Abstract

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.
