The mechanisms triggering autoimmunity in the Graves-Basedow disease (GBD) are unknown, although the evidence for a genetic predisposition is well established. The thyrotropin receptor (TSHR) is a good candidate gene.Objectives: To identify the main alleles/haplotypes of the TSHR gene, and to analyze the existence of TSHR susceptibility alleles to the GBD.Material and methods: To establish the main alleles of TSHR gene, 54 polymorp...

We aimed to assess the effect of sleeve gastrectomy (SG) on the metabolic and gut microbiota profiles in non-diabetic obese patients with different grade of insulin resistance (IR).Methods: Prospective study of 22 morbid non-diabetic obese patients (77.2% women, age 47.13±9.51 years, basal BMI 45.59±4.99 kg/m2, 11 IR and 11 non-IR) undergoing SG. A fasting blood sample was collected at baseline and at 6 months post-SG for the determi...

Introduction: In vitro and animal studies have suggested that changes in the secretion of ghrelin, PYY, GLP-1, GLP-2 can influence bone metabolism. An increase in osteoblastic differentiation has been observed after the administration of ghrelin and GLP-1. GLP-2 has been associated with a decrease in bone resorption and PYY inversely with markers of bone formation.Objective: To analyze the association of gastrointestinal hormones with changes in...

Background: Obesity can lead type 2 diabetes (T2D), however there are patients with obesity who present euglycemia. The mechanisms by which T2D appears have not been fully elucidated. Oncostatin m (OSM) is a proinflammatory cytokine, member of the IL-6 family, which is increased in obesity in mice and humans, and impairs browning in mice. Here, we aim at evaluating the potential role of OSM in the development of T2D in patients with obesity.Material and ...
