Plasma hormone profile of threatened abortion and its prognosis

Abstract

Hormone levels in patients with threatened abortion were compared with those of women with normal pregnancies to determine the relationship between these hormone patterns and patient prognoses. Plasma progesterone, plasma unconjugated estradiol-17beta (estradiol), and plasma human chorionic somato-mammotropin (HCS) were measured serially in 27 patients with threatened abortion. Twelve of these patients were able to continue their pregnancies, and 15 patients aborted. Of the 3 indices tested, 2 (plasma estradiol and HCS levels) showed marked differences in women who were able to continue their pregnancies and women whose pregnancies ended in abortions; moreover, these findings indicated that these 2 levels could be used as indices for the evaluation of a pregnant patient's prognosis.
