Pofi Riccardo , Bonaventura Ilaria , Othonos Nanthia , Marjot Thomas , Moolla Ahmed , Isidori Andrea M , Hodson Leanne , Tomlinson Jeremy W

Objective: Currently, 2–3% of the population of the UK and US receive glucocorticoid (GC) therapy. Significant adverse effects are not confined to chronic use; recurrent short-course administration is associated with increased morbidity and mortality. The efficacy of GC therapy is not in doubt but data about the cumulative dose responsible for adverse effects during GC treatment are still lacking. The aim of this study was to test the impact of 7 days of 10 or 15 mg of Pr...

Risk factors for gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs): a case-control study from NETTARE Unit

Feola Tiziana , Sesti Franz , Puliani Giulia , Sbardella Emilia , Cozzolino Alessia , Lenzi Andrea , Faggiano Antongiulio , Isidori Andrea M , Giannetta Elisa

Introduction: GEP-NENs represent a heterogeneous group of neoplasms with increasing incidence in the last years. Pathogenesis and risk factors of sporadic GEP-NENs are not clear and still debated. The aim of this study is to evaluate the main risk factors for sporadic GEP-NENs in patients followed by the NETTARE Unit (NeuroEndocrine TAsk force of of ‘Sapienza’ University of Rome).Methods: We performed a case-control study including 32 consecuti...

Presentation, clinical features and long-term follow-up of Leydig cell tumours of the testis: 77 cases from a single center experience

Isidori Andrea M. , Giannetta Vincenzo , Gianfrilli Daniele , Lauretta Rosa , Tarsitano Maria Grazia , Fattorini Giorgio , Pofi Riccardo , Pozza Carlotta , Lenzi Andrea

Introduction: With the improved imaging techniques, Leydig cell tumours (LCTs) are frequently found, accounting up to 22% of testicular tumours. The natural history of LCTs is relatively unknown, because of the small size and heterogeneity of available studies. Since LCTs are often removed, long-term follow-up is missing. The aim of this study was to report the experience with a large cohort of prospectively collected LCTs.Materials and methods: Patients...

Effects of somatostatin analogs on glucose metabolism in acromegalic patients: a meta-analysis of prospective interventional studies

Feola Tiziana , Cozzolino Alessia , Simonelli Ilaria , Sbardella Emilia , Puliani Giulia , Giannetta Elisa , Pasqualetti Patrizio , Lenzi Andrea , Isidori Andrea M

Introduction: Glucose metabolism impairment is a common complication of acromegaly. Somatostatin analogs (SSAs) are used as both first and second line treatment. The effect of SSAs on glucose metabolism in acromegaly is still debated.Aim: To address the following questions: 1) do SSAs affect glucose metabolism? 2) does the effect correlate with disease control? 3) do different SSAs – Lanreotide (LAN) and octreotide LAR (OCT) – affect metabolism...

Quantitative analysis of the pituitary gland at magnetic resonance imaging in obese patients

Puliani Giulia , Lubrano Carla , Fiorelli Marco , Sbardella Emilia , Graziadio Chiara , Gianfrilli Daniele , Lenzi Andrea , Isidori Andrea M

Background: Hypothalamic-pituitary function and adipose tissue are deeply interconnected. Obesity has been linked to morpho-functional changes in several endocrine glands (thyroid, adrenal, gonads). No study has quantified the appearance of the pituitary gland in obese subjects.Aim: To measure pituitary signal intensity, homogeneity and texture of the pituitary gland at magnetic resonance (MR) in obese subjects free of focal pituitary disease.<p clas...

Systemic epidermal growth factor receptor-targeted gene delivery using the theranostic sodium iodide symporter (NIS) gene in an advanced orthotopic tumor model

Urnauer Sarah , Morys Stephan , Muller Andrea M , Oos Rosel , Carlsen Janette , Bartenstein Peter , Wagner Ernst , Spitzweg Christine

The well characterized sodium iodide symporter (NIS) in its dual function as reporter and therapy gene displays an outstanding opportunity to target different cancer types allowing non-invasive imaging of functional NIS expression and therapeutic radionuclide application. We recently reported induction of tumor-selective accumulation and therapeutic efficacy of radioiodide after systemic non-viral epidermal growth factor receptor (EGFR)-targeted NIS gene delivery in a subcutan...

External beam radiation therapy: a promising tool to enhance mesenchymal stem cell migration towards tumors

Schug Christina , Wechselberger Alexandra , Urnauer Sarah , Schmohl Kathrin A , Muller Andrea M , Schwenk Nathalie , Lauber Kirsten , Nelson Peter J , Spitzweg Christine

The tumor-homing property of mesenchymal stem cells (MSC) has led to their use as delivery vehicles for therapeutic genes such as the sodium iodide symporter (NIS), which has convincingly been demonstrated by our recent studies of systemic NIS gene delivery using MSCs as delivery vehicles in both subcutaneous and orthotopic xenograft mouse models. External beam radiation therapy (EBRT) represents a promising tool in the application of engineered MSC (eMSCs)-based gene therapy ...

ea0037ep973 | Thyroid (non-cancer) | ECE2015

Morphological and functional alterations of thyroid gland during treatment with tyrosine kinase inhibitors in advanced renal cell carcinoma

Rizza Laura , Giannetta Elisa , Sbardella Emilia , Lauretta Rosa , Gianfrilli Daniele , Lenzi Andrea , Longo Flavia , Isidori Andrea M

Background: Sunitinib (SUN) is a novel oral multitarget tyrosine-kinase inhibitor (TKI) that has demonstrated its efficacy in the treatment of metastatic renal cell carcinoma (mRCC). The thyroid dysfunction is one of the most common side effects of SUN. The mechanisms inducing thyroid dysfunction are still poorly understood.Aim: Identify the incidence, severity, ultrasonographic changes and pattern of response of thyroid function tests during treatment w...

Testosterone supplementation and sexual function: a meta-analysis study

Corona Giovanni , Isidori Andrea M , Buvat Jaques , Aversa Antonio , Ratrelli Giulia , Hackett Geoff , Rochira Vincenzo , Lenzi Andrea , Maggi Mario

Introduction: The role of testosterone supplementation (TS) as a possible treatment for male sexual dysfunction remains questionable. The aim of the present study is to meta-analyse data evaluating the effects of TS on male sexual function and its therapeutic synergism with the use of phosphodiesterase type 5 (PDE5i).Methods: An extensive Medline Embase and Cochrane search was performed including the following words: ‘testosterone’, ‘erect...

Effects of testosterone and sildenafil on cytokines and angiogenic factors: a randomized controlled trial

Isidori Andrea M , Aversa Antonio , Pozza Carlotta , Giannetta Elisa , Spera Gianni , Bonifacio Vincenzo , Fabbri Andrea , Lenzi Andrea

Ageing in men is accompanied by a decline in serum testosterone (T) levels and increased risk of cardiovascular disease, osteopenia, visceral obesity and impaired metabolism. These conditions have complex aetiologies that may share a common pro-inflammatory state. We investigated the impact of T therapy on cytokines and angiogenic factors involved in atherosclerosis and bone loss, in hypogonadal men who underwent androgen replacement. We carried out a 6 months, randomized, dou...
