Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy‐specific liver disease and the second most frequent cause of jaundice in pregnancy, but the etiology of it is poorly understood. By collecting blood and fecal samples from 12 healthy pregnant women (CON group) and 32 ICP patients (ICP group) in China, we performed 16s rRNA gene sequencing and analyzed microbial diversity. The results showed a decrease in species richness of the ICP group compared to that in the CON group, with a significant difference in species diversity between the two groups. Differential analysis revealed the following biomarkers: s__unclassified__Megamonas, g__Megamonas, f__Selenomonadaceae, c__Bacilli, and o__Lactobacillales. Importantly, we found a decrease in species richness of Selenomonadaceae at the family level and decreased bacilli at the class level in ICP patients. Correlation network analysis and functional gene prediction were performed accordingly. Our data provided new information linking microbiota and ICP, and are possibly helpful for further exploration of the disease.
