H.Pylori - Cholesterol Test Descriptions

H.Pylori (Stomach Ulcer and / or Cancer)
Infection with Helicobacter pylori, a type of bacteria, is a major cause of stomach ulcers and ulcers of the duodenum. It may also increase the risk of developing stomach cancer. In some people, H. pylori bacteria grow in the lining of the stomach and duodenum and may cause inflammation. This inflammation can increase a person's risk of developing an ulcer. However, not all people infected with H. pylori develop ulcers. H. pylori can often be transmitted to humans from pets.

What is H.Pylori?
Helicobacter Pylori (H. Pylori) is a spiral shaped bacterium, found in the gastric mucus layer or adherent to the epithelial lining of the stomach. H. Pylori causes more than 90% of duodenal ulcers and more than 80% of gastric ulcers. Before 1982, when this bacterium was discovered, spicy food, acid, stress, and lifestyle were considered the major causes of ulcers. The majority of patients were given long-term maintenance doses of acid-reducing medications, without a chance for permanent cure. Since we now know that most ulcers are caused by H. Pylori, appropriate antibiotic regimens can successfully eradicate the infection in most patients, with complete resolution of mucosal inflammation and a minimal chance for recurrence of ulcers.
How common is H. Pylori infection?
Approximately two-thirds of the world's population is infected with H. Pylori. In the United States, H. Pylori is more prevalent among older adults, African Americans, Hispanics, and lower socioeconomic groups.

What illnesses does H. Pylori cause?
Most persons who are infected with H. Pylori never suffer any symptoms related to the infection; however, H. Pylori causes chronic active, chronic persistent, and atrophic gastritis in adults and children. Infection with H. Pylori also causes duodenal and gastric ulcers. Infected persons have a 2 to 6 fold increased risk of developing gastric cancer and mucosal-associated-lymphoid-type (MALT) lymphoma compared with their uninfected counterparts.

What are the symptoms of ulcers?
Approximately 25 million Americans suffer from peptic ulcer disease. Each year there are 500,000 to 850,000 new cases of peptic ulcer disease and more than one million ulcer-related hospitalizations. The most common ulcer symptom is gnawing or burning pain in the epigastrium. This pain typically occurs when the stomach is empty, between meals and in the early morning hours, but can also occur at other times. It may last from minutes to hours and may be relieved by eating or taking antacids. Less common ulcer symptoms include nausea, vomiting, and loss of appetite. Bleeding can also occur; prolonged bleeding may cause anemia leading to weakness and fatigue. If bleeding is heavy, hematemesis, hematochezia, or melena may occur.

Who should be tested and treated for H. Pylori?
Person with active gastric or duodenal ulcers or documented history of ulcers should be tested for H. Pylori, and if found to be infected, they should be treated.

How is H. Pylori infection diagnosed?
Several methods may be used to diagnose H. Pylori infection:
Serological (blood) tests that measure specific H. Pylori lgG antibodies can determine if a person has been infected.
The biopsy urease tests is a colorimetric test based on the ability of H. Pylori to produce urease; it provides rapid testing at the time of biopsy.
Histological identification of organisms is considered the gold standard of diagnostic tests.
Culture of biopsy specimens for H. Pylori requires an experienced laboratory and is necessary when antimicrobial susceptibility testing is desired.

What are the treatment regimens used for H. Pylori eradication?
Most ulcers are caused by an H. Pylori infection and can be cured in about 2 weeks with antibiotics. Antibiotic resistance and patient noncompliance are the two major reasons for treatment failure.
