Background:
TNFalpha-antibodies have been used increasingly in treatment of inflammatory bowel disease (IBD) during the last years. This article provides an overview of indications, contraindications, efficacy, and side effects of this so-called biological treatment of IBD.
Material And Methods:
Based on the clinical experience of the authors, literature was selected through a non-systematic search in PubMed.
Results:
TNFalpha-antibodies have a documented initial effect in 60-70 % of patients with moderate to severe luminal and/or fistulising IBD. Approximately 30 % of patients achieve remission after a relatively short treatment period. However, the effect seems to decrease during long-term treatment. It is still unsettled whether these drugs prevent colectomy in ulcerative colitis. The treatment seems to increase the risk of serious infections and there are also some indications of an increased risk of malignancy. Combination therapy with azathioprin is common and probably increases both the effect and the risk of side effects.
Interpretation:
TNFalpha-antibodies have become an important part of the treatment for moderate to severe IBD, but the effect decreases during long-term treatment and has to be evaluated in light of potential side effects. Further long-term studies are necessary.
