The prevalence of Helicobacter pylori: are emergency medicine residents at risk?

Helicobacter pylori is strongly associated with peptic ulcer disease and gastric cancer. It is a cause of chronic active gastritis. Our hypothesis was that Emergency Physicians might be at increased risk for infection due to their exposure to gastric contents from procedures performed in the Emergency Department. Our goal was to test a group of Emergency Physicians for H. pylori infection. In this cross sectional study, we tested a group of volunteers from an Emergency Medicine residency program for H. pylori infection by serum analysis for IgG. A matched control group was also tested. Forty-five subjects were enrolled; one subject's sample was lost. Three of 44 subjects (6.8%) were positive for H. pylori antibodies. Seven of 44 controls (15.9%) tested positive. Thus, Emergency Physicians do not have increased H. pylori infection rates and may be at less risk than the general population. Routine testing is not recommended.
