Context: Childhood obesity is supposed to affect growth and development in children but there is uncertainty with regard to dynamics and potential causes. We analyzed differences in age-related growth patterns of obese and normal-weight children and their association with circulating endocrine and metabolic factors.Objective/Design: In a large German childhood cohort from Leipzig including 7986 children (22793 data sets) we compared cross-sectional and l...

The Impact of Activating PIK3CA Mutations and PTEN Haploinsufficiency on Human Adipocyte Phenotype and Biology

Kassner Franziska , Handel Norman , Leipert Jenny , Sauer Tina , Wilhelm Franziska , Landgraf Kathrin , Kiess Wieland , Korner Antje , Garten Antje

Background: The phosphatase and tensin homolog (PTEN)/phosphatidylinositol-3-kinase (PI3K)/AKT signaling pathway is central for cell cycle control, differentiation, migration, and metabolism. Unrestricted growth of adipose tissue in particular is frequently seen in humans with germline PTEN and mosaic activating PIK3CA mutations, respectively.Objective and hypotheses: We assume that adipocytes from affected tissue show hyperproliferation and modified dif...

Chronotropic Insufficiency impairs Cardiorespiratory Fitness in Boys and Adolescents with Klinefelter Syndrome

Spiekermann Julia , Höppner Jakob , Sinningen Kathrin , Hanusch Beatrice , Brinkmann Folke , Schündeln Michael M. , Kleber Michaela , Kiewert Cordula , Grasemann Corinna

Background: Klinefelter syndrome (KS) is associated with an increased metabolic and cardiovascular risk profile1,2 and a metabolic syndrome is evident at a prepubertal age in 10% of the affected boys. Boys with KS tend to avoid competitive sports and describe themselves as ‘not good at sports’. Cardiopulmonary fitness in adults with KS has been found to be compromised by chronotropic insufficiency (CI) and a reduced maximal oxygen uptake...

Summary Answer: The majority of the expert panel states that ovarian tissue cryopreservation (OTC)should be offered to young females with Turner syndrome (TS)Background: OTC is a valid option to preserve the fertility of young females at risk of iatrogenic premature ovarian insufficiency (POI). Offering OTC to females with a genetic cause of POI seems a logical next step. One of the most common genetic disorders related ...

Insulin-Like Factor 5 –A Novel Orexigenic Hormone in Humans is Dysregulated in Obesity

Wagner Isabel V , Flehmig Gesine , Scheuermann Kathrin , Loffler Dennis , Korner Antje , Kiess Wieland , Stumvoll Michael , Dietrich Arne , Blueher Matthias , Kloting Nora , Soder Olle , Svechnikov Konstantin

Background: Insulin-like factor 5 (INSL5), a member of the insulin superfamily, is expressed in the colorectum and hypothalamus. INSL5 levels are elevated by prolonged calorie restriction and declined with feeding, suggesting that it might be an orexigenic hormone.Objectives and hypotheses: Our aim was to explore the relationship between INSL5 and different metabolic parameters in lean and obese subjects and to identify possible links between INSL5 and t...

Aberrant expression of agouti signaling protein (ASIP) as a new cause of monogenic severe childhood obesity

Landgraf Kathrin , Kempf Elena , Stein Robert , Hanschkow Martha , Boczki Paula , Kühnen Peter , Kiess Wieland , Blüher Matthias , Körner Antje

Here we identified and characterized a heterozygous tandem duplication at the ASIP (agouti-signaling protein) gene locus causing ubiquitous, ectopic ASIP expression in a female index patient with extreme childhood obesity. In patient-derived adipose tissue samples, we observed pronounced differentiation of stroma-vascular fraction (SVF) cells into adipocytes in the patient compared to normal control cells. We further found reduced mitochondrial maximum respir...

Introduction: The aim of the project “DSDCare” is to implement standardized care for people with DSD following national and international guidelines and to evaluate structural, process and outcome quality of care at 10 specialized centres in Germany from May 2020 till June 2023. Transition from paediatric to adult care is a crucial phase in chronic and rare conditions. In DSD, “loss to follow-up” is usually not associated with acute com...

Background: Klinefelter syndrome (KS) is associated with an increased risk of lower socioeconomic status and a higher risk for morbidity and mortality, which may have a significant impact on quality of life (QOL). The objective of this study is to investigate QOL in a large European cohort of men with KS and associate QOL with socioeconomic status, prevalence of somatic disease and mental illness, testosterone supplementation and age of diagnosis.<p class=...

Compound heterozygous variants in ROBO1 gene cause CPHD and middle line defects

Abstract: Combined Pituitary Hormone Deficiency (CPHD) is characterized by growth hormone and at least one other pituitary hormone deficiency. It is of varying etiology, extent and severity and it usually occurs sporadically with only 10% of cases being familial. Although pathogenic variants in more than 30 genes expressed during the development of the head, hypothalamus and/or pituitary have been identified so far to cause genetic forms of CPHD, the aetiology...

Newborn screening for congenital hypothyroidism through dried blood spot in Low middle income country (LMIC):experience from a tertiary care center

Arif Muzna , Memon Fozia , Humayun Khadija , Kirmani Salman

Background: Neonatal screening is a preventive strategy for various endocrine, metabolic and genetic conditions. Congenital hypothyroidism (CH) is one of the most common preventable and treatable causes of intellectual disability, and delayed diagnosis can lead to disastrous consequences. Incidence of CH is1:3000-1:4000 neonates worldwide but data varies globally. Pakistan lacks a national newborn screening programme for any inherited disease, but Aga Khan Uni...
