[Reactive hemophagocytic syndrome responded to combination chemotherapy with steroid pulse therapy].

A 66-year-old male was admitted to our hospital because of persistent fever. Laboratory data revealed leukopenia, thrombocytopenia, marked elevation of serum lactic acid dehydrogenase and ferritin levels, as well as disseminated intravascular coagulophathy (DIC). Bone marrow aspiration showed increased numbers of mature histiocytes with hemophagocytosis and a diagnosis of reactive hemophagocytic syndrome was made. In the broad spectrum of this syndrome, we suspected virus-associated hemophagocytic syndrome (VAHS) but no causative viral infection was detected. Since DIC is known to be a poor prognostic factor, he was given combination chemotherapy containing VP-16 in addition to pulse therapy of methylprednisolone. He completely recovered after the treatment. Chemotherapy is one option in the treatment of adult onset reactive hemophagocytic syndrome.
