Here we investigated the prevalence of A\u03b2 pathology in other instances of iCJD related to dura mater grafts.\n        METHODS: By use of immunohistochemistry for A\u03b2, we investigated seven brains of patients (age range 28\u201363) who succumbed to iCJD after dural grafting, which had been applied by means of neurosurgery between 11 and 25 years before death. For control, we examined a series of 21 brains of age-matched (40\u201363 years) patients with sporadic CJD (sCJD) and an additional series of 81 sCJD cases (55\u201385 years) with the same methods.\n        RESULTS: In five of seven iCJD brains, A\u03b2 was deposited in meningeal vessels as congophilic amyloid angiopathy and brain parenchymal plaques. This was significantly (p &lt;0.001) more frequent than in the age-matched sCJD controls and in the usual sCJD series.\n        CONCLUSIONS: We conclude that congophilic amyloid angiopathy and brain parenchymal A\u03b2 plaques are frequent in iCJD after dural grafting. The presence of A\u03b2 pathology in young individuals is highly unusual and suggests a causal relationship to the dural grafts. Further studies will be needed to elucidate whether such pathology resulted from the seeding of A\u03b2 aggregates from the grafts to host tissues.<\/jats:p>","DOI":"10.4414\/smw.2016.14287","type":"journal-article","created":{"date-parts":[[2016,1,29]],"date-time":"2016-01-29T10:03:57Z","timestamp":1454061837000},"page":"w14287","source":"Crossref","is-referenced-by-count":69,"title":["Amyloid-\u03b2 pathology and cerebral amyloid angiopathy are frequent in iatrogenic Creutzfeldt-Jakob disease after dural grafting"],"prefix":"10.57187","volume":"146","author":[{"given":"Karl","family":"Frontzek","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirjam I.","family":"Lutz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriano","family":"Aguzzi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabor G.","family":"Kovacs","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Herbert","family":"Budka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"36756","published-online":{"date-parts":[[2016,1,17]]},"container-title":["Swiss Medical Weekly"],"original-title":[],"link":[{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/2142\/3162","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/2142\/3163","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/2142\/3162","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T15:02:46Z","timestamp":1788274966000},"score":1,"resource":{"primary":{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/view\/2142"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,1,17]]},"references-count":0,"journal-issue":{"issue":"0304","published-online":{"date-parts":[[2016,1,18]]}},"URL":"https:\/\/doi.org\/10.4414\/smw.2016.14287","relation":{"has-review":[{"id-type":"doi","id":"10.3410\/f.726103360.793513913","asserted-by":"object"}]},"ISSN":["1424-3997"],"issn-type":[{"value":"1424-3997","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,1,17]]}}}
