Masafumi Fukagawa,Keitaro Yokoyama,Fumihiko Koiwa,Masatomo Taniguchi,Tetsuo Shoji,Junichiro James Kazama,Hirotaka Komaba,Ryoichi Ando,Takatoshi Kakuta,Hideki Fujii,Msasaaki Nakayama,Yugo Shibagaki,Seiji Fukumoto,Naohiko Fujii,Motoshi Hattori,Akira Ashida,Kunitoshi Iseki,Takashi Shigematsu,Yusuke Tsukamoto,Yoshiharu Tsubakihara,Tadashi Tomo,Hideki Hirakata,Tadao Akizawa +22 more
TL;DR: CKD-MBD Guideline Working Group, Japanese Society for Dialysis Therapy, and Tadao Akizawa thank the authors for their help and assistance in the development of this guideline.
Journal ArticleDOI
Sevelamer hydrochloride and calcium bicarbonate reduce serum fibroblast growth factor 23 levels in dialysis patients.
Fumihiko Koiwa,Junichiro James Kazama,Akihide Tokumoto,Noritaka Onoda,Hitoshi Kato,Tomoyuki Okada,Tomoko Nii-Kono,Masafumi Fukagawa,Takashi Shigematsu +8 more
TL;DR: Serum FGF23 levels significantly decreased after 4’weeks of the treatment with sevelamer hydrochloride’+ CaCO3 from the pretreatment levels, presumably through inhibiting phosphate load into the intestine.
Journal ArticleDOI
Up-regulation of Cbfa1 and Pit-1 in calcified artery of uraemic rats with severe hyperphosphataemia and secondary hyperparathyroidism
Masahide Mizobuchi,Hiroaki Ogata,Ikuji Hatamura,Fumihiko Koiwa,Fumie Saji,Kazuhiro Shiizaki,Shigeo Negi,Eriko Kinugasa,Akira Ooshima,Shozo Koshikawa,Tadao Akizawa +10 more
TL;DR: Results suggest that medial layer vascular calcification in uraemic rats with severe hyperphosphataemia and SHPT may be caused in part by Cbfa1 and Pit-1.
Journal ArticleDOI
Guidelines for percutaneous ethanol injection therapy of the parathyroid glands in chronic dialysis patients.
Masafumi Fukagawa,Masafumi Kitaoka,Yoshihiro Tominaga,Tadao Akizawa,Takatoshi Kakuta,Noritaka Onoda,Fumihiko Koiwa,Shigeru Yumita +7 more
TL;DR: The 'Guidelines for percutaneous ethanol injection therapy of the parathyroid glands in chronic dialysis patients' proposed by the Japanese Society for Parathyroid Intervention are presented, including indications, techniques, and post-PEIT management.
Journal ArticleDOI
Elastin Degradation Accelerates Phosphate-Induced Mineralization of Vascular Smooth Muscle Cells
Nozomu Hosaka,Masahide Mizobuchi,Hiroaki Ogata,Chiaki Kumata,Fumiko Kondo,Fumihiko Koiwa,Eriko Kinugasa,Tadao Akizawa +7 more
TL;DR: It is suggested that elastin degradation would accelerate or stabilize the process of VSMC transformation, which is induced by high phosphate through the upregulation of TNAP.
