Introduction: A key feature of a benign adrenal tumor is its hormonal production. It is reflected by serum steroid levels. A tumoral tissue steroid content is not commonly measured.Methods: A steroid metabolome comprising of 65 steroids was measured in four samples from each of two patients using GC-MS in serum before and after 1mg dexamethasone test, in the tumoral tissue and in the adrenal tissue of two female patients with adrenal adenomas. The first ...

Introduction: Cushing’s syndrome (CS) is a rare disease with incidence estimated 2-4 cases per million inhabitants per year. ACTH-dependent forms comprise up to 80% of all cases, of which 80% are central and 20% are ectopic, paraneoplastic forms of ACTH-dependent CS. Thymic neuroendocrine tumors (NET) are accounting for 0,4 - 3% of all NET’s with incidence of 0.02/100 000 inhabitants/year. Up to one third of them are hormonally active (secrete adrenocorticotropic hor...

Objective: Fibroblast growth factor 19 (FGF-19) and FGF-21 are novel metabolic regulators that improve insulin resistence and obesity in rodents. The objective of this study was to explore whether changes in serum concentrations of FGF-19 and FGF-21 contribute to positive metabolic effects of weight loss induced by surgical treatment of obesity – sleeve gastrectomy (SG).Methods: Serum concentrations of FGF-19 and 21, adiponectin, resistin, fatty aci...
