摘　　要：目的观察达托霉素对万古霉素疗效欠佳的左心感染性心内膜炎(LIE)临床治疗效果。方法回顾性分析6例LIE诊治经过,并行文献复习。结果前5例LIE均合并瓣周脓肿,经规范万古霉素抗感染治疗,病情仍继续进展,其中4例急症行瓣膜置换术,但术后仍发热,换用达托霉素6 mg/kg,每日1次,治疗2~4周,获得满意疗效。第5例患者术前换用达托霉素治疗后,感染一度控制,但后来病情仍继续进展,再行手术治疗成功,但于术后21 d猝死。第6例为自体瓣膜心内膜炎,外院先后应用哌拉西林-他唑巴坦2周,万古霉素3周,仍发热,赘生物增加,换用达托霉素后体温下降,赘生物减少。6例患者用药后1例肌酸激酶轻度升高,5例正常,无明显不良反应。随访除1例心源性猝死,其余患者随诊18个月至5年生存质量良好。结论初步观察达托霉素用于万古霉素治疗疗效欠佳的心内膜炎少数病例的补救治疗可取得较好疗效。Objective To evaluate the efficacy of daptomycin in the treatment of left-sided infective endocarditis after failing to respond to vancomycin. Methods A retrospective analysis was conducted for 6 cases of infective endocarditis. Results Five of the six infective endocarditis patients were complicated with paravalvular abscess（artificial valve in 3 cases, native valve in 2 cases）. Their disease deteriorated even under vancomycin treatment. Four of these patients received emergency valve replacement surgery but still febrile after operation. The antimicrobial therapy was switched to daptomycin at dose of 6 mg/kg daily for 2 to 4 weeks. The patients responded satisfactorily to daptomycin. The infection was controlled to some extent in the fifth patient after switching to daptomycin, but recurred later, and died suddenly on day 21 after reoperation. The sixth patient had infective endocarditis of native valve, and had treated with piperacillin-tazobactam for 2 weeks and vancomycin for 3 weeks, but responded poorly. The patient still had fever and enlarged vegetation. Switching to daptomycin reduced the body temperature and vegetation. Serum creatine kinase elevated moderately in one patient, and normal in the other 5 patients. No other apparent adverse reaction was reported. One patient died and the other five patient survived well for 18 months to 5 years. Conclusions Preliminary observation demonstrates the efficacy of daptomycin salvage treatment in a few cases of left-sided infective endocarditis after failing to respond to vancomycin therapy.
