TL;DR: ACPA-negative RA includes two genetically distinct subsets according to RF positivity in Japan, which display different associations with HLA-DRB1 and DR14 and the Hla-DR8 homozygote.
Journal ArticleDOI
Risk factors associated with the occurrence of hip fracture in Japanese patients with rheumatoid arthritis: a prospective observational cohort study
TL;DR: High J-HAQ disability score, advanced age, history of TKR, and low BMI appear to be associated with the occurrence of hip fractures in Japanese RA patients.
Journal ArticleDOI
Vaccination against seasonal influenza is effective in Japanese patients with rheumatoid arthritis enrolled in a large observational cohort
Tsuyoshi Kobashigawa,A Nakajima,Atsuo Taniguchi,E Inoue,E Tanaka,Shigeki Momohara,H. Yamanaka +6 more
TL;DR: Influenza vaccination was effective in patients with RA regardless of disease activity or treatment and there were no associations between influenza attacks and RA disease activity, treatment with methotrexate (MTX) or corticosteroids.
Journal ArticleDOI
Failure to confirm association between PDCD1 polymorphisms and rheumatoid arthritis in a Japanese population
Takuji Iwamoto,Katsunori Ikari,Eisuke Inoue,Yoshiaki Toyama,Masako Hara,Hisashi Yamanaka,Taisuke Tomatsu,Shigeki Momohara,Naoyuki Kamatani +8 more
TL;DR: In this article, the association of PDCD1 with RA using a large series of Japanese RA patients and population-based controls was analyzed using a TaqMan fluorogenic 5′ nuclease assay.
Journal ArticleDOI

TL;DR: The risk of serious respiratory infection in the TCZ cohort was approximately double that in the IORRA subsample cohort after standardizing for corticosteroid use, pre-existing pulmonary involvement, or disease activity, comparable to the risk reported when tumor necrosis factor (TNF) inhibitors are used.
