A Sickle Cell Hero is a special blood donor that holds a unique power to help sickle cell patients. ... While a blood donor from any ethnicity can be a match, the best possible match for African Americans with sickle cell is for them to receive blood from African American donors or those of African ancestry.

A sickle cell crisis is pain that can begin suddenly and last several hours to several days. It happens when sickled red blood cells block small blood vessels that carry blood to your bones. You might have pain in your back, knees, legs, arms, chest or stomach. The pain can be throbbing, sharp, dull or stabbing.

Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin).

Treatment. Management of sickle cell anemia is usually aimed at avoiding pain episodes, relieving symptoms and preventing complications. Treatments might include medications and blood transfusions. For some children and teenagers, a stem cell transplant might cure the disease.

Prevention of sickle cell disease symptoms One of the best things you can do to prevent sickle cell symptoms is to stay hydrated. Download our hydration fact sheet below. Avoid extremely hot or cold temperatures. Avoid places or situations with low oxygen, such as high altitudes.

A blood test can check for the defective form of hemoglobin that underlies sickle cell anemia. In the United States, this blood test is part of routine newborn screening. But older children and adults can be tested, too. In adults, a blood sample is drawn from a vein in the arm.

Sickle cells can damage your spleen, the organ that helps fight germs as part of your immune system. That can make you more likely to get pneumonia and other infections. SOURCES: Mayo Clinic: "Sickle Cell Anemia: Symptoms and Causes,” “Sickle Cell Anemia: Diagnosis and Treatment."

Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disorder have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.

With SCD, the hemoglobin in red blood cells is abnormal. This damages the red blood cells. SCD prevents the hemoglobin in red blood cells from carrying oxygen to all parts of the body. Sickle cells clump together, blocking small blood vessels and causing painful and damaging problems.

You may need a blood transfusion if you have anemia, sickle cell disease, a bleeding disorder such as hemophilia, or cancer. For people in critical condition, blood transfusions can be lifesaving. Four types of blood products may be given through blood transfusions: whole blood, red blood cells, platelets, and plasma.

In sickle cell anemia, blood is also chronically low in oxygen. This lack of oxygen-rich blood can damage nerves and organs, including your kidneys, liver and spleen, and can be fatal. Blindness. Sickle cells can block tiny blood vessels that supply your eyes.

These sickle cells can block blood flow in small blood vessels of the body. When blood flow is blocked in vessels that supply bone, the bone does not get enough oxygen and the bone tissue may die.

Scientists are studying gene therapy as a treatment for sickle cell anemia. One day, it's hoped that doctors can stop the disease by changing or replacing the abnormal gene that causes it. But even without a cure, people with sickle cell disease can lead fairly normal lives if they follow their treatment plan.
