METHODS: This paper reports a rare case of sepsis caused by combined infection with Legionella pneumophila and Fusobacterium necrophorum, leading to respiratory failure, acute kidney injury, acute liver injury, myocardial damage, and electrolyte disorders. In addition, we systematically reviewed literature on patients with combined Legionella infections, analyzing their clinical features, laboratory results and diagnosis.
CONCLUSIONS: For pathogens that require prolonged incubation periods and are less sensitive to conventional culturing methods, metagenomic next-generation sequencing (mNGS) can be a powerful supplement to pathogen screening and plays a significant role in the auxiliary diagnosis of complex infectious diseases.
方法:本文报道一例罕见的由嗜肺军团菌和坏死梭菌联合感染引起的脓毒症,导致呼吸衰竭,急性肾损伤,急性肝损伤,心肌损伤,和电解质紊乱。此外,我们系统回顾了军团菌联合感染患者的文献,分析他们的临床特征,实验室结果和诊断。
结论:对于需要延长潜伏期且对常规培养方法不太敏感的病原体,宏基因组下一代测序(mNGS)可以作为病原体筛查的有力补充,在复杂传染病的辅助诊断中起着重要作用。
