Introduction: The Glucagon-like Peptide(GLP1)-analogue liraglutide is the first drug approved for the treatment of obesity in adolescents in Europe. While clinically relevant effects of liraglutide treatment in adolescents with obesity had been shown in a phase III study, there are no reports about the use under real-life conditions in these patients. Our aim was to report the effect of treatment with liraglutide on body weight loss in a cohort of adolescents ...

Background: The course of type 2 diabetes is more severe among children with obesity than among adults. Therefore, children at high risk for glycemic deterioration should be detected early enough to guide preventive (and interventional) clinical management.Methods: We established age- and puberty-specific reference values for 7 different indexes addressing the insulin response during oral glucose tolerance testing upon 4...

Background: Bone development and remodeling are controlled by the phosphoinositid-3-kinase (PI3K) signaling pathway. We investigated the effects of downregulation of phosphatase and tensin homolog (Pten), a negative regulator of PI3K signaling, in osteoprogenitor cells.Methods: Femura, tibiae and bone marrow stromal cells (BMSCs) from mice with Cre-inducible Pten knockdown in cells expressing the transcription factor Ost...

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 prevalence of pediatric type 2 diabetes (T2D) increased over the last 2 decades, related to the rise in obesity. Meanwhile, treatment options for T2D have evolved considerably. Therefore, we analyzed changes in treatment approaches for pediatric T2D over two decades.Material and Methods: Patients with T2D from 321 pediatric diabetes centers (Austria 24, Switzerland 2, Luxemburg 1, Germany 290) were reco...

Background/Objectives: Obesity poses a major public health concern. Although studies estimate that the heritability of BMI lies around 40–50%, the underlying genetics are still poorly understood. In monogenic obesity, solitary genetic variations significantly increase obesity risk. We therefore aim to (1) report the diagnostic yield of monogenic obesity using exome-wide data in a large cohort of over 500 individuals and aim to (2) improve future diagnost...
