          Abstract

          Background/Aims: The effects of biosynthetic human growth hormone (r-hGH) in children with familial short stature (FSS) are varied. We determined whether responsivity to r-hGH in FSS is dose-dependent. Method: Randomised trial of two doses (20 or 40 IU/m<sup>2</sup> body surface area/week by daily subcutaneous injection) of r-hGH in 29 (24 male, 5 female) FSS children with assessment at adult height. Results: Age range at presentation was 5.1–10.5 years, height less than 1.5 standard deviation scores (SDS) below the mean, height velocity SDS greater than –1.5 and peak growth hormone response to provocative testing over 13.5 mU/l. Adult height data (SDS) at 16.5 ± 2.1 years for the low-dose group and 16.1 ± 1.1 years for the high-dose group (p = 0.62) were similar [low dose –1.06 (SD 0.75), high dose –1.02 (SD 0.83); p = 0.88]. The incremental effect of both doses on stature was minimal [low-dose difference in height actual-predicted 0.79 (SD 0.94), high dose 1.27 (SD 0.88); p = 0.12]. Conclusion: Using this r-hGH dosing schedule there were little short- or long-term effects on height in children with FSS.

            Effect of growth hormone treatment on adult height in peripubertal children with idiopathic short stature: a randomized, double-blind, placebo-controlled trial.

            GH is often used to treat children with idiopathic short stature despite the lack of definitive, long-term studies of efficacy. We performed a randomized, double-blind, placebo-controlled trial to determine the effect of GH on adult height in peripubertal children. Subjects (n = 68; 53 males and 15 females), 9-16 yr old, with marked, idiopathic short stature [height or predicted height < or = -2.5 sd score (SDS)] received either GH (0.074 mg/kg) or placebo sc three times per week until they were near adult height. At study termination, adult height measurements were available for 33 patients after mean treatment duration of 4.4 yr. Adult height was greater in the GH-treated group (-1.81 +/- 0.11 SDS, least squares mean +/- sem) than in the placebo-treated group (-2.32 +/- 0.17 SDS) by 0.51 SDS (3.7 cm; P < 0.02; 95% confidence interval, 0.10-0.92 SDS). A similar GH effect was demonstrated in terms of adult height SDS minus baseline height SDS and adult height SDS minus baseline predicted height SDS. Modified intent-to-treat analysis in 62 patients treated for at least 6 months indicated a similar GH effect on last observed height SDS (0.52 SDS; 3.8 cm; P < 0.001; 95% confidence interval, 0.22-0.82 SDS) and no important dropout bias. In conclusion, GH treatment increases adult height in peripubertal children with marked idiopathic short stature.

              Age at Growth Hormone Therapy Start and First-Year Responsiveness to Growth Hormone Are Major Determinants of Height Outcome in Idiopathic Short Stature

              Aim: To develop methods to identify factors associated with a favorable outcome in GH-treated children with idiopathic short stature (ISS). Methods: From 4,685 children listed as having ISS within KIGS (Pfizer International Growth Database), we studied (a) the prediction model group (n = 657) to develop the first-year prediction model, and (b) the near adult height group (NAH; n = 256) which received GH for >4 years to develop descriptive models for adult height and overall height gain. Results: NAH group at GH start: age was 10.0 years, height –2.5 SD score (SDS), weight –2.3 SDS, height minus mid-parental height (MPH) –1.5 SDS; GH dose 0.19 mg/kg/week. Height gain was 1.1 SDS at a median age of 17.2 years. Growth response correlated positively with GH dose and weight at the start of GH treatment, and negatively with age and height SDS minus MPH SDS. The model explains 39% (error SD 1.2 cm) of the variability. Adult height correlated (R 2 = 0.64) positively with height at GH start, MPH and the first-year responsiveness to GH, and negatively with age. Conclusions: Prepubertal children with ISS who show an appropriate first-year response to GH are likely to benefit from long-term treatment, even on low GH dosages.
