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: 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: Graves’ disease is an autoimmune disease accounting for the majority of hyperthyroidism cases.Aim: We aimed to assess the interrelationships between cardiovascular risk factors, autoimmunity, insulin resistance and treatment in Graves’ disease.Material and methods: We measured free T3 (FT3), free T4 (FT4), TSH, thyrotropin receptor antibodies (TRAb), anti-thyroglobulin and anti-TPO antibodies, thyro...

Introduction: The interrelationship between autoimmune thyroiditis, Graves’ disease and plasma adipokines levels remains elusive.Aims: We aimed to compare the levels of adiponectin, resistin and PAI-1 levels in patients with autoimmune thyroiditis and Graves’ disease.Subjects and methods: We recorded thyroid function tests, BMI, the levels of total cholesterol (TC), HDL, LDL-cholesterol, triglycerides (TG), apolipoprotein...

Introduction: In patients with autoimmune thyroiditis, thyroid function appears to be related to increased cardiovascular risk. It was our objective to evaluate the relationship between TSH, insulin resistance, lipid profile, C-reactive protein (CRP) and homocysteine in patients with autoimmune thyroiditis (AIT).Methods: We analyzed the lipid profile, the CRP, anti-thyroid antibodies, homocysteine, folic acid, vitamin B12 levels and the insulin resistanc...

Background: Maturity onset diabetes of the young (MODY) has an estimated prevalence of 1–5% in the diabetic population, but misdiagnosis as type 1 or type 2 diabetes is common. It comprises a heterogeneous group of monogenic diseases characterized by primary dysfunction of β cell, young onset, autosomal dominant inheritance, without autoimmunity and without ketosis. Early diagnosis remains a challenge with important future implications, since it allows treatment opti...

Introduction: The Marine–Lenhart syndrome is a rare cause of hyperthyroidism that is associated with the simultaneous or sequential presence of characteristics related to Graves’ disease and toxic nodular or multinodular goiter. It’s validity as a disease is controversial and some authors believe that these are cases of hyperthyroidism where both etiologies coexist. The presence of hyperfunctioning nodules in Graves’ disease patients ranges between 0.8 and ...

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: Quality of life (QoL) and its related physical and psychological symptomatology is an important factor when we treat Graves’ disease.Objective: To analyze the QoL and physical and psychological symptomatology of patients with hypothyroidism after definitive treatment of Graves’ disease.Methods: We evaluated 16 patients with hypothyroidism that previously had Graves’ disease. These patients were submitte...
