Adrenal Hormones and Disorders

Pathological and biochemical observations are presented in two cases of virilizing adrenal hyperplasia: one of the sodium-losing type and the other of the hypertensive type. Examination of the kidneys revealed hypertrophy of the juxtaglomerular cells in the case exhibiting excessive sodium loss. The adrenal cortex showed hypertrophy of the zona glomerulosa. It is hypothesized that the chronic state of sodium loss caused changes in the intravascular compartment which led to compensatory activity of the juxtaglomerular cells with resultant stimulation of the zona glomerulosa. Examination of the hypertensive case (known to involve a different enzyme deficit) showed hypertrophy of the zona glomerulosa without hypertrophy of the juxtaglomerular cells. The intrinsic overproduction of sodium-retaining steroids associated with the genetic defect in this clinical form could account for both the hypertension and the absence of hypertrophy of the juxtaglomerular apparatus.
