Summary

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint destruction and autoantibody production. Scavenger receptor-A (SR-A), a pattern recognition receptor primarily expressed on myeloid-derived cells, is significantly elevated in the serum of RA patients. Genetic knockout of SR-A completely protects mice from collagen-induced arthritis (CIA). As an SR-A inhibitor, fucoidan markedly suppresses the progression of CIA in mice. Given the potential role of SR-A in RA pathogenesis, the investigators hypothesize that fucoidan may exert therapeutic effects in RA by specifically targeting human SR-A.

This study aims to investigate the efficacy of fucoidan in RA treatment through a multicenter, single-arm, open-label trial, providing original insights into its clinical application. The investigators plan to enroll 40 patients with a 12-week follow-up period. Clinical manifestations, laboratory parameters, and disease activity will be systematically evaluated to assess therapeutic outcomes. The findings will provide evidence-based medical data for RA treatment strategies.
