Body produces white blood cells (leukocytes), which help fight bacterial infections, viruses and fungi. If your child has too few or too many white blood cells, in general, here's what it means: Low white blood cell count (leukopenia) means having too few leukocytes circulating in the blood. A long-term low white blood cell count increases the risk of infections and may be caused by a number of different diseases and conditions. High white blood cell count (leukocytosis) means having too many leukocytes circulating in the blood, usually from having an infection. A number of different diseases and conditions may cause a long-term high white blood cell count.
Patients with sickle cell anemia were treated with daily doses of hydroxyurea, to assess pharmacokinetics, toxicity, and increase in fetal hemoglobin (Hb) production in response to the drug. Plasma hydroxyurea clearances were not a useful guide to maximum tolerated doses of the drug. The mean daily single oral dose that could be maintained for at least 16 weeks was 21 mg/kg (range, 10 to 35 mg/kg).
Treatments for white blood cell disorders depend on several factors, including: The type of disorder, The extent of the disorder, Your child’s overall health, Your child’s response to treatment, Your preferences Our treatments for your child’s white blood cell disorder may include: Chemotherapy, Radiation, Antibiotics, Colony-stimulating factors (these increase the body’s production of blood cells), Drugs to suppress the immune system Stem cell transplantation may be useful for some types of severe white blood cell disorders, particularly those caused by bone marrow problems
About 12% of children born with transfusion-dependent β thalassaemia are actually transfused, and less than 40% of those transfused obtain adequate iron-chelation therapy. About 100 000 patients are currently living with regular transfusions, and at least 3000 die annually in their teens or early 20s from uncontrolled iron overload. No comparable data are available for sickle-cell disorders.
