Lymphocytes are low, neutrophils are high: what does this mean?

Content standards

Knowing the level of lymphocytes (designated “ABC”) makes it possible to conduct a general clinical blood test. The procedure is practically painless, the material is taken in the morning on an empty stomach from a finger, heel (in a child under one year old), sometimes blood from a vein is required.

A small patient should eat in the evening, excluding spicy and fatty foods, because they can affect the result. In the morning you can only drink a little clean water. Before going to the laboratory, you should not brush your teeth; you should stop taking medications in advance or report this nuance to the medical institution.

Fasting blood tests are not performed on infants. You can take the material at any time of the day; you are allowed to feed the baby 2 hours before the procedure.

Sometimes a clinical study is carried out several times to more accurately monitor the patient's condition. In this case, blood sampling should be done at the same time.

The lower limit depends on age:

newborns - 16%;
fifth day of life - 30%;
from the tenth day - 40%
from 1 month - 45%;
over 5 years old - 35%;
over 10 years old - 30%.

If the result turns out that the percentage of lymphocytes in a child is reduced, this condition is called lymphopenia; if abs is increased, it is called lymphocytosis.

Reasons for deviations

If lymphocytes in a child’s blood are low, his immune system is not able to provide the necessary protection. The reasons for the decrease in the number of white blood cells may be pathologies of the organs that produce them or diseases.

Oncology

Malignant neoplasms can manifest themselves in different ways: increase or increase and even change the shape of the blood. Only leukemia or leukemia behaves predictably.

This family of cancers causes normal cells to be replaced with immature cells.

They are not able to perform their functions, but they take up space, which means that the actual parameters are reduced. Gradually, there are fewer and fewer mature lymphocytes, which leads to the fact that the body does not have the strength to cope even with a cold, and any infection, even ARVI, can become fatal.

Immunodeficiency conditions

These are conditions when the immune system is too weakened. There are a large number of such diseases, the most common of which are:

Bruton's disease;
antibody deficiency with normal immunoglobulin levels;
immune deficiency;
DiGeorge syndrome;
Louis-Bar syndrome;
hereditary neutropenia.

The listed immunodeficiencies are primary.

Among secondary diseases, HIV is considered the most dangerous. The virus installs its own gene code into the gene code of immune cells, and the immune system does not fight it. Over time, HIV kills large numbers of immune cells, and AIDS develops.

Ionizing radiation chemotherapy

Both causes lead to the same result: low levels of lymphocytes in the blood. Treatment with ions causes cellular mutations, due to which a large number of mature cells die. Chemotherapy destroys immature cells: both cancer and immune cells. However, the effects of chemical therapy are reversible; radiation leads to more complex problems.

Kidney and liver failure

The liver and kidneys cleanse the fluid connective tissue of toxins, excess fluid and dead cells. If the functions of one of these organs are impaired, the bloodstream becomes clogged and there is not enough space for lymphocytes, so their levels decrease.

Systemic lupus erythematosus

Most autoimmune diseases increase the activity of immune cells, but lupus is an exception. In autoimmune pathologies, the immune system recognizes its own cells as foreign and begins to eliminate them. Because of this, the level of all types of leukocytes increases. When lupus occurs, special cells appear, the food of which is other leukocytes, including lymphocytes. Because of this, there are fewer of them than normal.

Why are lymphocytes needed?

Lymphocytes play a very important role in the human body. They provide a protective function against the invasion of foreign cells. Penetrating into lesions, lymphocytes help fight various infections, viruses, and bacteria. These are the main components of the immune system; they are responsible for the production of antibodies and the immune response.

Lymphocytes

Lymphocytes, due to their structure, are able to distinguish their own cells from foreign ones. They do a great job in the body: they look for foreign cells, attack them, destroy them and then transmit information. Lymphocytes are interesting because, after penetrating the affected tissues, they are able to return to the blood and move independently.

Functions of lymphocytes

In a clinical blood test, we usually see not the absolute number of lymphocytes, but their percentage relative to leukocytes. Lymphocytes are a type of leukocyte, white blood cell. In addition to lymphocytes, leukocytes include neutrophils, eosinophils, basophils and monocytes.

Leukocytes

Types of lymphocytopenia

If a child or adult has lower than normal lymphocytes, this condition is also called lymphocytopenia.

By content

Lymphopenia can be:

relative: decrease in small cell content;
complete: reduction of a high content of lymphocytes.

These types can occur separately or together, which is more common.

By origin

There are 2 types:

congenital: present from birth;
acquired: arose in the course of life.

Congenital is observed less frequently; its cause may be a genetic predisposition or HIV infection in the mother. Congenital lymphopenia is an independent diagnosis.

