Prevalence of Parvovirus B19 and Human Bocavirus DNA in the Heart of Patients with no Evidence of Dilated Cardiomyopathy or MyocarditisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions. Our data suggest that B19V but not HBoV demonstrates a lifelong persistence in the heart. The detection of B19V DNA in heart tissue showed no correlation with clinical symptoms. We strongly recommend that serological testing become a standardized procedure for future studies, to obtain representative data concerning the prevalence of B19V in the heart.

Intrahepatic long-term persistence of parvovirus B19 and its role in chronic viral hepatitisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study aimed to investigate the impact of B19V infection in European patients with viral hepatitis. B19V DNA was detected in 1/91 and 0/50 serum samples from patients with chronic hepatitis C and B, respectively. In contrast, B19V DNA was amplified frequently from explanted end-stage liver tissues (37/50, 74%) and from routine biopsy samples (14/32, 44%) (P < 0.05). However, there was no significant difference in B19V copy number per cell between these two groups. B19V-specific CD4+ T-cell responses to two dominant MHC-class-restricted epitopes were detected in a similar frequency in healthy anti-B19V-positive individu...

A linked donor-recipient study to evaluate parvovirus B19 transmission by blood component transfusionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Parvovirus B19V infection can be a serious infection for hematology patients with underlying hemolysis or compromised erythropoiesis syndromes. Although case reports of B19V transmission by blood component transfusion (as contrasted to manufactured plasma derivatives) are rare, no studies have systematically determined a rate of transmission to recipients transfused with B19V DNA–positive components. We used a linked donor and recipient repository and a sensitive, quantitative B19V DNA polymerase chain reaction (PCR) assay to assess such transmission in B19V-susceptible (ie, anti-B19V immunoglobulin G [IgG] negative)...

Discussion Rashes, particularly ones caused by viruses, are common presenting problems. In his first edition of Pediatrics, Dr. Rotch spent 72 pages describing infectious exanthemata. The cause of the exanthemata was unknown at the time, and thankfully many of those that he wrote of have been eradicated (smallpox), have effective vaccines to prevent (measles, rubella, varicella) or effective antibiotics for treatment (streptococcus). Dr. Rotch ends his extensive treatise with a table describing “the chief points of differential diagnosis in the exanthemata.” This is what was state-of-the-art in 1896 with his s...

Rashes and Fever in Children: Sorting Out the Potentially Dangerous, Part 3Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Children who present with rash and fever can be divided into 3 groups: those with features of serious illness who require immediate intervention, those with clearly recognizable viral syndromes, and those with early or undifferentiated rash. The morphology of lesions among children with symptoms of serious illness offers clues to the underlying cause. Fever accompanied by pharyngitis and a “sandpaper” rash that begins around the neck suggests scarlet fever. In most children with fever and rash who have clearly recognizable viral illnesses, such as measles or erythema infectiosum, diagnosis is clinical and therapy inclu...

Phylogenetic analysis of a near-full-length sequence of an erythrovirus genotype 3 strain isolated in BrazilEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Human parvovirus B19 is the only member of the genus Erythrovirus that causes human disease. Recent findings of several strains with considerable sequence divergence from B19 have suggested a new classification for parvovirus genotypes as 1 (B19), 2 (A-6 and LaLi) and 3 (V9). In their overall DNA sequence, the three genotypes differ by ~10%. Here, we report the isolation of a genotype-3-related strain named BR543 during a prospective study conducted in Sao Paulo, Brazil. Analysis of the nearly full-length genome sequence of BR543 indicates that this B19 variant sequence clusters with Gh2768, a strai...

Conclusions: Parvovirus B19 may be detected at low frequency in BAL specimens from patients with different pathological backgrounds. This finding could be due to chronic infection with virus persistence in the lower respiratory tract, also in the absence of symptoms unequivocally attributable to B19.

High Rate of Severe Fetal Outcomes Associated with Maternal Parvovirus B19 Infection in PregnancyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions. These findings suggest that parvovirus B19 infection in pregnancy follows seasonal and annual trend variation, may produce a lower frequency of maternal symptoms and a higher fetal loss rate than previously reported. Synopsis. Maternal parvovirus B19 infection follows seasonal and annual variation is often asymptomatic and may have higher fetal loss rates than previously reported. Continued surveillance is warranted. (Source: Infectious Diseases in Obstetrics and Gynecology)

Melkersson–Rosenthal syndrome associated with parvovirus b19 viraemia and haemophagocytic lymphohistiocytosisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We describe a 23-year-old patient who presented acutely with haemophagocytic lymphohistiocytosis (HL) and Melkersson[ndash]Rosenthal syndrome (MRS). MRS and HL are two unusual and complex clinical patterns that may present acutely and to our knowledge, an association between them has never been reported. The clinical investigations in this patient led to identification of parvovirus B19 (PB19) viraemia by PCR. Parvovirus infection has been reported as a cause of virus-associated HL, but the presence of PB19 has never been sought or reported as a possible trigger for MRS. This observation suggests a possible association bet...

Viral causes of human myocarditis.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The diagnosis of acute myocarditis is complex and challenging. The use of the Dallas criteria in the diagnosis of myocarditis is associated with poor sensitivity and specificity because of the sampling error related to the often focal distribution of the specific histological lesions in cardiac tissue and the variability in pathological interpretation. To improve histological diagnosis, additional virological evaluation of cardiac tissues is required, with immunohistochemical and polymerase chain reaction (PCR) techniques allowing identification and quantification of viral infection markers. The diagnostic gold standar...

No detection of human bocavirus in amniotic fluid samples from fetuses with hydrops or isolated effusionsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: We suggest that HBoV is not a common cause of fetal hydrops, anemia or isolated effusions. This has to be confirmed by further studies of proven gestational HBoV infection. (Source: Journal of Clinical Virology)

Antibody-mediated opsonization of red blood cells in parvovirus B19 infection.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In this study, we report that in early, acute or persistent infection, B19 viremia is mostly associated with RBCs. The capacity of different patients' plasma or IgG to opsonize RBCs collected from patients with early B19 infection, was investigated. The highest opsonization activity was observed with plasma or IgG fractions from patients with past B19 infection. In contrast, IgG samples from patients with acute or persistent infection showed no or little opsonization activity. The depletion of antibodies specific to B19 VP1, but not VP2, from IgG samples, resulted in a significant suppression of opsonization. Furthermore, ...

Acute arthropathy in patients with rash diseases: a comparative studyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The aim of this study was to assess the association of acute arthropathy and selected clinical features in patients with acute rash diseases. Serum samples from 1,554 patients were tested for anti-measles, dengue, human parvovirus B19, and rubella virus IgM using enzyme immunoassay. Sera from children, in whom these infections were excluded, were studied for anti-human herpesvirus type 6 IgG antibodies using an indirect immunofluorescence test. Joint complaints occurred in 31.2% of the 862 patients with an etiologic diagnosis and were more frequently seen in adults than in children (OR 8.5). Among t...

Simultaneous acute splenic sequestration and transient aplastic crisis in children with sickle cell diseaseEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Acute splenic sequestration crisis (ASSC) is a hematological emergency in young children with sickle cell disease (SCD), characterized by worsening anemia and splenomegaly, usually with reticulocytosis and thrombocytopenia. Transient aplastic crisis (TAC) due to parvovirus B19 infection occurs in older children with SCD, and typically manifests as worsening anemia with reticulocytopenia and no splenomegaly. Five older children with SCD (4 HbSC, 1 HbSS on hydroxyurea) developed ASSC concurrent with TAC and had a severe clinical course. Our cases suggest that older children with SCD and acute parvovirus infection should be m...
