Eosinophilia: A Brief Discussion Regarding Causes and Management

Eosinophilia Definition

Eosinophilia is said to be present when the absolute eosinophil count is more than 400/cmm (some books mention eosinophilia when the absolute count is more than 500/cmm).

Etiology: I will describe in brief the causes of eosinophilia so that it will help in detecting the underlying cause of eosinophilia.

1. Allergic disorders: This is the first cause that has to be ruled out.

2. Parasitic infestations: Following parasites can lead to high eosinophils.

3. Skin disease:

4. Pulmonary eosinophilia

5. Miscellaneous:

Eosinophilia Diagnosis

  1. Chest X-ray and spirometry for asthma.
  2. Liver and kidney profile test.
  3. Stool analysis and serological test for parasitic infestation.
  4. Allergy testing to find causative allergen.
  5. Peripheral smear examinations and bone marrow study to rule out a myeloproliferative neoplasm.
  6. Elisa test for HIV (human immunodeficiency virus).

So, according to need various tests are done.

Eosinophilia Treatment

- In allergy disorder, Corticosteroid or Montelukast or strong anti-inflammatory drug can be prescribed.

- In asthma, bronchodilator inhaler or nebulization also can be prescribed as per need.

- For parasites, Albendazole 400 mg is a good drug.

- For skin problem, according to the cause, treatment is done like for example, topical Betamethasone.

Footnote: Do not neglect high eosinophils in CBC. Rule out the underlying cause and accordingly, treatment is done. Hope this article is useful to you.
