SummaryAntibiotics vs. acid suppression therapy (with or without long-term maintenance acid suppression therapy) for the prevention of recurrent bleeding from peptic ulcerPeptic ulcers are caused by acidic stomach juices damaging the lining of the stomach (gastric ulcer) or upper small intestine (duodenal ulcer). This causes pain, indigestion and sometimes bleeding. Bleeding in the gut can be life-threatening. Several treatments aim to heal the ulcer and prevent future bleeding. These include acid-suppressing drugs and antibiotics to treat Helicobacter pylori, a bacterium that causes most peptic ulcers. The review found that, for people who have had a bleeding peptic ulcer caused by Helicobacter pylori, treatment with antibiotics more effectively prevents gastrointestinal re-bleeding than acid-suppressing drugs. Antibiotics when Helicobacter pylori infection is present are also cheaper and more convenient than long-term acid-suppressing drugs.

October 20. 2003 AbstractBackgroundPeptic ulcer is the main cause for upper gastrointestinal haemorrhage, and Helicobacter pylori (H.pylori) infection is the main etiologic factor for peptic ulcer disease. Maintenance antisecretory therapy is the standard long-term treatment for patients with bleeding ulcers to prevent recurrent bleeding. The efficacy of H. pylori eradication for the prevention of rebleeding from peptic ulcer is unknown. ObjectivesTo compare the efficacy of H. pylori eradication therapy vs. antisecretory non-eradication therapy (with or without long-term maintenance antisecretory therapy) for the prevention of recurrent bleeding from peptic ulcer. Search strategyWe searched the Cochrane Controlled Trials Register (the Cochrane Library issue 4, 2003), MEDLINE (January 1966 to January 2004), EMBASE (January 1988 to January 2004), CINAHL (January 1982 to January 2004), and reference lists of articles. We also conducted a manual search from several congresses. The search strategy was re-run in January 2005 and October 2008, but no new trials were found. Selection criteriaControlled clinical trials comparing the efficacy of H. pylori eradication therapy vs. antisecretory non-eradication therapy (with or without long-term maintenance antisecretory therapy) for the prevention of recurrent bleeding from peptic ulcer. Data collection and analysisData extraction and quality assessment of studies was done by two reviewers. Study authors were contacted for additional information. Main resultsSeven studies with a total of 578 patients were included in the first comparison: mean percentage of rebleeding in H. pylori eradication therapy group was 2.9%, and in the non-eradication therapy group without subsequent long-term maintenance antisecretory therapy it was 20% (OR 0.17, 95% CI 0.10 to 0.32; there was no statistical evidence of heterogeneity; NNT was 7, 95% CI 5 to 11). Three studies with a total of 470 patients were included in the second comparison: mean percentage of rebleeding in H. pylori eradication therapy group was 1.6%, and in non-eradication therapy group with long-term maintenance antisecretory therapy it was 5.6% (OR 0.24, 95% CI 0.09 to 0.67; heterogeneity was not demonstrated; NNT was 20, 95% CI 12 to 100). Subgroup analyses were carried out to examine the effect of NSAIDS and of excluding H.pylori eradication failures from the analyses. Authors' conclusionsTreatment of H. pylori infection is more effective than antisecretory non-eradication therapy (with or without long-term maintenance antisecretory therapy) in preventing recurrent bleeding from peptic ulcer. All patients with peptic ulcer bleeding should be tested for H. pylori infection, and eradication therapy should be prescribed to H. pylori-positive patients. |
