Rheumatoid arthritis is a common autoimmune disease characterized by chronic inflammation. We report a meta-analysis of genome-wide association studies (GWAS) in a Japanese population including 4,074 individuals with rheumatoid arthritis (cases) and 16,891 controls, followed by a replication in 5,277 rheumatoid arthritis cases and 21,684 controls. Our study(More)
INTRODUCTION Rheumatoid arthritis (RA) is a systemic, chronic inflammatory disease influenced by both genetic and environmental factors, leading to joint destruction and functional impairment. Recently, a large-scaled GWAS meta-analysis using more than 37,000 Japanese samples were conducted and 13 RA susceptibility loci were identified. However, it is not(More)
Though excellent clinical results have been reported for total joint arthroplasty (TJA) in rheumatoid arthritis (RA) patients, the longitudinal effects of TJA on pain, physical function, and health-related quality of life in RA patients remain unknown. This study aimed to assess changes in disease activity and health-related quality of life after TJA in(More)
We developed a novel model of onychomycosis in which we observed fungi in the deep layer of the nail, and we used the model to evaluate the efficacy of two topical antifungal drugs. To establish an experimental, in vivo model of onychomycosis, we applied Trichophyton mentagrophytes TIMM2789 to the nails of the hind limbs of rabbits that underwent steroid(More)
OBJECTIVE This retrospective study was designed to evaluate the outcomes of four different surgical reconstructions for extensor tendon ruptures in ulnar three fingers in 48 patients with rheumatoid arthritis. METHODS The following four techniques were performed; palmaris longus tendon grafting (PL group; n = 9), extensor indicis proprius (EIP) tendon(More)
When dealing with patients with severe atopic dermatitis (AD), inpatient treatment is useful for alleviating skin symptoms in short periods of time. We previously found that many severe AD patients had low serum cortisol levels at admission. The present study was undertaken to evaluate the efficacy of inpatient treatment in 29 adults with AD through(More)
A 70-year-old man with a 3-month history of low back pain was admitted to our hospital due to difficulty in walking with pain and swelling in the right knee joint in September 2004. On admission, physical examination revealed a 15 cm mass with fever in the right knee joint. The superficial lymph nodes were not enlarged. The erythrocyte sedimentation rate(More)
OBJECTIVE Anti-citrullinated protein antibodies (ACPAs) are highly specific to rheumatoid arthritis (RA), and strong associations between HLA-DRB1 alleles and ACPA levels have been detected in RA patients. We undertook this study to elucidate the associations between particular amino acid positions in HLA-DRB1 and ACPA levels in patients with RA. METHODS(More)
