The pathogenesis of insulin resistance is not completely understood, however, there are data that it might be associated with altered tissue carbohydrate and lipid oxidation. Adiponectin may be a key regulator of insulin sensitivity and energy metabolism. The aim of the present study was to determine the association of adiponectin, glucose metabolism (oxidation and storage) and lipid oxidation by applying the euglycemic clamp technique and indirect calorimetry.<p class="ab...

Introduction: Germline mutations of RET oncogene result in development of multiple endocrine neoplasia type 2 (MEN 2). There is a strong correlation between type of the RET sequence changes and the aggressiveness of main syndrome feature, medullary thyroid carcinoma (MTC), and the incidence of remaining manifestations, mainly pheochromocytoma (PHEO). For many of the RET germline mutations, the clinical risk have been precisely defined, but there are ...

Plasticisers such as bisphenol A (BPA), bisphenol S (BPS), and phthalates (PAE) are commonly used in daily life in electronic equipment, cans, plastic food containers, and bottles. These substances can interact with oestrogen receptors as well as androgen receptors and therefore they are called endocrine disrupting chemicals (EDC). The aim of this study was to evaluate serum concentrations of BPA, BPS, and selected PAE in healthy women and women with polycystic ovary syndrome ...

Introduction: Patients with connective tissue diseases are susceptible to the occurrence of side-effects of long term treatment with low-dose glucocorticoids as these medications often cannot be withdrawn due to exacerbation of the underlying disease. The new-onset of glucose metabolism impairment is not considered common in patients treated with low-dose glucocorticoids and the risk factors are thought to be the same as in general population: increasing age, obesity or family...

Objective: The diagnosis of Cushing’s syndrome may be challenging, especially in cases of patients with chronic kidney disease (CKD).Aim: The assessment of late night salivary cortisol concentration, serum and salivary concentration in overnight dexamethasone suppression test in patients with CKD stage III–V and a control group.Patients and methods: 37 patients mean age 66±12 (M=13) with CKD stage III–V...

Background: Irisin is an adipokine/myokine which could be connected with insulin sensitivity. Polycystic ovary syndrome (PCOS) is characterized by oligo- or anovulation, polycystic ovary, hyperandrogenism and insulin resistance.Objective: The aim of the present study was to determine the relationship between serum irisin concentration and insulin sensitivity (Mffm) as well as the effect of insulin infusion on circulating irisin levels in PCOS ...

Objective: Growth hormone (GH) is used for metabolic indications in the treatment of adult patients with GH deficiency (GHD). In addition to influencing growth processes in childhood, GH is important in regulating metabolic processes at every stage of life. GH, via insulin-like growth factor (IGF-1), has an anabolic effect on protein metabolism, also in skeletal muscles and cardiac muscle. Moreover, myokines produced by muscle fibers stimulated by muscle contraction, acting in...

Introduction: Ectopic Cushing’s syndrome (ECS) is a rare endocrine condition caused by corticotrophin (ACTH) hypersecretion of nonpituitary neoplasms. Thymic neuroendocrine tumours (NETs) account for about 5-10% of ECS cases, typically with aggressive clinical course.Case Report: A 31-year-old previously healthy female presented to the emergency department with a 3-week history of fatigue, muscle weakness, headaches and generalized swelling. Physica...

Isolated sarcoidosis of the hypothalamic-pituitary system is a very rare form of neurosarcoidosis. It usually leads to secondary damage to endocrine function, resulting in hypopituitarism and diabetes insipidus. A 32-year-old male patient with progressive deterioration of his general condition, weakness, polyuria, dizziness and visual field disturbances was admitted to the Department of Endocrinology for the diagnosis of a tumor in the hypothalamic-pituitary region. MRI showed...

: A 26 year old 22 weeks pregnant woman was referred to the Endocrine team after she presented with high blood pressure without evidence of proteinuria. She had no past medical history and was newly diagnosed with gestational diabetes. On clinical examination, she had some clinical features consistent with hypercortisolism such as very prominent large purplish striae over her abdomen, bad facial acne, multiple superficial ecchymoses due to easy skin bruisability and excessive ...
