Summary
This study identifies a mild 3 beta-hydroxysteroid dehydrogenase (3 beta-HSD) deficiency in the zona reticularis, leading to hirsutism and hypertension. The findings suggest unknown factors contribute to hyperaldosteronism in this patient.
Area of Science:
- Endocrinology
- Steroidogenesis
- Metabolic Disorders
Background:
- Hirsutism and hypertension in a patient prompted investigation into adrenal steroidogenesis.
- Previous studies highlight the complexity of adrenal enzyme deficiencies.
Observation:
- Elevated 17-hydroxy pregnenolone, dehydroepiandrosterone, and dehydroepiandrosterone sulfate with normal 17-hydroxy progesterone and androstenedione.
- Persistently high plasma aldosterone concentration (PAC) unresponsive to standard suppression tests.
- Dexamethasone temporarily suppressed androgens and aldosterone but PAC remained high.
Findings:
- The patient presents with a mild, non-salt-losing 3 beta-HSD deficiency specifically in the zona reticularis.
- Normal adrenal fasciculata function and heightened glomerulosa function were observed.
- Results exclude primary aldosteronism and dexamethasone-suppressible hyperaldosteronism, suggesting novel aldosterone-stimulating factors.
Implications:
- This case expands the understanding of 3 beta-HSD deficiency spectrum and its clinical manifestations.
- Identifies potential novel mechanisms driving hyperaldosteronism.
- Highlights the importance of comprehensive steroid profiling in complex endocrine disorders.
