BACKGROUND: Helicobacter pylori infection is declining in developed and developing countries. The aim of this study was to retrospectively evaluate over an 8-year period the rate of H. pylori infection in children with gastrointestinal symptoms from Buenos Aires, Argentina. MATERIALS AND METHODS: We reviewed the records of children referred from 2002 to 2009 to the gastroenterology unit of the Children Hospital "Superiora Sor Maria Ludovica" for evaluation of upper gastrointestinal signs and symptoms in which the (13) C-urea breath test was performed to diagnose H. pylori infection and a sociodemographic questionnaire was obtained. RESULTS: Records of a total of 1030 children and adolescents with a mean age of 9.99 years were included in the analysis. We found an H. pylori prevalence of 41.2% (95% CI, 36.9-46.0%) for the triennium 2002-2004, dropping to 26.0% (95% CI, 20.7-31.8%) in the triennium 2007-2009. CONCLUSION: Our results showed a significant decrease in H. pylori infection rates from children referred for upper gastrointestinal symptoms evaluation from 2002 to 2009, following the H. pylori epidemiologic trend reported in other countries.
