Increased lymphocytes in the blood of the child

During childbirth, the child moves from a sterile environment, which is the mother's womb, to a non-sterile environment-the surrounding world.

During this period, the child is protected from the hostile factors of the new world surrounding him only with antibodies transmitted to him by the mother's body.
His own body is not yet capable of producing protective antibodies. Gradually, the immune system is becoming. And only by the age of 6 you can talk about ripened immunity. Lymphocytes are the main strength of good immunity. They specialize in the destruction of viral infections. Lymphocytes are divided into:

- B-lymphocytes are scouts, they are looking for alien, hostile microorganisms;

- T-lymphocytes are controllers, they control the immune reaction of the body, if it is necessary to strengthen this reaction, then the T-hellers enter into the matter, and if necessary suppress T-suppressors are activated;

- NK-lymphocytes are "natural killers" - they destroy foreign cells.

Lymphocytes in the blood of an adult person are normally 20-35%.

At children this indicator is not constant and varies depending on age:

- From birth to 4 days - 20-22%;

- 4-7 days - 40-45%;

- 8 days - 6 years - 45-67%, with the greatest increase in lymphocytes in the blood of the child in 12-24 months;

- with 6 years, these figures begin to decline and by 15 years have stabilized in the range of 20-35%.

Elevated lymphocytes in the blood of the child or lowered, the hemogram will show.

Lymphocytosis

Pathological increase in the level of lymphocytes - lymphocytosis - is divided into relative and absolute.

Relative lymphocytosis is an increase in the percentage of lymphocytes in the leukocyte formula while maintaining their normal number.

With absolute lymphocytosis, the total number of lymphocytes in the blood increases.

If it is revealed that the lymphocytes in the blood are increased in the child by a relative type, this indicates the transferred infectious diseases. The child's organism tolerates illness more heavily, the immune system reacts very violently, so the tests immediately show an elevated level of lymphocytes. But the recovery in infants takes less time than in adults. In addition, if the lymphocytes are increased, the reasons can be as follows:

- typhoid fever;

- Some types of avitaminosis;

- Endocrine pathologies;

- starvation;

- the period after preventive vaccinations.

A blood test showing that the lymphocytes in the blood of an absolute type child is elevated should be the basis for a serious examination, as this may be a symptom of such formidable diseases as tuberculosis, rubella, acute viral hepatitis, chicken pox, cytomegalovirus infection, lymphocytic angina, Hyperthyroidism, leukemia by type of lymphoblastic leukemia, lymphosarcoma. In these cases, the level of lymphocytes can reach 90-95%.

Lymphocytopenia

Lowering the level of lymphocytes below the norm is called lymphocytopenia. Lymphocytopenia is also relative and absolute. Relative lymphocytopenia is accompanied by inflammatory-purulent processes, pneumonia. Absolute lymphocytopenia is observed in pathologies of red bone marrow, with the death of a large number of lymphocytes, for example, with HIV.

It is very important to start treatment in time, because the consequences can be daunting. Protecting the body (especially children's) is the foundation of health, and you are responsible for ensuring that the number of lymphocytes is always normal.
