Background: Graves’ Disease (GD) is one of the most common organ specific autoimmune disorders, being characterized by an abnormal production of stimulating autoantibodies to the thyrotropin receptor (TSHR). Some studies demonstrated that genetic polymorphisms in certain cytokines, namely interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), are associated with a greater susceptibility of developing GD. Our aim was to evaluate ...

Introduction: Hypothyroidism caused by autoimmune thyroiditis (AIT) is a disease that can originate physical, psychological and behavioral symptoms. Quality of life (QoL) and psychopathologial symptoms in thyroid diseases and its relation with thyroid function remains unclear. In hypothyroidism there is a discussion about the normal range of TSH and Free T4 values and in which way its fluctuation influences the patient in its daily activities.Objective: ...

Introduction: Pheochromocytoma is one of the major secondary causes of hypertension. The classic triad of pheochromocytoma symptoms of headache, sweating and tachycardia is not present in a high percentage of patients and is sometimes diagnosed as incidentaloma or atypical presentations.Case report: The authors present a 56-year-old man, with no known diseases, referred to Endocrinology evaluation by incidentaloma of the right adrenal gland, from the Pne...

Introduction: Secondary causes of diabetes refer to a category in which diabetes is associated with other diseases. They are thought to constitute less than 2% of the total cases of diabetes.Case report: A 56 year-old caucasian man, with no relevant medical history, presented to the Emergency Department with fatigue, polyuria, polydipsia, polyphagia and involuntary weight loss (6 kg in two weeks). He was hemodynamically stable and exhibited a glycaemia o...

Introduction: The endocrine system is often affected in the course of HIV infection. However, hypopituitarism and diabetes insipidus are uncommon disorders in these patients and have been related to drugs, infections of the central nervous system and neoplastic infiltration, in extremely rare cases.Case report: We present a case of a 42-year-old man with HIV infection known since 2005, but undergoing antiretroviral therapy only since 2010 (emtricitabine/...

Background: Continuous subcutaneous insulin infusion (CSII), alongside multiple daily injections (MDI) are the most frequent therapeutic of type 1 Diabetes Mellitus (DM). We aimed to evaluate the effects of the transition from MDI to CSII in the treatment of type 1 DM.Patients and methods: This retrospective longitudinal study analysed patients that received treatment with CSII from 2006 to 2014. Our sample had 85 patients, 35 male (41.2%) and 50 female ...

Introduction: Insulinomas are pancreatic endocrine tumors originating in the beta cells, characterized by hypoglycemia resulting from insulin hypersecretion.Objectives: To characterize the demography, the clinical features, imagiological findings and pathological evaluation of the cases of insulinomas identified in the previous 35 years at São João Hospital.Methods: We retrospectively analyzed the cases diagnosed as insul...

Introduction: Obese patients are at an increased risk of develop nonalcoholic fatty liver disease. Evidence supports that bariatric surgery might have an important impact on hepatic profile in obese adults. Literature suggests that bariatric surgery in adolescents might decrease the prevalence of some comorbidities, but information about its impact on liver profile and steatosis and fibrosis risk remains scarce.Aim: To evaluate the impact of bariatric su...

Introduction: Given the significant impact of thyroid function on body weight, energy metabolism and adipocytes physiology, our aim was to study the impact of subclinical thyroid dysfunction in plasmatic levels of adipokines and ICAM-1 (intercellular adhesion molecule 1).Methods: We evaluated 98 patients with autoimmune thyroid disease divided into three groups: 30 who were euthyroid (TSH=0.35–4.94 UI/ml), 35 with subclinical hypothyroidism (hypoSC,...

Introduction: Diabetes is a major risk factor for chronic kidney disease (CKD). Previous studies have shown contradictory results regarding the effect of prediabetes in the development of CKD.Methods: We performed a secondary analysis of the SPRINT trial (Systolic Blood Pressure Intervention Trial) involving 9361 patients without diabetes and with an increased cardiovascular risk (clinical or subclinical cardiovascular disease, estimated glomerular filtr...
