Myocarditis, hepatitis, and pancreatitis in a patient with coxsackievirus A4 infection: a case report

Changing Epidemiology of Hand, Foot, and Mouth Disease Causative Agents and Contributing Factors

Hand, foot, and mouth disease (HFMD) is a common viral infection primarily affecting children. It causes vesicles on the skin and inside the mouth. Although most cases get better on their own, severe cases can lead to complications such as brain stem encephalitis, meningoencephalitis, acute flaccid paralysis, and pulmonary edema. Hand, foot, and mouth disease is caused by various enteroviruses, with enterovirus A71 (EV-A71) and coxsackievirus A16 being the most common. However, recent studies have shown a shift in the molecular epidemiology of HFMD-causing pathogens, with coxsackievirus A6 and coxsackievirus A10 causing more infections. In addition, extensive recombination events have been identified among enterovirus strains, which may have a role in faster evolution and extinction of dominant enterovirus serotypes. Other strains of enterovirus can also cause severe complications, and there has been an increase in mortality associated with brain stem encephalitis in children under 3 years of age and teenagers. Currently, there are no effective antiviral therapies available to treat enterovirus infections. Vaccines against EV-A71 have been approved and are now used in mainland China. Studying the changing epidemiology of HFMD pathogens and the evolution patterns of its causative agents is crucial in developing effective prevention and control strategies. Increased interest in the molecular epidemiology of HFMD causative agents has led to a better understanding of the critical drivers of HFMD outbreaks, which can inform efforts to prevent and control the disease.

Global landscape of coxsackieviruses in human health

Coxsackieviruses-induced infections, particularly in infants and young children, are one of the most important public health issues in low- and middle-income countries, where the surveillance system varies substantially, and these manifestations have been disregarded. They are widespread throughout the world and are responsible for a broad spectrum of human diseases, from mildly symptomatic conditions to severe acute and chronic disorders. Coxsackieviruses (CV) have been found to have 27 identified genotypes, with overlaps in clinical phenotypes between genotypes. In this review, we present a concise overview of the most recent studies and findings of coxsackieviruses-associated disorders, along with epidemiological data that provides comprehensive details on the distribution, variability, and clinical manifestations of different CV types. We also highlight the significant roles that CV infections play in the emergence of neurodegenerative illnesses and their effects on neurocognition. The current role of CVs in oncolytic virotherapy is also mentioned. This review provides readers with a better understanding of coxsackieviruses-associated disorders and pointing the impact that CV infections can have on different organs with variable pathogenicity. A deeper knowledge of these infections could have implications in designing current surveillance and prevention strategies related to severe CVs-caused infections, as well as encourage studies to identify the emergence of more pathogenic types and the etiology of the most common and most severe disorders associated with coxsackievirus infection.

Novel pathologic findings and viral antigen distribution in cattle and buffalo calves naturally infected with Foot-and-Mouth disease virus

The Foot-and-Mouth disease is highly contagious acute viral disease of livestock inflicting huge economic loss to the farmers. The limited knowledge regarding the pathological lesions vis-a-vis distribution of the FMDV in lesser explored endocrine glands and important vital organs other than the target organs of infected calves prompted us to take the present investigation to have detailed insight into the pathogenesis. The systematic necropsy of 37 dead calves (cattle-28 and buffalo-9) was conducted, and thin representative tissue pieces from the affected organs were collected in 10% neutral buffered formalin (NBF) for pathological and immunohistochemical investigations. The genomic detection and its serotyping were done by RT-PCR and multiplex-PCR, respectively. Necropsy examination in all cases showed myocardial lesions resembling 'tigroid heart appearance'. Other organ specific lesions include vesiculo-ulcerative stomatitis, edema of the lungs, petechial hemorrhages, edema of the endocrines, and gastroenteritis. Histopathological examination showed varying sizes of vesicles and ulcerations in stratified squamous epithelium of the tongue, acute necrotizing myocarditis, lymphoid depletion in lymphoid tissues, hepatitis, pancreatitis, thymic hyperplasia, thyroiditis, adrenitis, and enteritis. Positive immunolabeling for viral antigens was observed in endocrine glands, lymphoid organs, lungs, liver, kidneys, and intestine, in addition to other typical locations. The thyroid, adrenal glands, and pancreas, in addition to the tongue and heart, are the tissue of choice for sampling in the field during epidemics. Further, the viral genome and serotype A was confirmed in the affected tissues. This study provides insights into novel tissue tropism and pathogenesis in young calves naturally infected with FMDV.

