The efficacy of proton-pump inhibitors in acute ulcer bleeding: a qualitative review
Abstract
Despite remarkable progress in the treatment of chronic peptic ulcer disease, acute gastroduodenal ulcer hemorrhage remains a therapeutic challenge. Numerous trials of H-2 receptor antagonists have not consistently shown a significant benefit in such patients. Proton-pump inhibitors, which more profoundly suppress gastric acid, are being increasingly evaluated. We have performed a qualitative systematic review to analyze the results of these trials to determine if a reasonable consensus can be reached. We searched for all published, randomized, controlled studies that evaluated proton-pump inhibitors in patients with acute peptic ulcer hemorrhage. The primary outcomes evaluated were: (A) persistent or recurrent bleeding; (B) need for surgery; and (C) mortality. Sixteen trials were evaluated, enrolling 3154 patients. Four of the sixteen studies showed a statistically significant decrease in overall rebleeding rate, and two described specific benefit in patients with Type IIa and IIb endoscopic stigmata. Four studies also showed a significantly decreased surgery rate, but none demonstrated a significant mortality reduction. Proton-pump inhibitors may improve outcome in acute peptic ulcer bleeding, but the available clinical data remain inconsistent. Further study is necessary to define the optimal dosage, route of administration, duration of therapy, and subsets of patients most likely to benefit.
