Background: Type 1 DM is an autoimmune disease, characterized by destruction of the insulin-producing beta-cells in the islets of Langerhans. The absolute insulin deficiency leads to metabolic imbalance with hyperglycaemia, acidosis and proneness to ketosis. This acute disturbance can change thyroid hormone metabolism.Objective and hypotheses: To examine the influence of metabolic acidosis/ketoacidosis in type 1 DM on thyroid hormone levels.<p class=...

Objective: IGF-1 receptor mutations (IGF1RM) are a rare abnormality; however, affected patients exhibit severe postnatal growth retardations without catch-up growth. Although several cases of IGF1RM have been described, a comprehensive retrospective analysis of the potential benefit of rhGH treatment is still missing. The aim of this study was therefore to investigate baseline auxology, response to rhGH therapy and potential metabolic effects in patients with IGF1RM in compari...

Background: Achondroplasia (ACH), caused by a pathogenic variant in the fibroblast growth factor receptor 3 gene (FGFR3), is characterized by severe growth failure and may be associated with multisystemic complications. The clinical phenotype is variable and relates to deformity of rhizomelic shortened legs, and myelon compression at cranial base and spine. Recent guidelines are published for diagnostic workflow, neurosurgical, orthopaedic and otorhinolaryngol...

Background: Achondroplasia (Ach) is a rare growth disorder caused by a point mutation in the fibroblast growth factor receptor 3 gene that results in dysproportionate extreme short stature and can lead to a wide range of multisystemic complications throughout the individual's life with reduced quality of life. In the past, orthopaedic and neurosurgical therapies have been developed to partially improve mobility, reduce pain and prevent neurological disabi...

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: 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 ...
