Motohisa Yamamoto,Hiroki Takahashi,Tetsuya Tabeya,Chisako Suzuki,Yasuyoshi Naishiro,Keisuke Ishigami,Hidetaka Yajima,Yui Shimizu,Mikiko Obara,Hiroyuki Yamamoto,Tetsuo Himi,Kohzoh Imai,Yasuhisa Shinomura +12 more
TL;DR: The clinical characteristics of IgG4-RD patients who had cancer that was observed upon the initial diagnosis or that occurred during an average follow-up period of 3.1 years were analyzed and the standardized incidence ratio (SIR) for malignancies in IgG 4-RD was higher than that for the general population.
Journal ArticleDOI
Association of Fusobacterium nucleatum with immunity and molecular alterations in colorectal cancer
Katsuhiko Nosho,Yasutaka Sukawa,Yasushi Adachi,Miki Ito,Kei Mitsuhashi,Hiroyoshi Kurihara,Shinichi Kanno,Itaru Yamamoto,Keisuke Ishigami,Hisayoshi Igarashi,Reo Maruyama,Kohzoh Imai,Hiroyuki Yamamoto,Yasuhisa Shinomura +13 more
TL;DR: Emerging evidence may provide insights for strategies to target microbiota, immune cells and tumor molecular alterations for colorectal cancer prevention and treatment.
Journal ArticleDOI
Value of serum IgG4 in the diagnosis of IgG4-related disease and in differentiation from rheumatic diseases and other diseases
Motohisa Yamamoto,Tetsuya Tabeya,Yasuyoshi Naishiro,Hidetaka Yajima,Keisuke Ishigami,Yui Shimizu,Mikiko Obara,Chisako Suzuki,Kentaro Yamashita,Hiroyuki Yamamoto,Toshiaki Hayashi,Shigeru Sasaki,Toshiaki Sugaya,Tadao Ishida,Kenichi Takano,Tetsuo Himi,Yasuo Suzuki,Norihiro Nishimoto,Saho Honda,Hiroki Takahashi,Kohzoh Imai,Kohzoh Imai,Yasuhisa Shinomura +22 more
TL;DR: The aim of this work was to re-evaluate the usual cut-off value in AIP (135 mg/dL) that is used to diagnose whole IgG4-RD in the setting of a rheumatic clinic by measuring serum Igg4 levels in IgG 4-RD and various disorders.
Journal ArticleDOI
Everyday clinical practice in IgG4-related dacryoadenitis and/or sialadenitis: results from the SMART database.
Motohisa Yamamoto,Hidetaka Yajima,Hiroki Takahashi,Yoshihiro Yokoyama,Keisuke Ishigami,Yui Shimizu,Tetsuya Tabeya,Chisako Suzuki,Yasuyoshi Naishiro,Kenichi Takano,Ken Yamashita,Masato Hashimoto,Yoshiko Keira,Saho Honda,Takashi Abe,Yasuo Suzuki,Masaya Mukai,Tetsuo Himi,Tadashi Hasegawa,Kohzoh Imai,Yasuhisa Shinomura +20 more
TL;DR: The Sapporo Medical University and Related Institutes Database for Investigation and Best Treatments of IgG4-related Disease (SMART) is established to clarify the clinical features of Igg4-RD and provide useful information for clinicians.
Journal ArticleDOI
Necessity of early intervention for IgG4-related disease—delayed treatment induces fibrosis progression
Yui Shimizu,Motohisa Yamamoto,Yasuyoshi Naishiro,Gohta Sudoh,Keisuke Ishigami,Hidetaka Yajima,Tetsuya Tabeya,Mikiko Matsui,Chisako Suzuki,Hiroki Takahashi,Nobuhiko Seki,Tetsuo Himi,Ken Yamashita,Hiroko Noguchi,Tadashi Hasegawa,Yasuo Suzuki,Saho Honda,Takashi Abe,Kohzoh Imai,Yasuhisa Shinomura +19 more
TL;DR: Salivary secretion can be improved even in cases with lower levels of salivary gland secretion before treatment in IgG4-RD, but improvements in the amount of salIVary secretion decrease with histological changes with delayed therapeutic intervention, suggesting that early intervention is needed to improve outcomes in patients with IgG 4-MD.
