Topic: Amyloid, tau and blood-test diagnosis

Sowohl in der Tau- als auch in der Amyloid-PET-Bildgebung zeigte die Quantifizierung eine gute bis exzellente Vorhersage der visuellen Beurteilung (Tau: AUC=0,86, p<0,0001; Amyloid: AUC=0,99, p<0,0001). Ebenso signifikant war die Korrelation zwischen CLs und Aß42/40-CSF (r=-0,69, p<0,001). Ähnlich korrelierten CLs und Tau-PET SUVRs (r=0,56, p<0,001), wobei sich insbesondere im Bereich niedriger Werte eine gute Übereinstimmung zeigte. Die ermittelten Grenzwerte betrugen für CLs 35,4 (Se=0,98, Sp=0,99) und für Tau-PET SUVRs 1,29 (Se=0,71, Sp=0,95). Schlussfolgerungen/ Die Ergebnisse bestätigen die Zuverlässigkeit und klinische Anwendbarkeit der quantitativen Amyloid- und Tau-PET-Bildgebung im klinischen Routinekontext. Die beobachtete Verteilung zwischen SUVRs und CLs stützt die bisherige Annahme, dass die Tau-Last, verglichen mit Amyloid, erst in einem späteren Krankheitsstadium zunimmt. Die ermittelten CL- und SUVR-Grenzwerte bieten eine gute Grundlage für einen zukünftigen Diagnosealgorithmus für AD-Patienten, die von einer potentiellen Antikörper-Therapie profitieren könnten.

Key findings

Why it matters

This study compared quantitative amyloid and tau PET measures with visual reading and spinal fluid biomarkers in a real-world clinical setting, finding good agreement and establishing cutoff values. It is a diagnostic validation study and does not test any treatment, cure, or prevention.

Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 31 of the 96 points we could judge it on, which is 32 out of 100.