According to the speed of development

According to the speed of development, pathology is of 2 types:

acute: appears suddenly, grows quickly, poses a high threat, but responds well to treatment;
chronic: develops slowly, poses a threat in the long term, is poorly controlled.

The acute stage appears after chemotherapy and ionizing radiation, with impaired renal function, and other rapidly developing diseases.

Chronic may be a sign of cancer, lupus, liver and spleen diseases.

Symptoms and signs

If a child does not have enough lymphocytes, this is not a disease, but only a reaction to pathological processes occurring in the body. For this reason, lymphopenia has no special symptoms; it can only be detected after a clinical blood test.

Since low lymphocytes in a child’s blood may be due to the presence of infections, indirect symptoms are:

feeling unwell, weakness;
frequent colds;
enlarged lymph nodes;
temperature increase.

Acute viral respiratory infections also have these signs, because with them the level of lymphocytes is always low.

In the presence of a long-term disease, a low level of this type of leukocytes is manifested by enlarged lymph nodes.

This happens because the lymph nodes are close to the site of infection. For example, with tonsillitis, bumps appear on the neck, and with otitis, the parotid lymph nodes become enlarged. The appearance of such a symptom should always be a reason to immediately contact a pediatrician.

The relationship between simultaneous changes in the level of different blood cells

In medicine, there are many cases where a change in the level of leukocytes occurs simultaneously with a disturbance in the normal number of other blood cells.

If a patient has elevated leukocytes and lymphocytes at the same time, then this phenomenon indicates a physiological process in the patient’s body. The increase in protective cells is insignificant, and the period of leukocytosis is short. A high number of leukocytes and lymphocytes during a physiological process is not a serious problem and goes away on its own.

What does a change in the level of different blood cells indicate?

No less often, the cause of increased levels of protective cells is constant stress, which provokes hormonal imbalance. More rarely, simultaneous high activity of leukocytes and lymphocytes is observed in viral pathologies or damage to the skin (you need to reduce the level of protective cells yourself, as the disease will progress).

If there is a condition in which the level of leukocytes is reduced and the level of lymphocytes is increased, then this indicates pathologies:

Leukemia.
Asthma of bronchial type.
Diseases accompanied by purulent processes.
Infectious pathologies (if untreated, one infectious formation in the body will give rise to many localized foci).

In rare cases, the level of leukocytes decreases and the level of lymphocytes increases in viral diseases. However, the level of leukocytes will not be too low, and the level of lymphocytes will not be very high, which is a characteristic difference between viral colds and severe pathologies.

Colds as a cause of an increase in lymphocytes along with a simultaneous decrease in leukocytes

Another condition can occur when neutrophils are low at the same time as lymphocytes are high. With this phenomenon, the pathologies are the same as with a reduced level of leukocytes against the background of a high level of lymphocytes:

Inflammatory diseases.
Viral pathologies.

The condition in which the neutrophils in the human body are reduced and the lymphocytes are increased is different from the condition in which the number of leukocytes in the body is reduced and the number of lymphocytes is increased. And the difference is small: in the second condition, concomitant symptoms are observed, and in the first condition they are absent.

Depending on whether the number of protective cells in the blood is increased or decreased, the doctor will make a diagnosis and prescribe a preventive course of therapy that will increase the level of certain cells. However, for such a course to be effective, it is necessary to take a blood test to determine the level of certain cells in advance.

How to treat the disorder

There are no special medications that are prescribed for low lymphocytes. For this reason, self-medication is dangerous. Only a doctor should prescribe a course of therapy, and the treatment will be comprehensive. The child will have to take vitamins, possibly medications to eliminate the root cause of lymphopenia, and also eat properly.

You can increase lymphocytes in the following ways:

walk more in the fresh air, move actively;
maintain hygiene, wash your hands and do not eat unwashed fruits and vegetables;
consume foods containing protein.

Traditional recipes:

Pollen. The preparation is mixed with liquid honey in a ratio of 2:1. You need to take the remedy 1 tsp. Once a day on an empty stomach, drink tea or milk.
Apples, cranberries and walnuts. Peel 4 apples, cut out the core, pass the fruit, 500 g of berries and 1 cup of nuts through a meat grinder, add 0.5 cups of water and sugar, put the mixture on low heat and bring to a boil. Take the product 1 tbsp. l. daily.
Fresh juices. Pomegranates, beets, carrots, cranberries and cherries increase the number of lymphocytes in the blood and strengthen the body's defenses. Juices from these vegetables, fruits and berries are recommended to be regularly included in your daily diet. Only juices should be freshly squeezed.

In special cases, immunoglobulin injections and blood transfusions may be prescribed. These procedures can only be performed in a medical facility.

