Key clinical point: Gut microbiota may have a potential casual association with migraine symptoms, with evidence indicating a connection between gut microbiota and increased or decreased risk for migraine.
Major finding: A higher abundance of genus Lactobacillus (inverse variance weighted [IVW] odds ratio [OR] 1.10; P = .004) and family Prevotellaceae (IVW OR 0.89; P = .02) were causally associated with a higher and lower risk for migraine, respectively.
Study details: This study used a two-sample Mendelian randomization framework to assess the causal effects of gut microbiota on migraine risk using 2651 single nucleotide polymorphisms as instrumental variables. Large-scale genome-wide association studies consisting of 18,340 participants from 24 cohorts provided the summary-level statistics for gut microbiota.
Disclosures: This study was funded by the National Key Research and Development Program. The authors declared no conflicts of interest.
