Background: Patients with CHH and KS have eunuchoid body proportions of the skeleton compared to normal male subjects, characterized by tall stature, and reduced upper-to-lower segment ratio (U/l). Vice versa, steroids exposure deeply differs between CHH and KS at puberty, with both testosterone and estradiol being very low only in CHH. At present, body skeletal proportions comparison between CHH and KS is not available.Aim: To compare anthropom...

Background: Iron overload disorders (IOD) are associated with a higher occurrence of unbalanced calcium (Ca)-phosphorous (P) metabolism, including hypoparathyroidism (HPT). However, data about prevalence and presentation of HPT in this setting are scanty. A Ca/P ratio <2.32 has been proposed to detect HPT in the general population.Aim: To characterize Ca-P homeostasis, particularly the prevalence of HPT, in a cohort of adult patients with IOD compare...

Objective: Highly Active Antiretroviral therapy (HAART) has been associated with several endocrine abnormalities. Data concerning thyroid dysfunction in HIV are still controversial. The aim of this study was to investigate the prevalence of thyroid dysfunctions and their association with HAART and HIV-infection in a large cohort of HIV-infected patients.Methods: A retrospective cross-sectional study was carried out involving HIV-infected patients whose t...

Background: HIV-infection is associated to an increased prevalence of erectile dysfunction (ED). In HIV-infected men ED seems to be less related to serum Testosterone (T), depending from other factors.Aim: To investigate the role of different components (organic, relational, psychological) of erectile function by using validate questionnaires in HIV-infected men with normal serum T.Methodology: Prospective, cross-sectional, observa...

Background: Primary hyperparathyroidism (PHPT) is the third most common endocrine disorder. The Ca/P ratio is an accurate tool to differentiate patients with PHPT (>3.5 if Ca and P are expressed in mg/dl) from healthy subjects [1]. The reliability of this index is based on the fact that serum Ca and P are inversely related together. However, other disorders of the Ca-P metabolism, such as hypophosphoremia (HypoP), might impair the Ca/P ratio.Aim: To ...

Background: HIV is associated with decreased bone mineral density (BMD) and decreased muscle mass. Osteoporosis and sarcopenia often co-exist and their onset is multifactorial. Sex steroids play a key role in the homeostasis of bone health and body composition in HIV-uninfected men, but data in MLWH are scanty.Aim: To investigate the frequency of low BMD and sarcopenia and their relationship with gonadal function in MLWH younger than 50.<p class="abs...

Background: HIV-infection is associated to an increased prevalence of age-related comorbidities, such as erectile dysfunction (ED) and testosterone (T)-deficiency.Aim: Definition of ED and T-deficiency in HIV-infected men using validated sexual questionnaires and the gold standard assay for T measurement: isotopic dilution–liquid chromatography–tandem mass spectrometry (ID–LC–MS/MS)Methodology: Prospective, cros...

Background: GH–IGF1 status is important for bone health. Acromegaly affects bone status, but less is known on the role of treatments for acromegaly on bone mineral density (BMD). Pegvisomant (Peg) is effective in treating acromegaly by reducing IGF1. As serum GH is not influenced by Peg, it is not known if residual, direct GH effects on bone (not IGF1 mediated) are preserved during treatment.Methods: To evaluate the effects of Peg on BMD, we compare...

Introduction: Thyroid volume (TV) depends on age, gender, anthropometry, smoking and iodine status. IGF1 plays a role on thyroid growth, as demonstrated in acromegaly and GH-deficiency. Finally, TSH is a well recognised permissive factor for thyroid tissue growth. The aim of the study is to evaluate the long-term effect of TSH-deficiency on TV in hypopituitaric patients compared with healthy volunteers.Methods: We performed a cross-sectional, controlled ...

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...
