Abstract
Adult-onset Still's disease (AOSD) is characterized by high spiking fever, evanescent rash, and arthritis. However, AOSD rarely presents with severe acute kidney injury (AKI). We herein present the case of a 56-year-old woman with new-onset AOSD who rapidly developed AKI. A physical examination and laboratory data revealed spiking fever, evanescent rash, thrombocytopenia, hyperferritinemia, and azotemia. The patient was diagnosed with AOSD complicated by AKI and macrophage activation syndrome. Treatment with high-dose steroids, hemodialysis, and plasma exchange successfully resolved her AKI. In this report, we review previously published reports on AOSD accompanied by AKI and discuss this rare complication in AOSD.
