Background: Overt thyroid dysfunction is associated with an increased cardiovascular risk. The impact of subclinical hypothyroidism and autoimmunity in the increased cardiovascular risk remains controversial. Aim: To evaluate the interrelations between thyroid function, thyroid autoimmunity and cardiovascular risk factors, in patients with autoimmune thyroiditis (AIT).Methods: 353 subjects with AIT were evaluated. We defined three groups based on TSH lev...

Introduction: Cushing’s syndrome is an endocrinopathy characterized by glucocorticoids excess. Adrenalectomy is the recommend treatment for unilateral adrenal Cushing’s syndrome and is usually associated with resolution of the disease.Clinical Case: A 54-year old woman with central obesity (BMI 34.3 kg/m2), diabetes and hypertension had a left adrenal mass of 15 mm and characteristics suggestive of adenoma (Hounsfield unit of <10...

Introduction: Adrenal tumors are usually detected due to clinical manifestations of hormonal hypersecretion or incidental findings on imaging evaluation. Although most incidentalomas are non-functioning adenomas, it is important to appropriately evaluate such masses to exclude hormonal excess or malignancy.Case description: An 81-year old male was admitted to our hospital for fever with 15 days of evolution. The patient also presented chills and loss of ...

Introduction: Adrenocortical carcinoma (ACC) is a rare and aggressive endocrine malignancy with a poor prognosis. Hormone-secreting ACC appear with manifestations of virilization, feminization or Cushing syndrome.Case Report: A 63-year-old woman with no pathological history of relief was referred to Endocrinology evaluation with an history of deepening of the voice since 1-year ago, as well as hair loss and facial and abdominal hirsutism with 6-month evo...

Introduction: Gastroparesis is defined by a delayed gastric emptying without mechanical obstruction. It can be a debilitating complication of diabetes that is poorly understood and has limited therapeutic options.Case reports: 1st case - We report the case of a 34-year-old woman with type 1 diabetes mellitus (T1DM) with diabetic nephropathy and gastroparesis, and a reasonable glycaemic control...

Background: Thyroid hormones modulate the lipoprotein and glucose metabolisms. In hyperthyroidism, insulin resistance is a frequent finding.Aim: To assess interrelationships between thyroid function, autoimmunity, lipid profile, glucose metabolism and other cardiovascular risk factors in patients with Graves’ disease.Methods: We recorded free T3 (FT3), free T4 (FT4), TSH, TSH receptor antibodies (TRAB), parameters of the lipid...

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...

Introduction: Subclinical hypothyroidism appears to be related with an increased risk of cardiovascular disease. It was our objective to evaluate the relationship between autoimmune thyroiditis, subclinical hypothyroidism, and cardiovascular risk factors.Methods: We evaluated thyroid function tests, autoimmunity, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, ApoA1, ApoB, Lp(a), homocysteine, high sensibility CPR, folic acid, vitamin...

Objective: To evaluate the interrelationships between thyroid function, insulin resistance, lipid profile, homocysteine, C-reactive protein (CRP), folic acid, and vitamin B12 levels, in Graves’ disease (GD).Methods: We recorded thyroid function tests, BMI, insulin resistance markers, lipid profile, homocysteine, CRP, folic acid, and vitamin B12 levels, in 104 subjects with GD in the first cycle of treatment with methimazole, 94% of whom were female....

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...
