Increased eosinophils in the blood of a child. Reasons for what absolute value means in analysis

Date: 19.07.2019

The health of the child is the most important thing for parents. A fairly large number of different factors help to determine its level. One of the most extensive and revealing factors - general analysis blood. By conducting this study, you can determine the level of eosinophils in the blood - cells that perform protective function... This indicator is one of the most important, because it indicates the level of the body's defenses.

Eosinophils what are they?

Eosinophils are special cells that are found in the blood. The main function that they perform is protective. They are an integral part of leukocyte formula.

The cells got this name due to their peculiarity revealed during the diagnosis. They respond excellently to a special laboratory dye called eosin, which makes them easy to detect.

The appearance of the cell resembles a binuclear amoeba. It can easily overcome cell barriers and enter tissues. In addition, this cell tends to accumulate in the necessary areas, as a rule, these are damaged areas.

These cells are in the blood for no more than 1 hour, and after that they move into the tissues.

In order to determine the level of their content, specialists most often prescribe a general blood test. Typically, it is taken from a finger or from a vein.

In addition, these cells are responsible for the accumulation and release of so-called inflammatory mediators. These substances include:

Histamine.
Phospholipase.
Other substances.

These mediators are involved in different reactions immune nature, for example, cause anaphylactic shock... Also, these cells have the ability to destroy small microbial organisms.

These cells are a special type of white blood cell. They are produced in the bone marrow and spread throughout the body along with the bloodstream. It is with the blood that they go to various tissues, formations, organs.

As a rule, these cells are in the blood for no more than an hour, so their content there is quite low. Their largest concentrations are observed in:

Small vessels.
Lungs.
The gastrointestinal tract.

In these places, they neutralize various foreign microorganisms that have got inside the child.

Various microorganisms can enter the child due to adverse effects environment or the habit of putting dirty things in your mouth. The appearance of harmful microorganisms for a long time may not appear in any way; only a blood test can help to identify the fact of their presence. That is why, it is very important to know the norms of these special leukocytes in the standard formula.

At the age from 0 to 1 month - 1.2 - 6.2%
At the age from 1 month to 1 year - 1.2 - 5.2%
Between the ages of 1 and 2.5 years - 1.2 - 7.2%
Between the ages of 2.5 and 6 years - 1.2 - 6.2%
From 6 to 12 years old - 1.2 - 5.7%
Between the ages of 12 and 15 - 1.2 -5.2%

Important! Changes in the level of eosinophils indicate the development of any disorders in the baby's body.

Increased eosinophils in the blood of a child: causes and consequences

The condition when the level of special leukocytes in the blood exceeds the norm is called eosinophilia. The higher the level of eosinophils in the blood, the more serious the reaction to the ingress of harmful particles into the body.

A test such as a blood test helps to establish the level of these cells. However, its performance can be affected by:

Food intake.
Active sports.

That is why it is best to refrain from eating in the morning and from active physical activity the day before.

Sometimes there are cases of an increase in the level of such leukocytes up to 50%. If during the delivery of the general analysis an increase was revealed acceptable level, then the specialist will most likely prescribe an additional serological analysis... This blood test helps to establish the presence of antibodies that are produced when foreign microorganisms enter the body. The need for an appointment additional research due to the imperfection of conventional research.

This phenomenon primarily affects organs such as:

Pancreas.
Stomach.
Liver.

Development malignant diseases blood.

Generally, the more severe the illness, the higher the level of eosinophils.

Autoimmune diseases.
Rheumatic diseases.
Diseases of the skin.

A specific reaction is manifested when the body reacts to the influence of allergens or external stimuli.

Influence of staphylococci.
Magnesium deficiency.

In newborns, an increase in the level of these cells in the blood may indicate:

Immunity to cow's milk.
Intolerance to individual drugs.
Individual features.

In addition to the main factors that affect the level of eosinophils, they can be affected by various medications... Drugs that cause such a reaction include:

Sulfanilamide.
Aspirin.
Nitrofuran.

