Abstract
OBJECTIVE: Women with sickle cell disease (SCD) have adverse maternal and infant outcomes. Our aim was to determine whether the outcomes of SCD mothers and their infants differed from African or Caribbean women not affected by SCD and whether there were differences between SCD individuals with the haemoglobin SS (HbSS) or haemoglobin SC (HbSC) genotypes. Furthermore, we wished to determine if any differences related to deprivation. DESIGN: A matched cohort study. SETTING: Tertiary perinatal centre in London PATIENTS: 4964 African or Caribbean women without SCD and 148 with SCD. MAIN OUTCOME MEASURES: Mode of delivery, maternal exchange transfusion, birthweight, neonatal unit admission, neonatal death and deprivation indices RESULTS: SCD women were more likely to be delivered by caesarean section (p<0.001) and had babies of lower birthweight (p<0.001). Their infants were no more likely to be admitted to neonatal intensive care unit or suffer a neonatal death. There were no significant differences between the SCD women and those without SCD in their deprivation index or deprivation decile. The women with the HbSS genotype compared to those with the HbSC genotype were more anaemic (p<0.02), required more exchange transfusions (p<0.001) and were more likely to be delivered by caesarean section (p=0.008). The infant outcomes did not differ significantly between the genotypes. CONCLUSIONS: Although, the SCD women, particularly those with the HbSS genotype, had greater morbidity, infant morbidity, and mortality was similar in mothers with the HbSS or HbSC genotypes and those without SCD.
