Trial DHEA Replacement in Women with PAI and Specific Symptoms
STEP 1 — Gather Information
Confirm PAI diagnosis, review current glucocorticoid (e.g., hydrocortisone 15–25 mg/day) and mineralocorticoid (fludrocortisone 50–100 µg/day) doses, assess for clinical signs of over- or under-replacement (weight, BP, electrolytes), and document presence of low libido, depressive symptoms, and/or low energy levels.
STEP 2 — Rule In / Rule Out
Determine whether symptoms persist despite optimized steroid replacement; if yes, proceed to DHEA trial consideration, otherwise evaluate for other causes of fatigue or low libido (e.g., thyroid dysfunction, depression, anemia).
STEP 3 — Classify or Stratify
Classify the patient as a candidate for a DHEA replacement trial if she is a woman with PAI, has low libido, depressive symptoms, and/or low energy levels, and is on otherwise optimized glucocorticoid and mineralocorticoid therapy; proceed to step 4 to initiate the trial.
STEP 4 — Decide
Initiate a trial of DHEA 25–50 mg orally each morning, measure morning serum DHEAS before each dose aiming for the mid-normal range, and schedule clinical reassessment of libido, mood, and energy after 6 months; if sustained benefit is reported, continue therapy, otherwise discontinue DHEA.
Clinical Guardrails / Mimics / Pitfalls
Do not use DHEA as first-line therapy before optimizing glucocorticoid and mineralocorticoid replacement; avoid in men, pregnancy, or hormone-sensitive malignancies; monitor for androgenic side effects (acne, hirsutism, voice changes); do not rely solely on DHEAS levels without clinical response; DHEA is not routinely recommended due to insufficient evidence for broad use.
Concrete Clinical Example
A 48-year-old woman with autoimmune PAI on hydrocortisone 20 mg daily and fludrocortisone 100 µg daily reports persistent low libido and fatigue despite stable weight, normal BP, and normal electrolytes; after confirming optimized replacement, a trial of DHEA 25 mg each morning is started; at 6‑month follow‑up she notes improved energy and libido, DHEAS is mid‑normal, and therapy is continued.
