Coughing our guts up: how do we diagnose reflux cough?

Area of Science:

• Gastroenterology
• Pulmonology

Background:

• Chronic cough is a common and often challenging condition to diagnose.
• Reflux is a potential contributing factor to chronic cough, necessitating accurate diagnostic tools.

Discussion:

• The Peptest, a non-invasive biomarker for detecting refluxate in the upper airway, shows promise for cough clinics.
• Routine use of Peptest can be valuable but requires integration into a comprehensive diagnostic workup.
• Identifying the specific nature and characteristics of the reflux is crucial for effective management.

Key Insights:

• Peptest can effectively identify the presence of reflux in patients with chronic cough.
• The diagnostic utility of Peptest is maximized when combined with detailed clinical assessment and potentially other investigations.
• A multi-faceted approach is essential for accurately diagnosing and managing reflux-induced cough.

Outlook:

• Further research should explore the optimal integration of Peptest into various clinical pathways for chronic cough.
• Standardizing the interpretation and application of Peptest results will enhance its clinical utility.
• This approach may lead to improved patient outcomes by enabling more targeted and effective treatments for chronic cough.
