It is common knowledge that the administration by mouth of chlorhydrate arginine in children with BSC is followed by an increase of plasma levels of Growth Hormone and Insulin as well as an improvement of statural growth. In order to confirm or disprove this observation we have administrated chlorhydrate arginine for six months in children affected by BSC. We have treated 20 prepubertal children (14 males, 6 females) affected by BSC (13 constitutional growth delay, and 7 familiar short stature) with chronological age ranged from 4.75 to 12.55 years, and bone age from 3 to 12 years, with height < 10 degrees centile. The chlorhydrate arginine was administered by mouth at a daily dosage of 4 g (1 phial/2) for 6 months. Height was controlled 6 months before treatment ("off" period) at the start, and after 6 months of treatment ("on" period). Before the start of treatment GH release was assessed with 3 pharmacological tests (arginine, insulin and clonidine) at last of treatment has been made only arginine test in order to investigate GH and insulin response. We have compared the "off" with "on" period and we have observed a substantial improvement (p < 0.01) of the height velocity (HC), worded in SDS-HC (standard deviation score of height velocity) that changed from -1.21 +/- 0.40 to -0.30 +/- 1.37 with a positive difference of +0.91 +/- 0.47 between the two periods. As for as GH release is concerned we have observed, after therapy, a significant increase of mean almost twice that see in the "off" period and the difference is significant p = 0.012).
