peanut allergyImmunology A common cause of anaphylactic reactions which, unlike some allergies, is rarely outgrown; PA is the most common cause of food allergy in the US, and a leading cause of food-induced anaphylaxis and death after accidental exposure
People with known allergies to peanuts must avoid eating raw or processed peanuts and also products containing or prepared with peanut oil . Those affected by peanut allergy should learn to watch for the signs of anaphylaxis (hives, pruritus, rashes in the skin creases, shortness of breath, choking, wheezing, stridor). People with known anaphylaxis to peanuts should carry epinephrine injectors and use them at the onset of a hypersensitivity reaction. (Repeated use may be necessary in persistent reactions.) Cross-reactivity to other legumes (peas, soy products) may affect some people and pose important health risks. Affected people should wear medical alert bracelets or necklaces identifying their condition. Densensitization can be accomplished with modified peanut allergens.
