Introduction: Adolescents are considered the main consumer group of Energy Drinks (EDs). EDs are associated with adverse cardiovascular events, such as severe cardiac arrhythmia or arterial hypertension. Recent studies of our department revealed a significantly increased brachial blood pressure and arterial stiffness after the acute ED consumption in healthy adolescents. Increased central blood pressure is linked with the onset of end-organ damages such as lef...

X-linked hypophosphatemia (XLH) is the most common genetic disorder of phosphate homeostasis. It is caused by inactivating mutations in the PHEX gene, which encodes a phosphate regulating endopeptidase predominantly expressed in osteoblasts, osteocytes, and odontoblasts.In children there is a broad phenotypic spectrum of XLH ranging from isolated hypophosphatemia without clinical signs up to severe symptoms, such as rickets, extreme lower limb d...

Background: TransCon hGH, is a once-weekly prodrug releasing unmodified hGH, for the treatment of Growth Hormone Deficiency (GHD) in children and adults. To date, TransCon hGH has demonstrated comparable efficacy, safety and anti-hGH immunogenic profile to daily hGH, with no occurrence of neutralizing antibodies.Objective and hypotheses: Protein-based therapies may be associated with generation of drug-specific antibodies, which may impact efficacy, part...

Background: Children born small-for-gestational-age (SGA) especially when they experience rapid catch-up growth have an increased risk for obesity and metabolic disturbances later in life.Aims and objectives: Little is known about the effect of catch-down (c-d) growth and its effect on metabolic parameters in children born large-for-gestational-age (LGA).Patients and methods: 101 pre-pubertal children with a birth-weight and/or len...

Background: Gonadotropin releasing hormone analogs (GnRHa) are effective in improving adult height in children with precocious onset of puberty, rapid progression, and good growth potential. In last years, however, some transient metabolic complications have been described during the treatment without the reassurance of long-term data yet. The aim of our study is to clarify if body mass index (BMI) at diagnosis of idiopathic central precocious puberty (iCPP) c...

Background: Hyperphosphatemic conditions such as chronic kidney disease are associated with muscle wasting and impaired life quality. While muscle regeneration relies on myogenic progenitor recruitment, the effects of high phosphate loads on this process has not been investigated in detail. This study aims to clarify the direct effectsof hyperphosphatemic conditions on skeletal myoblast differentiation in an murine cell model system.Material and methods:...

Objectives: Bone health is affected in Type-1-Diabetis (T1D) causing higher risk of hip fractures, prolonged fracture healing and altered bone mineral density (BMD). In T1D adults BMD is found to be decreased. In this study we have measured the BMD in children and adolescents from the Copenhagen Pediatric T1D Cohort.Methods: 276 children and adolescents (131 girls) were included from the diabetes outpatient clinic at Herlev University Hospital. All patie...

Background: Cell-mediated initiation of enchondral ossification is essential for growth plate maturation. The matrix mineralization inhibitors matrix Gla protein (MGP) and osteocalcin (OC) represent key regulators of matrix mineralization and are highly expressed in growth plate chondrocytes. Pharmacological or nutritional phylloquinone (K1) depletion is known to affect skeletal mineralization by reduced gamma-carboxilisation of MGP and OC. Constituents of mineral matrix such ...

Background: Congenital hyperinsulinism of infancy (CHI) is the most common cause for persisting hypoglycaemia in infancy. Genetic causes are mutations in ABCC8 or KCNJ11 (coding for K+ATP-channel subunits), less frequently mutations in GCK or GLUD1. Further genetic examinations are usually performed only if phenotypic aspects point to other specific genes, such as the rare short chain 3-hydroxylacyl-CoA dehydrogenase (<...

Background: Disorders (or differences) of sex development (DSD) are rare congenital conditions in which the development of chromosomal, gonadal, or anatomical sex is atypical. The luteinizing hormone/chorionic gonadotropin receptor (LHCGR) is important for male sex development. LHCGR mutations can cause Leydig cell hypoplasia, which is an autosomal recessive disorder.Objective and hypotheses: We found two heterozygous mutations in the LHCGR, a n...
