Leflunomide increases the risk of early healing complications in patients with rheumatoid arthritis undergoing elective orthopedic surgery

Abstract

The aim of this object is to study whether treatment with biological or leflunomide increases the risk of wound-healing complications after elective orthopedic surgery. Between March 2002 and September 2003, 201 patients participated in this study with the following inclusion criteria: (a) Rheumatoid arthritis (RA) or psoriatic arthritis (psA), (b) therapy with: MTX, leflunomide, etanercept, infliximab, adalimumab, anakinra, (c) undergoing elective orthopedic surgery. The incidence of early postoperative wound-healing complications was compared among the different groups. In comparison with patients who received MTX therapy (n = 59), the risk of postoperative wound-healing complications in patients undergoing leflunomide therapy (n = 32) was significantly higher: 13.6% in the MTX group, 40.6% in the leflunomide group (P = 0.01). It is recommended that leflunomide medication for patients with RA undergoing elective orthopedic surgical procedure is interrupted preoperatively to reduce the risk of early wound-healing complications or infections.
