The Impact of Laryngopharyngeal Reflux on Occurrence and Clinical Course of Recurrent Respiratory Papillomatosis

xlomafota13 shared this article with you from Inoreader The Impact of Laryngopharyngeal Reflux on Occurrence and Clinical Course of Recurrent Respiratory Papillomatosis Via The Laryngoscope Objectives/Hypothesis Laryngopharyngeal reflux (LPR) has been proposed both as a trigger for recurrent respiratory papillomatosis (RRP) onset and as a factor favoring an aggressive clinical course. Study Design In this prospective study, 106 participants were recruited within a period of 24 months at the Department of Otorhinolaryngology and Cervicofacial Surgery, University Medical Centre Ljubljana. Methods This study compared a group of RRP patients (N = 36) with a group of LPR patients (N = 28) and a group of healthy participants (N = 42) based on Reflux Symptom Index (RSI), Reflux Finding Scores (RFS), and saliva analyses (pH, pepsin concentration, bile acid concentration, and pepsin enzymatic activity). Results The RRP group compared to the LPR group showed a statistically significant difference only in RSI and RFS scores, while the RRP group compared to healthy controls showed significantly higher values in all tested parameters (RSI score, RFS, saliva pH, pepsin concentration, bile acids concentration, pepsin enzymatic activity). Conclusions LPR is common in RRP patients and significantly more prevalent compared to healthy controls. Our results show that saliva analyses are a better office-based tool than RSI questionnaires and RFS scores for diagnosing LPR in RRP patients.
