Introduction: Until recently, bariatric surgery (BS) has been the only option for clinically meaningful weight reduction for adolescents and youth with extreme obesity. Low participation rate in follow-up examinations and low supplement intake after BS in adolescents has been described in literature (PMID: 24048144, 25078533). We developed a structured pre- and post-bariatric surgery program in order to improve follow-up rate and supplement intake in adolescen...

Recently, we identified Neuritin 1 (NRN1) as preferentially expressed in human white compared to brown adipocyte progenitor cells. In mice, Nrn1 deficiency leads to a reduction in body weight, indicating that it might regulate body weight. In this study, we aim to address the function of NRN1 regarding adipocyte metabolism in vitro and in vivo. We used human SGBS preadipocytes as an in vitro model system. NRN1-deficient cells were generated using len...

Thioredoxin Reductase 2 (TXNRD2) Variant As A Cause Of Micropenis, Undescended Testis And Selective Glucocorticoid Deficiency

Patjamontri Supitcha , Lucas-Herald Angela , McMillan Martin , Prasad Rathi , Metherell Louise , McGowan Ruth , Tobias Edward , Faisal Ahmed S.

Introduction: The molecular aetiology of familial glucocorticoid deficiency (FGD) is very heterogeneous. A recent report of a genetic variant in TXNRD2, the gene encoding thioredoxin reductase Type 2, in a South Asian kindred with FGD suggests that the maintenance of redox balance may be critical for adrenocortical function. We present the second report of an individual from another south Asian family harbouring a different pathological variant in <em...

Congenital hyperinsulinism (CHI) is a life-threatening disease and manifests in the majority of cases in the first days after birth. Based on the distribution of affected cells, focal CHI forms are distinguished from diffuse CHI forms. Focal forms occur in most cases due to a paternally inherited heterozygous mutation in a subunit of an ATP sensitive potassium channel (ABCC8, KCNJ11). Within the diagnostic setting, focal forms can be visualized by 18F DOPA PET scan, as a marke...

Reference intervals of serum estradiol during childhood: comparing and reviewing five studies, effects of gender and age

Lamprecht Tabea , Reinehr Thomas , Kleber Michaela , Rothermel Juliane , Schulz Esther , Simic-Schleicher Gunter , Heger Sabine , Holterhus Paul-Martin , Kulle Alexandra

Background: Specific measurement of low serum / plasma concentrations of 17β-estradiol (E2) is important in pre-pubertal and pubertal children in routine paediatric endocrinology. However, there is still a gap in available reference intervals (RIs) for E2 in paediatrics. The study was partially funded by the German Ministry of Health, grant number 2519FSB503.Objective: First, we technically developed a highly sensit...

Implications of parental anxiety, and fear of Hypoglycemia in glucose control of their Children with Type 1 Diabetes

Dominguez-Riscart Jesus , Garcia-Zarzuela AAna , Buero-Fernandez Nuria , Martin-Bravo Enrique , Ruiz-Ocaña Pablo , M Lechuga-Sancho Alfonso

Introduction: Hypoglycemia is the most common acute complication in T1D. It has ominous symptoms and it is potentially fatal. Parents of infants with T1D are instructed in how to avoid, detect and manage these episodes. However, it is well known that many parents develop fear of hypoglycemia (FoH) which may lead to phobic avoidance behaviors such as permanent hyperglycemia and anxiety, losing optimal metabolic control. We aimed to explore how parenting stress ...

Preliminary evidence for a strong effect of leptin on mood and behaviour in patients with congenital leptin deficiency

von Schnurbein Julia , Remy Miriam , Brandt Stephanie , Manzoor Jaida , Kohlsdorf Katja , Mahmood Saqib , Hebebrand Johannes , Wabitsch Martin

Purpose: States of starvation are characterized by reduced physical activity and social withdrawal. The reduction of leptin levels during starvation has been proposed to be a mediator of these changes, therefore we aimed to ascertain if leptin substitution in patients with congenital leptin deficiency (CLD) can increase physical activity and improve mood.Methods: Seven CLD patients were filmed prior to and after short te...

An Investigation Of Androgen-responsive Non-coding RNAs In Boys With Atypical Genitalia Without Genetic Variants in the Androgen Receptor (AR)

Alimussina Malika , McMillan Martin , Chudleigh Sandra , D McNeilly Jane , A Diver Louise , McGowan Ruth , S Tobias Edward , Faisal Ahmed S

Introduction: Recent studies point to the existence of androgen-responsive non-coding (nc) RNAs in peripheral blood mononuclear cells (PBMC) RNA.Aim: To quantify the androgen-responsive gene expression of SNORD5 and RNY5 and investigate their relationship to the testosterone (T) rise following hCG stimulation in boys with no genetic evidence of androgen insensitivity.Methods: 19 bo...

Androgen receptor activity in genital skin fibroblasts in response to dihydrotestosterone, testosterone and androstenedione using the APOD assay

Große-Schute Lea , Kulle Alexandra , Werner Ralf , Hiort Olaf , Drop Stenvert , Schweikert Hans-Udo , Holterhus Paul-Martin , Hornig Nadine

Introduction: Androgens are essential for the development of male sex characteristics. Testosterone (T) production from androstenedione (A) by the Hydroxysteroid 17-Beta Dehydrogenase 3 (HSD17B3) in gonadal Leydig cells triggers the differentiation of the Wolffian ducts into epididymis, vas deferens, seminal vesicles and the prostate. Shortly after, the virilisation of the external male genitalia starts through the conversion of T into dihydrotestosterone (DHT...
