BACKGROUND: There is little information on the prevalence of pathological sleep disorders in patients with gastro-oesophageal reflux disease and whether pharmacological treatment of patients with gastro-oesophageal reflux disease will lead to improvement in sleep. AIMS: This pilot study determined the prevalence of sleep disorder in patients with erosive gastro-oesophageal reflux disease, correlated subjective (questionnaire) and objective (actigraphy - a watch worn on the wrist that monitors motion to help differentiate sleep from awake states) assessment of sleep dysfunction and determined whether therapeutic resolution of oesophageal symptoms was associated with an improvement in sleep. METHODS: Eighteen patients with erosive gastro-oesophageal reflux disease received esomeprazole 40 mg once daily for 8 weeks. Assessments at 0, 4 and 8 weeks included: Gastrointestinal Symptoms Rating Scale, Pittsburgh Sleep Quality Index questionnaire and ambulatory wrist actigraphy. RESULTS: Unrecognized sleep disturbance occurred in 81% of this cohort of patients with gastro-oesophageal reflux disease and erosive oesophagitis. Median reflux syndrome score (heartburn and acid regurgitation) on Gastrointestinal Symptoms Rating Scale decreased from 2 at baseline to 0 at weeks 4 and 8 (P </= 0.0001). Median global Pittsburgh Sleep Quality Index score decreased from 8.50 at baseline to 4.50 at week 4 (P = 0.002) and to 7.00 at week 8 (P = 0.043). There were no significant changes in actigraphy measurements. CONCLUSIONS: Sleep disturbance is common in patients with gastro-oesophageal reflux disease with erosive oesophagitis. This study which is the first to evaluate sleep abnormalities and gastro-oesophageal reflux disease using a validated questionnaire, demonstrates that in patients with gastro-oesophageal reflux disease, sleep improvement, may be effected by gastro-oesophageal reflux disease therapy. Actigraphy may be inappropriate for measurement of sleep disturbance in gastro-oesophageal reflux disease patients.
