We describe 3 patients with left-sided staphylococcal endocarditis (1 with methicillin-susceptible Staphylococcus aureus [MSSA] prosthetic aortic valve endocarditis and 2 with methicillin-resistant S. aureus [MRSA] native-valve endocarditis) who were successfully treated with high-dose intravenous daptomycin (10 mg/kg/day) plus fosfomycin (2 g every 6 h) for 6 weeks. This combination was tested in vitro against 7 MSSA, 5 MRSA, and 2 intermediately glycopeptide-resistant S. aureus isolates and proved to be synergistic against 11 (79%) strains and bactericidal against 8 (57%) strains. This combination deserves further clinical study.
我们描述了 3 例左侧葡萄球菌性心内膜炎患者(1 例为耐甲氧西林金黄色葡萄球菌 [MSSA] 人工主动脉瓣心内膜炎,2 例为耐甲氧西林金黄色葡萄球菌 [MRSA] 原生瓣膜心内膜炎),他们均成功接受了 6 周高剂量静脉滴注达托霉素(10mg/kg/天)加磷霉素(每 6 小时 2g)治疗。该联合用药在体外对 7 株 MSSA、5 株 MRSA 和 2 株中度糖肽耐药金黄色葡萄球菌分离株进行了测试,结果显示对 11 株(79%)菌株具有协同作用,对 8 株(57%)菌株具有杀菌作用。这种联合用药值得进一步的临床研究。
