Background: Small birth size followed by accelerated weight gain in early life is associated with an increased risk for age-associated diseases, such as cardiovascular disease (CVD) in later life. The underlying causes for this are largely unknown. Leukocyte telomere length (LTL) is a marker of biological age and short LTL is associated with increased CVD-risk. Subjects born small for gestational age (SGA) who remain short are treated with growth hormone (GH) to improve adult ...

Background: In children born SGA with persistent short stature, growth hormone (GH) treatment is an approved therapy for increasing adult height (AH). Some SGA children have an advanced bone age (BA) during GH. Heterozygous mutations in the ACAN-gene have been described in children with idiopathic short stature and advanced BA.Objective and hypotheses: To assess growth during GH treatment with additional GnRHa treatment, in children with ACAN-gene mutati...

Background: Growth hormone treatment (GH) in children with PWS results in an improvement in height velocity, body composition and mental and motor development. Discontinuation of GH after attainment of adult height (AH) leads to a decrease in lean body mass and an increase in body fat percentage, which results in an increased risk of impaired glucose tolerance (IGT) and diabetes mellitus type 2 (DM2). Studies in adults with PWS suggest positive effects of GH, but GH is known t...

Background: Boys with PWS often have unilateral or bilateral cryptorchidism. Prospective studies on the treatment of cryptorchidism in boys with PWS are lacking and there is no treatment consensus among pediatricians and urologists.Objective and hypotheses: We hypothesized that hCG treatment would lead to a scrotal position of the testes in infants with PWS and cryptorchidism. We therefore evaluated the effects of hCG treatment on testis position. Additi...

Background: Subjects born preterm have an increased risk for ageing-associated diseases such as cardiovascular disease (CVD) in later life but the underlying cause is largely unknown. Telomere length (TL) is a usable index for ageing, with shorter TL indicating older biological age. Furthermore, short TL is associated with CVD.Objective and hypotheses: To investigate TL in subjects born preterm compared to term and to assess if TL is associated with risk...

Background and Objectives: Childhood obesity is a global public health threat, with an alarming rise in incidence. Obesity at young age has short-term consequences, as well as long-term morbidity. It is, therefore, important to determine body composition longitudinal throughout infancy and childhood to prevent excess adiposity. Multiple methods are used to determine body composition in infants and young children, but none are described as suitable for longitud...

Introduction: Monitoring steroid hormone levels of children with endocrine disorders, such as congenital adrenal hyperplasia (CAH) and disorders of sex development (DSD), can be challenging. Dried blood spot (DBS) sampling can be helpful for these patients. DBS sampling is less invasive, easier to sample, and simpler to transport and store compared to venous blood sampling. Additionally, DBS sampling can be done at home at any time of the day, thus improving p...

X-linked hypophosphataemia (XLH) is a dominant disorder caused by mutations in PHEX (located at Xp22.1), associated with rickets, lower limb deformities, pain, poor mineralization of the teeth and disproportionate short stature in children. The characteristics and severity of XLH vary between patients. Early diagnosis and specific treatment is usually decisive to improve short and long term patient outcomes. We describe the variability of phenotype in two sisters carrying the ...

Background: Being born small for gestational age (SGA) has been associated with a reduction in health-related quality of life (HRQoL) and more problem behaviour. Growth hormone (GH) treatment, which leads to a significant improvement in adult height (AH), improves HRQoL and decreases problem behavior in SGA children. However, such results are very limited in SGA adults who were treated with GH during childhood.Objective:...

Introduction: Automated insulin delivery has demonstrated improved glycemic control in children and adolescents with type 1 diabetes mellitus (T1DM). The present analysis investigates real-world glycemic outcomes in children and adolescent on the MiniMed™ 780G advanced hybrid closed loop (AHCL) system after switching from MiniMed™ 640G predictive low glucose suspend system (PLGS) or MiniMed 670G hybrid closed loop (HCL) system and calibration-free ...
