To read the full abstract: J Clin Endocrinol Metab 2018;103:1459-1469The ESPE guidelines on CH recommend an initial LT4 dose of 10-15 microgram/kg per day1. Infants with severe CH, defined by a very low pretreatment TT4 or FT4 concentration, should be treated with the highest initial dose. However, little is known about long-term effects on developmental and...

To read the full abstract: Proc Natl Acad Sci U S A. 2018; 115(17): E4091-E4100The hypothalamic-pituitary-adrenal axis is a critical neurohormonal network that regulates homeostasis and coordinates the stress response. Glucocorticoids (GCs) are critical for life and are key regulators of cognitive, metabolic and immunologic homeostasis (4). Clinical studies in healthy human subjects, usi...

To read the full abstract: Nature 2017, 542, 450–455Adipose tissue is no longer considered a passive energy store. Instead, it is well established as an important endocrine contributor. Here, the authors comprehensively show that the function of the adipose tissue as an endocrine organ is not limited to classical adipokines, but also includes miRNAs and maybe other non-coding RNAs. This study...

To read the full abstract: Cell 2017, Volume 171, Issue 2Here, the group of Jerrold Olefsky identified adipose tissue macrophages as important sources of microRNAs regulating metabolic processes not only within the adipose tissue depot, but also in an endocrine way in other distant tissues. The application of exosomes derived from ATMs isolated from obese mice caused insulin resistance both ...

Iodine readily crosses the placenta and is required for the synthesis of thyroid hormones by the fetal thyroid gland. In add...

1.9. IGSF1 mutations are the most frequent genetic aetiology of thyrotropin deficiency

R Fourneaux , R Reynaud , G Mougel , S Castets , P Bretones , B Dauriat , T Edouard , G Raverot , A Barlier , T Brue , F Castinetti , A Saveanu

Brief summary: Congenital central hypothyroidism is caused by thyrotropin deficiency, either isolated or in combination with other pituitary deficiencies. So far, mutations in five genes have been identified in patients with isolated thyrotropin deficiency: thyroid stimulating hormone subunit β (TSHβ), thyrotropin-releasing hormone receptor (TRHR), immunoglobulin superfamily member 1 (IGSF1), transducin-like protein 1 (TBLX1), and ...

Brief summary: This ex vivo/ in vitro study describes a novel regulatory mechanism of androgen receptor (AR) gene transcription by intranuclear actin assembly in droplets upon dihydrotestosterone (DHT) stimulation mediated by DAAM2 (Dishevelled-associated activator of morphogenesis 2) gene.Androgen insensitivity syndrome (AIS) is a common etiology in individuals with 46, XY disorder/differences of sex development, AIS has diverse genita...

Brief summary: This retrospective study compared the efficacy and tolerability profiles of leuprolide and triptorelin in patients with central precocious puberty and did not find any significant difference between the two drugs.Treatment with GnRH analogues represents the standard of care for central precocious puberty (CPP) in order to preserve adult height potential1. Leuprolide and Triptorelin are the most prescribed drugs (1,2). They are g...

Brief summary: This randomized, double-blind, phase 3 trial of youths with inadequately controlled T2D, dulaglutide treatment was superior to placebo in reducing the glycated hemoglobin level at 26 weeks.Comment: T2D in children and adolescents is an aggressive disease with early onset of complications, leading to significant morbidity and mortality. After three decades with no efficient treatment, there is finally light at the end of the tunnel.<p c...

Brief summary: In this cross-sectional study, 11-oxygenated androgens were measured in morning serum samples from 290 healthy adults (125 men, age 22–95 years; 165 women, age 21–91 years) by LC–MSMS (liquid chromatography, tandem mass spectrometry) to generate normative values across the lifespan. In a subset of volunteers (n=83), additional measurements were performed in saliva to assess diurnal and menstrual cycle-dependent variation. In general, it w...
