Due to the effects of Autotaxin on the physiology of pregnancy, we aimed to investigate Autotaxin activity in patients with intrahepatic cholestasis of pregnancy. Patients and methods: Sixty-nine patients diagnosed with intrahepatic cholestasis of pregnancy and 20 healthy pregnant women were enrolled in the study. Fasting serum bile acid, pruritus intensity, serum parameters, gestational week of the patients at the time of diagnosis were recorded, and birth week and birth weight were monitored. Autotaxin serum level was measured enzymatically. Results: The mean serum bile acid level (n = 69; 38.74 ± 35.92 ?mol/L) in patients with intrahepatic cholestasis of pregnancy (n = 69) was detected to be higher than healthy pregnant women (n = 20; 5.05 ± 1.88 ?mol/L) (p < 0.001). Weak correlation was detected between serum bile acid level and itch intensity (p = 0.014, r = 0.295), while no relation was detected between Autotaxin and itch intensity (p = 0.446, r = 0.09). Although mean Autotaxin (intrahepatic cholestasis of pregnancy: 678.10 ± 424.42 pg/mL, control: 535.16 ± 256.47 pg/mL) levels were high in patients with intrahepatic cholestasis of pregnancy, it was not statistically significant (p = 0.157). Conclusion: In our study, we observed that the serum Autotaxin level did not make a significant difference in patients with intrahepatic cholestasis of pregnancy compared to healthy pregnant women. These findings suggest that larger clinical studies are required to reveal the physio-pathological effects of Autotaxin on pregnancy. © 2020 Elsevier España, S.L.U.en10.1016/j.gastrohep.2020.08.001info:eu-repo/semantics/closedAccessAutotaxinIntrahepatic cholestasisPregnancyPruritusalanine aminotransferaseaspartate aminotransferaseautotaxinbile acidbilirubinalkylglycerophosphoethanolamine phosphodiesterasephosphodiesteraseadultalanine aminotransferase blood levelArticleaspartate aminotransferase blood levelbile acid blood levelbilirubin blood levelbirth weightcontrolled studydisease associationdisease severityenzyme activityenzyme blood levelfemalegestational agehumanintrahepatic cholestasisintrahepatic cholestasis of pregnancymajor clinical studypregnancy complicationpregnant womanpruritusbloodcomplicationintrahepatic cholestasispregnancypregnancy complicationprospective studypruritusAdultCholestasis, IntrahepaticFemaleHumansPhosphoric Diester HydrolasesPregnancyPregnancy ComplicationsProspective StudiesPruritusArticle44296102Q2WOS:0006296427000022-s2.0-8509214773433010963Q3
