Overview

Anaphylaxis is a severe, whole-body allergic reaction to a chemical that has become an allergen. After being exposed to a substance such as bee sting venom, the person's immune system becomes sensitized to it. On a later exposure to that allergen, an allergic reaction may occur. This reaction happens quickly after the exposure, is severe, and involves the whole body.Tissues in different parts of the body release histamine and other substances. This causes the airways to tighten and leads to other symptoms. Anaphylaxis is life-threatening and can occur at any time. Risks include a history of any type of allergic reaction.

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. Anaphylaxis is itself a life threatening condition.

Common Causes

Anaphylaxis can occur in response to any allergen. Common causes include:

• Drug allergies (penicillins, cephalosporins, amphotericin B, nitrofurantoin, quinolones)

• Food allergies (peanuts, milk, eggs, seafood, nuts, grains, beans, gelatin in capsules)

• Insect bites/stings (yellow jacket, yellow and baldfaced hornets, paper wasp, honey bee, imported fire ants)

• Nonpollen allergen extracts (dust mites, dander of cats, dogs, horses and laboratory animals)

Causes by Organ System

• To obtain the coding for the table seen below, click here. You need to copy the table content from the edit box, and paste it into the edit box.
• You can then list the causes by organ system. List the causes, separated by a comma under the appropriate category where it says "No underlying causes". Erase "No underlying causes" if you are listing causes in that category.
• For an example of the causes by organ system table in a causes microchapter, click here.
