The aim of this study is to describe clinical characteristics and outcome of Burkholderia cepacia bacteraemia, susceptibility of the isolates and differences between cases from epidemic outbreaks and sporadic cases.
From 1993 to 2009, episodes of B. cepacia bacteraemia were prospectively collected in a university hospital.
A total of 33 episodes were included, of which 21 were part of two outbreaks (9 in 1994 and 12 in 2006). Outbreak cases had a median age of 58 years, 45% had neoplasia, median length of stay until bacteraemia was 15 d (range 0-120) and 82% had received an antibiotic. The most prevalent sources of bacteraemia were catheter (48%) and unknown (33%). On the other hand, sporadic cases stayed longer until diagnosis (median 25 days versus 11, p=0.041) and showed a trend to have neoplasia more frequently (83% versus 33%, p=0.083). Susceptibility to antibiotics was varied and co-trimoxazole was the only active agent against all strains.
B. cepacia is an uncommon pathogen, which affects patients with prolonged hospitalization and severe comorbidities. The identification of more than one case in a short term of time should raise the suspicion of an outbreak.
本研究旨在描述洋葱伯克霍尔德菌血症的临床特征及转归、分离菌株的药敏情况,以及疫情暴发病例与散发病例之间的差异。
1993年至2009年,前瞻性收集某大学医院的洋葱伯克霍尔德菌血症病例。
共纳入33例病例,其中21例是两次疫情暴发的一部分(1994年9例,2006年12例)。疫情暴发病例的中位年龄为58岁,45%患有肿瘤,菌血症发生前的中位住院时间为15天(范围0 - 120天),82%接受过抗生素治疗。菌血症最常见的来源是导管(48%)和不明来源(33%)。另一方面,散发病例直到诊断的时间更长(中位25天对11天,p = 0.041),且肿瘤发生率有更高的趋势(83%对33%,p = 0.083)。抗生素敏感性各不相同,复方新诺明是唯一对所有菌株有效的药物。
洋葱伯克霍尔德菌是一种不常见的病原体,影响长期住院且伴有严重合并症的患者。短期内发现不止一例病例应引起对疫情暴发的怀疑。
