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 .
Eosinopenia is defined as an absolute eosinophil count of less than 0.09 × 10 9 /L and can be difficult to detect because the reference interval is low. Eosinopenia often accompanies other cytopenias in conditions that result in marrow hypoplasia, specifically involving leukocytes.
A low number of eosinophils in the blood (eosinopenia) can occur with Cushing syndrome, bloodstream infections (sepsis), and treatment with corticosteroids. However, a low number of eosinophils does not usually cause problems because other parts of the immune system compensate adequately.
Eosinopenia is defined as a reduction of circulating eosinophils <0.01 × 10 9 /l. Idiopathic eosinopenia appears to be a very rare event or syndrome. Eosinopenia in acute stress is mediated by adrenal glucocorticosteroids and epinephrine, while in acute inflammatory states it is not dependent upon the endocrine mechanisms.
Eosinopenia is the result of having a less than normal amount of eosinophils in your body. Types of eosinopenia include: Cushing’s syndrome: This condition occurs when there is too much cortisol in your body and not enough eosinophil cells. Cortisol is a hormone that regulates your blood sugar and turns food into energy.
25 lip 2019 · Eosinophilic disorders represent a group of pathologic conditions with highly heterogeneous pathophysiology and clinical presentation and variable prognosis, ranging from asymptomatic or mild, to severe and complex cases, with fatal outcome.
28 sty 2018 · Eosinophils are thought to provide a stereotyped response towards necrosis (a hallmark of cancer biology) either favouring an antitumour inflammatory response or a protumour misrepair response with enhanced angiogenesis and release of growth factors, depending on the surrounding stimuli [57, 189, 190].
