Abstract

Increased area of the substantia nigra (SN) associated to iron deposition has been proposed as a specific marker for Parkinson's disease (PD). Echogenicity, assessed by transcranial sonography (TCS), has been used to measure such an iron deposition. On the other hand, ferroxidase activity is known to play a role in brain iron metabolism and thus could be involved in increased SN echogenicity of PD patients. The present study was conducted to search for a possible correlation between both markers: TCS of SN and plasma ferroxidase activity. Twenty-one PD patients and 13 healthy volunteers (HV) were included. Mean SN sonographic areas were 0.31 cm² for PD patients and 0.12 cm² for HV (P < 0.001), while plasma ferroxidase activity was reduced in PD patients (P < 0.001). Interestingly, plasma ferroxidase activity was inversely correlated with the SN size by TCS (R² = 0.31), suggesting a relationship between the two markers.

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • A contributing factor to the increased iron accumulation in Parkinson's disease might be increased DMT1 activity or decreased ferroxidase activity of ceruloplasmin, both of which would increase total intracellular iron.

    “A contributing factor to the increased iron accumulation in Parkinson’s disease might be increased DMT1 activity or decreased ferroxidase activity of ceruloplasmin, both of which would increase total intracellular iron, as reported in an animal model of Parkinson’s disease109 and in patients.131–134”

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.
