Final Height in Growth Hormone Deficient Children Treated with Growth Hormone.
Byung Churl Lee, Soon Ju Lee, Min Ho Jung
Abstract
PURPOSE
Improved adult final height(FH) is a major goal in the treatment of children with short stature due to growth hormone deficiency(GHD). The purpose of this study was to evaluate final height in idiopathic and organic GHD children after long-term growth hormone(GH) treatment. METHODS:Twenty five(16 males and 9 females) patients with GHD(14 idiopathic and 11 organic GHD) were included. GHD was diagnosed by two or more GH provocation tests(peak GH level <10 ng/mL). All subjects had multiple pituitary hormone deficiencies, and aged 10.7+/-.5(5.5-14) years at the start of GH treatment. The patients were treated with GH 0.45-0.7 IU/kg/week in 3-7 divided doses for 6.9+/-.8(5.2-10) years. Treatment was ended when growth velocity reached lower than 2 cm/year and/or bone age reached 16 years. Standard auxologic measurements were performed at the start of GH treatment and at every 6 month after initial GH treatment.
RESULTS
FH was 166.9+/-.8 cm, which was not significantly lower than target height(167.1+/-.9 cm) and predicted adult height(169.1+/-5 cm). FH SDS was significantly improved to -0.8+/-.5 compared with -3.4+/-.0 of height SDS at the start of GH treatment. The largest height increment was observed in the first year of GH treatment, with a gradual decrease in the following years. There was no difference in FH and FH SDS between idiopathic and organic GHD. Unwanted serious adverse events were not observed in all patients during GH therapy.
CONCLUSION
Early diagnosis and continuous treatment with optimal doses of GH to near adult height improve the outcome in children with short stature due to idiopathic and organic GHD.
