Hereditary angioedema
Introduction to Hereditary Angioedema
Welcome to the Hereditary Angioedema subsection of the Haematology for the MSRA course.
This section is designed to provide comprehensive and structured learning materials to help you understand and master the topic of Hereditary Angioedema for the MSRA.
Hereditary angioedema (HAE) is a rare genetic disorder characterised by recurrent episodes of severe swelling (angioedema) in various parts of the body, including the skin, gastrointestinal tract, and airways. It is caused by a deficiency or dysfunction of C1 esterase inhibitor (C1-INH).
In this subsection, you will find the following resources to aid your revision:
- Hereditary Angioedema Revision Notes for the MSRA: Detailed and concise revision notes covering all essential aspects of Hereditary Angioedema, including its causes, symptoms, diagnosis, and treatment. These notes are designed using UK NICE guidelines and are displayed in a table format for easy recall. Use the notes to gain an initial understanding of the topic.
- Hereditary Angioedema Flashcards for the MSRA: Interactive flashcards to help you memorise key facts and concepts about Hereditary Angioedema. These are perfect for quick reviews and reinforcing your knowledge.
- Hereditary Angioedema Accordion Q&A Notes for the MSRA: A unique feature where you can test your understanding of Hereditary Angioedema with question-and-answer style revision notes. This format helps in active learning and retention of important information. It is useful if you are running low on time as you can cover weak areas easily.
- Hereditary Angioedema Rapid Fire Quiz for the MSRA: A short quiz to test your knowledge and recall of Hereditary Angioedema-related concepts. This is an excellent way to assess your progress and identify areas that need further review.
Key Points about Hereditary Angioedema:
- Definition: Hereditary angioedema (HAE) is a genetic disorder characterised by recurrent episodes of swelling in various parts of the body due to a deficiency or dysfunction of C1 esterase inhibitor (C1-INH).
- Causes: It is an inherited condition caused by mutations in the SERPING1 gene, leading to low levels or dysfunction of C1-INH.
- Symptoms: Episodes of swelling, often affecting the face, extremities, gastrointestinal tract (causing abdominal pain), and airways (which can be life-threatening if not treated).
- Diagnosis: Diagnosis is made through clinical evaluation and confirmed by measuring C1-INH levels and function, as well as C4 levels in the blood.
- Management: Management includes acute treatment with C1-INH concentrates, icatibant, or ecallantide, and long-term prophylaxis with androgens or lanadelumab in severe cases.
- Complications: If untreated, HAE can lead to life-threatening airway swelling, requiring emergency intervention.
We hope you find these resources helpful and engaging as you prepare for the MSRA. Don’t forget to explore related topics in the haematology section to broaden your knowledge.
