Objectives: To assess the role of the cerebro-placental ratio (CPR) in predicting adverse fetal outcomes among women with sickle cell disease (SCD).Methods: A prospective cohort study at Korle-Bu Teaching Hospital, Accra, Ghana, between January and June 2016. Pregnant women with SCD at 34 gestational weeks or more underwent weekly fetal umbilical and middle cerebral artery Doppler assessment until delivery. Participants were categorized into two study arms based on CPR (<1.1 or ≥1.1). The primary outcome, a composite of adverse perinatal outcomes including intrauterine growth restriction, stillbirth, low birthweight, and neonatal intensive care unit admission, was compared between groups.Results: Overall, 48 pregnant women with SCD were enrolled, and 5 had a fetus with CPR less than 1.1. Low CPR (<1.1) had a sensitivity and specificity of 29.4% and 100%, respectively, for predicting composite adverse perinatal outcomes. Sensitivity and specificity were, respectively, 100% and 93.5% for predicting stillbirth, and 40.2% and 97.4% for predicting low birthweight. Perinatal outcomes did not differ between the two major sickle cell genotypes (hemoglobin SS and hemoglobin SC).Conclusions: Among women with SCD, CPR less than 1.1 was associated with adverse perinatal outcomes, particularly low birthweight and stillbirth.
