Angioedema in Children

Overview

Angioedema is a condition that causes swelling beneath the skin, often affecting areas like the eyes, lips, throat, and sometimes the hands, feet, or genitals. It is often related to allergic reactions but can also be triggered by certain medications or genetic factors. In some cases, angioedema can become serious if the swelling affects breathing, particularly when it involves the throat. While many cases resolve on their own, severe cases need immediate medical attention.

Symptoms

Angioedema symptoms typically develop suddenly and may include:

  • Swelling: Usually affects areas around the eyes, lips, tongue, or throat.
  • Red or pink skin: The swollen areas may look red or feel warm, but the swelling is usually not itchy.
  • Breathing difficulties: If the swelling occurs in the throat, it can block the airway, making it hard to breathe.
  • Abdominal pain: Sometimes, the swelling occurs inside the digestive tract, causing stomach cramps or discomfort.
  • Tightness in affected areas: A feeling of tightness or fullness in swollen parts of the body.

Causes

Angioedema can be caused by several factors, including:

  • Allergies: The most common cause, often triggered by foods (like nuts or shellfish), medications, insect bites, or environmental allergens.
  • Medications: Certain medications, particularly ACE inhibitors used to treat high blood pressure, can cause angioedema as a side effect.
  • Hereditary angioedema (HAE): This is a rare genetic condition where the body lacks a specific protein that helps regulate swelling.
  • Infections: Viral infections may trigger episodes of angioedema in some children.
  • Unknown causes: Sometimes, the cause of angioedema is not clear, and it is referred to as idiopathic angioedema.

Diagnosis

To diagnose angioedema, doctors will:

  • Review medical history: Understanding any recent exposure to allergens, medications, or family history of hereditary angioedema.
  • Perform a physical exam: Checking for swelling in areas like the face, throat, or extremities.
  • Blood tests: These may be done to check for allergies or underlying genetic conditions like hereditary angioedema.
  • Skin allergy tests: Used to identify potential allergens that may have triggered the reaction.
  • Imaging tests: In severe cases, imaging (like a CT scan) may be used to assess swelling in internal organs or airways.

Treatment Options

The treatment for angioedema depends on the cause and severity of the swelling. At Gertrude’s Children’s Hospital, we offer a comprehensive treatment approach, which includes:

  • Antihistamines: These help reduce swelling and allergic reactions, particularly for allergy-induced angioedema.
  • Corticosteroids: Used to reduce inflammation and prevent the swelling from getting worse.
  • Epinephrine: In cases of severe angioedema where the throat or airways are involved, an epinephrine injection may be necessary to prevent life-threatening complications.
  • Specialized care for hereditary angioedema (HAE): Children with HAE may need specific treatments like C1 inhibitors to control swelling episodes.
  • Avoidance and prevention: If the cause of the angioedema is identified, avoiding the triggering allergen or medication is crucial.

Angioedema in Children

Angioedema can be caused by an allergic reaction, but it is a specific type of swelling beneath the skin. Not all cases of angioedema are due to allergies—some are caused by medications or are hereditary.

Most cases of angioedema resolve within a few days, but if the swelling is due to a hereditary cause or medications, it may require ongoing management.

If the cause of angioedema is known, avoiding the trigger (such as certain foods, medications, or allergens) is the best way to prevent it. For children with hereditary angioedema, a specialized treatment plan can help manage and reduce episodes.

If your child has swelling in the throat, difficulty breathing, or signs of anaphylaxis, seek emergency medical care immediately. For milder symptoms, contact your pediatrician for guidance.
