Abstract
We report a 16-year-old female case of intractable adult-onset Still's disease accompanied by macrophage activation syndrome, who went into full remission after switching from infliximab to etanercept. Although the disease promptly relapsed when etanercept was discontinued, she again responded fully upon the reintroduction of etanercept. Furthermore, the effect of etanercept was apparently enhanced by combining it with a sufficient dose of methotrexate. This combination therapy should be considered as one of treatment options for the disease.
