Abstract

Background: The pattern and role of microglial activation in multiple system atrophy is largely unclear. The objective of this study was to use [ 11 C] (R) ‐PK11195 PET to determine the extent and correlation of activated microglia with clinical parameters in MSA patients. Methods: Fourteen patients with the parkinsonian phenotype of MSA (MSA‐P) with a mean disease duration of 2.9 years (range 2‐5 years) were examined with [ 11 C] (R) ‐PK11195 PET and compared with 10 healthy controls. Results: Patients with the parkinsonian phenotype of MSA showed a significant ( P ≤ 0.01) mean increase in binding potentials compared with healthy controls in the caudate nucleus, putamen, pallidum, precentral gyrus, orbitofrontal cortex, presubgenual anterior cingulate cortex, and the superior parietal gyrus. No correlations between binding potentials and clinical parameters were found. Conclusions: In early clinical stages of the parkinsonian phenotype of MSA, there is widespread microglial activation as a marker of neuroinflammatory changes without correlation to clinical parameters in our patient population. © 2019 The Authors.

  • Widespread microglial activation occurs early in the clinical stage of MSA.

    “suggesting widespread microglial activation occurs early in the clinical stage of MSA.”
  • PET imaging demonstrated microglial activation in the brains of patients with MSA.

    “PET imaging also demonstrated microglial activation in the brains of patients with MSA.”
  • In a [11C](R)-PK11195 PET study, MSA-P patients had significantly higher binding potentials in the precentral gyrus, caudate nucleus, putamen, pallidum, orbitofrontal cortex, superior parietal gyrus and presubgenual anterior cingulate cortex than controls.

    “it was found that MSA-P patients had significantly higher binding potentials in the precentral gyrus, caudate nucleus, putamen, pallidum, orbitofrontal cortex, superior parietal gyrus and presubgenual anterior cingulate cortex than controls.286”
  • According to pathological studies and PET imaging of MSA brains, microglial activation and neuroinflammation constitute important features of MSA.

    “But according to pathological studies and PET imaging of MSA brains, microglial activation and neuroinflammation constitute important features of MSA.283–287”

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.
