Sickle cell disease (SCD) is a group of inherited red blood cell disorders. A healthy red blood cell is round and flexible, allowing it to move easily through blood vessels. In SCD, the red blood cells become hard, sticky, and C-shaped, like a sickle. This can cause the cells to get stuck in small blood vessels, blocking blood flow and leading to pain and other serious health problems.

If you or a loved one has SCD, it’s important to connect with healthcare providers and support groups who understand the disease. You can find more information from organizations like the Sickle Cell Programme and other local and international patient advocacy groups.

With proper medical care and management, many people with SCD can live full and productive lives. It’s crucial for individuals with SCD to:

• Follow their doctor’s treatment plan.
• Maintain a healthy lifestyle, including a balanced diet and regular exercise.
• Stay hydrated to help prevent pain crises.
• Avoid triggers like extreme temperatures and high altitudes.
• Get regular check-ups and screenings.

While there is no universal cure, there are effective treatments to manage symptoms and prevent complications. These include:

• Medications:
  • Hydroxyurea: This is a common and effective medication that helps reduce the frequency of pain crises and the need for blood transfusions.
  • Pain relievers: Medications ranging from over-the-counter pain relievers to prescription opioids are used to manage pain during crises.
  • Antibiotics: Daily penicillin for infants and young children can prevent serious infections.
• Blood transfusions: Transfusions can help manage severe anemia and prevent complications like stroke.

Gene therapy: This is a promising area of research, with clinical trials exploring new ways to correct the genetic defect that causes SCD.

The only known cure for SCD is a bone marrow or stem cell transplant. This is a complex procedure with significant risks, and a suitable donor is often difficult to find. As a result, it is not a suitable treatment option for everyone.

SCD is usually diagnosed through a simple blood test. Many countries now screen all newborns for SCD as part of their standard newborn screening programs. This allows for early diagnosis and treatment, which can help prevent complications. For older children and adults, a blood test can also confirm the diagnosis.

Symptoms of SCD vary from person to person and can change over time. Common symptoms include:

• Anemia: Sickle cells die more quickly than healthy red blood cells, leading to a shortage of red blood cells (anemia), which can cause fatigue.
• Pain crises: This is a hallmark symptom of SCD. Pain occurs when sickle-shaped red blood cells block blood flow in small blood vessels, leading to severe pain in the chest, back, arms, legs, or abdomen.
• Swelling of hands and feet: This is often one of the first signs of SCD in infants and young children.
• Frequent infections: Damage to the spleen, an organ that helps fight infection, can make people with SCD more susceptible to infections.
• Delayed growth or puberty: The shortage of healthy red blood cells can slow growth in children and delay puberty in teens.

Vision problems: Blocked blood vessels to the retina can cause vision damage.

SCD is an inherited genetic disorder. A person is born with it, and it is not contagious. It is passed down from parents to their children. For a child to have SCD, they must inherit two sickle cell genes, one from each parent. If a child inherits a sickle cell gene from one parent and a normal gene from the other, they will have sickle cell trait (SCT). People with SCT usually don’t have symptoms of SCD, but they can still pass the gene on to their children.
