Allergic constitution

Xiangxiang was born in September 1997 and has been attending kindergarten for six months.
Due to space constraints at the school, all activities outside the classroom are held in the basement.
The home is located near a busy road with a lot of dust, and he frequently suffers from colds (already has an L card).
Recently, blood tests indicated a level 4 allergy to dust mites.
Both parents' blood tests showed no allergic predisposition.
They prefer not to use medication or injections for treatment.
The family has recently installed an air purifier.
Is the school environment contributing to this issue, and what improvement methods can be suggested? When should he undergo another blood test? Thank you for your response.

Hello: After blood tests, it has been confirmed that Xiangxiang has a dust mite allergy.
Dust mites are tiny arthropods that feed on human skin and are not easily visible to the naked eye.
They often hide in high-humidity areas of woolen fabrics.
Their waste and decomposed remains can irritate the human respiratory tract, leading to allergic reactions.
To address the dust mite issue, it is essential to reduce woolen items in the home (including carpets, curtains, stuffed animals, and wool balls) and use a dehumidifier to lower humidity levels, making it inhospitable for dust mites.
An air purifier without dehumidifying capabilities will not significantly help in reducing dust mites.
While outdoor dust can also irritate the respiratory tract, the particles are generally too large to be inhaled into the trachea, and wearing a mask can help reduce inhalation of these particles.
There are fewer woolen items in schools, but poor hygiene habits among children can lead to saliva exchange, making it a breeding ground for colds.
To prevent transmission, it is important to teach children good handwashing habits.
As for the allergic constitution, it will not change with medication or injections, so there is no need for further blood tests.
(Director Zhao is on leave due to personal matters.) Thank you for your letter.
Wishing you peace and health.
Sincerely, Dr.
Kang Danqi, Attending Physician, Pediatrics, Hsinchu Hospital, Department of Health.

More Info

Managing allergies in children, particularly dust mite sensitivity, can be a challenging yet manageable task. Dust mites are microscopic organisms that thrive in warm, humid environments, often found in bedding, upholstered furniture, and carpets. Given that your child, Xiangxiang, has been diagnosed with a high level of dust mite allergy, it is essential to understand the implications and explore effective management strategies.

Understanding Dust Mite Sensitivity
Dust mite allergies manifest when a child's immune system reacts to proteins found in dust mite waste and body fragments. Symptoms can include sneezing, runny or stuffy nose, itchy eyes, and even asthma-like symptoms such as wheezing and difficulty breathing. The fact that Xiangxiang has been frequently ill and has a high allergy level indicates that his environment may be contributing significantly to his symptoms.

Environmental Factors
The environment plays a crucial role in managing dust mite allergies. Since Xiangxiang's school is located in a basement with limited ventilation and potentially higher humidity, this could exacerbate his allergy symptoms. Additionally, living near a busy road can increase exposure to other allergens, such as pollen and vehicle exhaust, which may compound his respiratory issues.

Solutions and Management Strategies
1. Home Environment Adjustments:
- Air Purifiers: You mentioned that you have installed an air purifier at home. Ensure that it has a HEPA filter, which can effectively trap dust mites and other allergens. Regularly replace the filters as recommended by the manufacturer.

- Bedding: Use dust mite-proof covers on pillows and mattresses. Wash bedding weekly in hot water (at least 130°F or 54°C) to kill dust mites.

- Cleaning: Regularly vacuum carpets and upholstered furniture using a vacuum cleaner equipped with a HEPA filter. Consider removing carpets if possible, as they can harbor dust mites.

- Humidity Control: Keep indoor humidity levels below 50% using dehumidifiers if necessary, as dust mites thrive in humid conditions.

2. School Environment:
- Discuss with the school about potential changes to the classroom environment. If possible, advocate for better ventilation and cleaning practices to reduce dust accumulation.

- Encourage the school to use air purifiers in classrooms, especially if they are in a basement.

3. Avoidance Strategies:
- Limit exposure to known allergens. For example, if Xiangxiang has a reaction to certain materials or environments, try to minimize his exposure to those triggers.

- Educate him about his allergies so he can communicate his needs, especially in school settings.

4. Medical Management:
- While you mentioned a reluctance to use medications or injections, it is essential to consult with an allergist or pediatrician about potential treatments. Options may include antihistamines or nasal corticosteroids to manage symptoms effectively.

- Allergy shots (immunotherapy) may also be considered in the future if environmental management alone does not provide sufficient relief.

Follow-Up and Monitoring
Regarding follow-up blood tests, it is generally advisable to reassess allergy levels after a significant period of environmental management, typically every 6 to 12 months. This allows you to gauge whether the implemented strategies are effective in reducing Xiangxiang's sensitivity.

Conclusion
Managing dust mite allergies in children requires a comprehensive approach that includes environmental modifications, education, and possibly medical intervention. By taking proactive steps to reduce exposure and improve Xiangxiang's living and learning environments, you can help alleviate his symptoms and enhance his quality of life. Regular follow-ups with healthcare providers will ensure that his allergy management plan remains effective and responsive to his needs.
