Conclusion
The lower risk of intrauterine fetal death for those women who received more transfusions throughout pregnancy observed in the current study leads us once more to raise the need for prospective, multicenter, randomized trials to determine whether the potential benefits balance the risks of prophylactic transfusions.
Results
Among 29 newborns, 19 (65.5%) were full-term and 10 pre-term; 24 (82.7%) caesareans and 5 (17.2%) natural births were observed. The mean gestational age at birth and mother`s age were 36.6 weeks (30-40) and 26.7 years (17-39), respectively. No maternal death was observed. The main maternal obstetric and non-obstetric complications were: pre-eclampsia and gestational diabetes, and vaso-occlusive crisis, urinary tract infection and acute chest syndrome, respectively. Twenty-six (47.0%) fetal deaths were observed, 24 being intrauterine fetal (14 early abortions, 10 late abortions and 2 stillbirths). Regarding the red blood cell transfusion history, 40 (72.7%) out of 55 pregnancies received transfusion. Pregnant women who received 6 or more transfusions throughout pregnancy had a significantly lower number of abortions, i.e., no cases of early abortion and only 1 case of late abortion, versus 14 and 9 cases in pregnancies with 0-5 transfusions, respectively. Despite advances in the management of SCD, pregnant women with SCD (particularly those with HbSS) are at a high risk for maternal and fetal complications, even though they are followed in reference centers.
