Insights
Pollen sensitization is common in childhood asthma, with gramineae pollens being the most frequent allergen. This study highlights key epidemiological and clinical features of allergic asthma in children.
Area of Science:
- Pediatric Allergy and Immunology
- Environmental Health
- Respiratory Medicine
Context:
- Childhood asthma prevalence is significant globally.
- Allergen sensitization, particularly to pollens, is a major contributing factor.
- Understanding specific pollen allergies is crucial for effective asthma management in children.
Purpose:
- To investigate the prevalence and characteristics of pollen sensitization in asthmatic children.
- To identify common pollen allergens and their association with asthma symptoms.
- To assess the epidemiological and clinical profile of children with pollen-allergic asthma.
Summary:
- This retrospective study analyzed 86 asthmatic children (out of 638) sensitized to pollen.
- The mean age of participants was 4 years, with first respiratory symptoms appearing around 1.5 years.
- Gramineae pollen sensitization was most common, followed by olive, cypress, and herbaceous pollens. 77% experienced asthmatic attacks, and 55% had associated rhinitis or conjunctivitis.
Impact:
- Provides insights into the role of pollen allergy in pediatric asthma.
- Informs targeted allergen avoidance and immunotherapy strategies.
- Contributes to the epidemiological data on allergic respiratory diseases in children.
Abstract:
This retrospective study was designed to determine the place of pollen sensibilization in asthmatic child and to assess its epidemiological and clinical characteristics. 86 from 638 asthmatic child were allergic to pollen and included in the study. The mean age was 4 years (extremes : 1-12 years). The mean age of first respiratory manifestations was 1 and half years. The male/female ratio was 1.46. Asthmatic attacks was noted in 77% of cases, chronic cough was the only allergic manifestation in 16% of cases. Associated rhinitis or conjunctivitis were found in 55% of cases, atopic dermatitis was found in 4 patients (4.6% of cases). Atopic asthma was per annual in 78% of cases. Pollinic asthma was diagnosed in 51 child. Other sensibilization were found in 60% of cases. 26 child (32%) were allergic to pollen only and 18 child to sample pollen. The gramineae pollen sensibilization is the most common allergy, followed by olive tree and cypress tree and herbaceous pollens.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
