Pediatric Adrenal Insufficiency: Challenges and Solutions

Area of Science:

• Pediatric Endocrinology
• Endocrinology
• Internal Medicine

Background:

• Adrenal insufficiency is often misdiagnosed, mimicking sepsis or cardiovascular disease.
• In newborns, cortisol deficiency can delay bile acid maturation, causing prolonged cholestatic jaundice.
• Subclinical adrenal insufficiency presents a diagnostic challenge, often requiring dynamic testing.

Purpose of the Study:

• To highlight the diagnostic challenges of adrenal insufficiency.
• To emphasize the importance of dynamic testing for assessing the hypothalamic-pituitary-adrenal axis.
• To discuss management strategies including glucocorticoid replacement therapy.

Main Methods:

• Review of diagnostic approaches for adrenal insufficiency.
• Emphasis on corticotropin analog stimulation tests as first-line diagnostic tools.
• Discussion of long-term glucocorticoid replacement therapy, including modified-release hydrocortisone.

Main Results:

• A single cortisol value is often insufficient for diagnosis.
• Dynamic testing is essential for accurate assessment of adrenal function.
• Prompt treatment of acute adrenal crisis is critical for patient survival.

Conclusions:

• Adrenal insufficiency requires careful diagnosis, often necessitating dynamic testing.
• Long-term glucocorticoid replacement is standard care, with hydrocortisone as a primary treatment.
• Timely intervention for acute adrenal crisis is paramount to prevent mortality.
