High risk of failing eradication of Helicobacter pylori in patients with diabetes: a meta-analysis.

Aims: Eradication of Helicobacter pylori (HP) is an effective approach to improve intestinal symptoms and prevent gastric cancer. However, there has been concern that the presence of diabetes reduces the effectiveness of antibiotics. We performed this meta-analysis to investigate the effect of diabetes on the risk of failing eradication in patients with diabetes.
