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...

BackgroundThere are no specific markers for parathyroid carcinoma (PC) therefore, the development of algorithms for identifying high-risk patients is an urgent task.AimsTo determine clinical and laboratory predictors of PC and identify the factors of a poor prognosis.Materials and methodsA multi-center retrospective study included 242 patients with primary hyperpa...

BackgroundHypoparathyroidism is a rare disorder characterized by hypocalcemia and hyperphosphatemia due to absent or inadequate parathyroid hormone secretion. Data on effective treatment strategies and predictors of long-term complications have only recently began to emerge. The epidemiological information regarding chronic hypoparathyroidism in Russia is strictly limited that prompted this research.AimsTo es...

The combination of thyroid and parathyroid carcinoma (PC) are extremely rare. We present a case with metastases of both tumors to the lymph nodes of the neck in a woman who received renal replacement therapy with long-term hemodialysis.Case reportIn 1984, when she was 24 years old, the patient began working at a nuclear power plant as a chemical water treatment operator. The total length of service was 25 years. In 2009 (at the age...

IntroductionVitamin D deficiency is considered as a major public health concern. Due to vitamin D’s crucial role in the intestinal calcium absorption, its deficiency may result in hypocalcemia and in a spectrum of associated clinical manifestations.AimTo assess the effect of 25(OH) vitamin D level (25(OH)D) on the frequency of hypocalcemia episodes and the daily profile of serum calcium and 24-h urinary ...

Background: Primary hyperparathyroidism (PHPT) during pregnancy is rare and often unrecognized. Most of these patients are asymptomatic or have nonspecific complaints but some of them сan present with classical symptoms of PHPT and even with severe complications of pregnancy as preeclampsia, miscarriage, preterm labor etc. The incidence of maternal complications is approximately 67%, poor fetal outcomes, including stillbirth and intrauterine growth retardation may reach 80...

Background: The potential impact of SARS-CoV-2 on glucose metabolism has been discussed since the first days of the COVID-19 pandemic, and now has been confirmed by research results and clinical practice data about new-onset carbohydrate metabolism disorders after COVID-19. Determining the predictors of their development will help to determine the best treatment tactics.Aim: To determine predictors of carbohydrate metabolism disorders within 1 year after...

Introduction: Parathyroid carcinoma (PC) is one of the rarest endocrine malignancies. Most PCs are sporadic, sometimes occurring in the framework of familial primary hyperparathyroidism (PHPT). PHPT due to PC is usually characterized by significantly increased PTH levels, severe hypercalcemia, larger tumor size and a higher incidence of disease complications. Clinical case: A 56-year-old male C. presented with an accidental formation at the posterior con...
