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
FMT enemas were sourced from Biomebank, a Therapeutic Goods Administration (TGA)-accredited provider based in South Australia (ARTG #399066). The FMT donor screening, collection, and manufacturing followed the standards outlined in Therapeutic Goods Order No. 105 – Standards for FMT18. The FMT was administered by a clinical nurse as a 50 mL enema containing 12.5 g of donor faeces. Subjects were instructed to retain the FMT for at least 30 min in the right lateral position. The intervention consisted of an induction phase with 6 donor FMT enemas over 8 weeks (weeks 0, 1, 2, 3, 5, 7), followed by a maintenance phase with 4 monthly donor FMT enemas over 4 months (months 3, 4, 5, 6), totalling 6 months of FMT therapy.
More evidence that GMP stool banks are not valid approaches to FMT.
