Hepatocytes are both insulin sensitive and the primary site for synthesis of SHBG. Thus, it is possible that a condition of hepatic insulin resistance may impair hepatic synthesis of SHBG. In this study, we assessed SHBG circulating levels after 30 days of a very low-calorie ketogenic diet (VLCKD) based on high-biological value protein preparations diet (ISOMED) and natural food in a cohort of insulin-resistant obese male subjects. Moreover, we investigated the effects of expo...

Low levels of testosterone and SHBG levels are often present in subjects with overweight and obesity; functional hypogonadism further alters the metabolic balance and may drag subjects in a sort of vicious cycle, reducing exercise and energy expenditure. The very low-calorie ketogenic diet (VLCKD) has been reported to rapidly reduce body weight, glycaemia and insulinemia, but its effects on total testosterone (TT) and SHBG levels are less clear. We thus aimed to evaluate the r...

Cell therapy is an emerging, realistic treatment for diabetes. First we will quickly review alternative stem cell approaches including autologous Hematopoetic stem cells (CEB Couri JAMA 2009) and allogeneic Mesenchymal stem cells (Prochymal, Osiris Therapeutics, Inc.: Clinicaltrials.gov NCT00690066) as an attempt to cure recent onset type 1 diabetes, before focusing on β cell replacement therapies including an update on composite islet grafts (islets plus stem cells), or ...

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...

This study describes the evolution of retinopathy 5 years after islet transplantation (IT) with the Edmonton protocol in type 1 diabetic patients. Before IT and then yearly for 5 years, 21 patients (13 islet-alone (ITA), 8 islet-after-kidney (IAK)) underwent monitoring of laboratory parameters, continuous 24 h mean blood pressure (24h BP) and 72 h glucose (CGM), as well as complete ophthalmologic examination. Ten of the 21 patients (48%) were insulin-independent 5 years post-I...

Context: Following the recent evolution in therapeutic strategies for GH-secreting pituitary adenomas, determining optimal individualized patient management is now crucial.Objective: To determine whether pre-surgical medical treatment (PSMT) in patients with acromegaly improves surgical outcome and to specify thresholds for such a strategy.Methods and design: This retrospective study included 110 newly diagnosed acromegalic patient...

Context: The influence of beta cell replacement on daily glucose profile in Type 1 diabetes mellitus (T1DM) is not firmly established.Objective: To examine the influence of islet transplantation (IT) on the various component of dysglycemia in T1DM patients.Design, setting and patients: Single arm open labeled study. Twenty-three consecutive patients with T1DM, 11 males and 12 females, 14 non uremic and 9 uremic with a previous kidn...

Objective: To analyze characteristics of patients who had surgery for a GH-secreting adenoma in the past decade in our centre, to evaluate their initial outcome and long-term recurrence rate using stringent criteria and identify potential predictive factors of surgical remission.Methods: This retrospective study included 115 consecutive patients with acromegaly operated at the neurosurgical department of the Timone Hospital Marseille between 1997 and 200...

Background: The treatment landscape for neuroendocrine tumors includes alkylating-agent chemotherapy and peptide receptor radiotherapy (PRRT) with 177Lu-Dotatate. The risk of MDS/AML associated with 177Lu-Dotatate is approximately 2-3%. Several small prior studies have suggested substantially higher rates of MDS/AML (approximately 10%) in patients who have also received alkylating agent chemotherapy with streptozocin or temozolomide, either combined with PRRT or sequentially. ...

Context: Lipodystrophy is characterized by subcutaneous fat loss, fat maldistribution, and metabolic syndrome. We present a novel phenotype of partial acquired lipodystrophy, possibly associated with childhood chemotherapy.Case reports: Two adult female patients that had been exposed to intensive cytostatic treatment in childhood for leukemia and aplastic anemia, respectively, were referred for therapy resistant diabetes. Both patients had distinct parti...
