Background: Children with Prader–Willi syndrome (PWS) attain high serum immunoreactive IGF1 levels during standard dose GH treatment, which leads to concern, but lowering the dose, deteriorates their body composition.Objective and hypotheses: To evaluate serum IGF1, IGFBP3 and acid-labile subunit (ALS) levels, complex formation and IGF-bioactivity in GH-treated PWS children. We hypothesized that GH-treated children with PWS have a normal IGF-bioacti...
