Abstract

Objectives: The translocation of intestinal flora has been linked to the colonization of diverse and heavy lower respiratory flora in patients with septic ARDS, and is considered a critical prognostic factor for patients.

Methods: On the first and third days of ICU admission, BALF, throat swab, and anal swab were collected, resulting in a total of 288 samples. These samples were analyzed using 16S rRNA analysis and the traceability analysis of new generation technology.

Results: On the first day, among the top five microbiota species in abundance, four species were found to be identical in BALF and throat samples. Similarly, on the third day, three microbiota species were found to be identical in abundance in both BALF and throat samples. On the first day, 85.16% of microorganisms originated from the throat, 5.79% from the intestines, and 9.05% were unknown. On the third day, 83.52% of microorganisms came from the throat, 4.67% from the intestines, and 11.81% were unknown. Additionally, when regrouping the 46 patients, the results revealed a significant predominance of throat microorganisms in BALF on both the first and third day. Furthermore, as the disease progressed, the proportion of intestinal flora in BALF increased in patients with enterogenic ARDS.

Conclusions: In patients with septic ARDS, the main source of lung microbiota is primarily from the throat. Furthermore, the dynamic trend of the microbiota on the first and third day is essentially consistent.It is important to note that the origin of the intestinal flora does not exclude the possibility of its origin from the throat.

咽喉微生物群驱动脓毒症 ARDS 患者肺泡微生物群的改变。
目的肠道菌群的转移与脓毒症 ARDS 患者下呼吸道菌群的多样性和重度定植有关,被认为是影响患者预后的关键因素:方法: 在入住重症监护室的第一天和第三天,采集肺泡液、咽拭子和肛拭子,共计 288 份样本。采用 16S rRNA 分析和新一代溯源分析技术对这些样本进行分析:结果:第一天,在丰度排名前五位的微生物群种类中,有四个种类在肺泡和咽喉样本中是相同的。同样,在第三天,BALF 和咽喉样本中发现三个微生物群种类的丰度相同。第一天,85.16%的微生物来自咽喉,5.79%来自肠道,9.05%未知。第三天,83.52%的微生物来自喉咙,4.67%来自肠道,11.81%未知。此外,将 46 名患者重新分组后,结果显示,在第一天和第三天,BALF 中的咽喉微生物明显占优势。此外,随着病情的发展,肠源性ARDS患者BALF中的肠道菌群比例增加:脓毒症 ARDS 患者肺部微生物群的主要来源是咽喉。值得注意的是,肠道菌群的来源并不排除其来自咽喉的可能性。

期刊介绍: Virulence is a fully open access peer-reviewed journal. All articles will (if accepted) be available for anyone to read anywhere, at any time immediately on publication. Virulence is the first international peer-reviewed journal of its kind to focus exclusively on microbial pathogenicity, the infection process and host-pathogen interactions. To address the new infectious challenges, emerging infectious agents and antimicrobial resistance, there is a clear need for interdisciplinary research.
