ABSTRACT
Recent studies point to intestinal permeability as an important factor in the establishment and development of rheumatoid arthritis (RA). Tight junctions (TJs) play a major role in intestinal homeostasis. The alteration of this homeostasis is related to RA. Furthermore, RA patients present dysbiosis and a lower microbiota diversity compared to healthy individuals. A cross-sectional study including RA patients and sex- and age-matched healthy controls was performed. The quantification of TJ proteins was carried out by ELISA. Gut microbiota was evaluated by NGS platform Ion Torrent S. The inflammatory variables included were DAS28, CRP, inflammatory cytokines (IL-6, IL-1, TNF-α) and oxidised LDL. Claudin-1 levels showed significant differences between groups. Results evidenced a correlation between claudin-1 values and age (r -0.293; p < 0.05), IL6 (r -0.290; p < 0.05) and CRP (r -0.327; p < 0.05), and between zonulin values and both age (r 0.267; p < 0.05) and TNFα (r 0.266; p < 0.05). Moreover, claudin-1 and CRP levels are related in RA patients (ß -0.619; p 0.045), and in patients with high inflammatory activity, the abundance of the genus Veillonella is positively associated with claudin-1 levels (ß 39.000; p 0.004).
