ABSTRACT
OBJECTIVE: Is treatment of early pregnancy failure (EPF) with sequential use of mifepristone and misoprostol more effective than treatment with misoprostol alone? STUDY DESIGN: In a retrospective cohort study at the Department of Obstetrics and Gynaecology of the Radboud University Medical Centre, 301 women with early pregnancy failure receiving medical treatment between January 2008 and March 2013 were included. Of these, 199 women were pre-treated with 200mg mifepristone (orally) followed by 2 consecutive doses of 800mcg misoprostol (vaginally) and 102 women were treated with 2 consecutive doses of 800mcg misoprostol (vaginally) alone. RESULTS: Complete expulsion was achieved in 66.8% of the women treated with a sequential combination of mifepristone and misoprostol versus 54.9% of the women treated with misoprostol alone. The difference in rates of complete expulsion was 11.9% (P<0.05; 95% CI 0.3-23.6%). CONCLUSIONS: Medical treatment of early pregnancy failure with a sequential combination of mifepristone and misoprostol was more effective than treatment with misoprostol alone. Our findings will have to be confirmed by a large prospective multicentre double blinded-randomized trial.
