There are striking similarities between human parvovirus B19 (HPV-B19) infection and systemic lupus erythematosus (SLE): both may present with malar rash, fever, arthropathy, myalgia, cytopenia, hypocomplementemia, anti-DNA, and antinuclear antibodies (ANA). Therefore, it is difficult at times to differentiate HPV-B19 infection from SLE presentation or exacerbation. We report 4 cases of HPV-B19...

Recent reports suggested that parvovirus B19 (B19) might persist in immunocompetent individuals such as blood donors, but only cross-sectional data were available. Serial samples from a cohort of multitransfused patients with hemoglobinopathies and a cross-sectional population of pregnant women were tested for B19 markers. Of 76 red cell recipients, 6 (8%) had persistent viral DNA for 1 to 3 or...

This study was undertaken to provide first-time estimates for the seroprevalence of parvovirus B19 infection among daycare educators in Montréal, Canada, and to identify factors associated with seropositivity. A cross-sectional design was used. Directors and educators from 81 daycare centres (DCCs) were surveyed about DCC and personal characteristics respectively, and serum samples from 477 fem...

human parvovirus b19, the causative agent of fifth disease in childhood, is non-enveloped dna virus and resistant to many physicochemical agents. b19 is a potential risk to hemophiliac patients receiving blood products. to determine the prevalence of the corresponding antibody in patients with hemophilia a or b or von will brand’s disease (vwbd), we tested 180 hemophilia patients aged 1-45 year...

Parvovirus B19 has a marked tropism for erythroid progenitor cells. This may lead to chronic anemia in predisposed individuals. The purpose of the study was to investigate the frequency of parvovirus B19 infections in patients with diagnosis of haematological disorders. In order to determine the diagnostic use of different markers of parvovirus B19 infection, serum specimens obtained from 79 pa...

Human parvovirus B19 infects predominantly erythroid precursor cells, leading to inhibition of erythropoiesis. This erythroid cell damage is mediated by the viral nonstructural protein 1 (NS1) through an apoptotic mechanism. We previously demonstrated that B19 virus infection induces G(2) arrest in erythroid UT7/Epo-S1 cells; however, the role of NS1 in regulating cell cycle arrest is unknown. ...

Clinical respiratory illness was compared in five homozygous chicken lines, originating from homozygous B2, B8, B12 and B19, and heterozygous B2/B12 birds after infection with either of two strains of the infectious bronchitis virus (IBV). All chickens used in these studies originated from White Leghorn and Ancona linages. IBV Gray strain infection of MHC homozygous B12 and B19 haplotype chicks...

A clinical association between idiopathic liver disease and parvovirus B19 infection has been observed. Fulminant liver failure, not associated with other liver-tropic viruses, has been attributed to B19 in numerous reports, suggesting a possible role for B19 components in the extensive hepatocyte cytotoxicity observed in this condition. A recent report by Abe and colleagues (Int J Med Sci. 200...

Clinical, biochemical and molecular evidence for the sickle cell anemia (SCA) crisis in Nigerian patients arising from parvovirus b19 infection remains inadequate. This study determined the prevalence and correlates of anti-parvovirus b19 antibodies in a population of SCA patients and non-SCA healthy controls in Lagos, Nigeria. In this prospective cross-sectional study, we enrolled 73 confirmed...
