Impaired fetal adrenal function in intrahepatic cholestasis of pregnancy.

Wang C, Chen X, Zhou SF, Li X - Med. Sci. Monit. (2011)

Bottom Line: In women with ICP, the fetal serum cortisol and DHEAS levels were significantly higher than those in women with normal pregnancy, after correcting the impact of gestational age at delivery.The relationship between fetal cortisol and maternal cholic acid levels was bidirectional; the fetal cortisol tended to increase in mild ICP, while it decreased in severe ICP.In pregnant rats with estrogen-induced cholestasis, the fetal cortisol level was significantly lower in the group with oxytocin injection, compared with the group without oxytocin injection (191.92±18.86 vs. 272.71±31.83 ng/ml, P<0.05).

ABSTRACT

Background: Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-associated liver disease of unknown etiology. The aim of this study was to investigate the change in maternal and fetal adrenal function in clinical and experimental ICP.

Material/methods: The maternal and fetal serum levels of cortisol and dehydroepiandrosterone sulfate (DHEAS) were determined in 14 women with ICP and in pregnant rats with estrogen-induced intrahepatic cholestasis.

Results: In women with ICP, the fetal serum cortisol and DHEAS levels were significantly higher than those in women with normal pregnancy, after correcting the impact of gestational age at delivery. The relationship between fetal cortisol and maternal cholic acid levels was bidirectional; the fetal cortisol tended to increase in mild ICP, while it decreased in severe ICP. In pregnant rats with estrogen-induced cholestasis, the fetal cortisol level was significantly lower in the group with oxytocin injection, compared with the group without oxytocin injection (191.92±18.86 vs. 272.71±31.83 ng/ml, P<0.05). In contrast, the fetal cortisol concentration was increased after oxytocin injection in normal control rats.

Conclusions: The data indicate that fetal stress-responsive system is stimulated in mild ICP, but it is suppressed in severe ICP, which might contribute to the occurrence of unpredictable sudden fetal death. Further studies are warranted to explore the role of impaired fetal adrenal function in the pathogenesis of ICP and the clinical implications.

f1-medscimonit-17-5-cr265: The relationship between maternal cholic acid and fetal adrenal steroid hormone levels. (A) fetal cortisol level; (B) fetal DHEAS level.

Mentions: Interestingly, we observed a bidirectional relationship between fetal serum cortisol and maternal serum cholic acid levels (Figure 1A). Fetal serum cortisol level increased with the elevation of maternal cholic acid level when maternal cholic acid was <2000 μg/dl. However, fetal serum cortisol level decreased with the elevation of maternal cholic acid level when maternal cholic acid was >2000 μg/dl. A similar relationship was also found between fetal serum DHEAS level and maternal cholic acid level (Figure 1B).
