[Progressive multifocal leukoencephalopathy in Wegener's granulomatosis in relation to therapy with cyclosporin A].
A female patient with Wegener's granulomatosis developed severe bone marrow depression after two years treatment with cyclophosphamide. Corticosteroids alone could not sufficiently suppress disease activity, therefore additive therapy with Cyclosporin A was started. Four weeks later the patient developed a central nervous system disorder with affective disturbances and progressive somnolence. However, inspite of intensive diagnostic procedures, no definite diagnosis could be established. After another two months she died. Post-mortem-examination showed progressive multifocal leukoencephalopathy. An association between immunosuppressive therapy and reactivation of JC-Virus is suggested.
