Acquired Angioedema: Symptoms, Diagnosis and Treatment Care

• Drug-Induced Angioedema: Caused by a reaction to certain medications, leading to swelling in the deeper layers of the skin.
• Idiopathic Angioedema: Occurs without an identifiable cause, resulting in sudden swelling typically in the face, lips, or throat.
• Angiotensin Converting Enzyme (ACE) Inhibitor Induced Angioedema: Linked to the use of medications that affect blood pressure regulation, causing swelling, especially in the face and throat.
• Hereditary Angioedema (HAE): Type 1 and Type Inherited condition resulting in recurrent episodes of swelling in various body parts due to a deficiency or dysfunction of the C1 inhibitor protein.
• Acquired C1 Esterase Inhibitor Deficiency: Occurs due to the development of antibodies against C1 inhibitor protein, leading to episodes of angioedema.

• Swelling of the skin
• Swelling of the mucous membranes
• Abdominal pain
• Nausea and vomiting

• Autoimmune disorders
• Medications
• Lymphoproliferative disorders
• Solid tumors
• Infections
• Allergic reactions
• Underlying medical conditions

• Recurring episodes of unexplained swelling in the face, lips, hands, or abdomen without an obvious allergic trigger.
• Swelling that lasts more than 24-72 hours or does not respond to standard antihistamine treatment.

• You experience swelling of the tongue, throat, or airway, causing difficulty breathing or swallowing.
• Sudden severe abdominal pain or vomiting occurs alongside swelling, indicating a visceral attack.
• You feel faint, have a hoarse voice, or notice your throat tightening rapidly.

• Blood tests
• Skin prick test
• Allergy testing
• Complement testing

• Antihistamines are commonly used to relieve symptoms of Acquired Angioedema by blocking the effects of histamine, which is involved in allergic reactions and swelling.

• Corticosteroids help reduce inflammation and swelling in Acquired Angioedema by suppressing the immune system's response that leads to the swelling.

• Ecallantide is a medication that can be used to treat Acquired Angioedema attacks by inhibiting a protein involved in the inflammatory response that causes swelling.

• Icatibant is a medication that works by blocking the effects of a specific chemical involved in the body's inflammatory response, thereby reducing swelling in Acquired Angioedema.

• In some cases of Acquired Angioedema, infusion of fresh frozen plasma may be used to replace deficient proteins in the blood that are responsible for regulating inflammation and preventing swelling.

While acquired angioedema cannot always be prevented, certain measures can help reduce the frequency and severity of attacks and lower the risk of complications:

• Identify and avoid triggers: Work with your healthcare provider to recognize factors that may provoke swelling episodes and avoid them whenever possible.
• Manage underlying conditions: Treating associated disorders, such as autoimmune diseases or lymphoproliferative conditions, may help control acquired angioedema.
• Avoid certain medications: Some medicines, particularly ACE inhibitors, can worsen angioedema and should be avoided if recommended by your doctor.
• Follow prescribed treatment plans: Taking medications as directed and attending regular follow-up appointments can help prevent recurrent attacks.
• Reduce stress: Emotional stress may trigger symptoms in some individuals, so stress-management techniques may be beneficial.
• Inform healthcare providers: Let doctors and dentists know about your condition before undergoing medical or dental procedures that could trigger swelling.
• Monitor symptoms closely: Early recognition of swelling episodes allows for prompt treatment and may prevent severe complications.
• Carry emergency information: Keeping medical identification and emergency contact information readily available can help ensure timely care during an attack.

Regular medical care and proactive management of underlying conditions are important steps in reducing the impact of acquired angioedema and improving quality of life.
