Viral myocarditis is an inflammation of the heart muscle triggered by direct virus-induced cytolysis and immune response mechanisms with most severe consequences during early childhood. Acute and long-term manifestation of damaged heart tissue and disturbances of cardiac performance involve virus-triggered adverse activation of the immune response and both immunopathology, as well as, autoimmunity account for such immune-destructive processes. It is a matter of ongoing debate to what extent subclinical virus infection contributes to the debilitating sequela of the acute disease...

Incidence of Yellow Fever (YF) has increased in Brazil, and cardiac findings such as bradyarrhythmias and conduction abnormalities have been described. We aimed to perform a comprehensive cardiac evaluation of patients with YF, and to assess the association between cardiac involvement and disease severity. Patients hospitalized with YF from February to March 2018 underwent clinical and laboratory evaluation, focused bedside echocardiography (GE Vivid IQ), electrocardiogram and, in case of alterations, 24-hours Holter...

RATIONALE: The Epstein-Barr (EB) virus has rarely been reported as a cause of fulminant myocarditis. To our knowledge, the present case is the first report on myocardial calcification in EB viral myocarditis and rhabdomyolysis. PATIENT CONCERNS: A 17-year-old man was admitted to the department with fever, chest tightness, and tachypnea that had been present for 2 days. DIAGNOSES: The initial investigation showed elevated liver enzyme levels, creatine kinase levels, creatine kinase isoenzyme levels, and elevated serum myoglobin...

To date, aspirin desensitization is employed with patients with nonsteroidal anti-inflammatory drugs (NSAIDs) exacerbated respiratory diseases (NERD) or with aspirin or NSAIDs hypersensitive patients needing a stent procedure for coronary artery disease. On the other hand, few data exist regarding aspirin desensitization in other cardiological features and particularly we haven't data on different NSAIDs desensitization. Only for NERD patients we have data on ketorolac use. We report an efficacious desensitization procedure for ibuprofen in urticaria/angioedema patient with pericarditis and myocarditis associated...

A significant proportion of patients with acute myocarditis experience sudden cardiac death presumably due to cardiac arrhythmia. In this study, we explore the burden, the predictors of arrhythmia in acute myocarditis and the association between arrhythmias and adverse in-hospital outcomes. After evaluating the frequency of various tachyarrhythmias and bradyarrhythmia in myocarditis population, we built a logistic model to determine the independent predictors of arrhythmias in myocarditis and a 1:1 propensity-matched analysis to examine the impact of arrhythmias...

Marijuana is the most common drug of abuse in the United States. Marijuana has more than 460 active chemical compounds including δ-9- tetrahydrocannabinol (THC). It acts via the CB1 and CB2 receptors that are distributed in various tissues in the body. Marijuana is known to cause tachycardia, bradycardia, hypertension, to decrease time angina, myocardial infarction and cardiac arrest. Till date, four cases of myocarditis/perimyocarditis associated with marijuana use have been reported. In one such case, it led to the development of heart failure in a young male patient...

From April to September 2017, Bangladesh experienced a huge outbreak of acute Chikungunya virus infection in Dhaka. This series describes the clinical and laboratory features of a large number of cases (690; 399 confirmed and 291 probable) suffered during that period. This observational study was carried out at Dhaka Medical College Hospital, Bangladesh. The median age of the patients at presentation was 38 years (IQR 30-50) with a male (57.3%) predominance. Hypertension and diabetes were the most common comorbidities...

Autoimmune myocarditis often leads to dilated cardiomyopathy (DCM). Although T cell reactivity to cardiac self-antigen is common in the disease, it is unknown which antigen presenting cell (APC) triggers autoimmunity. Experimental autoimmune myocarditis (EAM) was induced by immunizing mice with α-myosin loaded bone marrow APCs cultured in GM-CSF. APCs found in such cultures include conventional type 2 CD11b+ cDCs (GM-cDC2s) and monocyte-derived cells (GM-MCs). However, only α-myosin loaded GM-cDC2s could induce EAM...

