[Infliximab-induced lupus erythematosus in a case of ulcerative colitis].

Infliximab is widely used in the treatment of inflammatory bowel disease, but despite its good clinical efficacy and tolerance, drug-induced autoimmune disorders have been reported as adverse reactions and are a matter of concern. Here we report a patient with ulcerative colitis who developed drug-induced lupus erythematosus after infliximab treatment. While this is a rare complication of infliximab, early diagnosis and successful management are essential.
