Wood Claire , Morrison Niamh , Cole Michael , Donaldson Malcolm , Dunger David , Wood Ruth , Pearce Simon , Cheetham Tim

Methods: Patients commenced 0.75mg/kg carbimazole (CBZ) daily with randomisation to either BR or DT. We examined baseline patient characteristics, CBZ dose, time to serum TSH/FT4 normalisation and BMI Z-score. Results: There were data available from 80 patients (baseline) and 78 patients (61 female) at 6 months. Mean CBZ dose was 0.9 mg/kg/day (BR) and 0.5 mg/kg/day (DT). There was no difference in the time taken for...

Inhibin B in the Diagnosis of Delayed Puberty

Procopiuc Camelia , Gherlan Iuliana , Dumitrescu Cristina , Brehar Andreea , Vladoiu Suzana , Procopiuc Livia , Caragheorgheopol Andra

Background: Existing tests are not 100% accurate in differentiating between isolated hypogonadotropic hypogonadism (HH) and constitutional delay of puberty (CDP) in boys. Inhibin B is a glycoprotein produced by the Sertoli cells and is measurable even before puberty. Its level increases at the beginning of puberty under the influence of FSH.Objective and hypotheses: The levels of inhibin B (InhB) could differentiate between HH and CDP. We aimed to establ...

The Rationale and Design of TransCon GH

Sprogoe Kennett , Beckert Michael , Mortensen Eva , Karpf David B , Leff Jonathan A

Background: The fundamental challenge of developing a long-acting growth hormone (LAGH) is to create a more convenient growth hormone (GH) dosing profile while retaining the excellent safety, efficacy, and tolerability of daily GH. With GH receptors on virtually all cells, replacement therapy should achieve the same tissue distribution and effects of daily (and endogenous) GH while maintaining levels of GH and resulting IGF1 within the physiologic range....

Paternal Isodisomy and Sporadic Pseudohypoparathyroidism I-b

Colson Cindy , Brehin Anne Claire , Abeguile Genevieve , Decamp Matthieu , Richard Nicolas , Kottler Marie-Laure

Background: Patients affected by pseudohypoparathyroidism type 1b (PHPI-b) develop resistance to PTH leading to hypocalcemia and hyperphosphoremia, which is often associated with resistance to TSH. PHP-Ib is associated with methylation changes at one or several differentially methylated regions (DMRs) within the GNAS complex locus, located at 20q13.2–13.3. This locus gives rise to several different transcripts (NESP55, XL, A/B), with varying patterns of imprinted expressi...

Metabolomics in early life and the association with body composition at age 2 years

van Beijsterveldt Inge , Snowden Stuart , Myers Pernille Neve , Fluiter Kirsten de , Brix Susanne , Ong Ken , Dunger David , Hokken-Koelega Anita , Koulman Albert ,

Background and Objectives: Early life might be a critical window for adiposity programming later in life. Metabolic profile in early life may reflect this programming and correlate with later life adiposity. We investigated if metabolic profile at 3 months of age is predictive for body composition at age 2 years and if there are differences between boys and girls and between infant feeding types.Methods: In 318 healthy t...

Competing Paradigms of Obesity Pathogenesis

Ludwig David

Conventional treatment for obesity, founded on the First Law of Thermodynamics, assumes that all calories are alike, and that to lose weight one must ultimately “eat less and move more.” However, this prescription rarely succeeds over the long term. Calorie restriction elicits predictable biological responses – including increased hunger and reduced energy expenditure – that oppose ongoing weight loss. Indeed, the prevailing Energy Balance Model offers ...

Inhibin B- a functional marker to screen gonadal function in CAIS patients?

Introduction and objective: Gonadectomy was carried out for a long time after the diagnosis of complete androgen insensitivity syndrome (CAIS). It is now recommended to leave the gonads in situ in order to guarantee endogenous hormone production. It is unclear how best to clinically monitor testicular function. The aim of the study was to investigate whether inhibin B can be used as a future follow-up parameter to screen for gonadal function in CAIS p...

Serum Estradiol is Associated with Inhibin B in Healthy 1-6 Years Old Girls

Birkebaek Niels H. , Schørring Mia E. , Frederiksen Hanne , Kamperis Konstantinos , Kristensen Kurt , Rittig Søren , Juul Anders , Vestergaard Esben T

Background: The female gonadal axis is activated in mini-puberty and thereafter it is quiescent until puberty. We have shown that many girls with no clinical sign of puberty in the age group 1-6 yr. have a rather strong luteinizing hormone (LH) and follicle stimulating hormone (FSH) response to a gonadotropin releasing hormone (GnRH) test. However, stimulated LH and FSH values decreased in the age interval 1-6 yr and no LH/FSH values rose above 0.43. Serum est...

Antimullerian Hormone and Inhibin B Markers of the Ovarian Reserve After Ovariectomy

Morandi Grazia , Piona Claudia Anita , Ben Sarah Dal , Ramaroli Diego , Cavarzere Paolo , Antoniazzi Franco , Gaudino Rossella

Background: Ovarian reserve is defined as the functional potential of the ovary, which reflects the number and quality of the follicles left in the ovary at any given time. In literature there studies about the evaluation of ovarian reserve after ovariectomy for tumors and cysts, using serum markers, such as inhibin-B, and anti-Mullerian hormone (AMH), combined to ultrasonographic markers, in adult women but none in peri-pubertal girls.Case presentation:...

AMH and Inhibin B Level in Girls with Central Precocious Puberty

Jeong Hwal Rim , Hwang Il Tae , Yi Kyung Hee

Background/aim: Anti – Müllerian hormone (AMH) and Inhibin B (INHB) are considered as possible biomarker of central precocious puberty(CPP). This study investigated serum AMH and INHB level in central precocious puberty andanalyzed clinical factors associated with these two hormone levels.Methods: In total, 48 girls with CPP and 35 age – matched prepubertal girls were enrolled in the study. The subjects were divided into two groups as CPP ...
