The Effect of Therapeutic Fecal Transplant on the Gut Microbiome in Children With Ulcerative Colitis

Children's Hospital Los Angeles101 enrolled

Overview

Ninety Six patients with mild to moderate ulcerative colitis will be randomized to double blind, placebo controlled study. The safety and efficacy of the intervention will be closely monitored.

The enteric microbiota is now accepted as an important etiologic factor in the pathogenesis of human Inflammatory Bowel Disease (IBD) and immune-mediated chronic experimental intestinal inflammation, with ample data to implicate the microbiome as a main factor in the occurrence of IBD. This can be inferred from animals in germ-free environment which can protect from experimental colitis. In addition, increased gut permeability due to dysbiosis, is frequently seen in patients with IBD even in remission and, similarly, first degree relatives of IBD. Therefore, it is not surprising that therapeutic interventions aiming at modifying the gut microbiome would be of therapeutic benefit. Ulcerative colitis is a condition that is characterized by chronic inflammation of the colon. It is an important pediatric disease as 25% of all cases begin in childhood and its incidence is continuously on the rise. It is believed to be related to a genetically and environmentally-generated altered immune response to the enteric microbiome. Previous work in the PI's laboratory suggests that children harbor a unique gut microbial profile, which can predict therapeutic response. Therefore, modifying the gut microbiome may result in therapeutic benefit. However, attempts to modify the gut microbiome were largely unsuccessful until the advent of fecal transplant, which is a new approach in treating colitis. Fecal microbiota transplant (FMT) has been introduced several decades ago in an attempt to restore the gut microbial balance and it appears to be a more efficient method to effectively change and sustain the gut microbial composition. To date there have been a number of successful reports to suggest control of disease activity and in some cases cure of the disease. This study aims to further determine the safety and efficacy of FMT in treating children with ulcerative colitis

Outcomes

Primary Outcomes

The primary endpoint is disease remission based on PUCAI scores (<10).

The primary outcome including results of disease activity, and safety measures.

Time frame: 12 Months

Secondary Outcomes

Secondary endpoints will include change in mucosal inflammation reflected on laboratory studies.

Secondary endpoints include changes in gut microbial diversity - determined by gut microbial genomics and proteomics, and outcome measures for mucosal inflammation and repair including laboratory testing such as the level for C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) as well as the stool calprotectin level.

Time frame: 12 Months
