ObjectiveSeveral studies showed that patients discontinuing denosumab (Dmab) may experience bone loss and incident vertebral fractures (VFx) due to a rebound bone turnover increase, suggesting the need of anti-resorptive (i.e. bisphosphonate BPs) therapy to mitigate this occurrence. However, the morphometric VFx (morphoVFx) incidence after Dmab discontinuation is unknown and scarce data are available about the BPs effect on BMD changes and Fx risk in thi...

Introduction: Basal calcitonin (bCT) and calcium-stimulated calcitonin (sCT) levels are useful in the management of Medullary Thyroid Cancer (MTC). Nowadays several bCT/sCT cut-offs have been proposed but univocally accepted values are still lacking. We identified gender-specific CT cut-offs in a series of patients who performed calcium gluconate test at our Centre.Methods: Our study includes a total of 35 patients (12 males and 23 females) with thyroid ...

Introduction: Dopamine agonists are the first line treatment for prolactinomas. However, some patients may develop dopamine-agonist-resistant hyperprolactinemia, leading to surgery and/or radiotherapy. The persistence of hypogonadism requires testosterone replacement therapy which could theoretically reduce the efficacy of dopamine agonists due to the conversion of testosterone to estradiol, thus, in turn, increasing the resistance to dopamine agonists. Consequently, in these ...

Introduction: Paragangliomas are rare neuroendocrine tumors, that manifest as painless, slow-growing masses, becoming evident only when symptoms of catecholamine overproduction or mass effects emerge. Paragangliomas exhibit a broad spectrum of characteristics, existing as solitary or multiple entities, and may be sporadic or hereditary. These tumors can be either benign or malignant and have origin in the sympathetic or parasympathetic tissues. Paragangliomas are commonly foun...

Glucocorticoids play a significant role in immune modulation and regulation of inflammation. In patients with endogenous glucocorticoid excess (Cushing’s syndrome [CS]) multiple haematological alterations are recognized, such as neutrophil leukocytosis, lymphopenia, and eosinopenia, often leading to severe clinical complications. However, little is known in patients with mild autonomous cortisol secretion (MACS). Serum inflammation-based scores may reliably reflect system...

We report on the clinical and biochemical outcomes in a 20-year-old male suffering from active craniofacial monostotic fibrous dysplasia (MFD) treated with the RANK-L inhibitor, Denosumab, following unsatisfactory responses to prior long-term bisphosphonates therapy. The patient had been treated over 9 years with pamidronate (cumulative dose of 81 mg), but experienced only mild reductions in pain scores. Following initiation of Denosumab 60 mg subcutaneously, bone pain and bon...

Introduction: The management of patients with adrenal incidentaloma (AI) and possible subclinical hypercortisolism (SH) is debated. This randomized study was aimed to evaluate the effects of adrenalectomy on arterial hypertension (AH).Methods: We consecutively evaluated 590 AI patients (referred to 3 Italian Centres between 06/2016 and 12/2019). Among these, 134 patients showed a possible SH (i.e. 1 mg DST between 1.8 and 5 µg/dl). Based on the excl...

Patients (pts) with adrenal incidentaloma (AI) may show an increased incidence of several cardiovascular risk factors, as obesity, hypertension, diabetes mellitus and dyslipidemia. As previous data suggested that the increased cardiovascular risk in these pts could be in part mediated by alterations of adipokines, this study was aimed to evaluate plasma IL-6, resistin, CT-1 levels in a wide series of pts with AI.Ninety-three pts (42 males; 51 females; ag...

Background: Several criteria (i.e., cortisol supprimibility after 1 mg overnight dexamethasone suppression test -F-dex-, low ACTH levels, high 24 h urinary free cortisol levels -UFC-, high midnight serum cortisol levels) have been used for defining SH. Nevertheless, a real gold standard combination of tests is lacking. Recently midnight salivary cortisol (MSC) has been described as a sensitive marker for the diagnosis of overt hypercortisolism, while the role of MSC in the dia...

Background: Cystic fibrosis-related bone disease (CFBD) is an emerging complication of cystic fibrosis (CF), especially in CF-lung transplant candidates for end-stage disease.Objectives: The assessment of vitamin D levels, bone mineral density (BMD) and morphometric and clinical prevalent fragility fractures in a cohort of young adults affected with CF awaiting lung transplantation for end-stage respiratory failure.Methods: In 42 C...
