what causes high white blood cell count in newborns?

Leukocytosis refers to an increase in the total number of white blood cells, usually it is physiological or infectious in neonate and the counts rarely exceed 30,000/mm3. Hyperleukocytosis (WBC > 100,000/mm3) is rare and can be due to leukaemia, leukocyte adhesion defect and myeloproliferative disorders.

A high white blood cell count isn't a specific disease in itself, but it can indicate an underlying problem, such as infection, stress, inflammation, trauma, allergy, or certain diseases. That's why a high white blood cell count usually requires further investigation.

The total WBC count and neutrophil count in neonates younger than 1 week are physiologically higher than those of children and adults and the counts usually range from 9,000 to 30,000/mm3 [1].

Rozanski says, a low white blood cell count results from chemotherapy, sepsis (overwhelming infection), or parvovirus. The virus destroys all rapidly dividing cells, including those in the bone marrow and cells lining the gastrointestinal tract.

The most common causes of elevated white blood cell counts are infections and inflammation. Some cases of leucocytosis are the result of an immune reaction. A small number of cases are caused by a blood cancer. Treatments for high white blood cell counts typically focus on addressing the underlying disease.

When you get sick, your white blood cell count is higher than normal. This is because your body is releasing more of these cells to fight the infection.

The bottom line. Newborns are especially vulnerable to infection by a type of germ called Staphylococcus aureus. Staph is a bacterium that is present in most people's noses and skin. It can be life-threatening, especially when it causes infections in newborns.

A high white blood cell count alone doesn't cause any symptoms. The symptoms you feel may come from the medical problem that your white blood cells are fighting. For example, if you have pneumonia, you may have a fever and trouble breathing.

An increase in white blood cells is known as leukocytosis. It typically occurs in response to the following conditions: infection. immunosuppression.

White blood cell count is increased in pregnancy with the lower limit of the reference range being typically 6,000/cumm. Leucocytosis, occurring during pregnancy is due to the physiologic stress induced by the pregnant state [8]. Neutrophils are the major type of leucocytes on differential counts [9, 10].

['An increased production of white blood cells to fight an infection.', 'A reaction to a drug that increases white blood cell production.', 'A disease of bone marrow, causing abnormally high production of white blood cells.']

Typically, white blood cell count is elevated during pregnancy, with the lower limit of the reference range being around 6,000 cells per μl and the upper limit around 17,000 cells per μl. 5. The stress imposed on the body through pregnancy causes this rise in white blood cells.

More serious conditions that may cause high white blood cell counts include blood disorders, including: Leukemia. Lymphoma. Bone marrow disorders such as polycythemia vera or myelofibrosis.

Most infections in newborns are caused by bacteria, while some are caused by viruses. Symptoms of infection include temperature above 38.0 degrees C, poor feeding, irritability, excessive sleepiness, rapid breathing and change in behaviour.

When your monocyte level is high — known as monocytosis — it means your body is fighting something. Some conditions that can cause an increase in the monocytes in your blood are: viral infections, such as infectious mononucleosis, mumps, and measles. parasitic infections.

Neutrophils, which account for about 70% of white blood cells, can increase in response to bacterial infections as well as to physical or emotional stress. A high lymphocyte count may occur when there is a viral or bacterial infection.

A high white blood cell count is also called leukocytosis.
