The portal for rare diseases and orphan drugs

Hereditary angioedema type 3 (HAE 3) is a form of hereditary angioedema (see this term) characterized by acute edema in subcutaneous tissues, viscera and/or the upper airway.

What is the most common cause of angioedema?

Allergies. Angioedema is often the result of an allergic reaction. This is where the body mistakes a harmless substance, such as a certain food, for something dangerous. It releases chemicals into the body to attack the substance, which cause the skin to swell.

What causes sudden angioedema?

Substances known to trigger allergic angioedema include: certain types of food – particularly nuts, shellfish, milk and eggs. some types of medication – such as penicillin, aspirin and non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen. insect bites and stings – particularly wasp and bee stings.

What is severe angioedema?

Angioedema is swelling underneath the skin. It’s usually a reaction to a trigger, such as a medicine or something you’re allergic to. It is not normally serious, but it can be a recurring problem for some people and can very occasionally be life-threatening if it affects breathing.

What autoimmune disease causes angioedema?

In an estimated 30–50% of the cases, idiopathic angioedema may be associated with an underlying autoimmune disease, such as systemic lupus erythematosus (SLE).

How do you test for angioedema?

Tests you may have include: a skin prick test – your skin is pricked with a tiny amount of the suspected allergen to see whether there’s a reaction. a blood test – a sample of your blood is tested to determine whether your immune system reacts to a suspected allergen.

What doctor treats angioedema?

An allergist-immunologist is a doctor who diagnoses and treats conditions of the immune system, including asthma, allergies, and HAE. C1-INH, the protein that is lacking in HAE, is part of your immune system. An allergist-immunologist may have diagnosed you with HAE. This doctor will plan and oversee your treatment.

Can stress and anxiety cause angioedema?

Who is most at risk for angioedema?

Over the past 30 years in the United States, 55% of angioedema deaths connected to ACE-I use were among Blacks. In contrast, 60% of hereditary angioedema cases in the United States are in Caucasian patients.

What foods trigger angioedema?

Most of the food mentioned by the investigated subjects such as cheese, alcoholic beverages, fish, tomatoes, strawberries, pineapples, nuts, citrus fruits and kiwis contain or release histamine [22]. Therefore a histamine intolerance reaction is probably associated with the induction of angioedema.
