Background: Approximately 25% of adults regularly experience heartburn, a symptom of gastro-oesophageal reflux disease (GORD). Most patients are treated empirically (without specific diagnostic evaluation e.g. endoscopy. Among patients who have an upper endoscopy, findings range from a normal appearance, mild erythema to severe oesophagitis with stricture formation. Patients without visible damage to the oesophagus have endoscopy negative reflux disease (ENRD). The pathogenesis of ENRD, and its response to treatment may differ from GORD with oesophagitis., Objectives: Summarise, quantify and compare the efficacy of short-term use of proton pump inhibitors (PPI), H2-receptor antagonists (H2RA) and prokinetics in adults with GORD, treated empirically and in those with endoscopy negative reflux disease (ENRD)., Search Methods: We searched MEDLINE (January 1966 to November 2011), EMBASE (January 1988 to November 2011), and EBMR in November 2011., Selection Criteria: Randomised controlled trials reporting symptomatic outcome after short-term treatment for GORD using proton pump inhibitors, H2-receptor antagonists or prokinetic agents. Participants had to be either from an empirical treatment group (no endoscopy used in treatment allocation) or from an endoscopy negative reflux disease group (no signs of erosive oesophagitis)., Data Collection and Analysis: Two authors independently assessed trial quality and extracted data., Main Results: Thirty-four trials (1314 participants) were included: fifteen in the empirical treatment group, fifteen in the ENRD group and four in both. In empirical treatment of GORD the risk ratio (RR) for heartburn remission (the primary efficacy variable) in placebo-controlled trials for PPI was 0.37 (two trials, 95% confidence interval (CI) 0.32 to 0.44), for H2RAs 0.77 (two trials, 95% CI 0.60 to 0.99) and for prokinetics 0.86 (one trial, 95% CI 0.73 to 1.01). In a direct comparison PPIs were more effective than H2RAs (seven trials, RR 0.66, 95% CI 0.60 to 0.73) and prokinetics (two trials, RR 0.53, 95% CI 0.32 to 0.87).In treatment of ENRD, the RR for heartburn remission for PPI versus placebo was 0.71 (ten trials, 95% CI 0.65 to 0.78) and for H2RA versus placebo was 0.84 (two trials, 95% CI 0.74 to 0.95). The RR for PPI versus H2RA was 0.78 (three trials, 95% CI 0.62 to 0.97) and for PPI versus prokinetic 0.72 (one trial, 95% CI 0.56 to 0.92)., Authors' Conclusions: PPIs are more effective than H2RAs in relieving heartburn in patients with GORD who are treated empirically and in those with ENRD, although the magnitude of benefit is greater for those treated empirically.

Background: Approximately 25% of adults experience heartburn, the cardinal feature of gastro-oesophageal reflux disease (GORD), at least monthly. The evaluation and treatment of patients with suspected GORD is associated with a substantial economic burden. Most patients are treated empirically (without specific diagnostic evaluation). They include a wide range of underlying oesophageal injury. The severity of oesophageal injury can only be established in those who have undergone upper endoscopy. Patients without visible damage to the oesophagus have been referred to as having endoscopy negative reflux disease (ENRD). The pathogenesis of ENRD as well as its response to treatment may differ from GORD with oesophagitis., Objectives: Summarise, quantify and compare the efficacy of the short-term use of proton pump inhibitors (PPI), H2-receptor antagonists (H2RA) and prokinetics in adults with GORD, treated empirically and in those with endoscopy negative reflux disease (ENRD)., Search Strategy: We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2005), MEDLINE (January 1966 to December 2005), EMBASE (January 1988 to December 2005)., Selection Criteria: Randomised controlled trials focussing on symptomatic outcome after short-term treatment for GORD using proton pump inhibitors, H2-receptor antagonists or prokinetic agents. Studies were included provided that participants could be classified in the empirical treatment group (no endoscopy used in treatment allocation) or in the endoscopy negative reflux disease group (no endoscopic signs of erosive oesophagitis)., Data Collection and Analysis: Two reviewers independently assessed trial quality and extracted data., Main Results: Thirty-one trials (9457 participants) were included: fifteen in the empirical treatment group, twelve in the ENRD group and four in both. In empirical treatment of GORD the relative risk (RR) for heartburn remission (the primary efficacy variable) in placebo-controlled trials for PPI was 0.37 (two trials, 95% confidence interval (CI) 0.32 to 0.44), for H2RAs 0.77 (two trials, 95% CI 0.60 to 0.99) and for prokinetics 0.86 (one trial, 95% CI 0.73 to 1.01).

In treatment of ENRD, the RR for heartburn remission for PPI versus placebo was 0.69 (seven trials, 95% CI 0.62 to 0.78) and for H2RA versus placebo was 0.84 (two trials, 95% CI 0.74 to 0.95). The RR for PPI versus H2RA was 0.78 (three trials, 95% CI 0.62 to 0.97) and for PPI versus prokinetic 0.72 (one trial, 95% CI 0.56 to 0.92)., Authors' Conclusions: PPIs are more effective than H2RAs in relieving heartburn in patients with GORD who are treated empirically and in those with ENRD, although the magnitude of benefit is greater for those treated empirically.

