Primary hyperparathyroidism (PHPT) is the third most frequent endocrine disorder and has a variable clinical presentation. Asymptomatic PHPT became the predominant form of the disease with increase of its incidence after the introduction of automated serum calcium measurement in North America and Europe. Data from Russia is lacking. Aim: To present the clinical profile of PHPT in Russia. Materials and Methods: This retrospective study was conducted at endocrinology centers in 8 regions of Russia. We analyzed the clinical presentation, and treatment options in patients with confirmed PHPT (1995-2010). Results: 738 patients (F: M-8:1) with age ranging from 13 to 83,4 years (mean 54,3) were analyzed. 54% was from Moscow (n=397), 11% - from Moscow region (n=79) and 35% - from 53 regions of Russia (n=262). Symptomatic PHPT was the most common form (74%) and was revealed with osteoporosis in 56%, nephrolithiasis - in 45% and ulcer disease - in 18%. Our data showed an increase in the incidence of PHPT (especially mild PHPT) after 2005 compared with earlier period. 64,9% of patients were treated surgically, 17 patients undergone repeated parathyroid surgery. 28,3% received bisphosphonates, calcitonin and/or cinacalcet . 11,5% was observed without treatment. Conclusions: This data analyzes some causes of delayed diagnosis of PHPT in Russia, characterized age and gender distribution of patients with PHPT and demonstrates the changes in clinical profile of disease from 1995 to 2010. PHPT still remains symptomatic disorder in our country most frequently with skeletal and renal manifestations.

Приведены 2 клинических случая поздней диагностики тяжелых форм первичного гиперпаратиреоза. повлекшие за собой неоправданные врачебные манипуляции, и развитие тяжелых осложнений заболевания. В первом случае из-за ошибочного диагноза остео... и нерасп ПГПТ пациентки подверглись многократным операциям на нижней челюсти. Во втором случае поздний диагноз ПГПТ у молодого пациента, несмотря на успешное хирургическое вмешательство привел к прогрессирующей ХПН и развитию вторичного гиперпаратиреоза.
