Lindhardt Ljubicic Marie , Siegfried Busch Alexander , Upners Emmie , Bistrup Fischer Margit , Holm Petersen Jorgen , Lau Raket Lars , Frederiksen Hanne , Holm Johannsen Trine , Juul Anders , Hagen Casper P.

Background: Minipuberty denotes a transient activation of the hypothalamic-pituitary-gonadal (HPG) hormone axis in infancy. This activation provides an opportunity to examine the gonadal function in infants suspected of hypogonadism before the axis is silenced during childhood. However, female minipuberty remains poorly elucidated. Objective: The study aimed to evaluate dynamic changes in luteinizing hormone (LH), follic...

Aldosterone and pro-atrial natriuretic peptide kinetics in response to rehydration in children with diabetic ketoacidosis

Burckhardt Marie-Anne , Otto Marije , Gotta Verena , Beglinger Svetlana , Bachmann Sara , Hess Melanie , Rentsch Katharina , Koch Gilbert , Davis Elizabeth , Zumsteg Urs , Jones Tim , Pfister Marc , Szinnai Gabor ,

Background: Diabetic ketoacidosis (DKA), a frequent complication of type 1 diabetes (T1D), is characterized by hyperosmolar hypovolemia. The response of water-regulating hormones to DKA treatment in children is not well known. While arginine vasopressin (AVP) is thought to respond to changes in osmolality, aldosterone and atrial natriuretic peptide (ANP) are expected to respond to volume changes (dehydration and overhydration, respectively). The objective of t...

Evaluation of the potential benefits of biphosphonate treatment on symptomatic vertebral fractures in children treated for acute lymphoblastic leukemia

Diaz Escagedo Patricia , Fiscaletti Melissa , Di Ioia Rose , Perrault Melissa , Olivier Patricia , Dubois Josee , Miron Marie-Claude , Laverdiere Caroline , Hoa Tran Thai , Alos Nathalie ,

Background and Aim: Vertebral fractures (VF) in children with acute lymphoblastic leukemia (ALL) are often symptomatic and impairing life quality. Prevalence of children with VF at ALL diagnosis has been reported as 16% with peak incidence occurring during the first year after diagnosis and a 6-year cumulative incidence of 32.5%. Moreover, only 15.8% of these patients will have vertebral reshaping 24 months after ALL diagnosis. Additionally, 23% of ALL survivo...

Dynamic Changes in Growth and IGF-I During the First Year of Life; A Longitudinal Study of 233 healthy Danish Infants

Upners Emmie N. , Ljubicic Marie L , Busch Alexander S , Fischer Margit B , Almstrup Kristian , Petersen Jorgen H , Jensen Rikke B , Hagen Casper P , Juul Anders ,

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...

GROWPATI Study: Growth and puberty description pattern in a well-characterized cohort of patients with growth retardation due to severe primary IGF1 deficiency

Stoupa Athanasia , Flechtner Isabelle , Viaud Magali , Pinto Graziella , Samara-Boustani Dinane , Thalassinos Caroline , Netchine Irene , Brioude Frederic , Amselem Serge , Legendre Marie , Polak Michel ,

Background: Severe primary insulin-growth factor-1 (IGF1) deficiency (SPIGF1D) is a rare cause of growth delay. The diagnostic criteria include age- and sex-dependent low basal IGF1 concentration (<2.5th percentile), height SDS < -3SDS, absence of growth hormone deficiency and of any secondary causes of growth failure.Objectives: 1) Report the growth pattern and pubertal status 2) Identify the molecula...

Evaluating Safety, Efficacy, and Pharmacokinetics of Weekly TransCon CNP in Children with Achondroplasia: Design of the ACcomplisH Trial

McDonnell Ciara , Irving Melita , Zarate Yuri , B. Hove Hanne , Hogler Wolfgang , Hoernschemeyer Daniel , Zhang Ying , Viuff Dorthe , Hartoft-Nielsen Marie-Louise , Beckert Michael , Savarirayan Ravi ,

Achondroplasia (ACH) is the most common form of dwarfism, occurring in 1: 20,000 births. ACH is caused by gain-of-function mutations in the fibroblast growth factor receptor 3 (FGFR3) gene that interfere with endochondral ossification. Clinically significant morbidities are frequent in ACH; however, there are currently no approved therapies that target the underlying pathobiology. C-type natriuretic peptide (CNP) is an attractive target as it has the potential to inhi...

Dasiglucagon safety in paediatric participants with CHI

Meissner Thomas , D. De León Diva , Thornton Paul , Zangen David , Mohnike Klaus , Andersen Marie , Bøge Eva , Birch Sune , Ivkovic Jelena , Banerjee Indi

Background: Congenital hyperinsulinism (CHI) is a rare disorder, which causes persistent and severe hypoglycaemia in infants and children. CHI can be treated with glucagon, but long-term use is challenging owing to its instability in aqueous solution. Dasiglucagon, a stable glucagon analogue designed for long-term use as a subcutaneous continuous infusion, is in clinical development. Here, we present dasiglucagon safety results in participants treated for up t...

The association of dietary glycemic index and load with insulin sensitivity and secretion from early childhood to late adolescence: the QUALITY cohort

Cattrysse Pascaline , Harnois-Leblanc Soren , Sallah Drammeh Pa , Drapeau Vicky , A. Barnett Tracie , Mathieu Marie-Ève , Suissa Karine , Benedetti Andrea , Henderson Mélanie

Introduction: With the increasing prevalence of obesity, prediabetes and type 2 diabetes (T2D) in youth are on the rise. Prevention is paramount for these multifactorial diseases. Dietary interventions targeting a reduction of dietary glycemic index (GI) and glycemic load (GL) are potential strategies for improving insulin resistance. However, the association between GI and GL and T2D risk in children remains uncertain.Objectives...

Background: Wiedemann Steinert Syndrome (WSS) is characterized by distinctive facial features (hypertelorism, thick eyebrows, long philtrum, broad nasal bridge), growth retardation, and intellectual disability of varying degrees. Affected individuals are often born small for their gestational age and have generalized hypertrichosis. Some have growth hormone deficiency, usually partial with normal pituitary MRI. The disease is caused by autosomal dominant varia...
