Leung AKC, Lam JM, Barankin B, Leong KF, Hon KL. Erythema Infectiosum: A Narrative Review. Curr Pediatr Rev 2024; 20:462-471. [PMID: 37132144 DOI: 10.2174/1573396320666230428104619] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 02/27/2023] [Accepted: 02/28/2023] [Indexed: 05/04/2023]
Abstract
BACKGROUND Erythema infectiosum occurs worldwide. School-aged children are most often affected. Since the diagnosis is mainly clinical, physicians should be well-versed in the clinical manifestations of erythema infectiosum to avoid misdiagnosis, unnecessary investigations, and mismanagement of the disease. OBJECTIVES The purpose of this article is to familiarize physicians with the wide spectrum of clinical manifestations and complications of erythema infectiosum associated with parvovirus B19 infection. METHODS A search was conducted in July 2022 in PubMed Clinical Queries using the key terms "Erythema infectiosum" OR "Fifth disease" OR "Slapped cheek disease" OR "Parvovirus B19". The search strategy included all clinical trials, observational studies, and reviews published within the past 10 years. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of the present article. RESULTS Erythema infectiosum is a common exanthematous illness of childhood caused by parvovirus B19. Parvovirus B19 spreads mainly by respiratory tract secretions and, to a lesser extent, the saliva of infected individuals. Children between 4 and 10 years of age are most often affected. The incubation period is usually 4 to 14 days. Prodromal symptoms are usually mild and consist of lowgrade fever, headache, malaise, and myalgia. The rash typically evolves in 3 stages. The initial stage is an erythematous rash on the cheeks, with a characteristic "slapped cheek" appearance. In the second stage, the rash spreads concurrently or quickly to the trunk, extremities, and buttocks as diffuse macular erythema. The rash tends to be more intense on extensor surfaces. The palms and soles are typically spared. Central clearing of the rash results in a characteristic lacy or reticulated appearance. The rash usually resolves spontaneously within three weeks without sequelae. The third stage is characterized by evanescence and recrudescence. In adults, the rash is less pronounced than that in children and is often atypical. Only approximately 20% of affected adults have an erythematous rash on the face. In adults, the rash is more frequently found on the legs, followed by the trunk, and arms. A reticulated or lacy erythema is noted in 80% of cases which helps to distinguish erythema infectiosum from other exanthems. Pruritus is noted in approximately 50% of cases. The diagnosis is mainly clinical. The many manifestations of parvovirus B19 infection can pose a diagnostic challenge even to the best diagnostician. Complications include arthritis, arthralgia, and transient aplastic crisis. In most cases, treatment is symptomatic and supportive. When parvovirus B19 infection occurs in pregnant women, hydrops fetalis becomes a real concern. CONCLUSION Erythema infectiosum, the most common clinical manifestation of parvovirus B19 infection, is characterized by a "slapped cheek" appearance on the face and lacy exanthem on the trunk and extremities. Parvovirus B19 infection is associated with a wide spectrum of clinical manifestations. Physicians should be aware of potential complications and conditions associated with parvovirus B19 infection, especially in individuals who are immunocompromised, chronically anemic, or pregnant.

Abstract
BACKGROUND There are no optimal diagnostic, treatment and post-infection surveillance strategies for parvovirus B19 infection in solid organ transplantation (SOT) recipients. METHODS We conducted a retrospective review of all PVB19 infected cases confirmed by qPCR among SOT recipients at our institution over a 3-year period and reviewed the literature from 1990 to 2021. RESULTS Eight kidney and two heart transplant patients with refractory anemia had PVB19 infection. The viral DNA load in peripheral blood ranged from 2.62 × 102 to 8.31 × 106 copies/mL. Two patients with the lowest PVB19 DNA load only reduced the use of immunosuppressants and anemia was relieved. Eight received intravenous immunoglobulin (IVIG) (ranging from 0.25 to 0.5 g/kg/day). The median time to anemia improvement (hemoglobulin>100g/L) was 16 days (8-70 days) after treatment. One patient had a PVB19 relapse and viral DNA load > 1.00 × 108 copies/mL at diagnosis. A total of 86 studies involving 194 SOTs were screened from the literature, and the most common symptom was anemia and low reticulocyte count. PVB19 DNA was detected in all cases. Of that, 91.4% of cases received IVIG, 53.8% received IVIG and immunosuppression reduction, 6.5% of cases showed reduced immunosuppression without IVIG, and 2.1% did not receive any special treatment. The recurrence rate was 17.5%. CONCLUSION PVB19 infection is a cause of anemia after SOT, and treatment mainly relies on IVIG and/or immunosuppression reduction.

