title: [Successful treatment with vincristine for an elderly patient with idiopathic thrombocytopenic purpura].
abstract: A 77-year-old female was referred to our hospital in March 1991 because of a severe bleeding tendency. Her blood count on admission was as follows: Hb 7.5 g/dl, WBC 4.6 x 10(9)/l with normal differentiation and platelet 2 x 10(9)/l. One month prior to admission, her blood count was normal. Initially, acute idiopathic thrombocytopenic purpura (ITP) was suspected, because of the acute onset of the bleeding tendency and thrombocytopenia. High dose intravenous immunoglobulin (400 mg/kg/day for 5 days) and bolus methylprednisolone (1 g/day for 3 days then tapered) were administered, starting March 13. Her platelet count had increased immediately on March 20 to 40 x 10(9)/l. However, platelet count decreased to 4 x 10(9)/l in the following two weeks. Her clinical course differed from that of typical acute ITP. Because the treatment with prednisolone was not effective, it was changed to intravenous infusion of vincristine (VCR) at a weekly dose of 1 mg for 6 weeks. The treatment was extremely effective, and her platelet count reached over 200 x 10(9)/l. The treatment was discontinued. Three weeks later, her platelet count decreased to 15 x 10(9)/l, the administration of VCR was resumed, and her platelet count recovered again. Throughout her clinical course, no side effect of VCR was noticed except for mild hypesthesia of the fingertips. VCR therapy was considered to be an useful treatment in elderly patients with ITP.
