    Study Notes

    Adrenal Insufficiency

    • Adrenal insufficiency is a condition where the adrenal glands don't produce enough cortisol and aldosterone.
    • Three types exist: primary, secondary, and tertiary.
    • It is a common issue.
    • The Endocrine Society has created new guidelines for effective management.

    Primary Adrenal Insufficiency

    • Caused by dysfunction of the adrenal glands.
    • Common causes include autoimmune disease, congenital adrenal hyperplasia, and tuberculosis.
    • Symptoms: weakness, fatigue, anorexia, weight loss, hyperpigmentation, nausea, vomiting, hypotension, and hyperkalemia.
    • Hyperpigmentation arises from melanocyte-stimulating hormone in ACTH.
    • High ACTH and low cortisol levels are observed.
    • Diagnosis confirmed by ACTH and cortisol levels (not random cortisol).
    • Treatment involves replacing cortisol and aldosterone.
    • In a homeless patient with symptoms, primary adrenal insufficiency is a likely diagnosis.

    Secondary Adrenal Insufficiency

    • Caused by insufficient ACTH production from the pituitary gland.
    • Common causes include long-term steroid use and pituitary surgery.
    • Symptoms: weakness, fatigue, anorexia, weight loss, nausea, vomiting, hypotension, and hyperkalemia.
    • Low ACTH and low cortisol levels are observed.
    • Treatment usually involves replacing cortisol, potentially aldosterone as well.

    Tertiary Adrenal Insufficiency

    • Caused by insufficient corticotropin-releasing hormone from the hypothalamus.
    • Common causes include traumatic brain injury, meningitis, and stroke.
    • Symptoms: weakness, fatigue, anorexia, weight loss, nausea, vomiting, hypotension, and hyperkalemia.
    • Low ACTH and low cortisol levels are observed.
    • Treatment usually involves replacing cortisol, potentially aldosterone as well.

    Management of Adrenal Insufficiency

    • Patient education and medical alert (bracelet/necklace) are essential.
    • Dosage adjustments are needed based on illness or procedures.
    • Over-prescription of steroids is a concern, so monitoring for Cushingoid features and adjusting dosage is crucial.
    • A cortisol stimulation test differentiates between primary, secondary, and tertiary.
    • Treatment: cortisol and aldosterone (primary), cortisol (possibly aldosterone) in secondary and tertiary.
    • Tapering steroid medication is crucial to prevent flares, especially for those on steroids for more than three weeks. Use of pre-filled packs (short-term) and slow, gradual tapers (long-term) are recommended.
    • Patients should understand the risks of adrenal suppression.

    Cortisol Replacement

    • Hydrocortisone (10-20mg morning, 0-10mg evening) is preferred.
    • Prednisone (5-7.5mg daily) can be used.
    • Dosage adjustment is often needed (patients may be overmedicated).
    • Patients with primary adrenal insufficiency need injectable steroids (Solucortef) for emergencies.
    • Significant events (surgery, illness, trauma) require doubling the dose.

    Aldosterone Replacement

    • Fludrocortisone is the only recommended medication.
    • Dose is individualized based on patient needs.
    • Initiate with a low dose and increase as needed to address symptoms like hypotension, hyperkalemia, and fluid retention.

    Considerations for Tapering Steroids

    • Gradual tapering is needed for patients on steroids more than three weeks.
    • Guidelines for short-term and long-term tapering are provided (pre-filled packs and slow, gradual tapers).
    • Patients need to understand potential risks of adrenal suppression during tapering.

    Key Takeaways

    • Adrenal insufficiency is a complex, treatable condition.
    • Understanding different types and their management is critical.
    • Early diagnosis and treatment prevent complications.
    • Patient education and self-management are essential.

    Adrenal Insufficiency Diagnosis and Treatment

    • Cortisol Levels: Target mid-range levels (10-15) to avoid insufficiency or excess symptoms
    • Adrenal Stimulation Test: After hydrocortisone, test adrenal function, even if cortisol is in the mid-range.
    • Emergency Management: Suspected adrenal insufficiency needs immediate IV dexamethasone. It does not interfere with cortisol stimulation testing.
    • Dexamethasone Coverage: IV dexamethasone during testing ensures patient safety.
    • Hydration: D5 normal saline for hydration.
    • Hydrocortisone Replacement: Following the stimulation test, initiate hydrocortisone at 100 mg every 8 hours.
    • ACTH Levels: High ACTH indicates primary, low ACTH suggests secondary/tertiary.
    • Treatment Strategies: Primary needs cortisol and aldosterone, secondary/tertiary primarily cortisol.
    • Dosage Calculation: Cortisol dosage based on body surface area (formula provided).
    • Emergency Guidelines: Initially cover with dexamethasone, then do stimulation testing, adjust cortisol replacement with hydrocortisone 100mg every 8 hours and use D5 normal saline.
