The baby's lymphocytes are high and the neutrophils are low

In fact, the physical fitness of a newborn baby is very low. If you don't pay attention, it may cause various diseases. The most common ones are high lymphocytes and low neutrophils. If these two situations occur, it means that there are some problems inside the baby's body. Then you need to find out the reasons. Some drugs can be used to greatly improve the baby's condition, or even cure it.

Neutrophils and lymphocytes are the main components of white blood cells. If the proportion of one of them increases, the other will decrease. It is necessary to combine the total white blood cell count and whether the baby has fever and other symptoms to comprehensively judge this situation. If the baby has no fever and other problems, the total white blood cell count is normal, and the lymphocyte ratio is simply increased, it does not mean that there is a problem and no treatment is needed. If there is fever, viral infection may be considered

There are many causes of neutropenia. There are different classification methods. It can be divided into congenital or acquired, or it can be divided into five categories according to decreased granulocyte production, ineffective proliferation, excessive destruction, combined causes and pseudogranulocytopenia:

1. Decreased granulocyte production or maturation arrest

1. The drug acts directly on the bone marrow

Common ones include methotrexate, 6-mercaptopurine, and alkylating agents such as cyclophosphamide. Among antibiotics, chloramphenicol is the most common cause of granulocytopenia.

2. The role of radioactive substances

Radiation therapy to the spine, pelvis, sternum and other parts can affect the hematopoietic function of the bone marrow and cause granulocytopenia.

3. Hereditary neutropenia

Also known as infantile lethal neutropenia, it is a rare neutropenia that is inherited in an autosomal recessive manner.

4. Reticular dysgenesis with congenital leukocytosis

This disease is extremely rare. The disease occurs immediately after birth. The thymus, systemic lymph nodes, tonsils, and intestinal lymph nodes are all underdeveloped or stunted. The number of lymphocytes in the peripheral blood is extremely reduced, cellular immunity is low, and plasma gamma globulin is reduced. The disease is caused by defects in the development of hematopoietic stem cells. Granulocytosis is hypoplastic, with a lack of primitive granulocytes and monocytes in the bone marrow, while the erythroid and megakaryocyte systems are normal. Death often occurs in infancy from severe bacterial or viral infections.
