Eosinopenia is associated with several disease states and conditions, including inflammation and sepsis, endogenous catecholamines, and use of glucocorticoids. [1] There are also medications that deliberately target eosinophils in order to treat eosinophil-mediated diseases, causing drug-induced eosinopenia.
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.
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.
Most recently, treatment with eosinophil-targeted therapies in a subset of eosinophilic asthma patients using anti-IL5 or anti-IL5R results in increased lung function and decrease diseases flares, and now both types of biologics have been approved for use as add-on to maintenance therapies in severe asthma with eosinophilic phenotype (moderate ...
Independent of the underlying disease, patients with overt or imminent organ damage (HES) are candidates for early therapeutic intervention. In those with secondary HES, treatment of the underlying disease is usually effective. In some patients with HES, IL-5-targeting antibodies may work.
Disease Overview: The eosinophilias encompass a broad range of nonhematologic (secondary or reactive) and hematologic (primary or clonal) disorders with potential for end-organ damage. Diagnosis: Hypereosinophilia (HE) has generally been defined as a peripheral blood eosinophil count greater than 1.5 109/L.
