Abstract
- Purpose
It is crucial to identify the causative allergen of respiratory allergic disease. Air pollution and climate change affect the allergen concentration as well as the sensitization rate. This study aims to analyze the inhalant allergen sensitization in patients with respiratory allergic disease in Busan and Gyeongsangnam-do province.
Methods
We retrospectively analyzed skin prick test results from patients who visited an allergy clinic at a university hospital in Busan and Gyeongsangnam-do in 2011 and 2016. Sensitivity to inhalant allergens was identified and analyzed by year and region. The pollen allergen concentration in Busan was also analyzed.
Results
The total numbers of participants were 697 in 2011 and 1,644 in 2016. The mite sensitization rate was the highest at approximately 36%, and tree pollen sensitization rate showed 10%–15%. However, the sensitization of most tree pollen and Japanese hop significantly decreased in 2016. In 2011, the mite sensitization rate of patients in the Western Gyeongsangnam-do region was remarkably low at 26%–28%, but this difference disappeared in 2016. The concentration of pollen allergens in Busan showed a tendency to decrease.
Conclusion
This study confirmed the longitudinal change in the sensitization rate of major inhalant allergens in patients with respiratory allergy in Busan and Gyeongsangnam-do province, as well as a significant decrease in tree pollen antigen. Based on our results, this information can be used as a basis for future patient management, and further research will be made possible by establishing a research network.
