Key clinical point: Presence of autoantibodies for cyclic citrullinated peptide (anti-CCP2), load of anticitrullinated protein antibody (ACPA) fine-specificities, and immunoglobulin M (IgM) rheumatoid factor (RF) at diagnosis of rheumatoid arthritis (RA) increased the risk for incident venous thromboembolic events (VTE) in patients with RA.
Major finding: Positivity for IgG anti-CCP2 (hazard ratio [HR] 1.33; 95% CI 1.00-1.78) and IgM RF (HR 1.38; 95% CI 1.04-1.83) increased the risk for incident VTE. Additionally, the risk increased with the number of ACPA fine-specificities expressed (Ptrend = .033).
Study details: This prospective cohort study analyzed 2782 patients with newly diagnosed RA who reported 213 first-ever VTE.
Disclosures: This study was supported by the Swedish Research Council, NordForsk, and others. Four authors declared being employees or part-time employees, paid advisors, or founders of different companies. Two authors reported owning patents for peptides and their use for diagnostic purpose.
