Use of a Novel Diet (UC DIET) for Treatment of Mild to Moderate Active Pediatric Ulcerative Colitis


Brief description of study

The goal of the study is to evaluate strategies that target the microbiota for the treatment of Ulcerative Colitis , This study will involve a novel diet that the investigators developed , based on the hypothesis that UC involves dysbiosis , underutilzation of certain metabolic pathways and use of pathways that increase risk of inflammation . The investigators have postulated that manipulation of colonic bacterial metabolism with this diet will induce remission in UC without involving additional immune suppression.

Detailed Study Description

Ulcerative colitis is a chronic inflammatory disease primarily involving the colon. It has long been considered to be due to a dysregulated immune response targeting the colon, and involves unknown environmental factors . Recent studies have highlighted several characteristics which may suggest that UC is associated with alterations of the microbiota, defective production of short chain fatty acids and an impaired mucous layer. However at present, no effective therapy targets the microbiota or its interaction with the colonic epithelium. UC in humans is characterized by increased mucosal sulfides and increased sulfate and sulfide reducing bacteria and activation of amino acid metabolism pathways which impair butyrate production, whereas certain dietary patterns in humans and rodent models may induce dysbiosis and favor sulphide reducing bacteria. Further support for targeting the microbiota includes several studies demonstrating that antibiotics might be helpful for severe refractory colitis. Development of treatment strategies that target the microbiota could reduce exposure to immune suppression, and add new therapeutic strategies that do not exist at present.

Though diet has a significant impact on the composition of the microbiota no dietary intervention to date has proven effective for induction of remission. The investigators hypothesized that ulcerative colitis is caused by a series of events involving dysbiosis with sulfate or sulfide reducing bacteria combined with defective production of short chain fatty acids, coupled with a defective mucous layer.
