Abstract: A brand new scientific trial revealed fecal microbiota transplantation (FMT) as a possible new remedy for Parkinson’s illness (PD), displaying important enchancment in motor signs. The research explores the connection between the intestine microbiome and Parkinson’s, discovering that sufferers with PD typically exhibit altered intestine micro organism and elevated intestinal irritation.
By transplanting wholesome donor stool into sufferers with early-stage PD, researchers famous marked enhancements in motor features and reductions in constipation over 12 months, highlighting FMT’s promise for enhancing the standard of life for these with PD.
Key Info:
- The scientific research demonstrated that FMT considerably improved motor signs in Parkinson’s sufferers in comparison with a placebo group after one 12 months.
- This analysis underscores the rising hyperlink between the intestine microbiome and neurodegenerative ailments, suggesting that intestine micro organism play a vital position within the growth and symptomatology of PD.
- The research’s success opens the door for additional analysis into focused therapies, akin to growing a ‘bacterial capsule’ that might provide a much less invasive remedy possibility for PD sooner or later.

Parkinson’s illness (PD) is a standard neurodegenerative illness that impacts hundreds of thousands worldwide.
Now, a groundbreaking scientific research performed by researchers at Ghent College Hospital, VIB, and Ghent College has demonstrated the potential of fecal microbiota transplantation (FMT) to enhance signs in sufferers with PD.
This analysis, revealed in eClinicalMedicine, offers promising proof that FMT might be a precious new remedy for this debilitating dysfunction.
Parkinson’s illness is a neurodegenerative dysfunction that impacts hundreds of thousands worldwide. Its prevalence is quickly growing attributable to elements like pesticide use and an ageing inhabitants. Signs of the illness embrace each motoric and non-motoric signs.
The motoric signs, akin to stability issues, stiffness, and the attribute tremor, are the very best recognized and nearly at all times the explanation for the eventual analysis. Nevertheless, non-motor signs, akin to lack of scent, constipation, and REM sleep disturbances, typically develop as much as 20 years earlier than analysis in a lot of folks with the illness.
The position of the microbiome
In Parkinson’s illness, a protein known as alpha-synuclein misfolds and clumps collectively. These clumps then harm dopamine-producing nerve cells within the mind, which ends up in the standard Parkinson’s signs. Present therapies, primarily drugs that exchange dopamine, typically have unintended effects and lose effectiveness over time.
The protein clumps are believed to be shaped within the intestine wall at a really early stage of the illness, from which they attain the mind cells by way of the vagus nerve, which connects the intestine and the mind.
This course of will be influenced by intestine micro organism. Certainly, rising analysis suggests a shocking hyperlink between PD and the intestine microbiome, the trillions of micro organism residing in our intestines.
Sufferers with Parkinson’s typically have an altered intestine microbiome in comparison with wholesome people and so they typically present extra (intestinal) irritation and a disrupted intestinal barrier.
That’s why the neurology division at College Hospital Ghent (UZ Gent), led by Prof. Patrick Santens, joined forces with Prof. Debby Laukens of Ghent College and the group of Prof. Roosmarijn Vandenbroucke on the VIB-UGent Middle for Irritation Analysis.
The group wished to research whether or not a fecal microbiota transplant (FMT) with wholesome intestine micro organism from a donor might have a big influence on the evolution of Parkinson’s illness signs over one 12 months.
The scientific research confirmed that after 12 months, the actively handled group confirmed considerably extra enchancment in motor signs in comparison with the placebo group.
By way of the nostril into the small gut
The scientific research, named GUT-PARFECT, recruited individuals with early-stage Parkinson’s illness and wholesome donors who donated their stool to the Gentse Stoelgangbank.
All individuals with Parkinson’s illness obtained the stool by means of a tube that was inserted by means of the nostril and superior into the small gut to ship the combination immediately there.
“Our outcomes are actually encouraging!” says Dr. Arnout Bruggeman, researcher at VIB-UGent-UZ Gent and first creator of the research.
“After twelve months, individuals who obtained the wholesome donor stool transplant confirmed a big enchancment of their motor rating, an important measure for Parkinson’s signs.”
