title: Changes in IGF-I, IGFBP-3 and ghrelin levels after adenotonsillectomy in children with sleep disordered breathing.
abstract: OBJECTIVE
  The aim of this study was to determine the changes in insulin-like growth factor-I (IGF-I), insulin-like growth factor binding protein-3 (IGFBP-3) and ghrelin levels following adenotonsillectomy (T&A) in children with sleep disordered breathing (SDB).
  
  
  METHODS
  Forty children (mean age 4.85+/-2.15 years) clinically diagnosed with adenotonsillar hypertrophy (ATH) related SDB were enrolled. All children underwent T&A. Serum levels of IGF-I, IGFBP-3 and ghrelin were measured before and 6 months after T&A.
  
  
  RESULTS
  Serum levels of IGF-I and IGFBP-3 were significantly higher after T&A (p<0.001). Serum ghrelin levels showed a significant decrease after T&A (p<0.001).
  
  
  CONCLUSIONS
  Children with ATH related SDB who underwent T&A showed significant increases in IGF-I and IGFBP-3 levels indicating an increase in diurnal growth hormone secretion as well as a significant decrese in ghrelin levels indicating an increased oral food intake in the postoperative period.
