Treatment of Androstenedione Suppression
For patients with androstenedione suppression, dehydroepiandrosterone (DHEA) supplementation at a dose of 10-50 mg daily (typically 25 mg) is the recommended treatment, guided by serum DHEA sulfate, androstenedione, and testosterone levels. 1
Understanding Androstenedione Suppression
Androstenedione is an important adrenal androgen that serves as a precursor to both testosterone and estradiol. Suppression of androstenedione can occur in various conditions, most notably in:
- Primary adrenal insufficiency (PAI) where adrenal androgen secretion is deficient 1
- During androgen deprivation therapy (ADT) for prostate cancer 1
- As a side effect of certain medications
Treatment Approach
First-line Treatment: DHEA Supplementation
- Dosage: 10-50 mg oral DHEA tablets daily, often starting with 25 mg as a single daily dose 1
- Monitoring: Treatment should be guided by morning measurements of:
- Serum DHEA sulfate (DHEAS)
- Androstenedione levels
- Testosterone levels 1
- Goal: Maintain these hormone levels within the normal range when measured in the morning prior to DHEA ingestion 1
Patient Selection for DHEA Therapy
DHEA replacement should be considered for:
- Female patients with persistent lack of libido despite optimized other hormone replacement 1
- Patients with low energy levels 1
- Patients with laboratory-confirmed androstenedione suppression 1
Treatment Duration and Assessment
- A pragmatic approach is to offer a 6-month trial of DHEA replacement 1
- Continue therapy if clinically effective (improvement in symptoms) 1
- Discontinue if no benefit is observed after adequate trial period
Special Considerations
Caution in Treatment
- Long-term effects of DHEA or testosterone replacement therapy in patients with primary adrenal insufficiency are not well established 1
- Use DHEA supplementation with caution, particularly in patients with hormone-sensitive conditions 1
Gender-Specific Considerations
- DHEA supplementation is particularly important for female patients with adrenal insufficiency, as they may experience severe androgen deficiency 1
- In men, the clinical benefits may be less pronounced as they have additional sources of androgens
Monitoring During Treatment
- Regular assessment of serum DHEAS, androstenedione, and testosterone levels 1
- Clinical evaluation of symptom improvement (energy, libido, general well-being)
- Monitoring for potential adverse effects
Alternative Approaches
In cases where DHEA is contraindicated or unavailable, other options may include:
- Low-dose testosterone therapy in women (under specialist supervision)
- Lifestyle modifications to support adrenal function
- Treatment of underlying causes of androstenedione suppression
Common Pitfalls to Avoid
- Failure to monitor hormone levels during treatment
- Using excessive doses of DHEA which may lead to androgenic side effects
- Not providing an adequate trial period before determining efficacy
- Overlooking the underlying cause of androstenedione suppression
Remember that while DHEA supplementation is the recommended approach for androstenedione suppression, the evidence for clinical benefit from large studies remains limited 1, necessitating careful patient selection and monitoring.
