OBSTETRICS Intrahepatic Cholestasis of Pregnancy in Women With a Multiple Pregnancy: An Analysis of Risks and Pregnancy Outcomes

Objective: This study was conducted to assess the incidence and perinatal outcomes of multiple pregnancies complicated by intrahepatic cholestasis of pregnancy in an urban population. Methods: We performed a retrospective chart review of all multiple gestation deliveries at our institution between January 2004 and December 2005. Antepartum and delivery data were collected for all patients. Symptoms and treatment were also abstracted for patients in whom intrahepatic cholestasis was diagnosed. We used the Student two-tail t test and Fisher exact test to examine the differences between multiple gestation pregnancies with and without cholestasis of pregnancy. Results: Data were available for 263 multiple pregnancies. The incidence of cholestasis was 4.2 % (11/263), with a mean onset at 29.4 weeks. There were no differences in mean gestational age a
