Rheumatoid factor tests in the diagnosis and prediction of rheumatoid arthritis.
Four assays of rheumatoid factor (RF) have been measured on serum from 213 individuals from 13 families containing at least two sufferers from classical or definite rheumatoid arthritis (RA). Families were not uniformly RF positive or negative, and there was no evidence that non-RA RF positivity was inherited. Four individuals developed definite RA over a two year period, showing that the famil...
متن کاملRheumatoid Arthritis: Early diagnosis and treatment outcomes
Rheumatoid arthritis (RA) is an inflammatory progressive disease which in the absence of appropriate treatment can lead to joint destruction and disability. Prognosis of RA may be predicted based on the presence of some clinical and laboratory evidences.New criteria for classification of RA provides opportunity for earlier treatment. Initiation of treatment particularly by combination of DMARDs...
متن کاملComparative Measurement of Rheumatoid Factor in Serum and Synovial Fluid of Rheumatoid Arthritis Patients by ELISA and Latex-Agglutination Test
Rheumatoid factors (RF) are autoantibodies with specificity for the Fc portion of human IgG. Production of RF is a characteristic feature of rheumatoid arthritis (RA) and is detectable in high titer in about 90% of these patients. In this study, we measured total IgM, IgA, IgMRF and IgARF in serum and synovial fluid of 45 RA patients by ELISA and the results were compared with those obtained b...
متن کاملDifferential Expression of Rheumatoid Factor-Associated Cross-Reactive Idiotypes in Iranian Seropositive and Seronegative Patients with Rheumatoid Arthritis
High levels of rheumatoid factors (RF) are detectable in serum of the majority of patients with rheumatoid arthritis (RA), but 5-10% of patients remain seronegative (SN). Despite clinical and genetic similarities between these two subsets of RA, it has been proposed that they may be regarded as distinct clinical entities. Methods: In the present study a panel of monoclonal antibodies (mAb) rec...
