[Case report of systemic lupus erythematosus patient with hemophagocytic syndrome, treated with plasma exchange, with specific reference to clinical profile and serum cytokine levels].
A 42-year-old woman was diagnosed as systemic lupus erythematosus (SLE), because of the findings of polyarthritis, leukopenia, positive antinuclear antibody, and positive anti DNA antibody. She was treated with predonisolone (PSL) at 10 mg per day. She was admitted to our hospital on October 2000 because of spiking high fever, skin eruption, and lymph node swelling. Since her illness of SLE was considered to be worsening, high dose of corticosteroids were given. However, high fever persisted and liver dysfunction was developed with increased serum ferritin. Her bone marrow smear showed hemophagocytosis. We made a diagnosis of hemophagocytic syndrome (HPS) complicated by disseminated intravascular coagulation (DIC). HPS was thought to be induced by viral infection, even though causative viral infection was not detected. Her general condition worsened with persistent high fever and liver dysfunction. Plasma exchange was carried for two consecutive days, followed by cyclosporine A and lipo-dexamethasone, which improved her fever rapidly. Her general condition gradually improved. Serum levels of ferritin, soluble interleukin 2 receptor (sIL 2-R), interferon-gamma and interleukin 6 decreased associated with improvements of her clinical condition. We thought plasma exchange could be effective to decrease serum levels of cytokine, which was suggested to be the pathogenic to HPS. However serum levels of IFN-gamma and IL 6 after plasma exchange did not change in this case. Further studies are required to confirm the effects of plasma exchange for HPS.
