Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are pregnant women with sickle cell disease who have been exposed to hydroxyurea during pregnancy or breastfeeding.
✕Probably not a fit
Patients who do not have access to medical records or lack information about hydroxyurea exposure will not benefit from this study.

What this trial studies
This observational study aims to document and analyze the effects of hydroxyurea exposure on women with sickle cell disease (SCD) and their infants during pregnancy and lactation. It will involve chart reviews and surveys to gather data on medical records of pregnant women with SCD who have been exposed to hydroxyurea, including those who experienced miscarriages or stillbirths. The study seeks to clarify the potential risks and outcomes associated with hydroxyurea use in this population, addressing a critical gap in existing knowledge regarding maternal and infant health. By examining both hydroxyurea-exposed and non-exposed pregnancies, the study aims to provide insights into the safety and implications of this treatment during critical periods.
Why it matters
Potential benefit: If successful, this study could provide essential information to improve the management of pregnant women with sickle cell disease and enhance outcomes for both mothers and their babies.
How similar studies have gone: While there is limited data on hydroxyurea exposure during pregnancy, previous studies have documented its benefits in treating sickle cell disease, making this investigation both relevant and necessary.
