МЭН1-ассоциированный гиперпаратиреоз (мПГПТ) – редкая наследственная форма первичного гиперпаратиреоза (ПГПТ), развивающаяся  вследствие герминальной мутации в гене MEN1. Доступные данные об особенностях костного обмена в данной группе скудны и противоречивы, что обусловлено орфанной природой заболевания, недостаточной выявляемостью заболевания ввиду ограниченности применения генетического скрининга и неоднородностью оцениваемых выборок.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Изучить фенотипические особенности верифицированного МЭН1-ассоциированного ПГПТ, включая опосредованные им костные нарушения, в популяции пациентов Всероссийского онлайн регистра</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ. Проведено всероссийское, многоцентровое, неинтервенционное, наблюдательное, одномоментное исследование особенностей костного метаболизма  в группе генетически верифицированного мПГПТ (N=86) и спорадического гиперпаратиреоза (сПГПТ)  (N=3599) в активной фазе ПГПТ.  Оценивались основные показатели кальциево-фосфорного обмена, а также минеральная плотность костной ткани (МПК) по Z-критерию в поясничном отделе позвоночника, бедренной и лучевой костях.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. По данным Всероссийского регистра пациенты с мПГПТ имеют сопоставимые со спорадической формой заболевания параметры кальций-фосфорного обмена при более высоком уровне общего (р=0,019) и ионизированного кальция (р=0,010). Частота изолированных костных осложнений  (38% против 27%; р=0,081,) и патологии почек (16% против 18%; р=0,086) сопоставима в обеих группах. К особенностям костного фенотипа при мПГПТ, после исключения возраст-ассоциированных факторов, относится бо́льшая частота снижения МПК относительно возрастных значений в шейке бедренной кости (р=0,009).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. По данным Всероссийского регистра пациенты с мПГПТ по сравнению со сПГПТ характеризуются сопоставимыми отклонениями в показателях фосфорно-кальциевого обмена, а также сопоставимой частотой костных и висцеральных осложнений. В подгруппе молодых пациентов с мПГПТ отмечены бо́льшая частота снижения МПК относительно возрастных значений в шейке бедренной кости.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: MEN1-related hyperparathyroidism (mPHPT) is a rare inherited form of primary hyperparathyroidism (PHPT) that is caused by a germline mutation in the MEN1 gene. The available data on bone phenotypes in mPHPT are scarce and contradictory due to the orphan nature of the disease, the under-recognition of the disease due to the limited use of genetic screening, and the heterogeneity of the samples evaluated.</p></sec><sec><title>AIM</title><p>AIM: To evaluate the phenotypic features of verified MEN1-associated primary hyperparathyroidism, including associated bone complications, according to data from Russian register of primary hyperparathyroidism</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: A nationwide, multicenter, non-interventional, observational, cross-sectional study was conducted to investigate the characteristics of bone metabolism in a group of verified mPHPT (N=86) and sporadic hyperparathyroidism (sPHPT) (N=3599) in the active phase of PHPT. The main parameters of calcium-phosphorus metabolism were evaluated, as well as bone mineral density (BMD) using the Z-score in the lumbar spine, femur, and radius.</p></sec><sec><title>RESULTS</title><p>RESULTS: According to the Russian registry of hyperparathyroidism, patients with mPHPT have the same parameters of calcium-phosphorus metabolism as the sporadic form of the disease, with higher levels of total (p=0.019) and the lower level of ionized calcium (p=0.010). The prevalence of isolated bone complications (38% vs. 27%; p=0.081) and renal pathology (16% vs. 18%; p=0.086) was comparable in both groups. After exclusion of age-related factors, the bone phenotype of mPHPT is characterized by a greater frequency of BMD loss in the femur neck (p=0.009).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: According to data from the Russian Registry of Hyperparathyroidism, patients with mPHPT and sPHPT are characterized by comparable deviations in the main parameters of phosphorus-calcium metabolism, except for total and ionized calcium, as well as the frequency of bone and visceral complications. A higher frequency of BMD loss at the femoral neck was observed in the subgroup of young patients with mPHPT.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Первичный гиперпаратиреоз</kwd><kwd>синдром множественных эндокринных неоплазий 1 типа</kwd><kwd>минеральная плотность костной ткани</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary hyperparathyroidism</kwd><kwd>multiple endocrine neoplasia type 1</kwd><kwd>bone mineral density</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена на основании результатов, полученных в ходе реализации Соглашения о предоставлении гранта в форме субсидий из федерального бюджета на осуществление государственной поддержки создания и развития научных центров мирового уровня, выполняющих исследования и разработки по приоритетам научно-технологического развития от 20 апреля 2022 года № 075-15- 2022-310.</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">Al-Salameh A, Cadiot G, Calender A, Goudet P, Chanson P.
