    OBJECTIVE: Autoimmune responses in rheumatoid arthritis (RA) are marked by the presence of anti-citrullinated protein antibodies (ACPA.


    The autoimmune response in rheumatoid arthritis (RA) is marked by the presence of anti-citrullinated protein antibodies (ACPA.


    Methods: We analyzed IgG ACPA VDG profiles from seven different cohorts from Japan, Canada, the Netherlands, and Sweden using liquid chromatograph.


    The researchers analyzed IgG ACPA VDG profiles from seven different cohorts from Japan, Canada, the Netherlands, and Sweden using liquid chromatograph.


    IgG ACPA VDG was significantly increased at disease onset ( P < 0001 ) and was associated with pre-diagnostic ACPA levels and epitope sprea.


    The abundance of IgG ACPA VDG increases with RA onset and correlates with the maturity of the ACPA respons.
