Based on their causes, hypereosinophilias can be sorted into subtypes. However, cases of eosinophilia, which exhibit eosinophil counts between 500 and 1,500/μL, may fit the clinical criteria for, and thus be regarded as falling into, one of these hypereosinophilia categories: the cutoff of 1,500/μL between hypereosinophilia and eosinophilia is somewhat arbitrary.
Eosinophilic pneumonia is a disease in which an eosinophil, a type of white blood cell, accumulates in the lungs. These cells cause disruption of the normal air spaces where oxygen is extracted from the atmosphere. Several different kinds of eosinophilic pneumonia exist and can occur in any age group.
There are many causes of eosinophilia that may underlie eosinophilic myocarditis. These causes are classified as primary (i.e. a defect intrinsic to the eosinophil cell line), secondary (induced by an underlying disorder that stimulates the proliferation and activation of eosinophils), or idiopathic (i.e. unknown cause).
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.
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 ...
Criteria for the diagnosis include findings of: a) long term hypereosinophilia (i.e. eosinophil blood counts >1,500/microliter) plus physical findings and symptoms associated with the disease; b) bone marrow analysis showing abnormally high levels of eosinophils; c) elevated serum levels of Immunoglobulin E, other immunoglobulins, and CCL17; d ...
Inflammatory arthritis can sometimes cause symptoms in parts of the body other than the joints, like the eyes, heart, or lungs. As arthritis progresses, joint damage can get worse.
The most common symptom of eosinophilic bronchitis is a chronic dry cough lasting more than 6–8 weeks. [3] Eosinophilic bronchitis is also defined by the increased number of eosinophils, a type of white blood cell, in the sputum compared to that of healthy people. [2]
