We recently assessed systolic heart function in children from IUGR and normal control pregnancies and reported early developmental impairment of left ventricular longitudinal strain – a sensitive echocardiographic measure – during the first 3 months of life in IUGR children. In accordance with previous studies, this suggest that the increased cardiovascular risk later in life imposed by IUGR/SGA may, at least to some extent, be primary and not entirely secondary to...

Background: X-linked hypophosphatemia (XLH) are rare, inheritable disorders caused by excessive renal phosphate wasting manifesting as rickets in children and osteomalacia in adults. While conventional medical treatment with oral phosphate and alfacalcidol is recommended in childhood, where it heals rickets and rescues some of the growth potential prior to fusion of the growth plates, it is controversial whether adults should continue therapy. There is little evidence for the ...

Background: severe primary insulin-like growth factor-1 deficiency (SPIGFD) is a rare growth disorder. Recombinant human insulin-like growth factor (IGF-1) (rhIGF-1; Increlex® [mecasermin]) replacement therapy is EU and US-approved for treating growth failure due to SPIGFD. The long-term therapeutic objective of rhIGF-1 treatment in SPIGFD is to improve adult height (AH). Objective: to describe the characteristics, safety and effectiveness data ...

Background: severe primary insulin-like growth factor-1 deficiency (SPIGFD) is a rare growth disorder, for which insulin-like growth factor-1 (IGF-1) generation test (IGFGT) is debated as a complementary diagnostic analysis. Diagnostic workup for SPIGFD varies geographically and diagnosis is delayed by the rarity of the condition (<1/10,000). Evaluation of real-world practices of IGFGT could help facilitate diagnosis and test use. Objective: to describe rea...

Background: Obesity in childhood is defined by age- and sex-specific BMI cut-off values. However, BMI does not disclose the distribution of fat mass. Increased abdominal adipose tissue is associated with a higher risk of cardio-metabolic disease in adulthood. Thus, precise measurements of abdominal adipose tissue in children may enable early prevention of disease.Objective and hypotheses: To validate measurements of abdominal adipose tissue by anthropome...

Background: Growth during infancy is a continuation of the rapid fetal growth and its regulation is complex and multifactorial. It is well-established that insulin-like growth factor-I (IGF-I) and its regulators (e.g. IGF binding proteins (IGFBP-3) and pregnancy-associated plasma protein-A2 (PAPP-A2)) are important for prenatal and postnatal growth; however, their significance for growth during infancy is not fully explored.Aims: The aim...

Since CGM-based outcomes that are increasingly being used in clinical pediatric diabetes research, this study was aimed at gathering normative sensor data in healthy, non-diabetic children using the recently approved DexCom G6 system. In this multicenter study, healthy, non-diabetic children and adolescents (age 7 to <18 years, BMI between 5th and 85th percentile, and HbA1c <5.7%) were included. Each participant wore a blinded DexCom G6 for approx. 10 days and kept a d...

Background: That mortality is not increased in rhGH-treated patients when adjusting for birth characteristics was recently published (1). When applying a developed mortality model of the general population, the observed and expected deaths in rhGH-treated IGHD, ISS and SGA patients (n=3847) where 21 and 21.99, respectively. The model includes gender, age, calendar year, gestational age (GA), birth lengthSDS (BLSDS), birth weightSDS (BW...

Background: X-linked hypophosphatemia (XLH) are rare inheritable disorders caused by excessive renal phosphate wasting manifesting as rickets in children and osteomalacia in adults. Osteoid accumulates due to the reduced mineralization rate. Based on previous histomorphometric bone biopsy studies it the impression that XLH is a low bone turnover disease. Very little is known about the level of bone markers in XLH and the effects of conventional medical treatment with oral phos...

Background: Prader-Willi Syndrome (PWS), due to loss of expression from genes within the PWS imprinted region at chromosome 15q11.2-13, is characterized by hypotonia and feeding intolerance in infancy with later development of hyperphagia and obesity. Growth hormone improves tone, body composition, and height and can be started in infancy. Morbidity and mortality in PWS include those secondary to hyperphagia and respiratory illness as well as a 17% reported incidence of sudden...
