Objective To evaluate the inflammatory markers in patients with ankylosing spondylitis (AS) or non-inflammatory diseases undergoing total hip arthroplasty (THA) and to ascertain the variation trend of perioperative inflammatory markers and the influence of inflammation markers after THA. Methods Between January 2013 and December 2014, 153 consecutive patients with AS were included. According to the range of motion (ROM), the patients were divided into ankylosis group (ROM: 0°; group A, n=92) and stiff group (ROM: 3-46°; group B, n=61); 120 noninflammatory diseases patients having no bacterial infection and undergoing primary THA served as non-inflammatory group (group C). The inflammatory markers including C-reactive protein (CRP), interleukin-6 (IL-6), and erythrocyte sedimentation rate (ESR) concentrations were measured before operation and at 1, 3, 5, and 7 days after operation, and the complication was observed. Results Perioperative serum CRP, IL-6, and ESR increased at first after operation, and then decreased in 3 groups. There were significant differences in CRP and ESR between at pre- and post-operation (P<0.05); the IL-6 at 1, 3, and 5 days after operation were significantly higher than that at preoperation (P<0.05), but no significant difference was found between at 7 days and at preoperation (P>0.05). CRP, IL-6, and ESR of group B were significantly higher than those of group A at preoperation (P<0.05); CRP and IL-6 of groups A and B were significantly higher than those of group C at preoperation and at 1 day after operation (P<0.05); ESR of groups A and B was significantly higher than that of group C at preoperation, and at 1 day and 3 days after operation (P<0.05); and no significant difference was shown among 3 groups at the other time points (P>0.05). No inflammatory activity or increased complication was observed. Conclusion AS and non-inflammatory diseases show similar change trend of inflammatory markers at preand post-operation. The inflammatory activity of AS has no significant effect on the changes of inflammation markers and does not increase the incidence of postoperative complications.
