Abstract

BACKGROUND: The effect of gastro-oesophageal reflux on sleep and sleep quality is highly controversial.

AIM: To determine the temporal relationship of abnormal objective sleep parameters to gastro-oesophageal reflux during acid suppression in patients with self diagnosed sleep disorders.

METHODS: Polysomnography during oesophageal pH monitoring was conducted in 16 subjects with and without gastro-oesophageal reflux as determined by a standardized questionnaire. Subjects were studied before and after omeprazole.

RESULTS: All reflux events were followed by a sleep arousal or awakening. Nocturnal acid reflux events were not predicted by the Carlsson score. Omeprazole reduced acid reflux-associated arousals from 11.6 +/- 3.8 to 1.5 +/- 0.8 (P < 0.01) and awakenings from 7.7 +/- 1.2 to 3.7 +/- 0.5 (P < 0.05). Sleep efficiency improved from 70.2% to 81.6% in a small subset of subjects with decreased sleep (P < 0.05); rapid eye movement sleep increased from 55.0 +/- 4.5 to 94.5 +/- 18.9 min (P < 0.05); total sleep time increased from 294.0 +/- 15.9 to 345.6 +/- 55.6 min (P < 0.05). Apnoea, hypopnoea and hypoxaemia were not associated with reflux.

CONCLUSIONS: In subjects with gastro-oesophageal reflux, sleep arousals and awakenings are closely related to acid reflux events. Reflux-related arousals and awakenings are decreased by acid suppression. Acid suppression in selected subjects with reflux events and reduced sleep efficiency is associated with increased total sleep time, rapid eye movement sleep and sleep efficiency.
