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.

Most people who are infected with H. pylori do not have any symptoms and will never develop illness as a result of the infection. Some people, however, develop ulcers in the stomach (gastric ulcers) or in the duodenum (duodenal ulcers) which is part of the small intestine that links the stomach to the large intestine.

It lives on the gastric epithelium under the mucus layer of the stomach and duodenum. The bacterium is thought to damage this mucus layer, which is the stomach and duodenum's natural protection from gastric acids. Local inflammation caused by the bacterial infection and exposure to these acids can damage the lining of the stomach and duodenum, eventually leading to ulceration and possibly gastric cancer.

HELICOBACTER The Helicobacter genus features Gram-negative, micraerophilic organisms that are very similar to organisms of the Campylobacter genus. Both species are motile, catalase-positive, and have curved cell bodies. When you think of Helicobacter , the first thing that should come to your mind is stomach ulcers. That is because this organism is the leading cause of peptic ulcers and chronic gastritis in America. The mechanisms for pathogenesis are not well understood at this time, but the circumstantial evidence points to Helicobacter pylori as the causative agent. Infected patients can be treated with an antacid as well as tetracycline to treat the ulcers and inhibit the growth of the organism. The microaerophilic nature of Helicobacter means that it requires a low oxygen concentration and a relatively high carbon dioxide concentration. Sufficient colony growth can be seen in three days when the organism is plated onto Brucella -sheep blood agar and placed in a microaerophilic environment. A Gram-stain will reaveal weakly stained rod with a unique curvature. Helicobacter pylori is also strongly urease-positive, which may help in identification.

Helicobacter pylori infection The importance of eradication in patients with gastric disease Anthony F. Bonagura, MD; Marta A. Dabezies, MD VOL 100 / NO 5 / NOVEMBER 1996 / POSTGRADUATE MEDICINE If your browser does not support tables click here. Third of four articles on peptic acid disease Preview : Few areas of practice have been so quickly and thoroughly revolutionized by a single finding as has management of peptic ulcer disease by the 1982 discovery that Helicobacter pylori infection and antral gastritis are strongly related. Empirical therapy for the infection is not recommended; the authors compare several methods of establishing the diagnosis before starting therapy. They also discuss currently used combinations of drugs and who should receive them. Beliefs concerning the cause and treatment of peptic ulcer disease have undergone numerous changes over the past 75 years. In the early part of this century, the disease was thought to be related to stress and dietary factors, so treatment consisted of bed rest and a bland diet. Later came an understanding of the injurious effects of gastric acid, and treatment focused on neutralizing the acidic environment of the stomach with antacids and antisecretory agents. Although the introduction of histamine2 (H2) receptor antagonists revolutionized treatment of peptic ulcer disease, disturbingly high recurrence rates forced many patients to continue long-term acid-suppression therapy. Recent development of proton pump inhibitors added a more effective therapeutic option but did not solve the problem of recurrent disease. Finally, the realization that peptic ulcer disease is usually the result of

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

Monograph Home Introduction Historical Perspectives The Bacteria ... Evaluation WHO SHOULD BE TESTED FOR H. PYLORI? Over the past several years, a number of consensus panels in the US and internationally have developed guidelines to assist clinicians in making decisions regarding how and when to test or treat for H. pylori infection. The continued evolution of knowledge regarding the natural history of the infection, recurrence rates, resistance rates, and clinical sequelae of eradication will undoubtedly modify these guidelines over time. One important generalization can be made, however: If the clinician plans to test the patient, under any circumstance, they should have already decided to treat if testing is positive. Peptic Ulcer Disease. It is universally accepted that patients with confirmed active duodenal or gastric ulcers should be tested for H. pylori , either at the time of endoscopic discovery of the ulcer or upon discovering the ulcer by other means (upper GI barium series). In addition, those patients with previously documented gastric or duodenal ulcer who had not been previously tested should probably be tested. Empiric treatment without testing in these patients is an option but should be weighed against the relatively small risk and cost of administering antibiotics and antisecretory drugs. 90% of duodenal ulcers and 70% of gastric ulcers are associated with H. pylori

Many peptic ulcers and some types of gastritis are caused by H. pylori infection, although most humans who are infected will never develop symptoms. This bacterium lives in the human stomach exclusively and is the only known organism that can thrive in that highly acidic environment. It is helix -shaped (hence the name helicobacter) and can literally screw itself into the stomach lining to colonize.
