Produced in the bone marrow, white blood cells (also called leukocytes) work in the immune system to protect the body against disease by detecting and fighting foreign molecules and other substances that often lead to infection. There are 5 different types of white blood cells including Basophils, Eosinophils, Lymphocytes, Monocytes, and Neutrophils. Each of these white blood cell types are responsible for responding to different pathogens in the immune process. The normal total white cell count ranges from 4,500-10,000 white cells per microliter. Low white blood count (leukopenia) can have different symptoms, but there are also many treatments for this condition.
What is Leukopenia?
Leukopenia is defined as a low white blood cell count that falls below 4,000 cells per microliter. The most common causes of leukopenia include:
- Viral infections that decrease the ability of the bone marrow to produce white blood cells
- Inherited disorders such as myelokathexis or Kostmann's syndrome that prevent the white cells from entering the bloodstream
- Cancer of the bone that damages the bone marrow
- Chemotherapy and other drugs (such as antibiotics and diuretics) that disrupt the bone marrow or that destroy the white blood cells after they are formed
- Autoimmune disorders such as lupus
- Other disorders such as hypersplenism that can destroy blood cells as they are produced
- Massive infections that overwhelm the production of white blood cells so they cannot be produced fast enough by the body
Symptoms and Complications of Leukopenia
Symptoms of leukopenia vary from person to person and depend on the cause and severity of the problem. Lack of energy, Headache, fever, and irritability are common symptoms. You may also notice that you may have more infections and sores in your mouth. Sometimes, a person with leukopenia may develop a desire for warm liquids. Complications of leukopenia may include:
Treatments for Leukopenia
Because there are so many causes of leukopenia, the treatments for this disorder are varied. All of these treatments must be supervised by your healthcare provider.
The most critical point to know about leukopenia is that you MUST work with your healthcare provider to find the cause of the disorder. Only your provider will be able to diagnose the cause of leukopenia and prescribe the correct treatments. In addition, you must be sure to let any doctor, dentist or other healthcare provider know about your leukopenia BEFORE they provide any care or medications to you. With the proper care and treatment, most causes of leukopenia can be reversed.
