Pseudomonas aeruginosa is one leading gram-negative organism associated with nosocomial infections. Bacteremia is life-threatening in the immunocompromised host. Increasing frequency of multi-drug-resistant (MDRPA) strains is concerning. We started a retrospective survey in the pediatric hematology oncology Italian network. Between 2000 and 2008, 127 patients with Pseudomonas aeruginosa bacteremia were reported from 12 centers; 31.4% of isolates were MDRPA. Death within 30 days of a positive blood culture occurred in 19.6% (25/127) of total patients; in patients with MDRPA infection it occurred in 35.8% (14/39). In the multivariate analysis, only MDRPA had significant association with infection-related death. This is the largest series of Pseudomonas aeruginosa bacteremia cases from pediatric hematology oncology centers. Monitoring local bacterial isolates epidemiology is mandatory and will allow empiric antibiotic therapy to be tailored to reduce fatalities.
铜绿假单胞菌是一种与医院感染相关的主要革兰氏阴性菌。菌血症在免疫功能低下的宿主中是危及生命的。日益增多的多药耐药(MDRPA)菌株令人担忧。我们在意大利儿科血液肿瘤网络中开展了一项回顾性调查。2000 年至 2008 年间,12 个中心报告了 127 例铜绿假单胞菌菌血症患者;其中 31.4%的分离株为 MDRPA。总患者中,30 天内阳性血培养相关死亡的发生率为 19.6%(25/127);在 MDRPA 感染者中,死亡率为 35.8%(14/39)。多变量分析显示,只有 MDRPA 与感染相关死亡有显著相关性。这是来自儿科血液肿瘤中心的最大系列铜绿假单胞菌菌血症病例。监测当地细菌分离株的流行病学是强制性的,这将有助于调整经验性抗生素治疗,以降低死亡率。
