Microbial and Clinical Disparities in Pneumonia: Insights from Metagenomic Next-Generation Sequencing in Patients with Community-Acquired and Severe Pneumonia (PRJCA039020)

This study aims to investigate the clinical, microbiological, and microbiome differences between patients with community-acquired pneumonia (CAP) and severe pneumonia (SP) through advanced metagenomic next-generation sequencing (mNGS) technology. By analyzing bronchoalveolar lavage fluid (BALF) samples from 204 CAP and 25 SP patients, The substantial differences observed in clinical characteristics, pathogen profiles, and microbiomes between patients with community-acquired pneumonia (CAP) and those with severe pneumonia (SP) highlight the imperative need for comprehensive diagnostic methodologies in the management of pneumonia. Metagenomic next-generation sequencing (mNGS) has demonstrated substantial utility in informing personalized treatment strategies, with the potential to enhance clinical outcomes. Future research should prioritize elucidating the dynamics of microbial communities and their impact on pneumonia severity, with the objective of refining and optimizing therapeutic strategies.
