What this trial studies
This observational study aims to evaluate the Supraglottic Index (SGI) as a reliable measure for identifying the presence and severity of laryngopharyngeal reflux (LPF) in patients with idiopathic pulmonary fibrosis (IPF). The researchers hypothesize that the SGI will show a stronger correlation with IPF severity compared to traditional gastroesophageal reflux (GER) data obtained from pH/impedance probes. Participants will be monitored over time to assess the relationship between SGI and IPF progression.
Why it matters
Potential benefit: If successful, this study could provide a new, easily collected index for assessing reflux in IPF patients, potentially leading to better management of their condition.
How similar studies have gone: While the approach of using SGI in this context is novel, similar studies have shown the importance of reflux assessment in respiratory conditions.
