The impact of Helicobacter pylori eradication on peptic ulcer healing
Abstract
OBJECTIVE: Current literature was reviewed analyzing the outcome of peptic ulcer healing in relation to the results of the posttherapeutic Helicobacter pylori (HP) status.
METHODS: Literature was reviewed along with an analysis of 60 studies, comprising a total of 4329 patients.
RESULTS: Successful Helicobacter pylori eradication was found to induce a better response in peptic ulcer healing, regardless of diagnosis: gastric ulcer 88% vs 73% (odds ratio [OR] 2.7, p < 0.01), duodenal ulcer 95% vs 76% (OR 5.6, p < 0.0001), and peptic ulcer 95% vs 76% (OR 6.6, p < 0.0001), for patients having their HP infection successfully cured versus those remaining HP-positive, respectively (Fisher's exact test). For all evaluated time points (< or = 6, 7-8, and 10-12 wk after beginning treatment), HP-negative patients had higher healing rates than HP-positive patients (95% vs 82%, 94% vs 69%, and 96% vs 78% with corresponding OR of 4.2, 6.5, and 7.4, all p < 0.0001, Fisher's exact test). The use of concomitant acid suppression therapy during initial HP eradication provided a benefit on peptic ulcer healing only for patients with persistent HP infection (improved healing rates of 78% vs 67%; otherwise rates were 94-96%). Likewise, prolonged acid inhibition in HP treatment failures after the initial HP treatment phase resulted in 7-20% improved healing rates, whereas patients becoming HP-negative did not profit.
CONCLUSION: Successful HP eradication therapy accelerates peptic ulcer healing…
