H. pylori, lipid loss and stomach cancer

H. pylori infection — a strong risk factor for stomach cancer — changes the composition of stomach lipids, which could offer new biomarkers for detecting premalignant changes, Vanderbilt researchers discovered.

Study finds genetic factor undermines H. pylori treatment

Helicobacter pylori, a stomach-dwelling bacterium, is a strong risk factor for gastric cancer, peptic ulcers and other debilitating gastrointestinal disorders. Yet efforts to eradicate it using a combination of antibiotics and proton pump inhibitors (PPIs), which suppress gastric acid production, often fail.

Factor involved in stomach injury response identified

Researchers at Vanderbilt University Medical Center have identified a key factor that coordinates the body’s repair response to severe injury in the stomach caused, most commonly, by infection by the bacterium Helicobacter pylori.