Medicines

If tests show that a child has few lymphocytes, he will most likely be prescribed one of these medications:

Ascorbic acid. Ball-shaped tablets with a large amount of vitamin C in the composition.
Vitamin C effervescent tablets. The drug does not contain sugar and is more suitable for young children.
Ascovit effervescent tablets. It is similar to the previous one, but has different tastes. However, flavoring additives can cause allergies, so the drug is not suitable for everyone.

Important information: What are band neutrophils and the reasons for increased levels in adults?

Vitamin C is an essential component in the production of leukocytes, so it must be included in the treatment of leukopenia.

Corrective diet

There is no diet that specifically increases lymphocyte levels. But, as in the case of drug therapy, ascorbic acid must be present in food.

The following foods are considered more fortified:

cherry;
bell red pepper;
parsley;
rose hip;
black currant;
dill;
Brussels sprouts;
citruses;
kiwi;
onion and garlic.

At the same time, large consumption of citrus fruits can cause allergic reactions, so it is necessary to include in the child’s diet those foods that his body tolerates well.

Why are lymphocytes elevated and neutrophils decreased in adults and children?

When a blood test shows that neutrophils are low and lymphocytes are high in an adult or child, this is alarming. Therefore, many immediately begin to search on the Internet what this could mean. It should be noted that even a doctor cannot make an accurate diagnosis using these indicators alone. Therefore, if the leukocytes deviate from the norm, the doctor will order additional examinations, based on the results of which a diagnosis will be established.

Immune system cells

The most important role in human immunity is played by leukocytes, white blood cells. It is generally accepted that there are five types of white blood cells in the body, the number of which fluctuates greatly throughout life. In this case, it often happens that one type, for example, neutrophils, decreases, while another (lymphocytes) increases. This is explained by the fact that their different types carry different functional loads in the functioning of the immune system.

The level of white blood cells in a child is usually increased compared to their number in an adult. This happens because the child’s immune system has to resist various infections much more often.

The leukocyte norm in children and adults should be:

in a newborn child: from 10-22 billion per liter;
in children at six months – 9-11 billion per liter;
from one to two years – 4-12 billion per liter;
from 2 to 6 years – 4-10 billion per liter;
from 6 and older: 4-8 billion per liter.

During the examination, not only the total number of leukocytes is studied, but also their ratio to each other. Particular attention is paid to lymphocytes and neutrophils.

The Neutrophil Challenge

Neutrophils are the most common type of white blood cell. They have a short lifespan (from 5 to 90 hours) and have the ability to penetrate body tissues better than other white blood cells. The reason for this is the activity of these cells and their small size.

Neutrophils instantly respond to signals of inflammation in the body and are sent through the blood vessels to its source. If the infection is too severe, they die and form pus, attracting other types of white blood cells. Neutrophils also secrete various antibacterial substances and enzymes.

This type of immune system cells is usually divided into band and segmented cells. Segmented neutrophils have the main function in the immune system, since they have a greater ability than band neutrophils for phagocytosis, that is, to absorb and dissolve pathogenic microorganisms and particles.

In a newborn child, the number of band neutrophils ranges from 5 to 12% of the total number of leukocytes.

Then their number decreases and fluctuates between 1 and 5%. Segmented neutrophils are of greater importance in the functioning of the child’s immune system. In children from one to six years of age, the proportion of segmented cells ranges from 50 to 70%, then decreases and in an adult it remains in the range of 40-60%.

Lymphocyte work

The task of lymphocytes is to recognize foreign elements and neutralize them with the help of antibodies and cytotoxins. Their number in a child’s immune system is twice that of an adult. The reason for this is that lymphocytes perform a unique adaptive function in the immune system, and the child’s immunity adapts to the environment.

Lymphocytes are divided into three main categories:

t-lymphocytes - produce thymus or thymus cells, perform auxiliary functions, synthesizing signal substances and cytotoxins;
b-lymphocytes - produce bone marrow cells, perform the main immune function, producing antibodies.
natural killers.

After meeting a pathological agent, t- and b-lymphocytes are activated. Their structure contains special memory cells that encode entire lists of antigens, making vaccination successful. Therefore, even after a long time, they are able to instantly respond to pathogens that have already penetrated the body.

Killer cells are part of the innate immune system. They release cytotoxins towards infected and modified cells (eg tumors).

Features of the analysis

Doctors advise taking a general blood test annually for timely detection of pathological processes. An analysis is also prescribed if the patient complains of certain symptoms (pain, temperature, etc.).

A white blood cell count can reveal hidden infections and guide the doctor on what type of examination to prescribe. This is especially important for identifying diseases that are difficult to diagnose (autoimmune diseases, immunodeficiencies, blood diseases). Also, deciphering the analysis helps to monitor the effectiveness of chemotherapy and radiation therapy for cancer patients.

