Благодаря широкому распространению скрининга на остеопороз, в последние 10—20 лет в мире началась «новая эра» диагностики ПГПТ, когда специалисты стали обнаруживать пациентов на стадии изолированного повышения уровня паратгормона со стойко нормальным уровнем кальция в крови и отсутствием вторичных причин гиперпаратиреоза. Этот феномен был назван нормокальциемическим первичным гиперпаратиреозом (нПГПТ); его распространенность варьирует от 0,4 до 16,7%. Столь широкий разброс данных связан с отсутствием единых диагностических критериев. Клиническая картина и естественное течение заболевания мало изучены, и до сих пор непонятно, является ли нПГПТ отдельной нозологической единицей или представляет собой раннюю стадию гиперкальциемического ПГПТ. Ряд исследований показал, что осложнения нПГПТ (остеопороз и мочекаменная болезнь) сходны с таковыми манифестной формы ПГПТ, несмотря на сохранение нормокальциемии. Однако пациенты чаще всего наблюдались в специализированных центрах по поводу снижения костной массы или нефролитиаза, поэтому частота осложнений у них может быть несколько завышена. Также имеются противоречивые данные о повышении при этой патологии риска сердечно-сосудистых заболеваний.</p><p>Нормокальциемический ПГПТ как новая клиническая нозология был впервые официально признан на III Международном консенсусе по лечению асимптомного ПГПТ в 2008 г., но в настоящий момент не существует общих рекомендаций по его лечению. Некоторые исследования показали эффективность медикаментозной терапии, а также улучшение показателей минеральной плотности костной ткани у таких пациентов после паратиреоидэктомии. По мнению экспертов IV Международного консенсуса 2014 г., нПГПТ остается одной из ключевых тем для дальнейших исследований.</p></abstract><trans-abstract xml:lang="en"><p>During the last century, primary hyperparathyroidism (PHPT) passed from the category of rare severe diseases to a common endocrine disorder with a prevalence of mild forms. Over the last 10—20 years, widespread screening for osteoporosis has led to the «new era» in diagnosis of PHPT when patients are diagnosed at the stage of an isolated elevated parathyroid hormone with stable normal serum calcium levels and the absence of secondary causes of hyperparathyroidism. This phenomenon was called normocalcemic primary hyperparathyroidism (nPHPT); according to the literature data, its prevalence varies from 0.4 to 16.7% due to the lack of unified diagnostic criteria. The clinical picture and natural history of the disease are poorly explored, and it is still unclear if nPHPT is a separate disease entity or if it is an early stage of hypercalcemic PHPT. A number of studies have shown that complications of nPHPT (osteoporosis and urolithiasis) are similar to those of the symptomatic form of PHPT despite stable normocalcemia. However, these patients were often referred to specialized metabolic centers due to a decrease in the bone mass or nephrolithiasis, therefore the rate of complications in them may be overestimated. There are also controversial data on an increased risk of cardiovascular diseases due to metabolic disorders in this pathology.</p><p>As a new clinical nosology, normocalcemic PHPT was first officially recognized at the Third International Workshop on Management of Asymptomatic PHPT in 2008, but there have been yet no common recommendations for its treatment. Some studies have shown a response to medical therapy and improved indicators of bone mineral density after parathyroidectomy in these patients. According to the experts of the Fourth International Workshop in 2014, nPHPT remains one of the key topics for further research.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>первичный гиперпаратиреоз</kwd><kwd>нормокальциемический первичный гиперпаратиреоз</kwd><kwd>кальций крови</kwd><kwd>витамин D</kwd><kwd>остеопороз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>: primary hyperparathyroidism</kwd><kwd>normocalcemic primary hyperparathyroidism</kwd><kwd>serum</kwd><kwd>calcium</kwd><kwd>vitamin D</kwd><kwd>osteoporosis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дедов И.И., Мокрышева Н.Г., Мирная С.С., и др.
