Safety of Growth Hormone Treatment of Children with Idiopathic Short Stature: The US Experience
Recombinant human growth hormone ( rhGH ) is approved in the United States for treatment of idiopathic short stature ( ISS ) . The occurrence of adverse events ( AEs ) and the long-term safety of rhGH treatment in this patient population are review ed . Data were analyzed from postmarketing surveillance studies that included ISS patients , prospect i ve ISS treatment trials and studies of specific AEs in smaller groups of rhGH-treated children . Frequency rates of targeted AEs ( i.e. , scoliosis , slipped capital femoral epiphysis , intracranial hypertension , pancreatitis ) in patients with ISS are similar to or lower than the rates observed in other rhGH-treated conditions . At dosages of 0.24–0.37 mg/kg/week , rhGH treatment in children with ISS does not adversely affect blood glucose levels . At dosages ≧0.3 mg/kg/week , a dose-dependent increase in mean fasting and stimulated insulin levels is observed . Current evidence derived from ‘ on-treatment ’ surveillance studies suggests that rhGH does not increase the risk for new malignancies in children with ISS.The  safety profile  of rhGH at doses ≤0.37 mg/kg/week for the treatment of children with ISS is similar to or better than the profile seen in other rhGH-treated conditions and is not associated with any predictable AEs . Due to a continuing trend toward dose escalation to achieve greater height-promoting effects and the possibility of delayed post-treatment effects of hyperinsulinemia and /or heightened GH and insulin-like growth factor I exposure on cancer risk , caution and ongoing scrutiny of risks versus benefits are warranted
