Background: Metabolic syndrome may be the nonclassical feature of primary hyperparathyroidism (PHPT) because an increased incidence of various glucose and lipid disorders is often observed in patients with this disease. Earlier we showed PHPT patients had higher serum triglycerides and higher rate of insulin resistance compared to the control group. Dynamics of metabolic parameters after surgery is ambiguous.The aim: of this study was to compare metaboli...

Background: In some patients with primary hyperparathyroidism (PHPT), glomerular filtration rate (GFR) demonstrate decrease after parathyroidectomy (PTE). GFR may decrease immediately after surgery due to general anesthesia, but after a month not all patients restore kidney function; a decreased GFR is also observed after 1–2 years after surgery.Aim: To find the pre-surgical factors of GFR decrease after PTE.Methods: Patients ...

Objective: Normocalcemic primary hyperparathyroidism (PHPT) is a phenotype of PHPT characterized by normal serum calcium and persistently increased parathyroid hormone (PTH) after exclusion of secondary causes of PTH elevation.The aim: of this study was to investigate the capability of the short test with active metabolites of vitamin D for differential diagnosis between normocalcemic PHPT and secondary hyperparathyroidism (SHPT) for inpatient treatment....

Background: Patients with type 1 diabetes have a significantly higher risk of coronary events, as well as diseases of the cardiovascular system.Purpose of the study – to show the relationship between metabolic, structural, and functional parameters of the cardiovascular system in young patients with DM1.Methods: The study included 60 patients without CVD: 40 patients with DM1 and 20 patients without DM1, the groups were comparable in age, sex, AMT, ...

Introduction: Transnasal adenomectomy is the main treatment for various pituitary adenomas. The hypothalamic-pituitary region is the site of synthesis and secretion of several hormones that have a direct effect on sodium-water metabolism, which leads to its frequent violation with the development of central diabetes insipidus and severe transient hyponatremia, the latter of which is the second most important cause of rehospitalization in the postoperative period. Currently, th...

Introduction: An atypical manifestation of disease combined with inconsistent results of examination, long history of multiple past health care services without effect requires to consider factitious disorders.Case report: A 46 year-old woman was suffering from episodes of severe hypokalemia (K+ 1.9 - 3.4 mmol/l (ref. 3.5-5.1 mmol/l) and hypertensive crises up to 240/145 mm Hg for 4 years. She stated that there was no clear provoking factor for these epi...

Background: Primary hyperparathyroidism (PHPT) can present with not only classic complications like bone and kidney pathology but also with different metabolic disorders and cardiovascular diseases. The prevalence of diabetes mellitus type 2 (DM2) in patients with PHPT is higher than in general population but the mechanism of carbohydrate metabolism alteration in PHPT remains unclear.Aim: The aim of this study is to estimate parameters associated with im...

Introduction: Primary hyperparathyroidism (PHPT) is one of the most common endocrine disorders. No major epidemiological research has been previously conducted in the Russia. This served as the basis for the creation of the Russian online registry of PHPT with accessibility from various regions of the country.Aim: Aim of this study was to estimate the clinical profile, surgical and medical therapy of the patients with different forms of PHPT.<p class...

Introduction: Primary hyperparathyroidism (PHPT) is commonly the most early manifestation of multiple endocrine neoplasia syndrome type 1 (MEN1), but it can also occur in young patients without any inherited disorders. The aim of our study was to compare the clinical characteristics of PHPT in young patients with MEN1 syndrome and with sporadic disease.Patients and Methods: The study included 72 patients with MEN-1 associated PHPT and 168 patients with s...

Introduction: Chronic hypoparathyroidism is a rare disease, which usually treated with active forms of vitamin D and oral calcium. Supplementation with native vitamin D can be useful both for achieving "non-skeletal" effects of vitamin D and for a more stable serum calcium profile.Aim: The aim of this study was to estimate the daily serum calcium and 24-hour urine calcium levels in patients with chronic hypoparathyroidism depending on different 2...
