About this trial

Aplastic anemia (AA) is a rare haematologic disorder characterized by bone marrow failure and pancytopenia. Its occurrence during pregnancy is exceedingly rare but poses significant risks, including maternal hemorrhage, infections, and perinatal complications such as preterm birth and fetal growth restriction. Consequently, pregnancy with AA is highly perilous for both mothers and infants. Early management is critical to ensure the health of both the mother and the baby. However, there are currently no predictive tools available to assess adverse outcomes in pregnant women with AA. Our center plans to conduct a multicenter, combined retrospective and prospective cohort study.

Number of participants with Adverse pregnancy outcomes

Incident of adverse pregnany outcomes include at least one of the conditions as follows: placental abruption (ultrasound to detect a retroplacental hematoma), amniotic fluid embolism (elevated fetal squamous cells, vernix, or meconium in maternal blood; prolonged PT, APTT, low fibrinogen, and elevated D-dimers), postpartum hemorrhage (≥500 mL blood loss within 24 hours of vaginal delivery or ≥1000 mL after cesarean delivery), postpartum infection (fever, leukocytosis, etc), maternal mortality, stillbirths (fetal death occurring at ≥20 weeks of gestation), preterm birth (delivery at \<37 weeks of gestation), low birthweight ( a newborn with birth weight \<2500 g), fetal growth restriction (a fetus with estimated fetal weight or abdominal circumference \<10th percentile for gestational age), neonatal intensive care unit admission, or neonatal mortality (death of a live-born infant within the first 28 days of life).
