Segmented neutrophils in children. The norm and possible deviations of segmented neutrophils in infants

It is very important to monitor the health of the child through regular blood tests. All indicators should be within certain limits, while deviations can indicate as yet imperceptible inflammatory processes. A special role in determining the health of the baby is played by neutrophils, which are a type of leukocyte. These cells are divided into several types, and the meaning of each of them carries certain information.

The health status of the child is monitored using a blood test, the value of the indicators of which parents need to know

Functions of neutrophils

All neutrophils that are found in peripheral blood are divided into three groups. Each of them is characterized by the degree of maturity of these particles:

The youngest cells are called myelocytes or metamyelocytes.
Cells of medium maturity - stab. Their core is not divided, it is elongated and twisted. Doctors call these particles sticks.
Fully mature cells are segmented. This name indicates that the nucleus of mature cells is segmented.

Neutrophils help the body defend itself against infections. Their main task is to capture and absorb solid particles. This function is extremely important for the body and is called phagocytosis. In the process of absorption of a solid particle, neutrophils die, but before that they have time to release a special substance. This compound attacks the foreign body and activates the inflammatory process. By this they attract other immunity cells to the battlefield.

After death, neutrophils, together with tissue particles affected by inflammation and foreign substances that caused it, form pus. If the content of neutrophils in the blood is normal, then the child's immunity is working without failure. Sometimes the level of these cells is increased or decreased, which may indicate a disease.

Neutrophils are an important component of the blood, their level shows the body's ability to resist diseases.

How to pass the analysis?

The doctor may give a referral for a blood test to determine the number of neutrophils if the child has a suspicion of a viral, bacterial infection. Children after rotavirus infection, as well as those who are diagnosed with anemia, need such a study. In addition, a detailed blood test may be planned.

Blood for research is taken from a finger. In order for the result to be correct, you need to pass it by following the recommendations:

Blood must be donated on an empty stomach. It is known that after breakfast the number of neutrophils can increase. This rule also applies to infants; you can feed a child only two hours before blood sampling.
Before passing the analysis, you should not actively engage in physical education, it is enough to do a couple of light exercises. If the child is upset about something or is in a stressful situation, it is better to donate blood another time.
Temperature fluctuations can also adversely affect the results of research. You should not immediately go into the laboratory assistant's office from the cold. It is better to sit with the baby in the hallway for 5-10 minutes before blood sampling in order to level the temperature difference and allow the body to adapt.

It is better to take the test in the morning before breakfast, so that the blood counts are the most accurate.

Normal values

The count of neutrophils is made in the process of compiling the leukocyte formula. The laboratory assistant will stain the sample and make a smear. Then it will calculate the total number of these cells, as well as their relative index. The first option is less significant, the second is considered the most important and is defined as the percentage of "rods" and segmented particles in the total volume of leukocytes. Before you start deciphering the results of the study, you should find out the tabular values. The norm for children depends on the age of the patient.

As can be seen from the table, the percentage of neutrophils differs significantly in babies up to one month from older children. Cells of medium maturity - stab - in the leukocyte formula of a newborn can take up to 17%. Whereas after a month their rate is up to 4-5%.

When neutrophils are elevated

If a child's blood test shows high neutrophils, the condition is called neutrophilia and can be due to a variety of factors. For example, if the increase is insignificant, it is likely that this is the body's reaction to the activity of the baby - he ran or played merrily before taking blood. When neutrophils are elevated at times, the doctor will recommend an examination. Diseases and other factors that can cause an increase in neutrophils:

leukemia;
vaccination;
peritonitis;
pneumonia, otitis, sepsis, bronchitis, tonsillitis;
burns of the third and fourth degrees;
abscesses;
hemolytic anemia;
diabetes;
trophic ulcers.

In case of deviation of blood counts from the norm, the doctor prescribes an examination of the child to identify the reasons for the decrease in neutrophils.

Also, neutrophils can be elevated against the background of a strong cough that occurred during SARS. This may indicate a bacterial infection that should be treated with antibiotics.

Experts say that the degree of increase in the number of these cells depends on the strength inflammatory process. In this regard, with a significant increase in the level of neutrophils, you should try to go through all the examinations prescribed by the doctor so that he can make a diagnosis as soon as possible. As a rule, treatment should be started immediately.

Sometimes blood tests show a shift in the leukocyte formula - when the overall level of leukocytes is normal, and the number of segmented cells is much higher than normal. This pattern is observed in some diseases:

infectious diseases that are asymptomatic;
inflammatory processes in acute form;
various types of tumors.

