    Abstract:
    OBJECTIVE: Maternal and fetal risk is often high during pregnancy in sickle cell disease. Our objective was to evaluate the benefits of a transfusion program adapted to each pregnant patient, either by red cell transfusion or by automated red cell exchange, in sickle cell patients with a history of serious obstetrical and/or sickling complications. STUDY DESIGN: We managed 18 pregnancies in 14 patients (12 SS, 1 SC, 1 S/b-thalassemia), seven of whom had a history of one or more pregnancies, with severe maternofetal complications in nine out of 10 cases. The other seven patients were pregnant for the first time and were in care because of a history of severe sickling complications. The aim was to achieve a proportion of abnormal hemoglobin (hemoglobin S or S+C) below 50% and a hemoglobin level between 9 and 11 g/dL. The choice between transfusion and red cell exchange was made in the light of the hemoglobin level. Red cell exchange was done using a Fresenius Com. Tec blood cell separator. Patients had red cell exchange in 10 cases, and transfusions in five cases. In three cases, patients had successive transfusions and red cell exchange. RESULTS: No serious maternal complication was observed. No fetal or perinatal death occurred. In one case, delivery was induced at 36 weeks of gestation because of fetal distress and hypotrophy. CONCLUSIONS: Our study suggests that women with severe sickle cell disease, even if they have a serious obstetrical history, can carry their pregnancy to term, without major obstetric complications, through a combination of early management by a multidisciplinary team and a suitable policy of prophylactic transfusion or automated red cell exchange.
