Helicobacter Pylori Gastritis
Alternate Names : Helicobacter Pylori Definition Helicobacter pylori (H. pylori ) is a bacterial organism responsible for most ulcers and many cases of chronic gastritis (inflammation of the stomach). This organism can weaken the protective coating of the stomach and duodenum (first part of the small intestines) and allow the damaging digestive juices to irritate the sensitive lining of these body parts. Interestingly, many people have this organism in their gastrointestinal tract but don't get an ulcer or gastritis. It seems that other factors must also be present for the damage to take place.

the ever popular cause for peptic and duodenal ulcers since its discovery by two Australian doctors,
Robin Warren, M.D., and Barry Marshall, M.D., in the early 80's.  Some doctors place the bacterium's
involvement as high as 90%, however ulcer-inducing drugs, alcohol, and other lifestyle stimulants are
still a more common factor in the development of these ulcers than given credit lately.
H. Pylori may be inhibited by raising stomach acid or lowering its pH, provided this is done before
much damage is done by the bug.  This is the reason why people who manage to maintain normal
stomach acid levels are generally asymptomatic and don't get ulcers unless they are taking specific
drugs, they consume excessive amounts of alcohol (although alcohol itself inhibits Helicobacter Pylori),
or they supplement too much calcium and magnesium, which in turn can lower stomach acid levels too much.  Coffee consumption is another factor known to aggravate the symptoms of H. Pylori infections.

Update on Helicobacter Pylori
Helicobacter Pylori is probably the most common bacterial infection worldwide. It is the cause of chronic type B gastritis and associated with duodenal ulcer, gastric ulcer, MALT (mucosa associated lymphoid tissue) lymphoma and gastric cancer . It is the causative agent in 95% of duodenal ulcer and 60-80% of gastric ulcers. Eradication reduces the recurrence rate from 80% to 4% yearly.
Pathophysiology
Most patients develop a chronic superficial antral gastritis and remain asymptomatic throughout their life. In some, the gastritis leads to elevated gastrin levels which increases acid output by parietal cells and leads to duodenal ulcer. In others, the gastritis progresses to a multifocal atrophic pan gastritis, with loss of gastric secretory capacity, and the development of gastric cancer. In a very small proportion, the lymphoid reaction to H. Pylori progresses to become a MALT lymphoma, probably cured by eradication of the organism. The various outcomes are thought to be influenced by the heterogeneity and virulence of the organism, host factors such as HLA genotype and immune response and the age of acquisition.
Testing
Testing for H. Pylori can be carried out by Biopsy, Breath test or Antibody tests. Biopsy samples may be examined by histology, culture, or by a rapid urease test.

HELICOBACTER PYLORI What is Helicobacter pylori Helicobacter pylori H. pylori ) is a spiral shaped bacterium that lives in or on the lining of the stomach. It causes more than 90 percent of ulcers, which are sores in the lining of the stomach or the duodenum (the first part of the small intestine). Before 1982, when this bacterium was discovered, spicy food, acid, stress and lifestyle were considered the major causes of ulcers. Since it is now known that most ulcers are caused by an infection with H. pylori , they can be cured with appropriate antibiotics. How common is H. pylori About two-thirds of the world's population is infected with H. pylori . In the United States, H. pylori is found more often in older adults, African Americans, Hispanics and lower socioeconomic groups. What illness can H. pylori cause? Most persons who are infected with H. pylori never have any symptoms or problems related to this infection; however, H. pylori can cause gastritis (inflammation of the lining of the stomach) or ulcers of the stomach or duodenum. About 25 million Americans suffer from ulcers. What are the symptoms of ulcers?

Helicobacter pylori Infection The medical community currently believes that the majority of stomach ulcers are due to infection with the bacterium Helicobacter pylori, rather than excessive acid secretion. The organism lives under the mucus layer lining the stomach, but does not actually invade the mucosa. In this manner, the organism protects itself from acid and pepsin secretions of the stomach. H. pylori further protects itself by secreting urease, an enzyme that breaks down urea into ammonia and carbon dioxide, the ammonia in turn neutralizing stomach acid. The activities of the organism cause a thinning and breakdown of the mucosal layer. The stomach lining is now exposed to acid and pepsin, and ulcers may develop. In these cases, stomach acid is a contributing factor, but not a cause of the ulcers.

It is almost universally accepted that H. pylori causes chronic gastritis and peptic ulcer disease, and the evidence that the infection also causes gastric adenocarcinoma is virtually unassailable. In high-risk populations, at least, prevention of gastric cancer by H. pylori eradication is theoretically feasible, although convincing clinical-trial evidence is lacking. However, perhaps because the incidence of gastric cancer is steadily declining in developed nations (and because H. pylori infection seems to be much less often acquired these days), interest in its prevention remains remarkably low key. Australian Aboriginals and Torres Strait Islanders are much more likely to suffer ill health and die at a younger age than non-Indigenous Australians.

