Severe Neonatal Donohue Syndrome: Extreme Hyperinsulinemia, Progressive Hypertrophic Cardiomyopathy (HCM) and Failure to Thrive

Lämmer Constanze , Langer Johanna , de Potzolli Brigitte , Liebl Stefanie , M.K. Völkl Thomas

Introduction: Donohue syndrome (DS) is presenting as the most severe form of insulin resistance. Most of the patients are dying within the first two years of life. As potential treatment has been described the administration of rhIGF1 (Mecasermin) to stimulate the pathway of insulin-like action. An improved metabolic control was reported with continuous subcutaneous administration of rhIGF1 instead of twice daily injections [Plamper 2018].<p class="abstext...

Prevalence and determinants of hyperuricemia in a Belgian multi-ethnic inner-city population of overweight/obese children and adolescents

Nauwynck Elise , Vanbesien Jesse , Staels Willem , Ryckx Sofie , Verheyden Stefanie , Rutteman Bart , Weets Ilse , De Schepper Jean , Gies Inge

Background/ Aims: Hyperuricemia (HU) is a frequent finding in childhood obesity, ranging between 12 and 40%, and associates to a variable extent with different components of the metabolic syndrome (MS). In this study, the effect of gender, (a Belgian native vs a non-Belgian native) descent and degree of general and central adiposity on serum uric acid (SUA) and the prevalence of HU was investigated in a multi-ethnic population of overweight/obese children and ...

Expression of Type 1 Insulin-like Growth Factor Receptor (IGF-1R) in Liver of Obese Children with Non-alcoholic Fatty Liver Disease (NAFLD)

Pampanini Valentina , De Stefanis Cristiano , Alisi Anna , Inzaghi Elena , Nobili Valerio , Cianfarani Stefano

Background: Type 1 insulin-like growth factor receptor (IGF-1R) is the product of a single-copy gene located on chromosome 15 and is ubiquitously expressed in humans. Increased hepatic IGF-1R gene expression is found in hepatocellular carcinoma and in chronic hepatitis C, making parenchymal and non-parenchymal cells more susceptible to the mitogenic effects of IGF-1.Objective and hypotheses: As we have previously demonstrated that IGF-1 and IGF-2 circula...

Long-term GnRHa use and bone health in transgender adolescents: can a mouse model inform clinical practice?

Ciancia Silvia , Dubois Vanessa , Claessens Frank , Craen Margarita , Doms Stefanie , El Kharraz Sara , Kim Nari , Klink Daniel , Vanderschueren Dirk , Cools Martine

Background: Transgender individuals increasingly present at gender services in childhood. Consequently, to suppress pubertal development, more adolescents are long-term exposed to gonadotropin-releasing hormone analogues (GnRHa), from onset of puberty until start of gender-affirming hormones (GAH), around 16 years. Prolonged GnRHa may compromise bone health more than shorter-term treatment. If earlier start of GAH, when psychologically indicated, may partially...

Monogenic obesity in children: focusing on SH2B1 deletion

Giannopoulou Eleni Z , Zorn Stefanie , Schirmer Melanie , Herrmann Gloria , Heger Sabine , Reinehr Thomas , Denzer Christian , Rabenstein Hannah , Schnurbein Julia von , Wabitsch Martin ,

Introduction: Monogenic obesity refers to a group of rare, early-onset forms of obesity and accounts for about 7% of patients with severe pediatric obesity. Recent reports demonstrate the emerging role of Src-homology-2 (SH2) B adaptor protein 1 (Sh2b1), an important component in the leptin-melanocortin pathway, as a key regulator of leptin and insulin signaling, with possible roles in the pathogenesis of obesity and diabetes. SH2B1 deletions are found to be a...

Earlier Occurrence of Puberty and Pubertal Hair Development in Boys and Girls - Insights from the DPV Initiative Data

Reschke Felix , Gohlke Bettina , Lanzinger Stefanie , Boettcher Claudia , Gemulla Gita , Thiele-Schmitz Susanne , Dunstheimer Desiree , van den Boom Louise , Joachim Woelfle , Reinhard Holl

Introduction: Pubertal onset is signaled by thelarche (in girls) and gonadarche (in boys) and indicates the beginning of the hypothalamic-pituitary-gonadal axis activity. Thus, the onset of pubic hair development usually coincides with adrenarche. Girls worldwide are experiencing earlier puberty, but it is uncertain if this trend affects boys, or if it applies to children with type 1 diabetes (T1D).Aim: The aim of this s...

Diagnostic value of soluble LEPR levels in the serum of patients with disease-causing biallelic LEPR variants

Zorn Stefanie , Tews Daniel , von Schnurbein Julia , Flehmig Bertram , Pridzun Lutz , Wabitsch Martin , Malene IV , Chantana Yay , Khun Leang Chhun , Ban Manet , Tyla Martin , Ngee Lek

Introduction: The soluble leptin receptor (sLR) is the main binding protein of leptin in the serum. It reflects the amount of membrane-bound leptin receptors (LEPR) as the sLR is produced by proteolytic cleavage of the extracellular domain of membrane-bound LEPR. Low sLR but high leptin levels were measured in patients with severe obesity. In patients with monogenic obesity caused by biallelic LEPR variants, sLR levels were found to be either undetect...

Investigation of GNAS Variations as Causes of Monogenic Obesity in Qatar: An Integrative Approach Utilizing In Silico, In Vivo, and In Vitro Studies

Background: GNAS (Guanine Nucleotide-Binding Protein, Alpha Stimulating) is an imprinted gene that encodes the alpha subunit of the stimulatory G protein (Gsa), which mediates the signaling of various G protein-coupled receptors. Inactivating genetic and epigenetic changes in GNAS, leading to Gsa deficiency, are associated with different subtypes of pseudohypoparathyroidism, which may include severe, early-onset obesity ...

Background: The ‘External Masculinization Score’ (EMS) is an objective method of scoring undervirilized genitalia in infants but may require further adaptation to capture the appearance of the genitalia more comprehensively across the phenotypic spectrum.Objective: To develop and validate a non-binary, standardized score that describes the range of appearance of external genitalia.Method: The external genitalia score (EGS...
