|January 1, 1976
Summary
Periodic blood transfusions can prevent worsening neurologic damage in children with sickle cell anemia (SCA). This treatment shows promise in reducing recurrent central nervous system (CNS) infarction and improving neurological function.
Area of Science:
- Hematology
- Neurology
- Pediatrics
Background:
- Central nervous system (CNS) infarction is a severe complication of sickle cell anemia (SCA).
- Recurrent CNS infarction in SCA often leads to permanent neurological deficits.
- Preventing these recurrences is crucial for managing SCA patients.
Purpose of the Study:
- To evaluate the efficacy of a periodic transfusion program in preventing recurrent CNS infarction in children with SCA.
- To assess the impact of transfusions on existing neurologic abnormalities.
Main Methods:
- A periodic transfusion program involving buffy-coat poor transfusions every 3 weeks was implemented.
- Twenty-one children with SCA were enrolled in the program.
- Follow-up periods ranged from 9 months to over 5 years.
Main Results:
- None of the 15 children on the program for at least 9 months experienced progression of neurologic abnormalities.
- Several children demonstrated definite improvement in neurologic function.
- One child with irregular attendance experienced recurrent CNS infarction.
- The primary complication noted was a single instance of serum hepatitis.
Conclusions:
- Periodic transfusion programs appear effective in preventing the progression of neurologic abnormalities associated with recurrent CNS infarction in sickle cell anemia.
- While transfusion programs carry risks, they offer a viable strategy for managing neurological complications in pediatric SCA patients.
