Introduction: Hypophosphatasia (HPP) is a congenital disorder of the bone and mineral metabolism. It is based on mutations in the ALPL gene, which codes for tissue-unspecific alkaline phosphatase (TNSAP). Methods:The casuistic of 3 children with heterozygous ALPL mutation are presented. The patients were identified by laboratory data screening for reduced AP activity at the Children's Hospital of the University Hospital Freiburg....

Background: Hypophosphatemic rickets (HR) comprises a group of inherited forms of rickets characterised by renal phosphate wasting. Taking info account the latest advances in HR therapy, it now becomes of interest to better define the mutational and phenotypic spectra of disease.Objective and Hypotheses: The aim of this study was to clinically characterize and perform genetic analysis of 168 cases with HR.<p class="a...

Homozygous loss-of-function mutations of the calcium-sensing receptor gene (CaSR) are associated with neonatal severe hyperparathyroidism (NSHPT), a life-threatening condition with a challenging treatment approach.We report a 7-day-old-female infant who was admitted to our Pediatric Department due to poor sucking. On examination she was lethargic and hypotonic. Laboratory evaluation revealed extreme hypercalcemia of 23.54 mg/dL (N: 7.6–10.4...

Analysis of Diabetes-Associated Autoantibodies in Children and Adolescents with Autoimmune Thyroid Diseases

Background: Zinc transporter 8 autoantibodies (ZnT8Abs) together with glutamic acid decarboxylase autoantibodies (GADAbs), insulinoma antigen 2 autoantibodies (IA-2Abs) and insulin autoantibodies (IAbs) are markers of type 1 diabetes mellitus (T1DM). We studied the prevalence of ZnT8Ab in children with autoimmune thyroid diseases (AITDs) to assess the association of AITDs and T1DM at the serological level.Methods: The st...

EAP1 Mutations Cause an Impaired Transcriptional Activity on GnRH Promoter that Leads to Self-Limited Delayed Puberty

Mancini Alessandra , Howard Sasha R , Cabrera Claudia P , Barnes Michael R , Heger Sabine , Guasti Leonardo , Ojeda Sergio , Dunkel Leo

Background: The initiation of puberty is orchestrated by the augmentation in the secretion of gonadotropin-releasing hormone (GnRH) from a few thousand neurons located in the hypothalamus. Recent findings identified that the neuroendocrine control of puberty is regulated by a network of transcriptional factors hierarchically organized, but this still remains not fully elucidated. Enhanced At Puberty 1 (EAP1) is one of the main regulators of pubertal onset and it is ex...

Prediction of Adult Height by Artificial Intelligence (AI) through Machine Learning (ML) from Early Height Data

Shmoish Michael , German Alina , Devir Nurit , Hecht Anna , Butler Gary , Niklasson Aimon , Albertsson-Wikland Kerstin , Hochberg Ze'ev

Context: Growth analyses have traditionally been done by either non-structural descriptive statistics or by fitting models. While we usually describe height and weight separately, we assume reciprocity of weight and height on each other. We utilize ML to predict ages 7–18 y height based on height and weight data up to age 6y.Methods: After pre-processing the height and weight, primary and secondary features (height SDS, BMI, growth velocity) of 1596...

Absorption and Excretion of Somapacitan, a Long-Acting Growth Hormone (GH) Derivative

Rasmussen Michael Hojby , Damholt Birgitte Bentz , Helleberg Hans , Bjelke Mads , Suresh Swapna , Juul Rasmus Vestergaard , Hollensen Christian

Background: Somapacitan is a reversible albumin-binding growth hormone (GH) derivative in clinical development for once-weekly administration in patients with GH deficiency (GHD). Clinical data in healthy subjects, and adults and children with GHD showed that once-weekly somapacitan injections were well tolerated with no clinically significant safety or local tolerability issues. A sustained dose-dependent IGF-I response supports a once-weekly treatment regimen.<p class="a...

The Role of Adipocytes in Childhood Precursor Bcell Lymphoblastic Leukemia

Brenner Elena Dorothea , Zinngrebe Julia , Dahlhaus Meike , Meyer Lueder-Hinrich , Wabitsch Martin , Debatin Klaus-Michael , Fischer-Posovszky Pamela

Acute lymphoblastic leukemia (ALL) is the most prevalent cancer in childhood. Over the past decades, survival rates increased, but relapse is still associated with a poor prognosis, especially if the bone marrow (BM) is affected. Marrow adipose tissue (MAT) constitutes a major part of the BM niche, but its impact on normal hematopoiesis versus leukemia initiation, progression and relapse has only recently gained attention. MAT is very sensitive to changes in the patient’s...

GLP-1 Receptor Agonist in a Patient with Craniopharyngioma-Related Obesity

Antoniou Maria-Christina , Diaz-Escagedo Patricia , Bouthors Therese , Elowe-Gruau Eglantine , Stoppa-Vaucher Sophie , Messerer Mahmoud , Hauschild Michael

Introduction: Glucagon-like peptide 1 (GLP-1) receptor agonists have been successfully used in adults with hypothalamic obesity, showing a BMI decrease and metabolic profile improvement. Data on GLP-1 receptor agonist treatment for children and adolescents is limited. Herein, we present a clinical case of a male adolescent treated with GLP-1 receptor agonist for hypothalamic obesity, secondary to craniopharyngioma.Case report: A 15.8 year-old boy (Height...

Background: Nutrient deprivation during early development has been associated with the predisposition to metabolic disorders in numerous epidemiological studies. Experiments with rodents also indicate a developmental plasticity of neuropsychological characteristics following alterations of early postnatal nutrition.Objective: Considering its interaction with metabolism and regulation of appetite and behavior, the endocannabinoid system (ECS) may represen...
