We report on a seventeen-year-old boy with acute pleuro-pericarditis human parvovirus B19 (PVB19) infection. He presented chest pain, fever and shortness of breath. On physical examination, he had orthopnea, increased temperature (38,4 °C), tachycardia hepatomegaly. Echocardiography showed pericardial effusion 12 mm. Thoracic ultrasound revealed left pleural 10 Serum anti-Parvovirus 19 IgM Parv...
Human parvovirus B19 infection was studied in 60 thalassemic patients in Thailand. Seroprevalence, persistence of parvovirus B19 and their genotypes were identified in blood samples. Prevalence of anti-parvovirus B19 IgG and DNA found in thalassemic patients were 38% and 13%, respectively. Anti-parvovirus B19 IgM could be detected in 4% of these positive anti-parvovirus B19 IgG patients. The se...
background: infection with parvovirus b19 may cause fetal losses including spontaneous abortion, intrauterine fetal death and non-immune hydropsfetalis. the aim of this study is to determine the frequency of parvovirus b19 in formalin fixed placental tissues in lost fetuses using real-time pcr method. methods : in this cross-sectional study, 100 formalin fixed placental tissues with unknown c...
: Parvovirus is one of the uncommon causes anemia in a kidney transplant patient. We reported patient with parvovirus infection who developed severe three weeks after transplantation. Suspicion infections increased due to decrease erythrocyte level. The patient's became normal amount immunosuppressant and treatment intravenous immunoglobulin (IVIG). B19 should be considered all patients persist...
Molecular and serological assessment of parvovirus B19 infections among sickle cell anemia patients.
INTRODUCTION Parvovirus B19 is a cause of hemolysis and red blood cell aplasia in patients with sickle cell anemia. The present study aimed to assess parvovirus B19 infection among sickle cell anemia patients. METHODOLOGY All patients (n = 138) included in the study were sickle cell anemia patients. Blood donors were used as a control group. Assessment of parvovirus B19 antibodies and viral D...
BACKGROUND Parvovirus B19 infection during pregnancy can lead to nonimmune fetal hydrops, miscarriage, and intrauterine fetal death (IUFD). Some studies have suggested that parvovirus B19 infection may surprisingly often result in nonhydropic fetal death during the third trimester, in the absence of maternal serological evidence of acute infection. This study was conducted to investigate the pr...
There are few reports in the literature of hepatitis as a manifestation of parvovirus B19 infection. We describe a case of parvovirus B19-associated acute hepatitis diagnosed based on a positive serologic test (IgM) and molecular detection of parvovirus B19 DNA in a liver biopsy specimen. Parvovirus B19 infection should be considered in the differential diagnosis of patients presenting with acu...
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...
Parvovirus B19 is the etiologic agent of erythema infectiosum (fifth disease), a fever-rash illness occurring in childhood. We present a 10 month old child with high grade fever for 10 days, generalized tonic-clonic seizure, bilateral cervical lymphadenopathy, generalized maculopapular rash, hematemesis and malena. Bone marrow aspiration and liver biopsy were done. EBV serology and parvovirus P...
Porcine parvovirus 3 is a novel parvovirus that infects pigs. Here, we report two genome sequences of porcine parvovirus 3 strains GX1 and GX2, which are highly prevalent in Guangxi province. It will help in understanding the epidemiology and molecular characteristics of the porcine parvovirus 3.
