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...

Aim: IFNα is a key regulator of the initial dialogue between pancreatic β-cells and the immune system in type 1 diabetes (T1D). IFNα induces endoplasmic reticulum (ER) stress, insulitis and a massive HLA-ABC overexpression in human β-cells, three histological hallmarks of T1D. Against this background we investigated the global role of IFNα on iPSC-derived islet-like cells, used here to mimic islet cells in the early neonatal period when autoimmunity ag...

Background: Adrenocortical carcinoma (ACC) is a rare cancer associated with hereditary syndromes in 10% of cases. However, data on germline variants (GVs) in adult patients with sporadic ACC are limited.Methods: We analyzed germline DNA from 150 adult patients with sporadic ACC sequentially referred to our centers between 1998-2019. We designed a custom panel of 17 genes potentially involved in the pathogenesis of ACC: AIP, APC, ARMC5, ARNT, BRCA1, BRCA2...

Introduction: Continuous glucose monitoring systems (CGM) have revolutionized the monitoring of diabetes, allowing real-time measurement of interstitial glucose levels. Although these devices are suitable for patients on insulin therapy, they are not yet routinely used in an inpatient setting. The difficulty observed in the glycemic control of hospitalized patients under intensive insulin therapy led to the development of a protocol to study the application of CGM in these pat...

Introduction: In 2020, a group of experts proposed to change the term “non-alcoholic fatty liver disease” (NAFLD) to “metabolic-associated fatty liver disease” (MAFLD), which includes hepatic steatosis (HS) (using imaging or analytical scores) associated with overweight or obesity, type 2 diabetes (T2D), or the presence of two other metabolic disorders.Objectives: Analyse the impact of bariatric surgery on MAFLD.<p class="abstext"...

The mutations of succinate dehydrogenase subunits (SDHA, SDHB, SDHC, SDHD) are linked with a predisposition to develop pheochromocytoma and paraganglioma, often in diferent locations of the body. With greater acces to genetic tests, current estimations suggest that 40-50% of pheocromocytoma and paraganglioma cases are inherited and half of them are due to SDH mutations. These mutations can be associated with other tumours like renal carcinomas, gastrointestinal stroma tumours ...

Introduction: Alemtuzumab is an humanized monoclonal antibody used for treatment of Relapsing remitting Multiple Sclerosis (RRMS). One of its main adverse effects is thyroid dysfunction, being a fluctuating hypothyroidism the most frequent presentation. Sometimes this thyroid disturbance is so significant that it might lead to alemtuzumab withdrawal. We present two Clinical cases of hyperthyroidism secondary to alemtuzumab with different clinical courses. <p class="abstext...

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±...
