Multiplex Analyses of Antibodies Against Citrullinated Peptides in Individuals Prior to Development of Rheumatoid Arthritis
Abstract Objective The presence of antibodies against cyclic citrullinated peptides has been demonstrated to precede the onset of symptoms of rheumatoid arthritis (RA) by several years. The aim of this study was to analyze antibodies against 10 citrullinated autoantigen‐derived peptides for reactivi...

The study was performed in 409 individuals, 386 of whom donated 717 blood samples before the onset of symptoms of RA (pre‐patients). The median period of time predating the onset of RA was 7.4 years.

Results The fluorescence intensity of antibodies against Fibβ36–52, Fibβ74, CEP‐1, citC1 III , and filaggrin was significantly increased in pre‐patients compared with controls ( P < 0.001). The levels of the earliest‐detectable antibodies (Fibα591 and Vim60–75) fluctuated over time, with only a slight increase after the onset of disease.
