Effect of ursodeoxycholic acid therapy due to pregnant intrahepatic cholestasis on chemerin and irisin levels.

The purpose of the work was to assess changes in chemerin and irisin levels in women with diagnosed intrahepatic cholestasis of pregnant women treated with ursodeoxycholic acid. The study group consisted of 50 patients with diagnosed and confirmed intrahepatic cholestasis of pregnant women at 24-25 weeks of pregnancy treatment by ursodeoxycholic acid (UDCA). The study also included a group of 40 pregnant women, without concomitant intrahepatic cholestasis of pregnancy (ICP). In the pregnant ICP group, whole blood was collected 4 times: before the first dose of drug, 4 and 8 weeks after the first dose, and day after delivery. It was observed that statistically significant differences in the concentration of irisine occur between the time before starting treatment and the 8-week therapy and 1 day after delivery. The Pearson correlation analysis (r's) showed two statistically significant relationships (p < .05). The first of these can be found between the concentration of irisine and chemerin in the group of nonpregnant women and the second in the group of patients with intrahepatic pregnant cholestasis before the first dose of UDCA. A significant relationship between irisin and chemerin concentrations was confirmed in the group of pregnant ICP patients during UDCA acid therapy and among healthy pregnant women.
