Association of Helicobacter pylori infection with type 2 diabetes

The last three decades have witnessed a rapid rise in the number of people with type 2 diabetes (T2DM), and China has the largest population of diabetes in the world. Patients with T2MD are more susceptible to a variety of infections due to impaired host immunity. Helicobacter pylori (H. pylori) hosted in the human stomach is the pathogen of a series of gastric and extragastric diseases, and has infected > 50% of the world population. H. pylori infection is rapidly becoming a serious threat to public health. Epidemiological surveys have indicated an obvious relationship between H. pylori and diabetes. H. pylori infection in T2MD cases can induce systemic inflammation, increase the risk of diabetic nephropathy and retinopathy, and is associated closely with the micro- and macro-vascular complications. Chronic H. pylori infection may have a harmful impact on pancreatic β-cells and may be a risk factor for T2MD and insulin resistance. Treatment of H. pylori infection and control of T2MD are becoming increasingly challenging due largely to the huge population of patients with the two diseases and to the relative complexity of treatment regimens. Further clinical and basic studies are needed to control H. pylori infection and T2MD effectively.
