What are the treatment options for a female patient with elevated Dehydroepiandrosterone (DHEA) levels, presenting with symptoms of hyperandrogenism, such as hirsutism or acne, and potentially Polycystic Ovary Syndrome (PCOS) or insulin resistance?

Treatment of Elevated DHEA in Females with Hyperandrogenism

First-Line Treatment Recommendation

Combined oral contraceptives (COCs) are the first-line treatment for hyperandrogenism in women with elevated DHEA, effectively regulating menstrual cycles and reducing androgen excess 1.

Initial Diagnostic Clarification

Before initiating treatment, confirm the clinical context:

  • Elevated DHEA-S occurs in only 8-33% of PCOS patients and is not a first-line diagnostic marker due to poor specificity compared to total or free testosterone 1.

  • Age-adjusted reference ranges are critical when interpreting DHEA-S, as levels peak between ages 20-30 and decline steadily thereafter 1. Using inappropriate reference ranges leads to overdiagnosis.

  • Rule out androgen-secreting tumors if DHEA-S exceeds age-adjusted thresholds (age 20-29: >3800 ng/ml; age 30-39: >2700 ng/ml) 2, or if total testosterone is markedly elevated (>8.7 nmol/L or 250 ng/dl) with rapid-onset virilization 1, 3.

  • Exclude non-classic congenital adrenal hyperplasia with morning 17-hydroxyprogesterone testing if DHEA-S is significantly elevated 1.

Treatment Algorithm

Step 1: Combined Oral Contraceptives (First-Line)

  • COCs are recommended as first-line therapy by the American College of Obstetricians and Gynecologists for managing hyperandrogenism, including hirsutism and acne 1.

  • COCs suppress ovarian androgen production and increase sex hormone-binding globulin (SHBG), thereby reducing free testosterone 1.

  • Clinical improvement in hirsutism and acne typically requires 6-12 months of continuous therapy 4.

Step 2: Add Antiandrogens if COCs Alone Are Insufficient

If hyperandrogenic symptoms persist after 6 months of COC therapy:

  • Spironolactone (50-200 mg daily) is the preferred antiandrogen for treating hirsutism and acne in PCOS 4.

  • Lower doses (50-100 mg daily) are as efficacious as higher doses with fewer side effects and reduced cost 4.

  • Flutamide and finasteride are alternative antiandrogens but have more significant side effect profiles 4. Flutamide carries hepatotoxicity risk and requires monitoring 5.

  • Always combine antiandrogens with COCs to prevent pregnancy, as these agents are teratogenic 5, 4.

Step 3: Address Insulin Resistance and Metabolic Dysfunction

  • Screen for insulin resistance with fasting glucose and 2-hour oral glucose tolerance test 1.

  • Metformin (500 mg three times daily) significantly reduces testosterone and DHEA-S levels in women with PCOS and hyperinsulinemia 6, 7.

  • Metformin is particularly effective in patients with elevated DHEA-S, leading to improvements in menstrual cycle regularity, BMI, hirsutism, and acne 6.

  • Patients with normal DHEA-S show less improvement in hirsutism with metformin compared to those with elevated DHEA-S 7.

  • Lifestyle modifications (diet and exercise) are essential for overweight/obese patients to improve insulin sensitivity 1.

Important Clinical Considerations

When to Suspect Adrenal or Ovarian Tumors

  • Total testosterone >8.7 nmol/L (250 ng/dl) has 100% sensitivity but only 9% positive predictive value for androgen-secreting neoplasms 3.

  • DHEA-S >16.3 μmol/L (6000 ng/ml) warrants adrenal imaging to exclude adrenocortical carcinoma 1, 3.

  • Rapid-onset virilization (deepening voice, clitoromegaly, severe acne) mandates immediate imaging regardless of hormone levels 1.

DHEA-S Elevation in Different PCOS Phenotypes

  • Non-classic PCOS phenotypes (B and C) have higher prevalence of elevated DHEA-S compared to classic phenotype A 8.

  • Phenotype A patients with elevated DHEA-S have lower BMI and insulin levels, while phenotypes B and C show the opposite pattern 8.

  • This suggests adrenal hyperandrogenism may be influenced by metabolic factors in non-classic phenotypes 8.

Monitoring and Follow-Up

  • Reassess clinical symptoms (hirsutism, acne, menstrual regularity) at 3-6 month intervals 1.

  • Repeat morning testosterone and DHEA-S measurements if symptoms worsen or fail to improve after 6 months of therapy 1.

  • Address psychological impact of hyperandrogenic symptoms as part of comprehensive care 1.

Common Pitfalls to Avoid

  • Do not use DHEA-S as a first-line diagnostic test—measure total and free testosterone first 1.

  • Do not attribute all elevated DHEA-S to PCOS—always exclude adrenal pathology and non-classic CAH 2, 1.

  • Do not prescribe antiandrogens without contraception due to teratogenic risk 5, 4.

  • Do not overlook metabolic screening—insulin resistance is present in the majority of PCOS patients and influences treatment response 1, 6, 7.
