The infection rate of this bacteria is 50%, and you must know five transmission routes →
Helicobacter pylori is a common bacterium, which is mainly parasitic in human stomach and is considered to be one of the main causes of gastritis, gastric ulcer and duodenal ulcer. It is closely related to gastric cancer, gastric mucosa-associated lymphoid tissue lymphoma and other diseases.70% of gastric cancer is related to Helicobacter pylori., listed by the World Health Organization asClass 1 biological carcinogen.
If one person is infected, the whole family should be treated.
In June 2023, the White Paper "Prevention and Control of Helicobacter pylori Infection in China" issued by the Institute of Infectious Diseases Prevention and Control of China CDC pointed out that the infection rate of Helicobacter pylori among Chinese residents was nearly 50%. Many people in the family have detected Helicobacter pylori, and other family members are also infected.
In 2023, an epidemiological survey of Helicobacter pylori infection in 29 provinces showed that the overall family infection rate in China was 71.2%, which was significantly higher than the individual infection rate of 40.6%.
This is because Helicobacter pylori mainly exists in saliva, dental plaque, stomach and feces, and there are three main transmission routes:Word-of-mouth transmission, dung-mouth transmission, and common appliance transmission..
When a person is found to be positive for Helicobacter pylori, his family may be the first to be affected.
Helicobacter pylori can be detected in saliva, feces and vomit of infected people. Used tableware, dental equipment, toilets, etc., as well as contaminated food and water, may become the source of infection.
Helicobacter pylori is associated with many diseases.
one
Infection with helicobacter pylori
The risk of intestinal cancer is greatly increased.
Studies have confirmed that Helicobacter pylori, which can only survive in the stomach, also has a strong causal relationship with the occurrence of colorectal cancer.
2
May increase the risk of throat cancer
A meta-analysis of 11 studies showed that the infection rate of Helicobacter pylori in patients with throat cancer increased significantly. This is related to the toxins produced by Helicobacter pylori and toxic enzymes.
three
It not only causes cancer, but also harms the brain.
Recently, a study showed that Helicobacter pylori, which causes cancer, can also harm the brain. Compared with people who are not infected with Helicobacter pylori, people infected with Helicobacter pylori have an increased risk of Alzheimer’s disease by 11%, with the highest risk of infection from 7.3 to 10.8 years, and the highest risk of Alzheimer’s disease by 24%.
Do 5 points to prevent Helicobacter pylori infection
Helicobacter pylori infection is closely related to our daily living habits.Helicobacter pylori is mainly transmitted by mouth, so prevention should achieve these good habits.：
one
Choose a separate meal system at dinner.
Or use male chopsticks to avoid cross infection.
Oral transmission is the main route of Helicobacter pylori transmission from person to person.
2
Disinfect tableware regularly.
After washing the tableware at home, put it in the disinfection cabinet, boil it for disinfection or steam disinfection.
three
Don’t feed your child mouth to mouth.
By chewing food, putting a pacifier or spoon in your mouth to test the temperature, parents will spread the pathogenic bacteria in your mouth to your children.
four
Be sure to wash your hands before and after meals
Fecal transmission is also an important way of Helicobacter pylori transmission.
five
Avoid drinking raw water and eating raw food.
The weather is getting hotter, and some people often eat cold food or drink raw water. If food contains microorganisms and is not fully sterilized, it may also lead to Helicobacter pylori infection.
All four types of people should check for Helicobacter pylori.
People with risk factors include:
Peptic ulcer (whether active or not and whether there is a history of complications);
Gastric mucosa-associated lymphoid tissue lymphoma;
Patients with early gastric cancer underwent endoscopic submucosal dissection or subtotal gastrectomy;
Have a family history of stomach trouble;
Plan to take long-term non-steroidal anti-inflammatory drugs (including low-dose aspirin);
Helicobacter pylori gastritis;
Gastric hyperplastic polyp;
Helicobacter pylori-related dyspepsia;
Long-term use of proton pump inhibitors;
Primary immune thrombocytopenia;
Unexplained iron deficiency anemia;
Helicobacter pylori infection was confirmed (there was no countervailing factor for eradication treatment).
The detection methods of Helicobacter pylori includeNon-invasive and invasiveTwo kinds.
It is necessary to stop using acid inhibitors for at least 2 weeks and bismuth and antibiotics for at least 4 weeks before detection, otherwise the false negative rate will increase, that is to say, even if there is Helicobacter pylori infection, it may not be detected.
Non-invasive means collecting gas, stool and blood samples, usually including urea breath test, monoclonal stool antigen test and serological test.
Invasive methods are based on mucosal biopsy under gastroscope, usually including rapid urease test, pathological staining of gastric mucosa, Helicobacter pylori culture and polymerase chain reaction.
Find out whether Helicobacter pylori should be eradicated?
After being infected with Helicobacter pylori, patients may have symptoms such as heartburn, halitosis, burping, stomachache, nausea and vomiting, but only a small number of people will have symptoms.
The eradication of helicobacter pylori should be adhered to"Individualized assessment and treatment" principle. After the doctor makes a clear diagnosis and the patient has corresponding disease manifestations, it needs to be given appropriate treatment; If the patient is asymptomatic, he has reservations about eradication treatment.
If the infected person has peptic ulcer, Helicobacter pylori gastritis, gastric hyperplastic polyp, Helicobacter pylori-related dyspepsia, unexplained iron deficiency anemia, immune thrombocytopenia or family history of gastric cancer, it needs radical treatment.
