New mineralocorticoids and adrenocorticosteroids in hypertension.
Alterations in steroidogenesis have been demonstrated in experimental and human hypertension. It is highly likely that increased secretion of the nonaldosterone mineralocorticoid deoxycorticosterone (DOC) and 18-hydroxy-11-deoxycorticosterone (18-OH-DOC) may initiate or perpetuate hypertension, or both. It is possible that 16 beta-hydroxydehydroeplandrosterone (16beta-OH-DHEA) directly induces the hypertensive process in animals. The significance of the findings of increased secretion of 16 alpha, 18-dihydroxy-11-deoxycorticosterone (16alpha, 18-diOH-DOC) and dehydroepiandrosterone sulfate (DHEA-S) cannot now be appreciated. Neither has been examined experimentally for its ability to induce hypertension, and the former compound is not a mineralocorticoid. It does possess the curious property of increasing mineralocorticoid activity of other steroids, by altering either their metabolism or mode of action. Variations in the mineralocorticoid hypertensive syndrome or, more aptly, the steroid hypertensive syndrome could account for the hypertension in a substantial portion of patients with reduced plasma renin activity.
