Objectives:
To demonstrate cutaneous reactivity and the participation of Prosopis pollen in patients with allergic diseases who attend the Allergy and Clinical Immunology Service of the General Hospital of Mexico, in Mexico City.
Methods:
A retrospective and cross-sectional study was carried out by analyzing clinical records that had a complete medical history of patients between the ages of 3 and 79 years, with diagnoses of allergic rhinitis, asthma, and rhinoconjunctivitis.
Results:
1285 patients were studied; the frequency of positive skin reactivity for Prosopis was 27.78 %; 82.97 % had a diagnosis of allergic rhinitis, 4.39 % had a diagnosis of asthma, and 12.64 % had a diagnosis of rhinoconjunctivitis.
Conclusions:
Prosopis pollen plays an important role in diseases of allergic etiology. It is important to consider the antigenic combination with other families such as Chenopodiaceae.
Insights
Prosopis pollen is a significant allergen in Mexico City, triggering allergic diseases like allergic rhinitis. This study highlights the need to consider Prosopis in allergy testing and management.
Area of Science:
- Allergy and Clinical Immunology
- Environmental Allergens
- Public Health
Background:
- Allergic diseases are prevalent in Mexico City.
- Prosopis pollen is a common environmental allergen.
- Understanding local allergenicity is crucial for effective treatment.
Purpose of the Study:
- To assess cutaneous reactivity to Prosopis pollen.
- To determine the role of Prosopis pollen in allergic diseases.
- To identify allergic patients attending a specific clinic in Mexico City.
Main Methods:
- Retrospective and cross-sectional study design.
- Analysis of clinical records (n=1285) aged 3-79 years.
- Inclusion of patients diagnosed with allergic rhinitis, asthma, and rhinoconjunctivitis.
Main Results:
- Positive skin reactivity to Prosopis pollen observed in 27.78% of patients.
- High prevalence of allergic rhinitis (82.97%) among studied patients.
- Significant percentages diagnosed with asthma (4.39%) and rhinoconjunctivitis (12.64%).
Conclusions:
- Prosopis pollen is a key factor in allergic diseases.
- Antigenic interactions with other pollen families (e.g., Chenopodiaceae) should be considered.
- Clinical immunology services should routinely test for Prosopis sensitivity.

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.
