Five hundred and sixteen adults with predominant heartburn symptoms of GERD were recruited from gastroenterologist and family physician practices and treated with 6 weeks of(More)
OBJECTIVE To evaluate the efficacy of acid-suppressive therapy with the proton pump inhibitor esomeprazole on the signs and symptoms of chronic posterior laryngitis (CPL) in patients with suspected reflux laryngitis. STUDY DESIGN Prospective, multicenter, randomized, parallel-group trial that compared twice-daily esomeprazole 40 mg with placebo for 16(More)
OBJECTIVES To establish the reliability, validity, and responsiveness of a new, disease-specific assessment tool, the LPR-HRQL, which assesses patient-reported outcomes (PRO) with regard to health-related quality of life (HRQL) of patients with laryngopharyngeal reflux (LPR). DESIGN A prospective, open-label, repeated-measures study. SETTING Six centers(More)
OBJECTIVES:Sleep disturbances are common in patients with gastroesophageal reflux disease (GERD). This study examined the effects of esomeprazole on nighttime heartburn, GERD-related sleep disturbances, sleep quality, work productivity, and regular activities.METHODS:This multicenter, randomized, double-blind, placebo-controlled trial included adults with(More)
BACKGROUND Medical treatments for gastro-oesophageal reflux disease (GERD) vary in their ability to completely resolve heartburn and other symptoms. Although GERD reduces health-related quality of life (HRQL) little is known about the relationship between resolution of heartburn symptoms with medical therapy and HRQL. We evaluated the association between(More)
BACKGROUND Nighttime heartburn, common among patients with gastro-oesophageal reflux disease (GERD), is associated with substantial clinical effects. GERD-related sleep disturbances are underappreciated and undertreated. AIM To evaluate the efficacy of esomeprazole on GERD-related nighttime heartburn and associated sleep disturbances.

The extent of impairment of health-related quality of life (HRQL)(More)
Severity and frequency of gastroesophageal reflux disease (GERD) related symptoms are associated with impaired health-related quality of life (HRQL). This study evaluated the association between baseline heartburn severity and endpoint HRQL of patients treated for heartburn and the relationship between complete resolution of heartburn symptoms and HRQL(More)
BACKGROUND Although most health-related quality of life questionnaires are self-administered by means of paper and pencil, new technologies for automated computer administration are becoming more readily available. Novel methods of instrument administration must be assessed for score equivalence in addition to consistency in reliability and validity. (More)
BACKGROUND The impact of gastro-oesophageal reflux disease on work productivity has become increasingly important, as the symptoms of gastro-oesophageal reflux disease affect individuals in their productive years of life.
