What disease is caused by a high percentage of eosinophils

Eosinophils are a type of white blood cell that is very fragile and can be dispersed around the cell. Many people are also concerned about the high percentage of eosinophils, which may cause some diseases, such as some allergic diseases.

(1) Allergic diseases:

In cases of bronchial asthma, drug allergy, urticaria, food allergy, angioedema, serum sickness, etc., peripheral blood eosinophilia may reach more than 10%.

(2) Parasitic diseases:

Schistosomiasis, ascariasis, hookworm disease, etc. have an increase in eosinophils in the blood, often reaching 10% or more. Patients with certain parasitic infections have a significant increase in eosinophils, with the total number of inverted white blood cells reaching tens of thousands, more than 90% of which are eosinophils, an eosinophilic leukemoid reaction.

(3) Skin diseases:

In diseases such as eczema, exfoliative dermatitis, pemphigus, and psoriasis, a mild to moderate increase in peripheral blood eosinophils may be seen.

(4) Blood diseases:

Such as chronic myeloid leukemia, eosinophilic leukemia, lymphoma, multiple myeloma, eosinophilic granuloma, etc., the peripheral blood eosinophils may increase to varying degrees, and some may be accompanied by an increase in immature eosinophils.

(5) Certain malignant tumors:

Certain epithelial tumors such as lung cancer can cause an increase in eosinophils.

(6) Certain infectious diseases:

In acute infectious diseases, eosinophils usually decrease, but scarlet fever can cause eosinophils to increase.

(7) Others:

Rheumatic diseases, hypopituitarism, allergic interstitial nephritis, etc. are often accompanied by eosinophilia.
