    Induction of antibodies against biologics

    The development of antinuclear antibodies and autoimmune disorders has been observed after treatment with TNF- inhibitors (box 3, table 2).12 15 To our knowledge, no autoimmunity related phenomena after treatment with alefacept or efalizumab have been reported. Besides its important role as a proinflammatory cytokine, TNF- also causes serious immunosuppressive effects by regulating antigen-presenting cell functions and apoptosis of potentially autoreactive T cells.w27 Therefore, antagonising TNF- and its suppressive effects may lead to the development or unmasking of autoimmune diseases.21 22 It remains unclear whether the detection of anti-doublestranded DNA antibodies is predictive of an increased risk of developing lupus-like syndrome or systemic lupus erythematosus. Box 4 gives details of trials of autoimmunity during treatment with TNF- inhibitors.

    Lupus-like syndrome

    Leukocytoclastic vasculitis

    Systemic lupus erythematosus

    Antinuclear antibodies

    Anti-doublestranded DNA

    Case reports of drug induced lupus after treatment with infliximab and etanercept have been published22 w28-w31 and a French national survey found 12 cases of systemic lupus erythematosus after anti-TNF- therapy (in about 7000 patients treated) for inflammatory arthritis.23 Despite the relatively high incidence of anti-doublestranded DNA antibodies, the frequency of clinical lupus related to anti-TNF- treatment is very low. No evidence exists that patients who develop new autoantibodies are at significantly increased risk of developing drug induced lupus, but the long term impact remains unclear.21 24 The risk of developing self limiting autoimmune syndromes seems in most cases to be small compared with the impressive clinical benefit the patients experience with these drugs. Nevertheless these findings underline the need for further monitoring of autoantibody production in patients treated with TNF- antagonists over longer periods. Physicians therefore need to look for signs and symptoms of autoimmune disorders when using TNF- antagonists.
