POTS patients exhibit increased circulating norepinephrine levels with exaggerated sympathetic nervous system response upon standing. Emerging evidence suggests a role for the gut microbiome in cardiovascular disorders. However, the etiology of POTS and whether the gut microbiome plays a role are not fully elucidated. We assessed whether the gut microbiome and fecal short-chain fatty acids were different in POTS patients (N=25) compared to healthy control (N=23) women. Fecal samples were collected and analyzed using shotgun sequencing. Alpha and beta diversity were similar between groups. We observed no differences in bacteria at the phylum levels or Firmicutes to Bacteroidetes ratio. We found no significant differences at the genus level, but observed trends in certain bacteria. Further studies are needed to assess the role of the alterations observed at the genus level."],"repository":["ENA"],"description_synonyms":["digestive canal, Microbial Community Composition, AI747421, Community Composition, orthostatic intolerance., Bowel, gut, Microbiomes, Microbial Community Compositions, Microbial Community, Microbial Community Structure, Gus-u, alimentary tract, Community Structure, Gus-t, Gus-s, Gus-r, Microbial, Concept, Human, Composition, Soldiers heart, gut tube, Gus, Gur, neurocirculatory asthenia, Role Concept, Gut, g, Roles, gastrointestinal system, Role Concepts, Role, Microbial Community Structures, Concepts, Microbiotas, asd, adult alimentary canal, alimentary system, intestines, Human Microbiomes, Microbial Communities, Community, Human Microbiome, Microbiome"],"name_synonyms":["digestive canal, Microbial Community Composition, AI747421, Community Composition, orthostatic intolerance., Bowel, gut, Microbiomes, Microbial Community Compositions, Microbial Community, Microbial Community Structure, Gus-u, alimentary tract, Community Structure, Gus-t, Gus-s, Gus-r, Microbial, Human, Composition, Soldiers heart, gut tube, Gus, Gur, neurocirculatory asthenia, Gut, g, gastrointestinal system, Microbial Community Structures, Microbiotas, asd, adult alimentary canal, alimentary system, intestines, Human Microbiomes, Microbial Communities, Community, Human Microbiome, Microbiome"],"additional_accession":[]},"is_claimable":false,"name":"Gut Microbiota in POTS","description":"Characterizing the Role of the Gut Microbiota in POTS","dates":{"last_updated":"2022-04-28","first_public":"2022-04-28"},"accession":"PRJEB52272","cross_references":{}}
