Eosinophils are white blood cells formed elements of the group, which functions are phagocytosis (absorption foreign agents) involved in IgE synthesis, absorption and binding of inflammatory mediators, as well as participation in the antiparasitic Immunity. Properties of eosinophils in the child, and the rate of possible causes shifts every doctor should know. Above normal may be an indication of parasitic or allergic diseases.
How to determine the level of
blood eosinophils are counted during clinical (total) assay. This is the least numerous cell. For the analysis is taken venous or capillary blood child. The study is mandatory and requires no special training. At the same time can carry out the analysis of feces and urine. The only condition - the refusal of food intake on the eve of the material.
Taken blood was diluted and placed in a special chamber (Goryaeva). To see eosinophils, a smear of blood is treated with a dye and then the cells were counted in the specialist field of view under magnification. They are large (more red blood cells), and the core of their colored in dark purple color and consists of 2 lobes.
Norma depending on age
The proportion of these cells is 1-6% of the total number of white blood cells - is the norm of eosinophils in children. Unlike red blood cells and other leukocytes, this figure more permanent. There are only slight variations depending on the age. In infants (during the first 2 weeks of life), the number is within the range of 1-6%. A child 2 years of birth is considered to be a normal eosinophil count 1-7%. In 4 years, this figure is normally 1-6%.
Norm of eosinophils in children, the table by age:
| Age of the child | The percentage of eosinophils |
| 1 to day 14 | 1-6% |
| to a year | 1-5% |
| 1-2 years | 1-7% |
| 2 and 3 years | 1-6% |
| up to 5 years | 1-6% |
| 6-7 years | 1-5% |
| 8-11 years | 1-5% |
| 12-15 years | 1-5% |
| 16 and older | 1-5% |
What is considered a deviation
Abnormal blood eosinophils in children is almost always indicates pathology. Increase of cells in the blood (up to 10% or more) is facilitated by:
- Worm infestation (infestation round, tapeworms and flukes). Eosinophilia cause trichinosis, ascariasis, trichocephalosis, strongyloidiasis, Enterobiasis, taeniasis, beef tapeworm infection, toxocariasis, hydatidosis, cysticercosis, fascioliasis, opisthorchiasis, bothriocephaliasis, schistosomiasis and other disease.
- Protozoozy (giardiasis, cryptosporidiosis, amebiasis, malaria, balantidiasis).
- Malignancies.
- Allergic diseases (asthma, hay fever, atopic dermatitis shape, allergy to food additives and foods, pollen, dust, animal hair, allergic rhinitis).
- Infectious pathology (mononucleosis, scarlet fever, tuberculosis).
- Systemic diseases (scleroderma, periarteritis, juvenile form of rheumatoid arthritis).
- Pathology of blood (cancer, benign tumors, polycythemia, lymphoma).
- Immunodeficiency states (Wiskott-Aldrich syndrome).
- Skin disorders (psoriasis, herpes, eczema).
- Vasculitis.
- Extensive burns.
- Taking medicines.
- Insufficient production of immunoglobulins.
- Congenital heart defects.
- Splenectomy.
- Effects on the body to ionizing radiation.
- Lack of magnesium.
To reduce the child of eosinophils in the blood lead:
- increased adrenocortical function (resulting in enhanced generation of corticosteroids and delay blood cells in the bone marrow);
- poisoning by heavy metals;
- septic conditions;
- purulent diseases (pyoderma, abscesses, phlegmon, necrosis);
- early stage inflammatory diseases.
Eosinophilia or hypoeosinophilia in infants and older children is an indication to the comprehensive survey. You may need a general analysis of feces, feces study on helminth eggs, ELISA (enzyme-linked immunosorbent assay) bacteriological examination, ultrasound, CT and MRI, biochemical blood tests, physical examination and virological research. Scheme therapy depends on etiological factor.
