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 ...
The idiopathic hypereosinophilic syndrome is a disorder characterized by hypereosiophilia that is associated with eosinophil-based tissue or organ damage. While almost any organ or tissue may be damaged, the lung, skin, heart, blood vessels, sinuses, kidneys, and brain are the most commonly affected. [ 7 ]
Signs and symptoms may include weight loss, fever, malaise, cough, skin and mucosal lesions, diarrhea, and peripheral neuropathy.Cardiac symptoms are also possible. [2]In cases associated with PDGFRB and FGFR1 mutations, splenomegaly is common.
Reslizumab, a newly developed antibody directed against interleukin 5 that has been successfully used to treat 4 patients with the hypereosinophilic syndrome, may also be of use for lymphocyte-variant eosinophilia. [4] [5] [10] [11] Patients suffering minimal or no disease complications have gone untreated. [4]
Clonal hypereosinophilia, also termed primary hypereosinophilia or clonal eosinophilia, is a grouping of hematological disorders all of which are characterized by the development and growth of a pre-malignant or malignant population of eosinophils, a type of white blood cell that occupies the bone marrow, blood, and other tissues.
The age-adjusted incidence of hypereosinophilic syndrome/chronic eosinophilic leukemia reported by the International Classification of Diseases for Oncology (Version 3) is ~0.036 per 100,000 with the mean frequency of FIP1L1-PDGFRA gene fusions occurring in ~10% of patients with hypereosinophilia as detected in developed countries. The fused ...
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).
It can arise de novo or may develop in patients having the chronic form of a hypereosinophilic syndrome. Patients with acute eosinophilic leukemia have a propensity for developing bronchospasm as well as symptoms of the acute coronary syndrome and/or heart failure due to eosinophilic myocarditis and eosinophil-based endomyocardial fibrosis.
