BACKGROUND
The primary aim of this study was to describe the frequency of pulmonary infiltrates on chest X-ray (CXR) during community acquired Gram-negative bacteremia at a single centre in Denmark.
METHODS
The patients were retrospectively identified from the laboratory information system and clinical and radiological data were retrieved from the electronic health records. Overall 114 patients with E.coli or K.pneumoniae bacteremia fulfilled the inclusion criteria during the period 2009-2010.
RESULTS
CXR was performed in 77% of cases (80% of E.coli and 56% of K.pneumoniae) among which infiltrates were identified in 34%. The two most frequent localizations of infiltrates during E.coli bacteremia were lower lobe/basal (56%) and diffuse (22%). Furthermore, 30% of infiltrates were bilateral while 40% were present on the right lung and 30% on the left lung.
CONCLUSIONS
In conclusion, the presence of infiltrates during community acquired Gram-negative bacteremia was very frequent in our population.
背景
本研究的主要目的是描述在丹麦的一个单一中心，社区获得性革兰氏阴性菌血症患者的胸部 X 线（CXR）上肺部浸润的频率。
方法
从实验室信息系统中回顾性地确定患者，从电子健康记录中检索临床和放射学数据。在 2009-2010 年期间，符合纳入标准的大肠杆菌或肺炎克雷伯菌血症患者共有 114 例。
结果
在 77%的病例中进行了 CXR（大肠杆菌为 80%，肺炎克雷伯菌为 56%），其中 34%发现有浸润。大肠杆菌菌血症中浸润最常见的两个部位是下叶/基底部（56%）和弥漫性（22%）。此外，30%的浸润是双侧的，40%位于右肺，30%位于左肺。
结论
总之，我们的人群中社区获得性革兰氏阴性菌血症患者存在浸润的情况非常普遍。
