Brief summary

The trial tends to evaluate the efficacy of vonoprazan-based triple therapy in eradicating H. Pylori infection in adolescent patients in Egypt, in comparison to standard treatment regimens to determine if it offers superior eradication rates (VONTAPE trial).

Detailed description

The VONTAPE trial will compare two treatment regimens for Helicobacter pylori eradication among adolescent patients presented to the gastroenterology department in an Egyptian institute. the eligible subjects will be randomly assigned to one of the two protocols (vonoprazan based vs. proton pump inhibitor-based triple therapy) for two weeks. then the eradication rates will be compared between the two study groups to see if there is a difference in efficacy. The currently available eradication regimens in our country show a low to intermediate eradication rate (50-75%). At the same time, H. pylori infection is prevalent. Recently, the FDA approved vonoprazan-based regimens for adult H. pylori infection with high eradication rates even in the settings of clarithromycin antibiotic resistance. In the VOTSAPE trial, we will test this efficacy in the \< 18 years adolescents.
