| 内容記述 | Objectives: Our previous studies demonstrated that 18F-PM-PBB3 (18F-APN-1607) uptake may reflect characteristic distributions of tau pathologies in 4-repeat tauopathies including progressive supranuclear palsy (PSP). The present study aimed to investigate the association among 18F-PM-PBB3 uptake, neurodegenerative biomarker level, and clinical symptoms in PSP with Richardson syndrome (PSP-RS) patients. Methods: 21 patients with probable PSP-RS underwent PET scans with 18F-PM-PBB3 and 11C-PiB for estimating regional tau and Aβ deposition. Plasma neurofilament light chain (NfL) levels were also checked as a neurodegenerative biomarker. Parametric 18F-PM-PBB3- and 11C-PiB- images were generated by voxel-based calculation of the standardized uptake value ratio (SUVR) to the cerebellar cortex. Three patients, who were diagnosed as amyloid-positive by visual assessment of 11C-PiB SUVR image, were excluded. Finally, the other 18 PiB-negative PSP-RS patients were included for further analyses. Regional 18F-PM-PBB3 SUVR was estimated in dentate, midbrain, subthalamus, striatum, pre- and post-central gyri in addition to PSP tau PET meta-ROI. We assessed Pearson’s correlation of regional 18F-PM-PBB3 SUVR with plasma NfL levels and motor severity assessed by PSP rating scale. Results: Plasma NfL levels showed positive correlation with 18F-PM-PBB3 SUVR in striatum, pre- and post-central gyri as well as PSP tau PET meta-ROI (r = 0.77, 0.98, 0.95, and 0.78; p < 0.05, followed by Bonferroni correction), and a trend toward significance in midbrain and dentate (r = 0.68 and 0.51; p = 0.008 and 0.043, without multiple comparison). PSP rating scale score positively correlated with plasma NFL (r = 0.73; p < 0.01, followed by Bonferroni correction), and there were trends towards significance between PSP rating scale and 18F-PM-PBB3 SUVR in midbrain and PSP tau PET meta-ROI (r = 0.66 and 0.65; p = 0.01 and 0.03, without multiple comparison). Conclusions: Accumulations of PM-PBB3 may reflect neurotoxic tau pathologies in PSP-RS, in tight association with clinical symptoms. |
