Introduction: Cortisol has important roles in the regulation of body composition and hypercortisolaemia have major impact on body fat distribution. The aim of this study was to analyze differences in adipose tissue distribution in women with Cushing’s disease and Cushing’s syndrome due to adrenal adenoma.Method: We evaluated 12 women with Cushing’s syndrome, six with ACTH secreting pituitary adenomas (Group A) and six with adrenal adenomas...

Introduction: Luteinizning hormone (LH/hCG) responsiveness has been documented in both normal and pathological adrenal glands, but it is unclear whether chronic exposure to LH could affect adrenal function by increasing LH receptor (LHR) expression.Subjects and methods: We studied 12 postmenopausal women with previously documented adrenal tumor. All patients underwent standard hormonal testing for assessment of tumor functionality. Then hCG test was perf...

Adrenocortical carcinoma (ACC) is rare malignancy associated with poor prognosis. The aim of this study was to present clinical characteristics and survival of patients with ACC and to analyse the effect of prognostic factors on survival.We retrospectively analysed 69 patients (46 female and 23 males) with pathologically confirmed ACC who were treated in our hospital between January 2005 and December 2015. The median age at diagnosis was 51,0 years (rang...

Introduction: Klinefelter syndrome patients (KS) frequently show low bone mass, which could have multiple aetiologies. The structural basis of low bone mass and its consequences on bone strength are almost not known, but analogies in bone microstructure and strength between KS and ageing women have proposed by studying distal tibia by HRpQCT. The aim of this study was to compare proximal femur strength and bone structure of KS with elderly women and men....

PTH promotes conversion of 25-hydroxyvitamin D (25[OH]D) to 1,25-dihydroxyvitamin D (1,25[OH]2D), thus stimulating intestinal calcium and phosphate absorption. Because of low PTH levels in hypoparathyroidism, patients are prescribed calcitriol. Patients are predisposed to hyperphosphatemia owing to loss of PTH-stimulated phosphate excretion by the kidneys. Effects of rhPTH(1–84) on vitamin D metabolism and serum phosphate were studied.In ...

Introduction: Chromogranin A (CgA) is a major representative of the protein family named granins stored predominately in secretory granules of the diffuse neuroendocrine system. Circulating CgA serves as a biomarker of neuroendocrine tumors (NETs), but its increased plasma concentration is present in various cardiovascular, gastrointestinal, renal and inflammatory diseases. Intra-granular and/or extracellular proteolysis of CgA generates a variety of biologically active fragme...

Background: In severe obesity, hypogonadism in men and androgen excess in women are frequently observed. Sex hormones play an important role in body composition, glucose and lipid metabolism. Bariatric surgery is the most effective treatment strategy to combat morbid obesity. However, if preoperative gonadal dysfunction impacts weight loss and metabolic improvements after surgery is not known.Methods: 49 men and 104 women were included in a retrospective...

Background: Patients being cured of craniopharyngioma (CP) often suffer from severe hypothalamic obesity due to tumor localization or therapeutic interventions, which has a major impact on increased mortality and reduced quality of life. Gastric bypass surgery (GBS) was suggested to be an effective therapeutic option for weight reduction in those patients. However, long-term changes in body weight and postsurgical complications are unknown.Methods: 5 pat...

The aim of this research was foot mineralization level definition by means of the two-absorbing X-ray densitometer and marking out group of the greater risk of a foot mineralization disorder development at patients with diabetes.Materials and methods: Decrease in a foot mineralization at diabetes patients conformed a mineralization of metatarsal bones below 0.50 g/cm2 level and (or) tarsal bones below 0.69 g/cm2 level.<p class="...

Cushing’s disease is relatively rare and affects most commonly adults aged 20 to 40. It is associated with high morbidity and mortality; early detection and diagnosis of Cushing’s disease may lead to decreased this two facts and improved quality of life.We present a 32-year-old man with abdominal purple striae, central obesity with typical ‘moon face’ and oscillatory blood pressure values.Hormonal exams revealed...
