Using metagenomic next-generation sequencing (mNGS), the bronchoalveolar lavage fluid (BALF) of the two groups was analyzed, and the microbial results and clinical data were compared.Results: Compared with the control group, the infants in the PCP group had a lower incidence of cough (25% vs 78.8%; P < 0.05), a greater history of surgery (50.0% vs 39.1%; P < 0.05), and a more significant decrease in C3, C4, and CD4/CD8 ratios (all P < 0.05). The pathogenic bacteria in the BALF included P. jirovecii, respiratory syncytial virus, cytomegalovirus (CMV), and Staphylococcus aureus. The predominance of viral infection in the PCP group was significantly higher than in the control group (P < 0.05), especially CMV (43.5% vs 15.2%; P < 0.05). The top five symbiotic microorganisms detected in the BALF of the 49 infants were Streptococcus, Propionibacterium, Rothia, Staphylococcus, and Moraxella. There was no significant difference in the relative abundance of common symbiotic microorganisms between the two groups (all P > 0.05).Conclusion: Non-HIV PCP has a higher incidence in PICU infants with severe pneumonia, especially those with underlying diseases or who are immunocompromised, which are clinically difficult to treat. A BALF analysis using mNGS is helpful for early and clear diagnoses. It also helps to clarify the distribution of pathogenic and lower respiratory tract colonizing bacteria in infants with severe pneumonia.Keywords: non-HIV Pneumocystis jirovecii pneumonia, metagenomic next-generation sequencing, pathogen detection, lower respiratory tract microorganisms, severe pneumonia, infants |