Background: Heartburn affects 25% of the adult population on a monthly basis and represents the core symptom of gastro-oesophageal reflux disease (GORD). Treatment is readily available and puts a large demand on healthcare budgets. A majority of GORD patients show no endoscopic abnormalities and in daily practice most patients are treated empirically., Objectives: Summarise, quantify and compare the efficacy of the short-term use of proton pump inhibitors (PPI), H2-receptor antagonists (H2RA) and prokinetics in adults with GORD and endoscopy negative reflux disease (ENRD)., Search Strategy: We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2003), MEDLINE (January 1966 to December 2003), EMBASE (January 1988 to December 2003)., Selection Criteria: Randomised controlled trials focussing on symptomatic outcome after short-term treatment for GORD using proton pump inhibitors, H2-receptor antagonists or prokinetic agents. Participants had to be classifiable in the empirical treatment group (no endoscopy used in treatment allocation) or in the endoscopy negative reflux disease group (no endoscopic signs of erosive oesophagitis)., Data Collection and Analysis: Two reviewers independently assessed trial quality and extracted data., Main Results: Twenty-seven trials (8402 participants) were included: thirteen in the empirical treatment group, ten in the ENRD group and four in both. In empirical treatment of GORD the relative risk (RR) for heartburn remission in placebo-controlled trials for PPI was 0.37 (two trials, 95% confidence interval (CI) 0.32 to 0.44), for H2RAs 0.77 (two trials, 95% CI 0.60 to 0.99) and for prokinetics 0.86 (one trial, 95% CI 0.73 to 1.01). In a direct comparison PPIs were significantly (p < 0.05) more effective than H2RAs (five trials, RR 0.69, 95% CI 0.61 to 0.77) and prokinetics (two trials, RR 0.53, 95% CI 0.32 to 0.87). In treatment of ENRD, RR for heartburn remission for PPI versus placebo was 0.68 (six trials, 95% CI 0.59 to 0.78) and for H2RA versus placebo was 0.84 (two trials, 95% CI 0.74 to 0.95). The RR for PPI versus H2RA was 0.74 (three trials, 95% CI 0.53 to 1.03) and for PPI versus prokinetic 0.72 (one trial, 95% CI 0.56 to 0.92)., Reviewers' Conclusions: The findings in this review suggest that antisecretory drugs are effective in the empirical treatment of complaints likely to originate from GORD and in treatment of ENRD and furthermore that PPIs are superior to H2RAs in empirical treatment of typical GORD symptoms.

Objective: To investigate the efficacy of acid suppressant drugs in the empirical treatment of gastroesophageal reflux disease (GERD) and in the treatment of endoscopy-negative reflux disease (ENRD)., Design: medline, embase, and the Cochrane Controlled Trials Register were searched. Bibliographies were reviewed., Setting: Studies were eligible that compared the short-term use of proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs) with each other or with placebo in adults with GERD who were enrolled irrespective of endoscopic findings (empirical cases) or in whom endoscopy showed no signs of esophagitis (endoscopy-negative cases)., Measurements: Of 1,408 studies, only 13 could be included for meta-analysis. Data on 3,433 patients empirically treated for GERD and 2,520 patients treated for ENRD were extracted. The primary endpoint was relief of heartburn., Main Results: In the empirical treatment of GERD, the summary relative risk (sRR) for symptom relief from H2RAs versus placebo was 0.77 (95% confidence interval [95% CI], 0.60 to 0.99). RR in the only placebo-controlled PPI trial was 0.35 (95% CI, 0.26 to 0.46). The sRR for standard dose PPIs versus H2RAs was 0.55 (95% CI, 0.44 to 0.68). In treatment of ENRD, both PPIs (sRR, 0.64; 95% CI, 0.52 to 0.79) and H2RAs (sRR, 0.78; 95% CI, 0.62 to 0.97) were superior to placebo, and PPIs were superior to H2RAs (sRR, 0.81; 95% CI, 0.70 to 0.95)., Conclusions: Acid suppressant therapy (with a PPI or an H2RA) is more effective than placebo for short-term relief of heartburn in patients with persistent symptoms who are treated empirically for GERD and in those in whom esophagitis was excluded after endoscopy. The benefit of PPIs compared with H2RAs is more pronounced in patients treated empirically.

Bibliographies were screened., Selection Criteria: Included were randomised controlled trials focussing on symptomatic outcome after short-term treatment for GORD using proton pump inhibitors, H2-receptor antagonists or prokinetic agents. Participants had to be classifiable in the empirical treatment group (no endoscopy used in treatment allocation) or in the endoscopy negative reflux disease group (no endoscopic signs of erosive oesophagitis)., Data Collection and Analysis: Data from included trials were extracted by two reviewers independently. The impact of interventions was expressed as relative risks (RR) together with 95% confidence intervals (95% CI). Meta-analysis was only performed if there were sufficient trials of similar comparisons reporting the same outcomes. Relative risks were combined for binary outcomes., Main Results: Twenty-three trials were included: eleven in the empirical treatment group, nine in the ENRD group and three in both. In empirical treatment of GORD the RR for heartburn remission in placebo-controlled trials for PPI was 0.35 (1 trial, 95% CI 0.26 to 0.46), for H2RAs 0.77 (2 trials, 95% CI 0.60 to 0.99) and for prokinetics 0.86 (1 trial, 95% CI 0.73 to 1.01). In a direct comparison PPIs were significantly (p<0.05) more effective than H2RAs (3 trials, RR 0.67, 95% CI 0.57 to 0.80) and prokinetic's (2 trials, RR 0.53, 95% CI 0.32 to 0.87). In treatment of ENRD, RR for heartburn remission for PPI versus placebo was 0.66 (5 trials, 95% CI 0.55 to 0.80) and for H2RA versus placebo was 0.84 (2 trials, 95% CI 0.74 to 0.95). The RR for PPI versus H2RA was 0.69 (2 trials, 95% CI 0.39 to 1.20) and for PPI versus prokinetic 0.72 (1 trial, 95% CI 0.56 to 0.92)., Reviewer's Conclusions: The findings in this review suggest that antisecretory drugs are effective in the empirical treatment of complaints likely to originate from GORD and in treatment of ENRD and furthermore that PPIs are superior to H2RAs in empirical treatment of typical GORD symptoms, but not in treatment of ENRD.
