Familial eosinophilia is a rare congenital disorder characterized by the presence of sustained elevations in blood eosinophil levels that reach ranges diagnostic of eosinophilia (i.e. 500–1500/microliter) or, far more commonly, hypereosinophilia (i.e. >1,500/microliter).
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 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 ...
More than 1,500/mL of blood eosinophilia for more than six months in a row, along with hypereosinophilic disease signs and symptoms. [23] Lack of an underlying cause for hypereosinophilia after a full diagnostic assessment. [23] Organ dysfunction or damage as a result of eosinophils' toxic contents being released locally. [23]
Peripheral blood eosinophilia and elevated serum IgE are usual but not universal. The damage to the gastrointestinal tract wall is caused by eosinophilic infiltration and degranulation. [15] As a part of host defense mechanism, eosinophils are normally present in gastrointestinal mucosa, though the finding in deeper tissue is almost always ...
It is associated with complications in the mid-trimester of a pregnancy leading to premature births. [2] Although most prevalent in individuals of Scandinavian origin, there have also been scattered cases in people of Japanese, Italian and Indian ethnicity. [1] [3] [4] This disorder is also referred to as ichthyosis congenital type IV. [1]
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.
