    Summary

    Sickle cell disease complications during pregnancy, particularly in Hb S-beta-thalassaemia, include severe anemia and crises. Management focuses on preventing anemia and treating painful episodes to improve maternal and fetal outcomes.

    Area of Science:

    • Hematology
    • Obstetrics
    • Genetics

    Background:

    • Sickle cell disease encompasses S-homozygotes, SC heterozygotes, and S-beta-thalassaemia heterozygotes.
    • While clinical features are similar, pregnancy complications vary in severity among these genotypes.

    Purpose of the Study:

    • To compare the risks and management of sickle cell disease complications during pregnancy across different genotypes.
    • To highlight Hb S-beta-thalassaemia as the most dangerous form regarding maternal mortality.

    Main Methods:

    • Review of clinical features and complications associated with sickle cell disease in pregnancy.
    • Analysis of mortality causes and treatment strategies for anemia and painful crises.

    Main Results:

    • Hb S-beta-thalassaemia presents the highest risk during pregnancy, with mortality linked to severe anemia, sequestration crises, infections, painful episodes, and fat embolism.
    • S-homozygotes face increased risks of operative delivery due to pelvic contraction and higher rates of abortion and perinatal mortality.
    • Intrauterine growth retardation is observed in survivors due to persistent maternal anemia.

    Conclusions:

    • Effective management of anemia with folic acid and antimalarials is crucial.
    • Blood transfusions should be reserved for severe anemia or significant blood loss.
    • Painful crises require analgesics, antibiotics, and potentially heparin; operative delivery may be necessary for S-homozygotes.
