Gut–brain microbiota link in new‑onset and drug‑resistant epilepsy
Official title: MiCrobiota-gut-brain Axis in Resistant Epilepsy
Run by Niguarda Hospital · NCT07010445 · Data updated 2026-11-12
This project will see if gut bacteria and their chemical products are linked to how well people with new‑onset or drug‑resistant epilepsy do after surgery, vagus‑nerve stimulation, or a ketogenic diet.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are people aged 3–50 with a new diagnosis of epilepsy or drug‑resistant epilepsy who are willing to provide consent (or have a consenting caregiver) and can attend follow‑up visits, and who have not used antibiotics, corticosteroids, or probiotics in the prior month and do not follow special diets.
✕Probably not a fit
Patients with chronic organic gastrointestinal diseases, those on special diets, or those who recently used antibiotics, corticosteroids, or probiotics (within one month) — as well as people outside the 3–50 age range — are unlikely to benefit from participation.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This longitudinal study will enroll people with first‑time seizures and patients with drug‑resistant epilepsy who are undergoing resective surgery, vagus‑nerve stimulation (VNS), or ketogenic diet (KD), and will follow them for about 12 months with visits over ~15 months from screening to last follow‑up. Investigators will collect stool for gut microbiota and metabolic profiling alongside detailed clinical, biochemical, neurophysiological, neuroradiological, and genetic data at baseline (before antiseizure medications when possible) and multiple post‑treatment time points. The target enrollment is at least 50 subjects at seizure onset, 50 DRE undergoing surgery, 10 DRE receiving VNS, and 10 DRE on KD. Data analysis aims to identify microbial biomarkers that correlate with clinical outcomes after these different therapeutic procedures.
Why it matters
Potential benefit: If successful, the results could identify gut microbiome biomarkers that help personalize treatments and improve seizure outcomes for people with epilepsy.
How similar studies have gone: Animal and human studies have linked the gut microbiome to epilepsy and shown microbiome changes with ketogenic diet, but using microbiome profiles to predict outcomes after surgery or VNS remains largely untested.
