Study Summary
Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous disease that affects only a fraction of those who smoke tobacco. The origin of this variability in susceptibility to develop COPD is unclear, but understanding its underlying biology has important implications for our ability to design suitable preventative and therapeutic strategies for its management. This Department of Defense (DOD) discovery research proposes to develop methodologies and generate preliminary data needed to lay the foundation for a large study that would investigate the underlying biological susceptibility of those who smoke tobacco to develop COPD.
Primary Outcome
Number of macrophages measured by flow cytometry.
Interventions
- PROCEDURE Bronchoscopy with Bronchoalveolar Lavage (BAL)
