RESUMO
PURPOSE: To investigate first trimester maternal serum pregnancy associated plasma protein A (PAPP-A) multiple of the median (MoM) in cases with intrahepatic cholestasis of pregnancy (ICP). Obstetric complications and relation with PAPP-A MoM were also evaluated. MATERIALS AND METHODS: This was a retrospective case-control study. After exclusions, for each ICP case, two controls with uncomplicated singleton pregnancies were randomly selected. PAPP-A MoM of ICP cases with and without obstetric complications, and the control group were compared with each other. RESULTS: Total incidence of ICP was 0.99 % (138/13988). The study included 113 singleton pregnant women. Rates of gestational diabetes mellitus (GDM), preeclampsia (PE), fetal growth restriction (FGR), preterm labor (PTL), and hypothyroidism in cases with ICP were 21.2%, 7.9%, 10.6%, 18.6%, and 5.3%, respectively. Median PAPP-A MoM were 0.93 in ICP group and 1.10 in control group (p > 0.05). PAPP-A MoM levels were not significantly different either between the ICP group with complicated pregnancies and the control group or between the ICP group without complicated pregnancies and the control group (p >0.05). CONCLUSION: ICP incidence was similar to other European countries. Rates of obstetric complications expecially GDM were higher than expected in general pregnant population. ICP is not considered as pregnancy complications that have low PAPP-A MoM levels.