Transient constrictive pericarditis following coxsackievirus A4 infection as a rare cause of acute mediastinitis: A case report

Background

Transient constrictive pericarditis (TCP) is a distinct constrictive pericarditis (CP) subtype characterized by acute pericardial inflammation and transient constrictive physiology. If left untreated, it may progress to irreversible CP requiring pericardiectomy. However, making an early diagnosis of TCP remains difficult.

Case presentation

A 51-year-old man presented with fever, chest pain, and dyspnea following preceding flu symptoms. An initial investigation suggested right-sided heart failure. Laboratory results revealed elevated inflammatory markers and hepatic enzyme levels. Echocardiography revealed pericardial effusion with a normal ejection fraction and diastolic ventricular septal bounce suggestive of pericardial constriction. Computed tomography suggested acute descending mediastinitis with pericarditis and pleuritis; however, detailed examinations ruled out this possibility. The constellation of increased serological inflammation, pericardial thickness/effusion, and constrictive physiology suggested TCP, confirmed by cardiac magnetic resonance (CMR) and hemodynamic studies. CMR also revealed coexistent myocarditis. After a thorough assessment for the cause of TCP, a viral etiology was suspected. Paired serology for virus antibody titers revealed a significant increase only in coxsackievirus A4 (CVA4) titers. With prompt anti-inflammatory treatment, the patient's pericardial structure and function and concomitant inflammation of the surrounding tissues were nearly completely recovered, leading to a final diagnosis of TCP caused by CVA4. The subsequent clinical course was uneventful without recurrence at the 1-year follow-up.

Conclusions

Here we described the first case of TCP caused by CVA4 concurrent with mediastinitis, myocarditis, and pleuritis, all of which were successfully resolved with anti-inflammatory treatment. Acute mediastinitis secondary to TCP is rare. This case highlights the clinical importance of assessing pericardial diseases as a source of acute mediastinitis and considering CVA4 as an etiology of TCP. An evaluation including multimodal cardiac imaging and serology for virus antibody titers may be useful for an exploratory diagnosis of TCP in right-sided heart failure patients with pericardial effusion.

Molecular Characteristics of Enterovirus B83 Strain Isolated from a Patient with Acute Viral Myocarditis and Global Transmission Dynamics

This study determined the global genetic diversity and transmission dynamics of enterovirus B83 (EV-B83) and proposed future disease surveillance directions. Blood samples were collected from a patient with viral myocarditis, and viral isolation was performed. The complete genome sequence of the viral isolate was obtained using Sanger sequencing. A dataset of 15 sequences (from three continents) that had sufficient time signals for Bayesian phylogenetic analysis was set up, and the genetic diversity and transmission dynamics of global EV-B83 were analyzed using bioinformatics methods, including evolutionary dynamics, recombination event analysis, and phylogeographic analysis. Here, we report the complete genome sequence of an EV-B83 strain (S17/YN/CHN/2004) isolated from a patient with acute viral myocarditis in Yunnan Province, China. All 15 EV-B83 strains clustered together in a phylogenetic tree, confirming the classification of these isolates as a single EV type, and the predicted time for the most recent common ancestor appeared in 1998. Recombinant signals were detected in the 5'-untranslated region and 2A-3D coding regions of the S17 genome. The phylogeographic analysis revealed multiple intercontinental transmission routes of EV-B83. This study indicates that EV-B83 is globally distributed. Our findings add to the publicly available EV-B83 genomic sequence data and deepen our understanding of EV-B83 epidemiology.

An outbreak of a novel recombinant Coxsackievirus A4 in a kindergarten, Shandong Province, China, 2021

In 2021, twenty children exhibiting influenza-like illnesses were reported from a kindergarten in Shandong Province, China. Eleven genomes of Coxsackievirus A4 (CV-A4) were obtained from the pediatric cases, sharing <93% genome sequence identities with known CV-A4 strains. Further analyses suggested potential genetic recombination in the P3 region of the novel strains.

