Immunotherapy-Mediated Modulation of the Gut Microbiota in Multiple Sclerosis: The Effects of High-Efficacy (Cladribine) and Moderate-Efficacy (Interferon Beta-1a) Treatments

microbes, among others, was associated with no evidence of disease activity (NEDA). Our results provide supporting evidence that alteration of the microbiota by DMTs is part of their beneficial effect, and while some modifications seem to be DMT-specific, MS-DMTs in general promote SCFA-producing microbes, which positively correlate with a favorable clinical outcome. Future therapeutic strategies for PwMS may benefit from microbiome modulation, contingent upon additional mechanistic and interventional studies.
