Novel Markers for Rheumatoid Arthritis, Anti-CarP, Anti-Sa, and Anti-CEP1, Are More Frequently Positive and Higher in Titer in RA Patients with Higher Vectra® Disease Activity Scores

Autoantibodies against citrullinated and carbamylated proteins in RA patients may be associated with more active disease and higher risk of developing joint erosions, and Vectra® is a blood test that yields a RA disease activity (DA) score from 1 to 100 that is low, moderate or high. In this abstract, 120 patient samples were analyzed to assess the relationship of DA as measured by Vectra® Score and the presence of novel autoantibody markers with potential prognostic value.