Also, the level of these cells may increase if a child develops diseases such as:

Dermatosis.
Syphilis.
Asthma.
Rheumatism.
Diseases of the blood.
Blood cancer.
Tuberculosis.
Endocrine system diseases.
Hypothyroidism.

Also, the level of eosinophils can increase due to burns, frostbite, taking antibiotics or hormonal drugs.

Most often, such a specific reaction of the body is due to the influence of food allergens or medications.

These cells actively fight various allergens that enter the body from the environment. Such a process most often develops in children due to the specific reaction of the body to the influence external factors... That is why the main reason for the increase in their level in child's body is precisely the penetration or influence of various irritants or foreign microorganisms.

How to reduce blood eosinophils in children?

It is not worth treating eosinophilia as a separate disease. To normalize the level of these cells, it is first of all necessary to determine which factor was the cause of the increase. As a rule, when determining the factor that led to an increase in the number of these cells, the specialist prescribes measures for the treatment of aspen disease.

Selection medicines first of all, it will depend on the type of disease, its severity, stage of development and concomitant diseases. Treatment can also include avoiding certain medical supplies or introducing lifestyle changes.

Important! The rates of increase or decrease in eosinophils in the blood are quite a relative concept. For example, with low blood levels, they can accumulate in organs. However, their total number remains unchanged.

That is why, in the majority of cases, changes in the level of these cells indicate changes in the body and do not necessarily indicate the development of the disease.

With proper treatment of the underlying disease, the level of these cells in the blood and tissues will return to normal values over time.

To summarize, we can say that eosinophils are quite important cells. They represent special kind leukocytes, which creates a shell around the harmful microorganism or damage. Thanks to the work of these cells, defense mechanisms in the body, a harmful microorganism is found faster, and as a result, they rather begin to fight it. Depending on the age of the child, the rate of these cells in the blood also fluctuates. The highest indicator - 7.2% can be recorded at the age from 1 to 2.5 years.

Anna Kuznetsova, 35 years old (Moscow): When my son was 3 years old, they faced a similar problem. He was found to have an increase in the level of eosinophils by 20%. For a long time they figured out what the reason was, it turned out that the level of these cells was influenced by a food allergen. We immediately eliminated this product from the diet and over time, everything returned to normal.

Ekaterina Orlova, 26 years old (Omsk): Recently, my daughter and I underwent examination after a cold. The doctor recorded an increase in the level of eosinophils, scared me possible diseases... But I did not believe him and took my daughter to another hospital for examination. Indeed, the increase turned out to be caused by the influence of the drug. After this incident, I do not strongly trust the opinion of doctors about the significance of such an indicator as this one.

Anton Gudz, 21 years old (Donetsk): Recently gave birth to a son and at the next medical examination we were told that it is necessary to undergo a general blood test. To be honest, I do not see a special need for this, since the rest of the indicators, according to the doctor, fully indicate that the baby is healthy.

Nadezhda Evsyukova, 44 years old (Irkutsk): I am a mother of 3 children and I always carefully monitor their health. However, children are constantly pulling something into their mouths. And so it happened with my daughter, the doctors diagnosed elevated level eosinophils. It turned out that he had increased due to the fact that she licked a dirty toy. But thanks to the fact that we started treatment on time, everything worked out.

Angelina Ivanova, 22 years old (Omsk): My husband and I wanted a child for a very long time, and when our long-awaited son was born, we decided to carefully monitor his health. My son often caught a cold, and we constantly visited the clinic and tried to strengthen his immunity with fruits. However, during the next general blood test, the doctor said that he had an increased level of eosinophils in his blood. They immediately began to look for the reason. It turned out to be quite commonplace, he just developed an allergy to oranges. I am very glad that we managed to find it in time until it caused serious consequences.

If a blood test showed that eosinophils are increased in a child, then it is necessary to identify the reasons that caused this change. In this way, the baby's body can react to many irritants: insect bites, vaccinations, allergens, helminthic invasion, and a bacterial or viral infection. Eosinophilia in children is not considered an independent pathology, but it can be a sign of a disease. To normalize the leukocyte formula, you should undergo an examination and remove the cause of the changes.

