Rheumatoid arthritis : Looking Beyond Rheumatoid Factor

762 IntroductIon Rheumatoid arthritis (RA) is a chronic crippling disease that causes significant morbidity and even mortality. The etiology is not known and hence the diagnosis is based on the typical clinical picture of inflammatory symmetrical polyarthritis supported by imaging and serological investigations. Among the serological investigations, rheumatoid factor (RF) is the most widely use...

Differential 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...

Rheumatoid factor in Schizophrenia

We studied 30 consecutive female schizophrenics diagnosed on Research Diagnostic Criteria (Spitzer et al 1975) and were age and sex matched with 30 normal healthy females comprising the control group. The relevant blood (hemogram, blood sugar and urea serum proteins etc), urine, stool, chest and skull skiagrams were done to rule out any physical illness in study and control Group. The presence ...

Comparative 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...
