Alteration of Gut Microbiota in Patients With Epilepsy and the Potential Index as a Biomarker

OBJECTIVE: To explore the structure and composition of the fecal microbiota of patients with epilepsy. METHODS: = 10 HCs)]. Analysis of gut microbiome indicated predictive ability for disease diagnosis, with an area under the receiver operating characteristic (ROC) curve (AUC) of 0.97 (95% CI, 0.84-0.98). Applying the model to our validation cohort resulted in an AUC of 0.96 (95% CI, 0.75-0.97). Notably, the model could distinguish drug-resistant from drug-sensitive epilepsy (AUC = 0.85, 95% CI: 0.69-0.94). CONCLUSION: Patients with epilepsy exhibit substantial alterations of fecal microbiota composition, and specific gut commensal strains are altered depending on different clinical phenotypes and thus could serve as potential biomarkers for disease diagnosis.
