Allergological study of pollen of mango (Magnifera indica) and cross reactivity with pollen of piru (Schinus molle)

With immediate skin test, we studied hypersensitivity to pollen of mango (Magnifera indica), and its probability cross-sensitivity to pollen of pirú (Schinus molle), from anacardaceae class. We have made one extract of Magnifera indica, with 0.485 mg per 100, of protein nitrogen. With this extract w...

Summary:With immediate skin test, we studied hypersensitivity to pollen of mango (Magnifera indica), and its probability cross-sensitivity to pollen of pirú (Schinus molle), from anacardaceae class. We have made one extract of Magnifera indica, with 0.485 mg per 100, of protein nitrogen. With this extract we carry out skin test on non-atopic subjects and atopic subjects with bronchial asthma and or allergy rhinitis and common stock of aerealergen. (Freeman stock). We studied seventy-one subjects, both sexes, from 14 to 40 years old. The prevalence of cutaneous sensitive to mango (Magnifera indica) were 66%, and sensitivity from Schinus molle were 31%. Those with sensitivity Schinus molle, were sensitivity from Magnifera, too. Statistical analyisis of correlation, with McNemar Test was p 0.001 under the conditions of the study we conclude that there are hypersensitivity to pollen of Magnifera, and there are cross-reactivity with Schinus molle. Therefore mangifera should be included within the stock of skin test in the areas were this anacardaceae is present.
