Summary
Cockroach allergy is common in Beijing patients with allergic rhinitis and allergic asthma, with over 24% testing positive. Most patients show sensitization to multiple allergens, and adults have a higher sensitization rate than children.
Area of Science:
- Allergology
- Immunology
- Environmental Health
Context:
- Allergic rhinitis (AR) and allergic asthma are significant public health concerns.
- Cockroach sensitization is a recognized trigger for allergic respiratory diseases.
- Understanding regional sensitization patterns is crucial for effective allergy management.
Purpose:
- To investigate the prevalence and characteristics of cockroach sensitization in patients with AR and/or allergic asthma in Beijing.
- To identify demographic and clinical factors associated with cockroach sensitization.
- To inform prevention and treatment strategies for cockroach-sensitized individuals.
Summary:
- A retrospective analysis of 9,915 patients in Beijing revealed a 24.79% overall cockroach sensitization rate via skin prick testing (SPT).
- The highest sensitization rate (31.65%) was observed in the 15-19 year age group, with rates generally increasing with age up to 20.
- Over 90% of cockroach-sensitized patients also reacted to other indoor allergens, with Der f and Der p being most common. Adult patients exhibited higher sensitization rates than juveniles, particularly in the AR group (P<0.001).
Impact:
- This study highlights the significant burden of cockroach allergy in Beijing's allergic respiratory disease population.
- Findings underscore the importance of considering cockroach as a major allergen in this region.
- The high rate of multiple allergen sensitization emphasizes the need for comprehensive allergen avoidance and management plans.
