    Abstract:
    The plasma levels of human chorionic somatomammotropin (hCS), estriol (E3), dehydroepiandrosterone sulphate (DHA-S), cortisol and the circadian changes of the two last adrenal hormones were studied in 25 pregnant methadone-addicted women (MA) and 21 pregnant drug-naive controls (C) at different periods of gestation and in 13 non-pregnant women (7 MA and 6 drug-naive). MA pregnant women showed normal plasma levels of hCS both at the second (6.9 +/- 0.1 vs. 7.2 +/- 0.1 micrograms/ml) and third (9.6 +/- 0.2 vs. 9.3 +/- 0.2) trimester, while plasma concentrations of E3 at term were lower than normal (MA: 4.4 +/- 0.8; C: 8.2 +/- 1.0 ng/ml, P less than 0.05). DHA-S plasma levels of MA pregnant women were half the normal values in three trimesters of gestation, while there were no differences in non-pregnant subjects. Circadian variations of cortisol and DHA-S plasma levels were present in both MA and C. The blunted DHA-S but normal cortisol plasma levels found in MA pregnant women indicate that opiate abuse interferes with adrenal function, mainly of the fetus. Due to the scarce availability of adrenal precursors, these data suggest that E3 measurements should not be considered as a useful index of fetal well-being in the presence of opiate addiction.
