитовидных желез (ОЩЖ). Единственным радикальным методом лечения ПГПТ является паратиреоидэктомия (ПТЭ). Частота гипокальциемии после ПТЭ может достигать 46% случаев. При этом значимое снижение уровня кальция в сыворотке крови ассоциировано как с локальными, так и с генерализованными судорогами тонико-клонического типа, жизнеугрожающими нарушениями сердечного ритма. Сопутствующий дефицит витамина D может усугубить тяжесть течения ПГПТ и способствовать развитию в раннем послеоперационном периоде «синдрома голодных костей», характеризующегося тяжелой и стойкой гипокальциемией вследствие резкого снижения уровня ПТГ и усиленного «оттока» кальция в обедненную костную ткань.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Оценить наличие ассоциации и показатели силы связи предоперационной терапии колекальциферолом с развитием гипокальциемии через 1–3 дня после ПТЭ у больных с ПГПТ.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ. Обследование проводилось в ФГБУ «НМИЦ эндокринологии» Минздрава России в 1993–2010 или 2017–2020 гг. Критериями включения было наличие у пациентов ПГПТ и показаний к ПТЭ, сывороточный уровень 25-гидроксивитамина D (25(OH)D)&lt;20 нг/мл и уровень общего кальция в сыворотке &lt;3 ммоль/л. Критерием исключения являлась терапия препаратами, влияющими на кальциево-фосфорный обмен, — цинакальцетом, деносумабом или бисфосфонатами (как в виде монотерапии, так и в составе комбинированной терапии).</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. В исследование было включено 117 пациентов, из них 110 (94%) женщин и 7 (6%) мужчин. Медиана и квартили возраста составили 58 [49; 65] лет. 21 (18%) пациент принимал колекальциферол от 2 недель до 2 месяцев до ПТЭ в дозе, соответствующей восполнению дефицита витамина D; 96 (82%) пациентов не принимали колекальциферол. Группы пациентов, принимающих и не принимающих колекальциферол, были сопоставимы по антропометрическим (пол, возраст на момент операции), предоперационным клиническим (снижение МПК) и лабораторным показателям (ПТГ, общий кальций, фосфор, ЩФ, ОК, СТХ-1, 25(OH)D). Послеоперационная гипокальциемия статистически значимо реже наблюдалась у пациентов, принимающих колекальциферол (10% против 63%, p&lt;0,001, ТКФ2). Прием колекальциферола отрицательно ассоциирует с развитием гипокальциемии (ОР=0,15, 95% ДИ (0,03; 0,51)).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. Прием колекальциферола от 2 недель до 2 месяцев перед ПТЭ снижает риск послеоперационной гипокальциемии у пациентов с ПГПТ в 2–33 раза.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: Primary hyperparathyroidism (PHPT) is a endocrine disorder characterized by excessive secretion of parathyroid hormone (PTH) from parathyroid gland tumors. Parathyroidectomy (PTE) is the main treatment for PHPT, but it can lead to hypocalcemia in up to 46% of cases. Hypocalcemia is associated with seizures and life-threatening cardiac arrhythmias, and vitamin D deficiency can exacerbate PHPT severity and contribute to «hungry bones syndrome,» resulting in severe and persistent postoperative hypocalcemia.</p></sec><sec><title>AIM</title><p>AIM: To evaluate the association and determine the strength of the relationship between preoperative cholecalciferol therapy and the occurrence of hypocalcemia within 1–3 days after PTE in patients with PHPT.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: The study was conducted at the Endocrinology Research Centre, during the periods of 1993–2010 and 2017–2020. The inclusion criteria consisted of patients diagnosed with PHPT who required PTE, had a serum 25-hydroxyvitamin D (25(OH)D) level below 20 ng/mL, and a serum total calcium level below 3 mmol/L. The exclusion criterion was the use of medications that affect calcium-phosphorus metabolism, including cinacalcet, denosumab, or bisphosphonates, either as monotherapy or as part of combination therapy.</p></sec><sec><title>RESULTS</title><p>RESULTS: There were 117 patients, including 110 (94%) females and 7 (6%) males. The median age and interquartile range were 58 [49; 65] years. Among the participants, 21 (18%) received cholecalciferol supplementation for a duration of 2 weeks to 2 months prior to PTE, aiming to address vitamin D deficiency. The remaining 96 (82%) participants did not receive ­cholecalciferol supplementation. Both groups, i.e., participants receiving cholecalciferol and those who did not, were similar in terms of anthropometric factors (sex and age at the time of surgery), preoperative clinical characteristics (BMD decrease), and laboratory parameters (PTH, total calcium, phosphorus, ALP, OC, CTX-1, and 25(OH)D levels). The occurrence of postoperative hypocalcemia was significantly lower in participants who received cholecalciferol supplementation (10% vs. 63%, p&lt;0,001, FET2). Cholecalciferol intake showed a negative association with hypocalcemia development (RR=0,15, 95% CI (0,03; 0,51)).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: Preoperative cholecalciferol supplementation for 2 weeks to 2 months before PTE reduces the risk of postoperative hypocalcemia in patients with PHPT by 2–33 times.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>первичный гиперпаратиреоз</kwd><kwd>гипокальциемия</kwd><kwd>колекальциферол</kwd><kwd>паратиреоидэктомия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary hyperparathyroidism</kwd><kwd>hypocalcemia</kwd><kwd>cholecalciferol</kwd><kwd>parathyroidectomy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья опубликована в рамках выполнения государственного задания «Оптимизация российского электронного реестра пациентов с первичным гиперпаратиреозом» № НИОКТР 121030100032-7 при финансовой поддержке Министерства здравоохранения Российской Федерации.</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">Duan K, Gomez Hernandez K, Mete O.
