Efficacy and safety of growth hormone treatment in children born small for gestational age in Japan.

Growth-promoting effects and safety of growth hormone (GH) treatment in prepubertal short-statured children born small for gestational age (SGA) were evaluated in a multicenter, open-label, randomized parallel-group comparison study. Patients were randomized to two dose groups; 34 and 33 patients received GH at 0.033 and 0.067 mg/kg/day for one year, respectively. The increase of the mean height velocity standard deviation score (SDS) was significantly (p <0.0001) higher in the 0.067-mg group (from -1.4 to 4.7) than that in the 0.033-mg group (-1.9 to 2.6). A significant (p <0.0001) increase in the mean height SDS was established in the 0.067-mg group; increases of -3.1 to -2.5 vs -3.1 to -2.2 in the 0.033- and 0.067-mg groups, respectively. The trial was non-eventful. Oral glucose tolerance tests indicated a mostly normal pattern of plasma glucose before and after 12-month GH treatment. The growth-promoting effect was significantly higher with GH treatment at 0.067 mg/kg/day.
