varicella myocarditis

The varicella zoster virus (VZV) belongs to cardiotropic viruses, although the frequency of cardiac complications during VZV infection is low. Diagnosis of myocarditis or myopericarditis is rare during varicella - primary infection of VZV and sporadic in zoster - reactivation of latent VZV. Only few such cases have been described. The authors present a case of a 23-year-old male in whom clinical symptoms of myopericarditis developed a week after diagnosis of zoster that was localized in the left-upper part of the thorax...

A 12-year-old male child with Down syndrome, who had recovered from congenital heart disease, succumbed to severe varicella myocarditis. His clinical presentation at admission mimicked acute coronary syndrome. Analysis of this case throws insight into several aspects of varicella myocarditis.

Chickenpox is a common childhood infection caused by the varicella-zoster virus. Complications are rare. We report on a 15-year-old boy who developed myocarditis during a varicella-zoster infection. The patient presented with severe chest pain, examinations revealed significant ST-elevations in the electrocardiogram and elevated troponin T levels up to 690 ng/l. Echocardiography showed decreased left ventricular contractility without coinciding pericarditis. He remained haemodynamically stable on analgesics and aciclovir and was discharged nine days later with normalized echocardiography and troponin T levels...

A 23-year-old male was admitted with chest pain. The electrocardiogram showed ST elevation in leads DI, aVL, V2-V6. Troponin T was 1.1ng/mL. Left ventricular systolic function was globally reduced (ejection fraction 45%). The patient was treated with thrombolytic. Twenty-four hours after admission pruriginous vesicles with a clear content and surrounded by a pink halo appeared on his face, head and torso, suggesting varicella-zoster infection. This case illustrates the difficulties of diagnosis in acute myocarditis...

UNLABELLED: Aim of the study was to elucidate nosological nature of "idiopathic" arrhythmias by means of right ventricular endomyocardial biopsy (EMB) and to assess effect of etiotropic and pathogenetic treatment. MATERIAL AND METHODS: We included into this study 19 patients (mean age 42.6 +/-11.3 years, 9 women) with atrial fibrillation (AF, n = 16), supraventricular (n = 10) and ventricular (n = 4) extrasystoles (SVE and VE), supraventricular (n = 2) and ventricular (n = 1) tachycardia (SVT and VT), left bundle branch block (LBBB, n = 2), atrioventricular block (n = 2) without structural changes of the heart...

We present dramatic case of a 3 year-old boy who lost consciousness three weeks post Varicella Zoster virus infection. Cerebral edema was diagnosed with severe respiratory problems. Electrocardiogram showed transient but giant ST segment elevation, possibly secondary to brain damage.

Among unvaccinated populations, primary varicella zoster virus (VZV) infection results in a minor childhood illness for the majority of individuals. Mortality is rare, and fatalities associated with cardiac complications are exceptional. In a population where routine VZV vaccination is not practised, we report a death in a previously healthy child secondary to VZV myocarditis. A literature review of cardiac-related VZV mortality in childhood is included. This identified a further 13 cases where death was associated with or attributable to, direct involvement of the myocardium or conducting system with what is frequently considered a benign childhood illness...

Varicella (chickenpox), a common childhood infection caused by the varicella-zoster virus, is self-limiting and usually benign. Although atypical manifestations of the virus are occasionally seen, it rarely presents with cardiovascular sequelae. Cardiovascular complications of varicella can include pericarditis, myocarditis, or endocarditis. Herein, we report the case of a 17-year-old boy who had varicella infection and severe chest pain. Examination revealed atypical electrocardiographic findings of pericarditis and remarkably elevated cardiac biomarker levels: peak cardiac troponin I, 37...

Varicella is a common and mild disease in healthy children. However, when patients are in immunocompromised conditions, such as receiving chemotherapy for cancer treatment, they are highly vulnerable and it can even prove lethal. Herein, we report a 14-year-old boy with acute lymphoblastic leukemia who was receiving chemotherapy for induction with vincristine, idarubicin, L-asparaginase, and prednisolone, presented with typical varicella skin lesions and varicella-zoster virus was detected in his serum by real-time polymerase chain reaction (PCR)...

