Abstract
BACKGROUND: Multiple sclerosis is associated with gut microbiome alterations. The current study aimed to investigate the effect of home-based exercise on gut bacteria in people with multiple sclerosis (MS). We also examined the association of exercise-induced gut bacterial modulation with circulating levels of inflammatory and anti-inflammatory cytokines.
MATERIALS AND METHODS: Forty-two people with MS (female/male: 31/11, expanded disability scale status <5) participated in this study and were divided into two groups: 6 months of home-based exercise (5 sessions per week) and controls. Before and after the intervention, the following parameters were assessed: gut microbiota, including faecalibacterium prausnitzii, akkermansia muciniphila, prevotella and bacteroides counts; cytokine levels including interleukin (IL)-10 and tumor necrosis factor-alpha (TNF-α); and psychosocial factors including anxiety, depression, and fatigue.
RESULTS: Home-based exercise significantly increased prevotella counts, and decreased akkermansia muciniphila counts (p < 0.05); however, there were no significant effects on faecalibacterium prausnitzii and bacteroides counts (p > 0.05). There were no significant effects of home-based exercise on circulating cytokine levels (p > 0.05). Moreover, home-based exercise was associated with significant improvements in anxiety and depression (p < 0.05); however, fatigue revealed no significant change (p > 0.05). Akkermansia muciniphila, prevotella and bacteroides count changes in response to the intervention were correlated with changes in IL-10 (r = -0.052, r = 0.67, and r = -0.55, respectively).
CONCLUSION: In general, our data revealed the effect of exercise on gut bacteria, especially prevotella, and akkermansia muciniphila counts, which can probably have a beneficial effect on MS disease pathology and course; however, the lack of changes in cytokines following exercise suggests the possible role of mechanisms other than modulation of circulating IL-10 and TNF- α levels.