Viral-Attributed Acute Pancreatitis: A Systematic Review

Infectious etiologies are rare cause of acute pancreatitis (AP). We sought to investigate the frequency of viral-attributed AP (VIAP) and describe its natural course and clinical features. Comprehensive review of PubMed and EMBASE in English until December 31, 2019, was performed. AP diagnosis and severity were defined per the Revised Atlanta Classification. Viral infections were diagnosed by serology and/or histology. A diagnosis of viral infection, with a concurrent AP diagnosis, a temporal resolution of both entities, and the attempt to exclude the most common etiologies of AP defined VIAP. Two independent reviewers reviewed eligible publications. Bias risk was assessed with the Murad tool. A total of 209 cases identified in 128 publications met inclusion criteria. Mean age was 38.9 ± 1.28 years. Male-to-female ratio was 2.2:1, and 28% of patients were immunocompromised. Viral hepatitis (A, B, C, D and E) was the most common virus and accounted for 34.4% of cases, followed by coxsackie and echoviruses (14.8%), hemorrhagic fever viruses (12.4%), CMV (12.0%), VZV (10.5%), mumps and measles (3.8%), primary HIV infection (3.8%), HSV (1.9%), EBV (1.9%), and the remainder of cases (2.9%) attributed to adenovirus, influenza H1N1, and multiple viruses. Severity of AP was: 43.1% mild, 11.7% moderately severe, 32.4% severe. Death occurred in 42 (20.1%) patients. A significant portion of VIAP patients were immunocompromised (28.0%) and accounted for 71.4% of mortality cases. Mortality was higher than that reported for AP from other etiologies in the literature.

Viral meningitis: an overview

Meningitis is a serious condition that affects the central nervous system. It is an inflammation of the meninges, which is the membrane that surrounds both the brain and the spinal cord. Meningitis can be caused by bacterial, viral, or fungal infections. Many viruses, such as enteroviruses, herpesviruses, and influenza viruses, can cause this neurological disorder. However, enteroviruses have been found to be the underlying cause of most viral meningitis cases worldwide. With few exceptions, the clinical manifestations and symptoms associated with viral meningitis are similar for the different causative agents, which makes it difficult to diagnose the disease at early stages. The pathogenesis of viral meningitis is not clearly defined, and more studies are needed to improve the health care of patients in terms of early diagnosis and management. This review article discusses the most common causative agents, epidemiology, clinical features, diagnosis, and pathogenesis of viral meningitis.

Infectious causes of acute pancreatitis: A systematic review

BACKGROUND

Infectious etiologies of acute pancreatitis (AP) are rare and include viruses, bacteria, mycobacteria, parasites, and fungi. We aimed to conduct a comprehensive review on infectious etiologies of AP analyzing the frequency, clinical features, and outcomes of individuals presenting with this condition.

METHODS

Eligible articles reporting on AP attributed to infectious etiologies were included. A comprehensive literature search of PubMed from time of inception and until September 6,2019 was performed using all relevant MeSH (medical subject heading) keywords. Articles were assessed for eligibility and independently reviewed by two reviewers for clinical features of AP, local complications, and mortality. Methodological quality of included studies was evaluated using the Murad tool.

RESULTS

A total of 212 articles were included, of which 168 (79.2%) were at high risk of bias. 320 cases of AP were identified. Viruses were the leading etiology of infection attributed AP (65.3%) followed by helminths (19.1%), and bacteria (12.5%). Protozoa, mycobacteria, and fungi accounted for the remaining 3.1% of cases. Mean age was 40.5 ± 18.4 years and M:F ratio was 1.94:1. Mortality occurred in 50 patients. Mortality rate was higher in the virus attributed AP patients than AP from other infectious etiologies (21.8% vs. 7.0%, p < 0.0005).

INTERPRETATION

Literature quality on infection attributed AP is limited. Virus attributed AP appears to carry a higher mortality than other etiologies of infection attributed AP.

A rare case of fulminant type 1 diabetes mellitus accompanied by both acute pancreatitis and myocarditis - case report

BACKGROUND

Fulminant type 1 diabetes mellitus (FT1D) is a newly established subtype of type 1 diabetes. Its etiology has not been fully elucidated. Several cases with FT1D have exhibited pancreatitis or myocarditis.