What are eosinophils

A type of white blood cell produced by the bone marrow is called eosinophils. Primary data location blood cells- in the respiratory organs chest(lungs, bronchi), intestines, stomach and capillaries. The main task of eosinophils is to destroy foreign aggressive agents that have penetrated the internal environment of the body. This is evidenced by the resulting inflammatory reaction with the release of cationic protein.

The main functions of eosinophils:

absorption (phagocytosis) of histamine;
the release of an enzymatic protein that destroys the shell of dangerous agents;
production of biologically active enzymes;
participation in the production of plasminogen (an indicator of the anticoagulant system).

What eosinophils show in a blood test

As a rule, eosinophils are increased in a child due to the active entry of foreign protein into the bloodstream. The change in indicators occurs with different pathological conditions. Eosinophils are able to indicate the following dangerous diseases:

infections (bacterial, viral or helminth infection);
allergies;
inflammation in organs and tissues;
cancers;
pathology of immunity.

The rate of eosinophils in children

The absolute number of eosinophil levels in older juveniles is normal performance in adults. The numerical value of the leukocyte formula is calculated in relative terms, and the rate of eosinophils in the blood in children depends on the age of the child:

Elevated eosinophils in the blood of a child

To determine the number of these blood cells, doctors will order a complete blood count and urine test. If the eosinophilic cationic protein is elevated in the child, then the parents should go with the baby full examination to identify a latent disease. A high number of these white blood cells is called eosinophilia. It can be small - it contains up to 15% of bodies, moderate - up to 20%, high - more than 20%. In severe situations, the deviation is up to 50% of the content of eosinophils. In addition to an increase in this type of leukocytes, analysis may show that monocytes are increased.

Clinical picture

If eosinophils are increased in a baby or an older child, then he will have a special clinical picture. With eosinophilia, signs of an allergic process appear on the background normal health baby:

swelling of the mucous membrane of the eyes;
hyperemia of the mucous surfaces of the nasopharynx and conjunctiva;
allergic rhinitis;
profuse lacrimation;
nasal congestion;
bronchospasm;
rash on the skin.

In a newborn baby high rates white blood cells are hazardous to health. They cause general weakness in the baby, lethargy, pathological reflexes, anxiety and bad dream... Such a child slowly gains body weight, because he refuses to suckle and eats little. Experts note that the more actively the pathological process in the body of a newborn develops, the more pronounced eosinophilia is.

Causes

An increase in the number of leukocyte cells is caused by many causes and pathologies developing in the baby's body:

What to do with eosinophilia

There is no special treatment for eosinophilia, but the doctor must diagnose and treat the underlying disease. To do this, patients first take tests and undergo additional examinations and then receive the necessary medications. Treatments for common diseases raising white blood cells can be:

The task of eosinophils, a type of white blood cell, is to destroy a foreign protein in the blood. These substances are formed in the bone marrow, after which they enter the bloodstream for several hours, and already from the bloodstream are distributed into the tissues. It is there that they do their main "work". Eosinophils live for about 1-2 weeks. When a person does not have allergies, inflammations or oncology, these substances are within the normal range. The change in the number is interpreted with different points vision. Let's take a closer look at the concept of eosinophils and consider what their content in a blood test means.

Eosinophil tasks

The main task of the activity of eosinophils is the elimination of foreign harmful agents. Their destruction occurs at the extracellular level, and their capabilities include the elimination of rather large organisms. Exposure begins with the release of the contents of intracellular granules. Compared to neutrophils, the ability to phagocytosis in the agents we are considering is less, but it is still present. This is not their main task, but they can destroy and absorb microbes.

Let's list the main functions of eosinophilic granulocytes:

They have a toxic effect on helminths.
Eliminate action biologically active substances causing allergies.
They help to eliminate the consequences of the activity of bioactive substances that were produced by mast cells and basophils. The latter are the main causative agents of allergic reactions. They also affect development severe forms diseases - Quincke's edema and anaphylactic shock.
Develop a high sensitivity response.
Awakens activity to kill bacteria.
Eliminate foreign cells by absorbing them.

