    RA-ILD patients exhibit specific gut microbial alterations, including enrichment of Escherichia/Shigella and depletion of Roseburia and Ruminococcus.

  • 2

    Alpha and beta diversity of gut microbiota did not significantly differ among RA-ILD patients, RA-non-ILD patients, and healthy controls.

  • 3

    Pro-inflammatory genera positively correlated with disease activity, while butyrate-producing genera showed a negative correlation.

  • 4

    Co-occurrence network analysis indicated that RA patients have a more complex microbial network compared to healthy controls and RA-ILD patients.

  • 5

    The study suggests that gut microbiota changes may play a role in RA-ILD pathogenesis through the gut-lung axis, warranting further investigation.
