Hereditary Angioedema in Pregnancy

Area of Science:

• Immunology
• Genetics
• Obstetrics

Background:

• Hereditary angioedema (HAE) is a rare genetic disorder causing unpredictable, potentially life-threatening swelling attacks.
• Pregnancy significantly impacts HAE course and treatment options, necessitating specialized care for women of childbearing age.
• Accurate diagnosis and understanding of HAE mechanisms are crucial for effective patient management.

Purpose of the Study:

• To provide a comprehensive overview of hereditary angioedema.
• To establish guidelines for managing pregnant patients with HAE.
• To inform clinicians on recognizing and treating HAE in pregnancy.

Main Methods:

• Literature search of English-language articles on PubMed and Ovid MEDLINE.
• Keywords used: "hereditary angioedema" and "pregnancy".
• Additional relevant articles identified from reference lists.

Main Results:

• Data synthesized from observational studies, case reports, and reviews indicate variable HAE presentation during pregnancy.
• Plasma-derived C1 inhibitor concentrate demonstrated safety and efficacy for acute attack treatment and prophylaxis in pregnant patients.
• Successful pregnancy and delivery are achievable with appropriate medical recognition, understanding, and management.

Conclusions:

• Clinicians should suspect HAE in cases of recurrent angioedema without urticaria or unexplained severe abdominal pain.
• Individualized treatment plans are essential for pregnant patients with HAE.
• Collaborative care involving experienced clinicians is vital for optimal outcomes.
