Helicobacter pylori infection and occurrence of celiac disease in subjects HLA-DQ2/DQ8 positive: A prospective study.

Our study did not reveal any significant relationship between H. pylori and CD risk, even taking into account other confounders. More importantly, our findings do not support a "protective" role of H. pylori infection against CD, as previously reported. Therefore, there are no reasons to avoid eradication of H. pylori also in subject genetically susceptible for CD.
