Evaluation and Management of Elevated DHEA

When DHEA or DHEA-S is elevated in an adult, immediately measure testosterone levels and assess for virilization signs; if testosterone is more than twice the upper limit of normal, obtain DHEA-S levels to differentiate adrenal from ovarian sources, with DHEA-S >600 µg/dL (16,000 nmol/L) indicating adrenal adenoma requiring urgent abdominal imaging. 1

Initial Diagnostic Approach

Critical First Steps

When confronted with elevated DHEA, the priority is determining whether this represents:

  • Adrenal pathology (adenoma, carcinoma, or hyperplasia)
  • Ovarian pathology (tumor or hyperthecosis)
  • Congenital adrenal hyperplasia (nonclassic form)

Testosterone Assessment

Measure total testosterone as the next immediate step 1:

  • If testosterone ≥2× upper limit of normal: This is a red flag requiring urgent evaluation

    • Obtain DHEA-S measurement (DHEA-S is more stable and primarily adrenal in origin)
    • DHEA-S >600 µg/dL strongly suggests adrenal cortical adenoma
    • Proceed immediately to abdominal CT or MRI to identify tumor 1

  • If DHEA-S is normal but testosterone remains elevated: Consider ovarian sources

    • Ovarian hyperthecosis (associated with insulin resistance)
    • Androgen-secreting ovarian tumor
    • Both are LH-dependent and can be suppressed by GnRH agonists, estrogen-progestogen, or cyproterone acetate 1

Additional Essential Testing

Measure 17-hydroxyprogesterone (17OHP) to screen for nonclassic 21-hydroxylase deficiency, which can present with isolated DHEA elevation 1

Assess SHBG levels 1:

  • Typically reduced in obesity, metabolic syndrome, or family history of diabetes
  • Allows calculation of free or bioavailable testosterone
  • Helps interpret total testosterone values more accurately

Consider Δ4-androstenedione: May show isolated elevation even when testosterone is normal, particularly with reduced SHBG 1

Clinical Context Matters

Timing and Medication Considerations

Ensure proper assay conditions 1:

  • Verify menstrual cycle phase (if applicable)
  • Discontinue thyroid hormones or estrogenic medications that increase SHBG
  • Avoid antiepileptic agents like valproate that affect SHBG

Physical Examination Focus

Document specific findings 2:

  • Virilization signs: clitoromegaly, deepening voice, male-pattern baldness
  • Hirsutism severity: Use standardized scoring (Ferriman-Gallwey)
  • Acne and seborrhea distribution and severity
  • Body habitus: BMI, waist-to-hip ratio (normal <0.8 in women)
  • Acanthosis nigricans: Suggests insulin resistance

Management Based on Source

Predominantly Adrenal Hyperandrogenism

Glucocorticoid therapy is first-line 2:

  • Prednisone 5-7.5 mg OR dexamethasone 0.25-0.5 mg daily after supper
  • Continue for 2-3 months, then reassess androgens
  • If normalized, reduce to prednisone 5 mg or dexamethasone 0.25 mg for 2-3 months
  • Can then halve dose or discontinue
  • Monitor androgens every 3-4 months for 1 year

Expected outcomes 2:

  • DHEA-S typically remains suppressed indefinitely
  • Testosterone more likely to recur than DHEA-S
  • Sustained improvement in acne
  • Minor effect on hirsutism (slower growth, softer hair)
  • Improved ovulatory function and fertility

Combined Ovarian and Adrenal Sources

Combination therapy 2:

  • Oral contraceptives (suppress ovarian androgens) PLUS
  • Low-dose glucocorticoids (suppress adrenal androgens)
  • Consider adding spironolactone 50-200 mg daily as antiandrogen

Predominantly Ovarian Hyperandrogenism

Hormonal suppression 2:

  • Oral contraceptives (estrogen-progestogen combinations)
  • GnRH agonists with estrogen "add-back" therapy
  • Antiandrogens: spironolactone (preferred) or flutamide (use cautiously due to hepatotoxicity risk)

Critical Pitfalls to Avoid

  1. Don't dismiss normal testosterone with clear hyperandrogenic symptoms: Normal testosterone requires careful interpretation; measure DHEA-S, androstenedione, and free testosterone 1

  2. Don't delay imaging with very high DHEA-S: Values >600 µg/dL demand urgent tumor evaluation 1

  3. Avoid flutamide except in severe refractory cases: Risk of fatal hepatotoxicity 2

  4. Don't use ketoconazole or cimetidine: Ineffective or dangerous for hyperandrogenism 2

  5. Remember contraception: Antiandrogens, insulin sensitizers, and 5α-reductase inhibitors are contraindicated in pregnancy 2

Metabolic Considerations

Elevated DHEA-S correlates with increased metabolic syndrome risk in elderly men 3, so assess:

  • Fasting glucose and lipids
  • Blood pressure
  • Waist circumference
  • Consider insulin resistance evaluation
