[Prevalence of sensitization to fungi in patients with respiratory allergy].

BACKGROUND

As part of the etiology of respiratory allergy we have genetics, prenatal factors and sensitivity to various airborne allergens, between these fungi are found. Relationship has been found between sensitization to fungal in skin tests and allergy pathogenesis and aggravation. There is a few literature in Mexico and in the north of the country it is lacking regarding this problem.

OBJECTIVE

Assess the prevalence of sensitization to fungi in patients with respiratory allergy in skin tests to airborne allergens; determine the most prevalent fungus and prevalence of sensitization to each species of fungus per year, to assess the prevalence of sensitization to fungi by years.

MATERIAL AND METHOD: Cross-sectional, observational and descriptive study conducted from 1 January 2010 to 31 December 2014 in patients treated at the Regional Center of Allergy and Clinical Immunology (Monterrey, Mexico) where we reviewed a database with patients whom performed skin tests, sensitization to 6 species of fungi were evaluated. We performed tables of data capture and statistical analysis.

RESULTS

4880 patients had respiratory allergy, a 17.1% prevalence of sensitization to fungal skin tests was determined. The fungus specie most prevalent was Alternaria alternata with 5.5%. The year range with the highest prevalence of sensitization was 0-10 years with a 6.7.

CONCLUSIONS

The prevalence of fungi sensitization was higher than the global prevalence found, but lower than the prevalence found in other researches in Mexico.
