Brief Summary:
The primary objective of this study is to show that the Supraglottic Index (SGI) is an easily-collected index that accurately identifies the presence and severity of laryngopharyngeal reflux (LPF) in idiopathic pulmonary fibrosis (IPF).

Condition or disease
IPF Reflux

Detailed Description:
The study team hypothesizes the SGI will correlate more strongly with measures of IPF severity (at baseline and over time) than gastroesophageal reflux (GER) data derived from the esophageal detector channels of a pH/impedance probe.

Outcome Measures

Primary Outcome Measures :
  1. The supraglottic index (SGI) quantifies laryngopharyngeal reflux (LPF) and is associated with severity of pulmonary fibrosis. [ Time Frame: 6 months ]
    Correlation between the supraglottic index and forced vital capacity. The supraglottic index is an index derived by assigning scores for edema and erythema of five supraglottic structures (epiglottis, false cords, arytenoids, posterior commissure, piriform recess) as viewed through a fiber-optic scope. Scores range from 0-22, with higher scores indicating more severe LPR.
