Background: Ketoconazole is a synthetic antifungal drug, and powerful inhibitor of steroidogenesis. Oral ketoconazole blocks both ovarian and adrenal androgen biosynthesis, and glucocorticoid synthesis, leading to a reduction in circulating testosterone and cortisol levels. In subjects with an intact HPA axis, ketoconazole by decreasing cortisol levels leads to compensatory rise an ACTH level.Objectives: To assess influence ketoconasole induced changes i...

Aim: The aim of this study was to compare clinical symptoms and TSH receptor antibodies (TRAb) in Graves orbitopathy (GO) in hyperthyroid patients to those patients with primarily hypothyroid and euthyroid status.Methods: Study group consisted of 54 primarily hyperthyroid (39 female, 14 male, 47±9 years) and 8 primarily hypothyroid and euthyroid patients (5 female, 3 male, 46±14 years). Clinical symptoms and TRAb were assessed. Assessment of th...

Background/objectives: The aim of the study was to assess hypothalamic–pituitary–adrenal (HPA) axis in patients with chronic fatigue syndrome (CFS).Design and methods: Twenty-three consecutive patients who fulfilled centers for disease control (CDC) criteria for CFS and twenty healthy controls were included in the study. Low dose ACTH test (1mcg of synthetic adrenocorticotropic hormone Synacthen) and insulin tolerance test (ITT) were done and b...

Background/objectives: The aim of the study was to assess association between diabetes mellitus (DM) and arterial hypertension (AH) in patients with adrenal incidentaloma.Design and methods: One hundred and eleven consecutive patients with incidentally discovered adrenal tumours were included in the study. OGTT was done and 24 h urinary catecholamines were measured. Aldosterone and plasma renine activity (PRA) were determined, and 1 mg dexametasone test ...

Background: Polycystic ovary syndrome (PCOS) is a common endocrine-metabolic disease that occurs in about 10% of women in reproductive age. Today, PCOS is considered not only reproductive edocrinopathy but also a metabolic disorder associated with long-term health risks, including diabetes mellitus and cardiovascular disease.Objectives: The aim of this study was to evaluate the presense of early vascular demage in normal-weight women with polycystic ovar...

The aim of the study was to assess the influence of thyroid hormones on lipid profiles in primary hypothyroidism, in order to determine the most influential one for the clinical follow-up. Study group included 15 subjects (3 male, 12 female, age 46±13 years/mean±S.D.), and total and free T4, total and free T3 and TSH, total, HDL and LDL cholesterol, triglycerides, ApoA, ApoB and Lp(a) were determined. The diagnosis of primary hypothyroidism was based o...

Background: Hypothyroid Graves’ ophthalmopathy is a rare condition, present in about 3% of all cases. Since thyroid-stimulating antibodies could be detected in a majority of euthyroid and hypothyroid Graves’ patients, the most probable explanation for unincreased thyroid function is a reduction of tissue capability to response to stimulation.Case report: A 57-yr-old man visited the hospital with signs and symptoms typical of hypothyroidism. Sin...

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...