As you can see, with any deviations in the blood test, it is worth examining the child immediately. The sooner the diagnosis is made and therapy is started, the easier it is to cure the disease.

Note that elevated level these cells may have quite healthy child. It is believed that the increase in neutrophils to 7-8 * 10⁹ / l is moderate and may indicate that the baby has recently been ill, or had a hearty breakfast before blood sampling.

You may need to take additional tests, such as urine, to determine the disease

Neutrophils are below normal

Sometimes there are cases when the number of neutrophils is less than normal. This condition is called neutropenia, and it indicates a decrease in immunity. Neutropenia is diagnosed if the number of neutrophils is less than 1.6*10⁹/l. Why are there not enough of these cells in the child's blood? There may be several reasons for this phenomenon, among them:

neutrophils are destroyed by themselves;
these particles are produced in insufficient quantities;
irrationally distributed in the blood.

What can lead to the destruction or insufficient production of neutrophils? As a rule, this result is due to:

viral diseases: SARS, measles, influenza, hepatitis, rubella, scarlet fever;
fungal infections;
condition after anaphylactic shock;
acute leukemia (see also:);
intoxication with chemical compounds;
thyrotoxicosis;
the consequences of exposure;
anemia of various etiologies;
lack of vitamin B12 and folic acid;
congenital neutropenia is a fairly rare disease.

Also, the level of neutophils in children is affected by the intake of certain drugs. For example, glucocorticosteroids, anticonvulsants, and different kinds pain medications.

A decrease in neutrophils in the blood may indicate a child’s illness, such as anemia

Sometimes in babies of the first year of life, the number of neutrophils is reduced, while such a distribution of blood cells does not affect the well-being of the crumbs. Usually the pediatrician recommends to be tested again after a while. If the results remain the same, the doctor is likely to diagnose benign childhood neutropenia. To date, the causes of this disease are not known, but it does not require treatment. As a rule, the level of these particles normalizes on its own. This can happen by the year, or maybe by 2. Such a child is registered with a gemologist, immunologist and pediatrician.

A similar pathology occurs in adults, but it is called cyclic neutropenia. The essence of the disease is that the level of this type of cells regularly drops in the patient, then it is restored. The cycle can be a month, or maybe a year.

Leukocyte formula. How to figure it out?

Only a specialist can correctly interpret the results of a leukogram. If segmented nuclear particles predominate in the blood formula, they speak of a shift to the right. If stab are enlarged - to the left. A shift to the left, that is, the predominance of immature particles, may indicate a severe form of inflammation, as well as the presence of a tumor. A shift to the right may indicate:

violations of the liver, kidneys;
radiation sickness;
anemia.

The leukocyte formula shows the percentage different types leukocytes

However, during the decoding of the test results, the doctor must take into account other indicators, considering them comprehensively. For example, low neutrophils combined with elevated lymphocytes may indicate that the disease is already fading away. If neutrophils and lymphocytes are low, or the latter are normal, this may mean that the baby has a chronic process (we recommend reading:). In addition, he has a weakened immune system, which gives reason to assume frequent illnesses of the patient.

What to do if the analysis is not normal?

To date, does not exist simple ways change the ratio of certain cells of the leukocyte series in the blood. The doctor must find out the reasons for the deviation and try to adjust the blood count by indirect methods. If the root of the problem lies in taking medications, they should be removed or replaced. Sometimes the situation can be corrected by eating foods rich in B vitamins (B9 and B12).

Neutrophils in the blood of a baby may not correspond to the norm for various reasons (for more details, see the article:). The result of the analysis cannot become the main diagnostic tool. The doctor must also evaluate other symptoms, the results of examinations, in order to make a diagnosis. However, deviations in the blood count should not be ignored, so as not to miss the first signs of inflammation or any disease.

What are neutrophils and how can one judge the state of health of a child by their indicators

When describing the functions of neutrophils, it is necessary to note a number of features, which are as follows:

Neutrophils act as protectors, and their main task is to destroy bacteria that are dying red blood cells. The destruction process consists in enveloping the foreign element and splitting it, during which the death of the neutrophil itself occurs, forming pus;
The life span of a neutrophil can be only a few hours, so they are constantly updated in the body, which is carried out in the human spinal cord;
From the moment of formation to death, neutrophils go through several stages, according to the number of neutrophils of a certain degree of maturity, as well as their ratio among themselves, doctors can judge the presence of an infectious disease and the degree of its development. Such a study is carried out with a general blood test and is one of the main indicators in it.