The blood test procedure involves taking a blood sample from a finger or a vein in the arm. The material collection procedure generally proceeds without problems. But sometimes complications are possible when the specialist is unable to determine the location of the vein or the needle gets stuck in the tissue.

Data interpretation

Depending on whether leukocytes, neutrophils and lymphocytes are increased or decreased, the cause of the disease is determined by a blood test. The algorithm is as follows:

Acute viral infection – leukocytes are increased, lymphocytes are increased, neutrophils are decreased.

Chronic viral infection - leukocytes are normal or low, lymphocytes are at the upper limit of normal or high, neutrophils are at the lower limit of normal or low.

Acute bacterial infection – leukocytes are increased, neutrophils are increased, lymphocytes are decreased.

Chronic or local bacterial infection - the same signs as for acute, but to a lesser extent, closer to normal.

As can be seen from the above formula, lymphocytes react primarily to viruses, and neutrophils - to bacteria. It is worth noting that bacteria are a much more complex biological formation than viruses. As living beings, they have their own DNA and have the ability to reproduce. While the virus is only capable of parasitizing the body of the host cell in which it produces its copies.

The most common viral infections are influenza virus, herpes, hepatitis, measles, rubella, encephalitis and others. Among the bacterial diseases we list such as diphtheria, tetanus, tuberculosis, E. coli, syphilis and others.

Diagnostic features

Before making a diagnosis, the doctor takes many factors into account. These include treatments and medications, symptoms, medical history, gender, age and heredity.

When preparing for the test, the patient should remember that taking certain medications can increase or decrease the number of white blood cells in the blood. Therefore, you should definitely notify your doctor about taking them. These medications include:

Antibiotics.
Antihistamines.
Diuretics.
Corticosteroids.
Relaxers.
Clozepine.
Heparin.
Chemotherapy and radiation therapy drugs.

A lack of white blood cells is called leukopenia and can be caused by a number of diseases. These include HIV, autoimmune disorders, and bone marrow diseases. White blood cells can be reduced in severe forms of infection, diseases of the liver and spleen, and radiation therapy.

An increased number of white blood cells (leukocytosis) occurs with anemia, bone marrow tumors, and leukemia. May be due to tissue inflammation, arthritis, stress, pregnancy; allergies, asthma.

After diagnosing the cause of an increased or decreased number of white blood cells, the doctor draws up a treatment plan, during which it is necessary to take a second blood test. If the number of leukocytes does not change, this indicates a worsening of the condition, which requires correction of the treatment regimen.

Why is pathology dangerous?

Since lymphocytes are immune cells, a decrease in lymphocytes in the blood of children leads to the fact that the child’s body becomes defenseless against various infections. The child will often suffer from colds, the illnesses will be protracted, and some pathologies may become chronic. With prolonged lymphopenia, children suffer from diseases that never occur in healthy children.

The biggest danger of this condition is the high risk of cancer.

Prevention

Often, a low level of lymphocytes in the blood is due to heredity. In addition, there are no specific preventive measures that can prevent this condition.

The following measures will help reduce the risk of secondary lymphopenia:

nutritional control (daily food should contain a sufficient amount of protein and provitamin A);
timely treatment and prevention of infectious and viral diseases;
reduction of stressful situations;
normalization of the drinking regime (children need from 250 ml to 1.4 liters of fluid per day, depending on age);
regular medical examination and clinical testing of the composition of liquid connective tissue;
regular physical activity;
eliminating the lack of vitamins in the body;
regular walking and spending time in the fresh air;
complete treatment of diseases of all types;
compliance with the rules of a healthy lifestyle.

It is impossible to cure lymphopenia without the help of a doctor, so if suspicious symptoms appear, you should immediately consult a doctor. Hereditary lymphopenia can worsen the patient's quality of life, but the acquired form of this condition can be prevented by following simple rules.

Normal values

The norm of protective cells is determined by the age and gender of the person.

Lymphocytes

Normal lymphocyte levels are as follows:

children 1-24 months - 2-11 units;
children 2-10 years old - 2.6-8 units;
teenagers 11-16 years old - 1.2-5.2 units;
adult men and women - 1-4.5 units.

As the body ages, the number of lymphocytes begins to gradually decrease.

Leukocytes

Normal indicators of the number of leukocytes are the following values:

children under 12 months - 6-18 billion/l;
children 2-6 years old - 5-16 billion/l;
children 6-16 years old - 4.5-11 billion/l;
adult men - 4.2 billion/l;
adult women - 4-10.5 billion/l.

After 50 years, rates decrease, which is considered a variant of the norm.
