What Is Sickle Cell Disease?
Sickle cell disease (SCD) is an inherited blood disorder that changes the shape and function of red blood cells, making it harder for oxygen to travel through the body.
These sickle-shaped cells can block blood flow, leading to severe pain episodes, anemia, infections, stroke risk, and long-term organ damage. Understanding how SCD develops, how it affects daily life, and what treatment options are available can help patients, families, and caregivers make informed decisions and better manage the condition.
Learn about the causes of SCD, common complications, specialized care, and the latest advances in treatment and gene therapy.
Penicillin Prophylaxis in Sickle Cell Disease
Protecting Children From Serious Infections
Children with sickle cell disease are at much higher risk for serious infections because the disease can damage the spleen and weaken the body’s ability to fight bacteria.
Daily penicillin prophylaxis, started early in infancy, is one of the most effective ways to reduce the risk of life-threatening infections such as pneumonia, meningitis, and sepsis.
Learn why preventive antibiotics are recommended, which children need them most, how long treatment should continue, and why vaccines, fever monitoring, and specialized sickle cell care remain essential parts of keeping children healthy and protected.
Hydroxyurea for Sickle Cell Disease
A Treatment That Helps Prevent Pain and Protect Health
Hydroxyurea is one of the most important and widely used treatments for sickle cell disease. This daily medication helps the body produce more fetal hemoglobin, which keeps red blood cells healthier and reduces sickling that can block blood flow. For many children and adults with SCD, hydroxyurea can lower the number of painful crises, reduce hospital visits and transfusions, and help protect organs over time.
Learn how hydroxyurea works, who may benefit from treatment, what side effects to watch for, and why regular monitoring with a specialized sickle cell care team is essential for safe and effective treatment.
Transcranial Doppler (TCD) Screening
Preventing Stroke in Children With Sickle Cell Disease
Transcranial Doppler (TCD) screening is a safe, painless ultrasound test that helps identify stroke risk in children with sickle cell disease before symptoms appear. Because sickle-shaped red blood cells can damage and narrow blood vessels in the brain, children with HbSS or HbSβ⁰-thalassemia are at increased risk for stroke during childhood.
Regular TCD screening allows healthcare teams to detect dangerous changes in blood flow early and begin preventive treatments such as transfusion therapy that can dramatically reduce stroke risk.
Learn how TCD testing works, when children should be screened, and why early detection plays a critical role in protecting brain health and long-term development.