Depending on the degree of maturation, neutrophils can be called in their own way, for example, the first of those that can be found in the blood are myelocytes and metamyelocytes, these are those neutrophils that have not yet reached maturity, but with serious inflammation are ready to help the body. Then, in order of seniority, go stab neutrophils and segmented neutrophils, which, in turn, are the most mature and they are directly involved in the fight against viruses.

In the event that during a general blood test, the child has increased content neutrophils, then this condition is called neutrophilia in a child.

The norm of neutrophils in a child

It is impossible to answer exactly how many neutrophils should be in the blood of a child, because this number is influenced by various factors from the side, for example, the age of the child, his level of physical activity, the time of day when blood was taken, and whether the child took food or not before donating blood for analysis.

In general, it is worth noting that the content of such elements in the blood as neutrophils, the norm in a child should be within the following limits:

In a newborn child: stab neutrophils ranging from 5 to 12%, segmented neutrophils ranging from 50 to 70%;
At the age of up to a year: stab neutrophils ranging from 1 to 5%, segmented neutrophils ranging from 45 to 65%;
Children under 5 years of age: stab neutrophils ranging from 1 to 4%, segmented neutrophils ranging from 35 to 55%;
Children under the age of 12: stab neutrophils ranging from 1 to 4%, segmented neutrophils ranging from 40 to 60%;

In the event that neutrophils are elevated in a child or the doctor has determined, as a result of a blood test, low neutrophils in the blood of a child, then it is necessary to conduct, first of all, a second blood test to identify the causes of the deviation.

An increase in neutrophils in the blood

The reasons that can cause an increase in neutrophils in the blood may be:

The presence in the child's body of infections accompanied by inflammatory processes. They can be either localized (for example, angina, pneumonia, etc.) or generalized (for example, scarlet fever, sepsis, etc.);
A recent illness in a child;
The development of necrotic processes, such as burns or gangrene;
recent vaccination of the child;
Intoxication, such as alcohol or chemical, for example, when exposed to lead fumes;
A decaying malignant tumor in the body.

A slight increase in neutrophils, relative to the norm, with a general blood test and the child's normal state of health can be an indicator of a recent physical or mental stress, so you should not worry in such cases.

Decrease in neutrophils in the blood

Among the reasons that can cause a decrease in neutrophils in the blood of a child, it is worth noting such as:

Genetic features of the organism;

Repeated stressful situations;

Lack of certain vitamins in the body of a child, especially vitamin B.

Also, the reason for the decrease in the level of neutrophils can be caused by a developing disease or the presence of an infection in the body. These can be diseases such as rubella, hepatitis, influenza and chickenpox.

It is worth noting that only a doctor can make a diagnosis and identify the reason why the level of neutrophils has decreased, since this can be caused by a bone marrow disease in a child.

segmented neutrophils

Segmented neutrophils are directly involved in the fight against bacteria and can independently move to the site of inflammation, while dying, they release a substance into the blood that attracts other segmented neutrophils to this place. At the same time, pus is formed at the site of inflammation, which is these very dead cells.

The presence of infection is determined by the number of these cells. The number of elements such as segmented neutrophils, the norm in children should be within certain limits, which we described earlier.

In the case when segmented neutrophils are lowered in a child, this condition is called neutropenia. This may be a temporary phenomenon, or it may be caused by the following reasons, which are:

In diseases of the blood and bone marrow;
The case of the use of chemotherapy in the treatment of cancer;
Treating a child with antiviral agents;
The impact on the body of a viral infection;
Manifested allergies.

When segmented neutrophils are elevated in a child, this phenomenon is called neutrophilia. It can be caused by the following reasons:

In connection with infection with an acute bacterial infection;
In case of recent vaccination in a child;
With pronounced alcohol intoxication;
With kidney damage, including diabetic nephropathy.

Stab neutrophils

Stab neutrophils are an immature type of neutrophils, which, as a rule, do not exceed 30% of the total composition of neutrophils in the blood.

What does such a concept as segmented neutrophils mean, and what is their norm in children? This indicator indicates the state of humoral and tissue immunity of the child. In adults and in children, the segments perform the same function - they protect the body. To determine the state of the immune system, as well as to identify various kinds of diseases in time, it is necessary to determine the level of segmented neutrophils using blood sampling.

