BAL Fluid Cellularity Reflects Fungal Burden, Not Mortality, in Pulmonary Aspergillosis
An observational study of 63 patients with hematologic malignancy and culture-documented invasive pulmonary aspergillosis found that bronchoalveolar lavage fluid cellularity reflected peripheral cytopenias, fungal burden, and respiratory coinfections. Cellularity was not independently associated with 42-day mortality.
- Study included 63 patients with hematologic malignancy and pulmonary aspergillosis.
- BALF cellularity reflected peripheral cytopenias, fungal burden, and respiratory coinfections.
- Cellularity was not independently associated with 42-day mortality.
- Persistent neutropenia and critical illness were reported mortality drivers.
Investigators characterized bronchoalveolar lavage fluid (BALF) leukocyte profiles in 63 patients with hematologic malignancy and culture-documented invasive pulmonary aspergillosis. The observational study evaluated associations between BALF cellularity and peripheral blood leukocyte counts, Aspergillus burden, respiratory coinfections, and clinical outcomes, including 42-day mortality.
BALF cellularity mirrored peripheral cytopenias but increased with higher Aspergillus burden and respiratory coinfections. These findings suggest that lavage leukocyte profiles reflect both systemic immune cell availability and local inflammatory stimuli. However, BALF cellularity was not independently associated with 42-day mortality; persistent neutropenia and critical illness were the reported drivers of mortality.
The findings suggest limited independent prognostic value for BALF cellularity in this population. Interpretation is constrained by the small sample and restriction to patients with hematologic malignancy and culture-documented infection. Only the abstract was available; mortality rates, effect estimates, and details of adjustment were not provided.
