Inflammatory Phenotypes In Severe Pneumonia: Clinical Evidence To Mouse Models For Precision Therapeutics
Authors' conclusion
By integrating clinical data from human studies and experimental findings in a clinically relevant mouse model, this study provides a translational framework for developing phenotype-targeted therapies for critical illness, with the goal of improving patient outcomes.
Study context
- Population
- ICU patients with pulmonary sepsis; mouse model of pneumococcal pneumonia
- Participants
- 548 ICU patients
- Exposure
- Hyperinflammatory vs hypoinflammatory phenotype
Methodological detailsvalidated classifier models, mouse model of pneumococcal pneumonia
- Validated classifier models
- Mouse model of pneumococcal pneumonia
Main finding
As reported in the abstract
- Two phenotypes in patients: hyperinflammatory with more lung injury and increased mortality; hypoinflammatory with more favorable outcomes
- Latent class analysis (LCA) identified two phenotypes in mice with divergent trajectories (lung injury and mortality) despite uniform pathogen exposure and baseline conditions
- Therapeutic benefit from anti-inflammatory interventions (dexamethasone, IL-6 receptor blockade) exclusively in the more inflamed mice
Observational data: associations, not effects.
