Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disease in pregnancy. Although it was shown that multiple pregnancy and hormone therapies increase the risk of ICP, there is limited information that compared spontaneous fertilization and in vitro fertilization (IVF) from the aspect of developing ICP. In our study, we investigated the potential relationship between ICP and IVF/spontaneous pregnancy.
Materials and methods
We reviewed the records (between June 2007 and December 2014) of pregnancies with ICP who were referred to gastroenterology clinics in three different hospitals. Fifty-nine pregnancies (43 spontaneous fertilization, 16 IVF) with ICP were analyzed from the aspect of age, fertilization type, multiple/singleton pregnancy, delivery week, and biochemical results.
Results
We found that serum bile acid levels were higher in the IVF group than the spontaneous fertilization group (32.8 ± 20 vs 19.6 ± 19 μmol/L; p < 0.05). There was a significant inverse correlation between serum bile acid levels and gestational age (r = −0.42, p < 0.01) in the whole group. There was no difference between IVF and spontaneous fertilization groups in term of age, onset time of symptoms, serum alanine aminotransferase (ALT), alkaline phosphatase (ALP), total and direct bilirubin levels, prothrombin time (PT), international normalized ratio (INR), and platelet count.
Conclusion
Our results suggest that the serum bile acid levels are higher in IVF than in spontaneous pregnancies with ICP, but its clinical implications are not clear. Further prospective studies with large number of ICP cases are needed to clarify the effect of IVF on ICP.
