Rheumatoid factor in congenital syphilis.
The rheumatoid factor (RF) latex test was evaluated as a test for congenital syphilis. High risk newborns of mothers with untreated or inadequately treated syphilis were studied. The asymptomatic infants were followed up for between 3 and 4 months (or longer if the VDRL test was positive). The overall performance of the RF latex test was better than that of the other tests studied, even though ...
متن کاملIgM rheumatoid factor removal and performance of the FTA-ABS (IgM) test in congenital syphilis.
OBJECTIVE To determine the performance of the FTA-ABS (IgM) test in congenital syphilis after eliminating interference by IgM rheumatoid factor (RF) and preventing competitive inhibition by IgG. DESIGN The FTA-ABS (IgM) test was carried out before and after RF removal (achieved by immunoprecipitation of the IgG) in infants with congenital syphilis and controls.

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...
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...