A young man presented to the emergency department with ventricular tachyarrhythmia later attributed to varicella zoster myocarditis. Myocarditis has an unpredictable clinical sequelae, making it a difficult condition to diagnose and manage in the emergency setting. The inconsistent clinical presentations, risks and management are demonstrated through a review of the literature.

Acute myopericarditis is a major cause of acquired heart disease worldwide in pediatric patients. Various viruses have been reported as the etiology, of which varicella zoster virus was first reported in 1953. However, since nationwide administration of the varicella vaccine, reports of varicella-associated myopericaridits have become sporadic. We report a case of varicella myopericarditis with an initial manifestation of chest pain, tachycardia, and hypotension. Typical skin vesicles developed 2 days after these symptoms, which confirmed the diagnosis...

More than 20 viruses have been reported to cause myopericarditis, a rare but potentially dangerous complication. To our best knowledge only a few dozen cases of myopericarditis caused by varicella zoster virus have been reported, most frequently in children, seldom in immunocompetent adults. We report on a case of a myopericarditis caused by varicella zoster virus in a previously healthy young man, with a typical development and a fast and complete recovery. A 27-years-old male was admitted to our hospital with chest pain and signs of acute cardiac injury...

Chickenpox is one of the most common infectious diseases in children. In most of the cases the disease is mild and no complications of it are being observed. However, in some of the paediatric patients, the disease may have a serious course with different complications. Most of them are not life-threatening, but some of them, like myocarditis, hepatitis or thrombocytopenia, may be dangerous. Neurological complications of Varicella-zoster virus infection, like encephalitis, meningitis, transverse myelitis, cerebellitis, polyneuropathy or an ischemic stroke, are relatively rare...

AIM: Although varicella is acknowledged as a rare cause of death in children, there are few comprehensive data with respect to the clinical course leading to death. METHODS: A nationwide, active surveillance was carried out in Germany for children up to age 17 years who were admitted to a paediatric hospital for varicella or associated complications, including deaths. RESULTS: A total of 10 children with varicella-associated death were reported over period of 2 years, yielding a mortality rate of 0...

A sixteen-year-old male presented with symptoms and investigations suggestive of acute myocardial infarction. The patient had suffered from a varicella zoster infection 5 days prior to presentation. Varicella myocarditis was suspected and diagnosed following treatment and positive varicella serology. This case highlights a rare but serious cardiac presentation of a common condition.

OBJECTIVES: To highlight clinical features and outcome of acute fulminant myocarditis (AFM) in children. METHODS: Diagnostic criteria were (1) the presence of severe and acute heart failure; (2) left ventricular dysfunction on echocardiography; (3) recent history of viral illness; and (4) no history of cardiomyopathy. RESULTS: Eleven children were included between 1998 and 2003, at a median age of 1 (0 to 9) year. Their mean left ventricular ejection fraction (LVEF) was 22 (SD 9)% at presentation...

Enteroviruses and other cardiotropic viruses have been associated with the development of late severe adverse cardiac events in infants receiving heart transplants. However, the source and the chronology of cardiac allograft infection by an enterovirus in patients receiving heart transplants remain unknown. Using RT-PCR and immunohistochemistry assays, endomyocardial tissue samples of 30 adult patients were tested to detect the presence of specific enterovirus 5' non-coding (5'NC) sequences and of VP1 capsid protein, and this at the time of cardiac transplantation and at the 12-month biopsy for graft rejection control...

A 29-year-old man presented with symptoms suggestive of acute pancreatitis of 3 day's duration. No definite aetiology was identifiable at admission. The patient had been receiving corticosteroids for the preceding 1 month, after the evacuation of a traumatic subdural haematoma. During the hospital stay, he developed a macular skin rash, which evolved over a period of 48 hours to a papulovesicular rash typical of varicella infection. Liver function tests were suggestive of anicteric hepatitis. Acyclovir therapy was instituted...

Enteroviruses have been implicated in the pathogenesis of idiopathic dilated cardiomyopathy (IDC). Recently, the association of adenovirus or parvovirus with IDC has been reported. Viral infection in the myocardium of American and Japanese patients with end-stage IDC was evaluated. Myocardial specimens from 30 American patients with IDC and 47 Japanese patients with IDC were analyzed for the presence of cardiotropic viruses. The strand-specific detection of enteroviral ribonucleic acid (RNA) was performed to determine viral activity in hearts with IDC...
