Elevated eosinophils in the blood of a child: what to do?

Eosinophils — a subspecies of white blood cells, the purpose of which is to destroy foreign agents, trapped in the human body. Also these components act as markers that determine allergies, infectious or parasitic lesion, tissue inflammation and malignant tumors. They penetrate into the area of inflammation and triggers the self-destruction of cells surrounding the parasite. This allows them to surround a foreign substance membrane. The latter becomes a sign of powerful immune cells.


In addition, eosinophils can accumulate and release inflammatory mediators, which participate in immune reactions. Also, these blood cells can destroy pathogens. Eosinophils are called microphages.

The norm

In adult blood eosinophils should be no more than 5 % of the total number of leukocytes. In the morning the level of these immune cells can be increased by 15% compared to the norm, at night — 30 %. The level of eosinophils is increased in women undergoing ovulation.

As for children, the normal content of eosinophils in the blood ranges up to 5 years. In the first 2 weeks after birth the number of these immune cells in the blood varies from 1 to 6 %. In the first year of life, the normal rate content does not exceed 5 %, and in the second year it can reach 7 %. With 2 to 5 years ranges from 1 to 6 %. After 5 years, the level of eosinophils in the blood does not exceed 5 %. If the child has significantly increased this type of white blood cells (over 15 %), this may indicate the development of a certain pathology.


To determine the level of these components by using the General analysis of blood. To get a reliable answer, on the eve of blood donation it is necessary to limit the consumption of sweets, and the analysis should be performed in the morning on an empty stomach.

Newborn eosinophils may be increased for the following reasons:

  • hemolytic disease;
  • atopic dermatitis;
  • the presence of Staphylococcus aureus in the intestine;
  • serum sickness.

A child up to 3 years, the growth level of these immune cells occurs while angioedema, allergic reactions to drugs atopic dermatitis. The cause of the increased levels of eosinophils, a child older than 3 years are:

  • acute deficiency of magnesium ions;
  • bronchial asthma;
  • allergic rhinitis;
  • allergic rash (eczema, pemphigus vulgaris);
  • cancer of the blood;
  • chickenpox;
  • scarlet fever;
  • toxoplasmosis
  • appendicitis;
  • infection with parasites: Giardia, Ascaris, Trichinella, filarial, etc.;
  • autoimmune diseases (rheumatic arthritis, lupus erythematosus);
  • taking some medicines containing acetylsalicylic acid, penicillin, adrenocorticotropic hormone and nitrofurans.

Also, the child may experience a simultaneous increase in the number of lymphocytes and eosinophils. The reasons for this phenomenon are viral infection occurred on the background of allergies, worm infestation, scarlet fever and Epstein — Barr. If a child has been the growth of not only eosinophils but also monocytes, this may indicate the development of mononucleosis and tuberculosis and sarcoidosis.

In infectious diseases a slight increase in levels of these immune cells occurs in the recovery period.

What to do if elevated eosinophils?

If blood child an increase in the levels of these cells, it is necessary to pass a complex medical examination. The only way to find out the cause of the increase level of eosinophils. Such studies include:

  • Analysis of feces for parasites.
  • Ultrasound examination of abdominal cavity organs.
  • A swab from the nasopharynx to the eosinophils.
  • X-rays of the lungs.
  • Functional tests of the liver and kidneys.
  • Spirometry and cold samples.
  • Allergy tests.

    Treatment is directed primarily at eliminating the disease that caused the increase in the concentration of these blood components. If a child suffers from allergies, treatment will the doctor-allergist. When pulmonary issues, the treatment prescribed by the pulmonologist and in parasitic infections — infectious disease. If a child has suspected cancer of the blood, he will need the help of an oncologist and hematologist. In acute deficiency of magnesium ions is small, the patient should take vitamins and minerals that will select the doctor.

    After effective treatment of the underlying disease, the level of immune cells in the blood gradually returns to normal. In order to identify the increase of eosinophils, need to regularly take the blood test. When signs of the disease, children should immediately show the pediatrician.
