Mild adrenal 3 beta-hydroxysteroid dehydrogenase deficiency with hyperaldosteronism.

Abstract

The patient was admitted to our hospital at 19 and again at 22-yr of age for hirsutism and hypertension. Her baseline and ACTH-stimulated plasma 17-hydroxy pregnenolone, dehydroepiandrosterone and dehydroepiandrosterone sulfate were increased whereas plasma 17-hydroxy progesterone and androstenedione were normal and responded poorly to ACTH. Plasma deoxycorticosterone, corticosterone and cortisol baseline levels were normal, and they responded normally to ACTH. The plasma aldosterone concentration (PAC) was always high and responded well to ACTH, angiotensin III and furosemide-upright stimulation. However, plasma renin activity (PRA) was normal or slightly high, and responded normally to furosemide-upright stimulation and fluorohydrocortisone suppression. Dexamethasone (2 mg/day) for 1-2 weeks suppressed the androgens, cortisol and corticosterone levels. PRA and PAC were suppressed temporally, but PRA returned to normal and PAC to be a high level after 2 weeks of dexamethasone administration. Blood pressure was also reduced temporally but returned to a high level after 2 weeks of dexamethasone. These results indicate that primary aldosteronism and dexamethasone-suppressible hyperaldosteronism were not likely to be present, and unknown aldosterone stimulating factors which potentiated the action of endogenous angiotensin II or ACTH might be responsible for the hyperaldosteronism in this patient. We conclude that this patient had a mild and non-salt losing 3 beta-HSD deficiency in the zona reticularis with normal fasciculata and high glomerulosa function.
