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...

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...

HM

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...

Determinants of Advanced Bone Age in Childhood Obesity

Jan de Groot Cornelis , van den Berg Adriaan , Ballieux Bart , Kroon Herman , Rings Edmond , Maarten Wit Jan , van den Akker Erica

Background: Childhood obesity is associated with advanced bone age (BA), leading to an altered growth pattern. Previous results of studies suggest that androgens, estrogens, sex hormone binding globulin (SHBG) and insulin are responsible for this phenomenon, but results are contradictory and might be biased by confounders.Objective and hypotheses: To investigate the independent effects of estrogens, androgens, SHBG and insulin parameters on BA advancemen...

Neonatal Screening for Congenital Hypothyroidism in Ghana: Don’t Take it for Granted!

Ameyaw Emmanuel

In Ghana, iodine deficiency, which represents the most common cause of preventable brain damage in the world, has been virtually eliminated. As a consequence, congenital hypothyroidism (CH) secondary to dysgenesis or enzymatic defects is now likely to be the most common cause of hypothyroidism in neonates. The prevalence of CH in Ghana is however unknown. Based on data in the African American population, it is thought to be less common that in Caucasians.<p class="abstext"...

Abnormal Blood Glucose as a Prognostic Factor for Adverse Clinical Outcome Among Children with Acute Medical Conditions in Ghana

Ameyaw Emmanuel

Background: Abnormal blood glucose in sick children is known to be common and carries a poor prognosis being associated with increased morbidity and mortality.Aim: To compare the clinical outcome in children admitted to the PEU of KATH with normal and abnormal blood glucose (hypoglycaemia or hyperglycaemia).Method: Prospective cohort study involving 430 children, 215 each with normal and abnormal blood glucose, selected from screen...

High Predictability of Impaired Glucose Tolerance by Combining Diagnostic Parameters in Obese Children

Jan de Groot Cornelis , van der Grond Jeroen , Delgado Yosine , Rings Edmond , Hannema Sabine , van den Akker Erica

Background: Current guidelines suggest to test obese subjects with impaired fasting glucose (IFG) by oral glucose tolerance test (OGTT) for the presence of type 2 diabetes. This strategy, however, misses most cases of impaired glucose tolerance (IGT).Objective and hypotheses: To investigate whether combining risk factors improves predictability of IGT in OGTT.Method: In this observational study of 145 overweight children, aged 2.5&...

The effect of GnRHa and testosterone treatment on growth in trans boys

Willemsen Lieve , Boogers Lidewij , Wiepjes Chantal , van Trotsenburg Paul , Klink Daniel , den Heijer Martin , Hannema Sabine

Background: Pubertal growth and adult height are important to many transgender adolescents undergoing medical transition. However, few studies are available on the impact of puberty suppression (PS) with GnRH analogues (GnRHa) and hormonal therapy (HT) with testosterone on growth. In this longitudinal cohort study, we investigated the effect of PS and HT on growth and adult height in transgender boys.Methods: A total of ...

e-REC Capturing The Occurrence and Burden Of COVID-19 Infections In People With Rare Genetic Obesity Disorders

Kerkhof Gerthe , Wabitsch Martin , Bryce Jillian , Johannsson Gudmundur , Ahmed Faisal , van den Akker Erica

Introduction: Following the onset of the COVID-19 pandemic in spring 2020, the European Registries For Rare Endocrine Conditions (EuRRECa), which is a collaboration between Endo-ERN, ESPE and ESE provided the possibility for registration of cases. Obesity is a risk factor for severe COVID-19 disease course in adults. In children and adolescents, COVID-19 disease course is much milder, but has also been identified as risk factor. As rare genetic obesity disorde...

How to interpret growth hormone stimulation test results in children and adolescents with overweight and obesity? A systematic review and meta-analysis and evidence-based proposal for weight-status adjusted cut-offs

Abawi Ozair , Augustijn Dieuwertje , Hoeks Sanne , Rijke Yolanda de , van den Akker Erica ,

Background: Peak stimulated growth hormone (GH) levels are known to decrease with increasing BMI, possibly leading to overdiagnosis of GH deficiency (GHD) in children with overweight and obesity. However, current guidelines do not provide guidance how to interpret peak GH values of these children. The aim of this systematic review and meta-analysis was to study the effect of BMI standard deviation score (SDS) on stimulated peak GH values in children, to identi...
