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 at delivery, preterm delivery rate, meconium histiocytosis, incidence of preeclampsia, or incidence of postpartum hemorrhage between women with and those without cholestasis. There were no intrauterine fetal deaths in the cholestasis group.
CONCLUSION: Women with multiple gestations complicated by cholestasis of pregnancy do not have increased adverse perinatal outcomes. The absence of unexplained fetal demise may be a result of routine delivery before 40 weeks' gestation in multiple pregnancies.
