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...
background and objectives: trans-placental transmission of parvovirus b19 during pregnancy can causes adverse outcomes. regarding its importance in prenatal care, we decided to study prevalence of parvovirus b19 infection among pregnant woman in ardabil, iran. materials and methods: in a community based study with a cluster sampling, 350 pregnant women that attended in health care centers in ar...
Human parvovirus B19 is a very common viral infection especially in school-aged children. The infection during pregnancy can affect the fetus due to lack of mother's immunity. Although, there is still no evidence of fetal teratogenic effects with parvovirus B19, but non-immune fetal hydrops and abortion may be caused by vertical transmission of the virus during pregnancy. This study was aimed t...
BACKGROUND There is concern about the development of anemia-associated fetal hydrops associated with maternal parvovirus B19 infection. Parvovirus B19 infection occurs via the globoside (P antigen) receptor, the main glycolipid of erythroid cells, which induces apoptosis. Similar findings have been reported for the P antigen of globoside-containing placental trophoblast cells. CASE DESCRIPTIO...
Objectives: Facilitate risk assessment of vital complications in fetuses of pregnancies affected by acute parvovirus B19 infection. Design: Study of the natural course of maternal parvovirus B19 infection in four cases, from early pregnancy on. Setting: University medical center in the Netherlands. Population: Pregnant mothers attending obstetric services. Methods: Serial measurements of the ma...
Parvovirus B19 infection can cause severe effects in high-risk groups including pregnant women and immunocompromised individuals. Although serological detection of B19 infection is commonplace, minimal information is available on the absolute performance characteristics of various tests for the detection of B19 IgM. The performance of the first parvovirus B19 IgM enzyme immunoassay to be cleare...
BACKGROUND Maternofetal parvovirus B19 infection may result in fetal hydrops or abortion. Chronic infection has been associated with long term complications (polyarthritis, persistent aplastic anaemia, hepatitis). In pregnancy maternal immunosuppression caused by a TH2 dominant response to viral antigens has been observed. There is little information on long term reactivity to intrauterine infe...
OBJECTIVES (1) To review the effects of parvovirus B19 on the pregnant woman and fetus, and (2) to discuss the management of women who are exposed to, who are at risk of developing, or who develop parvovirus B19 infection in pregnancy. OUTCOMES Maternal outcomes of parvovirus B19 including erythema infectiosum, arthropathy, anemia, and myocarditis. Fetal outcomes including spontaneous abortio...
BACKGROUND The immune system has been implicated in the pathogenesis of certain clinical manifestations of parvovirus B19 infection, including rash and arthralgia. Cytokines feature in the pathogenesis of parvovirus B19 infection, so inherited variability in cytokine responses to B19 infection might have a bearing on the symptomatology of parvovirus B19 infection. AIMS To investigate the poss...
background: parvovirus b19 (b19) is the only member of the family parvoviridae associated with human infection. although there are some studies to estimate the immunity to parvovirus in various populations but there is no seroepidemiological survey from iran until now thus the age-specific immunity to human parvovirus infection was estimated. methods: a subset sample of 1500 study subjects...
