Certain infections are known to cause an increase in eosinophils, a type of white blood cell. Ascariasis is one such infection.
Eosinophilia, the condition of having a high eosinophil count, can be triggered by a variety of factors, including infections, allergies, and certain medical conditions. Below is a more comprehensive list including infections and other causes linked to increased eosinophils:
Causes of Eosinophilia
While infections are a key cause, eosinophilia can stem from various sources.
Infections
- Ascariasis (a roundworm infection): Parasitic infections, like those caused by roundworms, often lead to an increase in eosinophils as the body tries to fight off the parasite.
Allergic Reactions
- Allergies: Allergic reactions, whether to food, medications, or environmental allergens, can trigger eosinophil production.
- Asthma: This chronic respiratory disease is associated with inflammation and increased eosinophils in the airways.
- Atopic dermatitis (eczema): This skin condition is characterized by inflammation and can be associated with elevated eosinophil levels.
Other Medical Conditions
- Acute myelogenous leukemia (AML): A cancer of the blood and bone marrow, can sometimes be associated with eosinophilia.
- Cancer: Certain types of cancer can stimulate eosinophil production.
- Churg-Strauss syndrome: This rare disorder causes inflammation of blood vessels and is often associated with increased eosinophils.
- Crohn's disease: This inflammatory bowel disease can sometimes lead to eosinophilia.
In summary, while ascariasis (roundworm infection) is specifically mentioned as an infection causing eosinophils, many other conditions, including other infections, allergies, and certain diseases, can also lead to increased eosinophil counts.