Abstract
Classic "bread-and-butter" appearance of fibrinous pericarditis had been described in rheumatic disease and other immunologic diseases such as systemic lupus erythematosus, post-myocardial infarct, uremia, tuberculosis, radiation effects, bacterial, and viral etiology. In most of the described cases, pericarditis occurs as a delayed complication. We present a case of a 21-year-old white woman who was seen in the emergency department to rule out pulmonary embolism for shortness of breath, chest pain, and lightheadedness. The autopsy showed a collection of serous fluid into the pericardial sac with bread-and-butter appearance. Microscopically, the pericardium showed acute inflammation with fibrinous exudates. Sections of the heart showed areas of lymphocytic infiltration with acute fibrinous inflammation of the pericardium. Vasculitis was seen in small blood vessels in the heart and was negative in other organs. No granuloma or necrotizing lesion was seen in microscopic sections of all organs including the heart, ruling out rheumatologic disease. The present study highlights the quest and design of an algorithm for a nonrheumatic disorder as the cause of pericarditis. Molecular studies were performed on heart tissue blocks for identification of cardiotropic viruses. Human parvovirus B19 was isolated from heart tissue blocks. The present case study highlights on updates in pathophysiology and diagnostic criteria for myocarditis along with the use of new molecular techniques for detection of idiopathic cardiomyopathies in a medical examiner setup.

Abstract
Parvovirus B19 (B19V) and human bocavirus 1 (HBoV1), members of the large Parvoviridae family, are human pathogens responsible for a variety of diseases. For B19V in particular, host features determine disease manifestations. These viruses are prevalent worldwide and are culturable in vitro, and serological and molecular assays are available but require careful interpretation of results. Additional human parvoviruses, including HBoV2 to -4, human parvovirus 4 (PARV4), and human bufavirus (BuV) are also reviewed. The full spectrum of parvovirus disease in humans has yet to be established. Candidate recombinant B19V vaccines have been developed but may not be commercially feasible. We review relevant features of the molecular and cellular biology of these viruses, and the human immune response that they elicit, which have allowed a deep understanding of pathophysiology.

Abstract
The aetiology of pericardial effusion has been generally assessed by clinical work-up only, which leaves a large cohort of patients with "idiopathic" effusions virtually undiagnosed. In accordance with the ESC guidelines, this contribution intends to change this attitude. After therapeutic or diagnostic pericardiocentesis of 259 patients with large to moderate pericardial effusions, pericardial fluid, epicardial and pericardial biopsies, and blood samples were analysed by PCR for cardiotropic microbial agents. Cytology, histology, immunohistology of tissue and fluids and laboratory tests were performed. Of the 259 patients, 35 % suffered from an autoreactive aetiology, 28 % suffered from a malignant and 14 % from an infectious cause. Investigating all samples by PCR, we identified viral genomes in 51 (19.7 %) patients, parvovirus B19 (B19 V) being identified in 25 and Epstein-Barr virus (EBV) in 19 cases. In patients with a sole infectious aetiology (n = 36), B19 V was detected in 21 and EBV in 10 cases. When differentiating with regard to the material investigated for the presence of cardiotropic viruses, parvovirus B19 was most often detected in the epicardium and EBV was most frequently detected in the pericardial fluid independent from the final diagnostic categorisation. Bacterial cultures including tests for tuberculosis were all negative. Molecular techniques improve sensitivity, specificity and diagnostic accuracy for the underlying aetiology in pericarditis patients with effusion. The identification of specific viral signatures will help to understand pathogenetic mechanisms in pericarditis and allow to tailor an adequate therapy beyond antiphlogistic treatment.

