SAN FRANCISCO—The organisms in the gut are remarkably malleable with diet, dangling the possibility that diseases could potentially be affected by the food that people eat, according to an expert here at the 2015 ACR/ARHP Annual Meeting. Diet Starting with studies of animal feces from zoos and from the wild, in which researchers found that…
NEW YORK (Reuters Health)—The route of iron replacement therapy alters the gut microbiome and metabolomics in patients with inflammatory bowel disease (IBD), but the route is unrelated to disease activity and quality of life, according to a new study. “Crohn’s disease patients are extremely fragile to disturbances and one might speculate about consequences in long-term…
Despite the relative novelty of the human microbiome as an area of study, a substantial body of evidence has accumulated addressing its potential involvement in the pathogenesis of rheumatic disease. This review article explores the available data in animal and human studies, focusing on the role of the intestinal microbiome in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and the spondyloarthritidies (SpA)…
Interactions between an individual’s genetic background and their exposure to environmental factors are thought to result in a cascade of immune reactions, ultimately leading to the development of autoimmune diseases such as rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), systemic lupus erythematosus (SLE) and juvenile dermatomyositis.1,2 For example, an environmental factor that conclusively affects susceptibility…
NEW YORK (Reuters Health)—Exposure to probiotics in the first few weeks of life is associated with a reduced risk of islet autoimmunity, according to results from the TEDDY study. “Early supplementation of probiotics may be important but we need more research on this,” Dr. Ulla Uusitalo from University of South Florida in Tampa told Reuters…
Researchers determined IL-26 serves as a potent antimicrobial that promotes the immune sensing of both bacterial and host cell death…
NEW YORK (Reuters Health)—Commensal microbes in the gut can activate retina-specific T cells that go on to cause autoimmune uveitis in a mouse model, researchers report. “These findings allow us to understand the biological basis for the disease,” lead author of the study, Dr. Rachel Caspi from National Eye Institute at the NIH in Bethesda,…
NEW YORK (Reuters Health)—Patients with rheumatoid arthritis (RA) have alterations in their oral and gut microbiomes that partially normalize with treatment, according to results from a metagenome-wide association study. The microbiota influence metabolic and immune homeostasis, and microbial triggers have been postulated in RA, but little is known about the oral and gut microbiomes of…
The Friday night press release: When a politician or any public figure needs to disclose unfavorable news, chances are they will release it sometime on a late Friday afternoon or evening, hoping that nobody is paying attention. In fact, this behavior was coined “the take out the trash day” on the television political drama, The…
Although compelling data exist to support a link between periodontal disease (PD) and the development of rheumatoid arthritis (RA), cementing the association will require extensive investigative work.1 However, in reviewing the literature of the past 10 years, Elliot D. Rosenstein, MD, director, Institute for Rheumatic and Autoimmune Diseases at Overlook Medical Center, Summit, N.J., and…
