Introduction: Hypogonadotropic hypogonadism is frequently observed in morbidly obese men, due to aromatase-dependent conversion of androgens to estrogens. The clinical impact of this sex hormone imbalance is unknown.Aim: Evaluate the clinical effects of aromatase inhibition in obesity-related hypogonadism.Methods: Double-blind, placebo-controlled, 6-month trial in severely obese men (BMI>35 kg/m2) with obesity-relate...

Autoimmune Thyroid Disease (ATD) is associated with normal thyroid function (type 1) in most cases with variable incidence of functional evolution toward either hypo (type2, A or B if present or not goiter) or hyperthyroidism (type3).To study the evolution of thyroid function in a longitudinal study, along a scale of six years, in relationship to thyroid volume, 128 subjects (80 females and 48 males), aged from 28 to 78 years, were considered, with the f...

Introduction: Hypogonadotropic hypogonadism is frequently observed in morbidly obese men, due to aromatase-dependent conversion of androgens to estrogens in adipocytes. The clinical impact of this sex hormone imbalance is not known.Aim: To evaluate the clinical effects of aromatase inhibition in obesity-related hypogonadotropic hypogonadism.Methods: Double-blind, placebo-controlled trial for 6 months in severely obese men (BMI &#62...

Context: In men, a decline of mean circulating testosterone level is seen with increasing age. This decline is associated with an increase in the mean levels of LH and FSH, albeit insufficient to maintain testosterone at its original level. It has been speculated that a higher sensitivity of the hypothalamus and/or pituitary for the feedback effect of circulating testosterone in older men is responsible.Objective: To compare the effect of experimentally ...

Atrial fibrillation (AF) and, in general, cardiac arrhythmias are among the most frequent complications during clinical thyrotoxicosis. However to-day the most frequent conditions of hyperthyroidism are subclinical and more subtle is the relationship between this last condition and cardiac arrhythmias.In order to evaluate this topic, we considered two groups: A) patients admitted into the hospital for AF; B) patients affected by subclinical hyperthyroidi...

Background: Concerns about the effects of gender affirming hormonal treatment (HT) on bone mineral density (BMD) exists, particularly for transmen with decreasing estrogen levels. HT in transpersons affects BMD on short term, but long-term follow-up studies are lacking. Therefore this study aimed to investigate the change in BMD during the first 10 years of HT in adult transwomen and transmen, in order to determine whether it is necessary to assess BMD during HT.<p class="...

Background and aimsLow levels of testosterone and non-alcoholic fatty liver disease (NAFLD) in obese men are both linked to the metabolic syndrome, but the independent association between testosterone and NAFLD needs to be elucidated. In this cross-sectional analysis the association between total testosterone (total T) and calculated free testosterone (cFT) on the one hand and NAFLD, non-alcoholic steatohepatitis (NASH) and fibrosis on the other hand was...

Background: Immune checkpoint inhibitors (ICI) targeting cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), programmed cell death protein 1 and its ligand (PD-1/PD-L1) are the current standard-of-care for many advanced cancers (1). This novel therapeutic approach comes with its costs in the form of immune-related adverse events (irAE). The underlying mechanisms are not yet fully understood. We explore the role of HLA in endocrinopathy related to ICI therapy using an interes...

Tirzepatide, a once-weekly dual co-agonist of Glucose-Dependent Insulinotropic Polypeptide (GIP) and Glucagon-Like Peptide 1 (GLP-1) receptors, has been demonstrated to improve glucose control and reduced body weight in different therapeutic approaches. With this rapid review and meta-analysis, we systematically reviewed the efficacy and safety of injectable incretin-based therapy added to basal insulin compared to basal insulin plus background treatments titrated rigorously t...

Introduction: Environmental toxins, including those deriving from illegal and hazardous disposal of urban and chemical waste, are known to act as endocrine disruptors and to increase the risk of malignancy and cancer mortality. The present study aimed at investigating prevalence and characteristics of thyroid diseases in the area of Acerra, a town in the perimeter of the so called ‘Land of Fires’.Methods: The screening included subjects aged &#...
