Purpose: This study aims to investigate the effect of gonadotropin-releasing hormone agonist (GnRHa) on the growth hormone (GH)-insulin-like growth factor-1 (IGF-1) axis and to evaluate whether -202 A/C IGF binding protein-3 (IGFBP-3) promoter polymorphism affects growth velocity in females with central precocious puberty (CPP) during treatment. Methods: Data was collected from 97 females younger than 9 years, diagnosed with precocious puberty and treated with GnRHa for at least 1 year at Kangdong Sacred Heart Hospital from 2014 to 2015. Their body height, weight, change in height standard deviation score (ΔSDS), serum IGF-1, serum IGFBP-3, bone age, and -202 A/C IGFBP-3 promoter polymorphism were measured before and after GnRHa treatment. The interrelationships between the variables were calculated. Results: During treatment, height SDS, IGF-1 SDS, IGFBP-3 SDS, and IGF-1/IGFBP-3 ratio significantly decreased. A significant correlation was observed between ΔIGF-1 SDS and Δheight SDS (r=0.405, P<0.001). The presence of the C allele was significantly correlated with IGF-1 SDS after treatment (P=0.049) and with IGFBP-3 SDS before and after treatment (P=0.012 and P=0.001), but not with ΔIGF-1 SDS, ΔIGFBP-3 SDS, ΔIGF-1/IGFBP-3 ratio, or Δheight SDS. Conclusion: Growth velocity during GnRHa treatment is related to ΔIGF-1 SDS, indicating the apparent impact of GnRHa on the GH-IGF-1 axis. The -202 A/C IGFBP-3 promoter polymorphism does not affect the growth velocity of GnRHa in CPP girls.
