Eosinophilic myocarditis

Kyongmin Sarah Beck, Soh Yong Jeong, Kyo Young Lee, Kiyuk Chang, Jung Im Jung
Eosinophilic myocarditis is a disease characterized by eosinophilic infiltration of the myocardium, consisting of acute necrotic stage, thrombotic stage, and fibrotic stage. Although T1 mapping has been increasingly used in various cardiac pathologies, there has been no report of T1 mapping in eosinophilic myocarditis. We report a case of 75-year-old female with eosinophilic myocarditis, whose cardiac magnetic resonance imaging included native T1 mapping, in which apical thrombi were distinctly seen as areas with decreased T1 values, next to areas of inflammation seen as increased T1 value in subendocardium...

Eosinophilic myocarditis (EM) is a rare and potentially fatal disease if left untreated. Because the disease can have a delayed presentation and can appear even after 2 years, its underlying causes often remain unknown. We report the case of a 63-year-old man with an atypical clinical presentation of hypersensitive EM and significant coronary artery disease, which was confirmed through coronary angiography. The patient was treated with hydrochlorothiazide (12.5 mg once daily for 2 years) and budesonide/formoterol (160/4...

Eosinophilic myocarditis may be accompanied by Churg-Strauss syndrome (CSS). We report a case of CSS that was accompanied by myocardial changes in the early stage. A 71-year-old woman complained of mild chest pain at rest, but routine echocardiography did not reveal any endocardial abnormalities. Four months later, the patient was hospitalized due to congestive heart failure with neuropathy of both upper extremities. A diagnosis of eosinophilic myocarditis was made based on the patient's laboratory results and the presence of mural thrombus...

Eosinophilic myocarditis (EM) is a rare form of myocarditis that usually presents with heart failure due to eosinophilic infiltration. EM is often a component of hypereosinophilic syndrome (HES). HES is a rare disorder characterized by persistent, marked eosinophilia combined with organ system dysfunction. A 38-year-old man was admitted to emergency services with left inguinal pain and fever, and was hospitalized with diagnosis of nephrolithiasis and urinary tract infection. Intravenous antibiotic therapy of 3 grams meropenem per day and analgesic of 50 mg pethidine per day were administered...

Cardiac manifestations are a major cause of morbidity and mortality in patients with eosinophil-associated diseases. Eosinophils are thought to play a pathogenic role in myocarditis. We investigated the pathways that recruit eosinophils to the heart using a model of eosinophilic myocarditis, in which experimental autoimmune myocarditis (EAM) is induced in IFNγ(-/-) IL-17A(-/-) mice. Two conditions are necessary for efficient eosinophil trafficking to the heart: high eotaxin (CCL11, CCL24) expression in the heart and expression of the eotaxin receptor CCR3 by eosinophils...

An increase in the concentration of eosinophils in blood may lead to endocarditis, myocarditis, and pericarditis. When the absolute eosinophil count increases beyond 1.5 x 10(9)/L, myocardial damage and even death can occur. This case report describes a 47-year-old male with an alcohol-induced psychotic disorder who developed eosinophilia 4 weeks after starting treatment with quetiapine 50-200 mg/d. His maximum recorded absolute eosinophil count was 7.63 x 10(9)/L (normal range < 0.5 x 10(9)/L), but the level returned to normal over a 4-week period after stopping quetiapine and no myocardial damage was observed...

An 8-year-old spayed female Munsterlander was evaluated for a chronic low grade fever and a two month history of exercise intolerance. On physical examination, tachycardia and a grade II/VI right systolic heart murmur were detected. Echocardiography revealed marked thickening of the atrial and ventricular walls with mixed echogenicity and concentric hypertrophy of the left and right ventricles and equivocal systolic dysfunction. Serum cardiac troponin I level was markedly elevated. Endomyocardial biopsy was attempted; however, the patient arrested during the procedure and resuscitation was unsuccessful...

