SAN DIEGO—The understanding of the microenvironment in which immune cells interact with stromal cells in the synovium of psoriatic arthritis (PsA) and rheumatoid arthritis (RA) is deepening, potentially giving clues for treatments. As this understanding improves, so does the appreciation for its astounding complexity, an expert said here in a session at ACR Convergence, which…

Top Research in Axial Spondyloarthritis Presented at ACR Convergence 2022
PHILADELPHIA—Approximately 100 research abstracts on axial spondyloarthritis (axSpA) were accepted for presentation at ACR Convergence 2022. It is exciting to see a wealth of research on axSpA being undertaken worldwide. Here, we highlight important points from 10 of these studies. 1. Abstract 0378: Prevalence of Axial Spondyloarthritis (axSpA) in Patients Treated for Chronic Back Pain…
Scleroderma & the Gut: New Frontiers in Diagnosis & Tips on Management
McMahan et al. examined how abnormal gastrointestinal (GI) transit may contribute to GI severity and symptoms in patients with systemic sclerosis (SSc). About 90% of people with SSc have GI tract involvement, and understanding the connection between GI symptoms, their severity and abnormal GI transit may permit targeted therapeutic approaches for these patients.
Gut Feeling: A Comprehensive Look at the Pathogenesis, Management & Treatment of Inflammatory Bowel Disease
Patients with autoimmune diseases, such as spondyloarthritis, are at risk of developing inflammatory bowel disease. Here are considerations for its management and treatment.
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…
Gut Microbe, Prevotella copri, Implicated in RA Pathogenesis
New research reinforces the hypothesis that the gut microbiome triggers mucosal and systemic immune responses in patients with rheumatoid arthritis. The research, published in Arthritis & Rheumatology May 2017, found that subgroups of patients with RA have differential immunoglobulin G (IgG) or IgA immune reactivity with Prevotella copri, an intestinal microbe that appears to be…
Volatility of the Gut Microbiome Tied to IBD
NEW YORK (Reuters Health)—Fluctuations in the gut microbiome over time could underlie inflammatory bowel disease (IBD), including Crohn’s and ulcerative colitis, researchers suggest. “Both the state and the dynamics of the human gut microbiome in healthy individuals are highly personalized. Although cross-sectional studies have revealed dysbiosis of the gut microbiome in IBD, little is known…
Rheumatoid Arthritis Research Provides New Insights on Risk Factors, Identification Tools, Intervention
Established wisdom holds that patients with rheumatoid arthritis (RA) will fare better if their disease is diagnosed as early as possible, and treatments with disease-modifying drugs are started before inflammation can do more damage to joints and tissue. Usually, early diagnosis means spotting the clinical signs of disease, but new research tells us more about…
Insight into Infectious Diseases Could Lead to Preventive Vaccines for Some Rheumatic Illnesses
CHICAGO—Medicine is in the middle of an infectious-disease “revolution” that seems almost destined to lead to prevention through immunization of many diseases, including rheumatic illnesses, that never were previously thought to involve transmissible agents, an infectious disease specialist said in a session at the ACR’s 2016 State-of-the-Art Clinical Symposium. An array of unlikely and fascinating…
The Gut Microbiome Influences Postmenopausal Bone Loss
Bone health has been successfully improved by using probiotics to influence the gut microbiome in postmenopausal women with osteoporosis. New research has gained insight into this process, uncovering that sex steroid depletion increases gut permeability resulting in inflammation and pathology in mice. Treatment with probiotics also prevents this increase in gut permeability and bone loss associated with sex steroid depletion…