Eosinophils fight allergens to stabilize a child or adult

Rate of indicator in children

Eosinophilic granulocytes are part of the leukocyte blood count. Determining their number is easiest and most reliable with the help of a general blood test.

Normal eosinophilic cationic protein indices can fluctuate, which is directly related to age. Children have more eosinophilic granulocytes than adults. So, in newborn babies - up to 8%, in older children - up to 5-6%.

The indicators that determine the rate will vary depending on the laboratory conducting the study. This is influenced by the reagents used, equipment and units of measurement adopted in a particular medical institution. Most laboratories determine the number of eosinophilic granulocytes as a percentage of the total all leukocytes. Those. as a result, we see not the total number of cells, but their proportion among leukocytes.

It is important to keep in mind that the result obtained is relative. Based on this technique, eosinophilic granulocytes are normally:

for newborn babies - from 1 to 6-8%;
for babies from 15 days to a year - 1-5%;
1-2 years - 1-7%;
205 years - 1-6%;
5-15 years old - 1-4%;
over 15 years of age - up to 5%.

Eosinophil counts are highest in infancy

Existing tables allow you to independently determine whether the test result is normal or there are deviations. To calculate the absolute number of eosinophilic granulocytes in the blood, the following unit of measurement is taken as a basis: 10 ^ 9 / L.

The following indicators are considered the norm:

from birth to one year - 0.05-0.4;
from 1 year to 6 years old - 0.02-0.3;
for children from 6 years old and adults - 0.02-0.5.

Why are eosinophils elevated?

A condition when the number of eosinophilic granulocytes in the body increases to 10-15% in a person is called eosinophilia. This increase in eosinophils is accompanied by a slightly increased or normal white blood cell count. In the bone marrow, eosinophilic granulocytes are actively produced as defensive reaction on the appearance of foreign protein in the blood.

The increased content of the cationic protein of eosinophils affects the appearance of changes in the internal organs, which is a consequence of a lack of oxygen in tissues and cells.

Eosinophilic cationic protein indices can become higher for various reasons:

Protective reaction to exposure to allergens. The immune system begins to work actively when there are allergic lesions skin or bronchial asthma... It is immunity that gives a signal to increase the production of eosinophilic granulocytes.
The process of recovering from an infection. The body recovers and begins to strengthen the immune system, creating a large number of eosinophils.
The presence of helminthic invasions (ascariasis, toxocariasis, giardiasis, opisthorchiasis). Being a chronic irritant, helminthic infestations provoke the immune system to produce eosinophils on a regular basis. It is important to know that fluctuations in the number of eosinophilic granulocytes can be observed in healthy child... Sometimes, after re-passing the analysis, the first increased data are replaced by normal ones.

An increase in the number of eosinophils may indicate a possible helminthic invasion.

Diseases connective tissue(vasculitis, systemic lupus erythematosus, scleroderma). These diseases provoke the onset of inflammation in the body, followed by the production of a large number eosinophilic granulocytes.
Diseases at the level of the endocrine system.
Rheumatoid pathology.
Diseases of the blood, including cancer.
A number of skin diseases (eczema, dermatitis, pemphigus) (we recommend reading :).
Taking medications (adrenocorticotropic hormones, antibiotics, sulfonamides).
Consequences of frostbite and burns.
Lack of magnesium ions in the child's body.

An excess of the level of eosinophilic granulocytes by more than 20% is a reason to think seriously and consult a doctor. Often, the cause of this phenomenon is giardia, trichinella or roundworm. There are cases when the normal index increased immediately by 50%, which means that it is impossible to postpone the examination of the child for opisthorchiasis, because it is this disease gives such symptoms (we recommend reading :).

Increased eosinophils and monocytes

Monocytes and eosinophils increase in the presence of infectious processes (for more details in the article:). A typical example is mononucleosis in children and adults. A similar situation is also observed in patients with diseases of a fungal and viral nature, as well as with syphilis, tuberculosis, rickettsiosis and sarcoidosis.

