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] In 10% to 25% of patients, mostly ...
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 ...
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).

White blood cell levels either rise in distinct white blood levels or in unison with others, a patient may have neutrophilia, lymphocytosis, monocytosis, eosinophilia, basophilia or a rise in immature blast cells. [2] Acute myeloid leukemia - 10 to 20 percent of patients newly diagnosed with this type leukemia have hyperleukocytosis.
Laboratory tests commonly reveal the presence of immune-mediated hemolytic anemia; elevated blood levels of eosinophils, gamma globulins, and lactic dehydrogenase; high erythrocyte sedimentation rates; and positive blood tests for autoantibodies such as rheumatoid factor, anti-nuclear antibody, and anti-smooth muscle antibody.
Leukocytosis can be subcategorized by the type of white blood cell that is increased in number. Leukocytosis in which neutrophils are elevated is neutrophilia; leukocytosis in which lymphocyte count is elevated is lymphocytosis; leukocytosis in which monocyte count is elevated is monocytosis; and leukocytosis in which eosinophil count is elevated is eosinophilia.
In adults, absolute lymphocytosis is present when the lymphocyte count is greater than 5000 per microliter (5.0 x 10 9 /L), in older children greater than 7000 per microliter and in infants greater than 9000 per microliter. [1] Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds ...
