TNF-inhibitor induced lupus in a patient treated with adalimumab for rheumatoid arthritis.

Anti-tumor necrosis factor induced lupus (ATIL) is a rare side effect reported in patients treated with anti-tumor necrosis factor medications such as infliximab, etanercept and adalimumab. Of the three, this condition has been least commonly reported secondary to adalimumab. In this report, we present a case of ATIL in a patient treated for rheumatoid arthritis (RA) with adalimumab. This report will increase physician awareness of the warning signs, diagnostic options and potential complications of ATIL. In this patient, adalimumab was discontinued and treatment was started, leading to improvement in the patient's status.
