Brief Summary
This study is a Study to Understand How to Better Match Allergy Shots to a Child's Unique Mite Allergy Profile
- 1.Why is this study being done? For many children, tiny house dust mites are a major cause of persistent allergies, leading to uncomfortable symptoms like a stuffy nose, sneezing, and even asthma. A common long-term treatment is allergy shots, also known as allergen immunotherapy (AIT). These shots work like a vaccine, slowly training the body's immune system to stop overreacting to mites. However, not every child responds to this treatment in the same way. The investigators now know that children can be allergic to different parts of the dust mite. While most treatments focus on the most common parts (called "major allergens"), some children are allergic to other, less common parts (called "intermediate or minor allergens").
- 2.Who is this study for? The investigators are looking for children and teenagers (ages 5 to 18) in China who have a confirmed dust mite allergy and are planning to start allergy shots.
- 3.What will happen during the study? This is an "observational" study, which means the investigators will simply observe and track the progress of children who are already receiving a standard, approved allergy shot treatment as part of their regular medical care. The investigators won't be testing a new drug.
- 4.What do the investigators hope to learn? The investigators have a main theory, or hypothesis: Children who are allergic to many different parts of the dust mite (including the minor ones) will show greater improvement from the allergy shots, compared to children who are only allergic to the most common parts.
- 5.Why is this study important? This is the first large-scale study of its kind in a real-world setting. The results could change how doctors diagnose and treat dust mite allergies in children. Instead of just knowing a child is allergic to mites, the investigators will be able to see the full picture of how they are allergic. This knowledge will help ensure that every child receives the treatment that gives them the best chance for long-term relief.

Outcome Measures
Primary Outcomes (1)
The Changes of CSMS
the change from baseline in Combined Symptom and Medication Scores (CSMS). CSMS includes a symptom score and a medication score. The minimum value for the symptom score is 0 and the maximum is 3. The minimum value for the medication score is 0 and the maximum is 3. The combined score is the sum of these two scores, with a higher score indicating more severe symptoms.
evaluated at months 3, 6, 12, 24, and 36
Secondary Outcomes (2)
serological markers
at years 1, 2, and 3
Visual Analog Scale (VAS) scores
evaluated at months 3, 6, 12, 24, and 36
Study Arms (2)
major allergens group
The group containing only major allergen components detected by Component-Resolved Diagnosis
intermediate/minor allergens group
The group containing intermediate/minor allergens with or without major components.
Eligibility Criteria
This study plans to recruit participants from multiple research centers across China between November 2025 and November 2028. The target population is children aged 5 to 18 years who have been confirmed as having dust mite allergy through allergen testing and are scheduled to receive subcutaneous specific immunotherapy with a dust mite dual-allergen preparation.
You may qualify if:
- (1) Age: 5 years ≤ age \< 18 years; (2) 1) Allergic rhinitis caused by Dermatophagoides pteronyssinus and/or Dermatophagoides farinae; 2) Or serum specific IgE ≥ 0.70 (kU/L) (for D. pteronyssinus and/or D. farinae); (3) Children meeting criteria (2) must undergo allergen component testing; (4) If accompanied by bronchial asthma, asthma must be diagnosed according to the Guidelines for the Diagnosis and Prevention of Childhood Bronchial Asthma (2025 edition) and the patient's asthma symptoms must be confirmed as well-controlled.
- (5) Receiving treatment with dual-mite (Dermatophagoides pteronyssinus and farinae) subcutaneous immunotherapy (SCIT).
You may not qualify if:
- (1) Participants and/or their parents/legal guardians are judged by the investigator to be unable to fully understand the study requirements, or to adhere to long-term treatment and identify adverse reactions (including but not limited to conditions such as cognitive impairment or mental illness); (2) Children with severe or uncontrolled asthma (FEV1 \< 70% of predicted value) or with irreversible airflow obstruction; (3) Children using beta-blockers or angiotensin-converting enzyme inhibitors (ACEI); (4) Children with severe autoimmune diseases or immunodeficiencies, including AIDS, inflammatory bowel disease, etc., as well as those currently using immunosuppressants; (5) Children with severe cardiovascular diseases or malignant tumors; (6) Children with incomplete clinical data.
