Darmmikrobiota und rheumatoide Arthritis: von der Pathogenese zu neuen therapeutischen Strategien

Abstract

Rheumatoid arthritis (RA) is an autoimmune disease with progressive joint disorder. The complex interplay of genetic and environmental influences is important for the development of the disease. A growing body of evidence has shed light on the association of dysbiosis of gut microbiota with RA. Certain gut microbial strains have been shown to inhibit or attenuate immune responses in RA experimental models, suggesting that specific species among intestinal commensal bacteria may play either a pathogenic or a protective role in the development of RA. Oral intake of probiotics/prebiotics can therefore represent a therapeutic approach for RA treatment. However, the relevant scientific work has only just begun, and the available data in this field remain limited. Fortunately, utilization of new sequencing technologies allows expanded research on the association of intestinal bacterial flora and human diseases to be attempted. In this review, we summarize the role of gut microbiota in RA progression and address how specific bacterial strains regulate the immune response in disease process. Probiotics/prebiotics in the treatment of RA is also discussed.
