Antibodies overlap in palindromic rheumatism (PR) and rheumatoid arthritis (RA). (a) PR patients, overlap between Anti-FCS, Anti-CFFHP and ACPA; (b) RA patients, overlap between Anti-FCS, Anti-CFFHP and ACPA; (c) PR patients, Anti-CarP (Anti-FCS and Anti-CFFHP) isotypes overlap; and (d) RA patients, Anti-CarP (Anti-FCS and Anti-CFFHP) isotypes overlap.

ACPA, anti-citrullinated protein/peptide autoantibodies; Anti-CFFHP, anti-chimeric fibrin/filaggrin homocitrullinated peptide antibodies; Anti-FCS, anti-carbamylated fetal calf serum antibodies; Ig, immunoglobulin.
