About Blood Disorders
Blood disorders are diseases of the blood including:
  • red blood cells, which carry oxygen to the body’s tissues
  • white blood cells, which help your child’s body to fight infections
  • platelets, which work to help your child’s blood clot properly
  • clotting factors, proteins found in blood that help stop bleeding after a cut or surgery
Types of Red Blood Diseases We Treat
  • Iron-deficiency anemia: low iron levels that lead to decreased hemoglobin, which helps carry oxygen through the blood to all parts of the body 
  • G6PD deficiency (also called RBC enzyme abnormalities): an inherited condition in which a child lacks an enzyme that protects red blood cells
  • Hemolytic anemias: the abnormal breakdown of red blood cells
  • Sickle cell disease: a common inherited disorder caused when the red blood cells become sticky and oddly shaped
  • Thalassemia (Cooley’s anemia): a genetic condition in which one of the two proteins that help make up hemoglobin in red blood cells is lacking
  • Neutropenia: caused by a decreased amount of white blood cells that may be caused by disease or chemotherapy treatment
  • Anemia: due to a chronic condition such as kidney disease, cancer, or lead poisoning    
Types of White Blood Cell Diseases We Treat
  • Neutropenia: a condition caused by a decrease of white blood cells, as a result of disease or chemotherapy treatment
  • Leukemia: a cancer of the blood that develops in the spongy center of some bones (called the bone marrow)
  • Lymphoma: a blood cancer that develops in your child’s lymph system and includes two types: Hodgkin and non-Hodgkin lymphoma
  • Myelodysplastic syndrome: blood cancer affecting the bone marrow
Types of Platelets Diseases We Treat
  • Thrombocytopenia: a condition caused by too few platelets and results in abnormal bleeding
  • Thrombocytosis: a condition caused by too many platelets, which can lead to clots in the blood vessels
  • Idiopathic thrombocytopenic purpura: caused by a low number of platelets that results in abnormal bruising and bleeding
  • Qualitative platelet disorders
Caring for Children With Hemophilia

Our pediatric hematology experts are knowledgeable in treating children with hemophilia, an inherited, uncontrolled bleeding disorder. Children diagnosed with hemophilia either lack or have a low supply of proteins in their blood called “factors:” factor VIII or factor IX. These factors help your child’s blood to clot after an injury, preventing excessive bleeding.

There are three main types of hemophilia:
  • hemophilia A: the most common form, caused by a lack of blood clotting factor VIII
  • hemophilia B: caused by a low supply of factor IX
  • von Willebrand disease (vWF): this type of hemophilia causes prolonged bleeding  
Symptoms of hemophilia include:
  • excessive bleeding
  • bruising easily
  • joint bleeds (causing chronic pain and immobility)
  • bleeding into the muscles (causing swelling, pain, and redness)
  • bleeding from injury or in the brain (brain hemorrhage)
Treatment for hemophilia depends on your child’s severity and may include:
  • factor concentrates
  • blood transfusions
  • surgery
  • limiting contact sports
  • immunizations administered under the skin rather than in the muscle
Convenient Pediatric Hematology Services
Many treatments and other services are offered at Nemours, including:
  • chemotherapy: offered Monday through Friday, each of our chemotherapy rooms are equipped with TVs, DVDs, toys, age-appropriate Wii video games, and other services to help distract your child from treatment
  • specialized blood testing and analysis in our state-of-art lab
  • blood banking: a process that takes place in a hospital-based lab to ensure donated blood is safe before it’s used for transfusions
  • transfusions: a procedure in which your child is given whole blood or one part of it through an intravenous (IV) line
  • bone marrow transplant: a procedure that destroys cancer or abnormal cells with chemotherapy, and then re-introduces healthy donor stem cells in your child’s body

In addition to specialized treatments, we offer complementary services to help kids feel better physically and emotionally, such as:

  • Pet therapy: Teams of dogs and their handlers visit children and families in waiting rooms each week to provide a calming distraction to children as they interact with the dogs.
  • Art therapy: With the help of volunteers, children with cancer are encouraged to express their artistic talents with drawings and paintings, many of which grace the walls of our clinic.
  • Beaded journey: This program offers a distraction to children receiving chemotherapy and other treatments by giving them a different colored bead documenting the various procedures on their journey. Volunteers come to the clinic with sewing machines and work with children, helping them sew on the beads to create fun pillowcases, puppets, and other keepsake items.
