Affect of rhTNFR:Fc on postoperative recovery of patients with inflammatory arthritis / 中华风湿病学杂志

ABSTRACT

Objective To investigate the affect of rhTNFR:Fc on the postoperative recovery of patients with inflammatory arthritis after arthroplasty. Methods Patients with inflammatory arthritis undergoing arthroplasty were included and divided into rhTNFR:Fc group (rhTNFR:Fc only or combined with conven-tional DMARDs) and conventional DMARDs group (monotherapy with or combination of conventional DMARDs). We retrospectively analyzed the incidence of postoperative infection, wound healing time, the febrile period (body temperature ≥37.5 ℃) and the duration of antibiotics treatment after arthroplasty. x2 test and t test were used for statistical analysis. Results Sixty-seven patients were included, 18 in the rhTNFR: Fc group and 49 in the conventional DMARDs group. One postoperative infection occurred in rhTNFR :Fc group but none in the DMARDs group. There was no significant difference by Fisher's exact test (P＞0.05). The febrile duration was (4±3) days in the rhTNFR :Fc group and (3±3) days in the conventional DMARDs group, the difference was not statistically significant (P＞0.05). The wound healing time was (14.0±3.1) days in the rhTNFR :Fc group and (14.7±2.9) days in the conventional DMARDs group, which was not statistically different(P＞0.05). The duration of antibiotics treatment after operation was (14.8±9.3) days in the rhTNFR: Fc group and (10.3±2.7) days in the conventional DMARDs group, the difference was statistically significant (P＜0.05). Conclusion Using rhTNFR:Fc during perioperative period in patients with inflammatory arthritis does not increase the risk of infectious complications or extending wound healing time and the febrile duration.
