It is called an allergy to food when in predisposed persons (atópicos) there forms an antibody (IgE) that joins proteins of some food and as a result there takes place a liberation of histamine and others mediating from the mastocitos of the skin and mucous membranes or of the basófilos of the blood that cause an allergic reaction. The allergy to food can affect 8 % of the children and 2 % of the adults. The substances capable of provoking an allergic reaction are known as substances alergénicas or, simply, alérgenos. The parts proteícas of the food are usually the causers of the allergic reactions, there are called they to these proteins allergens. Some allergens are thermosetting and for it they give allergic pictures with or without cooking (fish, seafood, meats, etc.) but others it are not and on having cooked them, they lose his aptitude to react (fruits pomáceas). The most common food alérgenos are the proteins of the milk of cow, the eggs, the peanuts, the fish, the seafood and the nuts. All the food comes from some plant or animal, and gathers together in families depending on his origin. The peanuts gather together with the vegetables (chick-pea, lentil, string beans) while the asparagus, the garlic and the onion are Liliáceas. It is very frequent that if a person is allergic to a food of a family is allergic to all the breaths related in the same one, but not always. The symptoms of a food allergy can be only ones or include a series of them, between these symptoms we can see: Before an allergy suspicion to food, it is necessary to relate the symptoms to the ingestion of some food. The Alergólogo will realize a few tests in the skin (Prick-Test) with allergens extracts, or with food in fresh air (Prick-Prick). If a reaction is reproduced urticarial in the proven area it will be considered to be the probability of an allergy to this been food. Then by means of a blood test the specific IgE (RAST-CAP) will measure itself to diverse food. If this analysis is positive for the same tested and positive food the suspicion is almost confirmed. Then it is possible to realize a provocation test with this food (which contains certain risk) or there is realized an exclusion of the same one of the diet. If the symptoms disappear it is considered to be the demonstrated food allergy. In the food allergy it is necessary to do a diet of exclusion of the implied food. If in a moment given the food it was not possible to have avoided for error: In case of an allergy of anaphylactic type to food proteins, Adreject should take ® 0,30 (Adults) or Adreject ® 0,10. (children of < 35 Kg). In case of allergic reaction for the accidental food proteins ingestion it is necessary to administer Adreject ® to dose of 0,30 cc/0,10 cc. With the preloaded syringe (autoinjector) it has only to narrow against the EXTERNAL PART OF THE THIGH. There is no need for an exact laying. NEVER REALIZE THE INJECTION IN THE BUTTOCK. On having pressed the autoinjector against the thigh, there is driven a wharf that activates the sucker, the needle is liberated in direction of the muscle and (adrenaline) expels the dose of epinefrina, and to come to Urgencies of the most nearby hospital. |
