| Study objectives | Growth failure occurs in approximately one third of children with Crohn's disease. Insulin-like growth factor-I (IGF-I) concentrations are depressed in active Crohn's disease, and increase to normal on entering remission with enteral feeding. Growth Hormone concentrations are normal in active disease. The children therefore exhibit a resistance to growth hormones effects. A proportion of children do not enter remission despite state-of-the-art medications, and some of them continue to fail to grow. Treatment for the growth deficiency caused by low IGF-I activity would offer great benefits in such children. The treatment for endocrine causes of growth hormone resistance (usually due to growth hormone receptor defects) is subcutaneous IGF-I. Furthermore, injections of human IGF have been shown, in work published from our laboratory, to enhance growth in rats with colitis. An IGF-I preparation is now available to treat children with growth hormone receptor defects, but not other conditions. A detailed understanding of the pharmacokinetics of IGF-I is needed before IGF-I can be considered as a treatment for growth faltering in children with Crohns disease. We hypothesized that subcutaneous IGF-I will increase IGF-I concentrations of children with Crohn's disease associated with low IGF-I, without serious adverse effects. To examine this hypothesis we proposed to study three specific aims: 1. To examine the effect of IGF-I on IGF-I and glucose concentrations in the circulation over 24 hours after administration in children with Crohn's disease 2. To examine the effect of daily IGF-I on IGF-I over the course of 1 week 3. To examine the pharmacokinetics of IGF-I in children with documented protein losing enteropathy |