Complete remission of human parvovirus b19 associated symptoms by loxoprofen in patients with atopic predispositions. Case Rep Med 2012; 2012:703281. [PMID: 22611409 PMCID: PMC3348632 DOI: 10.1155/2012/703281] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2012] [Revised: 03/14/2012] [Accepted: 03/16/2012] [Indexed: 01/17/2023] Open
Abstract
Two cases of women in their thirties with past histories of atopic dermatitis and allergic rhinitis developed a low grade fever, followed by a butterfly-shaped erythema, swelling of their fingers, and polyarthralgia. Despite such symptoms that overlap with those of systemic lupus erythematosus (SLE), the diagnostic criteria for SLE were not fulfilled. Due to positive results for human parvovirus B19 (HPV-B19) IgM antibodies in the serum, diagnoses of HPV-B19 infection were made in both cases. Although acetaminophen failed to improve their deteriorating symptoms, a nonsteroidal anti-inflammatory drug (NSAID), loxoprofen, completely removed the symptoms immediately after the administration. In those cases, since the patients were predisposed to atopic disorders, an increased immunological response based on the lymphocyte hypersensitivity was likely to be involved in the pathogenesis. The immunomodulatory property of NSAID was thought to repress such lymphocyte activity and thus provided a rapid and sustained remission of the disease.

Abstract
The clinical presentation of myocarditis is variable and can mimic myocardial infarction. The diagnosis of acute myocarditis is frequently empiric, and is made on the basis of the clinical presentation, electrocardiographic changes, elevated cardiac enzymes, and lack of epicardial coronary artery disease and lymphocytic infiltration on myocardial biopsy. We present an unusual case of a young patient with history of heart transplantation who presented with fever and polyarthritis and developed chest pain along with electrocardiographic changes and troponin elevation with no evidence of coronary artery disease. His myocardial biopsy revealed marked neutrophilic infiltration and no evidence of rejection. The clinical picture was compatible with a rare finding of neutrophilic myocarditis in the allograft, possibly related to a systemic inflammatory process.

Abstract
Background Histologically documented cases of parvoviral myocarditis are exceedingly rare. Case presentation Here, we report a 41-year old African American immunocompetent patient who died of parvoviral myocarditis after a 10 day illness characterized by fever, headaches, generalized arthralgias, and a maculopapular rash. Autopsy revealed an infiltrate myocarditis composed primarily of T-lymphocytes and macrophages associated with extensive myocardial fibrosis. The diagnosis of parvovirus was determined by polymerase chain reaction (PCR) on both pre-mortem serum and post-mortem myocardial tissue Methods DNA was extracted from tissue and serum and primers were used to amplify DNAsequences of parvovirus B19 using nested polymerase chain reaction (PCR). Conclusion The diagnosis of parvovirus should be considered in cases of fatal myocarditis, and diagnosis can be confirmed at autopsy by molecular techniques.

Abstract
Human parvovirus B19 is a minute ssDNA virus that causes a wide variety of diseases, including erythema infectiosum, arthropathy, anemias and fetal death. In addition to the B19 prototype, two new variants (B19 types 2 and 3) have been identified. After primary infection, B19 genomic DNA has been shown to persist in solid tissues of not only symptomatic but also of constitutionally healthy, immunocompetent individuals. The viral DNA persists as an intact molecule without persistence-specific mutations, and via a storage mechanism with life-long capacity. Thus, the mere presence of B19 DNA in tissue cannot be used as a diagnostic criterion, although a possible role in the pathology of diseases, for example through mRNA or protein production, cannot be excluded. The molecular mechanism, host-cell type and possible clinical significance of tissue persistence are yet to be elucidated.

