Background & Objectives Rheumatoid arthritis (RA) is a chronic autoimmune disease associated with immune responses to the patient’s own antigens and characterized by inflammation and substantial joint destruction. Prevotella copri, a gut commensal bacterium, has been reported to be an immune-relevant organism in individuals with RA. This study sought to evaluate antibody responses to anti-P….
Diet, Microbes & Inflammation: Unique Microbial Genetic Strains in Inflammatory Disease, Plus a Possible Arthritis Diet
Experts at ACR Convergence 2020 addressed how diet & the body’s microbiome affect chronic diseases.
The Effects of IL-17A Inhibitors on the Microbiota
The use of an interleukin (IL) 17A inhibitor resulted in gut microbial dysbiosis and features of subclinical intestinal inflammation in a subgroup of psoriatic arthritis (PsA) and spondyloarthritis (SpA) patients, according to a multidisciplinary, collaborative study across several institutions published in Arthritis & Rheumatology.1 Understanding the downstream effects of these perturbations is an important step…
Study Assesses the Role of Genetics & the Gut in Reactive Arthritis
Genes may predispose people to have certain microbial signatures in their gut that, in turn, make them susceptible to developing reactive arthritis. This is the main finding of a recent study in which researchers investigated whether perturbations in the intestinal microbiome play a role in susceptibility to reactive arthritis in the face of triggers, such…
Gut Microbiota Directly Affects Inflammatory Arthritis
Gut microbiota may provide insight into important environmental triggers for autoimmune diseases. New research in mice indicates that intestinal dysbiosis triggers a mucosal immune response that stimulates T and B cells, which are critical to the development of inflammatory arthritis…
