Summary

This study tests a 'screen and treat' approach for H. pylori infection in 14-18 year olds in Chile, where stomach cancer rates are high. Researchers will screen up to 1000 teens and randomly assign 210 persistently infected participants to receive antibiotics or no treatment. They aim to see if eradication reduces signs of stomach damage and changes gut bacteria, with the goal of preventing future cancer.