CASE PRESENTATION

We report a 31-year-old Japanese woman who showed upper abdominal pain and was admitted to a local hospital. She was initially diagnosed with acute pancreatitis based on serum amylase elevation and swelling of the pancreas on computed tomography. Four days after admission, she developed diabetic ketoacidosis and was transferred to our hospital. Her symptoms and laboratory findings met the FT1D criteria. On the 3rd hospital day, electrocardiography (ECG) showed ST-segment elevation, and serum cardiac enzymes were markedly elevated. Because she exhibited late gadolinium enhancement in the apical wall on contrast-enhanced cardiac magnetic resonance imaging, she was diagnosed as acute myocarditis. Abnormal ECG findings and elevations of biomarkers associated with myocarditis showed improvement on the next day.

CONCLUSIONS

This is the first case of FT1D accompanied by both pancreatitis and myocarditis and suggests that the pathophysiology of FT1D is related to the common etiology of acute pancreatitis and myocarditis.

A neonatal murine model of coxsackievirus A4 infection for evaluation of vaccines and antiviral drugs

Coxsackievirus A4 (CVA4) infection can cause hand, foot and mouth disease (HFMD), an epidemic illness affecting neonatal and paediatric cohorts, which can develop to severe neurological disease with high mortality. In this study, we established the first ICR mouse model of CVA4 infection for the evaluation of inactivated vaccines and antiviral drug screening. The CVA4 YT226R strain was selected to infect the neonatal mice and three infectious factors were optimized to establish the infection model. The 3-day-old neonatal mice exhibited clinical symptoms such as hind limb paralysis and death. The severe inflammatory reactions were closely related to the abnormal expression of the acute phase response proinflammatory cytokine IL-6 and an imbalance in the IFN-γ/IL-4 ratio. Importantly, the inactivated CVA4 whole-virus vaccine induced humoral immune responses in adult females and the maternal antibodies afforded mice complete protection against lethal dose challenges of homologous or heterologous CVA4 strains. Both IFN-α2a and antiserum inhibited the replication of CVA4 and increased the survival rates of neonatal mice during the early stages of infection. This neonatal murine model of CVA4 infection will be useful for the development of prophylactic and therapeutic vaccines and for screening of antiviral drugs targeting CVA4 to decrease morbidity and mortality.

Emerging recombination of the C2 sub-genotype of HFMD-associated CV-A4 is persistently and extensively circulating in China

Sporadic outbreaks caused by coxsackievirus A4 (CV-A4) have been reported worldwide. To further elucidate the detailed genetic characteristics and evolutionary recombination events of CV-A4, virus samples from nationwide hand, foot and mouth disease (HFMD) surveillance, encompassing 27 out of the 31 provinces in China, were investigated. Comprehensive and systematic phylogenetic analyses were performed by using 29 complete genomes, 142 complete CV-A4 VP1 sequences. Four genotypes (A, B, C and D) and five sub-genotypes (C1-C5) were re-identified based on the complete VP1 sequences. C2 is the predominant sub-genotype of CV-A4 associated with HFMD and has evolved into 3 clusters. Cluster 1 is a major cluster that has been persistently and extensively circulating in China since 2006 and has been associated with all severe cases. All the sequences showed high homology with the CV-A4 prototype in the P1 region, while higher identities with CV-A5, CV-14 and CV-16 in the P2 and P3 regions. Recombination analysis revealed that C2 had two specific genetic recombination patterns with other EV-A prototypes in the 5'-UTR and 3D region compared with C5. These recombination patterns might be associated with the increased transmissibility of C2 viruses, which were obtained due to their persistent and extensive circulation in populations.

Coxsackie B2 Virus Infection Causing Multiorgan Failure and Cardiogenic Shock in a 42-Year-Old Man

Infections from coxsackie B2 viruses often cause viral myocarditis and, only rarely, multisystem organ impairment. We present the unusual case of a 42-year-old man in whom coxsackie B2 virus infection caused multiorgan infection, necessitating distal pancreatectomy, splenectomy, renal dialysis, and venoarterial extracorporeal membrane oxygenation with mechanical ventilation. In addition, the patient had a rapid-eye-movement sleep-related conduction abnormality that caused frequent sinus pauses of longer than 10 s, presumably due to myocarditis from the coxsackievirus infection. He recovered after permanent pacemaker placement and was discharged from the hospital. We discuss our aggressive supportive care and the few other reports of multiorgan impairment from coxsackieviruses.

A case report of myocarditis combined with hepatitis caused by herpes simplex virus

BACKGROUND

Viral myocarditis presents with various symptoms, including fatal arrhythmia and cardiogenic shock, and may develop into chronic myocarditis and dilated cardiomyopathy in some patients. We report a case of viral myocarditis and hepatitis caused by herpes simplex virus.

