Clinical information

Angioedema is a rapid, localized skin swelling that often affects deeper layers of the skin and mucosa. The swelling is usually non-itchy but can be painful. Here are some essential points:

• Angioedema can occur due to an allergic reaction or non-allergic causes.
• It often affects areas with loose tissues, such as the face, throat, and limbs.
• It may be accompanied by urticaria (hives), which is treated by serum urticaria therapy (autologous serum therapy).
• The condition can have adverse effects and become life-threatening if it causes airway obstruction.
• While this can be idiopathic, it can be caused by external causes, like latex, venomous insect bites, taking medication, or food that a person is allergic to.
• Depending on where the angioedema is located, it could lead to certain other consequences if left unaddressed, such as asphyxia, difficulty breathing, and death.
• Treatments include avoiding triggers, antihistamines, and steroids.
• Genetic angioedema is a hereditary condition requiring different treatment approaches.

Synonyms include

• Angioneurotic edema
• Allergic angioedema
• Anaphylactic shock
• Non-allergic angioedema
• Hereditary angioedema
