Learn About H. Pylori Bacteria

What is H.P bacterial infection?
H.P (Helicobacter pylori) bacteria are often found in the stomach, sinuses, intestinal tract, oral cavity, etc. is the main cause of peptic ulcer; Acute, chronic gastritis and gastric cancer.
H

.P bacteria can be transmitted through eating, drinking, digestive juices, or unhygienic fruits and vegetables, etc. According to statistics, the percentage of Vietnamese infected with HP bacteria is up to 70%. Therefore, regular health checkups, especially HP tests, to diagnose and treat H P bacteria play a very important role Help protect stomach health and also prevent complications.
Who should get tested for H.



. Pylory?
Not everyone with stomach problems needs to have an HP test, because this bacterium can coexist "peace" in the stomach and sometimes it also eliminates the pathogens of the gastrointestinal tract. On the other hand, not all cases of stomach illness are caused by HP bacteria but there are many other causes. Therefore, in the following cases, a new physician should be tested for HP bacteria:
Having peptic ulcer or a history of peptic ulcer, each treatment of gastric cancer through endoscopy, lymphoma associated with gastrointestinal mucosa;
Must take aspirin for a long time;
Have indigestion, heartburn, persistent abdominal pain ..;
People used to have stomach cancer
Methods for testing H. pylory of the stomach
The following are some commonly used testing methods:
Stomachoscopy method
Gastroscopy is a fairly safe and effective test method, accurately diagnosing the HP infection in the stomach, assessing the extent and location of lesions, thereby making a diagnosis of the condition. of the disease and have the most appropriate treatment regimen.
With this method, the doctor uses a small endoscope with a light source (light bulb) and camera inserted into the body through the mouth or the nose.



. Then, take the biopsy needle around the injured area in the stomach and place the specimen in a small test tube, soak the biopsy piece in a mixture of solutions and measure the results after 5-10 minutes. If the solution changes to a pink color, there is HP bacteria in the stomach (positive HP stomach test).
Ure breath test
The patient will breathe into an HP bacterial testing device. There are currently 2 types:
Use the ball: the patient blows directly into a balloon-like device
Using the card: the patient blows into the device like an ATM card.
The breath will then be analyzed and evaluated by this device. If a positive result (+) indicates an HP infection, and a negative (-) result, there is no HP infection.
HP testing by Urea breath test results are very fast with high accuracy, applicable to all subjects, including children. Suitable for patients who have already been treated for HP and need to evaluate the effectiveness of the treatment
Stool test
H.P bacteria survive in the stool if there is H.



.P bacteria in the stomach. Currently, finding HP in stool has many methods, however there are 2 methods that can be used:
Quick test for H.P antigen by immunochromatographic method.
Automated immunological method: fluorescence or fluorescence immunity ...
HP assay by stool testing method is easy to perform, giving fast results with very high accuracy.
Blood tests detect HP bacteria
When a patient has an HP infection, the body produces antibodies to HP, which can be detected in the blood by testing for antibodies in the blood. A blood test to detect HP bacteria is a common test, present in most clinics.




But this is not the preferred test done because of the high likelihood of false positives. The reason is that HP bacteria can exist in many areas and also make a positive blood test, such as the oral cavity, intestinal tract but absolutely no disease. Another reason is that although the HP bacteria in the stomach were completely eradicated, the patient cured completely, but anti-HP antibodies remained in the blood for months, even up to a few years.
