Longitudinal growth is driven by endochondral ossification at the growth plate, where chondrocytes undergo a well-organized cellular differentiation process from stem-like progenitors to rapidly-proliferating transit-amplifying cells and to hypertrophic chondrocytes. Numerous recent studies have demonstrated that epigenetic modifications play a crucial role in human development and childhood growth. For example, Brachydactyly mental retardation syndrome (BDMR) is caused by hap...

Background: Determining fat mass (FM) using methods of body composition analysis is useful in diagnosis and treatment of obese adolescents who undergo life style intervention. The use of dual-energy X-ray absorption (DXA) is time-consuming, potentially harmful and expensive. Alternative methods for accurately estimating FM are needed.Objective and hypotheses: We evaluated single-frequency arm-to-leg bioelectrical impedance analysis at 50 kHz (sf-BIA) in ...

Background: Recently we demonstrated that male adolescents with severe GHD (sGHD) had a significant decrease of lean body mass and increase in fat mass after stop of GH-therapy. The functional consequence of this observation is unknown.Objective and hypotheses: The aim was to study the changes in parameters of jumping mechanography in adolescents with GHD in the transition period (end of growth) after stop of GH-therapy.Patients an...

Background: Male adolescents with severe GH deficiency show both loss of lean body mass (LBM) and gain of fat free mass (FFM) when off GH treatment. We recently showed that determining gain of FFM and loss of LBM by dual-energy x-ray absorption (DXA) is helpful in the diagnosis of severe GHD during transition as these body composition changes are correlated to the GH-peak of the arginine-GHRH-re-test.Objective and hypotheses: We wanted to explore if the ...

Background: Liraglutide is a glucagon-like peptide analogue which was approved for use in children and young people as an option for managing obesity in December 20201. It is to be used in tier 3 services alongside a reduced-calorie diet and increased physical activity in children more than 12 years if they have a BMI SDS age-equivalent more than 30kg/m2 for adults. We describe our initial experiences of using liraglutide in a tier 3 paed...

Background: Rapid-onset obesity with hypothalamic dysregulation, hypoventilation and autonomic dysregulation (ROHHAD) is a rare syndrome with a high risk of morbidity and mortality. Blood glucose dysregulation is not widely recognised as a feature of ROHHAD and the mechanism is not well understood. We describe glucose dysregulation in two children with ROHHAD syndrome.Case 1: The patient presented at 6 years with rapid w...

Background: Weight loss interventions for obesity have shown variable short-term effects in adolescents and children, but data on longer-term benefits are sparse.Aim: To describe longer-term impact of lifestyle weight loss interventions in adolescent obesity.Method: Obese subjects previously underwent lifestyle weight loss interventions at a hospital-based clinic were invited to participate in metabolic re-assessment. Outcome measu...

Background: People with Down syndrome (DS) are considered to be atherosclerosis-free. However, obesity predispositions and thyroid gland dysfunction that accompanies this syndrome can influence on the heart ischemic risk. The aim of the study was the evaluation of lipid profile of children with DS and estimation of omega-3 supplementation effect on serum lipid profile.Materials and methods: The group constituted 69 children with DS (41 boys), average age...

Background: Long standing GH deficiency (GHD) causes loss of muscle mass. DXA enables the measurement of LBMDXA but is accompanied with a potentially harmful X-ray exposition. BIA measures the electric resistance of the body which correlates with LBM. A comparison of both methods in children with GHD has not been performed yet.Aim: Calculation of a regression formula for LBM using resistance and anthropometry based on LBMDXA in chil...
