Pearls of Wisdom from an Expert: Challenging ILD Cases with a Pulmonologist-Rheumatologist
Erin Wilfong, MD, PhD, shared her niche expertise in connective tissue disease ILD (CTD-ILD) via case-based learning during a session of the 2022 ACR Education Exchange.
A Closer Look at Antibodies in RA: How Anti-Citrullinated Protein Antibodies, Anti-Modified Protein Autoantibodies & Rheumatoid Factor Activity Overlap
Recent evidence on how anti-citrullinated protein antibodies, anti-modified protein autoantibodies and rheumatoid factor activity overlap in RA demonstrate new ideas for diagnostics and pathophysiology.
A Close Look at Antibodies in RA
ACR CONVERGENCE 2020—Recent research findings suggest rheumatologists need to take a closer look at two gold standard autoantibodies used to diagnose seropositive rheumatoid arthritis (RA)—rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP), according to Caroline Grönwall, PhD, and Miriam Shelef, MD, PhD, who discussed Antibodies in RA: Beyond Citrullination & Back to Rheumatoid Factor at…
9/11 Survivors at Increased Risk for Autoimmune Disease
Miller-Archie et al. set out to determine whether dust exposure and PTSD are associated with an increased risk of systemic autoimmune disease in a 9/11-exposed cohort not included in previous studies of members of the Fire Department of New York and whether this association differs between 9/11 responders and community members.
PAD4 Antibodies May Help Predict Treatment Response in Rheumatoid Arthritis
A study published in Arthritis & Rheumatology highlights how the presence of autoantibodies to peptidylarginine deiminase (PAD) may eventually be used to influence treatment decisions in the management of rheumatoid arthritis (RA), sharpening our understanding of disease subtypes.1 Although follow-up prospective studies are needed, these findings underline some intriguing areas for future investigations in immunobiology….
The Role of Autoreactive B Cells in Rheumatoid Arthritis
The body uses B cells to produce antibodies that can fight off infection by invading antigens and bacteria. But in rheumatoid arthritis (RA), the immune system produces autoantibodies that work against the body’s proteins to attack joint tissues. Researchers believe this process is helped along by autoreactive B cells that live in bone matter and…
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…
The History & Future of Anti-Citrullinated Protein Antibodies (ACPAs)
Anti-citrullinated protein antibodies (ACPAs) are now viewed as critical diagnostic and prognostic markers for rheumatoid arthritis (RA). Research into the pathophysiology of these autoantibodies has proven to be a ripe area of investigation, opening up many promising avenues for better understanding the etiology and pathogenesis of RA. Ultimately, work utilizing these autoantibodies may also allow…
One Step Closer to Personalized Medicine for RA Patients
New research is translating the molecular signals in RA patients to better understand the earliest signs of disease. The work on using these signs to test the effects of RA treatment may help rheumatologists determine the most effective treatment for individuals…
