До настоящего времени отсутствовал эффективный способ прогнозирования развития гипокальциемии после паратиреоидэктомии (ПТЭ) у пациентов с первичным гиперпаратиреозом (ПГПТ). Гипокальциемия может сопровождаться миалгиями, генерализованными судорогами вплоть до тетании, нарушениями сердечного ритма. Для снижения рисков гипокальциемии после ПТЭ на предоперационном этапе может проводиться терапия колекальциферолом. Однако, пациентам с предоперационной концентрацией общего кальция выше 3 ммоль/л не назначают витамин D в связи с угрозой прогрессирования гиперкальциемии. Несмотря на имеющиеся данные об относительной безопасности насыщения витамином D пациентов с мягкой гиперкальциемией, данная терапия проводится не во всех случаях, что вероятно обусловлено отсутствием инструмента для оценки постоперационных рисков.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Построение математической модели и программного инструмента для прогнозирования развития гипокальциемии на 1-3 сутки после радикальной ПТЭ у пациентов с ПГПТ с использованием демографических, клинических и лабораторных факторов, а также факта приема предоперационной лекарственной терапии.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ. Ретроспективное исследование включало 478 пациентов с ПГПТ, которым была проведена ПТЭ в 1993-2010гг. и 2018-2020гг. в ГНЦ ФГБУ «НМИЦ эндокринологии» Минздрава России. Анализировались следующие показатели: пол, возраст, лабораторные показатели до начала приема антирезорбтивной лекарственной терапии (деносумаб, бисфосфосфонаты) и кальцимиметиков - ПТГ, общий кальций, фосфор, лабораторные показатели, косвенно отражающие состояние костной ткани (остеокальцин (ОК), щелочная фосфатаза (ЩФ), С-концевой телопептид коллагена I типа) и 25(ОН) витамин D (25(OH)D), минеральная плотность костной ткани (МПК) по данным рентгеновской денситометрии, наличие низкоэнергетических переломов (НЭП) в анамнезе и принимаемая на дооперационном этапе лекарственная терапия: деносумаб;  бисфосфонаты; цинакальцет; колекальциферол. Для построения прогностической модели развития послеоперационной гипокальциемии использовали категориальный градиентный бустинг (CatBoost).</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Частота тяжелого остеопороза выше в группе пациентов с послеоперационной гипокальциемией по сравнению с группой пациентов с нормальной послеоперационной сывороточной концентрацией кальция (27% против 15%), а частота предоперационного приема колекальциферола в данной группе ниже (8% против 25%). С целью прогнозирования развития послеоперационной гипокальциемии построена модель на основе CatBoost с использованием 13 предикторов: пол, возраст, ПТГ, кальций общий, фосфор, ЩФ, ОК, снижение МПК, 25(OH)D, прием колекальциферола, бисфосфонатов, деносумаба, цинакальцета.

Hypocalcemia may be accompanied by myalgia, generalized seizures up to tetany, and arrhythmias. Hypocalcemia following PTE can be prevented by preoperative cholecalciferol supplementation. However, patients with severe hypercalcemia above 3 mmol/L do not receive vitamin D due to the risk of hypercalcemia progression. Despite the existing data showing the safety of cholecalciferol therapy in case of mild elevation of serum calcium, not all patients are prescribed vitamin D supplementation, probably due to the lack of a suitable tool to assess the postoperative hypocalcemia risks.</p></sec><sec><title>AIM</title><p>AIM: To design a mathematical model and a software tool for predicting hypocalcemia 1–3 days post-PTE in PHPT patients using the patient’s demographic and clinical data, laboratory test results and preoperative therapy status.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: This retrospective study included 478 PHPT patients diagnosed with adenomas and carcinomas of the parathyroid gland (PTG) who underwent radical PTE between 1993–2010 or 2018–2020 at the Endocrinology Research Centre. The following parameters were analyzed: sex; age; laboratory markers prior to calcimimetic and antiresorptive therapy: PTH, total calcium, phosphorus; osteocalcin (OC), alkaline phosphatase (ALP), C-terminal telopeptide of type 1 collagen. Also we analyzed 25-hydroxyvitamin D (25(OH)D); bone mineral density (BMD) measured by X-ray densitometry; medical history of low-energy fractures; preoperative therapy with denosumab, bisphosphonates, cinacalcet, cholecalciferol. Categorical gradient boosting (CatBoost) was built to predict the risk of postoperative hypocalcemia.</p></sec><sec><title>RESULTS</title><p>RESULTS: The prevalence of severe osteoporosis is higher in the postoperative hypocalcemia group compared to the nonhypocalcemia group (27% vs. 15%), wherein the frequency of preoperative administration of cholecalciferol in this group is lower (8% vs. 25%). A CatBoost model was built to predict postoperative hypocalcemia using 13 predictors (sex, age, PTH, serum total calcium, phosphorus, OC, BMD reduction, 25(OH)D, administration of cholecalciferol, bisphosphonates, denosumab, and cinacalcet. The proposed model http://194.87.111.169/hypocalcemia for post-PTE hypocalcemia in PHPT patients achieved the following metrics: positive predictive value 73.3%-86.7%; negative predictive value 74.9%-89.3%.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: The model can be used to choose the appropriate preand postoperative approaches for patients who undergo rPTE.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>первичный гиперпаратиреоз</kwd><kwd>паратиреоидэктомия</kwd><kwd>гипокальциемия</kwd><kwd>кальций</kwd><kwd>паратиреоидный гормон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary hyperparathyroidism</kwd><kwd>parathyroidectomy</kwd><kwd>hypocalcemia</kwd><kwd>calcium</kwd><kwd>parathyroid hormone</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">Мокрышева Н.Г.
