Eosinophilic myocarditis is often viewed as a disorder that has three progressive stages. The first stage of eosinophilic myocarditis involves acute inflammation and cardiac cell necrosis (i.e. areas of dead cells); it is dominated by symptoms characterized as the acute coronary syndrome such as angina, heart attack and/or congestive heart failure.
Eosinophilic myocarditis is a subtype of myocarditis in which cardiac tissue is infiltrated by another type of pro-inflammatory blood cell, the eosinophil. Eosinophilic myocarditis is further distinguished from non-eosinophilic myocarditis by having a different set of causes and recommended treatments. [36] [20]
Additionally, and unlike in other forms of myocarditis, eosinophilic myocarditis may also show enhanced gadolinium uptake in the sub-endocardium. [8] [10] However, the only definitive test for Loeffler endocarditis is cardiac muscle biopsy showing the presence of eosinophilic infiltrates. Since the disorder may be patchy, multiple tissue ...
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).
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. [1] [2] Hepatomegaly and splenomegaly are more common than in other variants of AML.
The symptoms of DRESS syndrome usually begin 2 to 6 weeks but uncommonly up to 8–16 weeks after exposure to an offending drug. Symptoms generally include fever, an often itchy rash which may be morbilliform or consist mainly of macules or plaques, facial edema (i.e. swelling, which is a hallmark of the disease), enlarged and sometimes painful lymph nodes, and other symptoms due to ...
