  • Title: Study of outcome after targeted intervention for peptic ulcer resistant to acid suppression therapy.
    Author: Lanas A, Remacha B, Sáinz R, Hirschowitz BI.
    Journal: Am J Gastroenterol; 2000 Feb; 95(2):513-9. PubMed ID: 10685760.
    Abstract:
    OBJECTIVE: Different factors might affect outcome in ulcers resistant to antisecretory therapy. The aim of the study was to define the odds of resistant ulcers being associated with NSAID use, and/or Helicobacter pylori (H. pylori) infection, or neither. METHODS: A total of 80 patients with resistant peptic ulcers were prospectively followed after targeted intervention for a mean follow-up of 39.5+/-6.9 months. RESULTS: NSAID use was involved in 24 cases (14 with and 10 without concomitant H. pylori infection), H. pylori alone was involved in 44, and 12 patients had neither factor present. Of the NSAID group, resistant ulcers healed in patients who stopped taking NSAIDs. Those continuing to use NSAIDs (10 of 24; 41.6%) had either persistent ulceration or ulcer complications despite H. pylori eradication and omeprazole therapy. Of the H. pylori group, infection eradication induced ulcer remission in most patients, but those with persistent infection and a small subset of H. pylori eradicated patients (16.6%) had persistent/recurrent ulceration. Of the 12 refractory patients with neither NSAID use nor H. pylori infection, three had persistent ulceration but nine were controlled with antisecretory agents. Other factors (e.g., smoking or acid hypersecretion) were not associated with final outcome after targeted intervention of H. pylori infection and NSAID use. CONCLUSIONS: With current antiulcer therapies, NSAID use is the main, but not the exclusive, factor leading to intractability and complications in refractory ulcers. In a subset of resistant ulcers, neither the presence of H. pylori nor use of NSAIDs are involved. In this study, despite specific therapeutic intervention, 22.5% of patients with resistant ulcers had continuing ulcer problems.