CASE PRESENTATION

A 20-year-old woman was admitted to our hospital with fever, fatigue, and anorexia. The initial investigation showed elevated liver enzyme levels and elevated creatine phosphokinase, and computed tomography showed diffuse swelling and internal heterogeneous image in the liver. These findings were consistent with acute hepatitis; therefore, we performed a liver biopsy, which showed parenchymal necrosis and lymphocytic infiltration. The night that the liver biopsy was performed, blood pressure gradually decreased and revealed cardiogenic shock. Electrocardiography showed diffuse ST-segment elevation, and echocardiography showed a dilated, spherical ventricle with reduced systolic function and pericardial effusion. An endomyocardial biopsy revealed lymphocyte infiltration of the myocardium, confirming acute myocarditis. After a few days, tests for immunoglobin M and immunoglobin G antibodies against herpes simplex virus were positive.

CONCLUSIONS

We presented a rare case of myocarditis combined with hepatitis that was caused by herpes simplex virus. Acute myocarditis can occur concurrently with hepatitis, pancreatitis, nephritis, and encephalitis; thus, determining the presence of other infectious lesions is necessary to provide appropriate treatment for the patient.

Pancreatitis and myocarditis coexistence due to infection by Coxsackie B1 and B4 viruses

Myocarditis can be a rare late manifestation of acute pancreatitis caused by Coxsackie virus infection. Clinicians should be aware of potentially life-threatening myocarditis because immediate recognition and management are the cornerstones in achieving a better outcome.

Acute pancreatitis in hand, foot and mouth disease caused by Coxsackievirus A16: case report

Coxsackievirus A16 (CA16), which primarily causes hand, foot, and mouth disease (HFMD), is associated with complications, such as encephalitis, acute flaccid paralysis, myocarditis, pericarditis, and shock. However, no case of pancreatitis associated with CA16 has been reported in children. We report a case of CA16-associated acute pancreatitis in a 3-year-old girl with HFMD. She was admitted because of poor oral intake and high fever for 1 day. Maculopapular rashes on both hands and feet and multiple vesicles on the soft palate were observed on physical examination. She was treated conservatively with intravenous fluids. On the fourth hospital day, she had severe abdominal pain and vomiting. The serum levels of amylase and lipase were remarkably elevated (amylase, 1,902 IU/L; reference range, 28–100 IU/L; lipase, >1,500 IU/L; reference range, 13–60 IU/L), and ultrasonography showed diffuse swelling of the pancreas with a small amount of ascites. The real-time reverse transcription polymerase chain reaction result from a stool sample was positive for CA16. CA16 can cause acute pancreatitis, and should be considered in the differential diagnosis of abdominal pain in children with HFMD.

Multiple transmission chains of coxsackievirus A4 co-circulating in China and neighboring countries in recent years: Phylogenetic and spatiotemporal analyses based on virological surveillance

Coxsackievirus A4 (CV-A4) has been reported frequently in association with many infectious diseases and cases of hand, foot, and mouth disease potentially associated with CV-A4 infection are also identified. This study summarized the Shandong CV-A4 strains isolated from 25years acute flaccid paralysis surveillance, with an emphasis on exploring the phylogenetic analyses and spatiotemporal dynamics of CV-A4 at the global scale. We sampled 43 CV-A4 isolates and utilized VP1 gene to construct phylogenetic trees. Further extensive Bayesian phylogeographic analysis was carried out to investigate the evolution of CV-A4 and understand the spatiotemporal diffusion around the world using BEAST and SPREAD software. Phylogenetic trees showed that CV-A4 emerged to be more active in recent decades and multiple transmission chains were co-circulating. The molecular clock analysis estimated a mean evolutionary rate of 6.4×10^-3 substitutions/site/year, and the estimated origin of CV-A4 around 1944. The phylogeographic analyses suggested the origin of CV-A4 could be in the USA, however regional dissemination was mainly located around the Asia-Europe region. The spatiotemporal dynamics of CV-A4 exhibited frequent viral traffic among localities, and virus from Shandong province seemed to have played a central role in spreading around China and neighboring countries. Our phylogenetic description and phylogeographic analyses indicate the importance of large spatial- and temporal-scale studies in understanding epidemiological dynamics of CV-A4, particularly the diffusion routes will be of great importance to global control efforts.

