Addison’s disease
Introduction to Addison’s Disease
Welcome to the Addison’s Disease subsection of the Endocrinology for the MSRA course.
This section is designed to provide comprehensive and structured learning materials to help you understand and master the topic of Addison’s Disease.
Resources for Addison’s Disease:
- Addison’s Disease Revision Notes for the MSRA: Detailed and concise revision notes covering all essential aspects of Addison’s Disease, including its causes, symptoms, diagnosis, and treatment. These notes are based on UK NICE guidelines and are formatted in tables for easy recall.
- Addison’s Disease Flashcards for the MSRA: Interactive flashcards to help you memorise key facts and concepts about Addison’s Disease. These are perfect for quick reviews and reinforcing your knowledge.
- Addison’s Disease Accordion Q&A Notes for the MSRA: Engage in active learning with question-and-answer style revision notes in the accordion format. This is useful for testing your understanding of Addison’s Disease and focusing on areas needing improvement.
- Addison’s Disease Rapid Fire Quiz for the MSRA: A short quiz to test your knowledge and recall of Addison’s Disease-related concepts. It’s an excellent way to assess your progress and pinpoint areas for further review.
Key Points about Addison’s Disease:
- Definition: Addison’s Disease, also known as primary adrenal insufficiency, is a rare disorder where the adrenal glands do not produce sufficient steroid hormones, particularly cortisol and aldosterone.
- Causes: The most common cause is autoimmune destruction of the adrenal cortex. Other causes include infections (e.g., tuberculosis), metastatic cancer, and adrenal hemorrhage.
- Symptoms: Symptoms include fatigue, muscle weakness, weight loss, hypotension, hyperpigmentation, and salt craving. In severe cases, an Addisonian crisis can occur, presenting as acute hypotension and shock.
- Diagnosis: Diagnosis is based on clinical suspicion confirmed by laboratory tests showing low cortisol levels and high ACTH levels. The ACTH stimulation test can further confirm adrenal insufficiency. Electrolyte imbalances such as hyponatremia and hyperkalemia are common.
- Management: Management involves lifelong hormone replacement therapy with glucocorticoids (e.g., hydrocortisone) and mineralocorticoids (e.g., fludrocortisone). Patients need to be educated about stress dosing during illness or surgery to prevent adrenal crises.
- Complications: If not properly managed, complications include adrenal crisis, which is life-threatening and requires emergency treatment with IV hydrocortisone and fluids.
We hope you find these resources helpful and engaging as you prepare for the MSRA. Be sure to explore other related endocrinology topics to enhance your preparation.
