The effect of intrahepatic cholestasis of pregnancy and ursodeoxycholic acid treatment on Doppler parameters of fetal and maternal circulation.

ABSTRACT

OBJECTIVES: We aimed to evaluate feto-maternal blood flow parameters using Doppler ultrasonography (USG) in pregnant women with intrahepatic cholestasis of pregnancy (ICP) and the effect of ursodeoxycholic acid (UDCA) treatment on these parameters. MATERIAL AND METHODS: This prospective cohort study was performed at Dr. Sami Ulus Women's and Children's Health Teaching and Research Hospital, in Turkey between September 2022 and February 2023. Sixty pregnant women, 30 with ICP disease and 30 healthy women were included in the study. Obstetric Doppler parameters were measured by USG at diagnosis and after 48 hours of UDCA treatment for the ICP group. RESULTS: The obstetric Doppler parameters did not significantly differ in the ICP group and the healthy control group. The Doppler findings were similar after UDCA treatment in the ICP group. Gestational week at delivery and birth weight were lower in the ICP group in our study. CONCLUSIONS: We demonstrated that pregnant women with ICP had similar obstetric Doppler parameters when compared with healthy pregnant women and that the UDCA agent used for treatment of ICP disease did not affect these parameters.
