Abstract
Aims: To determine the effectiveness of different doses of r-hGH therapy during puberty in children with growth hormone deficiency (GHD). Methods: Randomized controlled trial of different doses of r-hGH therapy administered during puberty in 49 children with GHD. The patients were allocated randomly using a random number table to one of two groups: group 1 (15 IU/m2/week) or group 2 (30 IU/m2/week). Patients were included if they had received r-hGH daily at a dose of 15 IU/m2/week (0.7 mg/m2/day) for at least 1 year before randomization. Results: Height increase standard deviation scores (SDS) were similar between the two groups (group 1: 1.1; group 2: 1.2; p = 0.81). Conclusion: A higher dose of r-hGH administered during puberty does not appear to have a significant effect on final height of children with GH deficiency. Altering pubertal tempo or intensifying prepubertal r-hGH therapy may be a more promising approach to improving final height in children with GH deficiency.
