Helicobacter pylori (HP) has been clearly listed as human carcinogens. Many people use the screening of Helicobacter pylori as the basic medical examination items for the basics. You can panic when you see the inspection results "HP positive": Do I have to get cancer? Intersection

Dr. Dr. Dai Qian, a member of the Sichuan Health Management Association and the Health Examination Center of the Huaxi Hospital of Sichuan University, said that in fact, more than half of the Chinese infected with H. pylori (HP). -20%of people will have digestive ulcers, 5%-10%of people will have indigestion, 1%of talents will have gastric malignant tumors, and most infected people are not asymptomatic.

Why is someone infected with pylori without symptoms?

Dr. Dai Qian introduced that as the most "successful" pathogen in the history of bacterial development, Helicobacter pylori has successfully become bacteria that can be resident in the stomach with strong acid resistance.

"From the perspective of the serum classification type of Helicobacter pylori, it can be mainly divided into: type I, VACA and CAGA protein or antibodies at the same time; type II, VACA and CAGA protein or antibodies are negative; intermediate type, VACA or CAGA Any positive protein or antibody. "Dr. Dai Qian said that VACA and CAGA are two important toxic factors for H. pylori.

In simple terms, type I HP, also known as poisonous HP, can cause extensive inflammation and damage to the gastric mucosa, and then promote the development of severe gastric diseases such as ulcers. The II HP is called non -toxic force HP, which is generally manifested as mild digestion, and the toxic force of the intermediate HP is between type I and II. This is why pylori is also infected with pylori, and some people have severe stomach diseases, while others have no symptoms.

What are the detection methods of pylori?

There are many ways to detect Helicobacter pylori infection, including gastroscopy biopsy+fast urea -enzyme test, biopsy+bacterial culture, 13 carbon/14 -based gas exhalation test, feces antigen detection, and serum antibody testing.

"During the physical examination, the most commonly used detection method is 13 carbon or 14 carrons exhalation tests. This test can determine whether you have infected with H. pylori, but it cannot recognize type Ⅰ and Ⅱ poisoning strains. At present The serum science type of HP HP HP, only a few milliliters of venous blood can be taken to complete the relevant test. "

Do you want to eradicate the pylori infection?

Dr. Dai Qian introduced that the clinical guidelines did not mention its typing problem in the elimination indication of Helicobacter pylori. The severity of gastric mucosal disease does not only depend on the strength of the poisoning of Pymiocata, but also affected by the environment and host factors. "So, the result of a typing detection alone does not determine whether it needs to be eradicated. It also needs to be combined with its own basic situation, family history, and clinical manifestations. If necessary, it is necessary to combine the results of gastroscopy. Yes, the detection of Helicobacteriophyll typing provides multiple references for the formulation of clinical decision -making. For healthy people, carried out type testing can be more accurate to perform early gastric cancer early screening. "
