Purpose
Population-based Helicobacter pylori (H. pylori) screening and eradication for adults in areas with a high incidence of gastric cancer have been shown to be effective. The current status of H. pylori screening for young people, however, has not been sufficiently evaluated.
Methods
A systematic review of population-based H. pylori screening of young people was performed using four databases (MEDLINE, EMBASE, the Cochrane Library, and ICHUSHI) and independently evaluated by two investigators. Studies were evaluated with regard to the country, region, screening method, target age, number of screened people, and rate of positive screening.
Results
From 3231 studies, 39 studies were included (14 English original studies published in peer-review journals, 6 Japanese original studies, and 19 conference reports). These studies originated from 10 countries, with the largest number stemming from Japan (29 studies) followed by Germany (2 studies). Screening was performed using the urea breath test, blood antibodies, stool antigens, and urine antibodies. Five countries used the breath test as the first screening method, five used blood samples, two used stool antigens, and only Japan used urinary tests.
Conclusion
Screening for H. pylori in young people was reviewed based on reports from several countries, and findings suggest that local authorities considering screening for H. pylori in young people need to scrutinize the age and potential methods. Further research is required to determine the effectiveness of mid- to long-term H. pylori screening for young people.
