血培养阴性的高毒力肺炎克雷伯菌多部位感染2例

Two cases of multi-site infections with negative blood cultures caused by hypervirulent Klebsiella pneumoniae

  • 摘要: 高毒力肺炎克雷伯菌(hvkp)多通过血流感染(BSI)而导致多器官或部位感染。本文通过回顾性分析2例山东第一医科大学第二附属医院诊治的非血流感染的多部位hvKP感染者的临床资料,对患者的临床特征、治疗与转归进行归纳分析。本文研究表明,对具有典型高危临床特征(社区发病、多部位脓肿/感染)的患者,即使血培养阴性,仍需积极寻求病灶部位微生物学证据;如有脓肿病灶形成,及时穿刺引流,联合抗菌药物治疗,提高治愈率。

     

    Abstract: Hypervirulent Klebsiella pneumoniae (hvKP) often causes bloodstream infections (BSI), which subsequently lead to multi-organ or multi-site infections. This study retrospectively analyzed the clinical data of two patients with multi-site hvKP infections (non-BSI) diagnosed and treated at the Second Affiliated Hospital of Shandong First Medical University, and their clinical characteristics, treatment and outcomes were summarized. The findings suggest that for patients with typical high-risk clinical features (community-acquired, multi-site abscesses/infections), proactive efforts should be made to obtain microbiological evidence from infection sites even if blood cultures are negative. If abscesses are present, timely puncture and drainage combined with antimicrobial therapy can improve cure rates.
