NOVEL ANTIBODY BIOMARKERS THAT PREDICT FAILURE TO ACHIEVE EARLY AND SUSTAINED DISEASE REMISSION OR LOW DISEASE ACTIVITY AFTER INTENSIVE FIRST-LINE THERAPY IN RHEUMATOID ARTHRITIS

Abstract

Scientific Abstracts 299 ANOSIM). Detailly, at the genera level, IIM patients had a higher abundance of Ente-rococcus, Veillonella, Streptococcus, et al. and a lower abundance of Roseburia, Lachnospira, Klebsiella, et al(Figure 1D, p < 0.05). In IIM patients, Fusobacteriota correlated positively with the ratio of Th1 cells (Figure 1E, p < 0.01), and there was a significant positive correlation between Synergistota and B lymphocyte (Figure 1E, p < 0.01). Besides, Euryarchaeota and Cyanobacteria were both positively and significantly related to IL-6, IFN-γ and C-reactive protein (CRP) (Figure 1E, p < 0.001). Conclusion: Richness and diversity of intestinal flora in IIM patients were impaired, which might participate in the pathogenesis of IIM by disturbing lym-phocyte subpopulations and cytokines. Regulating intestinal flora and restoring homeostasis might become a critical therapeutic methods of IIM. REFERENCES: [1] Xu Y, Sun J, Wan K, et al.
