Besides anti-drug antibodies, anti-nuclear antibodies and anti-DNA antibodies are
often induced in patients with rheumatoid arthritis treated with tumor necrosis
factor inhibitors. We examined the association between immunogenicity,
autoantibody production, and serum cytokine profiles in patients with rheumatoid
arthritis treated with infliximab. Japanese patients with rheumatoid arthritis (n
= 57) were retrospectively examined. Serum trough levels of infliximab, anti-drug
antibody, anti-nuclear antibody, and anti-DNA (Farr), anti-single-stranded DNA
and anti-double-stranded DNA antibodies were measured. Interleukin-6,
interferon-?, interferon-?, and B-cell activating factor levels were also
measured in the same sera. Then, we validated the association between anti-drug
antibody and these serum markers along with clinical response to infliximab.
Anti-drug antibodies developed in twenty-one patients (36.8%), whose serum trough
levels of infliximab were significantly lower than those in anti-drug
antibody-negative patients (0.09 ± 0.03 vs. 2.48 ± 0.326 ?g/mL, p < 0.0001).
There were no significant differences in clinical backgrounds between the two
groups. The anti-drug antibody-positive patients were more likely to develop
anti-nuclear antibody titers of ? ×160 compared to the negative patients (14 to
57% vs. 17 to 33%). In addition, anti-DNA antibodies (Farr) (from 1.5 ± 0.4 to 35
± 17 IU/mL, p = 0.0001), especially IgM-anti-double stranded DNA antibody (from
5.1 ± 0.7 to 41 ± 8.9 IU/mL, p < 0.0001), and IgG-anti-single stranded DNA
antibody (from 13 ± 1.1 to 35 ± 13, p = 0.0145) were significantly increased in
anti-drug antibody-positive but not in negative patients. Moreover, the anti-drug
antibody-positive, but not the negative patients, showed significant increased
levels of interferon-? (from 248.7 ± 102.3 to 466.8 ± 135.1 pg/mL, p = 0.0353)
and B-cell activating factor (from 1073 ± 75.1 to 1387 ± 136.5 pg/mL, p = 0.0208)
following infliximab treatment. The development of anti-drug antibody against
infliximab and lupus-like autoantibody production in patients with rheumatoid
arthritis treated with infliximab can be linked each other along with increased
lupus-associated cytokine levels including type I interferons.
