What is Eosinophilia – Troubleinthepeace

There are many causes of eosinophilia. Blood tests can measure eosinophil levels. Peripheral eosinophilia can be divided into three categories: primary, secondary, and idiopathic.

You are viewing: What is Eosinophilia?

Eosinophilia (eosinophil) is an abnormal increase in the number of eosinophils in the blood, tissues or organs.

This condition can also be due to disordered eosinophil formation, or to an abnormal accumulation or deficiency of a certain type of white blood cell.

An increase in this white blood cell type is often associated with an immunoregulatory response, which occurs in many pathological processes, including inflammatory responses, allergies, cancer, and parasitic infections.

Eosinophilia is a manifestation of a hematological problem that needs to be investigated and diagnosed. Some of the following causes can increase eosinophils:

Due to allergies: allergic rhinitis, atopic allergies, bronchial asthma. Due to skin disorders: Pemphigus disease, nodular forms such as Pemphigus, arteritis nodosa (Polyarteritis Nodosa).
Blood tests

Due to bacterial infection: scarlet fever (Scarlet Fever), leprosy (Leprosy).Due to using drugs or radiation therapy: radiation therapy, Aspirin, Chlorpropamide, Erythromycin, Imipramine, Methotrexate, Nitrofurantoin, Procarbazine, Sulfonamides.Do myeloproliferative disorders and other malignancies: chronic myelogenous leukemia (CML), Hodgkin lymphoma, Non-Hodgkin lymphoma, polycythemia vera, myelofibrosis (Myelofibrosis). other: gastroenteritis eosinophilia (EG – Eosinophilic Gastroenteritis), Sarcoidosis, Addison’s disease, Loeffler’s syndrome.

Eosinophilia Peripheral hyperplasia can be divided into three categories: primary, secondary, and idiopathic.

Primary increase: common in blood malignancies such as chronic myeloproliferative disorders, acute leukemia. Secondary increase: often due to parasitic infections, allergic conditions, autoimmune conditions, poisoning , medications, endocrine disorders. Spontaneous hyperplasia: diagnosed when primary and secondary hyperplasia are excluded.

3.2 Classification of eosinophilia with pathologies


Eosinophilia associated with allergic diseases.Eosinophils with pulmonary infiltrates.HIV infection and immunodeficiency.Eosinophils due to parasitic infections: mainly multicellular parasites. The degree of elevation more or less reflects the tissue invasion of the parasite.Eosinophils are associated with skin diseases.Eosinophils are associated with multiple organ damage. Mast cell neoplasms.Sydrome idiopathic eosinophilia.Acute eosinophilic leukemia.U Lympho.occlusive arterial diseaseImmune deficiency.

The normal number of eosinophils is between 50 and 500 cells/microliter of blood and has a prevalence of about 2 to 11%.Eosinophilia in the blood is when the eosinophil count is more than 450 cells/microliter of blood. However, some studies use a threshold of 350-500 cells and consider this to be a normal level. An increase in the percentage of eosinophils but no increase in the absolute number (due to a decrease in other white blood cell lines) can cause diagnostic confusion. Eosinophil counts vary throughout the day, often being high in the early morning and low in the afternoon. Eosinophils are also higher in infants in the perinatal period and decrease gradually with The baby grows. During pregnancy, the eosinophils decrease, but during labor, it almost disappears from the peripheral blood. Using some drugs or preparations can affect and change the eosinophil index in the blood. blood.
