in  this  study  we  determined  the  frequency,  sensitivity  and  specificity  of  anti  cyclic citrullinated peptides (anti-ccp) igg antibody, total rheumatoid factor (rf-t), and rf isotypes in iranian patients with rheumatoid arthritis (ra) and their association with age, clinical and serological parameters. anti-ccp and rf-t and rf isotypes level were measured in 418 patients and 399 healt...

  Rheumatoid Arthritis (RA) is a systemic autoimmune disease. Production of Rheumatoid Factor(RF) is a characteristic feature of the majority RA patients. Previous studies showed there are differences between seropositive-RA(SP-RA) and seronegative-RA(SN-RA), regarding clinical manifestations.   In this study the level of CRP was measured in serum and synovial fluid of 45 RA patients by latex a...

Serum samples from patients with seropositive rheumatoid arthritis contain an inhibitor of complement mediated inhibition of immune precipitation (CMIP). This inhibitory effect can be produced by the addition of either purified monoclonal or polyclonal IgM rheumatoid factor (RF) to human serum. The specificity of the rheumatoid factor influences the degree of inhibition, and when precipitation ...

Background and Aim: Rheumatoid arthritis is a systemic, chronic and inflammatory disease. It is characterized by the symmetric synovitis  of the articules of the extremities. Its major cause is unknown.Immunological factors including Rheumatoid factor (RF) are considered as more confirming Cause. To date Rheumatoid factor is consisted of many antibodies which are produced against the constant r...

Total IgM, IgA, and IgM-rheumatoid factor (RF) and IgA-RF were quantitated in the serum and synovial fluid of 35 seropositive and 8 seronegative rheumatoid arthritis (RA) patients, using a sensitive enzyme-linked immunosorbent assay (ELISA). Mononuclear cells isolated from peripheral blood and synovial fluid of three seropositive patients were also stimulated in vitro with phorbol myristat...

The idiotypic determinants on IgM rheumatoid factor (RF) from a single family have been analyzed. Rabbit Fab'2 antiidiotypic antibody was prepared against purified IgM-RF from a patient with rheumatoid arthritis. As measured by radioimmunoassay, the antiidiotype reacted with at least 90% of the patient's RF, but not with non-RF immunoglobulins from the same serum, nor with 10 of 11 polyclonal a...

OBJECTIVE To assess the additional diagnostic and clinical value of the second test generation of anti-cyclic citrullinated peptide antibodies (CCP2) compared with rheumatoid factor isotypes (IgG-RF, IgA-RF, IgM-RF) in patients with rheumatoid arthritis. METHODS This was a prospective study on 715 patients: rheumatoid arthritis (n = 295), degenerative or other inflammatory joint disease (n = ...

A 64-year-old woman with rheumatoid arthritis developed Felty's syndrome. Her serum contained large amounts of IgA rheumatoid factor (RF) but insignificant levels of IgM-RF and IgG-RF. It is postulated that the high levels of IgA-RF may have contributed to the neutropenia.
