Summary
Polyglandular autoimmune disease can cause progressive adrenal failure. Early monitoring of mineralocorticoid and glucocorticoid synthesis is crucial in children to detect adrenal insufficiency early.
Area of Science:
- Endocrinology
- Immunology
- Genetics
Background:
- Polyglandular autoimmune disease (PAd) is a group of rare disorders characterized by autoimmune-mediated failure of multiple endocrine glands.
- Early diagnosis and management are essential to prevent severe complications.
Observation:
- A pediatric patient with PAd presented with hypoparathyroidism and mucocutaneous candidiasis.
- Initial ACTH stimulation tests showed normal mineralocorticoid and glucocorticoid responses.
- At age 14, the patient developed hyponatremia, hyperkalemia, and growth failure, indicating progressive adrenal insufficiency.
Findings:
- Detailed ACTH testing revealed undetectable aldosterone production (zona glomerulosa failure) and deficient adrenal androgen synthesis (zona reticularis dysfunction).
- Glucocorticoid production (zona fasciculata) initially appeared normal but became impaired by age 19.
- Anti-adrenal antibodies targeting all three cortical layers were present.
Implications:
- This case highlights the potential for progressive adrenal failure in PAd, affecting all adrenal zones over time.
- Periodic monitoring of both mineralocorticoid and glucocorticoid synthesis is recommended in children with PAd, beyond electrolyte monitoring.
- Early detection of progressive adrenal insufficiency is vital for timely intervention and preventing long-term health issues.
