title: Diagnosis of Helicobacter pylori.
abstract: In view of its potential risk for the development of gastrointestinal disease or even gastric cancer at a later age, the study of Helicobacter pylori infection in childhood is gaining increasing importance and H. pylori infection is being considered a major issue of public health. H. pylori infection can be detected by a variety of methods. Because of its easy use, affordability, and overall availability, serology is the preferred diagnostic test, especially for large epidemiological studies. Based on our results, one might consider treating a child with recurrent abdominal pain and positive serology for H. pylori without further work-up, and only perform additional investigations when an anti-H. pylori therapy fails to resolve the complaints. According to this proposition, endoscopy of the upper gastrointestinal tract remains indicated in children if the noninvasive tests for Helicobacter pylori are negative in the absence of a diagnosis, or if symptomatology persists despite treatment.
