Etanercept induced organizing pneumonia in a patient with rheumatoid arthritis

초록

TNF inhibitors are being used in a rapidly expanding number of rheumatoid arthritis (RA) patients due to their effectiveness and acceptable safety profiles. To date, concerns regarding the adverse effects of TNF inhibitors have focused on infections, hematologic malignancies, and demyelinating disorders. Recently, the development of autoantibodies and other autoimmunity has been increasingly reported. Here, we describe a 36-year-old RA patient in whom organizing pneumonia and systemic lupus erythematosus were detected during etanercept treatment.
