Background: Papillary thyroid microcarcinoma (microPTC), defined as PTC measuring 10 mm or less in greatest diameter, is the most common type of thyroid cancer. MicroPTC generally has an indolent clinical course, with slow and exclusivelly intrathyroidal growth, without any significant impact on patient morbidity and mortality of patients. Sometimes, even microPTC can show lymph nodes (LNs) involvement, ranging from incidental histological findings to preoperative evidence of ...

Inactivating PTH/PTHrP signaling disorders (iPPSDs, historically named pseudohypoparathyroidism (PHP)) are a group of rare disorders associated with resistance to parathormone (PTH) and other hormones due to impaired hormonal signaling via G protein coupled receptors. Hypercalcitoninemia has been reported in these patients, however very few reports are available. The aim of this study was to further investigate the prevalence and characteristics of hypercalcitoninemia in both ...

Aim: The aim of this retrospective study was to assess the efficacy of different doses of rituximab (RTX) in patients with active moderate-severe Graves’ Orbitopathy (GO).Methods: Overall 40 patients, 5 M/35 F; mean age (± S.D.) 58±11 years were treated with RTX; 21 were smokers. The patients received the following treatment: 14 patients (group 1) a single 100 mg dose; 15 patients (group 2) a single 500 mg dose and 11 Patien...

Background and Aims: Graves’ disease (GD) and orbitopathy (GO) are characterised by the presence of pathological anti-thyrotropin receptor antibodies. In thyroid autoimmunity, especially GD and GO, a dysregulation of several T cell subpopulations has been proposed, especially T regulatory (Treg) and T helper 17 (Th17) cells, determining (auto)immunity inhibition and enhancement, respectively. T follicular cells (Tf) within germinal centres (GC: aggregates of lymphocytes w...

Background: BAFF is a Serum B cell stimulating factor shown elevated in Graves’ disease, compared to controls (Vannucchi 2012). BAFF and its receptor are expressed on lymphocytes infiltrating the thyroid in Graves’ disease as well as on thyrocytes themselves (Campi 2015).Aims: A single-blind randomized controlled trial (EudraCT 2015-002127-26) has been conducted to test the efficacy of the anti-BAFF monoclonal antibody belimumab (BMB) in acti...

Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor of the parafollicular thyroid C cells. Although somatostatin (SS) receptors (SSTs) are expressed by MTCs, treatment with octreotide, specific for SST2, has shown poor efficacy in reducing MTC proliferation, whereas pasireotide, a multi-receptor SS analogue with preferential binding to SST5, has recently demonstrated antiproliferative effects in persistent postoperative MTCs. In vitro data in human MTC ce...

TNM 8th edition introduces changes in the staging of patients with differentiated thyroid carcinoma (DTC). This study aims at assessing the ability of TNM 8th edition in predicting structural recurrence of DTC.480 DTC patients were retrospectively evaluated by 7th and 8th editions of TNM staging systems in relationship with risk stratification, response to therapy and recurrence of disease as defined by 2015 American Thyroid Association (ATA) guidelines. As compared to the 7th...

A high risk for small bowel (SB) tumors in acromegalic population has been reported in a cohort study (Baris D, 2002). SB lesions may be easily investigated by the recently developed videocapsule endoscopy (VCE). Aim of the study was to assess the prevalence of SB neoplasms by VCE in 14 acromegalic patients (Ac) in respect to 30 sex and age-matched control subjects and to correlate it with cancer risk factors and acromegaly-related parameters. Local Ethical committee approved ...

Background: COVID-19 represents a global health emergency and infected patients with chronic diseases often present a severe impairment. Adrenal insufficiency (AI) is supposed to be associated with an increased risk of infections which could trigger adrenal crisis. Our primary aim was to evaluate the incidence of COVID-19 symptoms and complications in AI patients.Materials and methods: We conducted a retrospective case-control study, in 279 patients with...

Introduction: The need of a long-term follow-up in adrenal incidentalomas (AI) is debated and data on cardiovascular events (CVE) are lacking.Methods: In this retrospective study all patients referred to seven Italian Endocrine Centers for AI, without signs of hypercortisolism at baseline and with a ≥5 years follow-up (80.7±30 months, range 60–286), were enrolled. From 171 patients (121 F) aged 59.5±10.2 years (range 25–79) the ...
