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…
Although systemic lupus erythematosus still does not have a definite cause or cure, rheumatologists and researchers over the past 50 years have witnessed and contributed to a great deal of progress that helps patients, says Peter H. Schur, MD, director emeritus of the Lupus Center, Brigham and Women’s Hospital, and professor, Harvard Medical School, Boston. Dr. Schur’s…
WASHINGTON, D.C.—Researchers at the 2016 ACR/ARHP Annual Meeting discussed how they are exploring the immune system in search of groundwork for new rheumatoid arthritis (RA) treatments. The new avenues, supported by the Rheumatology Research Foundation, involve T cell adhesion, new understanding of the role of macrophages and insights into the way IgG glycans function. T…
Erdheim-Chester disease (ECD) is a rare, non-Langerhan’s cell histiocytosis characterized by tissue infiltration of CD68-positive and CD1a-negative foamy histiocytes.1 ECD was discovered as a lipid granulomatosis in 1930 by Jakob Erdheim and his pupil, William Chester, and approximately 500 cases have been described to date.1 ECD has a heterogeneous course and prognosis ranging from an…
WASHINGTON, D.C.—Rheumatology researchers look for next-generation treatments, healthy interventions, and genetic and microbial clues to disease pathogenesis and therapy response, according to new studies presented at a Nov. 15, 2016, press conference at the 2016 ACR/ARHP Annual Meeting. OA & Physical Function How do you know when a patient with knee osteoarthritis (OA) has the…
Two previously unidentified cellular players in the pathogenesis of primary Sjogren’s syndrome (pSS) have been discovered: a regulatory T cell (Prdm1+eTreg) and a helper T cell (Il21+Th1). In the study, researchers also identified the transcriptional signatures of these cells and their differential dependency on the lymphotoxin/LIGHT signaling axis, which may guide future therapeutic interventions…
Obesity has an established systemic inflammatory component. Could that be a trigger for the inflammation seen in rheumatoid arthritis (RA) and other rheumatic diseases? Although there is no direct scientific evidence, both mechanistic and epidemiologic clues do give some intriguing suggestions of a possible link. “At first, we thought that fat was involved only in…
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…
LONDON—Research continues to advance in understanding the causes, prediction and management of the stages of early arthritis before full-blown clinical disease, and an expert highlighted some of the latest of these encouraging findings at the Annual Congress of the European League Against Rheumatism (EULAR) 2016. Many of the genetic and environmental risk factors are known,…
LONDON—New research shows that the synovial compartment appears to have a special role in the chronic nature of rheumatoid arthritis (RA), providing refuge for plasma cells and giving them an ideal environment in which to produce antibodies against citrullinated protein antigens (ACPA). The findings were presented at the Annual Congress of the European League Against…
