Evaluation of the disease-modifying effects of Aureobasidium pullulans AFO-202 strain produced Beta-Glucan in Parkinson’s disease – Results of a pilot clinical study
Bibliographic record
Abstract
Abstract The aetiology of Parkinson’s disease (PD) has been linked to the aggregation and spread of misfolded alpha-synuclein via the gut-brain axis. We previously reported the effects of a biological response modifier, beta-glucan, produced by the AFO-202 strain of Aureobasidium Pullulans , which improves clinical symptoms and controls gut Enterobacteriaceae associated with curli and amyloid-alpha-synuclein production. In this study, we report the effects of beta-glucan on PD. Eight patients with PD were recruited, five of whom completed the study. Each participant was administered 3 g of AFO-202 B-glucan orally daily for 90 days in addition to their regular prescription drugs. Pre- and post-study comparison revealed that the mean UPDRS decreased from 43.25 ± 13.75 at baseline to 40 ± 13.65 post intervention. Improvements in cognition, walking and balance, postural stability, and constipation scales were observed. The mean constipation severity score decreased from 3 ± 1.73 to 1.75 ± 0.43 post intervention. The serum creatinine kinase levels decreased and the blood glucose and lipid levels normalised. The MRI Parkinson’s index (MRPI) improved in one patient. This safe AFO-202 B-glucan produced beneficial disease-modifying improvements in the UPDRS and MRI that were clinically significant in the short timeframe of 90 days. Further validation in larger, longer-term clinical trials will help confirm the use of beta-glucan as a potential adjuvant treatment for PD which may pave way for future evaluations of these beta-glucans in other synculeinopathies as well Lewy-body related pathogenesis.

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.
