Helicobacter pylori Infection News and Research

RSS

Helicobacter pylori (H. pylori) is a type of bacteria. Researchers believe that H. pylori is responsible for the majority of peptic ulcers. H. pylori infection is common in the United States. About 20 percent of people under 40 years old and half of those over 60 years have it. Most infected people, however, do not develop ulcers. Why H. pylori does not cause ulcers in every infected person is not known. Most likely, infection depends on characteristics of the infected person, the type of H. pylori, and other factors yet to be discovered. Researchers are not certain how people contract H. pylori, but they think it may be through food or water. Researchers have found H. pylori in the saliva of some infected people, so the bacteria may also spread through mouth-to-mouth contact such as kissing.

Cases of stomach cancer to fall over next decade

New cases of stomach cancer are set to plummet a further 25 per cent in the West over the next decade, indicates research published ahead of print in the journal Gut .

Diets high in salt may increase stomach ulcers

Scientists from the Uniformed Services University of the Health Sciences (USU) have discovered that diets high in salt may increase the virulence of the pathogen Helicobacter pylori (H. pylori), which is the most common cause of ulcers in the stomach and duodenum.

High salt intake increases gene activity in the ulcer-causing bacterium Helicobacter pylori

Scientists have identified yet another risk from a high-salt diet. High concentrations of salt in the stomach appear to induce gene activity in the ulcer-causing bacterium Helicobacter pylori, making it more virulent and increasing the likelihood of an infected person developing a severe gastric disease.

Bovine protein called lactoferrin aids in treatment of gastrointestinal disorder

Recent evidence suggests that therapy currently used to treat Helicobacter pylori (H. pylori) infection, a major cause of upper gastrointestinal disorders, is unsuccessful in around 25 percent of cases.

University of Nottingham tackles Helicobacter pylori

The occurrence of the disease is currently thought to be due to several factors including the toxic nature of the infecting strain, the genetic susceptibility of the host, and environmental factors.

Stomach bacteria may protect against asthma

Researchers have found that a bacteria found in the stomach, that can cause cancer and peptic ulcers, may have a role in protecting children from asthma.

Study links Helicobacter pylori to asthma prevention

The stomach bacterium Helicobacter pylori, which causes stomach cancer and peptic ulcers, may not be all bad.

Helicobacter pylori increases risk of lower stomach cancer, decreases risk of upper

The bacteria Helicobacter pylori substantially increase the risk of cancer in the lower stomach, but it may decrease the risk of cancer near the junction between the esophagus and the stomach, according to a study in the October 19 Journal of the National Cancer Institute.

New understanding of how cells defend themselves

Biologists at the EPFL (Ecole Polytechnique Federale de Lausanne) have unveiled a new twist in a metabolic pathway that cells use to defend themselves against toxins made by disease-causing bacteria.

FDA warns against use of "bismacine," also known as chromocine

The U.S. Food & Drug Administration (FDA) is warning consumers and health care providers not to use a product called "bismacine," also known as chromocine.

Dieting may not help cancer patients

One study, a meta-analysis of 59 trials, found little evidence that diet is associated with survival or prognosis.

Levofloxacin-based triple therapy against persistent ulcer-inducing bacteria successful

For those who suffer from stomach ulcers, the daily routine of breakfast, lunch and dinner can be painful.

Bacterial binding in the stomach

Scientists have determined that decay-accelerating factor (DAF), a protein found in epithelial cells in the stomach, acts as a receptor for the bacteria Helicobacter pylori. Blocking this interaction could lead to new drugs that reduce the risk of peptic ulcer disease or gastric cancer.

New treatment against persistent ulcer-inducing bacteria successful

For those who suffer from stomach ulcers, the daily routine of breakfast, lunch and dinner can be painful. A common cause of these ulcers, as well as other gastric malignancies, is a bacterium called Helicobacter pylori .

Low doses of aspirin increase chance of developing ulcers

Aspirin has long been hailed as one of the most effective, low-cost ways to help guard against a heart attack or stroke. However, international medical researchers caution that low doses of aspirin also increase a patient's chance of developing an ulcer, often without warning signs.

Fundamental insight about protein evolution

While searching for new targets for malaria drugs and vaccines, a team including a Howard Hughes Medical Institute (HHMI) medical student fellow reached a fundamental insight about evolution: different species make use of similar sets of proteins in different ways.

The role of antigenic drive and tumor-infiltrating accessory cells in the pathogenesis of Helicobacter-induced MALT lymphoma

Research led by Dr. Anne Mueller at Stanford University School of Medicine demonstrates that successful eradication of Helicobacter may not prevent future aggressive gastric lymphoma since resting B cells are left behind.
