Introduction: Levothyroxine (LT4) tablets are the most used treatment for hypothyroidism worldwide. LT4 tablets should be taken in the morning and have a fasting state. Some patients could be unable to adhere to this recommendation resulting in poor therapy compliance and thyrotropin (TSH) concentration above the upper normal limits. A previous double-blind placebo-controlled trial showed that LT4 liquid could be ingested during breakfast without a significant difference in TS...

Introduction: type 2 diabetes mellitus (T2DM) and hypogonadism are common conditions afflicting the aging male, often present together. The specific role of testosterone (T) replacement therapy (TRT) on glycometabolic profile and body composition, particularly in patients with T2DM, is still the object of an intense debate. The aim of the present study is to meta-analyze the role of TRT in T2DM considering all placebo and non-placebo-controlled randomized clinical trials (RCTs...

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is showing a rapid and continuous evolution in terms of new waves, the spread of variants and the evidence of reinfections. The growing heterogeneity of clinical presentation requires the identification of underlying pathogenic mechanisms to allow a better risk stratification. Previous studies analysed the role of sex hormones in disease severity demonstrating in male patients the association of...

Introduction: Measurement of basal (bCT) and stimulated calcitonin (sCT) after calcium gluconate infusion can help detect early-stage medullary thyroid cancer (MTC). However there are no standardized cutoffs to discriminate between MTC and other thyroid conditions including c-cell hyperplasia. Methods: A retrospective analysis was conducted on 62 consecutive calcium gluconate stimulation tests performed in 2 Italian institutions from 2015 to 2024. Patien...

Bone loss is a frequent complication of aromatase inhibitors (AIs) therapy in women with breast cancer. Bone-active drugs are effective in protecting the skeleton from detrimental actions of AIs. However, bone mineral density (BMD) was the primary end-point in most of published studies, whereas data on fractures were scant and mainly limited to denosumab. In this prospective study, we investigated the effects of denosumab, oral bisphosphonates and intravenous zoledronate on ri...

Introduction: Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a rare cause of Cushing’s syndrome (CS). Some familial forms have been associated to gene ARMC5 (Armadillo repeat-containing protein 5) inactivating mutations. This study aimed to evaluate the prevalence and the complications of ARMC5 mutations in our cohort of patients with bilateral adrenal incidentalomas (BAI).Methods: 72 patients, referred to our Center...

Background: There is growing awareness of skeletal impairment in individuals with Klinefelter syndrome (KS), involving both quantitative and qualitative alteration of the bone as well as an increased prevalence of vertebral fractures (VFs). Beyond hypogonadism, considerable evidence suggests that other factors may be responsible for the skeletal fragility observed in these patients. Abnormal body composition is a common finding in KS subjects, characterized by an unfavourable ...

Background: Testosterone (T) is essential for bone health during all ages, helping to achieve a proper peak bone mass and, later, to maintain bone density and strength. Guidelines on management of male osteoporosis recommend testosterone replacement in young-adult hypogonadal to prevent bone loss and anti-resorbitive drugs in case of high fracture risk, but the role of T replacement therapy (TRT) alone in subjects with late onset hypogonadism is still the object of an intense ...

Background: Osteoporosis is characterized by reduced bone mass and a compromised bone microstructure, leading to increased bone fragility and fracture risk. Currently, the gold standard for diagnosis is the bone mineral density (BMD) measurement by DXA. However, approximately half of fragility fractures occurs in the context of normal or slightly decreased BMD values.Protocol: In this cross-sectional study, we performed an artificial intelligence (AI)-ba...

Background: In patients with Klinefelter syndrome (KS) morbidity and mortality seem to be higher than general population, this depending on a wide number of possible comorbidities. Impaired metabolic profile, increased risk of venous thrombosis and the consequent increase of cardiovascular diseases might play a key role in this condition as well as reduced bone mineral density and higher fracture risk. Nowadays testosterone replacement therapy (TRT) is the first-choice treatme...
