ATLANTA—A key goal for rheumatology researchers and clinicians is to predict through specific biomarkers if someone will, at some point in their future, develop rheumatoid arthritis (RA). If so, the disease could be prevented or stopped before the inflammation and ravaging begins, explained researchers during a Basic Science lecture at the 2019 ACR/ARP Annual Meeting…
Antibodies Can Spot RA in the General Population
NEW YORK (Reuters Health)—Anti-citrullinated protein antibodies (ACPA), particularly high anti-CCP2 titers, can diagnose rheumatoid arthritis (RA) in the general population with a high degree of accuracy, a Swedish study suggests. ACPA are highly specific for RA, but until now the diagnostic accuracy of ACPA in the general population has not been “thoroughly assessed,” note Dr….
ACPA-Positive & ACPA-Negative Patients with RA: The Difference Begins in the Lungs
A new study from Stockholm, Sweden, strengthens the link between the lungs and anti-citrullinated protein antibody (ACPA)–positive RA. After analyzing the bronchial tissue of untreated patients with early RA, researchers found the patients’ lungs had signs of immune cell accumulation and activation…
More Evidence Biomarkers Predict RA Relapse with DMARD Taper
NEW YORK (Reuters Health)—For rheumatoid arthritis (RA) patients in stable remission, a panel of inflammatory markers in blood can help predict the odds of relapse when disease-modifying anti-rheumatic drug (DMARD) therapy is tapered, say researchers from Germany. The multibiomarker disease activity (MBDA) score, when combined with anticitrullinated protein antibody (ACPA) testing, can predict relapse in…
Bronchial Tissue Immune Activation Seen in Early Rheumatoid Arthritis
NEW YORK (Reuters Health)—Patients with untreated early rheumatoid arthritis (RA) show signs of immune activation and local inflammation in their bronchial tissues, researchers from Sweden report. Previous studies have shown that patients with RA have shared citrullinated epitopes in the lungs and joints, as well as anticitrullinated protein antibodies (ACPA) in bronchoalveolar lavage (BAL), suggesting…
EULAR 2015: Role of ACPA Positivity in Osteoarthritis
ROME, Italy—The role of ACPA positivity in osteoarthritis is coming more into focus, with results from recent studies by researchers in Germany showing that ACPA positivity apparently works in concert with rheumatoid factor positivity to enhance bone erosion and that ACPA-positive patients show signs of bone erosion before they have clinical signs of arthritis. The…
ACR/ARHP Annual Meeting 2012: Can Studying Anticitrullinated Protein Antibodies Put Us on Track to Stop RA?
Research is needed before therapies involving them can be used in the clinic and finely tailored for maximum benefit
