Abstract
Purpose: Our aim was to investigate the clinical efficacy and complications of antibiotics treatment duration for the patients of bone infection. Methods: We retrospectively analyzed the patients with bone infection admitted to our hospital between March 2013 and October 2018. The surgical debridement was performed and the patients were divided into three groups: IV group (Intravenous antibiotics for 2 weeks); Oral group (Intravenous antibiotics for 2 weeks followed by oral antibiotics for 4 weeks); Rifampicin group (Intravenous antibiotics for 2 weeks followed by oral antibiotics plus rifampicin for 4 weeks). The infection control rate and complications were compared. Results : A total of 902 patients were enrolled, the infection sites included 509 tibias, 228 femurs, 32 humeri, 23 radii and ulnae, 40 calcanei, 23 multiple-site infections and the other sites 47 cases. After at least 6 months of follow-up, 148 (16.4%) patients had recurrence of infection. The recurrence rate of IV group was 17.9%, which was no significant higher than that of Oral group (10.1%) or Rifampicin group (10.5%). The abnormal rate of Glutamic-pyruvic transaminase(ALT) in IV group was 15.1%, which was lower than that of Oral group (18.0%) and Rifampicin group (27.4%), P=0.026. The positive rates of proteinuria in the three groups were 3.2%, 4.5%, and 9.3%, respectively, P=0.020. Conclusion: After debridement of bone infection, the additional oral antibiotic treatment may increase the damage of liver and kidney, and can not significantly reduce the infection recurrence rate. Therefore, it is recommended to adopt short-term systemic antibiotic treatment after debridement.