What are segmented neutrophils and their functions

All neutrophils are leukocytes, that is, they are white bodies.

According to their degree of maturity, they are divided into 3 types:

myelocytes;
stab;
segmented.

Moreover, the latter type is the largest in terms of the number of cells among all leukocytes. They can occupy from 40 to 80% of the total volume. At the same time, it is these cells that play one of the main roles in protecting the body.

Neutrophils are produced by the bone marrow. Being the most mature cell, segmented neutrophils live in the blood the longest. And also they are the first to react to the penetration of harmful bacteria and pathogenic fungi into the body. Due to their ability to penetrate into the tissue through the vascular wall, the segments can actively protect the body from various diseases.

There is one point that you need to know - segmented neutrophils do not fight viruses, they are powerless against them. All other infections are attacked by these cells. They suck the bacterium into their protoplasm, where it dissolves. In this process, the protective cell dies. But the bone marrow is already producing new cells that have information about the invading bacteria.

The result of an analysis for segmented neutrophils in a child can indicate diseases that are in the body and begin their timely treatment.

Norm indicators in children

The norm (and segments in the blood in children is not an exception at all) is determined using a general analysis with detailed leukocyte counts.

Therefore, you need to prepare the child according to the recommended rules:

It is necessary to take the analysis on an empty stomach in the morning.
You can drink only water before taking blood. Tea, coffee and juices should not be consumed.
It is not recommended to do the analysis if the child is taking medications.
A few days before donating blood, it is better to exclude fatty and fried foods from the diet.

Normal values may vary depending on the age of the child:

The indicators will normally change up to 12-15 years. After that, the level of segmented neutrophils will become the same as in adults. The deviation from the norm can be both up and down.

After deciphering the analysis, when determining deviations from the norm, the child's attending physician must identify the cause of the decrease or increase in the level of segmented neutrophils.

Why cell levels are dropping

When a blood test over several samples shows a low level of segmented neutrophils, this may be a consequence of the virus entering the body.

In children, this reaction most often occurs with such ailments:

rubella;
chicken pox;
measles;
flu.

And also diseases that are caused by bacteria, such as tuberculosis or typhoid fever, can also affect the decrease in the level of protective cells. A low level of cells is also found in anemia, severe fungal infections.

But, in addition to diseases, a decrease in the level of mature neutrophils can be triggered by emotional and physical stress. stressful situations, fatigue, poor sleep often become the causes of the development of neutropenia. Children under 3 years of age may have chronic benign neutropenia. In these situations, it passes on its own.

Treatment in case of a low level of cells is more directed not to increase their number, but to destroy the virus that provoked the disease. And start effective treatment needed as soon as possible.

A low level of mature neutrophils seriously weakens the body's immune defenses. This is especially dangerous for newly born children. The immunity of the newborn itself is weak, and a small number of segmented neutrophils significantly increases the infection of the child. There is a rare genetic disease, in which this type of cell in the body is absent altogether. With such a diagnosis, maximum attention should be paid to the health of the baby, since any infection will affect him more often than other children.

A low level of analysis can show if the principles of preparation for it have been violated. In this case, the doctor asks to repeat the blood sampling, and the primary result will be considered false.

Causes of increased cell levels

As in the case of a decrease, so in the case of cell growth, this is a bad signal for the body. It seems that the growth of segmented neutrophils should serve as a good indicator, because this means that the body's immune defense is coping with its functions. But actually it is not. Neutrophilia, or an elevated level of neutrophils, is caused by a variety of serious causes.

The most common are bacterial diseases, these include:

angina;
pneumonia;
inflammatory processes;
acute appendicitis.

And also an increase can cause peritonitis or sepsis. Hemolytic anemia or leukemia in complicated forms also provokes an increase in the level of protective cells. In children, burns or purulent formations can provoke a deviation from the norm of neutrophils upwards.

If the blood test for segments differs from the norm, then you should not delay treatment, you should immediately contact your doctor. In this case, the result of the analysis may indicate a disease that is almost asymptomatic in the body of the baby. The sooner it is detected, the more painless and effective the course of treatment will be.

They are one of the types of leukocytes. Neutrophils also protect the body from harmful microbes, fungal and bacterial infections. These are the first cells designed to meet aggressive provocateurs of inflammatory processes and resist their effects.

