Eosinophil chemotactic factor of anaphylaxis (ECF-A)
A substrate released from mast cells during anaphylaxis which attracts eosinophils.
Eosinophilia
An abnormally high number of eosinophils in the blood. Normally, eosinophils constitute 1 to 3% of the peripheral blood leukocytes, at a count of 350 to 650 per cubic millimeter. Eosinophilia can be categorized as mild (less than 1500 eosinophils per cubic millimeter), moderate (1500 to 5000 per cubic millimeter), or severe (more than 5000 per cubic millimeter).
Eosinophilia-myalgia syndrome
Resembles eosinophilic fasciitis - due to L-Tryptophan.
Eosinophilic fasciitis
A scleroderma-like condition in which there is skin thickening and tethering with oedema along with thickening of the sub-epidermal fascia and infiltration with eosinophils. (Shulman's syndrome)
Eosinophilic gastroenteritis
Infection and swelling of the lining of the stomach, small intestine, or large intestine. The infection is caused by white blood cells (eosinophils).
Eosinophilic meningitis
Meningitis with a high percentage of eosinophils (a type of white blood cell) in the cerebrospinal fluid (CSF). The usual cause is the parasite Angiostrongylus cantonensis, also known as the rat lungworm. People become infected with this parasite by ingesting its larvae in raw or insufficiently cooked snails, slugs, freshwater prawns, frogs, or fish. Infection may also occur by consumption of fresh produce such as contaminated lettuce. When the larvae are ingested, they penetrate the intestinal tract, go into blood vessels, and eventually reach the meninges (the covering of the brain and spinal cord). The larvae usually die there shortly thereafter. An eosinophilic reaction develops in response to the dying larvae. It is manifested by an outpouring of eosinophils in the CSF.
