The Basis for Optimising Growth with Growth Hormone Usage in Children with Idiopathic Short Stature: Analysis of Data from KIGS (Pfizer International Growth Study Database)

Many children with idiopathic short stature (ISS) remain short as adults. Height can be improved permanently by growth hormone (GH) treatment, as in children with Turner syndrome or born small for gestational age. Although GH treatment for ISS is an approved indication in the United States, there is ongoing controversy in Europe about approving GH treatment for this indication as well as determining the optimal mode of treatment. In addition to data from randomized controlled trials, data from pharmacoepidemiological surveys such as the Pfizer International Growth Study Database (KIGS) have provided substantial information about the short-term and long-term effects of GH on growth and adult height in children with ISS. Based on published articles and a recent survey from KIGS on 454 patients who have reached adult height, we attempted to categorize those children with ISS who have the greatest chances of achieving a normal adult height, or at least gain the most height following GH treatment. This analysis provides a rational basis for discussion about the most efficacious and cost-effective uses of GH treatment in children with ISS. Copyright (C) 2011 S. Karger AG, Basel
