Introduction: Chronic exposure to glucocorticoid excess, either endogenous or exogenous, is associated with a hypercoagulable state and a high thromboembolism risk. The underlying mechanism of this phenomenon is still unclear. Clinical studies have indicated various abnormalities of procoagulant, anti-coagulant and fibrynolytic factors, e.g.: alterations of clotting factors (F), plasminogen activator inhibitor (PAI-1), plasminogen, antithrombin. Moreover, other consequences of...

Papillary thyroid cancer (PTC) is well known family occurring cancer disease. It is estimated, that ~5% of differentiated thyroid cancers (where PTC is the most frequent) are hereditary. Susceptibility genes are poorly known, however, recently some SNPs located on chromosome 9 in FOXE1 locus (rs965513) and on chromosome 14 (rs944289) close to NKX2-1 locus have been confirmed to be associated with PTC in different populations.The aim of our study was to a...

Objectives: Recent studies on BRAFV600E mutation, known as initiating event in papillary thyroid carcinoma (PTC) and related to more aggressive clinical course of the disease, revealed its significant influence on gene expression profile suggesting that BRAF(+)PTCs represent a molecular subtype of PTC. However, the human material disables distinction of possible molecular causes of cancer from its effects, unlike the mouse model. The main goal of our project was to find genes ...

Background: Several evidences suggested that conventional glucocorticoids (CGCs) used as replacement treatment in adrenal insufficiency (AI) are inadequate to mimic physiological cortisol circadian rhythm (CCR), and that CCR disruption, represented by non-physiological pattern of peaks and troughs and elevated evening GC levels, might be responsible for the increased metabolic and, consequently, cardiovascular risk. It has been demonstrated that once daily dual-release-hydroco...

Obesity is caused by an imbalance between dietary energy intake and expenditure. The expression of dopamine receptors (DRs) in human adipocytes has been already demonstrated. Moreover, the effects of cabergoline, a dopamine agonist, on body weight and glucose homeostasis in obese subjects without hyperprolactinemia has already been reported. The current study investigates the effects of cabergoline on lipid accumulation and on adipogenic factors expression to better define the...

Introduction: Incidence of type 1 diabetes mellitus (T1DM) is rising steadily around the globe, including Armenia. It is one of the most common autoimmune and metabolic disorders in pediatric population, resulting from autoimmune destruction of pancreatic β-cells leading to insulin deficiency. Gut microbiota (GM) is reportedly involved in the pathogenesis of T1DM likely by influencing the immune response with the help of arginine-metabolizing enzymes. Arginase i...

Introduction: Endocrine disorders and kidney diseases can coexist. Some of these have a common pathophysiological background. Strategies for treating endocrinopathy or glomerulonephritis (GN) may affect the function of the endocrine system and kidney.Aim: The study was aimed to assess the correlation of kidney biopsy results performed in people with suspected GN with thyroid function, metabolic syndrome and diabetes occurrence.Mate...

The Barraquer-Simons syndrome is a rare form of partial symmetric lipodystrophy with involvement of the face and upper body, of unknown cause, characterized by loss of subcutaneous fat in the face and started stretching for the upper body.Case report: Female patient, 26 years old, presenting morphologic change in facies, chest, upper limbs, lower limbs and abdomen since she was 10 years old. Last year, she has increased weight at 30%, with apparent muscl...

Introduction: Anophthalmia/microphthalmia is a rare developmental craniofacial defect often associated to congenital hypopituitarism with GH deficiency and hypogonadism. SOX2 gene plays a key role in embryonic development regulation and heterozygous mutations of this gene, reported only in 14 patients to date, have been associated to anophthalmia/microphthalmia and congenital hypopituitarism in uo to 10% of cases. Therefore, the study of the SOX2 gene can be clinically useful ...

Introduction: Hyperprolactinemia is reportedly associated with an impaired metabolic profile, particularly in patients with concomitant hypogonadism. The current study aimed at investigating the effects of short (12 months) and long (60 months) treatment with cabergoline (CAB) on metabolic complications, metabolic syndrome (MS) prevalence and visceral adiposity index (VAI) in hyperprolactinemic patients.Patients and methods: Seventy-one patients (51 F, 2...
