RESUMO
OBJECTIVE:To analyze the effect of daptomycin on methicillin resistant Staphylococcus aureus(MRSA)infection patients with diabetic foot (DF). METHODS:179 patients with type 2 DF complicating with MRSA were randomly divided into daptomycin group (90 cases) and vancomycin group (89 cases),and both groups were included infection group. 80 DF patients without MRSA infection were included in non-infection group. All of them received DF routine treatment ;daptomycin group was additionally given intravenous injection of daptomycin 4 mg/kg,once a day,for 2 weeks;vancomycin group was additionally giv-en intravenous injection of vancomycin 4 mg/kg,once a day,for 2 weeks. RESULTS:After treatment,IL-6,IL-8,MMP-2 and MMP-9 of infection group were significantly decreased,while TIMP-1 levels increased significantly,with statistical significance, compared to before treatment (P<0.05). The effective rate of daptomycin group was 94.4%,which was significantly higher than that of vancomycin group(71.9%),with statistical significance(P<0.05). CONCLUSIONS:Daptomycin can effectively improve the inflammatory status in patients with DF complicated with MRSA infection,to restore the MMPs/TIMPs balance.
