Gut Microbial Variations Associated With Proton Pump Inhibitor Use in the Boston Puerto Rican Health Study.

ABSTRACT: Proton pump inhibitors (PPI), used to treat gastrointestinal disorders, are associated with alterations in the gut microbiome. However, this is understudied in Puerto Ricans who have unique lifestyle characteristics. Puerto Ricans, including participants of the Boston-Puerto Rican Health Study (BPRHS), report high PPI use. Therefore, we examined gut microbial variations associated with PPI use in the BPRHS. BPRHS is a prospective cohort. 309 BPRHS participants self-reported PPI use and self-collected, metagenomically profiled, stool samples. PPI use was classified as any use in the past 30 days. Cross-sectional associations between gut microbial taxa, functional pathways, and PPI use were examined using omnibus analyses, multivariate linear modeling in MaAsLin2, and random forest classifie
