Abstract
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 and Methods
Seventy-one patients were enrolled between 1988 and 1999. The originally planned sample size was 80 subjects, which provided 80% power, after allowing for dropouts, to detect a 3-cm difference in mean adult height between the two treatment groups.
Results
Baseline patient characteristics are shown in Table 1. Among 68 randomized subjects who received the study drug, adult height measurements were available for 33 after mean treatment duration of 4.4 yr ( Table 1 ).
Discussion
This study, which demonstrates a positive GH effect on adult height of peripubertal children with idiopathic short stature, is unique in using a randomized, double-blind, placebo-controlled design to adult height.
Acknowledgements
We thank the subjects and their families. We also thank Drs. Michael Draper and John Holcombe for their assistance with the development of this protocol and Drs. Arthur Levine and Duane Alexander for their support during the study.
