TRAINING and EDUCATION Patient Education THE PEDIATRIC PATIENT LIVING WITH SICKLE CELL DISEASE Sickle cell disease (SCD) is the most common genetic disorder in the United States, with about 100,000 American who have the disease and another 2 million who carry the trait. As people live with SCD for years, management of this disease and healthy living are important components of care, particularly for the pediatric population. Read below for more information about the diagnosis, treatment, and prognosis of SCD in pediatric patients. This “Patient Education” tear sheet was produced in collaboration with the Children’s Sickle Cell Foundation, Inc. (cscfkids.org). What Is Sickle Cell Disease? How Is Sickle Cell Disease Diagnosed? SCD is a group of inherited red blood cell disorders. Normal red blood cells are soft, round, and able to move through small blood vessels (veins and arteries) easily in the body to deliver oxygen. A person with SCD has red blood cells that, under certain conditions, become hard, sticky, and pointed. When they go through the blood tube, they clog the flow and break apart. This can cause pain, organ damage, and a low blood count. SCD occurs when a person inherits two abnormal hemoglobin genes from his or her parents. A person is born with abnormal “sickle hemoglobin,” and it is present for life. Babies of all races should be screened for sickle cell hemoglobin at birth. A simple blood test, called the hemoglobin electrophoresis test, can be conducted to identify if a child is a carrier of the sickle cell trait or has the disease. Every state and the District of Columbia perform the sickle cell test at birth to help get babies born with SCD into care as soon as possible. Other types of traits that may be identified on the test results include: What Is Sickle Cell Trait? Abnormal hemoglobin is inherited from parents who may be carriers of the sickle cell trait (SCT) or who have SCD. If an individual only inherits one sickle gene, it is SCT, while those who inherit two sickle cell genes have SCD. SCT is not a mild form of SCD. People with SCT usually do not have any of the symptoms of SCD and live a normal life. • hemoglobin S trait • hemoglobin C trait • hemoglobin E trait • hemoglobin Barts, which indicates an alpha thalassemia trait • beta thalassemia trait What Are the Complications Associated With Sickle Cell Disease? Complications from the sickled cells blocking blood flow and breaking apart include: • pain • stroke • increased risk of infection • leg ulcers • bone damage • yellow eyes or jaundice • early gallstones • lung blockage • kidney damage and loss of body water in urine Cut out and give to a patient • eye damage • low red blood cell counts (anemia) • delayed growth ASHClinicalNews.org ASH Clinical News 55
