PG - e0918 LID - 10.1002/rcr2.918 [doi] LID - e0918 AB - A 69-year-old woman with rheumatoid arthritis, using immunosuppressants, including etanercept-a tumour necrosis factor (TNF)-alpha antagonist-was referred to our hospital with fever and fatigue. Chest computed tomography revealed cavities in the left upper lobe. As Mycobacterium intracellulare infection was diagnosed, all immunosuppressants were discontinued, and treatment with anti-nontuberculous Mycobacterium drugs was initiated. However, her condition worsened paradoxically. We diagnosed immune reconstitution inflammatory syndrome (IRIS) resulting from the discontinuation of the TNF-alpha antagonist. Her condition improved with prednisolone treatment. IRIS is generally observed during HIV treatment, but a good understanding of immunosuppressant-related non-HIV IRIS is needed.
