Laryngopharyngeal reflux diagnosis in obstructive sleep apnea patients using the pepsin salivary test
Background: To investigate the presence of laryngopharyngeal reflux in
patients with obstructive sleep apnea (OSA) employing the salivary pepsin
concentration method. To compare the results of pepsin concentration with the
severity of the pathology. Methods: Seventy-five OSA patients (44 males, 31
females) were enrolled in the study. For each patient, the AHI (apnea–hypopnea
index) and the BMI (body mass index) were initially evaluated. All the patients
enrolled were assessed using the reflux symptom index (RSI) and the reflux finding
