Anti-CarP antibodies may be positive in about 10% of early RA patients who are RF-negative and anti-CCP-negative and may be present years before the onset of RA symptoms.1,2 Anti-CarP is associated with more active disease and higher risk of developing joint erosions.1 Anti-CarP levels especially in combination with RF- and Anti-CCP-positivity may predict joint erosion and radiographic progression.1