Increased eosinophils and lymphocytes

The presence of viral infectious diseases in children with allergies often leads to an increase in the level of lymphocytes and eosinophils (see also:). A similar situation is possible in patients with helminthiasis and allergic dermatoses. These rates are also overestimated in adults and children taking antibiotics and sulfonamides.

To make sure that there is no helminthiasis, it is necessary to pass an analysis of feces for eggs of worms

False results

Consideration should be given to the possibility of erroneous determination of the number of eosinophilic granulocytes. They are always stained with eosin, while basophils do not stain at all, and neutrophils have a twofold potential. It happens that neutrophils also stain with eosin, and this affects the final picture. As a result, we will see a low neutrophil index and an increased one - eosinophils. For reliability, Dr. Komarovsky advises to re-analyze.

Why are eosinophils lowered?

A decreased content of eosinophils (less than 0.05) is called eosinopenia. Such a small number of cells shows that the body's defenses are weak and cannot withstand the acting harmful factors.

Why might the level get lower? Often the reason lies in the existing pathology:

some acute intestinal infectious diseases ( typhoid fever, dysentery);
acute appendicitis;
sepsis;
trauma, burns, surgery;
the first day of the development of myocardial infarction;
Availability acute inflammation(at first, the substances are completely absent, and then the excess of the norm is noted, which will indicate recovery).

Overstrain and stress can cause a decrease in the number of eosinophils.

A decrease in the level of eosinophilic granulocytes is sometimes not at all associated with pathology. Often, excessive physical exercise, overstrain in psychoemotional terms, the effect of adrenal hormones.

Effect of drugs on eosinophil levels

Eosinophils are very sensitive to a wide variety of medications. If a child is taking carbamazepine (an anticonvulsant drug), tetracycline, erythromycin, anti-TB drugs, or phenothiazides, the number of these types of blood cells may be increased.

An increase in cell levels is observed in patients taking penicillin, aminsalicylic acid, and methyldop. It is extremely important to test for allergies to a particular type of drug.

A decrease in eosinophilic granulocytes is a sign of developing inflammatory process in organism. Sepsis, intoxication of the body and purulent inflammation... After receiving the test results, you should discuss them with the lead doctor.

Instead of a conclusion

Eosinophils are important elements of the immune system, they are fighters against foreign substances leading to various problems in various areas: in the intestine, in genitourinary system, v oral cavity etc.

How do I fix the problem? The most important and important thing is to establish the cause of the change in the level of eosinophils. After the diagnosis is made, you should undergo a course of treatment and eliminate allergies, helminthic invasion or existing infection.

At least once a year, or even more often, the pediatrician gives a referral for testing. This is mainly a general analysis of blood and urine. Imagine the surprise of parents when a deviation from the norm of at least one of the indicators is found. Especially if deviations from the norm concern any type of leukocytes. Everyone knows that it is these blood cells that are responsible for human immunity. These bodies also include eosinophils. A detailed blood test can show how much their indicator differs from the one in the greater or lesser direction. When eosinophils are elevated in a child- this requires special attention.

Eosinophils are a subspecies of granular leukocytes. They acquired their name for their ability to respond to the reagent eosin. With its help, in laboratory conditions, it is possible to determine the number of these beneficial bodies in human blood. Due to their small size, their number is determined not by the number, but by the percentage of the total mass of the white bodies. For an adult without health disorders, such a rate in a blood test is 5%. In children, it is 3% higher. This is due to the fact that the matured organism is already familiar with those allergens that the child gets to know.

Eosinophils are created in the bone marrow and then travel to the bloodstream or capillaries. Ease of penetration due to the small size and structure of the body. By outward appearance they resemble an amoeba with two nuclei. Due to the amoebic mode of movement, these bodies easily penetrate into soft tissue, internal organs and human epithelium. Directly in the blood itself, they spend no more than one hour.

With a complete and detailed analysis, it can be found that eosinophils in the blood are increased. What does this mean and how to deal with it? Let's take a closer look.

