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.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 40-95 diagnosed with idiopathic pulmonary fibrosis who can communicate in English.

Not a fit: Patients who do not meet the inclusion criteria or are pregnant will not benefit from this study.

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 performed: While the approach of using SGI in this context is novel, similar studies have shown the importance of reflux assessment in respiratory conditions.
