The N-terminal 5-68 amino acids domain of the minor capsid protein VP1 of human parvovirus B19 enters human erythroid progenitors and inhibits B19 infection.

J Virol 2021 May 5. Epub 2021 May 5.

Department of Microbiology, Molecular Genetics and Immunology, University of Kansas Medical Center, Kansas City, Kansas, USA

Parvovirus B19 (B19V) infection causes diseases in humans ranging from the mild to severe hematological disorders. The unique region of the minor structural protein VP1 (VP1u) of 227 amino acids harbors strong neutralizing epitopes which elicit dominant immune responses in patients. Recent studies have shown that the VP1u selectively binds to and enters B19V permissive cells through an unknown cellular proteinaceous receptor. Read More

Tale of two viruses: parvovirus B19 and HIV.

BMJ Case Rep 2021 Apr 20;14(4). Epub 2021 Apr 20.

Department of Paediatric Infectious Diseases, Imperial College Healthcare NHS Trust, London, UK.

We present a HIV-infected patient who developed severe anaemia due to chronic parvovirus B19 infection and subsequently had an unplanned pregnancy. This is in the context of poor adherence to antiretroviral therapy and significant immunosuppression; there was a delay in diagnosis of chronic parvovirus infection due to attribution of anaemia to HIV. She received immunoglobulin therapy and effective antiretroviral therapy, with reduction in parvovirus load and improvement in anaemia. Read More

Prevalence and Phylogenetic Analysis of Parvovirus (B19V) among Blood Donors with Different Nationalities Residing in Qatar.

Viruses 2021 03 24;13(4). Epub 2021 Mar 24.

Biomedical Research Center, Member of QU Health, Qatar University, Doha, Qatar.

Human parvovirus (B19V) is the causative agent of erythema infectiosum in children and is linked to a wide range of clinical manifestations. Studies related to B19V prevalence in the Middle East and North Africa (MENA) region and other parts of Asia are very scarce. The objectives of this study were to estimate the seroprevalence (anti-B19V IgM and IgG), the viremia rate (B19V DNA), and the circulating genotypes of B19V among blood donors in Qatar. Read More

Comprehensive surveillance data suggest a prominent role of parvovirus B19 infection in Belarus and the presence of a third subtype within subgenotype 1a.

Sci Rep 2021 Jan 13;11(1):1225. Epub 2021 Jan 13.

Department of Infection and Immunity, Luxembourg Institute of Health, Esch-sur-Alzette, Luxembourg.

Human parvovirus B19 (B19V) infection is not notifiable in Belarus and its most common clinical presentation erythema infectiosum (EI) is often difficult to distinguish from other exanthematous diseases. The objective of this study was to provide comprehensive data about EI epidemiology in Belarus based on the serological and molecular investigation of samples from measles and rubella discarded cases collected between 2005 and 2019. Overall, 4919 sera were investigated for IgM antibodies against B19V and the positive cases were analysed according to year, season and age. Read More

A literature review on the parvovirus B19 infection in sickle cell anemia and β-thalassemia patients.

Trop Med Health 2020 Dec 2;48(1):96. Epub 2020 Dec 2.

Infectious and Tropical Diseases Research Center, Hormozgan Health Institute, Hormozgan University of Medical Sciences, Bandar Abbas, Iran.

Background: Parvovirus B19 is the causative agent for erythema infectiosum, and also as a potentially life-threatening infectious agent, it is mainly presented in high erythrocyte turnover patients. Sickle cell disease (SCD) is an inherited monogenic hematological disorder resulting from the mutations in the hemoglobin β-chain gene. Thalassemia is a hereditary hematological syndrome that happens in consequence of deficiencies in the production of one or more globin chains. Read More

Myocarditis and inflammatory cardiomyopathy: current evidence and future directions.

Nat Rev Cardiol 2021 03 12;18(3):169-193. Epub 2020 Oct 12.

Berlin Institute of Health Center for Regenerative Therapies (BCRT), Charité - University Medicine Berlin, Campus Virchow Clinic, Berlin, Germany.

