[Creutzfeldt-Jakob disease in a dura transplant recipient: first observation in Austria].
Dura mater grafts can lead to Creutz-feldt-Jakob disease (CJD) as late complication (dura-CJD). So far 61 dura-CJD cases have been described worldwide. We report here the first dura-CJD case in Austria. A 50-year-old man had a traumatic open frontobasal skull fracture with tearing of dura mater in 1977. Reconstructive surgery used Lyodura (braun Melsungen AG, BRD). Lyodura was derived from pooled cadaveric dura. Ten years after the dural transplantation, the patient developed gait ataxia, paresthesia of both legs, myoclonus and visual disturbance. CT was unremarkable. EEG showed diffuse unspecific changes. The patient died 5 months after onset of disease. Neuropathological examination showed typical histopathology of CJD. Immunocytochemistry detected typical type prion protein (PrP) deposits and scattered PrP plaques in cerebral and cerebellar cortex, basal ganglia and spinal cord. Cerebellar white matter contained numerous PrP miniplaques. This pattern is unusual for sporadic CJD, but is similar to that in CJD after human growth hormone treatment. In our patient and 13/19 earlier described cases with dural graft covering the cerebrum ("central inoculation"), cerebellar disturbance was the initial symptom. Therefore, cerebellar signs are characteristic as initial symptoms in iatrogenic CJD, irrespective of central (cerebral dura mater graft) or peripheral inoculation (e.g., human growth hormone treatment). These data do not support the hypothesis that primary cerebellar symptoms in iatrogenic CJD after peripheral inoculation reflect migration of the infectious agent from the periphery via spinal cord and cerebellum to the cerebrum.