In addition, they are a kind of orderlies that absorb old blood cells and dead cells, which contributes to the rapid healing of wounds. Being an important element of immunity, they show high activity at the initial stage of inflammatory formations.

A reduced content of neutrophils indicates the presence of an infectious disease, leads to a weakening of the body's defenses and the growth of manifestations of the disease. If a decrease is diagnosed, it can be considered a signal for a thorough diagnostic examination, as this may indicate the presence of serious diseases.

Varieties of these cells

Neutrophils differ from leukocytes in granularity, which gives reason to classify them as granulocytes, as well as in color neutrality.

Neutrophils are divided into mature and immature.

The nucleus of mature cells can consist of several segments, so they are called segmented. Young (or immature) resemble a stick, as a result of which they are called stab.

Causes and types

The decrease in neutrophils by the duration of the process can be acute and chronic. In the first case, the time period is less than 3 months, and in the second - more than 3 months. The causes of neutropenia are divided into 3 main groups:

internal, associated with reduced bone marrow activity or autoimmune destruction of white cells;
external, caused by external factors (infections, intake medicines etc.);
low neutrophil count as a manifestation of a hereditary syndrome (Kostman's syndrome, Barth's, etc.).

Diseases leading to neutropenia:

Causes of neutrophilia

Studies of blood leukocytes made it possible to identify their varieties, which differ not only in affinity for dyes and in appearance, but also perform different tasks. Segmented neutrophils are the most large group cells among leukocytes. Based on the principle of the rational structure of the body, one can guess that they have the most significant role.

Structure

According to their structure, leukocytes are divided into granulocytes, which have dotted granules in the plasma, and agranulocytes, without additional inclusions. Unlike red blood cells and platelets, these cells are endowed with a nucleus and are able to exit blood vessels and move to inflamed tissues.

Granulocytes differ in their Romanowsky staining for basophils, eosinophils, and neutrophils.

The group of neutrophils is also not homogeneous: according to the shape of the nucleus, they are divided into segmented (the nucleus is divided into parts by constrictions) and stab (the nucleus looks like an elongated ball).

A reduced number of neutrophils or neutropenia can indicate a blood disease or when there is an inflammatory process in the body. You can determine neutropenia using a detailed blood test, so you can find out if neutrophils in the blood are lowered or not.

Neutrophils are blood cells produced in the bone marrow that protect the body from harmful bacteria, fungi, and viruses. When foreign substances enter the body, it begins to react with an increased number of neutrophils.

Types of neutrophils

1. Band-nuclear, young, they have a solid and rod-shaped nucleus.

2. A segmented and formed nucleus has segmented and mature neutrophils.

What is the norm of neutrophils?

The level of neutrophils in the blood directly depends on the age of the person. In children under one year old, neutrophils make up from 30% to 50% of leukocytes, when a child grows, his level of neutrophils begins to increase, at seven years the number should be from 35% to 55%. In adults, the norm can range from 45% to 70%. In cases of deviation from the norm, when the indicator is lower, we can talk about a reduced level of neutrophils.

What are the types of low neutrophils?

1. Congenital neutropenia.

2. Acquired neutropenia.

3. Unexplained neutropenia.

Often in children under 2 or 3 years of age, neutropenia is chronic and benign, then the indicators may return to normal.

There are situations when segmented neutrophils are normal, then lowered again. Then we can talk about the cyclicity of neutropenia.

Causes of low neutrophils, their treatment

It should be noted that the level of neutrophils directly depends on the cause - the stronger the effect on the child's body, the higher such leukocytes will be.

A slight increase in the percentage of neutrophils occurs during physical or psycho-emotional stress, as well as after eating. If the reason for the high number of neutrophils is some kind of disease, then the level of cells is directly related to the activity of the disease.

The pathological causes of neutrophilia include:

Active inflammatory processes, such as arthritis, pneumonia, dermatitis, inflammation of the pancreas, appendicitis and others.
Bacterial infections, including purulent (formation of an abscess or phlegmon).
Some viral infections.
Infections caused by protozoa or fungi.
tumor processes.
Extensive burns.
Poisoning.
Diabetes.
Trophic ulcer.
The use of certain medications, such as corticosteroids.
Acute blood loss or hemolysis of red blood cells.

Also, neutrophils are found in increased numbers in postoperative period.

If the level of neutrophils in children exceeds the norm slightly, most likely there is no cause for concern. This condition can be observed after physical activity.