INTRODUCTION: Myocarditis has been described in association with many systemic immune-mediated diseases (SIDs). However, the role of SIDs in influencing clinical presentation and outcome of patients with a new diagnosis of biopsy-proved myocarditis, has never been investigated so far. METHODS: We enrolled 25 consecutive cases with biopsy-proved myocarditis in the context of SIDs, and controls with isolated myocarditis, matched 1:1 by age, gender, ethnicity and clinical presentation...

Objective: To survey the conduction and evaluate the effectiveness of extracorporeal membrane oxygenation (ECMO) therapy in pediatric intensive care unit (PICU) in China mainland. Methods: In a questionnaire-based survey, we retrospectively reviewed the application of ECMO in children's hospital and general hospital in China mainland to summarize and analyze the categories of diseases and prognosis of children treated with ECMO therapy. Results: By December 31, 2017, a total of 23 hospitals using ECMO, including 22 tertiary referral hospitals and 1 secondary hospital, among which 16 were children's hospitals and 7 were general hospitals...

Cardiorenal syndrome type 1 (CRS 1) occurs when acute heart failure leads to acute kidney injury. There are several etiologies of CRS 1, including Chagas disease. Here, we present the first case report of CRS 1 in a patient with acute Chagas disease. Electrocardiography, transthoracic echocardiography, and cardiac magnetic resonance imaging showed signs of acute myocarditis. Laboratory examination revealed severe loss of kidney function, with a creatinine clearance of 30 mL/min, which fully normalized after treatment...

BACKGROUND: Neonatal acute liver failure (ALF) is a severe condition with a mortality rate up to 70%. Human enterovirus (HEV) infections are associated with serious diseases in newborns, including myocarditis, meningoencephalitis and, more rarely, ALF with a fulminant course. METHODS: Cases of neonatal-onset ALF were identified using the institutional clinical database. The history and clinical data of infants with HEV infection were collected by medical record revision...

A 21-year-old woman was found to have fulminant myocarditis as a result of Coxsackie B infection (a virus shown to exhibit summer-fall seasonality) in mid-December. In this case report, seasonality of enteroviruses is examined, as well as additional factors which may contribute to sporadic cases during winter months. The case report also discusses clinical criteria for endomyocardial biopsy, utility of PCR vs. antibody serological tests, coinfection with multiple serotypes, and rhabdomyolysis in Coxsackie B...

Myocarditis can be caused by several infectious and noninfectious causes. Treatment for myocarditis is still a difficult task in clinical practice. The gut microbiota is related to cardiovascular diseases such as atherosclerosis and hypertension. However, little is known about the role of the gut microbiota in myocarditis. In our study, we tested the hypothesis that gut dysbiosis is associated with myocarditis. We focused on whether fecal microbiota transplantation (FMT) can be used as an effective treatment for myocarditis...

Background: Leptospirosis is a rare infectious illness caused by the Spirochaete Leptospira. It has a wide-varying spectrum of presentation. We present a rare case of severe cardiogenic shock secondary to leptospirosis, in the absence of its common clinical features. Case presentation: A 36-year-old woman presented to our unit with severe cardiogenic shock and subsequent multi-organ failure. Her clinical course was characterised by ongoing pyrexia of unknown origin with concurrent cardiac failure...

Myocarditis is mostly caused by viral infections and rarely caused by bacterial pathogens, especially in immunocompetent individuals. Bacterial myocarditis due to Salmonella is rare, especially in countries with improved sanitation that minimize contamination of Salmonella typhi serotypes. We here present a case of a previous healthy 22-year-old male that came to the emergency room with chest pain. His symptoms occurred after a period of profuse diarrhea, fever and hematochezia. Magnetic resonance imaging confirmed the diagnosis of myocarditis...
