[Aadult-onset Still's disease: new insights from the rheumatologists].

Adult onset Still's disease (AOSD) is a rare polygenic autoinflammatory disease mainly manifesting as high-spiking fever, rash, arthritis/arthralgia, lymphadenopathy, and leukocytosis. More importantly, life threatening macrophage activation syndrome may occur in AOSD patients. Recently, with the development of research in pathogenesis and therapy strategies of biological agents and small molecule targeted drugs, we have new recognition of AOSD. In this commentary, we attempt to place this syndrome in perspective, including data in the past year on pathogenesis, clinical and laboratory features and therapy.
