Changes in IGF-I, IGFBP-3 and ghrelin levels after adenotonsillectomy in children with sleep disordered breathing
Özet
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). Conclusion: 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.
