Insights
For children with sickle cell disease (SCD) who have had a stroke, oral hydroxyurea may be an alternative to monthly blood transfusions for preventing future strokes. This approach aims to reduce the risk of recurrent cerebrovascular events.
Area of Science:
- Hematology
- Pediatric Neurology
- Vascular Medicine
Background:
- Sickle cell disease (SCD) is a genetic blood disorder characterized by abnormal hemoglobin, leading to various complications.
- Cerebrovascular accidents (strokes) are a significant concern in pediatric SCD patients, necessitating effective secondary prevention strategies.
Observation:
- A 10-year-old male with hemoglobin SS (SCD) experienced a stroke at age 7.
- Initial management involved transfusions to maintain hemoglobin S levels below 30%.
Findings:
- The family inquired about using oral hydroxyurea as an alternative to regular blood transfusions for stroke prevention.
- Hydroxyurea is a medication known to increase fetal hemoglobin (HbF) levels, which can ameliorate SCD complications.
Implications:
- This highlights the potential for hydroxyurea in the secondary stroke prevention for pediatric SCD patients.
- Exploring non-transfusion-based therapies like hydroxyurea could improve patient quality of life and reduce transfusion-related risks.
Abstract:
A 10-year-old male patient with hemoglobin SS suffered a stroke at 7 years of age and was initially transfused at the time of presentation to lower the hemoglobin S concentration to < 30%. You are asked by the family if their child can be treated with oral hydroxyurea rather than monthly transfusions for the secondary prevention of strokes.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
