Background: Heterozygous pathogenic variants in the ACAN gene underlie disproportionate short stature with characteristically accelerated bone age (BA) maturation and/or osteochondritis dissecans (OD)/early-onset osteoarthritis (OA).Objective: To describe the phenotypic spectrum and assess the response and safety of growth hormone (GH) treatment in children with a heterozygous pathogenic ACAN variant.</...

Introduction: Patients carrying homozygous IGF1 loss-of-function mutations are extremely rare and show severe pre- and postnatal growth failure, microcephaly, developmental delay, retrognathia and sensorineural deafness. Heterozygous variants in IGF1 appear to be more common in short stature, but only few cases have been reported in detail. Therefore, clinical features and growth response to recombinant human growth hormone (rhGH) therapy are...

Background: Constitutional delay of growth and puberty (CDGP) is one of the most frequent norm variants in children presenting with short stature. Knowing the height, growth, and weight pattern of CDGP in the first years of life is important to distinguish CDGP from growth hormone deficiency (GHD) or other diseases.Methods: We studied height and weight in the first 5 years of life in 54 boys with CDGP including measureme...

Background: For children with retarded bone ages such as in constitutional delay of growth and puberty (CDGP) there are no specific methods to predict adult height based on bone age. Widely used methods such as Bayley-Pinneau (BP) tend to overestimate adult height in CDGP. Therefore, we aimed to develop a specific adult height prediction model for boys in pubertal age with retarded bone age >1 year.Methods</...

Background: Restarting rhGH treatment in adolescents with childhood-onset GH deficiency (CO-GHD) is usually based on the GH re-test, IGF-1, additional pituitary hormone deficiencies and pituitary gland morphology, but not on body composition. Short-term changes of body composition in adolescents with CO-GHD when off rhGH may contribute to the identification of those in need of continuation of treatment.Study design: In this prospective single-centre stud...

Background: Recently we described a family with several members having intrauterine and postnatal growth failure as well as signs of Silver–Russell syndrome (SRS) who carried a heterozygote nonsense mutation of IGF2. The patients had low IGF-II serum levels, but normal IGF-I serum levels.Objective and hypotheses: We aimed to estimate the diagnostic value of the IGF-II, IGF-I and IGFBP-3 measurements in the assessment of children with SRS.<p clas...

Background: There is no knowledge of the energy metabolism in the presence of X chromosome aneuploidy or structural aberrations. Recently, an abnormal muscle metabolism was observed in girls with Turner syndrome (TS).Objective and Hypotheses: Resting energy expenditure was prospectively estimated by indirect spirometry in 92 short prepubertal girls at the start of GH therapy.Method: The diagnoses were TS (n=23), GH deficie...

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...

Background: Copeptin is secreted in isomolar amounts along with arginine vasopressin peptide from the posterior pituitary. Its stability makes it a perfect candidate for the endocrine approach in the diagnosis of AVP deficiency. Arginine-stimulated copeptin is a possible alternative for the water deprivation test. We wondered whether basal and stimulated copeptin secretion is related to growth hormone secretion status or independent of it.<p class="abstext...

Background and Aim: Several genetic variants associating with hepatic fat content in adults have been identified in genome-wide association studies. Their effects in children remain unclear. This study aimed to test the effect of genetic variants known to associate with hepatic fat in adults, individually and combined as a genetic risk score (GRS), on cardiometabolic traits, and to investigate the predictive ability of the GRS for hepatic steatosis in children...
