The gut microbiome may trigger RA & predict methotrexate response. ACR Convergence 2025 experts discuss pathogenesis & drug efficacy.
What Can I Eat or Not Eat to Cure My Arthritis?
“What can I eliminate from my diet to cure my arthritis?” is the question every client with arthritis asks me. Numerous case reports document patients who achieved lower markers of inflammation and reduced pain and stiffness associated with the removal of one or two food groups from a diet, but historically, no compelling evidence has…
Gut Instinct: Ankylosing Spondylitis & the Microbiome
CHICAGO—At the 2019 ACR State-of-the-Art Clinical Symposium, an annual gathering featuring talks by key opinion leaders on the most salient topics for practicing rheumatologists and healthcare providers, Jose U. Scher, MD, director of the Microbiome Center for Rheumatology and Autoimmunity at NYU Langone Medical Center, New York City, was the featured speaker. In his remarks,…
Probing the Role of Genes & Microbiome in Ankylosing Spondylitis & RA
Researchers know human leukocyte antigen (HLA) molecules affect susceptibility to disease in general, and immunological disease in particular. In the case of ankylosing spondylitis (AS), the risk is primarily associated with HLA-B27, with smaller effects from other HLA alleles. Current thinking is that AS is caused by the presence of a genetically primed host because…
To Understand Lupus, Study the Gut
Researchers who devote their time to studying lupus are accustomed to considering environmental stimuli such as sunshine and cigarettes. But according to Gregg J. Silverman, MD, a professor in the Department of Medicine and in the Department of Pathology at the New York University (NYU) School of Medicine and co-director of the Musculoskeletal Center of…
Links Between Gut Bacteria and Rheumatoid Arthritis
CHICAGO—At the 2018 ACR/ARHP Annual Meeting, Allen C. Steere, MD, delivered the Rheumatology Research Foundation Memorial Lecture honoring the late Charles M. Plotz, MD: Linking Gut Microbial Immunity with Autoimmunity in Joints in Patients with Rheumatoid Arthritis. Dr. Steere is professor of medicine at Harvard Medical School, Boston, and director of translational research in rheumatology…
Studies Find More Evidence the Microbiome Affects Autoimmune Disease
Evidence is accumulating that the microbiome may be an important part of the pathogenesis of many autoimmune diseases. Two recently published articles report on how translocation of the gut bacterium Enterococcus gallinarum drives autoimmunity in mice and humans, and on the role of other commensal bacteria in triggering immune responses—specifically to the autoantigen Ro60, which…
Looking for Links Between Rheumatoid Arthritis & Gut Bacteria, Mutations
Patients with a specific genetic predisposition for rheumatoid arthritis (RA) may want to take precautions when consuming certain types of meat, dairy and produce grown with cow manure, according to a new study out of the University of Central Florida (UCF) in Orlando. The study, which assessed 100 RA patients, published in the journal Frontiers…
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…
Alterations in the Microbiome Are Associated with Changes in Bone Quality
By treating mice with antibiotics, researchers found that alterations in the gut microbiome impaired the mechanical properties of bone and depleted splenic B and T cell populations. The researchers suspect the decrease in bone strength resulted from the change in the immune system…
