Serum YKL-40 levels and disease characteristics in patients with rheumatoid arthritis
Background: The present study aimed to evaluate serum YKL-40 levels in patients with rheumatoid arthritis (RA) compared to healthy subjects and to search whether there is an association between YKL-40 levels and disease characteristics in RA. Methods: In this cross-sectional study, 60 RA patients based on the ACR/EULAR 2010 criteria and 30 age- and sex-matched healthy controls were included. I...
متن کاملCorrelation between anti-nuclear antibodies (ANA), rheumatoid factor (RF), anti-cyclic citrullinated peptides antibodies (Anti-CCP) and percentage and type of pulmonary involvement in patients with rheumatoid arthritis, Booali Hospital Tehran (2016-2
Background: Controlling the pulmonary involvement, as one of the most common extra-articular consequences in rheumatoid arthritis (RA), can improve the life quality and survival rate of patients. This study aimed to evaluate the correlation between disease-related inflammatory factors and the severity and type of lung involvement in patients, which is a practical step toward early detection and...
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 کاملAntinuclear factors in rheumatoid arthritis. Increasing organ-non-specificity with increasing reactivity of rheumatoid factor with heterologous gamma globulin.
McCormick and Day (1963) reported that rheumatoid factors and 7S ANF co-existing in the same seramayform high molecular weight complexes, and absorption studies have brought forward evidence of an interaction between ANF and rheumatoid factors when present in the same serum (Holborow and Johnson, 1965). However, ANF in rheumatoid arthritis have mostly been found in low frequency and chiefly in ...
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...
