White adipose tissue (WAT) stores excess energy as triglycerides, while brown adipose tissue (BAT) dissipates energy through heat, acting as a defense against cold and obesity and as a positive regulator of metabolic functions. The thermogenic function of BAT is mainly regulated by the mitochondrial uncoupling protein 1 (UCP1) in brown adipocytes. Moreover, it has been shown that chronic exposure to glucocorticoids (GC) or synthetic GC receptor (GR) agonists inhibits the activ...

Objective: The impact of first-line somatostatin analogues (SSA) on glucose tolerance in acromegaly was investigated during a 10 year period.Patients: One hundred and twelve patients treated with depot SSA.Outcome measures: Primary outcome measures were fasting glucose levels. Data were analyzed according with baseline glucose tolerance and disease control.Results after 12 months SSA treatment: In the 63 pati...

Elevated insulin levels are correlated with colonic adenomas and carcinomas in the general population. Patients with acromegaly are considered at high risk to develop colonic lesions and have a high insulin levels. To evaluate the role of insulin levels on colonic polyps (hyperplastic, adenomatous, single or synchronous) or adenocarcinoma in acromegaly we designed this analytical, observational, open, prospective, study enrolling 189 patients (100 women, 89 men, age 20–82...

The most frequent cause of death in acromegaly is cardiomyopathy. To evaluate determinants of the acromegalic cardiomyopathy we performed an analytical, observational, open, prospective, controlled study in 205 patients with active acromegaly (108 women and 97 men) and 205 non-acromegalic subjects sex- and age-matched with the patients. We determined the prevalence of Left Ventricular (LV) hypertrophy (LVH), diastolic and systolic dysfunction, by echocardiography- measured LV ...

Objectives: Endogenous Cushing’s syndrome (CS) is a rare, chronic condition that results in high morbidity, caused by prolonged exposure to elevated levels of circulating free cortisol. A previous comparative analysis showed osilodrostat increases the odds of complete response (CR; mean urinary free cortisol [mUFC] ≤ 1.0 x the upper limit of normal) at Weeks 12 and 36 vs metyrapone1; however, analyses were limited by small osilodrostat effective sample si...

Aim: To investigate the relationship between serum growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels, seminal plasma GH and IGF-1 levels, and sperm parameters in acromegalic patients.Methods: A cross-sectional study was conducted on 24 acromegaly patients (acromegaly group), 11 non-functioning adenoma (NFA) patients (NFA group), and 16 healthy men (control group). Seminal plasma GH and IGF-1 levels were measured. Semen parameters and se...

Background: Improving physical manifestations of hypercortisolism is an important treatment goal for patients with Cushing’s disease (CD). In the Phase III LINC 3 study (NCT02180217), osilodrostat therapy, a potent oral 11β-hydroxylase inhibitor, rapidly normalised mean urinary free cortisol (mUFC) in most patients with CD and sustained control of mUFC over a median treatment period of 130 weeks (W). Here we describe concomitant improvements in physical manifestation...

Introduction: Osilodrostat decreases cortisol production by inhibiting 11β-hydroxylase, increasing adrenal hormones above the blockade. Here, we describe these effects of osilodrostat and associated adverse events (AEs). The efficacy and safety of osilodrostat in patients with Cushing’s disease (CD) were confirmed in the published Phase III, prospective LINC 3 study (NCT02180217).Methods: 137 patients with CD (mUFC >1.5x upper limit of norm...

Background: 24-h mean urinary free cortisol (mUFC) and late-night salivary cortisol (LNSC) levels are complementary parameters recommended for screening and monitoring treatment response in patients with Cushing’s disease (CD). In the published core period of the Phase III LINC 3 study (NCT02180217), therapy with osilodrostat (potent oral 11β-hydroxylase inhibitor) produced rapid, sustained reductions in mUFC and LNSC alongside improvements in clinical signs of hyper...

Purpose: The present study aims to investigate the effects of hyperprolactinemia (HPRL) and its pharmacological control with Cabergoline (CAB) on the risk of fractures in male patients affected by prolactinoma.Methods: Observational single-center study was conducted on 39 male patients (median age 49±12,4 y) with prolactinoma, including 37 with macroprolactinoma and 2 with empty sellae. In patients PRL levels at diagnosis (PRL 0’), PRL at evalu...
