Background: Women with polycystic ovary syndrome (PCOS) appear at increased cardiovascular risk due in part to a dyslipidemia characterized by increased plasma triglyceride and reduced high density lipoprotein (HDL) cholesterol levels. Insulin resistance is one of the features of PCOS and potentially affect lipid metabolism.Objectives: The aim of this study was to compare basal insulin levels and lipid profile in lean women with PCOS with weight matched ...

Background: Women with polycystic ovary syndrome (PCOS) appear at increased cardiovascular risk due in part to a dyslipidemia characterized by increased plasma triglyceride and reduced high density lipoprotein (HDL) cholesterol levels. Obesity, insulin resistance and hyperandrogenemia are features of PCOS and potentially affect lipid metabolism. On the other hand, obesity has an important influence on the lipid metabolism.Objectives: The aim of this stud...

In supine subjects aldosterone daily variations are determined by spontaneous PRA rhythmicity and ACTH secretory bursts. The aim of this study was to analyze diurnal and pulsatile aldosterone secretion in two patients with primary aldosteronism (PA): a 33-year-old woman with aldosterone producing adenoma (APA) and a 40-year-old woman with idiopathic adrenal hyperplasia (IAH). Blood samples were taken hourly during 24 hours at the time of the diagnosis and three months later, a...

In this study we wanted to assess whether affective changes influence cortisol response during low dose (1 microgram) ACTH test. Beck Inventory of Depression and Hamilton Anxiety Rating Scale and low dose ACTH test were performed in five subjects during the prolonged psychological stress induced by war and 18 months later. After the war, Beck Inventory of Depression and Hamilton Anxiety Rating Scale scores were significantly reduced. Suppression of the HPA axis was present dur...

Background: Although it is well known that glucocorticosteroids induce insulin resistance, probably due to postreceptor defects, the exact time scale is still a matter of debate.Objective: The aim of the present study was to determine the time scale of effects of therapeutic doses of glucocorticoids on insulin sensitivity.Methods: Study group consisted of 20 patients with Graves ophtalmopathy who were treated with corticosteroids f...

It is supposed a simillar dirnal change of TSH, free fatty acids (FFA) and leptin in humans. Hypothalamic-pituitary-thyroid axis (HPT) is suppressed during food deprivation while there is an elevation of FFA further influencing glucose metabolism. The aim of our study was to investigate whether leptin can act as a metabolic signal linking the adipose tissue metabolism and the HPT. We studied 13 women with polycystic ovary disease-PCOS (mean age: 26.6±1.83 years; BMI: 34...

Background: Thyroid function regulates a wide array of metabolic parameters and significantly affects lipoprotein metabolism. Subclinical hypothyroidism (SCH) is the most common thyroid disorder, with a prevalence up to 10% in adult populations. Subclinical hypothyroidism is defined as mild elevation in thyroid stimulating hormones (TSH) in presence of normal free thyroxine (fT4) and free triiodothyronine (fT3). This mild elevation of serum TSH is caused by a minor initial dec...

Background: Ectopic Cushing’s syndrome (ECS) frequently represents a diagnostic challenge due to its complex clinical presentation.Case presentation: A 57-year-old male presented with typical Cushingoid appearance, high adrenocorticotropic hormone (ACTH) level (138.3 pg/ml), lack of cortisol circadian rhythm and suppression in overnight 1 mg dexamethasone suppression test (DST) (1374 nmol/l). Great daily fluctuation of serum cortisol levels from ver...

Graves’ disease (GD) is an autoimmune disease that can affect other tissues in addition to the thyroid gland. Depending on the intensity of the immune response, in addition to hyperthyroidism, orbitopathy, dermatopathy and acropachy can also occur. Extrathyroidal manifestations of GD are most often the result of a more pronounced immune response. Thyroid dermatopathy (TD) is a rare extrathyroidal manifestation of GD, almost always associated with Graves’ orbitopathy ...

Background: Thyroid hormones have regulatory effect on serotonin and noradrenaline and thyroid dysfunction is closely linked to some mental disorders. Besides depression and anxiety, and increased risk for suicide is demonstrated in patients with Graves’ disease (GD).The aim: of our research was to determine the symptomatology of depression in patients with hyperthyroidism and Graves’ orbitopathy (GO) and compare it with hyperthyroid patients w...
