About this trial
The overall goal of this study is to elucidate a mechanism by which vancomycin modulates the gut-brain axis in multiple sclerosis (MS). The gut microbiome plays an important role in autoimmunity, including MS. However, the identity of gut microbes modulating neuroinflammation in MS and their mechanisms of action remain obscure. Hence, here the research team proposes to investigate the effects of vancomycin on the gut microbiota composition, peripheral immune function, and brain MRI lesions in MS patients.

Treatment groups
Trial outcomes
Primary outcomes
Changes in abundance of butyrate producing bacteria
Changes in abundance of butyrate producing bacteria from baseline treatment up to 6 weeks
Changes in Serum Butyrate levels
Changes in serum butyrate level from baseline treatment up to 6 weeks Butyrate is a substance that is produce when gut bacteria breaks down food. Butyrate can get into our blood circulation and regulate how our immune cells function.
Changes in number of peripheral T cells
Change in frequency of peripheral regulatory T cells baseline treatment up to 6 weeks. T cells are a type of lymphocyte. Lymphocytes are a type of white blood cell. They make up part of the immune system. T cells help the body fight diseases or harmful substances, such as bacteria or viruses.
Secondary outcomes
Changes in abundance of short chain fatty acids (SCFAs)-producing bacteria
Changes in abundance of SCFA-producing bacteria
Change in stool SCFAs levels
Change in stool SCFAs levels SCFAs are substance that are produce when gut bacteria breaks down food.
Change in serum SCFAs levels
Change in serum SCFAs levels
Change in number of gadolium enhancing brain lesions
Change in number gadolium enhancing brain lesions A lesion is a brain injury caused by inflammation. Gadolinium is a dye that is used to visualize areas of active inflammation in the brain.
