The Efficacy of Low Dose Naltrexone Therapy in Children With Crohn's Disease

Summary

It is hypothesized that oral naltrexone will improve inflammation of the bowel by increasing endogenous enkephalin levels in subjects with active Crohn's disease. This is especially important in children who often are suffering from nutritional deprivation which retards their growth. The key objectives are to: 1. Evaluate the effects of low dose naltrexone in children with Crohn's Disease by using the Pediatric Crohn's Disease Activity Index (PCDAI), plasma inflammatory markers, weight, and pediatric quality of life survey. 2. To determine the safety and toxicity of low dose naltrexone in pediatric subjects with active Crohn's Disease. 3. Assess the potential mechanism by which naltrexone exerts its action by measuring plasma opioid (enkephalin and endorphin levels) and proinflammatory cytokines.
