Introduction and objectives: Hyperglycemia is present in about 25% of hospitalized patients. His control is common deficient. Consequently it increases the average stay, infection rates and mortality. In order to improve we present a comprehensive protocol.Methods: We developed algorithms of subcutaneous insulin therapy for non-critical patients, insulin therapy i.v. for critical patients, management of hypoglycemia, fasting situations, diabetic ketoacid...

Introduction: Ghrelin is a gastrointestinal peptide involved in the regulation of body weight and energy balance. However, its behavior after bariatric surgery and its relationship with other biochemical variables is still under discussion. We aim to undertake a simultaneous evaluation of the changes in ghrelin levels after three types of bariatric surgery and its relationship with different variables.Design: The study included 21 non-obese and 103 morbi...

Introduction: Primary bilateral macronodular adrenal hyperplasia (PBMAH) are adrenocortical tumors leading to adrenal Cushing’s syndrome. Recently, our laboratory has identified the first gene predisposing frequently to PBMAH in adults, named ARMC5 (Armadillo Repeat Containing 5)1. The ARMC5-inactivating mutations identified in leucocyte and tumour DNA in PBMAH patients suggest that ARMC5 is a tumour suppressor gene. However, the mechanisms of action of ARMC5 remain unkno...

Fibrosis represents a major health concern and presently has no successful treatment. Chronic liver fibrosis leads to portal hypertension, cirrhosis, hepatocellular carcinoma and liver failure. Transforming growth factor β (TGFβ), the main profibrogenic factor, mediates its actions mainly through activation of Smad transcription factors. We have previously observed a cross-talk between the thyroid hormone receptors (TRs) and the TGFβ pathway by which the thyroid...

Introduction: Angiopoietins (ANG) -1 and 2, their receptor TIE2, and the vascular endothelial growth factor (VEGF) are involved in the process of angiogenesis. However, their role in the pathogenesis and development of gastroenteropancreatic neuroendocrine tumours (GEP-NETs) is not completely understood. In a previous study of 42 patients with GEP-NET, we observed an elevation of these serum markers, especially in those with metastatic disease. The objective of this study was ...

Diabetes is associated with a greatly increased risk of cardiovascular disease and the advanced glycation end products (AGEs) and their receptors play an important role in these complications.Objective: To study the association between AGEs and sRAGE levels with cardiovascular risk factors in obese and non-obese newly diagnosed type 2 diabetic patients.Material and methods: We conducted a cross-sectional study in subjects with type...

In obesity the combined effects of enhanced food consumption, enhanced oxidative stress and inflammation could increase levels of advanced glycation end products (AGEs) and the action of their receptors.Objective: To study circulating levels of AGEs, soluble RAGE and AGER-1 and their association with insulin resistance and inflammation in young subjects with obesity and normal weight.Material and methods: We conducted a cross-secti...

Introduction: Patients with autoimmune thyroid disease (AITD) exhibit aberrant immune-regulatory mechanisms. Galectins (Gal) are a family of glycan-binding proteins, which have been involved in immune regulation. However, the association of Gal with AITD remains unknown. In this study, we evaluated serum Gal-1 and Gal-9 in patients with AITD.Methods: Peripheral blood samples from 31 patients with Graves’ disease (GD) (14 with untreated hyperthyroidi...

Introduction and objectives: The localization of primary hyperaldosteronism is often difficult. The coexistence of nonfunctioning adenomas is common in patients older 40 years old and small adenomas undetectable by CT could confuse with bilateral hyperplasia. The AVS is considered the ‘gold standard’ test for the location of numerous guides. We describe our experience in a clinical case of primary aldosteronism.Clinical case: We present a 58 ye...

Prevalence of hyperandrogenism (HA) and polycystic ovary syndrome (PCOS) in female to male transsexuals (FMT) is controversial. To known the prevalence of hyperandrogenism and PCOS in FMT, and their relation with insulin resistance (IR) and other cardiovascular risk factors (CVRF), we studied 77 Spanish consecutive FMT cases, the first ones who appeared in our Gender Unit between May 2007 and Dec 2008, aged 18–43 years. The subjects had never received hormonal treatment o...
