Carney complex (CNC) is an autosomal dominant multiple neoplasia syndrome featuring cardiac, endocrine, cutaneous and neural tumours, as well as a variety of pigmented lesions of the skin and mucosa. Pituitary GH-secreting tumours are found in approximately 10% of patients with CNC. One of the genes responsible for CNC, the PRKAR1A gene, located on human chromosome 17q22-24, has recently been cloned. This represents a putative tumour suppressor gene, coding for the type 1alpha...

Introduction: Alteration in the expression of clock-related genes has been observed in various diseases. Adrenal sensitivity to adrenocorticotropic hormone (ACTH) apart from the hypothalamo-pituitary-adrenal axis is also regulated by the intrinsic adrenal clock. A link between clock genes and glucocorticoid adrenal production has been suggested by in vitro and animal studies. In the present study we investigated clock genes expression in human benign tumors of the adr...

Vitamin D (vit-D) deficiency is common in patients with gastro-entero-pancreatic neuroendocrine tumours (GEP-NET) and has been linked to reduced survival in these patients. Vit-D status was assessed in 183 patients with GEP-NET, at the time of their first presentation in the ARDEN-NET-Centre; and following simple advice at routine 6-monthly follow-up appointments to increase vit-D intake using over-the-counter vit-D preparations (Colecalciferol (Vit-D3), 1000–2000 units/d...

Introduction: Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disorders. Endocan is a novel molecule of endothelial dysfuction which is expressed in liver. SGLT2i have been reported to improve NAFLD through amelioration of inflammation. While there are contradictory results regarding the serum endocan levels in NAFLD patients, data regarding endocan expression in liver tissue are limited. Aim: Herein, we aimed to investigat...

Background: Sodium glucose co-transporter 2 inhibitors reduce the incidence of cardiovascular events in patients with type 2 diabetes mellitus based on the results of recent cardiovascular outcome studies. Herein, we investigated the effects of long-term treatment with empagliflozin on biochemical and immunohistochemical markers related to atherosclerosis development in apolipoprotein E knockout [Apo-E(−/−)] mice.Methods: At the ag...

Introduction: Somatostatin analogues (SSAs) are the mainstay of treatment for carcinoid syndrome (CS)-related symptoms. Controversy still exists regarding the extent of the efficacy of this intervention. The purpose of the systematic review and meta-analysis was to evaluate the percentage of patients achieving partial (PR) or complete response (CR) with the use of SSAs (lanreotide, octreotide, pasireotide) in patients with CS. Due to lack of uniformity and established criteria...

Introduction: Primary adrenal insufficiency (PAI) can be of autoimmune origin (AI), non-autoimmune origin (bilateral adrenalectomy, acute hemorrhage, infection) (NAI) or pharmaceutical (mitotane) origin. Studies have shown that these patients develop long-term morbidities and increased mortality due to excessive glucocorticoid tissue exposure. Data about differences concerning hydrocortisone (HC) needs, cortisol hormonal levels and metabolic parameters in these patients are sc...

Introduction: Neuroendocrine neoplasms (NENs) are neoplasms with a slow progression and a 5-year survival 77–95%. It is well known that secondary deposits of NENs may dedifferentiate during the natural history of the disease, presenting a more aggressive biological behaviour.Aim of the study: The prevalence of secondary foci dedifferentiation of pancreatic NENs (p-NENs).Methods: From the NENs database of 414 patients, 160 (38....

Sodium glucose co-transporter2 (SGLT2) inhibitors reduce the incidence of cardiovascular events in patients with Type 2 Diabetes Mellitus (T2DM) based on the results of recent cardiovascular outcome studies. Herein, we investigated the effects of long-term treatment with canagliflozin on biochemical and immunohistochemical markers related to atherosclerosis and atherosclerosis development in the aorta of Apolipoprotein E knockout (Apo-E(−/−)) mice. After...

The role of brown adipose tissue (BAT) in pathological states of energy homeostasis and impaired adipocyte function, such as obesity has been a major area of research interest in recent years. Herein, we sought to determine the direct effects of adipokines, visfatin and leptin on BAT thermogenesis. The effects of mouse recombinant visfatin, nicotinamide mononucleotide (NMN) and leptin with or without FK866 were studied on differentiated T37i cells. Treated cells were analyzed ...
