Silent cerebral infarct (stroke) is the most common cause of severe cognitive impairments and related neurological functions in children with sickle cell anemia. Currently there exists no systemic strategy to identify or treat children with silent strokes.
The primary aim of this trial is to determine the effectiveness of blood transfusion therapy for the prevention of silent strokes in children with sickle cell anemia. This trial will also determine if blood transfusion therapy will prevent further cerebral injury and if the measured benefits of the therapy outweigh the risks associated with it.
Participants in this multi-center trial will be randomly assigned to one of 2 groups-the blood transfusion group or the observation group. Those in the blood transfusion group will receive at least monthly blood transfusion therapy. All participants will have history and physical examinations every 3 months, and magnetic resonance imaging (MRI) at the beginning of their entry into the study and at study exit.
Advances in the understanding and treatment of silent strokes will likely lead to a decrease in the burden associated with cerebral injury in children with sickle cell anemia and change the standard care for these children.

To conduct a prospective study aimed at the early detection and treatment of cerebral vascular disease prior to irreversible brain injury in young children with sickle cell anemia (SCA).
This study will summarized the clinical and laboratory data and the outcome of all the patients suffering from Sickle Cell Anemia (Including Sickle cell thalassemia) admitted to the pediat...
Bearers of the sickle cell allele (S) are currently eligible for blood donations in Belgium. As blood donors are not tested for this allele, their heterozygous status is unknown. However, ...
Chronic transfusion therapy with the goal of maintaining a hemoglobin (Hb) S
Sickle cell disease (SCD) is a life-threatening chronic condition primarily caused by genetic mutation. The disease is characterized by intermittent vaso-occlusive events and chronic hemolytic anemia....
Sickle cell disease affects more than 100,000 individuals in the United States, among whom disease severity varies considerably. One factor that influences disease severity is the sickle cell disease ...

Prevention of red blood cell (RBC) alloimmunization in patients with sickle cell disease (SCD) focuses on phenotypic RBC matching. We assessed alloimmunization among transfused patients with SCD after...
An abnormal hemoglobin resulting from the substitution of valine for glutamic acid at position 6 of the beta chain of the globin moiety. The heterozygous state results in sickle cell trait, the homozygous in sickle cell anemia.
One of the sickle cell disorders characterized by the presence of both hemoglobin S and hemoglobin C. It is similar to, but less severe than sickle cell anemia.
Repetitive withdrawal of small amounts of blood and replacement with donor blood until a large proportion of the blood volume has been exchanged. Used in treatment of fetal erythroblastosis, hepatic coma, sickle cell anemia, disseminated intravascular coagulation, septicemia, burns, thrombotic thrombopenic purpura, and fulminant malaria.
A disease characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for hemoglobin S.
An acute purulent infection of the meninges and subarachnoid space caused by Streptococcus pneumoniae, most prevalent in children and adults over the age of 60. This illness may be associated with OTITIS MEDIA; MASTOIDITIS; SINUSITIS; RESPIRATORY TRACT INFECTIONS; sickle cell disease (ANEMIA, SICKLE CELL); skull fractures; and other disorders. Clinical manifestations include FEVER; HEADACHE; neck stiffness; and somnolence followed by SEIZURES; focal neurologic deficits (notably DEAFNESS); and COMA.
