OBJECTIVE: To compare echocardiograms and endomyocardial biopsies to diagnose cardiac involvement in hypereosinophilic syndrome. METHODS: We examined the agreement between echocardiography and endomyocardial biopsies to detect cardiac involvement in hypereosinophilic syndrome by reviewing cases identified as hypereosinophilia or hypereosinophilic syndrome in Mayo Clinic databases from January 1978 through June 2009. Single-organ cases of eosinophilia such as eosinophilic fasciitis and eosinophilic gastroenteritis were excluded...

An 11-year-old male castrated domestic shorthair cat presented with left central vestibular dysfunction. Magnetic resonance imaging of the brain revealed a large, extra-parenchymal, strongly contrast-enhancing mass at the level of the left cerebellopontine angle and compressing the cerebellum and brainstem. The mass was surgically excised via left rostral and sub-tentorial craniectomies and histopathology revealed an epithelial neoplasm composed of anastomosing cords of neoplastic cells that contained large amounts of finely granular hypereosinophilic cytoplasm and round nuclei...

Idiopathic hypereosinophilic syndrome is a condition of unknown etiology characterized by proliferation of eosinophils and their infiltration into tissues. Although cardiac involvement is rare, eosinophilic myocarditis can lead to life-threating fulminant congestive heart failure. Treatment of patients with eosinophilic myocarditis is challenging as heart failure can be caused by biventricular dysfunction. To our knowledge, this is the first case reported in the literature describing a patient with acute severe biventricular heart failure caused by eosinophilic myocarditis with mural left ventricular apical thrombus who was successfully treated with implantation of a total artificial heart as a bridge to heart transplant...

Hypereosinophilic syndrome is a rare entity that can develop secondary to overproduction of eosinophilopoietic cytokines or as idiopathic disease. Cardiac involvement, which occurs often, is divided into 3 stages, the latter of which is nonreversible and leads to severe heart failure. Early detection and treatment of the syndrome is essential. For this reason, genetic testing for the FIP1L1-PDGFRA fusion gene has recently been added to the diagnostic algorithm. Patients with this mutation are at increased risk for the development of cardiac involvement and typically respond to treatment with the tyrosine kinase inhibitor imatinib mesylate...

Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome, is a rare systemic disease situated between primary small vessel vasculitides associated with antineutrophil cytoplasmic antibodies (ANCAs) and hypereosinophilic syndromes (HES). Here, we present a case of EGPA in a 38-year-old male, with a previous diagnosis of asthma, who presented with fever, migratory lung infiltrates and systemic eosinophilia that was refractory to previous courses of antibiotics. This case highlights the importance of the primary care physician understanding the differential diagnosis of pulmonary eosinophilic syndromes...

Asthma is a highly prevalent chronic disease of the airways; approximately 10% of patients with asthma will experience a severe form of the disease. New understanding of the pathogenesis of asthma has enabled the development of novel drugs and provided hope for patients with asthma. Interleukin (IL)-5 and IL-5 receptor subunit α (IL-5-Rα) plays a crucial role in the development, maturation, and operation of eosinophils so were the first important therapeutic target of these new drugs. While the results of early clinical trials of these drugs were not promising, results improved once researchers discovered the drugs worked best in patients with high eosinophil levels...

Inflammatory dilated cardiomyopathy (DCMi) is a major cause of heart failure in children and young adults. DCMi develops in up to 30% of myocarditis patients, but the mechanisms involved in disease progression are poorly understood. Patients with eosinophilia frequently develop cardiomyopathies. In this study, we used the experimental autoimmune myocarditis (EAM) model to determine the role of eosinophils in myocarditis and DCMi. Eosinophils were dispensable for myocarditis induction but were required for progression to DCMi...

Hypereosinophilic syndrome (HES) is a rare hematological disorder, which may present with cardiac involvement. The case is presented of a 61-year-old male patient with isolated aortic stenosis secondary to non-bacterial thrombotic endocarditis and HES. The patient underwent successful aortic valve replacement with a bioprosthesis and remained recurrence-free at the 18-month follow up. A review of the current literature is also presented and cardiac manifestations, clinical presentation and surgical issues in the care of patients with this rare condition are discussed...

Endomyocardial fibrosis (EMF) is the most common cardiac abnormality in hyeperosinophilic syndrome (HES), sometimes complicated with mitral valve disease. Mitral valve disease without ventricular manifestation is very rare, however. Case reports link HES to prosthetic valve thrombosis (PVT), but the optimal type of prosthetic valve in HES is not known. Herein is reported the case of a young female HES patient with secondary mitral valve degeneration and severe regurgitation. A mechanical prosthetic valve was implanted six months after she was diagnosed with HES, but despite anticoagulation and antiplatelet therapy she developed PVT three months later...