The development in motor signs grew to become much more pronounced between the sixth and twelfth month after the transplant, suggesting a possible long-lasting impact.
Moreover, individuals had much less from constipation, a frequent and bothersome symptom for many individuals with Parkinson’s illness. Extra analysis is required to find out whether or not this remedy additionally slows the development of the illness.
Means ahead
This research is a big step ahead within the seek for new remedy choices for Parkinson’s illness.
“As a result of there have been main questions in regards to the feasibility at the beginning of the research, financing this analysis was no simple job,” says Prof. Patrick Santens.
“This analysis was solely potential because of the assist of affected person organizations, donations to the UGent Parkinson Analysis Fund, and the willingness of individuals to bear the relatively invasive procedures.”
“Our research offers promising hints that FMT could be a precious new remedy for Parkinson’s illness,” says Prof. Roosmarijn Vandenbroucke.
“Extra analysis is required, nevertheless it presents a probably protected, efficient, and cost-effective manner to enhance signs and high quality of life for hundreds of thousands of individuals with Parkinson’s illness worldwide.”
“Our subsequent step is to acquire funding to find out which micro organism have a optimistic affect. This might result in the event of a ‘bacterial capsule’ or different focused remedy that might exchange FMT sooner or later,” says Prof. Debby Laukens.
Funding: This research was made potential due to the sufferers and their households who participated within the trial, in addition to the donors from the Gentse StoelgangBank and assist from the Flemish Parkinson’s affected person organizations, VPL and Parkili.
The analysis was funded by the Biocodex Microbiota Basis, the numerous presents to the UGent Parkinson Analysis Fund, and the FWO Program.

“Security and efficacy of faecal microbiota transplantation in sufferers with gentle to reasonable Parkinson’s illness (GUT-PARFECT): a double-blind, placebo-controlled, randomised, section 2 trial” by Roosmarijn Vandenbroucke et al. EClinicalMedicine
Summary
Security and efficacy of faecal microbiota transplantation in sufferers with gentle to reasonable Parkinson’s illness (GUT-PARFECT): a double-blind, placebo-controlled, randomised, section 2 trial
Background
Dysregulation of the intestine microbiome has been implicated in Parkinson’s illness (PD). This research aimed to guage the scientific results and security of a single faecal microbiota transplantation (FMT) in sufferers with early-stage PD.
Strategies
The GUT-PARFECT trial, a single-centre randomised, double-blind, placebo-controlled trial was performed at Ghent College Hospital between December 01, 2020 and December 12, 2022. Individuals (aged 50–65 years, Hoehn and Yahr stage 2) had been randomly assigned to obtain nasojejunal FMT with both wholesome donor stool or their very own stool.
Laptop-generated randomisation was achieved in a 1:1 ratio by means of permutated-block scheduling. Remedy allocation was hid for individuals and investigators.
The first consequence measure at 12 months was the change within the Motion Issues Society-Unified Parkinson’s Illness Score Scale (MDS-UPDRS) motor rating obtained throughout off-medication evaluations. Intention-to-treat evaluation was carried out utilizing a blended mannequin for repeated measures evaluation.
This accomplished trial is registered on ClinicalTrials.gov (NCT03808389).
Findings
Between December 2020 and December 2021, FMT procedures had been performed on 46 sufferers with PD: 22 within the wholesome donor group and 24 within the placebo group. Medical evaluations had been carried out at baseline, 3, 6, and 12 months post-FMT. Full knowledge evaluation was potential for 21 individuals within the wholesome donor group and 22 within the placebo group. After 12 months, the MDS-UPDRS motor rating considerably improved by a imply of 5.8 factors (95% CI −11.4 to −0.2) within the wholesome donor group and by 2.7 factors (−8.3 to 2.9) within the placebo group (p = 0.0235). Antagonistic occasions had been restricted to momentary belly discomfort.
Interpretation
Our findings prompt a single FMT induced gentle, however long-lasting helpful results on motor signs in sufferers with early-stage PD. These findings spotlight the potential of modulating the intestine microbiome as a therapeutic method and warrant an additional exploration of FMT in bigger cohorts of sufferers with PD in numerous illness phases.