If there is a significant and persistent increase, then the child must be examined. The reasons may be different, including acute processes, malignant tumors, tissue necrosis. You can read about the reasons for the increase in the level of neutrophils in adults here.

Usually neutrophilia is explained by the following diseases:

hemolytic anemia;
leukemia;
abscesses;
appendicitis;
diabetes;
acute inflammatory diseases such as tonsillitis, pneumonia, otitis, sepsis, peritonitis, bronchitis, and the like;
trophic ulcers;
severe burns (third and fourth).

The level of these cells directly depends on the intensity of the flow pathological process. If neutrophils are significantly elevated, rapid diagnosis and timely treatment are needed.

An increase in neutrophils in the blood of a child is observed in many diseases. A thorough examination is required to determine the cause.

The total number of neutrophils in a child may be normal, but the segmented forms are increased, that is, there is a shift of the leukogram to the right. This may indicate the following processes in the body:

infectious diseases, sometimes occurring without clinical manifestations;
acute inflammation;
tumors (benign and malignant).

The condition when neutrophils exceed the upper limit of normal values is called neutrophilia. It is important to understand that such an increase occurs due to stab cells, and segmented neutrophils are slightly increased.

There are two types of neutrophilia - physiological and pathological.

Physiological neutrophilia is the response of a healthy body to the action of one or another factor that does not belong to the signs or links of any pathogenesis of diseases.

The list of such reasons includes:

hereditary factors;
impact on the body of extremely high or low temperatures, as well as solar radiation;
sharp emotional stress, anxiety states;
severe vomiting;
pain syndrome;
excessive physical exercise;
hemolysis;
in women - ovulation, a change in the phases of the menstrual cycle, acute blood loss during critical days, pregnancy, childbirth;
the child has increased physical activity.

Pathological neutrophilia is a condition caused by various diseases.

The immediate causes of neutrophilia are:

Increased production of neutrophilic cells in the bone marrow.
Reducing the exit of segmented neutrophils from the bloodstream into the tissues.
A simultaneous increase in the number of neutrophils circulating in the blood and a decrease in parietal (marginal pool) neutrophil cells - pseudoneutrophilia. For example, with convulsive syndromes.

These mechanisms of development can act both separately and simultaneously.

The most common causes of prolonged neutrophilia are acute infections of bacterial etiology, as well as some pathogenic fungi and viruses. However, any acute inflammation or exacerbation of a chronic one can cause an increase in neutrophilic leukocytes.

Other common diseases or factors that cause an increase in the number of neutrophils include:

food poisoning, such as salmonella;
poisoning by insects or snakes;
toxic poisoning of the bone marrow with toxic substances or alcohol;
long-term use of certain medications;
individual reaction to certain drugs;
uremia;
jaundice;
alcoholic cirrhosis liver;
diabetic ketoacidosis and coma;
in women - toxicosis during pregnancy.

Elevated segmented neutrophils in a child usually indicate angina, pneumonia, otitis media, inflammation of appendicitis, or the presence of abscesses.

Parents should pay attention to the fact that the child does not rub his fingers before the analysis. Such nervous rubbing leads to a distortion of the results in the direction of increase.

If the stimulus for increasing the content of neutrophilic leukocytes is a malignant uncontrolled growth in the number of cells, then neutrophilia becomes chronic. For example, in sickle cell anemia, high levels of neutrophils persist throughout life.

Symptoms and laboratory diagnosis

The condition in which low neutrophils are noted in a child or adult is called "neutropenia". Its clinical manifestations can be observed in the form of purulent tonsillitis, stomatitis, cystitis, as well as an asymptomatic inflammatory process, as a result of which osteomyelitis may develop.

Symptoms appear depending on what caused the neutropenia. In some cases, these are simple, at first glance, symptoms:

general weakness;
fatigue;
sweating;
tendency to frequent colds.

More serious symptoms indicating a decrease in the level of neutrophils are the presence of stomatitis, periodontal disease, and numerous inflammatory formations on the skin in the form of pustules.

In complicated situations, there may be an increase in temperature and a feverish state.

The asymptomatic course of neutropenia in infants is not considered a pathological disease, since by the age of three the number of neutrophils usually normalizes.

When neutrophils are low clinical picture is very diverse. It is characterized by the frequent development of inflammatory manifestations of various localizations along with an increase in body temperature:

stomatitis;
periodontitis;
pharyngitis;
sinusitis;
pneumonia;
colitis and others.

