Neutrophil CD64 index for rapid diagnosis of Pneumocystis jirovecii pneumonia in malignancy patients requiring mechanical ventilation: a retrospective analysis

Key Points

• The neutrophil cd64 index provides quick diagnostic insights for pneumonia in patients under mechanical ventilation.
• An increase in the nCD64 index is associated with a heightened risk of mortality, highlighting its prognostic value.
• Observational analysis indicates that dynamic tracking of the nCD64 index can inform treatment strategies effectively.
• This approach suggests potential improvements in patient management, though further validation in larger cohorts is warranted.
