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...
Background: There are several evidences that genetic factors besides environmental triggers have important role in initiating the rheumatoid arthritis (RA). The aim of this study was to investigate the association of rheumatoid arthritis with different subtypes of HLA DR4 in Iranian patients. Methods: In an un-matched case control study, 110 rheumatoid arthritis patients (case) and 56 knee ost...

The aim of this study was to investigate the effect of bromocriptine on clinical and laboratory findings of rheumatoid arthritis. Materials and methods: Ïn this randomized double-blind placebo-controlled cross-over clinical trial, 10 patients wit...
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 myristate ace...
