Background and aims: Glucocorticoid treatment may influence bone and muscle development in patients with congenital adrenal hyperplasia (CAH). This study evaluated bone mineral density (BMD), bone geometry and muscle mass longitudinally throughout childhood.Methods: 18 patients (ten males, eight females) with classical CAH were included. BMD, bone geometry and muscle mass were measured using peripheral quantitative computed tomography (pQCT) in prepubert...

Background: In contrast to hypoglycaemia due to congenital hyperinsulinism, there are patients with a similar metabolic profile of hypoketotic hypoglycaemia, but low insulin levels and relatively low glucose requirements to maintain euglycaemia. So far, four patients with activating mutations in the insulin signal-transducing kinase AKT2 have been described, each also showing a syndromic phenotype including hemihypertrophy.Objective and hypotheses: We pr...

Background: Mutations in the PPARG gene, encoding peroxisome proliferator-activated receptor-gamma (PPARG) are associated with Familial lipodystrophy type 3. PPARG regulates fatty acid storage and glucose metabolism. The genes activated by PPARG stimulate lipid uptake and adipogenese by fat cells. In cases of lipodystrophy and defects of adipogenesis lipoid accumulates ectopically in the liver, skeletal muscle, pancreas and cardiovascular tissues and impairs the function of th...

Background: Hypothalamic hamartomas(HH)-rare heterotopic congenital malformations (incidence 1:200 000)-present with central precocious puberty (CPP) or gelastic seizures (GS) but their natural history and best treatment strategy are unknown. Given their proximity to the hypothalamus–pituitary axis, wider endocrine dysfunction may be expected.Objective and hypotheses: To describe clinical features and any evolving endocrinopathies in HH patients, by...

Background: Hypogonadotropic hypogonadism is characterised by inadequate secretion of gonadotropins (luteinising hormone (LH) and follicle-stimulating hormone (FSH)) leading to absent, partial or arrested puberty. In males, classical treatment with testosterone promotes virilisation but does not facilitate testicular growth and spermatogenesis. Conversely, treatment with gonadotropins or gonadotropin-releasing hormone (GnRH) stimulates Sertoli and Leydig cells...

Background: Microtubules, polar polymers of αβ-tubulin heterodimers, constitute dynamic cytoskeletal structures implicated in the regulation of axonal activity along with neuronal proliferation and migration. Tubulinopathies, caused by pathogenic variants in genes encoding different isotypes of tubulin, lead to a wide and overlapping range of nervous system malformations and neurodevelopmental disorders. Namely, heterozygous missense and nonsense mu...

Keywords: COVID 19, height trajectory, rGHBackground: Various factors can interfere with height and body mass index (BMI) trajectories and therefore, auxological parameters reflect children’s health status. The COVID-19 pandemic has had an important impact on all the social determinants of health.Aim: The aim of the current study was to assess the effect of recombinant growth...

Background: While research demonstrated successful weight and BMI reduction in response to recent obesity drugs in adults and adolescents, there are significant limitations of current drugs targeting single receptors, such as problems maintaining a reduced weight status, and the high rates of gastrointestinal adverse events, which can lead to discontinuation of treatment. Based on this, we hypothesized that a more effective and better tolerated obesity interve...

Background and Objectives: Being born small for gestational age (SGA) as well as growth hormone (GH) treatment are associated with a disturbed glucose-insulin metabolism. We aimed to investigate whether SGA patients have a higher risk of developing an impaired glucose-insulin metabolism under GH treatment in comparison to children with an isolated growth-hormone deficiency (iGHD), to children with obesity and a healthy control group.<str...

Background: We have identified a novel tandem duplication leading to ubiquitous expression of the agouti-signaling protein (ASIP) in a female patient with severe early onset obesity, red hair, tall stature, and insulin resistance (Kempf, E. et al, 2022). Due to the ectopic expression, ASIP - which normally is only expressed in the skin - can interact with the Melanocortin-4-Receptor receptor in the hypothalamus thereby causing the obesity phenotype.<p clas...
