Cross sensitivity is a problem that materializes itself medically with the organization of two or more allergies, specified” go across allergic reactions – explains Danilo Raffaele Villalta, specialist Aaiito –  when antibodies directed to a particular irritant recognize similar allergenic particles existing in another allergenic source.

Cross responses take place

In cross responses also the courses of exposure of the irritant can be different: go across food allergy  allergies between plant pollen (inhaled irritants) and food (irritants ingested) or between latex (skin direct exposure) as well as some foods (digestive system direct exposure) are common “. “In grownups, approximately 80% of all instances of food allergic reaction – clarifies Aaiito – are preceded by sensitization to breathing allergens.

cross-responses-take-placeFor example, several foods consist of healthy protein molecules similar to those discovered food allergy  in some pollen. Actually, it is recognized that the major allergen of birch, which is a molecule of the defense system of plants, is likewise present in fruit, especially that of the

Rosaceae family (apples, pears, peaches, apricots, cherries, plums, and so on). , on the various other hand, there are particles similar to those had in termites so there may be topics with allergy to termites (allergic reaction from inhalants) as well as allergy to shellfish (from ingestion) “.

Generally those who are allergic to crustaceans are not allergic to a solitary shellfish particularly, but can be adverse the entire shellfish family as well as in many cases (concerning 50%) even to molluscs, mussels, cuttlefish “. ” – continues Aaiito

– differ substantially in various geographical areas as well as this is because of the kind of allergen to which the population is mainly sensitized. As an example in North Italy the cross reaction between birch as well as plant pollen is frequent, while in the South this is uncommon due to the limited existence of Betulaceae pollen, yet key sensitization to fruit linked to a molecule called

The cross responses

Lipid Transfer Protein (LTP) is regular, which is resistant to stomach juices as well as heat and also is responsible for extra severe signs and symptoms than in pollen/ fruit responses, which are normally limited to oral signs (dental sensitive syndrome).

To name a few things, in the latter instance the food can be consumed if prepared, while in food allergy  the case of sensitization to LTP it is not. Irritation, swelling and sores are the most common signs. , swelling and the look of sores on the dental mucosa but can additionally appear colds, skin, conjunctivitis and also asthma responses such as hives.

No to anti-allergy diet regimens on the web.

In most cases

Not all people allergic to plant pollen always have a cross-allergy to food as well as not all foods that contain molecules homologous to those of plant pollen cause signs. For these reasons it is essential that just the professional shows, situation by instance, if/ as well as which diet regimen to follow, additionally in order to restrict the threat of dietary inequalities.

in-most-casesIndividuals with this problem, consequently, must prevent adhering to diet regimens food allergy  showed in cross-reaction tables located on the net, since they are generic tables that do not mirror what takes place in the single individual “. “In instance of start of signs – recommends Antonino Musarra, Head Of State Aaiito
