  2. Eosinophilia - Wikipedia

    en.wikipedia.org/wiki/Eosinophilia

    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 ).

    For instance, patients with eosinophilic asthma have high levels of eosinophils that lead to inflammation and tissue damage, making it more difficult for patients to breathe. [6] [7] Eosinophils persist in the circulation for 8–12 hours, and can survive in tissue for an additional 8–12 days in the absence of stimulation. [8]

  4. Familial eosinophilia - Wikipedia

    en.wikipedia.org/wiki/Familial_eosinophilia

    Studies on other disorders associated with high levels of blood eosinophils (e.g. childhood asthma, schistosomiasis) have likewise linked eosinophilia to the q31-q33 area of chromosome 5. The 5q31-q33 region contains a cytokine gene cluster that includes genes for Interleukin 3 , interleukin 5 , and granulocyte-macrophage colony-stimulating ...

    In 1987, however, a 42-year-old male patient was described who presented with cardiac failure, mitral heart valve regurgitation, pericardial effusion, splenomegaly, kidney dysfunction, non-specific skin lesions, a six-year history of eosinophilia, and, on admission, an eosinophil blood count of 7,150 per microliter (normal <500/microliter), a ...

  6. Hypereosinophilic syndrome - Wikipedia

    en.wikipedia.org/wiki/Hypereosinophilic_syndrome

    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 ...

  7. Eosinophilic pneumonia - Wikipedia

    en.wikipedia.org/wiki/Eosinophilic_pneumonia

    Eosinophils play a central role in defending the body against infection by parasites. Many diseases, such as asthma and eczema, are caused when eosinophils overreact to environmental triggers and release an excess of chemicals, e.g., cytokines and histamine. The common characteristic among different causes of eosinophilic pneumonia is ...

  8. Clonal hypereosinophilia - Wikipedia

    en.wikipedia.org/wiki/Clonal_hypereosinophilia

    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.

  9. Eosinophilic gastroenteritis - Wikipedia

    en.wikipedia.org/wiki/Eosinophilic_gastroenteritis

    Eosinophilic gastroenteritis (EG or EGE), also known as eosinophilic enteritis, [1] is a rare and heterogeneous condition characterized by patchy or diffuse eosinophilic infiltration of gastrointestinal (GI) tissue, first described by Kaijser in 1937.
