title: New Therapeutic Approaches to Peptic Ulcer Disease: The Role of Helicobacter Pylori.
abstract: One of the most common bacterial infections of human involves Helicobacter pylori, a spiral, gram-negative bacterium that is now thought to be a dominant factor in the development of peptic ulcer disease and may be significant in causing certain forms of gastric cancer. Almost 100% of patients with duodenal ulcer and 70 to 90% affected with gastric ulcer are infected with H. pylori. In order to achieve cure of H. pylori--induced ulcer disease, it is necesary to eradicate the bacterial infection. Mere suppression or clearance infection without eradication is associated with a >80% recurrence of the ulcer. The epidemiology, microbiology, and pathogenesis of H. pylori infections are reviewed. Diagnostic methods and optimal treatment strategies for H. pylori infections are examined. The most current diagnostic and treatment algorithms for peptic ulcer disease are discussed critically, and future directions for drug development aimed at eradication of H. pylori infection are considered.
