Abstract

Objective Hemorrhage related to cerebral amyloid angiopathy (CAA) appears to occur through a multistep pathway that includes deposition of beta-amyloid in cerebral vessels and specific vasculopathic changes in the amyloid-laden vessels, such as cracking of the vessel wall. Recent reports suggest a positive association between CAA-related hemorrhage and both the apolipoprotein E (APOE) epsilon4 allele and, unexpectedly, the APOE epsilon2 allele. Unlike APOE epsilon4, APOE epsilon2 does not appear to act through increased beta-amyloid deposition. We therefore sought to determine whether it might specifically accelerate the second step in this pathway, that is, development of the vasculopathic changes that lead to hemorrhage. Methods To determine the role of APOE in development of vasculopathic changes, we compared APOE genotypes in two groups of postmortem brains: 52 brains with complete amyloid replacement of vessel walls but without vasculopathic changes, and 23 brains with complete amyloid replacement of vessels with the accompanying changes of cracking of the vessel wall and paravascular leaking of blood. Results Frequency of APOE epsilon2 was significantly greater in the group with vasculopathy (0.09) than the group without (0.01, p = 0.03). The groups did not differ in mean age or extent of neuritic plaques. Analysis of a clinical series of patients with CAA-related hemorrhage confirmed an overrepresentation of APOE epsilon2 as well as an association between this allele a…

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Human studies have linked APOE2 to greater CAA severity in some cohorts, and to CAA-related vasculopathic changes and hemorrhagic complications.

    “However, human studies have linked APOE2 to greater CAA severity in some cohorts 52 , and to CAA-related vasculopathic changes and hemorrhagic complications 53,54 .”
  • APOEε2/ε4 individuals have a particularly high risk of intracerebral lobar haemorrhage in the presence of cerebral amyloid angiopathy, possibly because the APOEε2 allele has been associated with fibrinoid necrosis of the vessel wall.

    “Of note, APOEε2/ε4 individuals have a particularly high risk of intracerebral lobar haemorrhage in the presence of CAA50, possibly because the APOEε2 allele has been associated with fibrinoid necrosis of the vessel wall56,57.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
