Introduction: Hypoparathyroidism is the only endocrine deficiency for which replacement therapy with the missing hormone is not part of the clinical practice. High quality evidence on the use of PTH 1-34 or PTH 1-84 in hypoparathyroidism is missing.Objective: We aim to evaluate the efficacy and safety of PTH 1-34 and PTH 1-84, and to compare the two treatments when possible.Methods: We searched databases up to March 2021 for random...

Introduction: GEP-NENs represent a heterogeneous group of neoplasms with increasing incidence in the last years. Pathogenesis and risk factors of sporadic GEP-NENs are not clear and still debated. The aim of this study is to evaluate the main risk factors for sporadic GEP-NENs in patients followed by the NETTARE Unit (NeuroEndocrine TAsk force of of ‘Sapienza’ University of Rome).Methods: We performed a case-control study including 32 consecuti...

Introduction: Glucose metabolism impairment is a common complication of acromegaly. Somatostatin analogs (SSAs) are used as both first and second line treatment. The effect of SSAs on glucose metabolism in acromegaly is still debated.Aim: To address the following questions: 1) do SSAs affect glucose metabolism? 2) does the effect correlate with disease control? 3) do different SSAs – Lanreotide (LAN) and octreotide LAR (OCT) – affect metabolism...

Background: Hypothalamic-pituitary function and adipose tissue are deeply interconnected. Obesity has been linked to morpho-functional changes in several endocrine glands (thyroid, adrenal, gonads). No study has quantified the appearance of the pituitary gland in obese subjects.Aim: To measure pituitary signal intensity, homogeneity and texture of the pituitary gland at magnetic resonance (MR) in obese subjects free of focal pituitary disease.<p clas...

Introduction: Immune tumor microenvironment plays a key role in tumors’ growth and metastatic spread, while its role in the heterogeneous field of neuroendocrine neoplasms (NENs) remains unclear. There is evidence that tumor progression in NENs is promoted by an immunosuppressed microenvironment created by a plethora of infiltrating immune cells. Changes in circulating leukocyte and peripheral blood mononuclear cell (PBMC) subpopulations can mirror the local alteration of...

Background: Patients with adrenal insufficiency (AI) require long-term glucocorticoid (GC) replacement therapy and generally show an increased prevalence of bone metabolism alterations. Only few data are available on bone safety of dual-release Hydrocortisone (DR-HC) therapy.Objective: To evaluate bone metabolism in both primary AI (PAI) and secondary AI (SAI) during long-term therapy with DR-HC.Methods: We studied patients with AI...

Context: Acromegaly is associated with several metabolic and cardio-respiratory comorbidities, with a relative increase in the last years of cancer mortality. Although the GH/ IGF-1 axis has long been supposed to play a role on immune modulation, immune function in acromegaly is poorly known.Objective: This observational, prospective, single site, pilot study (NCT05069324) aims to analyse peripheral blood mononuclear cells (PBMCs) subpopulations in acrom...

Introduction: The role of Angiopoietin (Ang)/Tie2 kinase pathway in neuroendocrine neoplasms (NENs) has recently received increasing attention, but its clinical role remains unclear. Tie2-receptor inactivation favours chronic inflammation. The balance between its agonist and antagonist regulates its signalling. Aim of this study was to measure serum soluble Tie2 (sTie2) and Ang-2 in patients followed at the NETTARE Unit (NeuroEndocrine TAsk foRcE of ‘Sapienza’ Univer...

Introduction: Glucose metabolism impairment is a common complication of acromegaly. Pegvisomant (PEG) is used as second-line medical treatment in acromegaly. Data from literature suggest a positive effect of PEG on glucose metabolism but a meta-analysis has never been performed.Aim: To address the following questions: i) does PEG affect glucose metabolism? ii) does the effect correlate with disease control?Methods: We performed a m...

Introduction: Even if obesity has been associated to several hormonal imbalances, pituitary appearance at Magnetic Resonance Imaging (MRI) in obese patients is understudied.Aim: To measure pituitary signal intensity and homogeneity at MRI in obese subjects free of focal pituitary disease, in the context of the CHIasM study (Changes in the Hypotalamic-pItuitary region of patients with Metabolic syndrome and obesity).Materials and me...
