Clinical factors related to the efficacy and complications of orthopedic surgery for rheumatoid arthritis with infliximab.
International Journal of Rheumatic Diseases 2011 Februrary
AIMS: To determine what clinical factors relating to efficacy besides complications of orthopedic surgery for patients treated with anti-tumor necrosis factor (TNF)-α therapy (infliximab), we analyzed the clinical data of 52 cases of orthopedic surgery, such as total hip arthroplasy (THA), total knee arthroplasty (TKA), total shoulder arthroplasy (TSA), total elbow arthroplasty (TEA), arthroscopic synovectomy, foot arthroplasty, spine surgery, hand surgery and fracture.
METHODS: We analyzed clinical factors including age, disease duration, preoperative C-reactive protein (CRP), disease activity score (DAS)-28, matrix metalloproteinase (MMP)-3, and rheumatoid arthritis particle-agglutination (RAPA) in 52 cases of rheumatoid arthritis (RA) undergoing orthopedic surgery. For complications of orthopedic surgery, signs of postoperative infection were recorded, including rubor, discharge, systemic infection and frequencies of wound dehiscence, as well as the incidence of any surgical complication requiring a secondary revision procedure were measured.
RESULTS: Signs of infection or surgical complications occurred in two of 52 patients (3.8%). There is significant correlation between RAPA and improvement of CRP 3 months after surgery; however, there is no correlation between infection and clinical factors including age, disease duration, preoperative CRP, MMP-3, RAPA and the period until surgery after infliximab infusion.
CONCLUSION: Infliximab did not increase the risk of either infections or surgical complications occurring in patients with RA within 1 year of orthopedic surgery. Improvement of CRP after surgery is likely to be due to infliximab for high RAPA in RA patients.
