Hashimoto's thyroiditis is the most common cause of goiter and hypothyroidism among children and adolescents. Its clinical manifestations and course vary. The objective of this study was to review the clinical and evolutionary characteristics of Hashimoto's disease in the pediatric population. Clinical, analytical, ultrasound, epidemiological, and evolutionary data of patients with autoimmune thyroiditis seen at Hospital Universitario San Juan de Alicante between January 2010 and January 2016 were analyzed...

The prevailing teaching regarding homeostasis, and in particular endocrine homeostasis, includes the fundamental concept of a "set point," which represents a target or optimum level defended by physiological control mechanisms. Analogies for the description and teaching of this concept have included thermostats and cruise controls. We previously demonstrated that such a set-point model of regulation implies that in population data of parameter set point/controlling hormone levels, correlations between the parameter and its controlling hormone must be in the direction of the response of the parameter to its controlling hormone, and that in thyroid homeostasis this relationship is not observed...

Thyroid hormone is a major regulator of metabolism and mitochondrial function. Thyroid hormone also affects reactions in almost all pathways of lipids metabolism and as such is considered as the main hormonal regulator of lipid biogenesis. The aim of this study was to explore the possible involvement of p43, a 43 Kda truncated form of the nuclear thyroid hormone receptor TRα1 which stimulates mitochondrial activity. Therefore, using mouse models overexpressing p43 in skeletal muscle (p43-Tg) or lacking p43 (p43-/-), we have investigated the lipid composition in quadriceps muscle and in mitochondria...

Brominated flame retardants (BFRs) have been shown to disrupt thyroid hormone (TH) homeostasis through multiple mechanisms, including inhibition of enzymes that regulate intracellular levels of THs, such as sulfotransferases (SULTs). The placenta plays a critical role in helping to maintain TH levels during fetal development and expresses SULTs. This is concerning given that disruption of TH regulation within the placenta could potentially harm the developing fetus. In this study, we investigated the effects of two polybrominated diphenyl ethers (PBDEs), two hydroxylated PBDEs, and 2,4,6-tribromophenol (2,4,6-TBP) on TH SULT activity in a choriocarcinoma placenta cell line (BeWo)...

Solid organ transplantation has become a mainstay in the contemporary management of end-stage organ failures fueled by advances in immunosuppression, intensive care and surgical technology. Every year, a vast number of transplantable organs is lost on account of hemodynamic instability in potential brain-dead organ donors. Because of a growing organ shortage, measures that increase total donor supply pools are desperately needed. Thyroid hormone has been identified as an adjunctive therapy in donor management due to its potential for increasing organ supply and is currently endorsed by transplant organizations such as United Network for Organ Sharing (UNOS)...

BACKGROUND: Vitamin D preparations reduce titers of thyroid antibodies in women with autoimmune thyroiditis. The same effect was induced by high-dose, but not moderate-dose-, statin therapy. No previous study has investigated the impact of concomitant treatment with a statin and vitamin D on thyroid autoimmunity. METHODS: The study included three matched groups of women with Hashimoto's thyroiditis and low vitamin D status. Groups B (n = 19) and C (n = 20) were treated with vitamin D (2000 IU daily)...

The role of the thyroid gland in ischemic stroke pathology is not well understood. As thyroid hormones modulate the extracellular matrix, we explored the possible link between them and secreted protein acidic and rich in cysteine like 1 (SC1) - one of the extracellular matrix molecules. In the 81 patients with acute ischemic stroke, serum SC1 levels were much higher compared with 30 control subjects: 4.47 vs 2.43ng/mL (p<0.001). Serum levels of free thyroxine (fT4) were higher in stroke subjects compared to those of controls (p=0...

Thyroid hormones (THs) are involved in the development of lymphoid organs and regulation of immune function in birds. However, their role as an immune-modulator in the hyperthyroid state is still debatable. To explore the interrelationship of thyroxine (T4 ) and the immune system, chicks were divided into three groups. Group I was comprised of control birds, who received the basal diet while group II and III were given diets supplemented with 5 μg and 10 μg thyroxine/kg feed, respectively, from 15 to 28 days of age...

Rectal atresia is a rare anorectal malformation, and its association with other anomalies is even more rare. This study presents a unique case of co-twin in which the surviving newborn male underwent surgery due to rectal atresia. Newborn screening tests identified congenital hypothyroidism. The surgical treatment consisted of three stages and thyroid hormones were replaced.

In Autoimmune disease a combination of infection, genetic and environmental factors causes an autoimmune response to the thyroid gland (characterized by lymphocytic infiltrations), thyroid stimulating hormone receptor (TSHR) and different thyroid antigens. Graves' and Hashimoto disease are autoimmune disorders with genetic predisposition. CD40 that stimulates the proliferation and differentiation of lymphocytes is an essential immunomodulatory component for follicular cells in the thyroid and the cell that present the antigen...

Context: In central hypothyroidism (CeH) free thyroxine (FT4) concentrations are low while TSH concentrations may be low, normal or even slightly elevated due to reduced bioactivity. Congenital CeH (CCeH) may be isolated or part of multiple pituitary hormone deficiency (MPHD). Objective: To test our hypotheses that (1) TSH concentrations have a more U-shaped distribution in children with CCeH compared to children with a normally functioning hypothalamic-pituitary-thyroid-axis, and (2) TSH concentrations in children with CCeH with MPHD are higher compared to children with isolated CCeH...

The safety of bisphenol A (BPA) alternatives has attracted much attention due to their wide use. In this study, we investigated the effects of bisphenol F (BPF), an alternative to BPA, on thyroid hormone (TH) signaling and postembryonic development in vertebrates using T3-induced and spontaneous Xenopus metamorphosis as models. We found that in the T3-induced metamorphosis assay, higher concentrations of BPF (100-10000 nM) antagonized T3-induced TH-response gene transcription and morphological changes including intestinal remodeling in a concentration-dependent manner, whereas 10 nM BPF exerted stimulatory effects on T3-induced integral metamorphosis when inhibited T3-induced TH-response gene transcription, demonstrating TH signaling disrupting effects of BPF...

This study explored the influence of triclosan (TCS) in the absence and presence of sodium fluoride (NaF) on estrogenic activity and thyroid function of adolescent female rats. The results indicated that the individual exposure to TCS evoked a significant decline in T3 and T4 but the levels of estradiol, FSH, and LH were significantly elevated beside marked up regulation of calbindin-D9k and estrogen α mRNA expression. On the other hand, the single exposure to NaF causes insignificant changes in thyroid hormones, but evoked a trend toward an increase in both estradiol and LH levels...

Thyroid hormones play a vital role in the human body for growth and differentiation, regulation of energy metabolism, and physiological function. Hypothyroidism is a common endocrine disorder, which generally results from diminished normal circulating concentrations of serum thyroxine (fT4) and triiodothyronine (fT3). The primary choice in hypothyroidism treatment is oral administration of levothyroxine (L-T4), a synthetic T4 hormone, as approximately 100-125 μg/day. Generally, dose adjustment is made by trial and error approach...

BACKGROUND: There is an ongoing discussion whether thyroid hormones are involved in the development and course of attention deficit/hyperactivity disorder (ADHD). Since obesity is associated with both higher thyroid-stimulating hormone (TSH) and free triiodothyronine (fT3) concentrations and increased rates of ADHD, we hypothesized that overweight children with ADHD show higher TSH and fT3 concentrations compared to overweight children without ADHD. METHODS: TSH, fT3, fT4, and leptin levels were analyzed in 230 children (60...
