title: Specific mediator-directed therapy for gastrointestinal diseases.
abstract: A number of inflammatory mediators--such as proinflammatory cytokines, lipid derived eicosanoids and reactive oxygen metabolites--are elevated in chronic bowel inflammation. Existing drugs for Crohn's disease and ulcerative colitis, for example aminosalicylates and corticosteroids, work at many sites in the inflammatory cascade to control disease activity. These drugs may be associated with significant side-effects and do not always control the disease. Therefore there is an impetus to develop treatments which are safer and more specific for bowel inflammation. Specific inhibitors of inflammatory mediators have recently become available and some have been shown to be effective in animal models of bowel inflammation. Although far fewer data are currently available on specific mediator-directed therapy of intestinal inflammation in humans, early clinical trials in inflammatory bowel disease have given mixed results. It remains to be determined whether or not this strategy of specific mediator inhibition is an alternative to current therapy for chronic bowel inflammation in humans.
