Summary
Circulating immune complexes (CIC) in children with dog allergy-induced asthma were measured before and during immunotherapy. CIC levels did not increase during treatment, but correlated with specific IgG antibodies during maintenance therapy.
Area of Science:
- Immunology
- Allergy Research
- Pediatric Asthma
Background:
- Dog allergy is a common cause of asthma in children.
- Immunotherapy aims to desensitize patients to allergens.
- Circulating immune complexes (CIC) are potential biomarkers in allergic diseases.
Purpose of the Study:
- To investigate CIC levels in children with dog allergy-induced asthma undergoing immunotherapy.
- To assess changes in CIC during different phases of immunotherapy (pretreatment, rush, maintenance).
- To explore the correlation between CIC and specific IgG antibodies.
Main Methods:
- Analysis of CIC in 35 dog-allergic asthmatic children receiving immunotherapy.
- Utilized KgB-ELISA, C1qB-ELISA, RFb-ELISA, and PIPA assays for CIC determination.
- Included placebo, untreated atopic, and non-atopic children as controls.
Main Results:
- Pre-treatment CIC levels were higher in dog-allergic children than atopic controls (P<0.05).
- CIC levels remained stable during conventional and rush immunotherapy phases.
- A significant correlation (P<0.01) was found between CIC and dog dander-specific IgG during maintenance therapy.
Conclusions:
- Immunotherapy for dog allergy-induced asthma does not appear to increase CIC levels.
- CIC levels may correlate with specific IgG antibody responses during long-term immunotherapy.
- Further research is needed to understand the role of CIC in immunotherapy outcomes.
