The gut microbiota plays a role in the development of the immune system and can affect the risk for immune-mediated disorders like multiple sclerosis (MS). This study shows that treatment with dimethyl fumarate (DMF) leads to changes in gut microbiota composition and identifies specific microorganisms associated with side effects of DMF. These findings suggest that targeting the gut microbiota could improve disease course and tolerance to DMF.
The gut microbiota is involved in the development of the immune system and can modulate the risk for immune-mediated disorders such as multiple sclerosis (MS). Dysbiosis has been demonstrated in MS patients and its restoration by disease-modifying treatments (DMTs) is hypothesized. We aimed to study the changes in gut microbiota composition during the first 6 months of treatment with dimethyl fumarate (DMF), an oral DMT, and to identify the microorganisms associated with DMF side effects. We collected and analyzed the gut microbiota of 19 MS patients at baseline and after 1, 3, and 6 months of DMF treatment. We then cross-sectionally compared gut microbiota composition according to the presence of gastrointestinal (GI) symptoms and flushing. Overall, the gut microbiota biodiversity showed no changes over the 6-month follow-up. At the genus level, DMF was associated with decreased Clostridium abundance after 6 months. In subjects reporting side effects, a higher abundance of Streptococcus, Haemophilus, Clostridium, Lachnospira, Blautia, Subdoligranulum, and Tenericutes and lower of Bacteroidetes, Barnesiella, Odoribacter, Akkermansia, and some Proteobacteria families were detected. Our results suggest that gut microbiota may be involved in therapeutic action and side effects of DMF, representing a potential target for improving disease course and DMT tolerability.
