| 1 | Effects of Resistant Starch on Symptoms,Fecal Markers,and Gut Microbiota in Parkinson’s Disease—The RESISTA-PD Trial显示文摘The composition of the gut microbiota is linked to multiple diseases,including Parkinson’s disease(PD).Abundance of bacteria producing short-chain fatty acids(SCFAs)and fecal SCFA concentrations are reduced in PD.SCFAs exert various beneficial functions in humans.In the interventional,monocentric,open-label clinical trial “Effects of Resistant Starch on Bowel Habits,Short Chain Fatty Acids and Gut Microbiota in Parkinson’s Disease”(RESISTA-PD;ID:NCT02784145),we aimed at altering fecal SCFAs by an 8-week prebiotic intervention with resistant starch(RS).We enrolled 87 subjects in three study-arms:32 PD patients received RS(PD+RS),30 control subjects received RS,and 25 PD patients received solely dietary instructions.We performed paired-end 100 bp length metagenomic sequencing of fecal samples using the BGISEQ platform at an average of 9.9 GB.RS was well-tolerated.In the PD+RS group,fecal butyrate concentrations increased significantly,and fecal calprotectin concentrations dropped significantly after 8 weeks of RS intervention.Clinically,we observed a reduction in non-motor symptom load in the PD+RS group.The reference-based analysis of metagenomes highlighted stable alpha-diversity and beta-diversity across the three groups,including bacteria producing SCFAs.Reference-free analysis suggested punctual,yet pronounced differences in the metagenomic signature in the PD+RS group.RESISTA-PD highlights that a prebiotic treatment with RS is safe and well-tolerated in PD.The stable alpha-diversity and beta-diversity alongside altered fecal butyrate and calprotectin concentrations call for long-term studies,also investigating whether RS is able to modify the clinical course of PD. | Anouck Becker Georges Pierre Schmartz Laura Groger Nadja Grammes Valentina Galata Hannah Philippeit Jacqueline Weiland Nicole Ludwig Eckart Meese Sascha Tierling Jorn Walter Andreas Schwiertz Jorg Spiegel Gudrun Wagenpfeil Klaus Faßbender Andreas Keller Marcus M.Unger | 2022 | Genomics, Proteomics & Bioinformatics2022，20，2： | 0 |
