Abstract
BACKGROUND: The use of acid-decreasing agents in the management of peptic ulcer haemorrhage continues to be controversial. Most clinical trials examining the efficacy of these drugs contain small numbers of patients, making it difficult to draw conclusions about their efficacy. METHODS: We report a meta-analysis that examined the effect of these drugs in the management of peptic ulcer haemorrhage. Included studies were located using a search of the Medline database between 1980 and 1999. Studies were published in English, randomized and controlled by a placebo group. Mantel-Haenszel and blinded random models were used in conducting the statistical processing of this meta-analysis. RESULTS: Twenty-one randomized placebo-controlled trials were included. The total number of patients was 3566 and the mean study size was 170 (range 20-1005). Seventeen of the papers assessed the efficacy of H2-antagonists, three assessed proton pump inhibitors and one was concerned with antacid therapy. The meta-analysis showed a significant reduction in re-bleeding rates (odds ratio, OR 0.727, 0.618-0.855, P < 0.001) and surgery rates (OR 0.707, 0.582-0.859, P < 0.001) when acid decreasing agents are used for acute peptic ulcer haemorrhage. Mortality rates appear to be unaffected (OR 1.140, 0.818-1.588, P=0. 49). CONCLUSIONS: This meta-analysis demonstrates a significant beneficial effect of acid-decreasing agents in lowering re-bleeding and surgery rates, but demonstrated no effect upon mortality.
