[A case of systemic lupus erythematosus associated with thrombotic thrombocytopenic purpura and hemophagocytic syndrome].

Abstract

THE CASE:

A 44-year-old female. Developed polyarthralgia in August 2002. The patient was diagnosed with systemic lupus erythematosus (SLE) in November, due to polyarthralgia, leukopenia, anti ds-DNA antibody positive, antinuclear antibody positive, and false positive serologic test for syphilis. Hypocomplementemia continued even after the steroid treatment was conducted with insufficient control. In November 2003, ran fever and observed polyarthralgia. In December, gross hematuria and purpura appeared. The patient was hospitalized on December 25. Thrombotic thrombocytopenic purpura (TTP) was suspected from the emergence of fragmented red cells, hemolysis, thrombocytopenic purpura, headache, renal dysfunction and fever. As hemophagocytic syndrome (HPS) was suspected from hyper-ferritinemia, bone marrow aspiration was conducted. Macrophage confirmed hemophagocytic image and the patient was diagnosed with HPS complication. Methylprednisolone pulse therapy was conducted for three days, followed by the administration of prednisolone 60 mg. Plasma exchange therapy was also conducted from the first day of hospitalization. Recurrence of TTP after plasma exchange therapy, but it improved by additional plasma exchange. Low vWF-CP (ADAMTS-13) activity was observed in this case, and anti-vWF-CP antibody was positive. TTP and HPS are both critical intractable complications of SLE. Bearing in mind the possibility of simultaneous complication of both symptoms, prompt diagnosis is crucial for life-saving.