Abstract
BACKGROUND The presence of viral genome in the myocardium of patients with dilated cardiomyopathy (DCM) has been suggested as causative for the underlying cardiac disease. Nevertheless, the results of present studies are conflicting regarding the natural course of heart diseases associated with detection of viral genome. This study was undertaken to determine if the detection of viral genome in the myocardium of patients with DCM is of functional and prognostic relevance under modern treatment strategies of heart insufficiency. METHODS In 197 patients with DCM, left ventricular endomyocardial biopsies were performed. Analysis for genome of adenovirus, enterovirus (EV), and parvovirus B19 as well as enteroviral replication and immunohistology was performed. RESULTS The increase in ejection fraction (EF) was 14.5 +/- 12.4% in the EV-positive group compared with 11.1 +/- 14.2 in the EV-negative group (P = not significant [NS]) after a mean follow-up (FU) of 19.5 and 17.6 months. The increase in EF in the virus-positive group (positive for EV, adenovirus, or parvovirus B19) was 15.3 +/- 13.3% compared with 12.3 +/- 11.9% in the virus-negative group (P = NS) after a mean FU of 17.6 and 11.5 months. There was no significant difference in the change of EF between the EV-positive and virus-negative groups. Detection of enteroviral RNA replication (detection of EV minus-strand RNA) did not result in a deterioration of left ventricular function compared with the virus-negative group (P = NS) after mean FU of 11.2 and 12.0 months. The transplantation-free survival of the patients was not influenced by detection of viral genome. CONCLUSIONS Our results favor the view that the presence of viral genome in the myocardium of patients with DCM is of no functional and prognostic relevance.

Abstract
Cardiac troponin I is released from myocytes in both reversible and irreversible myocardial injury. The changes in myocyte membrane permeability resulting from the injury could be enough for the release of cardiac troponins from the free cytosolic pool of myocytes without structural damage. We report a case of parvovirus B19 myocarditis in a 26-year-old male who developed regional wall motion abnormalities and severe left ventricular systolic dysfunction with elevated serum levels of cardiac troponin I (peak=11.7 ng/ml). Diagnosis of parvovirus myocarditis was confirmed by presence of high titers of parvovirus B19 IgG and identification of parvovirus B19 DNA by polymerase chain reaction. Within a few days of supportive treatment, the regional wall motion abnormalities resolved, the cardiac function recovered, and the elevation in serum cardiac troponin I subsided. This case further denotes the possibility of release of cardiac troponin I in non-ischemic, reversible myocardial injury.

Abstract
BACKGROUND The etiology of left ventricular (LV) isolated diastolic dysfunction often remains unclear. In the present study, we report a strong association between parvovirus B19 (PVB19) genomes and isolated LV diastolic dysfunction. METHODS AND RESULTS In 70 patients (mean+/-SD age, 43+/-11 years) admitted with exertional dyspnea and/or reduced exercise tolerance despite preserved LV systolic contractility (ejection fraction=68%), isolated diastolic dysfunction was clinically suspected. Patients with classic risk factors for diastolic dysfunction such as hypertension, coronary heart disease, diabetes mellitus, or pulmonary disease had been excluded. Diastolic function was assessed by echocardiography and LV and RV catheterization. Endomyocardial biopsies (EMBs) were analyzed for the presence of storage or infiltrative diseases or myocarditis, including molecular screening for cardiotropic virus genomes. In a substudy of 24 patients who reported atypical angina, coronary endothelial function was additionally investigated with a coronary Doppler flow-wire technique. In 37 of 70 patients (53%), isolated diastolic dysfunction was confirmed as the cause of their clinical symptoms. No evidence for cardiac storage or infiltrative diseases was found in these cases, but in 35 of 37 of these patients (95%), cardiotropic virus genomes were detected in EMBs (P<0.001). PVB19 was the most frequent pathogen in 31 of 37 patients (84%). In a subgroup of 10 patients with diastolic dysfunction and coexisting endothelial dysfunction, all 10 (100%) were PVB19 positive. CONCLUSIONS PVB19 genomes were predominant in patients with unexplained, isolated diastolic dysfunction. A strong association with the incidence of endothelial dysfunction was obvious, consistent with the hypothesis that PVB19-induced endothelial dysfunction may be a possible pathomechanism underlying diastolic dysfunction.

