Eosinophilia is a condition in which the eosinophil count in the peripheral blood exceeds 5 × 10 8 /L (500/μL). [1] Hypereosinophilia is an elevation in an individual's circulating blood eosinophil count above 1.5 × 10 9 /L (i.e. 1,500/μL).
Eosinopenia is a condition where the number of eosinophils, a type of white blood cell, in circulating blood is lower than normal. [1] Eosinophils are a type of granulocyte and consequently from the same cellular lineage as neutrophils, basophils, and mast cells.
Eosinophils are also involved in many other biological processes, including postpubertal mammary gland development, oestrus cycling, allograft rejection and neoplasia. [21] They have also been implicated in antigen presentation to T cells. [22] Eosinophils are responsible for tissue damage and inflammation in many diseases, including asthma.
The diagnosis of familial eosinophilia rest upon a) familial clustering of the disorder; b) exclusion of "family acquired eosinophilia" (i.e. eosinophilia due to chronic parasite or other infestations that afflict multiple members of a family); c) lack of eosinophil-induced tissue destruction such as that which occurs in the hypereosinophilic ...
Depending on eosinophil target-organ infiltration, the clinical presentation of hypereosinophilic syndrome (HES) varies from patient to patient. [13] Individuals with myeloproliferative variant HES may be more likely to experience mucosal ulcerations involving the genitalia or airways, while patients with lymphocytic variant HES typically exhibit prominent skin symptoms such as urticarial ...
When the doctors finally took an echocardiograph of the child they discovered that the "patient's admission blood count showed leukocytosis with an abnormally elevated level of peripheral eosinophils." [11] The child was then diagnosed with Löffler's endocarditis, and immediately began immunosuppressive therapy to decline the eosinophilic count.
Eosinophils and other immune cells are found in the upper layer of the skin in erythema toxicum neonatorum lesions. [5] [9] Immune cells tend to cluster around hair follicles in particular. The leading hypothesis about the cause of erythema toxicum neonatorum is that bacteria activate the immune system when they enter hair follicles for the ...
Acute eosinophilic pneumonia can occur at any age, even in previously healthy children, though most patients are between 20 and 40 years of age. Men are affected approximately twice as frequently as women. Acute eosinophilic pneumonia has been associated with smoking. Chronic eosinophilic pneumonia occurs more frequently in women than men and ...
