OBJECTIVES (a) To assess plasma fibrinolytic parameters in patients with rheumatoid arthritis (RA) and to determine whether there are differences between patients with RA alone and those with RA complicated by vasculitis. (b) To determine if patients with RA respond differently to venous occlusion compared with normal subjects and to assess whether such a response differs in patients with RA al...

Rheumatoid arthritis is a clinically and genetically heterogeneous disease. Anti-cyclic citrullinated (anti-CCP) antibodies have a high specificity for rheumatoid arthritis and levels correlate with disease severity. The focus of this study was to examine whether analyzing anti-CCP levels could increase the power of linkage analysis by identifying a more homogeneous subset of rheumatoid arthrit...

The prevalence of clinically evident interstitial lung disease in patients with rheumatoid arthritis is approximately 10%. An additional 33% of undiagnosed patients have interstitial lung abnormalities that can be detected with high-resolution computed tomography. Rheumatoid arthritis-interstitial lung disease patients have three times the risk of death compared to those with rheumatoid arthrit...

We report that sera from healthy controls, patients with ovarian or lung cancer, and patients with rheumatoid arthritis all contain IgM polyclonal rheumatoid factors which recognize antigenic determinants on murine and to a greater extent human immunoglobulin IgG. The major part of this reactivity is directed against conserved, shared antigenic determinants present on both human and murine IgG....

Early diagnosis and treatment of rheumatoid arthritis are associated with improved outcomes but current diagnostic tools such as rheumatoid factor or anti-citrullinated protein antibodies have shown limited sensitivity. In this pilot study we set out to establish a panel of urinary biomarkers associated with rheumatoid arthritis using capillary electrophoresis coupled to mass spectrometry. We c...

We report a 65-year-old man who had repetitive seizures 6 months after receiving etanercept, methotrexate, and prednisolone for rheumatoid arthritis. Mononuclear cells were mildly increased in the cerebrospinal fluid (CSF). Brain magnetic resonance imaging (MRI) showed high intensity along sulci of the frontal and parietal lobes. Brain biopsy revealed lymphocyte and plasma cell infiltration in ...

Rheumatoid synovial fluid macrophages are compatible with synovial membrane fibroblasts in mixed cell culture. They do not appear to have had any immunological experience recognized by homologous rheumatoid blood lymphocytes. The fusion between macrophages which often takes place in cultures of rheumatoid synovial fluid cells seems to be the result of a cell membrane change between contiguous c...

Rheumatoid arthritis is a chronic disease affecting fewer men than women. We systematically reviewed the literature on impact and self-management of rheumatoid arthritis in men. A total of 28 papers were included and grouped into two categories: psychosocial impact of rheumatoid arthritis, and coping and self-management. This review finds gender differences relating to quality of life, work, di...
