Abstract
Purpose of review: This review focus on the clinical value of salivary and laryngopharyngeal tissue pepsin measurement in the diagnosis and treatment of laryngopharyngeal reflux (LPR).
Recent findings: A growing body of research suggests that salivary pepsin detection provides a noninvasive method for the identifying LPR occurrence. Pepsin detection testing is still variable, and an optimal method that balances utility with accuracy has not been agreed. Timing and number of test samples recommended also remains controversial, however literature indicates that increasing the number of tests over a day increases pepsin detection rate. It remains unclear whether detection of pepsin alone can be used to confirm LPR diagnosis. Pepsin positivity is correlated with improved response to proton pump inhibitor (PPI) therapy, and therefore may play a role in guiding therapeutic choices. Detection of pepsin in laryngeal tissue has the same clinical value as detection in saliva and requires further investigation to determine utility.
Summary: As a noninvasive method for the diagnosis of LPR, the detection of salivary pepsin in the oropharynx shows potential clinical value, however the exact method of detection and diagnostic values are unclear. Salivary or tissue-based pepsin detection may be helpful in predicting therapeutic effects of PPI and providing personalized treatment options. The detection threshold of salivary pepsin may be different in different countries and regions. Timing and number of samples needed for detection is still controversial.