Against the background of a reduced level of neutrophils, the symptoms of an inflammatory reaction (pain, redness, swelling) are not pronounced, and may be absent altogether. Therefore, these children require constant clinical monitoring.

Hematological combinations of neutropenia can be very different. So, in the general blood test are determined:

neutrophils are lowered, and lymphocytes are increased in a child (most often this symptom is observed in tuberculosis);
monocytosis (with infectious mononucleosis);
neutrophils are lowered and lymphocytes are lowered in a child (with prolonged viral infections);
moderate eosinophilia (with allergic diseases) etc.

What to do when a child has a decrease in segmented and stab leukocytes? First, it is necessary to re-conduct a repeated general clinical blood test. It is recommended to do this monthly for 3 months. If the diagnosis of neutropenia is confirmed, then it is shown to find out its cause. For this purpose, a more detailed clinical, laboratory and instrumental examination is carried out:

bone marrow puncture to exclude myeloid leukemia and suppression of the leukocyte germ of hematopoiesis;
chromosomal analysis of bone marrow cells
determination of antineutrophil antibodies in the blood;
molecular genetic examination;
detection of infections by PCR;
determination of the concentration of cyanocobalamin and folic acid in the blood;
specific autoimmune tests.

Principles of treatment

When confirming the fact of a decrease in neutrophils, a thorough laboratory and instrumental examination of all body systems will be required, the purpose of which is to identify the causes that provoked pathological changes. Only after that, the doctor will be able to prescribe adequate treatment that promotes an increase in neutrophils.

It is important to know that treatment is always aimed at eliminating the causative factors that were the prerequisite for neutropenia. Due to the correctly chosen course of treatment based on the identified reasons, it is not difficult to bring the indicators back to normal. For example, after suffering infectious diseases, they recover on their own.

An important point in the treatment of neutropenia is to increase the immunity of the child. For this purpose, it is recommended to take a vitamin course, improve nutrition, and temporarily limit physical activity.

If there are manifestations of stomatitis, gingivitis, the doctor will advise regular rinsing with decoctions of various herbs that have antiseptic properties. These include St. John's wort, chamomile. The pharmaceutical drug Rotokan has proven itself well.

In some cases, therapeutic drug treatment may be used. This treatment is advisable for progressive neutropenia. The use of drugs such as Methyluracil, Pentoxyl, provides for a consultation with an immunologist and an immunogram.

With a steady decrease in neutrophils, it is possible to use Filgrastim, Lenograstim. These are powerful drugs large quantity side effects, therefore, their appointment is permissible only for inpatient treatment under the supervision of experienced professionals.

Treatment of isolated neutropenia depends on the severity of the infection. With a mild to moderate decrease in granulocytes, the risk of infectious diseases is minimal, therefore, they adhere to expectant tactics. Usually, neutropenia resolves on its own. In severe form and fever, hospitalization and antibiotics are indicated. These drugs must necessarily affect the anaerobic flora.

The introduction of granulocyte colony-stimulating factor is indicated only when the level of neutrophils is less than 0.2∙10⁹/l. This drug affects the bone marrow, increasing its functional activity.

As a result, this makes it possible to achieve sufficient anti-infective protection, which is possible with a granulocyte count of 1∙10⁹/l or more. The effectiveness of the colony-stimulating factor has been proven in randomized trials.

However, its long-term use increases the risk of acute myelogenous leukemia. Therefore, it is important to identify the causes of neutropenia and eliminate them.

Control over the composition of the blood is important at any age. Parents should be especially careful. After all, hardly any of them would not want their baby not to get sick and be happy.

The results of the analyzes are carefully studied by a specialist. If all blood counts are normal, then the little person is in good health. Any deviation prompts the doctor to conduct additional tests.

Data on the level of neutrophils are necessarily reflected in the leukocyte blood count, because these cells are a type of white blood cells. Neutrophils, or neutrophilic granulocytes, are a significant component of leukocytes. In the immature state, their share reaches 75% of all white cells.

When the level of neutrophils is in the established range, then this is evidence of the satisfactory functioning of the baby's immune system. It effectively resists viruses and bacteria that periodically penetrate the child's body.

The role of neutrophils in the child's body

The production of neutrophils occurs in the red bone marrow, an important organ of hematopoiesis and immunopoiesis. After leaving it, the cells move for several hours as part of the peripheral blood. They then migrate to the tissues and may remain there for some time.

