BACKGROUND: The aim of this study was to investigate systolic pulmonary artery pressure (SPAP) and echocardiographic findings in patients with euthyroid Hashimoto's thyroiditis (HT). METHODS: Thirty (8 male, 22 female, mean age 47.4+/-10.5 yr) consecutive patients with euthyroid HT and 30 (9 male, 21 female, mean age 46.4+/-10.7 yr) healthy controls were included in the study. Transthoracic echocardiography was performed for all patients and levels of thyroid hormones, thyroid autoantibodies, glucose, insulin, urea, and creatinine were compared...

BACKGROUND: A number of recent advances in our understanding of thyroid physiology may shed light on why some patients feel unwell while taking levothyroxine monotherapy. The purpose of this task force was to review the goals of levothyroxine therapy, the optimal prescription of conventional levothyroxine therapy, the sources of dissatisfaction with levothyroxine therapy, the evidence on treatment alternatives, and the relevant knowledge gaps. We wished to determine whether there are sufficient new data generated by well-designed studies to provide reason to pursue such therapies and change the current standard of care...

BACKGROUND: Autoimmune thyroid diseases are the most common of all autoimmune diseases. In the literature, Hashimoto thyroiditis (HT) is considered to be a T-helper (Th) type 1 dominant condition, and Graves disease is considered a Th2-dominant condition. OBJECTIVE: The aim of this study was to highlight a new aspect of the relationships among Th cell subgroups by determining the incidence of autoimmune thyroid disease in patients with allergic rhinitis (AR). METHODS: Patients were diagnosed with AR based on their medical histories, physical examinations, and skin-prick test results in an outpatient clinic...

Thyroid functional disease, and in particular hypothyroidism, is highly prevalent among chronic kidney disease (CKD) and end-stage renal disease (ESRD) patients. In the general population, hypothyroidism is associated with impaired cardiac contractility, endothelial dysfunction, atherosclerosis and possibly higher cardiovascular mortality. It has been hypothesized that hypothyroidism is an under-recognized, modifiable risk factor for the enormous burden of cardiovascular disease and death in CKD and ESRD, but this has been difficult to test due to the challenge of accurate thyroid functional assessment in uremia...

BACKGROUND: As defined by the Dietary Supplement Health and Education Act 1997, such substances as herbs and dietary supplements fall under general Food and Drug Administration supervision but have not been closely regulated to date. We examined the thyroid hormone content in readily available dietary health supplements marketed for "thyroid support." METHODS: Ten commercially available thyroid dietary supplements were purchased. Thyroid supplements were dissolved in 10 mL of acetonitrile and water with 0...

Background: The fact that serum thyrotropin (TSH) levels increase with age may influence the diagnosis of thyroid diseases in older adults. This study aimed to establish an age-specific serum TSH reference range, examine the prevalence of thyroid diseases in older adults ≥65 years, and analyze the risk factors. Methods: A cross-sectional study of adult populations in 10 cities in China was conducted from 2010 to 2011. A total of 15,008 subjects were randomly selected and completed the present study. Urinary iodine concentration, serum TSH, thyroid peroxidase antibody (TPOAb), and thyroglobulin antibody (TgAb) titers were measured...

BACKGROUND: This study aimed to characterize the frequency of self-reported thyroid-related impaired sex life in patients with thyroid diseases, to examine its clinical correlates and relationship with overall quality of life (QOL), and to investigate the effect of treatment. PATIENTS AND METHODS: Two separate patient samples with benign thyroid diseases were investigated: a cross-sectional sample (759 women and 118 men) treated at two Danish university hospital outpatient clinics, in 2007-2008, and a longitudinal sample (358 women and 74 men) undergoing treatment at the abovementioned centers, during 2008-2012, evaluated before and 6 months after therapy...

For a long time it has been known that both hypo- and hyperthyroidism are associated with an increased risk of morbidity and mortality. In recent years, it has also become clear that minor variations in thyroid function, including subclinical dysfunction and variation in thyroid function within the reference range, can have important effects on clinical endpoints, such as bone mineral density, depression, metabolic syndrome, and cardiovascular mortality. Serum thyroid parameters show substantial interindividual variability, whereas the intraindividual variability lies within a narrow range...

BACKGROUND: Small cross-sectional studies have suggested that metformin, a first-line oral hypoglycemic agent, may lower thyroid-stimulating hormone (TSH) levels. Our objective was to determine whether the use of metformin monotherapy, when compared with sulfonylurea monotherapy, is associated with an increased risk of low TSH levels (<0.4 mIU/L) in patients with type 2 diabetes mellitus. METHODS: Using the Clinical Practice Research Datalink, we identified patients who began receiving metformin or sulfonylurea monotherapy between Jan...

CONTEXT: Hypothyroidism is a common endocrine disorder frequently accompanied by alterations in lipid metabolism, such as hypercholesterolemia and high circulating triglycerides, both risk factors for nonischemic cardiomyopathy. Rodent studies suggest that the hypothyroid state promotes cardiac lipid retention by increasing lipid uptake into cardiomyocytes while reducing fatty acid oxidation. Furthermore, increased cardiac lipid load has been linked to cardiac dysfunction. OBJECTIVE: Dyslipidemia and hypothyroidism frequently coexist; thus, we hypothesized that overt hypothyroidism causes cardiac lipid deposition and ultimately cardiac dysfunction...

Thyroid hormone deficiency can have important repercussions. Treatment with thyroid hormone in replacement doses is essential in patients with hypothyroidism. In this review, we critically discuss the thyroid hormone formulations that are available and approaches to correct replacement therapy with thyroid hormone in primary and central hypothyroidism in different periods of life such as pregnancy, birth, infancy, childhood, and adolescence as well as in adult patients, the elderly, and in patients with comorbidities...
