Elevated DHEA-Sulfate: Clinical Significance and Diagnostic Approach
Primary Clinical Significance
- Elevated DHEAS reflects increased adrenal androgen secretion and serves as a marker for several distinct pathophysiologic processes, including primary adrenal insufficiency and adrenal hyperfunction or androgen excess syndromes, according to the American College of Endocrinology 1
- In primary adrenal insufficiency, DHEAS levels are characteristically low, not elevated, as stated by the Endocrine Society 2, 3, 1
- Elevated levels suggest adrenal hyperfunction or androgen excess syndromes, as recommended by the American Association of Clinical Endocrinologists 1
Major Causes to Consider
- Non-classical congenital adrenal hyperplasia must be ruled out first, particularly when DHEAS exceeds age-specific thresholds, as suggested by the Pediatric Endocrine Society (>3800 ng/ml for ages 20-29, >2700 ng/ml for ages 30-39) 1
- Polycystic ovary syndrome involves accelerated pulsatile GnRH secretion, insulin resistance, and metabolic dysregulation, according to the American College of Obstetricians and Gynecologists 1
Diagnostic Approach
- Look for specific signs of hyperandrogenism, including early-onset body odor, premature axillary or pubic hair, accelerated growth velocity, advanced bone age, and genital maturation in prepubertal children, as recommended by the American Academy of Pediatrics 1
- In postpubertal females, look for signs such as androgenetic alopecia and clitoromegaly, as suggested by the American College of Endocrinology 1
- Initial hormone panel should include free and total testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), sex hormone binding globulin (SHBG), and free androgen index, as recommended by the Endocrine Society 1
- Additional testing in selected cases may include insulin and glucose for metabolic assessment, as suggested by the American Diabetes Association 1
