Abstract:
Prion diseases include scrapie, BSE and CWD in animals, and spontaneous, familiar and infectious Creutzfeldt-Jakob disease(CJD) in human. Infectious prion diseases include kuru, variant CJD and iatrogenic CJD. CJD has been transmitted from human to human by contaminated cadaveric dura mater grafts and by cadaveric pituitary hormones. To date, CJD associated with dura mater grafts, reaching 156 cases, has been reported in 17 countries. More 2/3 of cases have been reported in Japan. Nationwide survey and recent information documented 105 dura-related cases during the period between 1979 and 2003. At least 91 cases received same brand of dura mater by a single German company. Age at disease onset in cases with dura-related CJD was younger (54.2 +/- 14.2 years) than sporadic CJD (64 +/- 10 years). Two groups of dura-related CJD are manifest in clinical course and pathological characteristics, such as rapidly progressive group and slowly progressive. Rapidly group was similar to cases with classical CJD in clinical features and shot duration to death from onset. Slowly progressive group developed akinetic mutism longer than 1 year, and characterized by florid plaques in the brain (Kitamoto).
Insights
Creutzfeldt-Jakob disease (CJD) can transmit via contaminated dura mater grafts, with over 100 cases linked to a specific German brand. Dura-related CJD cases present younger and show distinct clinical and pathological features.
Area of Science:
- Neurology
- Infectious Diseases
- Pathology
Context:
- Prion diseases, including Creutzfeldt-Jakob disease (CJD), affect both animals and humans.
- Human CJD can be transmitted through medical procedures involving contaminated tissues, such as dura mater grafts and pituitary hormones.
- Iatrogenic CJD cases linked to dura mater grafts have been reported globally, with a significant concentration in Japan.
Purpose:
- To analyze the epidemiology, clinical presentation, and pathological characteristics of dura mater graft-associated Creutzfeldt-Jakob disease (CJD).
- To identify specific risk factors and patterns associated with dura mater graft transmission of CJD.
- To differentiate between clinical and pathological subtypes of dura mater graft-associated CJD.
Summary:
- A total of 156 dura mater graft-associated CJD cases have been reported across 17 countries, with over two-thirds originating in Japan.
- A nationwide survey identified 105 dura-related CJD cases between 1979 and 2003, with 91 linked to a single German dura mater brand.
- Dura-related CJD cases exhibit an earlier onset (mean age 54.2 years) compared to sporadic CJD (mean age 64 years) and present in two distinct forms: rapidly progressive and slowly progressive.
Impact:
- Highlights the risk of prion disease transmission through surgical materials.
- Informs public health strategies for preventing iatrogenic Creutzfeldt-Jakob disease.
- Contributes to understanding the heterogeneity of CJD pathogenesis and clinical manifestations.
