Role of Gut Microbiota and Metabolite Remodeling on the Development and Management of Rheumatoid Arthritis: A Narrative Review

Abstract

Rheumatoid arthritis (RA) is a chronic autoimmune disease that has a serious impact on both human health and animal production. The gut microbiota is a large and complex symbiotic ecosystem in animals, and the imbalance of gut microbiota is closely related to the pathogenesis of numerous diseases, including RA. The interactions among the gut microbiota, intestinal barrier, and immune system play key roles in maintaining intestinal homeostasis and affecting the development of RA. Regulating intestinal flora and metabolites provides new ideas for the prevention and treatment of RA. Probiotics can regulate the balance of intestinal flora and metabolites, improve the immune environment, and provide novel therapeutic strategies against RA. In order to summarize the role of gut microbiota and metabolite remodeling in the development and management of RA, this review will elaborate on the role of intestinal flora imbalance in the pathogenesis of RA and assess prospective therapeutic approaches that target the gut flora. Understanding the interaction among intestinal flora, metabolites, and RA will help to clarify the pathogenesis of RA and develop innovative and personalized therapeutic interventions against chronic autoimmune diseases.
