【摘要】Objective. To study the value of serum insulin-like growth factor binding protein-3 (IGFBP-3) levels in differential diagnosis of growth hormone deficiency (GHD). Methods. To measure serum IGFBP-3 levels by RIA in normal children and adolescents, GHD children and short-stature children without GHD. Results. Serum level of IGFBP-3 in 129 children with untreated GHD and with no pubertal development was 1.6± 0.9 mg/L, which was less than that in normal group of the same age, but overlapped with the normal children in Tanner stage I. After six -month treatment with recombinant human growth hormone (rhGH), serum level of IGFBP-3 in 59 GHD significantly increased from 1.3± 0.7 mg/L to 2.7± 0.9 mg/L, accompanied by an increase of body heights, growth velocities and serum level of IGF-1. Serum level of IGFBP-3 in 55 short-stature children without GHD was 3.3± 2.2 mg/L, which was not significantly different from that in normal group. Conclusion. Serum IGFBP-3 level can reflect the status of GH secretion in children with GHD
