简要总结
Crohn's disease is a chronic inflammatory disorder of the gastrointestinal tract. The origin of Crohn's disease remains unknown and there is no curative therapy, either medical or surgical, for this gut disorder.
It is believed that an infectious agent is important in the development of Crohn's disease. The similarity of Crohn's disease to the animal form of ileitis, termed Johne's disease, supports the possibility that both disorders are caused by exposure to Mycobacterium avium paratuberculosis or MAP. Multiple investigators have demonstrated good clinical responses of patients with Crohn's disease to treatment with triple antibiotic therapy directed against mycobacterial infection.
The hypothesis of this protocol is that triple antibiotic therapy is useful as a medical therapy for patients with Crohn's disease. The aim of this study is to examine the response of patients with Crohn's disease who are not receiving therapy with biological agents to triple antibiotic therapy.
详细描述
Clinical remission will be determined by a decline in the Crohns disease activity index to <151; clinical improvement will be examined using the inflammatory bowel disease (IBD) quality of life questionnaire; and endoscopic improvement will be examined using a Crohn's disease endoscopic activity index. All individuals must have had colonoscopy within 3 months of enrollment. An estimated 20 individuals will be enrolled in this protocol. Each patient will be treated for 6 months with a combination of rifabutin, clarithromycin, and clofazimine. At the end of 6 months of treatment for each patient, the Crohns disease activity index will be recalculated, each patient will again complete the IBD quality of life questionnaire, and each patient will undergo repeat colonoscopy.
