NCT00364104

Brief Summary

The investigators hypothesize that the Helicobacter pylori bacterium decreases iron from the stomach and that this effect of the infection can be identified among persons with iron deficiency as well as among persons with normal iron stores. The aim of this study is to determine whether Helicobacter pylori eradication in children is followed by an increase in markers of iron stores after six to twelve months of treatment.
