Adult onset Stills Disease (AOSD) is a systemic inflammatory disease characterized by spiking high fevers, arthritis, and an evanescent rash. Although many patients respond to nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroid, some patients fail to do so or are found to be resistant and require high doses of corticosteroid which induce severe side effects. Recently, treatment with intravenous immunoglobulin (IVIG) has been reported to be effective in patients with AOSD who were refractory to NSAIDs. Here, we report a case of AOSD treated with IVIG with a review of the literature.