BACKGROUND: Endocarditis parietalis fibroplastica Löfflein (EPF) is a rare form of primary restrictive cardiomyopathy with poor prognosis. It is generally caused by hypereosinophilic syndrome with eosinophilic penetration of the heart. This leads to congestive heart failure in three different stages. As a frequent manifestation of neoplastic diseases, cardiac involvement means poor prognosis. CASE PRESENTATION: The present report deals with a case of EPF caused by non-specified T-cell lymphoma (T-NOS)...

Persistently elevated eosinophil granulocytes in the peripheral blood in children is challenging because of a complex diagnosis especially after solid organ transplantation and can lead to difficulties in finding an underlying causative factor.We report a 12-year-old boy who developed severe hypereosinophilia 11 years after liver transplantation due to biliary atresia. Accompanying symptoms were recurrent fever, fatigue, elevated liver enzymes, abdominal pain, and significant weight loss. After exclusion of secondary causes of eosinophilia, an idiopathic hypereosinophilic syndrome (I-HES) was diagnosed...

A 43-year-old female patient with mitral valve stenosis and hypereosinophilia on admission received mechanical mitral valve replacement. During the 2 years after the first surgery, the patient underwent two mitral valve revision operations for repeated prosthetic mitral valve thrombosis. During the 2-year period, the patient's absolute eosinophil count was found elevated repeatedly. Finally, fluke antibody detection revealed fluke infection and, after praziquantel treatment, a normal level of absolute eosinophil count has been maintained and recurrent thrombosis has not occurred for 18 months...

Dexpramipexole, an orally bioavailable small molecule previously under clinical development in amyotrophic lateral sclerosis, was observed during routine safety hematology monitoring to demonstrate pronounced, dose- and time-dependent eosinophil-lowering effects, with minor reductions on other leukocyte counts. Analysis of hematology lab values across two double-blind, randomized placebo-controlled clinical trials at total daily doses ranging from 50mg to 300mg demonstrated that dexpramipexole consistently and markedly lowered peripheral blood eosinophils...

Hypereosinophilic syndrome (HES) is a group of rare blood disorders characterized by a persistent elevation of blood eosinophil count ⩾1.5×10(9)/L and clinical manifestations attributable to eosinophilia or tissue hypereosinophilia. Lymphocytic variant of HES (HES-L) is a known subtype according to World Health Organization classification. It is well documented in the literature that patients with HES-L are predisposed to develop T-cell lymphoma. We report a case of T-cell lymphoproliferation associated with hypereosinophilia, which has been successfully treated with mycophenolate mofetil, with resolution of skin lesions and normalization of eosinophil count and immunoglobulin E level...

We present the case of a 48-year-old female with acute onset altered mental status, who was found to have eosinophilia, elevated troponin, and embolic strokes. Extensive testing for autoimmune, infectious, and coronary artery etiologies was unremarkable. After a cardiac MRI revealed focal myocardial hyperenhancement, the patient underwent an endomyocardial biopsy with findings consistent with eosinophilic myocarditis. The patient was diagnosed of idiopathic hypereosinophilic syndrome and started on prednisone and apixaban...

A total of 3 cases of pseudoherpetic transient acantholytic dermatosis (Grover disease) are presented, followed by a brief review of prior reports. All 3 patients were above the age of 60 and presented with a pruritic eruption composed of papules with or without vesicles distributed on the trunk. For all 3 patients, the clinical differential diagnosis included drug eruption but did not include Grover disease; in 1 patient, the clinical impression included herpesvirus infection. Similar histologic and immunohistochemical findings were demonstrated in all 3 cases...

Mice with mutations in SHANK-associated RH domain interactor (Sharpin) develop a hypereosinophilic auto-inflammatory disease known as chronic proliferative dermatitis. Affected mice have increased apoptosis in the keratinocytes of the skin, esophagus, and forestomach driven by extrinsic TNF receptor mediated apoptotic signaling pathways. FAS receptor signaling is an extrinsic apoptotic signaling mechanism frequently involved in inflammatory skin diseases. Compound mutations in Sharpin and Fas or Fasl were created to determine if these death domain proteins influenced the cutaneous phenotype in Sharpin null mice...

Some cutaneous inflammatory disorders are typified by a predominant or exclusive localization in the dermis. They can be further subdivided by the principal cell types into lymphocytic, neutrophilic, and eosinophilic infiltrates, and mixtures of them are also seen in a proportion of cases. This review considers such conditions. Included among the lymphoid lesions are viral exanthems, pigmented purpuras, gyrate erythemas, polymorphous light eruption, lupus tumidus, and cutaneous lymphoid hyperplasia. Neutrophilic infiltrates are represented by infections, Sweet syndrome, pyoderma gangrenosum, and hidradenitis suppurativa, as well as a group of so-called "autoinflammatory" dermatitides comprising polymorphonuclear leukocytes...
