【 摘 要 】
Rheumatoid arthritis (RA) is the most common chronic inflammatory joint disorder and anti-cyclic citrullinated peptide antibody (anti-CCP Ab) is regarded as a serological marker for diagnosing early and late RA. In the present study, we aimed to determine the levels of anti-CCP Ab in serum, synovial tissue (ST) and synovial fluid (SF) in RA patients undergoing total knee arthroplasty (TKA). 23 patients were included. Rheumatoid factor (RF) and anti-CCP Ab in serum were detected prior to surgery and then at 1, 3, 6 and 12 months after TKA. Synovial samples were obtained by knee arthroscopy and used for anti-CCP detection. One month after TKA, anti-CCP levels were significantly reduced (P < 0.01) in RA patients. However, their levels were not significantly different between pre-surgery and 1 year post-surgery (P > 0.05). Furthermore, anti-CCP levels in ST were much higher than in serum. These findings suggest that RA patients should continue antirheumatic therapy after TKA. ST is the preferred place for the synthesis of anti-CCP Ab.
