Starting recombinant human growth hormone treatment at an early age improves adherence and catch-up growth in patients with growth disorders, and highlights the importance of the new guideline on referral of short children to paediatric care

van Dommelen Paula , Zoonen Renate van , Vlasblom Eline , Wit Jan M. , Beltman Maaike , Arnaud Lilian , Koledova Ekaterina ,

Background: The new preventive child health care guideline for referral of short/tall children facilitates early detection of growth disorders. Understanding the impact of early treatment initiation on recombinant human growth hormone (rhGH) adherence and catch-up growth can support the use of the guideline.Aim: To evaluate the impact of age at rhGH treatment start on adherence (≥85% vs <85% of prescribed doses...

Long-term GH-treatment of children born small for gestational age (SGA) does not result in cerebrovascular abnormalities in adulthood compared to untreated controls

Dorrepaal Demi , Goedegebuure Wesley , Smagge Lucas , van der Steen Manouk , van der Lugt Aad , Hokken-Koelega Anita

Background: Increased cerebrovascular morbidity and mortality was reported in adults who were treated with growth hormone (GH) during childhood, including those born SGA, compared to the general population. However, previous studies did not have an appropriate control group of untreated SGA adults which was a major limitation.Objective: To assess cerebrovascular abnormalities (aneurysms, previous intracerebral hemorrhage...

Integrated care for childhood obesity within the medical and municipal domain

van Mil Edgar , Koetsier Leandra , Seidell Jaap , Sijben Marian , Stroo Judith , van der Velde Marian , Halberstadt Jutka

Childhood obesity is a chronic disease with detrimental effects on health and wellbeing. Treatment was traditionally focused on reducing caloric intake and increasing energy expenditure. However, considering the global increase in prevalence in obesity, especially in the paediatric age range, this approach is insufficient and transition to new initiatives is needed. Obesity is a complex disease resulting from the interaction of multiple underlying factors, including personal c...

Phenotypic and genotypic characterization and long-term follow-up of patients with thyroid hormone resistance

Van der Auwera Tessa , Breckpot Jeroen , Unuane David , Nauwynck Elise , Van Crombrugge Paul , Decallonne Brigitte , Rochtus Anne

Background: Resistance to thyroid hormone (RTHβ) is a rare disease caused by an inactivating mutation in the thyroid hormone receptor beta gene (THRB). This condition leads to elevated thyroid hormone levels with non-suppressed TSH levels. The clinical phenotype is highly variable, ranging from asymptomatic to signs of hyperthyroidism and/or hypothyroidism. This study analysed the genotype and phenotype of paediatric and adult patients followed in three B...

Optimizing the timing of highest hydrocortisone dose in children and adolescents with 21-hydroxylase deficiency

Context: Children with 21-hydroxylase deficiency (21OHD) require chronic glucocorticoid administration to substitute glucocorticoids and suppress adrenocorticotropic hormone-induced hyperandrogenemia. There is still no evidence about the best timing of the highest hydrocortisone (HC) dose. Administration of the highest dose in the morning aims to mimic the physiological rhythm of cortisol, while a high dose late in the evening may inhibit the early-morning inc...

Changes in Waist-to-Height Ratio during Preschool Years Differ between Children being Obese or Overweight at Five Years of Age Compared with not Overweight Children

Lindholm Annelie , Roswall Josefine , Almqvist-Tangen Gerd , Alm Bernt , Dahlgren Jovanna , Bergman Stefan

Background: Growth patterns in early childhood are important for predicting adult overweight or obesity. BMI is the most widely used measure. However BMI does not reveal much regarding the distribution of fat, for example the visceral fat that in adults is highly correlated with metabolic risk. Waist-to-Height Ratio (WtHR) is in adults a better measure for visceral fat and studies indicate that the same applies to children.Objective and hypotheses: To st...

Growth of Children with Congenital Adrenal Hyperplasia (CAH) During the First 2 years of Life – Data from the Duth Longitudinal Registry

Background: A national database has been developed to register longitudinal data from all CAH children detected through neonatal screening from 2002 onwards. So far, data from 105 children have been registered (65% of Dutch CAH patients) to evaluate treatment and long-term effects in CAH.Aims: To evaluate height and weight in relation to medication used in the first 2 years of life.Methods: Biometric data and medication dosage were...

Clinical phenotyping of patients with genetic obesity

Introduction: In rare cases of obesity, genetic defects lead to hyperphagia and severe early-onset obesity. Genetic testing in patients with a suspected genetic obesity phenotype is important, as it can lead to patient-tailored treatment advice. For children, the Endocrine Society (ES) recommends genetic testing in children with early-onset of obesity (<5 years) and hyperphagia. It is unclear whether these recommendations can also be used in adult obesity c...

Clinical characteristics and response to growth hormone treatment in 27 children and adolescents with pathogenic NPR2 variants

Background: The NPR2 gene plays a critical role in the human growth plate. Pathogenic NPR2 variants can result in varying degrees of short stature. The majority of subjects have no specific clinical findings and are likely classified as idiopathic short stature.Objective: To describe the phenotypic spectrum, analyze genotype-phenotype correlations and assess the response and safety of growth hormone (GH...

Free cortisol and free 21-deoxycortisol in the clinical evaluation of adrenal insufficiency in congenital adrenal hyperplasia

Background: Some patients with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) survive without glucocorticoid treatment, despite low total cortisol levels. This may be caused by accumulating precursor steroids such as 21-deoxycortisol (21DF), which could contribute to the glucocorticoid activity. In addition, these precursor steroids may decrease the cortisol-protein binding, thereby increasing the free (biologically activ...
