Elevated eosinophils: causes

Eosinophils – a subspecies of white blood cells (leukocytes), which help our body to fight diseases and infections by “eating” certain types of bacteria, foreign substances, parasites and other “enemies” of the body. But if they are so useful, why is elevated eosinophils are seen by doctors as something wrong? Let's try to answer this question.

Elevated eosinophils: common causes

Increased eosinophils in the blood (this condition is called eosinophilia) Can be a response of the organism to allergies. Their number may increase at a time when the body there are any bacteria or parasites. Eosinophils in the blood may rise, if a person has some types of disorders of the skin, as, for example, pemphigus, which on the body blisters.

Increased eosinophils can also be the consequence of diseases that lead to an increase in myeloid tissue located in the bone marrow. One such disease is polycythemia Vera-her in the blood increases the number of red corpuscles and other blood cells. Another disease is myelofibrosis, in which the myeloid tissue in bone marrow is replaced by fibrous.

Some types of medications increase the level of the leukocyte. These can be penicillin, aspirin, diphenhydramine, imipramine, beta-blockers and many other drugs.

Elevated eosinophils: rare diseases

A Number of collagen vascular diseases may lead to an increase in eosinophils. This is a group of acquired diseases, all of which are striking blood vessels and connective tissue. Also revealed elevated eosinophils, if a person is detected eosinophilic gastroenteritis – a very rare disease. When the eosinophils are released into the small intestine and are in stool.

There is another swamping – sarcoidosis. Eosinophils above the norm can also be the consequence of the disease. Sarcoidosis-is a condition where in the respiratory tract tissues forming little bumps. 

The Syndrome Leffler also leads to an increase of eosinophils. The disease manifests itself in the form of cough and fever such further deterioration, such as respiratory failure.

Addison's Disease also leads to an increase in the number of eosinophils. This is a disease whereby the adrenal glands do not produce hormones at all or produce too little.

This list is not full. Increased eosinophils have also been observed in atopic (e.g., asthma), parasitic (fascioliasis, hookworm, etc.), Autopista skin (e.g. epidermolysis bullosa), gastrointestinal (liver cirrhosis), rheumatic (rheumatoid arthritis, etc.), hematological (acute leukemia, pernicious anemia, etc.) diseases. Disease mixed group: hypoxia, splenectomy, chorea and others.

Therefore, the analysis to determine the level of eosinophils is so important for doctors. It helps to identify one of the above and many other diseases and conditions of the body.
