Core Tip

Core Tip: This is a retrospective study to evaluate the association of Helicobacter pylori (H. pylori) infection and food-specific immunoglobulin G. We analyzed the data of 21822 subjects who underwent H. pylori infection assessment by the urea breath test and testing for food-specific immunoglobulin G of eggs, milk and wheat. The key finding was that H. pylori infection was associated with lower positivity for food-specific immunoglobulin G. If the negative correlation could be further confirmed and the mechanism could be clarified, it would provide some advisable suggestions for medical decisions regarding asymptomatic H. pylori infection.
