Introduction: Prolonged exposure to stress has a modifying effect on activity of hypothalamo-pituitary-adrenal (HPA) axis. This is a protective adaptation aimed to diminish potential deleterious effects of chronic hypercortisolism, and to diminish effects of acute exposure to heterotypic forms of stress. Our aim was to analyze modes of cortisol response to acute physical stress in groups of different stress categories and sex.Subjects and methods: Study ...

A 36-years-old male with mild hypertension was diagnosed with pseudocystic tumor (67 mm) in pancreatic region and liver metastasis in April 2010. One month later, the extirpation of retroperitoneal mass and metastasis was performed in local medical centre. Pathohistological diagnosis was metastatic paraganglioma (Ki67, 3.5%). In June 2010, he was transferred to our Institution, and (131) I-metaiodobenzylguanidine (MIBG) scintigraphy was negative. However ((18) F) fluorodeoxygl...

Introduction: Most patients with neuroendocrine tumors (NETs) present with liver involvement at the time of diagnosis. Trans-catheter arterial chemoembolization (TACE) is accepted treatment of patients with non-resectable hepatic metastases from NETs.Aim: To analyze objective tumor response and clinical outcome in patients with hepatic metastases from NETs who underwent TACE.Methods: Thirty-one patients underwent 140 TACE procedure...

Introduction: The coexistence of adrenal tumors (AT) in patients with neuroendocrine tumors (NETs) has not been extensively studied. The aim of our study was to investigate their prevalence and clinical significance in these patients.Materials and methods: We retrospectively studied 447 patients with NETs of all localizations, treated at our department between 2004 and 2012. Diagnosis was established pathohistologically, classification performed accordin...

Introduction: It has been shown that most women with polycystic ovary syndrome (PCOS) have increased adrenal androgen production, enhanced peripheral metabolism of cortisol and elevated in urinary excretion of its metabolites. Simultaneously, this increased cortisol clearance in PCOS was shown to be followed by a compensatory overdrive of the hypothalamo–pituitary–adrenal (HPA) axis. The aim of this study was to determine HPA axis sensitivity in women woth PCOS.<...

Introduction: Women with polycystic ovary syndrome (PCOS) are characterized with insulin resistance and hyperinsulinaemia. Adiponectin and leptin are adipose tissue-specific products and are correlated with insulin resistance. The aim of the study was to access the relation of adiponectin with anthropometric, metabolic and hormonal parameters in a group of women with PCOS.Methods: We studied 57 non-obese women with PCOS diagnosed using ESHRE/ASRM criteri...

Introduction: Generously supported by IPSEN)-->The coexistence of acromegaly and secondary polycythemia has been described in a few patients. This association was ascribed to GH/IGF1 proliferative effect on bone marrow progenitor cells. In contrast, the presence of myeloproliferative neoplasm (MPN) with documented JAK2 mutation so far has been described in only one acromegalic patient.Methods: We analyzed the p...

Introduction: Intronic BclI polymorphism of glucocorticoid receptor (GR) gene and adrenal adenomas of incidental discovery are frequently associated with metabolic syndrome. We studied in these patients metabolic and hormonal parameters, the sequence alteration in BclI polymorphism of the GR gene from constitutive DNA and the expression of Hsp70 within the tumor and in tissue adjacently to tumor.Patients and methods: We assessed 114 healthy...

Background: Several susceptibility genes have been found to be associated with development of pheochromocytoma (PHEO): RET, VHL, SDHB and SDHD. We investigate the frequency of germ-line mutations in SDHB and VHL genes in patients with apparently sporadic PHEO.Material and methods: Fifty patients (38 women, mean age 42) with apparently sporadic adrenal and extra-adrenal PHEO were screened. DNA was extracted from whole blood and from paraffin embedded tumo...

A 34-year-old woman was initially presented with clinical signs of Cushing’s syndrome (CS). On endocrinological examination, a diagnosis of ACTH dependent CS was established (serum cortisol: 08.00 h: 1245 nmol/l; 24.00 h: 275; plasma ACTH concentration 104 ng/l; inadequate cortisol suppresion on LDDST (787) and suppresion to 318 following HDDST). A magnetic resonance imaging (MRI) confirmed a microadenoma in the left part of the pituitary. Ultrasound examination confirmed...
