What is White blood cell disorder in children?

They refer to a series of conditions that occur when the body has an abnormal count of white blood cells or leukocytes, which help fight bacterial, fungal, or viral infections.

When there is a low number of leukocytes it is called leukopenia, and when the count is high, leukocytosis occurs.

White blood cell disorder in children, according to clinical research, can appear for any of the following reasons:

Genetics (transmitted from parents to children).
External environmental factors.
Malignant neoplasms.
Other pathologies.
Immune problems.

There is a wide variety of white blood cells, each with a specific task to fight various diseases, the most common being:

Basophils.
Eosinophils.
Lymphocytes.
Monocytes.
Neutrophils.

Your child may have a low white blood cell count (leukopenia) that reduces their body’s ability to fight infections or have a high number of leukocytes circulating in the blood, generally due to an infectious condition, an autoimmune response of the body, or the presence of cancer.

Signs and symptoms White blood cell disorder in children

The symptoms depend on the cause but generally include:

Diagnosis and treatment White blood cell disorder in children

To obtain an adequate diagnosis, you must see a specialist, who will analyze your child’s symptoms and clinical history, and then perform a physical examination. They will also order a series of tests to determine the cause of the white blood cell disorders, such as:

Bone marrow analysis.
Tissue biopsy.
Blood test.
Molecular examination.
Genetic testing.

The treatment to follow will depend on the symptoms, the type of white blood cell disorder, and its severity, which may include:

Antibiotics.
Medications that help stimulate the production of white blood cells from the bone marrow.
Bone marrow transplant.
