This study tracked specific immunoglobulin E (sIgE) responses to common ragweed and mugwort pollen allergens over six years. Mugwort pollen showed stronger allergenicity, with higher sensitization rates observed in males and younger individuals, indicating potential cross-reactivity.
Area of Science:
- Allergy and Immunology
- Environmental Health
- Epidemiology
Background:
- Common ragweed and mugwort are prevalent aeroallergens contributing to allergic respiratory diseases.
- Understanding sensitization trends to these allergens is crucial for public health management.
- Longitudinal data on specific immunoglobulin E (sIgE) responses provides insights into allergenicity and population susceptibility.
Purpose of the Study:
- To analyze sensitization trends to common ragweed and mugwort pollen allergens over a six-year period.
- To identify demographic factors influencing sensitization rates, including age and gender.
- To compare the allergenicity and cross-reactivity patterns of common ragweed and mugwort.
Main Methods:
- Retrospective analysis of 2798 patient records with common ragweed and mugwort pollen-sIgE testing (2020-2025).
- Exploration of sensitization characteristics across different time periods, age groups, and genders.
- Comparative analysis of sensitization profiles and IgE detection levels.
Main Results:
- Positive rates for both allergens decreased from 2020-2024, with a rebound in 2025.
- The 6-15 years age group showed the highest positive rates, decreasing with age.
- Males exhibited significantly higher sensitization rates than females for both allergens.
Conclusions:
- A rebound in common ragweed and mugwort pollen-sIgE positive rates was observed in 2025.
- Sensitization rates decreased with age and were higher in males.
- Mugwort pollen demonstrated stronger allergenicity, with high consistency and cross-reactivity observed between the two allergens.
