Summary
Hereditary angioedema (HAE) is a genetic disorder causing severe swelling attacks. Prompt treatment with C1-inhibitor concentrate effectively resolves acute HAE symptoms.
Area of Science:
- Immunology
- Genetics
Context:
- Hereditary angioedema (HAE) is an autosomal dominant disorder.
- Patients experience severe, recurrent swelling attacks affecting skin, gastrointestinal tract, and potentially airways.
- Laryngeal edema poses a life-threatening risk of airway obstruction.
Purpose:
- To describe the pathophysiology of Hereditary Angioedema.
- To highlight diagnostic challenges and methods.
- To present the therapeutic approach for acute HAE attacks.
Summary:
- HAE involves a deficiency in C1-inhibitor (C1-INH) activity, leading to complement and kinin system activation.
- Vasoactive peptides and kinins cause edematous swellings and pain.
- Misdiagnosis is common due to overlapping symptoms, particularly abdominal pain.
Impact:
- Accurate diagnosis of HAE is crucial for appropriate management.
- Intravenous C1-inhibitor concentrate provides rapid resolution of acute HAE symptoms.
- Understanding HAE pathophysiology aids in developing targeted therapies.
