Journal ArticleDOI
Non-invasive detection and differentiation of cardiac amyloidosis using 99mTc-pyrophosphate scintigraphy and 11C-Pittsburgh compound B PET imaging.

TL;DR: All three major types of cardiac amyloidsosis can be detected and differentiated non-invasively by combined use of the two amyloid imaging methods and TTR gene testing.
Journal ArticleDOI
Distribution of amyloidosis subtypes based on tissue biopsy site - Consecutive analysis of 729 patients at a single amyloidosis center in Japan.
Ryuta Abe,Nagaaki Katoh,Yusuke Takahashi,Ken Takasone,Tsuneaki Yoshinaga,Masahide Yazaki,Fuyuki Kametani,Yoshiki Sekijima +7 more
TL;DR: Al was the most common subtype in most biopsy sites except the heart, carpal tunnel, and peripheral nerve, in which ATTR was more common, and amyloid typing must be pursued, no matter the site from where biopsy was obtained.
Journal ArticleDOI
Spinal form cerebrotendinous xanthomatosis patient with long spinal cord lesion
Ryuta Abe,Yoshiki Sekijima,Tomomi Kinoshita,Tsuneaki Yoshinaga,Shingo Koyama,Takeo Kato,Shu-ichi Ikeda +6 more
TL;DR: Spinal form CTX should be considered in the differential diagnosis of cryptogenic myelopathy, especially in patients with a long spinal cord lesion, as treatment with chenodeoxycholic acid and/or competitive inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase reverse the metabolic derangement and prevent the neurologiccal dysfunction.
Journal ArticleDOI
A case of novel amyloidosis: glucagon-derived amyloid deposition associated with pancreatic neuroendocrine tumour.
Shojiro Ichimata,Shojiro Ichimata,Nagaaki Katoh,Ryuta Abe,Tsuneaki Yoshinaga,Fuyuki Kametani,Masahide Yazaki,Takeshi Uehara,Yoshiki Sekijima +8 more
TL;DR: A case of localised amyloid deposition in association with neuroendocrine tumours, such as medullary thyroid carcinoma and pituitary prolactinoma is reported.
Journal ArticleDOI
An autopsy case of amyloid tubulopathy exhibiting characteristic spheroid-type deposition.
Shojiro Ichimata,Yukiko Hata,Ryuta Abe,Tsuneaki Yoshinaga,Nagaaki Katoh,Fuyuki Kametani,Masahide Yazaki,Yoshiki Sekijima,Takashi Ehara,Naoki Nishida +9 more
TL;DR: An 84-year-old woman with a history of haemodialysis for renal failure from approximately 1 year before death, autopsy revealed numerous spheroid-type amyloid deposits in the kidney that were observed mainly in the interstitium but not the glomeruli and vessels.
