Baseline Adrenal Function by Measurement of Long-term Cortisol Levels in Scalp Hair of Asthmatic Children Using Inhaled Corticosteroids Equals Healthy Controls

Smit Maria , van Leer Ed , Noppe Gerard , de Rijke Yolanda , Hoekx Jurriaan , van den Akker Erica

Background: Inhalation corticosteroids (ICS) as treatment for asthma can interfere with the hypothalamic-pituitary-adrenal axis and could lead to hypocortisolism. The frequency of this systemic side effect and the correlation to ICS usage is still unclear. Given that the cortisol excretion is pulsatile and determined by acute stress and circadian rhythms, the usefulness of tests based on momentary measures, such as saliva or serum are therefore limited. Cortisol levels measure...

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...

Changes in body composition in transgender adolescents during puberty suppression and hormone treatment

Boogers Lidewij , Reijtenbagh Sterre , Wiepjes Chantal , van Trotsenburg Paul , den Heijer Martin , Hannema Sabine

Context: Transgender adolescents can be treated with puberty suppression (PS) using GnRH agonists (GnRHa), and subsequent hormone therapy (HT). Up to this date, it has not been described at what rate body composition in transgender adolescents changes during the first years of treatment. Also, it is unknown whether Tanner stage at which treatment is initiated, might affect this treatment outcome.Methods: Transgender adol...

The narrative of a patient with leptin receptor deficiency: personalized medicine for a rare genetic obesity disorder

S. Welling Mila , Kleinendorst Lotte , M. van Haelst Mieke , L.T. van den Akker Erica

Leptin receptor deficiency is a rare genetic disorder that affects the body’s ability to regulate appetite and weight. For patients and their families, the disorder seriously disrupts daily life, however, little is published about this impact. We here report the experiences of a 10.5-year-old girl with leptin receptor deficiency and her family. The diagnosis of this rare genetic obesity had a deep impact on the life of the child and her family. It led to a better underst...

Cortisol evaluation in 106 neonates born from mothers using corticosteroids during pregnancy. Proposal for practical approach in clinical practice.

Snijder P.M. , Brandsma AE , van Wijk CAM , Baartmans MGA , van der Heyden JC , van den Akker ELT , Sas TCJ

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...

How to Recognize Underlying Somatic Causes of Paediatric Obesity? Performance of the Diagnostic Recommendations of the Endocrine Society Guideline and Suggestions for Improvement

Abawi Ozair , Kleinendorst Lotte , van der Voorn Bibian , Brandsma Annelies , van Rossum Elisabeth , van Haelst Mieke , van den Akker Erica

Background: Underlying causes of obesity are thought to be rare even in specialized paediatric endocrinology clinics. However, evidence is limited. The Endocrine Society (ES) guideline for paediatric obesity makes the following diagnostic recommendations: endocrine evaluation in presence of reduced growth velocity, evaluation of cerebral obesity in presence of CNS injury, re-evaluation of drug choice in patients using antipsychotics. Genetic testing is recomme...

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...

Increased Salivary and Hair Cortisol and Decreased Salivary Alpha-Amylase Concentrations in Obese Prepubertal Girls

Papafotiou Chrysanthe , Christaki Eirini , van den Akker Erica , Wester Vincent , Apostolakou Filia , Papassotiriou Ioannis , Chrousos George , Pervanidou Panagiota

Background: Obesity has been associated with perturbations of the hypothalamic–pituitary–adrenal (HPA) axis and the sympathetic nervous system (SNS). Scalp hair cortisol has been recognized as a reliable index of long-term cortisol concentrations.Objective and hypotheses: Aim of this study was to compare indices of HPA axis and SNS activities, such as, respectively, the salivary cortisol and alpha-amylase diurnal patterns, and their relations i...

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&...

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...
