AIM: Indoles are tryptophan (Trp)-derived metabolites that are produced by the gut microbiota and may influence the gut-microbiota-brain axis in multiple sclerosis (MS). Indole-3-lactate (ILA) is reduced in persons with MS and improves MS clinical scores in animal models via its anti-inflammatory remyelinating properties. The ILA/indole-3-acetate (IAA) (ILA/AA) index is considered a neuroprotection index. Physical exercise and diet can modify gut microbiota and indole metabolism.
METHODS: This secondary analysis of a randomized control trial aimed to assess the effects of acute and chronic exercise on serum indoles in relapsing-remitting MS (RRMS). Thirty-one RRMS patients (≥ 70% session attendance) completed a 10 week multimodal functional training (60 min, 3×/week) vs. a waitlist control group. Blood samples were collected at baseline and compared to a matched healthy control group, and after 10 weeks for the assessment of chronic effects. Additionally, acute effects of a single bout of exercise were assessed with a blood sample before, during, and immediately after one interim training session. Serum indole concentrations were measured using LC-MS/MS.
RESULTS: Baseline indole levels in RRMS patients differed from those of matched healthy controls, and reduced ILA levels were observed. The 10 week intervention increased the ILA/IAA index, while a single exercise bout induced an increase in both ILA and ILA/IAA.
CONCLUSION: Multimodal functional training over 10 weeks led to an improved ILA/IAA index suggesting a neuroprotective shift in gut microbiota composition, and a single bout acutely increases the circulating level of ILA.
