Adrenal Insufficiency

Adrenal insufficiency (AI) is a life-threatening endocrine disorder characterized by the inadequate production or action of adrenal cortex hormones, primarily cortisol. It is classified into primary (destruction of the adrenal cortex), secondary (pituitary ACTH deficiency), and tertiary (hypothalamic CRH deficiency).

• Primary AI: Primarily caused by autoimmune adrenalitis (Addison's disease, ~80% of cases in developed nations), infections (tuberculosis, HIV, fungal infections), bilateral adrenal hemorrhage, metastases, or genetic disorders like Congenital Adrenal Hyperplasia (CAH).
• Secondary/Tertiary AI: Most commonly caused by the abrupt cessation of chronic exogenous glucocorticoid therapy. Other causes include pituitary tumors, hypothalamic-pituitary surgery, or head trauma.

In primary AI, destruction of the adrenal cortex leads to a deficiency of both glucocorticoids (cortisol) and mineralocorticoids (aldosterone). Cortisol deficiency impairs gluconeogenesis, reduces vascular reactivity to catecholamines, and decreases free water clearance. Aldosterone deficiency results in renal sodium wasting, potassium retention, and hypovolemia. In secondary and tertiary AI, mineralocorticoid production remains largely intact because aldosterone secretion is regulated primarily by the renin-angiotensin-aldosterone system (RAAS), not ACTH.

• Primary AI: Prevalence is 100 to 140 cases per million individuals. It most frequently presents in adults aged 30 to 50 years, with a female-to-male ratio of 2:1 in autoimmune cases.
• Secondary/Tertiary AI: Prevalence is higher, estimated at 150 to 280 cases per million, driven largely by therapeutic glucocorticoid use.

• Long-term systemic corticosteroid therapy.
• Co-existing autoimmune conditions (e.g., Type 1 Diabetes, Hashimoto's thyroiditis).
• History of pituitary or brain surgery/radiation.
• Severe infections or sepsis (Waterhouse-Friderichsen syndrome).

• Vital Signs: Hypotension (notably orthostatic), tachycardia, fever (during crisis).
• Inspection: Hyperpigmentation of palmar creases, buccal mucosa, scars, and friction points (primary AI only). Vitiligo may be seen in autoimmune etiologies. Loss of axillary and pubic hair in females due to adrenal androgen deficiency.
• Palpation: Diffuse abdominal tenderness without rebound or guarding.

CT Scan of the Abdomen: Purpose: Evaluate adrenal glands. Typical Findings: Bilateral adrenal atrophy in autoimmune etiology; enlargement, calcifications, or masses in infectious, hemorrhagic, or neoplastic causes. Clinical Importance: Differentiates autoimmune destruction from secondary pathologic processes.
MRI of the Brain (Sella Turcica): Purpose: Evaluate the pituitary and hypothalamic regions. Typical Findings: Pituitary macroadenoma, microadenoma, pituitary atrophy, or "empty sella." Clinical Importance: Indicated in secondary and tertiary adrenal insufficiency to identify structural central lesions.

• Hypothyroidism: Presents with fatigue and weight gain (unlike weight loss in AI). Differentiated by elevated TSH and low free T

• Anorexia Nervosa: Characterized by severe weight loss but lacks hyperpigmentation, hyperkalemia, or abnormal ACTH stimulation.
• Sepsis: Presents with refractory hypotension, but will typically show normal or elevated cortisol levels unless complicated by adrenal hemorrhage.

• Adrenal Crisis (acute hypovolemic and distributive shock).
• Osteoporosis (from excessive glucocorticoid replacement).
• Metabolic syndrome and cardiovascular disease (due to chronic over-replacement).

With consistent hormone replacement therapy, life expectancy is near-normal. Quality of life can be mildly reduced due to fatigue and the constant threat of adrenal crisis. The prognosis is poor if an adrenal crisis is unrecognized or untreated, as it carries a high mortality rate.

• Primary Prevention: Gradual tapering of exogenous glucocorticoids rather than sudden cessation to allow the hypothalamic-pituitary-adrenal (HPA) axis to recover.
• Secondary Prevention: Early initiation of "stress dosing" (doubling or tripling oral steroid doses) during minor illnesses, trauma, or surgery to prevent adrenal crisis.
