Adalimumab-induced lupus erythematosus.

Adalimumab, an anti-tumour necrosis factor agent, especially used in the treatment of rheumatoid arthritis, has a good safety profile. One of the most common side-effects of adalimumab is the development of autoantibodies. Despite the induction of autoantibodies, the clinical presentation of immune-mediated complications upon adalimumab therapy, including a lupus-like syndrome, is very rare. We have recently evaluated a new case of adalimumab-induced lupus erythematosus.
