Background and Aim: Despite the broad individual variation of pubertal maturation, references traditionally describe growth in relation to just chronological age and not biological age. Hence, growth references for the adolescent period have been of limited usefulness for monitoring individual growth in clinic and for research. Especially for children and adolescents with chronic diseases is there a need to better evaluate if changes in SD-scores just before a...

Hoermann Henrike , El-Rifai Omar , Schebek Martin , Brusgaard Klaus , Bachmann Nadine , Bergmann Carsten , Mayatepek Ertan , Christesen Henrik , Meissner Thomas , Kummer Sebastian

Background: Kabuki syndrome (KS) is a rare multiple congenital malformation and intellectual disability syndrome. KS is caused by pathogenic variants in the genes KMT2D or KDM6A. In 0.3-4% of patients, KS is reported to be associated with hyperinsulinemic hypoglycemia. The objective of this study was to characterize the clinical, biochemical and molecular data of children with KS and hyperinsulinemic hypoglycemia.<s...

The Incidence of Congenital Combined Pituitary Hormone Deficiency in Denmark - a national observational study

Kjersgaard Jakobsen Louise , Beck Jensen Rikke , Holtum Birkebæk Niels , Hansen Dorte , Rønholt Christensen Ann-Margrethe , Thybo Christesen Henrik

Background: Congenital combined pituitary hormone deficiency (cCPHD) is the loss of ≥2 pituitary hormones caused by genetic or prenatal factors.Methods: For the period 1996–2020, patients with cCPHD were identified from the Danish National Patient Registry and the registries at the four Danish hospitals approved for the management of cCPHD. Retrospective hospital file reviews were performed to validate the diagn...

Carriers of CYP21A2 Mutations have Decreased Mortality in Infectious Diseases, Anational Population Registry Study

Nordenstrom Anna , Svensson Johan , Lajic Svetlana , Frisen Louise , Nordenskjold Agneta , Norrby Christina , Almqvist Malmros Catarina , Falhammar Henrik

Background: Congenital adrenal hyperplasia (CAH) is a relatively common monogenic recessive disorder with an incidence of 1/15 000 in most populations. It has been suggested that CYP21A2 deficiency is relatively common because it may confer a survival advantage to be a carrier. Carriers of CYP21A2 mutations typically do not have clinical symptoms but have a defined phenotype. The cortisol response to ACTH stimulation has been shown to be both...

Duration of Exclusive Breastfeeding: ‘Game Changer’ in a Sex-Specific Association Between Cord Vitamin D Status and Infant Linear Growth

Christensen Anna Mathilde Egelund , Beck-Nielsen Signe , Dalgard Christine , Larsen Sos Dragsbaek , Lykkedegn Sine , Christesen Henrik Thybo

Background: Vitamin D deficiency in children clinically manifests as rickets causing growth impairment and bowing of the long bones, potentially increasing the ratio between crown-rump length and length (CRL:L) or sitting height and height (SH:H).Objective and hypotheses: We investigated whether CRL:L in 19-months-olds and SH:H in 36-months-olds were lower with higher cord 25hydroxyvitamin D (25OHD).Method: Participants were includ...

Vitamin D Depletion in Pregnancy Decreases Survival Time, Oxygen Saturation, Lung Weight and Body Weight in Preterm Rat Offspring

Lykkedegn Sine , Sorensen Grith Lykke , Beck-Nielsen Signe Sparre , Pilecki Bartosz , Duelund Lars , Marcussen Niels , Christesen Henrik Thybo

Background: Animal studies suggest a role of vitamin D in fetal lung development although not studied in preterm animals.Objective and hypotheses: We tested the hypothesis that vitamin D depletion does not aggravate respiratory insufficiency in preterm rat offspring. Furthermore, the effects of vitamin D depletion on growth and lung surfactant were investigated.Method: Female Sprague-Dawley rats were randomly assigned low vitamin D...

Automated Greulich-Pyle Bone Age Determinations in Children with Chronic Endocrine Diseases

Choukair Daniela , Huckmann Annette , Mittnacht Janna , Inta Ioana , Klose Daniela , Schenk Jens Peter , Bettendorf Markus , Thodberg Hans Henrik

Background: Prediction of adult height is a standard procedure in pediatric endocrinology, but it is associated with considerable interrater variability.Objective and hypotheses: To compare the new adult height prediction (PAH) method by automated bone age determination (BoneXpert™) with the conventional PAH method by Bayley Pinneau (BP) based on bone age determination according to Greulich & Pyle. Furthermore, to assess measures of bone health ...

Increase in Sclerostin After Rapid Weight Loss in Children

Birkebaek Niels H , Frystyk Jan , Lange Aksel , Holland-Fischer Peter , Kristensen Kurt , Rittig Soren , Vilstrup Henrik , Henning Gronbaek

Background: Sclerostin is secreted by the osteocyte and inhibits bone formation by osteoblasts and is thus a negative regulator of bone formation. In adults, sclerostin levels increase after weight loss, which may be prevented by exercise training. The effect of weight loss on sclerostin in children is unknown.Objective and hypotheses: To compare sclerostin levels in children before and after a 10 weeks stay at a weight loss camp (WLC).<p class="abst...

Cerebral Outcome of Children with Congenital Hyperinsulism

Rasmussen Annett Helleskov , Melikian Maria , Portner Fani , Larsen Anna-marie , Scherderkina Inna , Globa E , Filipsen Karen , Brusgaard Klaus , Christesen Henrik

Background: Congenital hyperinsulinism (CHI) is a rare condition characterized by unregulated secretion of insulin from pancreatic islet β cells. The primary treatment goal is to obtain normoglycemia, since hypoglycemia in the neonatal period can have severe impact on cerebral development.Objective and hypotheses: To assess the cerebral function in children with CHI at follow up.Method: From an international cohort, 40 childre...

Somapacitan, a Once-Weekly Reversible Albumin-Binding Growth Hormone (GH) Derivative, Is Well Tolerated and Convenient in Adults with GH Deficiency (AGHD): Results from a 26-Week Randomised, Controlled Phase 3 Trial

Johannsson Gudmunder , Feldt-Rasmussen Ulla , Holme Haakonsson Ida , Biering Henrik , Rodien Patrice , Tahara Shigeyuki , Toogood Andrew , Hojby Michael

Background: Growth hormone (GH) replacement as daily s.c. injections for patients with adults with GH deficiency (AGHD) can be cumbersome. Somapacitan (Novo Nordisk), a once-weekly reversible albumin-binding GH derivative, has been shown in short-term trials to be well tolerated in healthy adults and in patients with AGHD.Objective and hypotheses: This trial was a multinational, multicentre, randomised (2:1), open-label, active-controlle...
