Faecal microbiota transplant in Parkinson’s disease: pilot study to establish safety & tolerability
Bibliographic record
Abstract
Emerging evidence suggests gut microbiota differences in Parkinson's Disease (PD) may impact disease progression and treatment. Faecal Microbiota Transplantation (FMT) offers a potential therapeutic approach. We conducted an open-label pilot study to assess the safety, tolerability, and symptom impact of FMT in 12 patients with mild to moderate PD, administered via enema for 6 months. FMT was safe and well tolerated, causing only mild, transient gastrointestinal symptoms. While no significant motor symptom changes were observed, there was a trend toward reduced daily OFF time at 2 months. Whilst no sustained improvement in non-motor symptoms was found after 6 months, transient improvements in quality of life and non-motor scores were noted at 2 months; these gains regressed by study end. Overall, extended FMT therapy in PD appears safe and tolerable, with reduction in daily motor OFF time and self-reported non-motor symptoms that was not sustained throughout the 6-months of treatment.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