Abstract
Aside from enteroviruses and other viruses, e.g., adenoviruses, which are known to be associated with idiopathic dilated cardiomyopathy (IDC), a cardiac tropism is also attributed to parvovirus B19 (PVB19). The purpose of the present study was to determine the prevalence of enterovirus, adenovirus and PVB19 genomes in the myocardium of adult patients with IDC and to analyze the significance of PVB19 with regard to the course of the disease, as compared to the other cardiotropic viruses. In 52 adult patients with IDC and 10 control patients with normal left ventricular ejection fraction (> or =55%) undergoing coronary artery bypass surgery, myocardial tissue samples were investigated for enteroviral RNA using polymerase chain reaction (PCR) and Southern blot hybridization of the PCR product. Specific nested PCR was used to assess the prevalence of adenovirus and PVB19 DNA, in addition to sequencing of the latter. The clinical and echocardiographic course of the disease was followed for a mean (+/- SD) period of 21.1+/-9.5 months. Fourteen of the 52 patients (27%) were enterovirus-positive, 2/52 (4%) patients were adenovirus-positive, 14/52 (27%) patients were PVB19-positive, 8/52 (15%) patients were enterovirus plus PVB19-positive, and in 14/52 (27%) patients no viral genomes were found. Six patients died during the follow-up period, without any significant difference between the patient groups: 1/14 (7%) in the enterovirus-positive, 0/2 (0%) in the adenovirus-positive, 2/14 (14%) in the PVB19-positive, 1/8 (12.5%) in the enterovirus plus PVB19-positive, and 2/14 (14%) in the virus-negative group. PVB19 genome was found in 4 of the 10 (40%) control patients, but no enterovirus or adenovirus genomes were detected in these patients. In conclusion, in the myocardium of patients with IDC, PVB19 is detectable as frequently as enteroviral genome. PVB19-positive patients with IDC have a rather favorable prognosis and do not differ significantly from the other virus-positive or virus-negative patient groups with respect to survival. Finally, the pathogenetic and prognostic significance of PVB19 in IDC still remains unclear.

Abstract
BACKGROUND Enteroviruses (EVs) and adenoviruses (ADVs) have been considered common causes of myocarditis and dilated cardiomyopathy. In the present study, we report on the association of parvovirus B19 (PVB19) genomes in the clinical setting of acute myocarditis. METHODS AND RESULTS This study included 24 consecutive patients admitted to our hospital within 24 hours after onset of chest pain. Acute myocardial infarction had been excluded in all patients by coronary angiography. Endomyocardial biopsies were analyzed by nested polymerase chain reaction/reverse transcriptase-polymerase chain reaction for EV, ADV, PVB19, human cytomegalovirus, Epstein-Barr virus, Chlamydia pneumoniae, influenza virus A and B, and Borrelia burgdorferi genomes, respectively, followed by direct sequencing of the amplification products. All patients presented with acute onset of angina pectoris and ST-segment elevations or T-wave inversion mimicking acute myocardial infarction. Mean baseline peak creatinine kinase and creatine kinase-isoenzyme fraction were 342+/-241 U/L and 32+/-20 U/L, respectively. Mean troponin T was increased to 7.5+/-15.0 ng/mL and C-reactive protein to 91+/-98 mg/mL. Eighteen patients had global or regional wall motion abnormalities (ejection fraction 62.5+/-15.5%). Histological analysis excluded the presence of active or borderline myocarditis in all but one patient. PVB19, EV, and ADV genomes were detected in the myocardium of 12, 3, and 2 patients, respectively (71%). Follow-up biopsies of virus-positive patients (11 of 17) demonstrated persistence of PVB19 genomes in 6 of 6 patients, EV genomes in 2 of 3 patients, and ADV genomes in 1 of 2 patients, respectively. CONCLUSIONS Virus genomes can be demonstrated in 71% of patients with normal coronary anatomy, clinically mimicking acute myocardial infarction. In addition to EVs and ADVs, PVB19 was the most frequent pathogen.

