    Abstract:
    A 46-year-old woman was admitted to our hospital because of hemorrhagic tendency. Normal coagulation test results conflicted with the diagnosis of disseminated intravascular coagulation (DIC). Furthermore, we saw no evidence of autoantibodies, including antinuclear antibodies and splenomegaly, and there was no past history of infection or medication. Peripheral blood test showed marked decrease of platelets only. Bone marrow aspiration revealed increased megakaryocytes. Morphology of other blood components was normal. Thus, we diagnosed this case as idiopathic thrombocytopenic purpura (ITP). Administration of prednisolone and an immunosuppressants did not improve symptoms. So patient was temporarily discharged and treated with 6-MP at the outpatient department. She was rehospitalized for liver damage caused by the drug. Patient then developed sepsis from acinetobactor. We administered gabexate mesilate (FOY, 2,000 mg/day) for four days to prevent DIC. Platelet count, which was 1.5 X 10(4)/microliter before FOT administration, began increasing on the second day, reaching 25. 5 X 10(4)/microliter on the fourth. Count rapidly decreased to 2.8 X 10(4)/microliter on the seventh day after administration had been discontinued. Two-time FOY administration after patient's recovery from sepsis led to a definite, similar transient increase in platelet count. As ITP patients with transient increase in platelet count by FOY administration had not been reported, this case is thought to be an interesting case in the pathogenesis and treatment of ITP.
