Introduction: Sirolimus, a mTOR (mechanistic Target of Rapamycin) inhibitor, is well known for its impact on glucides and lipids metabolism. These effects vary according to factors such as dose and treatment duration, species, cell types and environmental factors. In vitro and in vivo, sirolimus inhibits adipogenesis by decreasing adipocytes number and size, as well as pre-adipocytes differentiation, leading to subcutaneous and visceral fat mass decrease in m...

Background: Weight gain in type 1 diabetes (T1D) patients has become a clinical problem due to less strict diets and more stringent glycemic targets. Thus, the number of overweight T1D in the USA increased from 3.4% in 1988 to 22.7% in 2007. Hyperinsulinism is involved in the genesis of obesity but in T1D, the impact of insulin therapy in weight gain is not established. Islet transplantation, now reimbursed in France, makes it possible to interrupt insulin. The aim of this wor...

Introduction: Anti-thyrotropin receptor antibodies (TSHR-Abs) stimulating the thyroid (TSAb) are responsible for Graves’ disease. In some patients, the TSHR-Abs can block thyrotropin action (TBAb) and cause hypothyroidism, the switch between stimulating and blocking activity in Graves’ disease being well. This reports aims to describe clinical presentation of patients affected directly by hypothyroidism.Material and methods: Retrospective clini...

Introduction: Pheochromocytoma and most abdominal paraganglioma (PPGL) can secrete catecholamines. In vitro and in vivo, catecholamines modulate bone remodeling by stimulating bone resorption. In patients with PPGL, four studies have previously demonstrated an increase of biological markers of bone resorption, a decreased of bone density and a higher prevalence of vertebral fractures. We report two patients with malignant abdominal secreting paraganglioma pre...

Purpose: Bone metastases (BM) are frequent in differentiated thyroid cancer (DTC). These patients may present skeletal-related events (SRE), the leading cause of DTC-related morbidity. We aimed to evaluate the clinical features, treatment approaches, and outcomes including overall survival (OS) of DTC patients with BM complicated by SRE and their evolution over time.Methods: 178 consecutive DTC patients harbouring BM were enrolled in this retrospective s...

Introduction: Few studies to date have attempted to evaluate the early efficacy of first-generation somatostatin analogs in somatotroph macroadenomas.Objective: To investigate the short-term efficacy of primary therapy with lanreotide 120 mg on tumor shrinkage and ophthalmologic symptoms in newly diagnosed patients with acromegaly.Design and patients: This single-center retrospective study included 21 patients who were newly diagno...
