    History of parvovirus B19 infection is associated with silent cerebral infarcts.
    Pediatr Blood Cancer 2018 Jan 17;65(1). Epub 2017 Aug 17.
    Department of Medicine and Pediatrics, Vanderbilt-Meharry Sickle Cell Center of Excellence, Vanderbilt University Medical Center, Nashville, Tennessee.
    Background: The relationship between silent cerebral infarcts (SCIs) and history of parvovirus B19 (B19V) has not been systematically evaluated. As an ancillary study from the Silent Cerebral Infarct Trial (SIT) (NCT00072761), we tested the hypothesis that a history of B19V infection is associated with an increased prevalence of SCIs in children with sickle cell anemia.

    Procedure: We used a retrospective cross-sectional cohort study design; each participant underwent a brain magnetic resonance imaging (MRI) scan and medical record review for prior B19V infection (n = 958). Read More

    Immunohistochemical Demonstration of Parvovirus B19 Viral Protein 2 in Periflexural Exanthema in an Adult, Supporting Antibody-Dependent Enhancement as Means of Endothelial Uptake of the Virus.
    Am J Dermatopathol 2018 Feb;40(2):e19-e24
    Dermatology, and.
    Human parvovirus B19 (B19V) causes a number of skin exanthemas and has been related to both cutaneous and systemic diseases. Tropism of the virus for the rapidly proliferating erythroid progenitor cells in the bone marrow and fetal liver explains the pathogenesis of anemia and fetal hydrops. The cutaneous lesions of erythema infectiosum and other B19V-related exanthemas have been attributed to the deposition of immune complexes in the skin. Read More

    DNA Binding and Cleavage by the Human Parvovirus B19 NS1 Nuclease Domain.
    Biochemistry 2016 Nov 17;55(47):6577-6593. Epub 2016 Nov 17.
    Department of Chemistry and Biochemistry, University of Arizona , Tucson, Arizona 85721, United States.
    Infection with human parvovirus B19 (B19V) has been associated with a myriad of illnesses, including erythema infectiosum (Fifth disease), hydrops fetalis, arthropathy, hepatitis, and cardiomyopathy, and also possibly the triggering of any number of different autoimmune diseases. B19V NS1 is a multidomain protein that plays a critical role in viral replication, with predicted nuclease, helicase, and gene transactivation activities. Herein, we investigate the biochemical activities of the nuclease domain (residues 2-176) of B19V NS1 (NS1-nuc) in sequence-specific DNA binding of the viral origin of replication sequences, as well as those of promoter sequences, including the viral p6 and the human p21, TNFα, and IL-6 promoters previously identified in NS1-dependent transcriptional transactivation.

    Parvovirus B19 infection as a cause of acute myositis in an adult.
    Rev Bras Reumatol 2015 Mar-Apr;55(2):185-8. Epub 2014 Oct 5.
    Divisão de Hematologia, Departamento de Medicina Interna, Faculdade de Medicina, Universidade Bezmialem Vakif, Istambul, Turquia.
    Parvovirus B19 infection is often asymptomatic, but clinical expressions may include transient aplastic crisis, erythema infectiosum, non-immune hydrops fetalis, and chronic red cell aplasia. This virus has also been associated with rheumatoid arthritis and other autoimmune connective tissue diseases; however, we could not identify any acute adult myositis case developed after a Parvovirus B19 infection in the literature. For this reason, we would like to present a rare case of acute myositis developed after Parvovirus B19 infection. Read More
