Background: Secondary hyperparathyroidism (SHPT) is severe complication of chronic kidney disease, characterized by high serum parathyroid hormone (PTH), parathyroid gland hyperplasia, and disturbances in mineral metabolism. Effective management of SHPT includes measures to prevent hyperphosphataemia and excess PTH, to maintain serum calcium within the normal range. In dialysis patients with severe SHPT, medical treatment may fail and parathyroidectomy (PTX) is indicated for d...

Objective: Primary hyperparathyroidism (PHPT) is associated with increased cardiovascular morbidity including hypertension with a prevalence ranging from 40 to 65%. The renin-angiotensin-aldosterone system (RAAS) is a key system in the regulation of sodium/potassium balance, volume homeostasis as well as blood pressure. There is increasing evidence of interactions between calcium and calcium-regulatory hormones with the RAAS. The aim of this study was to investigate the associ...

Background: DiGeorge syndrome (DGS) is the rare genetic disorder caused by a 22q11.2 chromosome microdeletion. The main clinical features are associated with defective development of the pharyngeal pouch system and usually include congenital heart disease, hypoplasia of thymus resulting in immune deficiency and hypoparathyroidism. Also DGS patient has characteristic long face with narrow palpebral fissures, broad nasal bridge, micrognathia and small mouth, small dysmorphic ear...

Introduction: Normocalcemic primary hyperparathyroidism (NPHPT) is defined as a condition in which persistently normal serum calcium levels are observed in the presence of high levels of parathyroid hormone (PTH). NPHPT is a new entity which possibly represents a clinically symptomatic disease and which has generated a considerable scientific interest.Aim: To compare the clinical and laboratory data between the normocalcemic and hypercalcemic forms of PH...

Introduction: Atypical parathyroid adenoma (APA) is rarely encountered cause of primary hyperparathyroidism (PHPT). No definite criteria are considered to distinguish preoperatively APA from parathyroid typical adenoma or carcinoma.The aimTo describe the clinical course of a patient with an atypical parathyroid adenoma with severe hypercalcemia and multiple fragility fractures.Case presentation: A 61-year-old...

Background: In most cases of parathyroid carcinoma (PC) only recurrence could be a credible feature of malignancy.Clinical case: At the age of 19 years a woman was diagnosed with urolithiasis. At the age of 22 years she had a surgical resection of the neck nodule at the right site in the projection of carotid triangle. After the histological study, ectopic parathyroid tumor was misdiagnosis with paraganglioma (material is available for review). At the ag...

Background: Mineral and bone disorders in chronic kidney disease (CKD-MBD) is a systemic disorder of mineral metabolism due to CKD, which is manifestedby abnormalities of calcium, phosphorus, parathormone (PTH) and vitamin D; renal osteodystrophy; extraskeletal calcification. In patients with CKD, vascular calcification occurs 10–20 years earlier than in the general population, and is highly prevalent (40–92%) in the hemodialysis population. «AngioScan-01&#187...

Objective: Primary hyperparathyroidism (PHPT) is one of the most frequently diagnosed endocrine disorders. The Russian Registry of PHPT is an on-line web-based database with the aim to estimate the prevalence and main features of disease. PHPT in Multiple Endocrine Neoplasia type 1 (MEN-1) is associated with polyglandular and early involvement of parathyroid glands.Material and Methods: The database from The Russian Registry of PHPT was used for retrospe...

Objective: Postsurgical hypoparathyroidism (HypoPT) is the most common etiology of disease and often occurs after thyroid surgery. However, the differential diagnosis between different forms of HypoPT in some cases remains a challenge. We present the clinical case of postsurgical and functional HypoPT combination.Case description: A 44-year-old female was referred to the Endocrinology Research Centre. She underwent total thyroidectomy for follicular aden...

Objective: Primary hyperparathyroidism (PHPT) is one of the most frequently diagnosed endocrine disorders. The Russian Registry of PHPT is an on-line web-based database created in 2016 with the aim to estimate the disease prevalence and improve the quality of health care for such patients in Russian Federation. The Endocrinology Research Centre, Moscow represents The Head organization.Material and methods: We retrieved retrospective data submitted to the...
