Eosinophils — specific white blood cells that perform several important functions. In particular, they provide a strong immunity as they have cytotoxic properties. But what does it mean if the eosinophils are elevated in an adult?

eosinophils in the blood increasedBrief description and functions

Eosinophils — of segmented granulocytes with guadalcacin core. For these cells characteristically amoeboid movement, they are quite easily penetrate through the walls of blood vessels. Another important property of these structures is the chemotaxis-the ability of active movement in the direction of inflammation or areas of tissue damage. By the way, these cells are microphages and can absorb the foreign particles of small size.

Eosinophils can actively linked, or, conversely, to release histamine and other substances released during inflammation or allergic reactions. There are many reasons due to which the eosinophils are elevated. The adult norm of these cells ranges from 120 to 350 per microliter of blood. Any deviation may signal the presence of problems.

Eosinophils increased: reasons

eosinophils increased in adultIndeed, such disruption of normal blood usually indicates a different malfunction of the body. Therefore, if eosinophils increased (adult or child - does not matter) is the occasion for a full examination. Today it is accepted to allocate some the main causes of eosinophilia. Here are those that occur most often:

  • In the first place is to mention the allergies. Indeed, as already mentioned, the eosinophils readily bind or release histamine, increase in level which in turn leads to the appearance of major symptoms such as skin rash or swelling of the mucous membranes. By the way, this kind of white blood cell has the ability to suspend and to start the mechanism of development of allergic reactions. These include bronchial asthma, allergic rhinitis and hay fever, atopic dermatitis, increased sensitivity to some components of medicines.
  • If the eosinophils in the blood is increased, it may indicate the presence of parasitic diseases, as one of the functions of the data cell is providing antiparasitic immunity. It is not surprising that eosinophilia develops on the background of ascariasis, malaria, trichinosis, opisthorchiasis, giardiasis, etc.
  • The Processes of formation and growth of the tumor often lead to an increase in the number of cells. These include leukemia, eritremii and some other diseases.
  • On the background of infectious diseases is also often observed eosinophilia.
  • Problems of the immune system often affect the blood count, because granulocytes are a very important part of protecting the body.
  • To the same result are some heart defects, lesions of connective tissue, for example, rheumatoid arthritis.
  • On the level of blood eosinophils may affect some medications, particularly those that contain beta-blockers, penicillin, sex hormone, chymotrypsin, sulfonamides, and other substances.causes of increased eosinophils

As you can see, eosinophils are elevated in an adult for different reasons, so an accurate diagnosis is necessary to collect anamnesis, to see the symptoms and complaints of the patient, and also conduct a number of additional analyses and research.
