Long-term effects of growth hormone treatment on height in Turner syndrome: results of a 6-year multicentre study in Japan. Committee for the Treatment of Turner Syndrome.
Patients with Turner syndrome have many somatic characteristics, including short stature. We report the results of a 6-year multicentre clinical trial of recombinant human growth hormone (GH) therapy in 63 patients with Turner syndrome. Twenty-six patients received GH at a dose of 0.5 IU/kg/week, while 37 received GH, 1.0 IU/kg/week, by daily subcutaneous injection. At the start of GH treatment, there was no significant difference between the two groups in chronological age, bone age, height or growth rate. Both treatment groups showed a significant growth increase during treatment. The current mean height of the 12 patients over the age of 16 treated with GH, 0.5 IU/kg/week, is 145.1 +/- 4.7 cm, and in the 16 patients treated with GH, 1.0 IU/kg/week, is 144.0 +/- 2.2 cm. In conclusion, treatment with GH does increase final height in patients with Turner syndrome. However, further studies are needed to determine the optimum age for the initiation of GH therapy, the best dose regimen and the optimal time and manner of sex and anabolic steroid use.
