Having received the results of a clinical blood test, each parent is in a hurry to find out for himself whether everything is in order. Fine, if all the indicators within the normal range, but it happens that the result goes beyond its borders. Incomprehensible names of the blood components may frighten inexperienced moms and dads.
And the factor that caused the deviation from the norm most of all worries. If the analysis form contains elevated eosinophils in the blood of a child, first of all, you need to know the reasons for this result. For this it is important to understand the functions of this type of cells, the reasons for increasing their number and other symptoms of diseases associated with eosinophilia.
Purpose of eosinophils
First of all, it should be noted that eosinophils are one of the nine types of white blood cells – cells that guard immunity. They recognize invading pathogens and stimulate immune responses. The action of eosinophils is manifested in the cytotoxic reaction to parasites. Abnormality of this indicator also indicates that something is perceived by the body as an allergen.
Indicators of an increase
For different ages, the rate of eosinophils in the blood of children will also be different. In comparison with adults, their number in children is slightly higher, since the child’s immunity is only being formed. Normal laboratory values are as follows:
- For newborns – 1-6
- In children up to two weeks of age – 1-6
- From two weeks to one year – 1-5
- From a year to two years – 1-7
- Two to five years old – 1-6
- From six to sixteen years – 1-5
Causes of eosinophilia
The reasons for increasing the number of this type of leukocytes in the body of a baby can be quite a lot, for example:
- Increasing the body’s sensitivity to exogenous or endogenous antigens. In such a case, bronchial asthma, pollinosis, allergic rhinitis, eosinophilic granulomatosis with polyangiitis, skin and food allergic reactions can provoke it.
- Allergy to medication. For example, penicillins, tetracyclines, sulfonamides, aspirin, chloramphenicol, aminophylline and similar drugs.
- Some skin diseases.
- Infection with parasites. Most often these are lamblia, roundworm, echinococcus larvae, trichinae, liver flukes and others.
- Acute manifestations of infectious diseases such as chickenpox, tuberculosis, scarlet fever, gonorrhea, infectious mononucleosis.
- Malignant neoplasms.
- Proliferative diseases of the blood system – lymphoma, acute and chronic leukemia, lymphogranulomatosis, hypereosinophilic syndrome, polycythemia, and others.
- Inflammation in the connective tissue such as, for example, rheumatoid arthritis or polyarteritis nodosa, as well as systemic scleroderma.
- Pulmonary diseases – eosinophilic pleurisy, eosinophilic pneumonia, sarcoidosis, histiocytosis from Langerhans cells, pulmonary eosinophilic infiltration (Lefler’s disease).
Symptoms of the disease
Since there are many reasons for a child to increase eosinophils in the blood, the symptoms may be different.
When infected with parasites, the symptoms are usually non-specific, they can be overlooked or taken as signs of another disease. Reasons to suspect parasitic invasion are as follows:
- Changes in appetite;
- Feels lethargy and fatigue;
- An itchy irritation of the anus occurs;
- Weight is reduced;
- There is pain in the muscles;
- Manifest allergic reactions on the skin.
If the reason for the increase in leukocytes in the blood is a reaction to an allergen, then the symptoms will be corresponding to allergic diseases:
- Skin rash, with itching;
- Runny nose, sneezing, swelling;
- Dry cough, shortness of breath, choking;
- Itching, redness of the eyes, tearing.
Anxiety for the child pushes parents to turn to additional examinations. To get a more accurate result, it is worth observing some rules for taking a blood test:
- Since after taking food should increase leukocytes, then donate blood is best on an empty stomach;
- Theoretically, the indicators also depend on the time of day at which the analysis was made, therefore it is preferable to do it in the morning;
- If, during the course of the disease, UAC surrenders several times, then it will be correct to observe the same conditions (for example, always in the morning and before meals) so that the indicators are affected by as few factors as possible;
- If the child is healthy, and eosinophilia persists for a long time, it is necessary to pass the analysis on the level of total immunoglobulin E, in order to determine the tendency to allergic reactions.
Dr. Komarovsky says the following about raising eosinophils in a child: “It may be present after suffering diseases, usually bacterial, during the recovery phase. But if the general condition of the child is normal, then the increase in the number of eosinophils in itself should not cause concern to the parents. us-s.us
If the child is healthy, then it is best to monitor his condition and be examined (make a KLA) in about 3-4 months.
Norm eosinophil in children – video
Any inconsistency with normal indicators as a result of the KLA is very worrying parents. In order to dispel baseless alarms, it is necessary to understand that this analysis is generally what it can tell you and what to do when a deviation from the norm is detected.
In this video, Dr. Komarovsky will help parents navigate the complex names of blood cells and understand their purpose, as well as determine the type of disease, which is indicated by a change in indicators.
