Fecal Microbiota Transplantation (FMT) in Multiple Sclerosis

A subject (n-of-1) clinically diagnosed with Relapsing Remitting Multiple Sclerosis (RRMS), by Rush University Neurologists, volunteered and provided written informed consent to participate in this study conducted by Rush University Medical Center's department of Digestive Diseases and Nutrition. The RRMS subject underwent a fecal microbiota transplantation (FMT) administered outside the United States, at Taymount Clinic in the Bahamas, for the treatment of their MS. Being one of the investigators' patients, the subject volunteered to donate their stool samples to the Rush University Medical Center Gastrointestinal (GI) tissue repository for microbiota interrogation at the following time points: before FMT (baseline), 3, 13, 26, 39, 52 weeks (1 year) after FMT, to determine the impact on their microbiota composition and sustainability of the change. The subject also agreed to donate their blood during the above stated time points to see if FMT affected markers of bacteria translocation and systemic inflammation. The subject also agreed to have their GI symptoms, diet, sleep, and MS related symptoms (rating scales or questionnaires), MRI (brain \& spine), as well as their gait metric activity objectively assessed to see if the FMT affects these symptoms and whether any observed improvement is sustained, in this proof-of-concept study. Based on this research, the investigators hypothesize that the FMT will significantly altered the overall microbial community structure to promote the growth of short chain fatty acid (SCFA)-producing beneficial bacteria, which in turn could potentially improve the MS subject's health outcomes, neurological symptoms, and walking metrics over time. More clinical trials (larger sample size) will be needed to study the potential of FMT for the treatment of MS and to examine the long term effects. FMT is an emerging treatment approach for MS. The donor selection, the separation of fecal bacteria, the frequency of FMT, the way of infusion, the long-term safety, and efficacy are still uncertain and need to be examined.
