Key clinical point: The risk of progression to rheumatoid arthritis (RA) increased with rises in cyclic citrullinated peptide (CCP) antibody levels in CCP-positive adult patients.
Major finding: Over 1,047 person-years of follow-up, 73 patients (22%) developed rheumatoid arthritis, and 46% of patients with high levels of CCP antibodies developed rheumatoid arthritis within 5 years of entering the study.
Study details: The data come from a retrospective cohort study of 340 adults who were cyclic citrullinated peptide (CCP) antibody positive but without RA at baseline.
Disclosures: The researchers had no financial conflicts to disclose.
