Eosinophilia is a condition in which the number of eosinophils in the blood is abnormally high. The cellular immune system relies on white blood cells to function. Eosinophils are white blood cells that are a natural part of the cellular immune system. They help with normal physiologic processes and host defense, as well as allergy reactions and parasite infection resistance.
When there are more than 500 eosinophils per microliter, eosinophilia is stated to exist, albeit the exact cutoff differs by laboratory. Eosinophilia is divided into three categories: mild, moderate, and severe. Eosinophils account for less than 5% of a person’s circulating white blood cells.
Causes of Eosinophilia
Eosinophilia develops when the bone marrow creates too many eosinophils or when a large number of eosinophils are attracted to a specific place in the body. A number of factors can contribute to this, including:
- Allergic reactions
- Parasitic and fungal diseases
- Skin disorders
- Endocrine disorders
- Adrenal conditions
- Autoimmune disorders
It can be driven by a range of things, with parasitic infections and allergic reactions being the most common. Hypereosinophilic syndrome is a type of hypereosinophilia that causes organ damage. This syndrome has an unclear etiology or is caused by specific cancers, such as bone marrow cancer or lymph node cancer.
Other causes of eosinophilia include:
- Hay fever (allergic rhinitis)
- Eosinophilic esophagitis
- Idiopathic hypereosinophilic syndrome (HES), an extremely high eosinophil count of unknown origin
- Lymphatic filariasis (a parasitic infection)
- Hodgkin’s lymphoma (Hodgkin’s disease)
- Crohn’s disease (a type of inflammatory bowel disease)
- Ulcerative colitis (a type of inflammatory bowel disease)
- Primary immunodeficiency
- Atopic dermatitis (eczema)
- Churg-Strauss syndrome
- Eosinophilic leukemia
- Drug allergy
- Ascariasis (a roundworm infection)
- Trichinosis (a roundworm infection)
When To See The Doctor
It is usually discovered after your doctor orders blood testing to help diagnose a problem you’re already having. Although it is rarely an unexpected find, it is possible that it may be discovered by coincidence.
Discuss the implications of these findings with your doctor. Eosinophilia in the blood or tissues, as well as the results of other tests, may reveal the source of your condition. Other tests to check your condition may be suggested by your doctor.
Treatment of Eosinophilia
It’s necessary to figure out whether you have any other illnesses or diseases. The eosinophilia would most likely go away if you get a proper diagnosis and treatment for any underlying diseases or disorders.
If you have hypereosinophilic syndrome, your doctor may prescribe corticosteroids or other medications to treat you. He or she will also want to keep an eye on your health because this issue might lead to serious complications over time.
