Serum 25-hydroxy-vitamin D (25OHD) is considered the most reliable marker of vitamin D status. Adequate levels 25OHD of are necessary for pleiotropic effects of vitamin D, either skeletal or extra-skeletal. Traditional assays based on immunoassay often show an unsatisfactory accuracy and sensibility. A valuable alternative is Tandem Mass Spectrometry coupled to High Performances Liquid Chromatography (HPLC-MS-MS), that offers a good quantification accuracy, as the contribution...

Introduction: Clinical and laboratory hyperandrogenisms indistinctly contribute to PCOS diagnosis; however, they differ in hormonal and metabolic correlates and require proper therapeutic strategies. Circulating biomarkers of hirsutism were not identified so far, with elevated testosterone being observed only in half of hirsute patients. Reasons for such inconsistencies possibly relies in previously used immunoassays, nowadays recognized as not adequate because of poor reliabi...

Background: Cell membrane fluidity of erythrocytes in patients with type 2 diabetes can be influenced by glycosylation processes, changes in lipid homeostasis and oxidative stress.Objectives: We have measured red blood cell membrane fluidity looking for differences between healthy people and diabetic subjects and also between diabetic patients affected by macroangiopathy (vascular diabetic foot) and not.Methods: We have enrolled 32...

Introduction: Historically, treatment of follicular thyroid carcinoma (FTC) and oncocytic thyroid carcinoma (OTC) is based on thyroidectomy followed by radioiodine (RAI) therapy. Both tumor types have a good prognosis (10-year survival 80-94%), but this changes significantly once RAI-refractory disease occurs (median 3.5 years), which limits further treatment possibilities. The main risk factors for developing RAI-refractory disease in FTC and OTC are unknown. Our aim was to i...

Background: The association of autoimmune thyroiditis (AIT) with nonendocrine autoimmune disorders has been reputed for long time as a variant of type 2 polyglandular autoimmune syndrome (PAS2). Nowadays, it is framed in the picture of polyautoimmunity and its relevance is owed to its prevalence, far higher than PAS 2, and its expanding galaxy. Systematic studies on this field are rather scanty and mostly based only on the presence of circulating antibodies. Our study has been...

Purpose : To assess the utility of (18F)fluoroethyl-L-tyrosine PET co-registered with magnetic resonance imaging (FET-PET/MRICR) in patients with difficult-to-localize prolactinoma to inform clinical decision making and treatment planning.Methods: Retrospective cohort study of 17 consecutive patients with difficult-to-localize prolactinoma undergoing FET-PET/MRICR between October 2020 and Amgust 2022 for either (1) additional inform...

Background: The clinical burden of Klinefelter Syndrome (KS) is not limited to the impairment of gonadal function and an increased prevalence of cardio-metabolic, endocrinological and oncological diseases, but also involve several cognitional, behavioural and psychological issues. Because of the wide heterogeneity in clinical phenotype, the diagnosis of KS is still challenging, resulting in a significant number of patients to remain undiagnosed or to have a late diagnosis. Ver...

Introduction: Lipodystrophy is a rare disease that can present with a broad range of symptoms. Delays in diagnosis are common, which in turn, may predispose to the development of severe metabolic complications and end-organ damage. Many patients with lipodystrophy are only diagnosed after significant metabolic abnormalities arise.Aim: Prompt action by clinical teams may improve disease outcomes in lipodystrophy. The aim of the Rapid Action Plan is to ser...

Background: Obesity represents a threatening worldwide epidemic but, beyond the guidelines recommendations, its modalities of treatment in the medical community appear as variable and not clearly defined. Aim of our survey was to assess the present real-world approach to obesity management in Italy.Methods: Online anonymous survey among the 2248 members of the Italian Association of Clinical Endocrinologists (AME). The survey included 8 questions about d...

Introduction: A possible association between the severe acute respiratory syndrome coronavirus (SARS-CoV)-2 pandemic, in terms of infection and/or vaccination, and subacute thyroiditis (SAT) has been recently reported. Although a higher SAT incidence in pandemic has been described, data are still conflicting.Aim: To determine SAT incidence in Italy during the SARS-CoV-2 pandemic and to characterize clinical peculiarities and response to medical treatment...
