van Hulst Annelienke , Verwaaijen Emm , van den Berg Sjoerd , van Litsenburg Raphaele , Grootenhuis Martha , Fiocco Marta , Neggers Sebastian , van den Heuvel-Eibrink Marry , van den Akker Erica

Background & Aims: Children with acute lymphoblastic leukemia (ALL) frequently receive high doses dexamethasone during treatment, which may induce acute side effects. The aims of the current study were to determine the influence of a five-day dexamethasone course on changes in leptin, fat mass, body mass index (BMI), hunger, sleep and fatigue and to explore the associations between these changes.Methods: Pediatric AL...

Introduction: Children with cancer are at increased risk of endocrine complications, especially children with a brain tumor. One of these late effects includes bone disorders (ranging from low bone mineral density (BMD) to osteoporosis). Children with a suprasellar Low Grade Glioma (LGG) may be especially at risk for bone problems due to exposure to multiple treatment modalities, hypothalamic dysfunction and/or decreased mobility in combination with vision los...

Background and Aims: Type 1 diabetes mellitus (T1DM) belongs to the most common chronic diseases affecting children and adolescents. Technological advances have improved metabolic control over the past decades, thereby decreasing the risk of long-term complications. However, only a minority of patients meets the treatment goals of maintaining a glycated hemoglobin (HbA1c) level below 7.5% (58 mmol/mol). Webdia is an application for mobile devices developed by the fath...

Background: Monogenic diabetes is a heterogeneous group of metabolic disorders resulting from defects in single genes. Over 90% of the subjects remain undiagnosed, mainly because of lack of access to genetic testing.Objective and hypotheses: The aim of our study was to do a comprehensive genetic analysis of the whole pediatric and young adult autoimmune antibody negative diabetes population of Lithuania.Method: 860 children (age 0&...

Evaluation of Medical Treatment in the First 2 Years of Life with a New Dutch National Longitudinal Registry for Children with Congenital Adrenal Hyperplasia (CAH)

Background: Recently, a national database has been developed to register yearly data from all children detected with CAH in the neonatal screening program from 2002 onwards. So far longitudinal data of 105 children have been registered (roughly 65% of Dutch CAH patients) to evaluate medical treatment and long-term effects in CAH. A national CAH work group developed guidelines for diagnostics and follow up in CAH.Objective and hypotheses: Aim of our curre...

Context: Supra-physiological exogenous corticosteroids used during the last months of pregnancy may lead to temporary neonatal adrenal suppression. Little is known about the outcome of neonates from mothers who used corticosteroids during pregnancy.Objective: The evaluation of clinical symptoms and biochemical findings of adrenal suppression in neonates from mothers using corticosteroids during pregnancy.<p class="ab...

Early adrenal activation in boys with Cystic Fibrosis may explain impaired final height

Tamer Gizem , GM Arets Hubertus , K van der Ent Cornelis , M van Santen Hanneke , J van der Kamp Hetty

Background: Rapid BMI increase in early childhood was found to be a contributing factor for impaired final height in boys with Cystic Fibrosis (CF). This may be explained by early adrenarche triggering an accelerated bone maturation resulting in a compromised growth spurt during puberty, comparable to children with SGA. In healthy Dutch boys, adrenarche starts from the age of 9 years with DHEAS ≥ 1 µmol/L. In Dutch girls, the onset of adrenarche is fr...

How Early is 'extreme Early-Onset Obesity'? Results of Comprehensive Growth Curve Analysis to Identify Genetic Obesity Disorders Based on Age of Onset of Obesity

Abawi Ozair , Kleinendorst Lotte , Blankers Lizette , van Haelst Mieke , van der Voorn Bibian , van den Akker Erica

Background: Early-onset obesity is associated with genetic obesity disorders. According to the Endocrine Society guideline for paediatric obesity, genetic screening is indicated in selected cases with age of onset (AoO) of obesity <5 years. However, this cut-off value lacks evidence. Identifying genetic obesity is vital as treatment for leptin-melanocortin pathway disorders becomes available. We aimed to determine whether AoO of obesity is predictive for g...

GATA Transcription Factors in Testicular Adrenal Rest Tumours

Engels Manon , Span Paul , van Herwaarden Teun , Hulsbergen-van de Kaa Christina , Sweep Fred , Claahsen-van der Grinten Hedi

Background: Testicular Adrenal Rest Tumours (TARTs) are benign tumours that frequently occur in male patients with congenital adrenal hyperplasia. They exhibit both testicular and adrenal characteristics, but their aetiology is unknown. Additionally, TART resembles Leydig cell tumours (LCTs), while no marker exist to discriminate between these testis tumours. GATA transcription factors play an important role in eukaryotic development and are expressed in foetal and adult adren...

Brain Structure, Executive Function and Appetitive Traits in Adolescent Obesity

Jan de Groot Cornelis , van den Akker Erica , Rings Edmond , Delemarre-van de Waal Henriette , van der Grond Jeroen

Background: Children with obesity show differences in brain structure, executive function and appetitive traits when compared to lean peers. Results of imaging studies, however, have been contradictory.Objective and hypotheses: To investigate whether childhood obesity is associated with differences in brain structure and whether differences associate with executive function and appetitive traits.Method: A cross-sectional case-contr...
