Abstract
Inflammatory bowel disease (IBD) like Crohn's disease and ulcerative colitis are chronic inflammatory disorders that affect the bowel. The disease is characterized by periods of clinical remission and relapse due to severe intestinal inflammation. Drug therapy of IBD is associated with unpleasant side effects. Further, efficacies of conventional drugs decrease with chronic use and this can represent a major difficulty in the long term management of IBD. However, in active IBD, leukocytes are elevated in the lesion they may be able to be a factor of IBD aggravation. Membrane filters column and leukocyte adsorbing beads have been developed which are direct blood perfusion systems for removing any desired level of leukocytes. Clinical studies with these two new models have shown good effects for active IBD. Clinical data suggest that leukocytapheresis might be an effective adjunct to therapy of IBD, to promote remission, taper conventional drug dosage and potentially should reduce the number of patients who require colectomy. The results may further understandings of the pathophysiology of IBD and this in turn should contribute to a more effective treatment of this disorder.
