RESUMO
BACKGROUND: the purpose of this study was to investigate the presence of respiratory allergy in 30 Mexican patients bearing cystic fibrosis (CF). METHODS AND RESULTS: all patients completed a clinical history, had a physical examination, total serum IgE, nasal and blood eosinophils determinations and evaluation of skin prick tests for 36 allergens. In 26.6% of the patients included in the study was detected respiratory allergy diagnosed on clinical and laboratory analyses. Skin prick tests of 11 (36.6%) of the patients were positive to at least one allergen and Aspergillus fumigatus (A. fumigatus) was the most frequently observed allergen in 23% of the cases. CONCLUSIONS: we have demonstrated in this study that Mexican patients also present a coexistence of respiratory allergy in patients bearing CF.
