  1. Patient had persistent specific IgM antibodies and erosive arthritis for two years before treatment.
  2. † gene expression in patient peripheral blood mononuclear cells compared to those observed in cells from three healthy controls using real-time RT-PCR. Results shown as fold expression compared to control values. Inflammatory arrays were performed using RT2 Profiler PCR Array System (Ref: APHS-011B, SuperArray, Frederick, USA, http://www.superarray.com
  3. †† Comparison of gene expression before MTX treatment and following 4 months therapy
