[Adult-onset Still's disease : Diagnosis and treatment according to the new S2e guidelines of the German Society of Rheumatology (DGRh)]. / Adultes Still-Syndrom : Diagnostik und Therapie unter Berücksichtigung der neuen DGRh(Deutsche Gesellschaft für Rheumatologie)-S2e-Leitlinie.

ABSTRACT

Adult-onset Still's disease (AOSD) is a rare autoinflammatory disease characterized by intermittent fever and a combination of symptoms, such as an evanescent rash synchronous with fever, arthralgia/arthritis, lymphadenopathy and hepatosplenomegaly. The diagnosis is based on a characteristic constellation of symptoms and the exclusion of infections, hemato-oncological diseases, infectious diseases and alternative rheumatological causes. The systemic inflammatory reaction is reflected by high levels of ferritin and C­reactive protein (CRP). The pharmacological treatment concept includes glucocorticoids often in combination with methotrexate (MTX) and ciclosporine (CSA) for reduction of steroids. The interleukin 1 (IL-1) receptor antagonist anakinra, the IL-1beta antibody canakinumab or an IL­6 receptor blockage with tocilizumab (off label for AOSD) are used where there is no response to MTX or CSA. Anakinra or canakinumab can be used as a primary option in AOSD in cases of moderate and severe disease activity.