Echovirus 6 Infects Human Exocrine and Endocrine Pancreatic Cells and Induces Pro-Inflammatory Innate Immune Response

Human enteroviruses (HEV), especially coxsackievirus serotype B (CVB) and echovirus (E), have been associated with diseases of both the exocrine and endocrine pancreas, but so far evidence on HEV infection in human pancreas has been reported only in islets and ductal cells. This study aimed to investigate the capability of echovirus strains to infect human exocrine and endocrine pancreatic cells. Infection of explanted human islets and exocrine cells with seven field strains of E6 caused cytopathic effect, virus titer increase and production of HEV protein VP1 in both cell types. Virus particles were found in islets and acinar cells infected with E6. No cytopathic effect or infectious progeny production was observed in exocrine cells exposed to the beta cell-tropic strains of E16 and E30. Endocrine cells responded to E6, E16 and E30 by upregulating the transcription of interferon-induced with helicase C domain 1 (IF1H1), 2′-5′-oligoadenylate synthetase 1 (OAS1), interferon-β (IFN-β), chemokine (C–X–C motif) ligand 10 (CXCL10) and chemokine (C–C motif) ligand 5 (CCL5). Echovirus 6, but not E16 or E30, led to increased transcription of these genes in exocrine cells. These data demonstrate for the first time that human exocrine cells represent a target for E6 infection and suggest that certain HEV serotypes can replicate in human pancreatic exocrine cells, while the pancreatic endocrine cells are permissive to a wider range of HEV.

Effusive-constrictive pericarditis, hepatitis, and pancreatitis in a patient with possible coxsackievirus B infection: a case report

BACKGROUND

Coxsackie B is a viral pathogen that presents with various invasive diseases in adults. Historically, the majority of adult cases with pericarditis or myocarditis have been attributed to coxsackievirus B. The presentation of this viral infection causing effusive-constrictive pericarditis, hepatitis or pancreatitis is rare. This case report is the first to describe a patient with concomitant effusive-constrictive pericarditis, hepatitis and pancreatitis from possible coxsackievirus B infection.

CASE PRESENTATION

A 26-year old female was admitted to our hospital with the diagnosis of effusive-constrictive pericarditis complicated by tamponade and cardiac arrest. An emergent pericardiocentesis was performed successfully. Hepatitis and pancreatitis were also identified in our patient. After an extensive workup, coxsackievirus B infection was suspected by positive serum complement fixation antibody titers. Our patient made a full recovery and was discharged from the hospital.

CONCLUSION

Clinical suspicion of effusive-constrictive pericarditis with tamponade from coxsackievirus B should be considered in patients presenting with chest pain, dyspnea, jugular venous distention, hypotension, ST segment elevation on electrocardiogram, and ventricular interdependence with septal shift during diastole on transthoracic echocardiogram. Initial diagnoses of effusive-constrictive pericarditis resembling cardiac tamponade, hepatitis and pancreatitis can be challenging, and this case highlights the need for healthcare professionals to be cognizant of the association between these unusual clinical presentations and coxsackievirus B infection.

Pancreatitis in hand-foot-and-mouth disease caused by enterovirus 71

Some viruses, including certain members of the enterovirus genus, have been reported to cause pancreatitis, especially Coxsackie virus. However, no case of human enterovirus 71 (EV71) associated with pancreatitis has been reported so far. We here report a case of EV71-induced hand-foot-and-mouth disease (HFMD) presenting with pancreatitis in a 2-year-old girl. This is the first report of a patient with acute pancreatitis in HFMD caused by EV71. We treated the patient conservatively with nasogastric suction, intravenous fluid and antivirals. The patient’s symptoms improved after 8 d, and recovered without complications. We conclude that EV71 can cause acute pancreatitis in HFMD, which should be considered in differential diagnosis, especially in cases of idiopathic pancreatitis.

Acute viral hepatitis e is associated with the development of myocarditis

Myocarditis, an inflammatory disease of heart muscle, is an important cause of dilated cardiomyopathy worldwide. Viral infection is an important cause of myocarditis. This condition presents with various symptoms, ranging from minimally symptomatic cases to fatal arrhythmia and cardiogenic shock, and may develop chronic myocarditis and dilated cardiomyopathy in some patients. We report the case of a 26-year-old patient with acute viral hepatitis E who developed symptomatic myocarditis. As far as we could search, this is probably the 3rd case report of this rare association.
