INFECTION WITH HELICOBACTER PYLORI (Group 1) For definition of Groups, see Preamble Evaluation VOL. : 61 (1994) (p. 177) 5. Summary of Data Reported and Evaluation 5.1 Exposure data Helicobacter are spiral, flagellated, gram-negative bacteria that colonize the gastrointestinal tract of human beings and animals. H. pylori is restricted to human gastric mucosa and can infect some other primates. H. pylori strains are genetically heterogeneous, and this attribute is useful in studies of transmission. H. pylori can be cultured, is sensitive to most antibiotics in vitro and is characterized by very strong urease activity. Colonization of the gastric mucosa and subsequent development of gastritis are dependent on bacterial factors, including motility, potent urease activity and specific adherence to gastric epithelium. H. pylori can be detected in gastric biopsy specimens and indirectly by serology and analysis of breath after ingestion of labelled urea. Standard histological and bacteriological techniques, the polymerase chain reaction and indirect tests are highly sensitive. The rapid urease test on biopsy specimens is practical but less sensitive. Epidemiological studies currently involve use of serological tests and mainly commercially available enzyme-linked immunosorbent assay kits. H. pylori

Helicobacter Pylori (H. pylori) "The Ulcer Bug" What is Helicobacter Pylori? How does it survive the stomach acid? What are the diseases linked to H Pylori? How does one detect H Pylon? ... How is H Pylori treated? As you might have heard by now, ulcers in your stomach and duodenum (peptic ulcers) are not caused by your boss or by stress but by a bacterium (bug) living in your stomach. Ignored for centuries the rediscovery of this bacterium by two Australian doctors Warren and Marshall has been one of the most exciting things to happen in the field of Gastroenterology (GI). Lore has it that in the 1980's Dr. Marshall was asked at a GI meeting "Are you proposing that H pylori causes some ulcers? (sarcasm). He replied "No, I am proposing that H pylori causes all ulcers!". Actually, the truth lies somewhere in between. (top) What is Helicobacter Pylori? The name says it all. It is a wavy, spiral bacterium that lives in or near the pylorus (a part of the stomach). Man is the only known host so far. It is transmitted from person to person by contamination of food, utensils and instruments. It is much more common in the developing world where almost all adults are infected. In the U.S. infection is uncommon before age 30 and becomes more common as one grows older. It is more common in lower socioeconomic groups. Its incidence seems to be declining in the western world, mainly because of improved sanitation and hygiene.

H. pylori is a spiral-shaped bacterium found in the stomach, which (along with acid secretion) damages stomach and duodenal tissue, causing inflammation and peptic ulcers. How does H. pylori cause damage? History of Helicobacter Pylori In 1982, Australian researchers Barry Marshall and Robin Warren discovered spiral-shaped bacteria in the stomach, later named Helicobacter pylori (H. pylori). After closely studying H. pylori's effect on the stomach, they proposed that the bacteria were the underlying cause of gastritis and peptic ulcers. In their studies, all patients with duodenal ulcers and 80 percent of patients with stomach ulcers had the bacteria. The 20 percent of patients with stomach ulcers who did not have H. pylori were those who had taken NSAIDs (such as aspirin and ibuprofen) which are a common cause of stomach ulcers. Although the findings seem conclusive, Marshall and Warren's theory was debated and disputed for some time. However, further evidence linking H. pylori to ulcers mounted over the next 10 years as numerous studies from around the world confirmed its presence in most people with ulcers. Researchers from the United States and Europe proved that using antibiotics to eliminate H. pylori healed ulcers and prevented recurrence in about 90 percent of cases.

For Patients Cancer Prevention Tips from the University of Iowa's Cancer Information Service in the Holden Comprehensive Cancer Center Helicobacter Pylori Peer Review Status: Internally Reviewed First Published: January 2003 Last Revised: April 2003 Helicobacter pylori (H. pylori) is a germ that can cause ulcers. In fact, H. pylori is responsible for the majority of duodenal and stomach ulcers. There is now strong evidence that H. pylori increases the risk of stomach cancer and MALT lymphoma, a rare form of stomach cancer. If an H. pylori infection is present for a long time, it can lead to chromic inflammation of the stomach's inner layer, which can lead to chronic atrophic gastritis, a condition that is considered precancerous. How do you know if you have H. pylori? About 20% of people under 40 years of age, and half of those over 60 are infected with H. pylori. Most infected people, however, do not develop ulcers or gastritis. Some people experience only very mild symptoms, or none at all. Symptoms of ulcers are: Dull, gnawing ache

Home Search Spleen Cells Eradicate Helicobacter Pylori Infection A new study in mice suggests that a treatment using a specific type of immune cell can eradicate the ulcer-causing bacteria Helicobacter pylori. The research found that mice with deficient immune systems completely recovered from infections with H. pylori after they were treated with healthy spleen cells. After that treatment, no trace of the bacteria was found in the stomachs of these mice. "These mice initially had a quick and severe reaction to the ulcer-causing bacteria," said Kathryn Eaton, a study co-author and an associate professor of veterinary biosciences at Ohio State University. "But the reaction was completely reversed in a matter of months, and the bacteria also disappeared." The research appears in a recent issue of the journal Infection and Immunity . Eaton co-authored the study with Megan Mefford, a research assistant at Ohio State. Scientists know that H. pylori causes stomach ulcers in humans. The body typically responds to the bacterial infection with a condition called gastritis, an inflammation of the stomach lining. Antibiotics help control the growth and spread of the bacteria, but medication doesn't always completely eliminate it. And while gastritis may help control H. pylori levels, it can also damage the stomach.

Browse by Review Group A substantive amendment to this systematic review was last made on 12 October 2002. Cochrane reviews are regularly checked and updated if necessary. Background: Helicobacter pylori (H pylori) is the main cause of peptic ulcer disease. The role of H pylori in non-ulcer dyspepsia is less clear. Objectives: To determine the effect of H pylori eradication on dyspepsia symptoms and quality of life scores in patients with non-ulcer dyspepsia. Search strategy: Trials were identified through electronic searches of the Cochrane Controlled Trials Register (CCTR), MEDLINE, EMBASE, CINAHL and SIGLE, using appropriate subject headings and keywords, searching bibliographies of retrieved articles, and through contacts with experts in the fields of dyspepsia and with pharmaceutical companies. Selection criteria: All parallel group randomised controlled trials (RCTs) comparing drugs to eradicate H pylori with placebo or other drugs known not to eradicate H pylori for patients with non-ulcer dyspepsia.

From Helicobacter Pylori to Peptic Ulcer to Gastric Cancer Peptic ulcer is the most common chronic illness of the digestive system causing on-and-off symptoms of upper abdominal pain, fullness, gas and bloating. In some patients, it may also give rise to serious complications such as bleeding, bowel perforation, and obstruction. Ulcer bleeding (fig.1) is one of the most common reasons for emergency hospital admission and the incidence of this condition in Hong Kong tops the list in the whole world. Fig. 1 Peptic ulcer seen under endoscopy Acid - the Culprit of Peptic Ulcers? A German physician so stated a century ago: 'No acid, no ulcer.' The treatment of peptic ulcers has for a long time been concentrated on suppressing acid secretion in the stomach by long-term medication or surgery. Potent and expensive ulcer healing drugs have been developed which merely suppress acid secretion without changing the natural history of the disease. Once medication is discontinued, ulcers invariably recur within a few months. Helicobacter Pylori (HP) Closely Associated with the Disease In 1983, researchers in Australia discovered a bacterium residing in the stomach of patients with chronic gastritis (inflammation of the stomach). Further studies showed that this bacterium, subsequently called
