title: Comparison of growth hormone treatment in patients with idiopathic short stature and idiopathic growth hormone deficiency.
abstract: After recombinant human growth hormone (rhGH) was introduced in the treatment of patients with growth hormone deficiency (GHD) and idiopathic short stature (ISS), many studies have addressed the effect of GH treatment and changes in the height standard deviation score (SDS) after GH treatment. However, few studies comparing the effect of GH in Korean patients with idiopathic GHD and ISS have been designed. Therefore, this study focused on the difference in effect of GH treatment between the two groups. We retrospectively reviewed the height SDS of 34 patients with idiopathic GHD and 12 patients with ISS. The mean ages of the patients with idiopathic GHD and ISS were 9.84±2.09 and 10.72±1.48 years, respectively. All patients were treated with GH for 1 year and body parameters were recorded before and after the GH treatment. Change in height SDS in patients with idiopathic GHD was significantly higher than that in patients with ISS (0.62±0.33 vs. 0.40±0.27, p=0.03). However, body mass index, insulin-like growth factor-1, and insulin-like growth factor binding protein-3 were not significantly different between the two groups after GH treatment. These results suggest that GH treatment has a more powerful effect on increasing height SDS in patients with idiopathic GHD than in patients with ISS.