Abstract
Since its discovery, human parvovirus B19 has been linked with a broad spectrum of clinical syndromes. An aetiological role for the virus has been confirmed in erythema infectiosum, transient aplastic crisis, persistent infection manifesting as pure red cell aplasia in immunocompromised persons, non-immune hydrops fetalis and arthritis. Less commonly recognised, but receiving increasing attention recently, are the neurological manifestations, a variety of which have been described in patients with either clinically diagnosed or laboratory confirmed B19 infection. The purpose of this review is to summarise present knowledge of B19, its known and potential pathogenic mechanisms and its association with human diseases, particularly those with neurological manifestations. The outcome of the review supports an aetiological role of the virus in neurological disease. However, the pathogenesis remains unknown and elucidating this is a priority.

Abstract
Parvovirus B19 (B19) was discovered in 1974 and is the only member of the family Parvoviridae known to be pathogenic in humans. Despite the inability to propagate the virus in cell cultures, much has been learned about the pathophysiology of this virus, including the identification of the cellular receptor (P antigen), and the control of the virus by the immune system. B19 is widespread, and manifestations of infection vary with the immunologic and hematologic status of the host. In healthy immunocompetent individuals B19 is the cause of erythema infectiosum and, particularly in adults, acute symmetric polyarthropathy. Due to the tropism of B19 to erythroid progenitor cells, infection in individuals with an underlying hemolytic disorder causes transient aplastic crisis. In the immunocompromised host persistent B19 infection is manifested as pure red cell aplasia and chronic anemia. Likewise, the immature immune response of the fetus may render it susceptible to infection, leading to fetal death in utero, hydrops fetalis, or development of congenital anemia. B19 has also been suggested as the causative agent in a variety of clinical syndromes, but given the common nature, causality is often difficult to infer. Diagnosis is primarily based on detection of specific antibodies by enzyme-linked immunosorbent assay or detection of viral DNA by dot blot hybridization or PCR. Treatment of persistent infection with immunoglobulin reduces the viral load and results in a marked resolution of anemia. Vaccine phase I trials show promising results.

Abstract
This review focuses on the role that human parvovirus B19 nonstructural (NS1) protein as a transactivator of the proinflammatory cytokine, interleukin-6 (IL-6), might play in triggering the multiparametric inflammatory outcomes of B19 infection. Parvovirus B19 is a ubiquitous virus, and it is often expressed during conditions of immunodepression including that induced by long-term chemotherapy, viral infection (HIV, HTLV-1), or genetic immunodeficiency disorders. Through NS1 expression, B19 may contribute to the immune dysregulation associated with these disorders, or serve as a cofactor in enhancing retroviral replication. Hence, NS1 transactivation of proinflammatory cytokine promoters such as IL-6 may be pivotal in triggering the various inflammatory and autoimmune disorders that have been linked to parvovirus B19 infections.

Abstract
In immunocompromised patients, clinical manifestations of human parvovirus B19 (PVB19) infection are mostly reported as acute or chronic hematological disorders. Recently, PVB19 infection has been associated with nonhematological symptoms. Four years after lung transplantation, a 9-year-old girl developed a severe anemia with reticulocytopenia requiring blood transfusion. PVB19 DNA was found by polymerase chain reaction in blood. Blood marrow aspiration revealed typical features of PVB19 infection. She was successfully treated with high dose of i.v. Ig. Then, she exhibited recurrent nonregenerative anemia requiring another course of i.v. Ig. PVB19 DNA has been persisted in blood with no specific immune response. At the same time, she suffered from several lung infection syndromes with no microorganism found except PVB19 DNA. Recurrent mild renal dysfunction was noticed with no other explanation than PVB19 infection. This report indicates that pediatric transplanted patients are at risk of chronic PVB19 infection, which can be associated with lung and/or renal disorders.

Abstract
We describe a 65-year-old female who presented with arthritis involving the small joints of her hand, wrists, and knee, fever, rash, and leukocytosis. During the course of her illness, she developed elevated transaminases, myositis, bilateral pleural effusions, a large pericardial effusion compressing the right atrium, and cardiomyopathy with impaired left ventricular function. The patient had evidence of acute parvovirus B19 infection by serology, although parvovirus specific DNA sequences from peripheral white blood cells were negative by polymerase chain reaction. This illness raised concern about possible collagen vascular disease. Low titers of antinuclear antibodies were present transiently, and other autoantibodies were undetected. Treatment with intravenous immunoglobulin resulted in dramatic resolution of her disease manifestations. Pericardial effusion and cardiomyopathy may be rare sequelae of parvovirus B19 infection. The apparent improvement with intravenous immunoglobulin could have been related to clearance of infection or down regulation of host immune response.

