1

a type of antigen that produces an abnormally vigorous immune response in which the immune system fights off a perceived threat that would otherwise be harmless to the body.

such as dust mite excretion, pollen, pet dander or even royal jelly

some foods such as peanuts (a legume), nuts, seafood and shellfish are the cause of serious allergies in many people.

allergens

2

life-threatening allergic reaction

allergic reaction

3

life-threatening allergic reaction also known as anaphylactic shock and anaphylaxis

anaphylactic reaction

4

sudden, severe allergic reaction characterized by a sharp drop in blood pressure, urticaria, and breathing difficulties that is caused by exposure to a foreign substance, such as a drug or bee venom, after a preliminary or sensitizing exposure

S/S
dizziness, loss of consciousness, labored breathing, swelling of the tongue and breathing tubes, blueness of the skin, low blood pressure, heart failure, and death.

anaphylactic shock

5

resembling generalized anaphylaxis but not caused by IgE-mediated allergic reaction but rather by a nonimmunologic mechanism

anaphylactoid reaction

6

sudden, severe allergic reaction characterized by a sharp drop in blood pressure, urticaria, and breathing difficulties that is caused by exposure to a foreign substance, such as a drug or bee venom, after a preliminary or sensitizing exposure


S/S
dizziness, loss of consciousness, labored breathing, swelling of the tongue and breathing tubes, blueness of the skin, low blood pressure, heart failure, and death.

anaphylaxis

immune system

16

17

when a person is expose to the an allergen again the Ige antibody is present, anaphylactic reaction may occur. its a hypersensitivity

non-lgE-mediated reaction

18

exposure to allergen that results in the development of hypersensitivity.

sensitization
