Outcome of pregnancies among women with sickle cell disease.

PURPOSE

To evaluate the outcome of pregnancies among women affected by sickle cell disease (SCD).

MATERIAL AND METHODS

This retrospective comparative cohort study was carried out between 1 January 2014 and 31 December 2018. The files of pregnant women with and without SCD were analyzed. The main variables recorded included parity, diseases that occurred during pregnancy, maternal and gestational ages at delivery, mode of delivery, birthweight and Apgar score. Data were analyzed using SPSS 21.0. Fisher exact test and the -test was used for comparison.  < .05 was considered statistically significant.

RESULTS

Our frequency of delivery of women with SCD was 0.1% (35/34,895). Significant complications associated with SCD were maternal anemia (RR = 17.00, 95%CI = 5.35-53.99), intra-uterine fetal demise (RR = 12.00, 95%CI = 1.39-103.22), low birthweight (RR = 2.52, 95%CI = 1.50-4.25), neonatal asphyxia (RR = 7.70, 95%CI = 2.57-22.99), transfer of newborn to the neonatal intensive care unit (RR = 3.42, 95%CI = 1.94-6.03), early neonatal death (RR = 4.56, 95%CI = 1.09-19.10), and maternal postpartum severe anemia (RR = 4.50, 95%CI = 1.36-14.87).

CONCLUSIONS

Pregnancies amongst women with SCD are still associated with increased risk of maternal anemia as well as perinatal morbidity and mortality despite frequent blood transfusion. Therefore, new strategies should be explored to improve such pregnancies.
