Abstract

Cerebrospinal fluid (CSF) measures of phosphorylated-tau (P-tau) 231 and P-tau181 are two biomarkers for the identification of tau pathology as related to Alzheimer’s disease (AD). While both are pathologically validated, their relative diagnostic performances are not well known. This cross-sectional diagnostic study of 87 normal (NL) subjects and 28 AD subjects compared CSF P-tau231 with CSF P-tau181. Logistic regression modeling demonstrated that the P-tau231 was superior to the P-tau181 in the diagnostic classifications. At a fixed 85% sensitivity cutoff, the ROC analysis shows that P-tau231 has greater overall specificity than P-tau181. While both P-tau analytes demonstrated equivalent negative predictive accuracies, P-tau231 yielded significantly fewer false positives. Moreover, P-tau231, but not P-tau181, demonstrated sensitivity to the E4 genotype. A postmortem validation with 9 AD subjects confirmed the superiority of the CSF P-tau231 specificity. This study suggests that P-tau231 has the potential to improve the CSF tau biomarker diagnosis of AD.

  • CSF p-tau231 has been widely reported as a biomarker to detect AD at both the MCI and dementia stages, but often it has been concluded that these changes are not different from CSF p-tau181 when directly compared.

    “CSF p-tau231 has been widely reported as a biomarker to detect AD at both the MCI and dementia stages of disease11,49, 50, 51, 52, 53 but often it has been concluded these changes are not different from CSF p-tau181 when directly compared.54”

    The Introduction reports that one meta-analysis found P-tau181 and P-tau231 comparably good for AD diagnosis, supporting the claim that a direct comparison has found them similar. But it does not establish that this was often concluded, and the paper’s Discussion concludes that P-tau231 was superior at separating AD patients from normal controls.

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.