A characteristic feature of newly formed cells is the presence of granularity (granules) in their internal environment. Neutrophil granules contain antibacterial agents, thanks to which the cells are able to perform the following functions:

protect the baby's body from infection. Neutrophils are the first to meet microbes, bacteria, viruses and take a hit, trying to quickly destroy intruders;
capture and absorb solid foreign particles, dead cells, neutralize and remove them to the outside. Neutrophils are classical phagocytes. And here the decisive role is played by the fact that they are very mobile and able to penetrate without any obstacles into the most remote corners of the baby's body. Cells do not move randomly, but towards the site of tissue damage or the inflammatory process.

Cells circulate in the blood in two varieties:

Stab (not yet mature).
Segmented (have reached maturity).

A significant number of immature neutrophils are present in the blood of crumbs that have just been born. Then their number and share gradually decrease. They give way to mature cells, which are able to protect the baby from harmful bacteria penetrating from the external environment.

The optimal level of neutrophils guarantees the body strong immunity.

The norm in children

The child's body needs increased protection. Therefore, the ratio of individual groups of leukocytes differs from the norms established for men and women.

The level of neutrophils is measured as a percentage. Its optimal value does not depend on the sex of the baby, but changes with age. The content of both types of neutrophils is necessarily determined:

stab;
segmented.

The norms of neutrophils for children of different ages are as follows:

The absolute number of neutrophils gradually decreases, although the lower limit of normal increases slightly.

In a newborn, the level of mature cells is quite high and can reach 80%. The proportion of stab neutrophils is also significant - up to 17%. But after the baby is one year old, the concentration of both types of cells gradually decreases and at the age of 15 it becomes equal to the norm for adults.

When the need arises, a detailed blood test is performed. It allows you to determine the presence of young neutrophils called myelocytes and metamyelocytes. These cells normally should not be in the blood. But if they are still fixed, this means that the body is conducting a serious fight against the disease, activating all its reserves.

Elevated neutrophils

A slight increase in the level of neutrophils (neutrophilia, or neutrophilia) may be temporary. Cause such a phenomenon in a state of physical activity and negative emotions. If other indicators of the blood composition are without deviations, you should not worry.

When there is a persistent and significant increase in the level of not only neutrophils, but also leukocytes in general, one cannot do without an additional examination. After all, there can be many reasons for neutrophilia, and many of them are quite dangerous.

Possible ailments are:

Acute inflammatory diseases: otitis and tonsillitis, pneumonia, appendicitis and peritonitis, abscess and sepsis.
Tissue necrosis, the development of which is caused by: a burn that covered a large part of the body; tropical ulcer.
hemolytic anemia.
Leukemia.
Diabetes.

There are situations when the level of only segmented neutrophils rises. This phenomenon is called neutrophilic leukocytosis. It can indicate the following processes:

the development of infectious diseases that do not manifest clinical symptoms;
acute inflammation;
benign and malignant neoplasms.

How high the level of neutrophils has risen depends on the intensity of the development of the pathology. Their significant upward leap requires immediate examination of the child and therapy.

Neutrophils are lowered

A decrease in the level of neutrophils compared to the norm is called neutropenia. Its development in a baby is evidence of a weakening of the immune defense. Neutropenia may occur due to increased cell destruction, insufficient production (division) or improper distribution in the body.

The main reasons for the decrease in the level of neutrophils:

Recent illness.
Malfunctions in the functioning of the bone marrow: neutrophils die, and the process of their production is disrupted.

Neutrophilic granulocytes can decrease both quantitatively and in percentage terms. This happens with the development of such ailments:

Diseases caused by viruses: SARS and influenza, measles and rubella, hepatitis.
Anemia: megaloblastic and iron deficiency, aplastic and hypoplastic.
Fungal infections.
Diseases of the thyroid gland, in particular thyrotoxicosis.

The level of neutrophils also decreases in the case of exposure to chemicals that enter the body through the air, drink or food.

Pain medications and seizure medications can also cause cell decline.

AT infancy Children may present with chronic benign neutropenia. The disease is accompanied by a significant drop in the level of neutrophils.

The illness rarely lasts more than two years. It does not affect the well-being of the baby and does not manifest characteristic symptoms. The disease is not treated and goes away on its own.

If the baby has a low or high level of neutrophils with normal health, and the situation does not change for a long time, then you should not worry too much. Constant monitoring of blood counts and monitoring the condition of the child will help to fix a possible pathology in time and successfully cure it.
