Systematic review: The global incidence and prevalence of peptic ulcer disease

Background Peptic ulcer disease (PUD) is most commonly associated with Helicobacter pylori infection and the use of acetylsalicylic acid (ASA) and nonsteroidal anti-inflammatory drugs (NSAIDs). The management of H. pylori infection has improved radically in recent years; however, the prescription of ASA and NSAIDs has increased over the same period. Aim To evaluate the current global incidence and prevalence of PUD by systematic review of the literature published over the last decade. Methods Systematic searches of PubMed, EMBASE and the Cochrane library. Results The annual incidence rates of PUD were 0.10-0.19% for physician-diagnosed PUD and 0.03-0.17% when based on hospitalization data. The 1-year prevalence based on physician diagnosis was 0.12-1.50% and that based on hospitalization data was 0.10-0.19%. The majority of studies reported a decrease in the incidence or prevalence of PUD over time. Conclusions Peptic ulcer disease remains a common condition, although reported incidence and prevalence are decreasing. This decrease may be due to a decrease in H. pylori-associated PUD.