Eosinophil functions

To begin with, it is worth understanding why they generally exist in human blood, and what functions they perform.

These small granules are needed to identify foreign bodies in cells and fight them. They react to histamines, toxins and pathogens.

One of the most important functions of eosinophils is to regulate the level of histamine in the blood. If in a child it differs significantly from the norm in a larger direction, then eosinophils temporarily suspend activity. In addition, they produce many useful biological compounds in the blood.

In newborns, the number of eosinophils is above the permissible limit. Why and what is it connected with? It's simple: food allergies, skin irritation. An increase in white blood cells can be diagnosed as eosinophilia when their number has gone beyond the acceptable upper limit.

The norm in children

What are their norms in children? The ratio of eosinophilic bodies in the blood of children to the total mass of leukocytes can be considered in the table compiled according to the norms of the leukocyte formula:

The largest numbers are in infants and 3 year olds. Such a level of eosinophils in a child is quite justified. But any shift from the permissible limit requires an immediate search for the reasons for the increase in the number of eosinophils, diagnosis and bringing them to normal.

Reasons for rejection

A number of factors can be distinguished that cause an increase in eosinophils in the blood of a child:

Antihistamine process. Leukocytes fight the allergen;
Response to helminth infection. There are many types of worms and almost all children become infected with them;
Various skin diseases, it does not matter: whether it is diaper rash or lichen;
Malignant tumors;
Diseases circulatory system and vessels;
Deficiency of magnesium in the blood.

If the child's level of these little bodies is exceeded by at least 15-20%, this indicates that the body contains foreign bodies... In this case, more detailed analysis blood to identify pathogenic organisms, due to which the child has increased eosinophils.

One of the most common causes in babies is infection with pinworms or roundworms. Hygiene accustoming to a child is not an easy task. It is also impossible to control the ingress of microorganisms with food and water.

The second most important is an allergic reaction. It can occur on absolutely any items: food, hygiene products, household chemicals or animal hair. It provokes an increase in eosinophilic bodies in the blood and can manifest itself on the body in the form of a rash, redness and irritation.

Eosinophilia as a disease

It is possible to diagnose the disease of eosinophilia when the level of leukocyte cells is increased by at least a third of the norm. It is rather difficult to characterize it as an independent disease. Basically, this disease manifests itself against the background of a more serious ailment. Elevated eosinophilic bodies in the blood may mean that the child's body is this moment fights another disease.

V medical practice there have been cases when a baby was diagnosed with eosinophilia from birth. It could have arisen for a reason congenital malformation heart, immunodeficiency or cancer. Also, eosinophilia can be observed in premature babies.

Signs of the disease

Sometimes, it is possible to determine the presence of elevated eosinophils in the blood of a child by the condition of the child and outward signs. Characteristic signs will be:

For allergies:

Redness, rashes;
Dermatitis, diaper rash;
dry skin, itching;

Sleep disorders;
Lack of appetite;
Itching in anus or genitals;
Change in body weight.

Caused by other diseases:

General malaise, weakness, lethargy;
Heart failure;
Anemia;
Increased body temperature.

These are not all the symptoms that occur with an increased level of eosinophils. Basically, the signs of the disease are similar to the underlying disease. This means that determine the presence of eosinophilia, only a blood leukogram will help.

There are three stages of eosinophilia: mild, moderate, and high or large eosinophilia. I would like to draw your attention to the latter in more detail. This degree of the disease is characterized by high levels of eosinophils in the blood. They can reach 15% or more. In this case, there is a risk of developing monocytosis or blood leukocytosis.

Monocyte level in healthy person is within 13%. They, like eosinophils, belong to granular leukocytes and their meeting indicates the presence of a dangerous infection or infection with helminths.

An increased number of leukocytes and eosinophilic bodies may develop against the background viral infections when treated with antibiotics. If a child falls ill with scarlet fever, tuberculosis or all the same helminths, the risk of developing large eosinophilia is very high.

