Survivin belongs to the family of inhibitor of apoptosis proteins and plays an important role in the hyperplastic growth of tissues and tumors. In this study, we assessed the expression of survivin in rheumatoid synovial fluids (SF) and synovial tissues (ST) of rheumatoid arthritis (RA) patients in order to investigate the role of extracellular survivin in the pathogenesis of RA. The survivin level from SF was significantly higher in RA patients (n = 38) than in osteoarthritis patients (n = 18; 10.68 ± 2.76 vs. 1.0 ± 0.56 pg/ml, p = 0.02). In addition, SF survivin level was higher in erosive RA patients (n = 23) than in non-erosive RA patients (n = 15; 15.26 ± 4.26 vs. 4.47 ± 1.12 pg/ml, p = 0.05). SF survivin level in RA was positively correlated with disease activity score 28, but did not reach statistical significance (r = 0.309, p = 0.07). RA SF survivin level was also positively correlated with peripheral blood leukocyte counts (r = 0.443, p = 0.005). The immunohistochemical staining and Western blot analysis revealed survivin expression in the ST and fibroblast-like synoviocytes of RA patients, respectively. These findings suggest that extracellular survivin may be produced from rheumatoid FLS and may play an important role in the destructive RA process.
