Background: Permanent hypoparathyroidism can result from immune-mediated destruction of the parathyroid glands. Alternatively it may result from activating antibodies to the calcium sensing receptor that decrease parathyroid hormone (PTH) secretion. Autoimmune hypoparathyroidism is a common feature of poliglandular autoimmune syndrome type I. Other causes, all very rare, include irradiation and storage of infiltrative diseases of the parathyroid glands. Neurological signs of h...

Introduction and Aim: Dopamine receptor D2 (DRD2) polymorphism (rs1800497) appears to be associated with increased susceptibility to the development of type 2 diabetes mellitus (T2DM). The dopamine transporter (DAT) determines dopamine signalling, responsible for the reuptake of its active form from the synapse. Polymorphism in the DAT gene (rs2836317) can increase dopamine reuptake in the synaptic cleft. However, its association with T2DM is still controversial.<p class="...

IntroductionThe Indoleamine 2.3-dioxygenase (IDO) is an enzyme involved in tryptophan metabolism, encoded by the IDO1 gene in humans. In Caucasians, the rs9657182 polymorphism of IDO gene was found to be associated with neurobehavioral complications, especially depression. Several studies in Type 2 Diabetes Mellitus (T2DM) describe psychological factors as barriers to the successful implementation of a healthy eating plan. According to our knowledge ther...

Background: Hashimoto thyroiditis (HT) is the most common autoimmune disease and patients may present different levels of thyroid dysfunction. The association between hypothyroidism and cardiovascular events is well established. However, it remains unclear how mild thyroid dysfunction, autoimmunity and chronic inflammation in HT contribute to an increased cardiovascular risk in euthyroid patients and in subclinical hypothyrodism. Therefore, this study aims to assess insulin re...

Introduction: Graves’ disease treatment with antithyroid drugs may be associated to several side effects. Vasculitis development is rare.Clinical case: The authors present the history of a 41-year-old woman with Graves’ disease followed at endocrinology consultation since February 2004. Three years and a half after starting treatment with propilthiouracil (PTU), she developed eritematous and itching stains in the inferior limbs that spontaneous...

Background: Bariatric surgery leads to weight loss and to cardiometabolic risk improvement. Although prediabetes remission after bariatric surgery is biologically plausible, data on this topic is scarce.Aim: We aimed to access pre-diabetes remission rate and clinical predictors of remission in a 4 year follow up period.Methods: Observational longitudinal study including patients with morbid obesity and prediabetes submitted to bari...
