INTRODUCTION Human parvovirus B19 is found worldwide. It causes various infections, including fifth disease (erythema infectiosum) in small children, acute arthropathy in adults, transient aplastic crisis and chronic anemia in immunocompromised patients and even fetal infection, which may result in intrauterine fetal death or fetal hydrops. Many of these manifestations of B19 infection are caus...
We report on the case of a healthy young boy who developed a fulminant myocarditis due to acute coinfection with erythrovirus (parvovirus B19) and human herpesvirus 6 (HHV-6) in the absence of an antiviral immune response. We suggest that the HHV-6-induced immunosuppression enhanced dissemination of parvovirus B19, which led to fatal myocarditis.
Parvovirus B19 has been associated by some investigators with cases of severe hepatitis. The aim of the present study was to determine the presence of active parvovirus B19 infection among 129 Brazilian patients with non-A-E hepatitis. The patients were assayed for antibodies against parvovirus B19, IgM class, by ELISA. In IgM-positive cases, parvovirus B19 DNA was assayed by PCR in serum and l...
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...
A 59 year old woman presented with an influenza-like illness preceding signs and symptoms strongly suggestive of systemic lupus erythematosus (SLE), which progressed over several months. Owing to these influenza-like symptoms, a viral cause of her illness was sought. Human parvovirus B19 serology was positive and antibodies to DNA were detected by two different methods. This patient is believed...
Attempts were made to detect human parvovirus B19-DNA by in situ hybridisation and the polymerase chain reaction in placental and fetal tissues from a case of intrauterine fetal death. In the in situ hybridisation experiments radioactive and non-radioactive (labelled with 2-acetyl-aminofluorene, AAF) DNA probes were used. B19-DNA was detectable in paraffin wax embedded fetal tissue from the liv...
Background & Aims: Maternal infections with parvovirus B19 and cytomegalovirus (CMV) maybe associated with intrauterine fetal death. The aim of this study was to compare frequency of CMV & Parvovirus B19 Infections in intrauterine fetal death (IUFD) and normal pregnancy. Methods: In a case-control study in Afzalipour Hospital during 2006 placental biopsies were collected from 70 cases of IUFD a...
Papular-purpuric "gloves and socks" syndrome (PPGSS) is a novel, rare, self-limiting dermatosis caused by human parvovirus B19. It consists of pruritic edema and erythema of the hands and feet in a gloves-and-socks distribution, and it is associated with oral lesions and fever. We present a case of PPGSS in a 22-year-old Brazilian woman. Clinical and laboratory evaluation, including serological...
INTRODUCTION In most cases of stillbirth, the cause is still unknown. AIM The impact of parvovirus B19/erythrovirus infection and chromosomal abnormalities in stillborns and neonatal deaths. MATERIAL AND METHODS 57 consecutive cases, 23 second-trimester abortions (from gestational weeks 16 to 22), 27 intrauterine fetal deaths (from gestational week 22 onwards) and 7 early neonatal deaths we...
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...
