Selenium supplementation could restore euthyroidism in subclinical hypothyroid patients with autoimmune thyroiditis
Intriduction: The thyroid is an organ with one of the highest selenium concentrations, containing many selenoproteins implicated in thyroid hormone metabolism. Treatment with levothyroxine has been recommended for all subclinical hypothyroid patients with TSH levels > 10 mU/L, whereas for those with TSH < 10 mU/L treatment remains controversial. Aim: A randomised controlled prospective study was performed to investigate the effects of Se treatment on patients with ...

A concise review of Hashimoto thyroiditis (HT) and the importance of iodine, selenium, vitamin D and gluten on the autoimmunity and dietary management of HT patients.Points that need more investigation
Hashimoto's thyroiditis (HT) is a chronic autoimmune thyroid disease caused by an interaction between genetic factors and environmental conditions, both of which are yet to be fully understood. The management of HT depends on its clinical manifestations, commonly including diuse or nodular goiter with euthyroidism, subclinical hypothyroidism and permanent hypothyroidism. However, in most cases ...

THYROID STATUS, INSULIN SENSITIVITY AND GLUCOSE TOLERANCE IN OVERWEIGHT AND OBESE ADULTS BEFORE AND AFTER 36 WEEKS OF WHEY PROTEIN SUPPLEMENTATION AND EXERCISE TRAINING
Research suggests that subclinical hypothyroidism influences insulin sensitivity and glucose tolerance. Reductions in thyroid stimulating hormone concentrations are associated with exercise training, which improves insulin sensitivity and glucose uptake. Purpose—A secondary analysis of a previously published data was conducted to examine the relationship between subclinical hypothyroidism, thyroid stimulating hormone, and ...

Vitamin A Affects Flatfish Development in a Thyroid Hormone Signaling and Metamorphic Stage Dependent Manner
Vitamin A (VA) and retinoid derivatives are known morphogens controlling vertebrate development. Despite the research effort conducted during the last decade, the precise mechanism of how VA induces post-natal bone changes, and particularly those operating through crosstalk with the thyroid hormones (THs) remain to be fully understood. Since effects and mechanisms seem to be dose and time-dependent, flatfish are an interesting study model as they undergo a characteristic process of ...

A 2016 Italian Survey about the Clinical Use of Selenium in Thyroid Disease
Selenium (Se) is a trace element that plays key roles in thyroid physiology. Se deficiency is associated with increased risk of thyroid disease. Some evidence suggests that Se supplementation may be beneficial in autoimmune thyroid disease (either hypo- or hyperthyroidism). Objectives: We sought to examine the use of Se in daily clinical practice among Italian endocrinologists. Methods: Members of the Associazione Medici Endocrinologi (AME) were invited to participate in a web-based survey investigating the use of ...

25-Hydroxyvitamin D serum level in Hashimoto’s thyroiditis, but not Graves’ disease is relatively deficient
Vitamin D is a modulator of both the innate and adaptive immune system. As vitamin D deficiency was a risk factor for some autoimmune diseases, we aimed to evaluate the serum vitamin D levels in autoimmune thyroid diseases (AITD) including Graves’ disease (GD) and Hashimoto’s thyroiditis (HT) and investigated the association between serum vitamin D levels and AITD. 175 AITD patients including 51 GD, 61 euthyroid HT (mild HT), 63 euthyroid HT patients with hypothyroidism ...

Iodine supplementation during pregnancy of hypothyroid women treated with L-thyroxine neither influences neonatal TSH nor prevents decrease in maternal free thyroid hormone concentrations in second and third trimesters
Introduction: Pregnant women require about 250 μg of iodine daily. Hypothyroid women treated with L-thyroxine do not utilise iodine, and metabolism of L-thyroxine tablets is an additional source of iodine for their foetuses. The aim of the study was to evaluate the influence of iodine supplementation in hypothyroid pregnant women treated with L-thyroxine on neonate TSH ...

Meta-Analysis of the Association between Vitamin D and Autoimmune Thyroid Disease
Although emerging evidence suggests that low levels of vitamin D may contribute to the development of autoimmune disease, the relationship between vitamin D reduction and autoimmune thyroid disease (AITD), which includes Graves’ disease (GD) and Hashimoto thyroiditis (HT), is still controversial. The aim was to evaluate the association between vitamin D levels and AITD through systematic literature review. We identified all studies that assessed the association between vitamin D and AITD from PubMed, Embase, ...