Abstract
Infections commonly complicate cardiac transplantation, and the clinical presentation of post-transplantation infection is usually readily distinguishable from that of rejection. Infection of the allograft may mimic rejection, however, and endomyocardial biopsies are required to distinguish these two entities. Cytomegalovirus is the most common cause of post-transplant cardiac infection. Although there are noninvasive studies that may suggest a diagnosis of cytomegalovirus infection, the noninvasive diagnosis of infection-related myocarditis remains challenging.

Abstract
Fifth (erythema infectiosum) and sixth (roseola infantum) diseases are common rash illnesses of childhood that have long been recognized in clinical medicine. The discovery of the viruses that cause these illnesses has revealed relationships with other syndromes. Primary infection with the agent of erythema infectiosum, human parvovirus B19, is associated with transient aplastic crisis in hemolytic anemia, arthropathy in adults, chronic anemia in immunocompromised patients, and nonimmune fetal hydrops in pregnant women. The only documented illness associated with primary infection with human herpesvirus 6 is roseola or exanthema subitum in young children. However, reactivated infections in adults and immunocompromised patients may be associated with serious illness such as encephalitis/encephalopathy, and bone marrow suppression leading to transplant failure or graft-versus-host disease. Diagnostic studies for both viruses have been limited, although reliable serologic tests for human parvovirus B19 have recently become available. Diagnosis of human herpesvirus 6 remains problematic, because current tests cannot differentiate primary from reactivated disease. This is more of an issue for the putative relationship of these viruses to more chronic conditions, such as rheumatologic disease for human parvovirus B19 and multiple sclerosis for human herpesvirus 6. The relationship between the viruses and these conditions remains controversial, and better diagnostic tests and further information on viral pathogenesis for both viruses are required in order to make a reliable judgment in this regard.

Abstract
Infection with parvovirus B19 is common in children and typically causes mild illness. We report here the case of a 5-year-old girl who died suddenly, 2 weeks after the clinical diagnosis of a parvoviral infection (erythema infectiosum). Microscopic examination of the heart showed severe myocarditis with extensive T-cell and macrophage infiltration. Cultures, serology, and molecular analyses of serum for enteroviridae, adenovirus, influenza, varicella zoster, cytomegalovirus, and herpes simplex viruses were negative. Quantitative polymerase chain reaction (PCR) analysis for parvovirus B19 in peripheral blood, however, showed active infection (91,000 genomes/mL serum; 2.4 genomes/mononuclear cell). Despite the presence of myocarditis, immunostaining for parvoviral surface antigens was negative in the heart. Quantitative PCR analysis of paraffin sections showed that myocardial parvoviral content was significantly less than that of the normal appearing kidney and within the range predicted simply by tissue blood content. Thus, parvovirus B19 infection can be complicated by fatal myocarditis. Because the virus does not appear to have infected the heart, per se, we speculate that myocarditis arose from immunological cross-reaction to epitopes shared between the virus and the myocardium.

Abstract
Human parvovirus B19 infection is occasionally associated with acute lymphocytic myocarditis (ALM). Three infants with B19 virus-associated ALM were followed up clinically, histologically, and immunovirologically. Each infant had B19 virus DNA in the blood or B19 virus-specific IgM antibodies. Two infants with postnatal infection recovered after immunosuppressive therapy. The third infant with possible prenatal infection developed chronic persistent myocarditis associated with persistent B19 virus DNA in the blood. All 3 infants had increased levels of interferon-gamma, tumor necrosis factor-alpha, and interleukins -6 and -8. Four newborns with congenital B19 virus infection and 4 infants and children who had postnatally acquired B19 virus infection without myocarditis all had normal levels of these cytokines. These observations suggest that B19 virus infection in infancy causes ALM in some infants and children.
