Sixty-eight children with non-endocrine short stature (NESS) were treated with recombinant human growth hormone (GH) for two years. The patients consisted of 20 children with familial short stature (FSS; Group A), 17 children with small-for-date short stature (SFD; Group B), 5 children with combined FSS and SFD (Group A+B), and 26 children with idiopathic short stature (ISS; Group C). GH treatment significantly increased height velocity, height SD score (SDS), and height velocity SDS for chronological age (CA) in NESS. The mean height velocity was increased by GH treatment from 4.4cm/year to 7.1cm/year in the first year and 6.3cm/year in the second year, the mean height SDS from -3.07 SD to -2.63 SD in the first year and to -2.42 SD in the second year, and the mean height velocity SDS for CA from -1.66 SD to 1.62 SD in the first year and to 0.66 SD in the second year. Among the four groups, there was no significant difference in the effect of GH treatment judged by height velocity or height velocity SDS for CA. However, the treatment tended to be less effective in group A+B. There was no significant difference among the four groups in the increase in height SDS.<BR>Seventeen children developed puberty during the two-year GH treatment: 7 in the first year and 10 in the second year. The mean height and age at the onset of puberty in 17 patients were 136.0 (±9.7) cm and 12.23 (±0.86) years in male, and 129.1 (±5.5) cm and 11.3 (±0.7) years in female patients, respectively. The height at the onset of puberty was shorter than that of normal children. Since it is known that children who develop puberty at short stature remain short, it is probable that the patients who developed puberty at short stature in this study will remain short as adults. The effect of treatment evaluated by the height SDS for BA was not improved. The effect of GH treatment in children with NESS should be carefully evaluated by conducting a long-term follow-up.
