[Effect of bromocriptine on the endocrine profile during pregnancy].
In this paper, we revealed the changes in maternal plasma concentration of PRL, HCG, HPL, progesterone (P), estradiol-17 beta (E2), estriol (E3), estetrol (E4) and dehydroepiandrosterone-sulfate (DHEA-S) after the administration of bromocriptine during pregnancy. Blood samples were collected from 23 women with gestation ranging from 7 to 28 weeks. Sixteen patients had therapeutic abortion and other 7 patients had inevitable abortion. PRL, HCG, HPL, P, E2, E3, E4 and DHEA-S were measured by radioimmunoassay. The PRL decreased significantly at 120 and 180 minutes after the administration of bromocriptine in any case. In 4 cases out of 10 cases in early normal pregnancy, plasma E2 level decreased to 50% lower than the basal level, but no significant change of E2 occurred after bromocriptine in early and mid pregnancy. Bromocriptine made no change in HCG, HPL, P, E3, E4 and DHEA-S for any group. Our data suggested that bromocriptine had effect on only plasma PRL level, and this drug or the change of PRL level had no effect on P, estrogen, DHEA-S, HPL and HCG concentration during pregnancy.
