Abstract
Helicobacter pylori leads to chronic gastritis, peptic ulcer disease and gastric cancer. With increasing issues of antibiotic resistance and changing epidemiology of this pathogen, new approaches are needed for effective management. In 1984, Dr Barry Marshall and Dr Robin Warren reported the association of Helicobacter pylori with peptic ulcers in The Lancet--a discovery that earned them the Nobel prize in Physiology or Medicine in 2005--but what progress have we made since then? Here, we have invited three international experts to give their insights into the advances in H. pylori research over the past 30 years and where research should be focused in the future.
