The metabolic clearance rate of dehydroisoandrosterone sulfate (MCRDS) was determined prospectively in gravidas with and without chronic essential hypertension. In normotensive patients, the MCRDS increased in a linear fashion throughout pregnancy. In patients with chronic essential hypertension the MCRDS also increased progressively, but at higher values than in normotensive subjects. In normotensive gravidas who ultimately developed pregnancy-induced hypertension, the MCRDS increased progressively at a higher level than in gravidas who remained normotensive until approximately 4 weeks prior to the onset of clinical symptoms, at which time the MCRDS slowly decreased. Similarly, in gravidas with chronic hypertension who developed superimposed pregnancy-induced hypertension, the MCRDS increased progressively at higher levels than all groups studied until approximately 4 weeks prior to the onset of hypertension, when a progressive decline in the MCRDS began.