PURPOSE OF REVIEW: The article traces the pathways leading from viral infection of the heart by coxsackievirus B3 to autoimmune myocarditis in its various manifestations. RECENT FINDINGS: Myocarditis can be induced by a number of different infectious agents and represents a significant cause of death especially in young individuals. Following infection, patients may develop lymphocytic, eosinophilic, or giant cell/granulomatous myocardial inflammation. It can lead to infectious dilated cardiomyopathy, a disease frequently requiring cardiac transplantation...

Myocarditis is a recognized but underdiagnosed cause of cardiomyopathy due to its wide clinical spectrum and nonspecific presentation. Accurate diagnosis is important because 25% of patients with acute myocarditis develop cardiomyopathy, and of those, approximately 5% per year require heart transplantation or die. Current guidelines for the recognition and treatment of the inflammatory cardiomyopathies are limited. The gold standard for diagnosis, endomyocardial biopsy, has low sensitivity, and thus, multimodality imaging of inflammation plays a crucial role in defining the cardiac abnormalities and in assisting with diagnosis and management...

Myocarditis is a clinically important disease because of the high mortality. From the perspective of treatment strategy, eosinophilic myocarditis should be distinguished from other types of myocarditis. Toxocariasis, caused by Toxocara canis or Toxocara cati, is known as a cause of eosinophilic myocarditis but is considered rare. As it is an unpopular disease, eosinophilic myocarditis due to toxocariasis may be underdiagnosed. We experienced two cases of eosinophilic myocarditis due to toxocariasis from different geographical areas in quick succession between 2013 and 2014...

BACKGROUND: Drug-induced eosinophilic myocarditis is a life-threatening and frequently overlooked condition. The prevalence of myocarditis in clozapine-treated patients may be as high as 3 %. An association between olanzapine and myocarditis has not previously been described, but given the chemical similarity between olanzapine and clozapine, we hypothesized the existence of such an association. We searched the spontaneous adverse drug reports database of the Danish Health and Medicines Authority for olanzapine and myocarditis in the period from October 21, 1996 to - June 03, 2015...

Cardiac involvement is common in primary systemic vasculitides and may be due to direct effect of the disease on the heart or due to therapy. We shall review involvement of the heart in the various forms of primary systemic vasculitis. Among anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV), eosinophilic granulomatosis with polyangiitis most commonly involves the heart. Involvement of the heart confers poorer prognosis in AAV, which is also complicated by increased risk of cardiovascular events...

Eosinophilic myocarditis (EM) represents a rare form of myocardial inflammation with very heterogeneous aetiology. In developed countries, the most prevalent causes of EM are hypersensitivity or allergic reactions, as well as hematological diseases leading to eosinophilia. The disease may have a variable clinical presentation, ranging from asymptomatic forms to life-threatening conditions. Most patients with EM have marked eosinophilia in peripheral blood. Endomyocardial biopsy needs to be performed in most cases in order to establish a definitive diagnosis of EM...

Myocarditis is an inflammatory disease of myocardium, associated with nonischemic necrosis and degeneration of myocytes. Although the clinical course is rapid, myocarditis can lead to dilated cardiomyopathy with chambers dilatation and ventricular dysfunction. The pathophysiology of myocarditis in humans is not completely understood. There are several etiological agents implicated, mainly viral agents. The clinical presentation is extremely various, with nonspecific systemic symptoms until sudden death. The great variability of symptoms makes the diagnosis, therefore, extremely difficult...

Clozapine-induced myocarditis is a poorly understood, rare, potentially fatal adverse drug reaction with absolute risks ranging from 7 to 34 per 1000 in Australia and 0.07-0.6 per 1000 in other countries. Hypersensitivity reactions have been postulated including some cases probably associated with rapid titrations. This case describes a 50-year-old African-American man with schizoaffective disorder, naïve to clozapine, who probably died from clozapine-induced myocarditis. He was started on 25 mg/day of clozapine and received 1625 mg over 14 days, prior to his death on day 15...
