Circulating microRNAs can identify endotypes of community-acquired pneumonia

Background: The identification of the host processes dysregulated in community-acquired pneumonia (CAP) patients, especially in those who develop severe complications could be crucial for future management of this disease. We aim to study microRNAs profiles to define different CAP endotypes regarding complications. Methods: An observational prospective study of consecutive hospitalized CAP cases was performed. Circulating microRNAs were analyzed using qRT-PCR. We study correlations and predictive value of miRNAs regarding severe sepsis and acute hypoxemic respiratory failure (AHRF: PaO2/FiO2 Results: We analyzed clinical data and blood samples from 169 CAP patients. The mean age was 66.9 ye…
