Abstract: | Objective To evaluate perioperative changes in rheumatoid arthritis (RA) patients treated with tocilizumab. Methods We collected RA cases with tocilizumab and orthopaedic surgery from 1999 to 2010. Incidences of postoperative infections, delayed wound healing, and RA symptom flare-ups were extracted from the data for comparison with patients without these postoperative events. We also evaluated the changes in C-reactive protein (CRP) and body temperature in patients without postoperative complications with normal CRP before surgery, i.e., patients without postoperative events in whom the tocilizumab level was maintained, for each duration to discontinuation before surgery. Results A total of 161 cases (n = 122) were collected. The patients had mean age of 56.9 years, and mean disease duration of 12.8 years at operation. Joint replacement surgery was performed in 89 cases. Three patients had postoperative infections (two superficial and one organ/space surgical-site infection), 20 had delayed wound healing, and 36 had RA symptom flare-ups. Delayed wound healing occurred most commonly in patients who underwent spinal surgery (P = 0.0061, versus patients without delayed wound healing). CRP levels were high when tocilizumab was restarted in patients with RA symptom flare-ups (P = 0.0010, versus patients without RA symptom flare-ups). Increased postoperative CRP was observed in patients without postoperative events when the duration from final tocilizumab infusion to surgery was long. The changes in body temperature showed a similar trend to CRP. Conclusions Although it has been demonstrated that infection rates in patients treated with tocilizumab are by no means high, incidence of delayed wound healing was significantly higher in cases with surgical interventions such as foot and spinal surgeries. Many patients treated with tocilizumab remained in a normal range of CRP even during the perioperative period. For prevention of perioperative complications, observation of postoperative conditions and surgical wounds, and subjective symptoms of patients are considered important. |