Ulcer Symptoms and Helicobacter pylori
Frederick R. Jelovsek MD
Before 1982, we used to think that ulcers were caused by spicy food, acid, stress and the "Type A" personality. Then a bacterium called Helicobacter pylori was discovered. Now we know that up to 80% of stomach ulcers and 90% of duodenal ulcers are caused by the bacterium, H. pylori. As a result, ulcers are often cured now by medical therapy rather than surgical therapy. The Center for Disease Control and Prevention now puts out a fact sheet for health care providers to make sure the message is out that this is often a curable problem. From this July 1998 Fact Sheet and the H. pylori web site that is maintained by the CDC, we can learn the answers to several questions about ulcer disease and the H. pylori infection. What are the symptoms of ulcers? The most frequent symptom noted with ulcers is a gnawing, burning pain in the mid stomach area just below the rib cage. Its onset is usually gradual over weeks or months rather than an acute beginning. The pain typically occurs when the stomach is empty between meals and in early morning hours. It can last from minutes to hours and is relieved by eating or taking antacids. Less frequently occurring are symptoms such as nausea, vomiting, and loss of appetite. Bleeding from the ulcer may result in black, tar-like stools, vomiting of blood or even coughing up of blood.

Does Helicobacter pylori cause stomach cancer?
Helicobacter pylori, or H pylori as it is also known, is a type of bacteria that is found in the lining of the stomach. A lot of different types of bacteria enter the stomach when we eat or drink. Most of this bacteria is killed by the acid contents of the stomach, but H pylori is not. H pylori is a common bacterial infection and between 30-40% of people in Britain are infected, although the incidence is declining. H pylori can usually be successfully treated with antibiotics. H pylori can cause inflammation of the stomach lining (gastritis) which may over time develop into stomach (gastric) cancer. As a result, H pylori has been recognized as a carcinogen (a substance that causes cancer) and people who are infected with H pylori are thought to have 3-6 times the risk of developing stomach cancer than people who are not infected. If the H pylori is treated with antibiotics this often stops the development of cancer as well. The majority of people who are infected with H pylori will not develop stomach cancer and less than 3% of people actually do. Doctors have been looking in to why this happens but currently do not know why this is. It is thought that there may be some interaction with some of the other risk factors associated with the development of stomach cancer, such as smoking and poor diet.

Ulcer-causing bacteria found in surface water
June 1998
U.S. Water News Online ATLANTA, Ga. The bacterium blamed for most stomach ulcers may lurk undetected in surface water. Helicobacter pylori , the cause of chronic gastritis, peptic ulcer disease, and certain types of stomach cancer has been found in river, creek, and lake water in central Pennsylvania. Although H. pylori infects half the world's population, evidence for a primary source of infection previously has been unknown. Dr. Katherine Baker, Assistant Professor of Environmental Microbiology and John Hegarty, a graduate student at Penn State Harrisburg, found H. pylori in more than 75 percent of 36 tested surface water samples in Central Pennsylvania. This study is the first report of H. pylori in surface water in the United States, demonstrating a major reservoir for this organism outside the human body. The results of the research were delivered on in May at the 98th General Meeting of the American Society for Microbiology in Atlanta, Georgia. "Water looks to be a major factor in the transmission of the bacterium," Dr. Baker said, pointing out that the organism was found in both surface water and untreated groundwater from shallow wells where surface water contamination is likely to occur.

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

Research Interests
We are interested in how bacteria interact with their animal hosts in disease and in normal development. Our focus is Helicobacter pylori which colonizes the stomachs of over half the world's population. In most infected individuals H. pylori is a benign gastric resident, however in certain cases it becomes a serious pathogen and even carcinogen, causing gastritis, peptic ulcers, gastric adenocarcinoma, or mucosal-associated lymphoid tissue lymphoma. The disease outcome is determined by both host and bacterial genetic factors in a complex interplay, as each genome responds to and is regulated by the other. We would like to understand the molecular nature of the bacterial-host dialogue that determines disease outcome. Bacterial manipulation of host cells
We have examined the effect of H. pylori

Helicobacter Pylori
What is Helicobacter pylori (H. pylori)?
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?
It is believed that H. pylori's shape and characteristics cause the damage that leads to ulcers.
Because of their shape and the way they move, the bacteria can penetrate the stomach's protective mucous lining where they produce the enzyme urease, which generates substances that neutralize the stomach's acids. This weakens the stomach's protective mucus, makes the stomach cells more susceptible to the damaging effects of acid and pepsin, and leads to sores or ulcers in the stomach or duodenum (first part of the small intestine).
The bacteria can also attach to stomach cells, further weakening the stomach's defensive mechanisms and producing local inflammation. For reasons not completely understood, H. pylori can also stimulate the stomach to produce more acid.
