Objectives: In X-linked hypophosphatemia (XLH), abnormally elevated serum Fibroblast growth Factor 23 (FGF23) results in low renal maximum threshold for phosphate reabsorption, low serum phosphorus, inappropriately normal 1,25-dihydroxyvitamin D, and development of rachitic deformities. The effect of KRN23 on health-related quality of life (HRQL) was assessed.Methods: Open-label KRN23 was given s.c. every 28 days up to four doses to 28 adults with XLH (2...

Background: Weight status in children is commonly defined using BMI (SDS), but this measure is problematic due to the skewness of the BMI distribution and its age-dependant increase. In addition, it is difficult for physicians or parents alike to grasp what a certain value means. Excess body weight (EBW) is frequently used in adult patients in the context of bariatric surgery.Objective and hypotheses: An appropriate definition for the paediatric populati...

Background: Non-high-density lipoprotein cholesterol (non-HDL-C) has been shown to be a suitable predictor of cardiovascular risk.Objective and hypotheses: We aimed to investigate factors influencing non-HDL-C levels in children with type 1diabetes (T1D, registered at the German/Austrian DPV database, n=26358) in order to increase the rare use of lipid-lowering therapies. Recommendations for acceptable (<120 mg/dl), borderline-high (120&#150...

Background: Congenital hyperinsulinism is the most common cause of persistent hypoglycaemia in early infancy. Mutations in the HNF4A gene lead to transient hyperinsulinism in early infancy and maturity-onset diabetes of youth (MODY1), later in life. Fanconi syndrome is a generalised dysfunction of the renal proximal tubule with a loss of glucose, amino acids, phosphate, low molecular weight proteins, bicarbonate and urate, causing growth failure and rickets in childho...

Introduction: Primary empty sella syndrome (ES) is rare in children. Reports relating it with various endocrine manifestations have been published. Asymptomatic cases have also been reported, this questions the existence of causal relationship.Objective: To analyze causal relationship between primary ES and endocrine manifestations in 15 pediatric cases seen in our clinics, and suggest patients follow-up.Population and methods: Ret...

Introduction: Primordial short stature can have many different causes. In addition to maternal factors (e.g. placental insufficiency), genetic or skeletal disorders may be found in the child. It is important to identify the underlying aetiology in time, since not only the risk of diabetes is increased, but also the prevalence of insufficient gonadal function and malignancy, e.g. in mixed gonadal dysgenesis (MGD).Case report: A 19 year old adolescent pres...

Background: Cannabis use has been legalised in four states in USA. However, endocrine effects of marijuana use are largely unknown. Published experiments on animals have suggested that acute cannabis exposure may lead to suppressed thyroid function, but human studies are limited. Of interest, some studies have shown that cannabis has immunomodulatory effects.Objective and hypotheses: We carried out a cross sectional analysis of data by National Health an...

Background and Aim: A substantial proportion of SGA patients have a syndrome underlying their growth restriction. Most SGA cohorts comprise both syndromic (S-SGA) and non-syndromic patients (nonS-SGA) impeding delineation of the recombinant human growth hormone (rhGH) response. We present a detailed characterization of the Belgian SGA cohort and analyze rhGH response based on adult height (AH).Patients & Methods: Cli...

Background: The potential benefit of growth hormone (GH) therapy on health-related QOL (HQoL) of children with short stature related to GH deficiency (GHD) or smallness for gestational age (SGA) has not been well documented.Objective and hypotheses: Our objective was to assess potential disease and treatment related predictors for a poor HQoL in GH treated children. Children with male gender, SGA disorder, greater height deficit at start of GH and poor h...

Background/hypothesis: Congenital hyperinsulinism in infancy (CHI) mainly arises from mutations in ATP-sensitive potassium channel genes. However, the expression pattern of defects can be markedly diverse. In diffuse CHI (CHI-D) all islet cells express gene defects, whereas patients with focal CHI (CHI-F) only express defects in a localised region of islet cells due to loss of a maternally-imprinted locus. Here, we examined the properties of a novel population of CHI islet cel...
