What is Angioedema and What Causes it?

Angioedema is a condition characterized by the swelling of the deeper layers of skin due to fluid build-up. This swelling often appears around the eyes, lips, genitals, hands, and feet, but it can affect any body part. Many people who suffer from angioedema also experience hives or urticaria, which presents as a raised itchy rash. The cause of angioedema can vary and can include abdominal pain, insect bites or stings, and certain medications or food allergies. In some cases, there may be no known trigger. Blood tests are usually required to help make a diagnosis as well as to rule out other conditions that may mimic angioedema symptoms, such as acute urticaria or an autoimmune disorder.

Understanding Angioedema

Types of Angioedema

Angioedema is classified into two types: acute and recurrent angioedema. Acute attacks are generally mild symptoms that resolve within twenty-four hours without treatment; however, if left untreated they can become serious medical emergencies, especially if the throat swells shut, making it difficult to breathe. Recurrent Angioedema, on the other hand, is defined as having at least three episodes more than six weeks apart within one year with no known trigger.

Treatment for both types of angioedema will depend on the cause; however, emergency medical attention should be sought if you experience any severe symptoms, such as difficulty breathing or severe abdominal pain. Your healthcare provider will take your medical history, including any family history of allergies, and perform a physical examination along with possible blood tests in order to make a diagnosis and develop an individualized treatment plan for you.

Angioedema Treatment Medications

The appropriate therapeutic approach for angioedema is contingent upon the specific types and severity levels of the condition. The following is a comprehensive list of the commonly prescribed medications used to effectively alleviate symptoms of angioedema.

Histamine H1 Antagonist Medications

These drugs, commonly referred to as antihistamines, serve as a primary treatment for both allergic and idiopathic angioedema. Their function is to counteract the effects of histamine, a compound that the body releases during an allergic reaction, which triggers inflammation and swelling. This is why antihistamines are typically the first course of action when treating allergic angioedema.

Glucocorticosteroid Medications

Glucocorticosteroids, or corticosteroids, are anti-inflammatory medications that can help reduce swelling and inflammation in cases of allergic and idiopathic angioedema. These medications work by binding to specific receptors in cells that are signaling molecules to contribute to inflammation and swelling. By reducing the production of these molecules, corticosteroids can effectively reduce the inflammation and swelling associated with angioedema.

Kinetin

Kinetin is a plant hormone that has been shown to have the potential for treating hereditary angioedema by increasing the production of the C1-inhibitor protein.

Biologics

Biologic medications, such as monoclonal antibodies, can be used to treat certain types of angioedema by targeting specific proteins or cells involved in the inflammatory response.

Androgenic Steroids

Androgenic steroids are synthetic derivatives of the male hormone testosterone and can be used to treat hereditary angioedema. These medications (such as danazol) will increase the production of a protein called C1-inhibitor, which helps control inflammation and swelling.

ACE Inhibitors

Angiotensin-converting enzyme (ACE) inhibitors are medications used to treat high blood pressure, but they can also cause drug-induced angioedema. In such cases, referred to as ACEi-induced angioedema, alternative medications may be prescribed to manage the condition.

C1-Inhibitor Concentrates

A deficiency or dysfunction of the C1-inhibitor can lead to excessive release of inflammatory mediators. C1-Inhibitor Concentrates are used to treat hereditary angioedema by replacing the missing or dysfunctional C1-inhibitor protein in the body.

Xolair

Xolair (omalizumab) is an anti-IgE medication used to treat chronic idiopathic angioedema and allergic angioedema that is not responsive to other treatments.

Omalizumab

Omalizumab is a monoclonal antibody medication that can be used to treat chronic idiopathic angioedema by blocking the action of immunoglobulin E (IgE), a protein involved in allergic reactions.

Danazol

Danazol is an androgenic steroid medication used to treat hereditary angioedema by increasing the production of C1-inhibitor protein. In individuals with hereditary angioedema, there is a deficiency or dysfunction in the C1-inhibitor protein, which leads to recurrent attacks of angioedema.

Biologics or Anti-IgE Immunotherapy

Biologic medications or immunotherapy target specific proteins or cells involved in the inflammatory response and can help manage angioedema symptoms. Biologic medications may offer advantages over other therapies for angioedema, such as corticosteroids or antihistamines, due to their specificity and targeted ability.

Choosing the Right Doctor for Angioedema Care

When choosing a doctor to treat angioedema, it is important to find someone who has experience in dealing with the condition. You should seek out a healthcare provider or specialist who is knowledgeable about the common types of angioedema and can provide adequate treatment for your specific case. For severe cases, such as throat swelling or chronic urticaria, it may be beneficial to consult with an allergist or plastic surgeon that specializes in treating angioedema.

It is also important to have a plan of action in place for acute treatment of angioedema when needed. The best healthcare provider for you should be able to provide guidance on medications and lifestyle changes that can help reduce symptoms and manage the condition over time. Additionally, they should also be able to provide support and resources that can help you better understand your condition and learn how best to manage it over time.

CLINICAL DIAGNOSIS

Diagnostic Tests to Check for Angioedema Symptoms

For those suffering from severe angioedema, a healthcare provider may be able to diagnose the condition based on a physical exam and a review of symptoms. If an inhibitor deficiency is suspected, laboratory tests may be ordered to confirm the diagnosis. These tests can include checking for levels of C1-inhibitor protein in the blood, as well as screening for any underlying genetic conditions that could be causing angioedema. If an allergic reaction or anaphylactic reaction is suspected, allergy testing or referral to an allergy specialist may be necessary. Ultimately, a plastic surgeon who specializes in treating angioedema can help with diagnosing and managing this condition.

Avoiding known allergens or irritants
Managing stress through relaxation techniques, such as meditation or yoga
>Eating a healthy diet
Prioritizing sleep and self-care
Quitting smoking and limiting alcohol consumption
Following your healthcare provider’s recommendations for preventive medications and other treatments

Frequently Asked

Questions About Angioedema Treatment

How many types of angioedema exist?

There are four primary categories of angioedema: those caused by allergies, those with unknown origins (idiopathic), those triggered by medications, and those that are genetic (hereditary). Each type has specific causes and may require different treatment methods. The type can often be determined with a physical examination, but there are blood tests that can help differentiate which one a patient has. Genetic testing is also available to rule out hereditary angioedema.

How long does it take for angioedema to go away?

Angioedema symptoms usually appear suddenly and last for 1 to 3 days. However, the duration may vary depending on the severity and cause of the condition. It’s essential to seek medical attention if you experience difficulty breathing or severe swelling, as these can be signs of a more serious issue.

Is angioedema a common problem?

Yes, the condition affects 10-20% of people during their life, with the most common cause being an allergic reaction. However, hereditary angioedema is a rare form that affects between 1 in 10,000 to 1 in 50,000 people. In many cases, the cause is never found, or idiopathic.

What can cause angioedema besides foods?

In addition to trigger foods, the body can react to animal dander or saliva, sunlight, water, cold or heat, pollen, certain medicines, or autoimmune diseases.
