Brief Summary

Hypothesis 1: Microaspiration, as diagnosed by bronchoalveolar lavage (BAL) pepsin, is common in patients with IPF.

Hypothesis 2a: Baseline clinical variables and co-morbid conditions are risk factors for microaspiration in patients with IPF.

Hypothesis 2b: Baseline biological variables reflecting alveolar epithelial injury and inflammation are markers of microaspiration in IPF.

Hypothesis 3a: Microaspiration will lead to a more rapid rate of decline in pulmonary function.

Hypothesis 3b: Microaspiration will lead to higher rates of urgent medical care use (i.e. unscheduled clinic visit, emergency room visit, or hospitalization).

This is a prospective cohort study of patients with IPF. Subjects will undergo (1) an assessment of the presence or absence of microaspiration (via bronchoscopy and BAL pepsin level), (2) measurement of biomarkers of microaspiration (via esophageal function studies, laboratory tests, pulmonary function, chest imaging, and survey), and (3) longitudinal follow-up to document disease progression (via pulmonary function and survey).