What measures to take

The first step is to take a closer look at your child. If there are no external manifestations of the disease, the child feels great, and he is not worried about anything, then a second blood test should be taken. Perhaps at the time of delivery elevated eosinophils in the child were caused not by eosinophilia, but by something completely different. Only identifying the true cause will help solve the problem.

Whatever it was, but the disease is easier to prevent than to cure. Timely examination and respect to the health of the child will be the key to a happy childhood.

Eosinophils are granulocytic leukocytes that are characterized by good absorption of the eosin dye used during laboratory research... These are binucleated cells that can fall outside the vascular walls, penetrate into tissues and accumulate in the area of inflammatory foci or lesions. Eosinophils remain in the general bloodstream for about 60 minutes, after which they move to the tissue area.

An increase in the concentration of eosinophils is called eosinophilia. This condition is not an independent disease, but a manifestation indicating the pathology of an infectious, allergic, autoimmune origin. Detection of persistent eosinophilia may indicate allergic reaction, damage by worms, the development of acute leukemia.

In this article, we will analyze what the increased level of eosinophils in the blood of a child means.

Eosinophils in children: what is the norm and what is the deviation?

Options for the percentage of eosinophils, depending on the age of the child:

During the first 14 days of life - up to 6%.
14 days -12 months - up to 6%.
12 months-24 months - up to 7%.
2-5 years - up to 6%.
More than 5 years - up to 5%.

If there is an excess of indicators, then we can talk about the development of mild, moderate or severe eosinophilia.

In some cases, for precise definition required cells a control blood test is required. This is due to the fact that the eosin dye has the ability to stain not only eosinophils, but also neutrophils. In this case, there is a decrease in neutrophil counts and an increase in eosinophils.

Eosinophils in a child are increased: causes

A similar condition can be detected if a blood test is taken from a small, premature baby. Over time, the child grows, develops, forms it the immune system and the quantitative content of eosinophils returns to normal. In other children, the onset of eosinophilia is influenced by the development of:

Bronchial asthma is accompanied by an often disturbing dry cough that does not respond standard schemes therapy. At night, asthma attacks may occur.

An increase in eosinophils in a child can also be observed against the background of exposure to a number of hereditary pathologies: for example, familial histiocytosis.

The development of eosinophilia depending on the age of the child

The reasons for the development of eosinophilia in children under one year are most often:

Atopic dermatitis.
Development of serum sickness
Pemphigus of newborns.
Staphylococcal sepsis and enterocolitis.
Rhesus conflicts.
Development of hemolytic disease.

In children over 12 months of age, the cause of the disorder is:

Allergic reactions to certain groups of medicines.
Development of Quincke's edema.
Atopic dermatitis.

Children over 3 years of age are also prone to eosinophilia, which is caused by:

Helminthic invasions.
Skin allergies.
Development of allergic rhinitis.
Infectious diseases: development chickenpox, scarlet fever.
Oncohematology.
Bronchial asthma.

Depending on the exact reason provoking violations, additional consultation with an infectious disease doctor, pulmonologist, immunologist, allergist may be required.

Eosinophilia symptoms

The manifestations of eosinophilia depend on the underlying disease.

Helminthic invasion is accompanied by an increase lymph nodes as well as the liver and spleen; manifestations of general intoxication in the form of weakness, nausea, appetite disorders, headache, fever, dizziness; increased heart rate, swelling of the eyelids and face, the formation of a rash on the skin.
For allergic and skin diseases there is the development of itching of the skin, dry skin, the formation of wetness. In severe cases, the epidermis exfoliates and can be observed ulcerative lesions skin.

Autoimmune diseases can be accompanied by weight loss, painful sensations in the area of joints, anemia, fever.

Diagnostics

An accurate diagnosis requires comprehensive diagnostics which includes:

If necessary, an X-ray of the lungs, a puncture of the joints, and a bronchoscopy are additionally prescribed.

Treatment

Eosinophilia therapy begins with the elimination of the underlying factor that provokes such a violation. Depending on the form of pathology, as well as its manifestations and individual characteristics an appropriate treatment regimen will be selected. In some cases, it can be recommended to cancel the use of drugs that were prescribed earlier.
