ABSTRACT
ObjectiveTo detect glucose-6-phosphate isomerase (GPI) in knee joint synovial fluid of active rheumatoid arthritis (RA) and explore the correlation between GPI and anti-cyclic citrulline peptide antibody (anti-CCP).MethodsGPI and anti-CCP in the synovial fluid were measured by enzyme linked immunosorbent assay(ELISA) from 22 patients with active RA and 37 patients with active osteoarthritis (OA).Student's t-test was used for intergroup comparison and Spearman's analysis was used for correlation analysis.ResultsThe level of GPI and anti-CCP in the synovial of active RA [ (9.6±8.4) μg/ml,( 14.61 ±18.64) U/ml] was significantly higher than that of active OA[ (0.9±1.8) μg/ml,(1.42±0.09) U/ml)].There was positive correlation between GPI and anti-CCP (r=0.447,P=0.037).ConclusionHigh expression of GPI is shown in active RA synovial fluid.It is suggested that GPI as an antigen that may participate in chronic synovitis,bone destruction and joint malformation.Both GPI and anti-CCP may be the laboratory markers for the diagnosis of RA.
