Characterisation of laryngo-pharyngeal reflux disease in old and ageing patients

OBJECTIVES:
To characterize laryngo-pharyngeal reflux (LPR) in patients over 60 years of age.

METHODS:
Retrospective review of patients over 60 years of age with symptoms suspicious of LPR, seen from 2005 to 2014 at an ENT Department of an academic hospital. Eighty-five consecutive patients (54 females, 31 males) who had completed a dual-sensor 24-hour pH-metry were included (considered "gold-standard" in LPR diagnosis).

Body mass index, and reflux information and interventions were revised. pH-metries were evaluated according to DeMeester & Johnson's criteria. Symptoms were assessed according to the Reflux Symptom Index (RSI) and classified as abnormal if score was ≥13. A naso-fibro-laryngoscopy enabled findings to be documented according to the Reflux Finding Score (RFS), and they were classified as abnormal if the score was ≥7.

RESULTS:
The patients' mean age was 67 years. A positive pH-metry was present in 70 patients (82.5%). Fifty patients (59%) had abnormal body mass index, and almost 90% of them had an abnormal pH-metry. Mean RSI score was 9.8, with abnormal results in 24 patients (28%). Only 20 patients (23%) with abnormal RSI had a positive pH-metry.

Posterior commissure hypertrophy was the most common finding (90% of patients). Mean RFS score was 9.07, with abnormal results in 69 patients (81%). Sixty-one patients (70%) with abnormal RFS had a positive pH-metry. Only 18 patients (20%) had coincidental abnormal pH-metry, RSI, and RFS.

CONCLUSIONS:
In ageing patients, abnormal body mass index is strongly associated with abnormal pH-metry. RSI is a weak indicator of LPR, whereas RFS has a moderate value.
