Effect of 6 months of growth hormone treatment in young children with Prader—Willi syndrome

Abstract

Nine prepubertal children with Prader-Willi syndrome were treated with growth hormone (GH; 24 IU/m2/week) for 6 months. Mean height increased by 0.8 SD and mean weight for height decreased by 0.7 SD over this 6-month treatment period. Body fat, measured by dual-energy X-ray absorptiometry, decreased by 22.5% over the period of GH treatment, whereas fat-free mass increased by 14%. These preliminary results indicate that GH is effective in increasing height and normalizing body composition in patients with Prader-Willi syndrome.
