Etanercept for the treatment of intractable hemophagocytic syndrome with systemic lupus erythematosus

Abstract

A 41-year-old woman presented with continuous fever, and her laboratory data suggested the recrudescence of systemic lupus erythematosus. She was treated with 60 mg/day prednisolone. With a dose reduction of prednisolone, high fever and pancytopenia were observed again. A bone marrow biopsy revealed hemophagocytosis. The effects of steroid pulse therapy, high-dose intravenous immunoglobulin, cyclosporine A, and methotrexate were insufficient. However, after four injections of etanercept (25 mg, twice a week) subcutaneously, her symptoms had completely resolved. In such cases, therapy with etanercept may be effective.
