Neuroendocrine tumours (NETs) have a unique ability to produce and secrete a variety of biogen amines and peptide hormones. They arise from multipotential stem cells, which differentiate during tumorigenesis into specific cell lines. Some of these tumours are functional, producing characteristic clinical syndromes. We present a female patient incidentally discovered to have diffuse liver metastases of neuroendocrine tumour of unknown primary origin. She was free of symptoms at...

Introduction: Cognitive functions and mood (anxiety and depression) are often impaired in diabetes mellitus (DM). Dipeptidyl peptidase-4 inhibitor (DPP-4) has been shown to exert beneficial effects on insulin sensitivity and glycoregulation in T2DM patients. Introducing DPP-4 therapy leads to maintaining control of glucose levels which could ameliorate or slow down further cognitive and mood disorders impairment.Aim: To evaluate influence of selective DP...

Background: Hypopituitarism is characterised by multiple pituitary hormone deficiencies causing adverse metabolic milleu and body composition changes. Aim: Our aim was to investigate the gender related differences in the prevalence of metabolic syndrome (MetS) and metabolic profiles in patients with hypopituitarism compared to obese controls. Patients and methods: A retrospective study of 282 patients with hypopituitarism (136 wome...

Introduction: The most common etiology of endogenous Cushing’s syndrome (CS) is Cushing’s disease (CD). Patients with CS also represent a model of patients with metabolic syndrome (MetS) with associated increased cardiovascular morbidity and mortality. Insulin resistance and obesity, two major characteristics of CS, lead to the accumulation of triglycerides within hepatocytes and formation of fatty liver in these patients.Aim: To evaluate the p...

Introduction: Xanthomatous hypophysitis (XH) is characterized by inflammatory infiltration of the pituitary gland in which lipid laden macrophages predominate. It can be primary (3% of all primary hypophysitis) and secondary arising in the setting of other lesions: craniopharyngioma, Rathke’s cleft cyst (RCC), adenomas (with subclinical apoplexy). It is more common in women and younger people. The clinical presentation is similar to pituitary tumors and may prese...

Introduction: Structural and functional damage of the skeletal system resulting in fractures is a common complication of CD. Due to major effect of glucocorticoids on the trabecular bone, vertebral fractures are a common and severe complication which can lead to disability.Goal: To investigate the prevalence of skeletal complications (osteoporosis, osteopenia, presence of fragility fractures) in patients with Cushing’s disease, as well as gain insig...

Objective: Ionized calcium via calcium sensing receptors (CaSR) mediates feedback inhibition of parat hormone (PTH) secretion. The aim of this study is to evaluate the difference in PTH response during calcium infusion test (CIT), between patients with primary hyperparathyroidism (PHPT) and healthy control (HC).Methods: Study consisted of 15 patients with confirmed PHPT and parathyroid adenoma (57.20±11.38yrs) and 15 healthy subjects-HC (57.20±...

Background and aim: Aryl hydrocarbon receptor-interacting protein (AIP) is evolutionary conserved and widely distributed throughout organism. Broad interest for AIP comes from involvement of loss-of-function AIP mutations in pituitary adenoma pathogenesis. The role of AIP in normal pituitary function is largely unknown. AIP is co-localized with GH in somatotroph secretory vesicles. Serum AIP protein was proteomically identified. We aimed at investigating whether AIP and GH are...

Introduction: Selenium (Se) is a trace element that plays key roles in thyroid pathology. In patients with Hashimoto thyroiditis (HT), Se supplementation might reduce antibody levels and may provide additional beneficial effects, such as on cognition.Aim: To evaluate cognitive function (cognitive decline) in patients on long-term levothyroxine replacement for primary hypothyroidism with and without selenium supplementation.Design: ...

To investigate the prevalence of SH and osteoporosis in female patients with unilateral AIs (UAIs) and bilateral AIs (BAIs).We enrolled 106 female patients, 68 (64.2%) with UAIs and 47 (35.8%) with BAIs. SH was diagnosed in the presence of serum cortisol levels after 2-day low-dose dexamethasone suppression test (LDDST) >50 nmol/l with at least one of the following parameter (midnight serum cortisol >208 nmol/L, 24-h urinary free cortisol >24...
