Descriptive Information
Brief Title  ICMJE Effects of GH on Body Proportions and Final Height in X-Linked Hypophosphatemic Rickets
Official Title  ICMJE Effects of Growth Hormone Treatment on Body Proportions and Final Height Among Small Children With X-Linked Hypophosphatemic Rickets
Brief Summary X-linked hypophosphatemic rickets (XLH) is characterized by rickets, disproportionate short stature, impaired renal phosphate reabsorption and vitamin D metabolism. Despite oral phosphate and vitamin D treatment, most children with XLH demonstrate reduced adult height. The main objective of the study is to determine the beneficial effects of recombinant human growth hormone (rhGH) therapy on body proportions after 36 month in these patients. Secondary objective is to monitor side effects of the therapy.
