Defective growth hormone secretion in children with pycnodysostosis and improved linear growth after growth hormone treatment.
Abstract
Short stature is a characteristic feature of pycnodysostosis. We report defective growth hormone secretion in response to provocation and low insulin-like growth factor-I (IGF-I) concentration in five out of six patients with pycnodysostosis. Physiological replacement with growth hormone increased IGF-I concentration and improved linear growth in these children.
