Pasireotide, a multireceptor-targeted somatostatin analogue, was approved for the treatment of acromegaly, after being studied in two large, randomised, multi-center clinical trials. We reported the history of a 76 years old man affected by acromegaly, treated with Pasireotide long acting release (LAR) as first line therapy. Acromegaly was diagnosed in 2009, as the result of endocrinological investigation suggested by altered facial appearance and macroglossia. Hormonal assays...

The work-up of Differentiated Thyroid Cancer (DTC) patients includes thyroid surgery, thyroid remnant ablation (TRA) with 131-radioiodine and long life follow-up. 131I-post therapy whole body scan (pT-WBS) and thyroglobulin (Tg) are used in identifying metastatic patients. Some authors suggested to use post-surgical Tg (ps-Tg) values in deciding for or against TRA. The aim of our study was to verify the sensitivity and PPV of 131I-pT-WBS compared to serum Tg levels in detectin...

Introduction: Bone and energy metabolisms are deeply related determining a two-way street aimed in regulating the energy utilization [1]. Mountain ultra-marathons are peculiar aerobic performances hardly proving whole body homeostasis [2]. In this study we aimed at investigating and characterizing the metabolic profile (hormones involved in energy metabolism), the metabolic inflammation profile (adipokines), the bone metabolism (bone turnover markers), and their integration (m...

Introduction: Although underlying mechanisms are largely unknown, bone metabolism is regulated by specific microRNAs and changes in their expression are associated with metabolic bone disorders. Exercise is a determinant of bone metabolism; however, different training protocols differently affect bone. Little is known about the effects of exercise on bone-specific miRNA expression.We studied the effect of a 8-week high-intensity training protocol on circ...

Introduction: New treatments of diabetes, such as dapagliflozin, improve global metabolic status beyond glycemic control.Aim: To evaluate tolerance to dapagliflozin and its effects on metabolic control in type 2 diabetes and obese patients attended in endocrinology offices.Material and method: A prospective study of patients with type 2 diabetes and obesity. In an intra-subject analysis, clinical and analytical data were evaluated ...

Background: Endothelial dysfunction leads to cardiovascular complications in type 2 diabetes mellitus (T2DM), through a reduction of nitric oxide (NO)-mediated relaxation. Phosphodiesterase-5 inhibitors (PDE5i) have hemodynamic effects, improving NO levels.Aim: To investigate if long term, chronic treatment with the PDE5i Vardenafil improves systemic endothelial function in men with T2DM.Methods: A longitudinal, prospective, invest...

Purpose: MicroRNAs (miRNAs) are a fundamental component of gene regulation mechanisms. Presently, altered miRNA patterns of expression have been documented in different human cancers, and they may explain the distinct behavior of pituitary adenomas (PA) and the differences between subtypes. miR-375 can target among other genes to IGF1 receptor (IGF1R) and participes in reprogramming cancer cell metabolism. The aim of this study was to assess the miR-375 role on pathogenesis of...

Purpose: The 2004 edition of the WHO text ‘Histological typing of endocrine tumors’ classified pituitary adenomas (PA) on the basis of their histological and immunohistochemical characteristics. Recent advances on the knowledge of the molecular patterns of these tumours may allow establishing a molecular classification with higher accuracy and specificity than previous one.Methods: Within the pale of the multicenter Spanish Molecular Registry o...

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...

Background: A variety of hormones may be down-regulated in CHF patients. Impaired activity of the GH/IGF-1 axis has been described and is associated with poor clinical status and outcome. Moreover, a decrease in serum T3 is correlated to the severity of the heart disease as assessed by the NYHA classification. Aim of this study was to evaluate a possible correlation between IGF-1 levels and T3 status in a cohort of CHF outpatients.M...
