Mites are difficult to detect with the naked eye, and are more likely to be the invisible culprit of allergy.

After eating muffins made by her family, a young girl suddenly developed leprosy all over her body and developed a fatal anaphylactic shock. The investigation revealed that the pancake powder of the muffins had discolored and had deposits. Under the microscope, it was found that there were many storage mites and other Young people who have been plagued by dust mites for many years often have sensitive eyes and nose, which seriously affects the campus and daily life.


At present, there is no suitable substance to prevent the breeding of mites. The Faculty of Medicine of the Chinese University of Hong Kong has established a genomics basis for the diagnosis and intervention of "mite allergy" by studying the evolutionary history of mites, which is helpful for drug screening to find suitable compounds. As a tool for effective control of mites.


Household dust mites are the main allergens of about 40-60% of allergic people in Hong Kong

More than half of the Hong Kong population suffers from at least one allergic disease, among which house dust mites are the main cause of allergy among about 40-60% of the allergic people in Hong Kong.

Common reactions of mite allergy include nasal itching, sneezing, nasal congestion and severe coughing at night. If patients ingest food contaminated with mite, they will experience rapid breathing, throat swelling, dizziness, and even fatal anaphylactic shock.

Airless mites are composed of household dust mites, storage mites and parasitic mites (such as scabies mites). Among them, storage mites appear in improperly stored food powders, while dust mites attach to household mattresses and plush toys. Scabies can spread quickly in crowded environments.

17-year-old girl suffers fatal anaphylactic shock after eating Pancake containing storage mites

Leung Shi-yen, Assistant Professor of the Department of Pediatrics, Faculty of Medicine, CUHK shared that there was a 17-year-old girl who ate muffins made by her father in the morning. She had difficulty breathing, stuffy nose, and itchy eyes during the bus ride back to school. The whole body suffers from leprosy, and after seeking medical treatment in the emergency room, it is found that it is anaphylactic shock, which can affect the skin, respiratory tract, cardiovascular, nerve, intestinal tract, etc. If treatment is delayed, it may be fatal.

Okonomiyaki ready-mixed powder and milk powder may also have storage mites if they are not stored well

After investigation, it was found that the culprit was the muffin pancake powder that had been in the house for a period of time. The powder had discolored and sediment appeared. Many storage mites were found under the microscope, some of which were mite carcasses.

Liang Shiyan reminded that Japanese-style okonomiyaki ready-mixed powder, milk powder, etc. are not stored well, and there may also be storage mites, causing allergic reactions.

As for Adam, who is 18 years old this year, he has been plagued by eczema since he was a child. When he was in elementary school, he developed sensitive eyes and nose. His eyes are prone to redness and swelling, and he is afraid of light. Unable to go to school due to discomfort, follow up at least once a week, more difficult to participate in extracurricular activities, is one of the allergic patients affected by dust mites.

Scabies is a contagious skin disease caused by scabies mites in the epidermis of human skin.

CUHK: Storage Mites Can Cause Acute Allergy Even When Cooked or Killed

Xu Guorong, a professor at the School of Biomedical Sciences, Faculty of Medicine, CUHK, said that in recent years, many people like DIY, but when the raw materials are stored improperly, after opening the package, there is a chance that the storage mites will grow and multiply, so it is recommended to store them in a dry place (such as snow cabinet), do not expose to the air for a long time after opening, and do not store it for too long: "It's okay to cook, even if the storage mites are cooked and killed, their proteins will be sensitized, which can cause acute Min."

Ideal for drying quilts on the street or attracting dust mites in a dryer

On sunny days, some citizens choose to bring bed sheets and quilts to the street to bask in the sun. Liang Shiyan reminded that when dust blows, the newly cleaned quilts will be attached. , and then put it in the dryer to dry, and minimize the use of young children to hold fur dolls to avoid allergens.

There is currently no cure

In terms of treatment methods, she said that Adam relied on palliative drugs to reduce inflammation when he was young, and his allergies became more serious as he grew up. Therefore, after changing to a desensitization treatment for dust mites, he received subcutaneous injections during the three-year treatment period to improve. Allergies, but not completely cured.

She pointed out that if the public finds that the first-line treatment drugs (such as nasal steroids) are ineffective, the home environment has been thoroughly cleaned, the allergy is still seriously affecting their life, and it is confirmed that they are allergic to mites, they can go to the allergy department to check whether they are suitable for desensitization treatment. .

However, the course of treatment should be paid for at your own expense, costing several thousand yuan per month for two or three years, and the price is not cheap.

Regarding the increasing number of allergy cases in children under 14 in the past few decades, Xu Guorong explained that since the SARS in 2003, the public's requirements for environmental hygiene have increased, especially for children, but when children aged 0 to 3 develop their immune systems completely Substances that are avoided and only come into contact with after growing up will be regarded by the body as an "enemy" to attack. It can be seen that although infectious diseases are reduced in a clean environment, there is also the opportunity to increase the possibility of allergies. Just as the more diverse the types of food eaten between 0 and 3 years old The research indicates that the chance of food allergy will decrease when you grow up, which is an immune system problem.

CUHK Jiyan treats "mite allergy" by targeting unique genes of dust mites and harmless drugs to humans

In addition to high temperature and humidity control, there are still no suitable substances to prevent the breeding of mites.

The CUHK Faculty of Medicine conducted a comparative genomics analysis of airless mites using six high-quality genomes and found many abnormal horizontal gene transfer from soil bacteria.

These transfers introduce genes with important functions and enhance the mites' resilience, especially in detoxification and digestion.

Since humans do not have these gene transfers, they can be regarded as ideal drug targets for the control of airless mites. For these unique genes, suitable compounds can be found as tools to effectively control mites. It is hoped that in the future, a unique gene targeting dust mites will be developed. , Harmless to humans.

The research results have been published in the prestigious international evolutionary biology journal "Molecular Biology and Evolution".
