Does Obesity Need Tertiary Care Provision? – Against !

Kiess Wieland

In view of the high prevalence of obesity in childhood and adolescence treatments of obesity in young ages represent a major burden to the health care systems around the world. However, still treatments are ineffective largely, and little is being done to organize effective prevention and to enhance societal understanding of the complex etiology of the disease. In more developed and industrialized countries, and that is in all of Europe and in North America as well as in Austr...

Early Life Events and Postnatal Effects from Infancy to Childhood

Kiess Wieland

Early life events can profoundly affect an individual's metabolic phenotype, inducing adaptive responses that may be protective in utero but potentially disadvantageous for long-term health. Indeed, environmental cues during sensitive windows of development may result in altered growth and lead to an increased risk of cardiovascular and metabolic alterations later in life. In this talk, I will discuss several models of exposure to early life events, which were the top...

Influence of growth hormone status and glucose metabolism on hs-Troponin T and NT-proBNP levels in a cohort of healthy children (The LIFE child study)

Kiess Alexandra , Kiess Wieland , Vogel Mandy

Background and Objectives: N-terminal-pro hormone Brain Natriuretic Peptide (NT-proBNP) and hs-Troponin T (hs-TnT) are commonly used cardiac biomarkers despite lacking a deeper understanding about influencing parameters especially in the healthy pediatric population. We previously found associations between NT-proBNP and hs-TnT and a child´s age, sex, pubertal status, Body Mass Index (BMI) and serum lipid levels. Subsequently, we explored associations wi...

The Novel Phosphatidylinositol-3-Kinase (PI3K) Inhibitor Alpelisib Effectively Inhibits Growth of PTEN Haploinsufficient Lipoma Cells

Kirstein Anna , Augustin Adrien , Kiess Wieland , Garten Antje

Background and Aim: Germline mutations in the tumor suppressor gene PTEN cause PTEN Hamartoma Tumor Syndrome (PHTS). Pediatric patients frequently develop lipomas. PTEN antagonizes the growth promoting PI3K/AKT/mTOR pathway. There is no current treatment option except surgery. Treatment attempts with the mTORC1 inhibitor Rapamycin could not reverse lipoma growth. Recently, lipomas associated with a related syndrome caused by mosaic activating PI3K mutations (P...

Effects of Glypican-4 Protein on INS1E Cell Viability and Insulin Signalling

Buhl Joseph , Garten Antje , Richter Sandy , Kiess Wieland , Penke Melanie

Background: Glypican-4 is a heparan sulphate proteoglycan. In addition to a membrane-bound glypican-4, a soluble form exists. Human and rodent adipose tissue were identified as source of circulating glypican-4. Glypican-4 serum levels are associated with obesity and insulin resistance, as in type 2 diabetes (T2D). Because of its positive effect on insulin sensitivity, glypican-4 might play a role in the development of obesity, insulin resistance, and T2D. We a...

Congenital Hypothyroidism – Diagnose Early and Keep Going

Sergeyev Elena , Sloltze Anette , Kiess Wieland , Pfaeffle Roland , Koerner Antje

Background: Serious mental and physical retardation are sequelae of untreated congenital hypothyroidism. These complications have become rare since the introduction of neonatal screening in Germany.Case report: Here we report about a girl with congenital hypothyroidism, who suffered from extreme short and thickset stature, rough facial features and straw-like hair at the age of 12 years. She had been detected in newborn screening with a TSH of 132 IU/ml....

Extrahepatic Biliary Atresia in Combination with Toxic Cholestasis Due to Glibenclamide in a Case of Neonatal Diabetes

Kapellen Thomas , Flemming Gunter , Bartelt Heike , Wachowiak Robin , Kiess Wieland

Background: More than 20 gene loci are known to cause monogenic neonatal diabetes today. A definite mutation can be found in 65–70% of all cases. Mutations in the ATP sensitive potassium channel can frequently be treated by sulfonylurea. Glibenclamide is on of the drugs known to inhibit the bile salt export pump (BSEP). However most drug induced cholestasis cases are reported in adults.Objective and hypotheses: Glibenclamide is used frequently to tr...

PTEN germline mutations lead to adipose tissue overgrowth mediated via FOXO1 and SREBP1.

Kirstein Anna , Kehr Stephanie , Nebe Michele , Kiess Wieland , Garten Antje ,

Background and Aim: Pediatric patients with germline mutations in the tumor suppressor gene PTEN (PTEN hamartoma tumor syndrome, PHTS) frequently develop lipomas. PTEN antagonizes phosphoinositide 3-kinase (PI3K) signaling, which can induce adipogenesis upon activation through insulin. The PI3K downstream target AKT can deactivate FOXO1 via phosphorylation, initiating the expression of the lipogenesis activating transcription factor SREBP1. To study t...

Characterization of the Adipose Progenitor Cell Marker MSCA1 in Normal Weight and Obese Children

Hanschkow Martha , Bouloumié Anne , Dietrich Arne , Kiess Wieland , Körner Antje , Landgraf Kathrin

Background: Obesity is characterized by an increase in fat mass caused by an increase in adipocyte number and adipocyte size and is often associated with adipose tissue (AT) dysfunction contributing to metabolic impairment. It is suspected that adipocyte progenitor cells play an important role during healthy and obesity-related AT expansion. Studies in adults showed that the stroma vascular fraction (SVF) of AT is composed of different progenitor cell subpopul...

Pubertal Milestones and Related Hormonal Changes Among Children with Obesity

Stein Robert , Kempf Elena , Gesing Julia , Stanik Juraj , Kiess Wieland , Körner Antje

Background and Objective: Obesity is known to affect pubertal timing. However, existing data are still controversial, observing either delayed or accelerated pubertal onset, especially among boys. Herein, we evaluated pubertal milestones and underlying hormonal changes between lean and obese children.Material and Methods: We examined 13,484 events from 4,855 lean (BMI SDS <1.28) and 1,983 obese (BMI SDS > 1.88) c...
