Background/Purpose: Pathogen-associated transient antiphospholipid antibodies suggest a microbial trigger for antiphospholipid syndrome (APS). We hypothesized that the gut microbiota could represent a chronic stimulus in APS patients and defined the fecal microbiome and IgA-coated microbiota in APS patients over time and correlated them with autoantigen-related responses.
Conclusion: High-throughput sequencing of APS gut microbiomes revealed a persistent enrichment of the genus Slackia over time, particularly among the anti-DI IgG+ APS patients. Slackia is capable of producing phospholipids including cardiolipin. We speculate that gut commensal-derived cardiolipin contributes to a conformational change of