Inflammatory cardiomyopathy, characterized by inflammatory cell infiltration into the myocardium and a high risk of deteriorating cardiac function, has a heterogeneous aetiology. Inflammatory cardiomyopathy is predominantly mediated by viral infection, but can also be induced by bacterial, protozoal or fungal infections as well as a wide variety of toxic substances and drugs and systemic immune-mediated diseases. Despite extensive research, inflammatory cardiomyopathy complicated by left ventricular dysfunction, heart failure or arrhythmia is associated with a poor prognosis. Read More

Department of Perinatal Medicine, Mercy Hospital for Women, Melbourne, Victoria, Australia.

Parvovirus B19 (B19V) infection is well known for its mild, self-limiting clinical presentations in children, such as erythema infectiosum. Approximately 40% of women of childbearing age are susceptible to B19V infection. While maternal B19V infection usually has a good prognosis, B19V can cause severe fetal anaemia and pregnancy loss due to its ability to suppress erythroid progenitor cells. Read More

Paediatrics, Al Jalila Children's Speciality Hospital, Dubai, ARE.

Most of the parvovirus infections in humans are benign. Clinical manifestations of parvovirus B19 infections in children vary from erythema infectiosum in healthy children to aplastic crisis in patients with hematological disorders (such as sickle cell disease) and immunocompromised patients. Parvovirus B19 infects the erythroid progenitor cell in the bone marrow and causes transient erythroblastopenia. Read More

College of Medical, Hubei University of Arts and Science, Xiangyang 441053, Hubei, China.

Human parvovirus B19 (B19 virus) is one of the two parvoviruses that cause human diseases. As an important pathogen to humans, it causes infectious erythema in children, acute aplastic anemia, fetal edema and death. In this review, we focus on the recent advances in the molecular virology of B19V, such as viral genotypes, viral receptor, genomic features and viral replication, viral transcription and post-transcription regulation, viral nonstructural and structural protein features and functions, viral diagnosis and antiviral agents, to provide reference for further study of B19 pathogenesis mechanisms, treatment and diagnostic strategies.

Sudden death of a young adult with coronary artery vasculitis, coronary aneurysms, parvovirus B19 infection and Kawasaki disease.

Forensic Sci Med Pathol 2020 09 3;16(3):498-503. Epub 2020 Jun 3.

Medical Faculty, Institute of Legal Medicine, University of Cologne, Melatengürtel 60-62, 50823, Cologne, Germany.

We present a case of a 20-year-old man who suffered from Kawasaki disease (KD) associated with a florid parvovirus infection, and who died suddenly from thrombotic occlusion of the coronary arteries. The autopsy revealed several aneurysms of the coronary arteries, a chronic vasculitis and a myofibroblast proliferation leading to focal luminal narrowing. The inflammatory response as well as the detection of the viral particles by PCR in blood and in the lesional tissue demonstrated a possible cause by Parvovirus infection. Read More

Pure Red Cell Aplasia and Antibody-Mediated Rejection: Double Trouble in 1 Kidney Transplant Recipient Solved by Intravenous Immunoglobulin Infusion: A Case Report.

Transplant Proc 2020 Oct 8;52(8):2530-2532. Epub 2020 Apr 8.

Department of Internal Medicine, Clinic of Nephrology, Hypertension and Internal Diseases of the University of Warmia and Mazury in Olsztyn, Olsztyn, Poland.

Acquired pure red cell aplasia (PRCA) is characterized by severe normocytic (rarely macrocytic) and normochromic anemia, a low reticulocytes count in peripheral blood, and near absence of erythroid precursors in the bone marrow, with a normal level of erythropoietin. We describe a case of the kidney transplant recipient, diagnosed with PRCA induced with parvovirus B19 infection. Our case demonstrates that although this complication is rare, it should be considered in a differential diagnosis of anemia diagnostics in immunocompromised patients. Read More

J Pediatr Hematol Oncol 2020 05;42(4):e213-e218

Department of Hepatitis and AIDS, Pasteur Institute of Iran, Tehran, Iran.

Objective: Blood-derived products from patient with hemophilia treated by factor VIII concentrates are potential sources of transfusion-transmitted infections, including human immunodeficiency virus, hepatitis, human pegivirus-1 (HPgV-1), B19 virus, and also human hepegivirus-1 (HHpgV-1). In the current study, we investigated the impact of blood transfusion on the prevalence of HHpgV-1, HPgV-1, and B19 virus in plasma of Iranian patient with hemophilia after direct-acting antiviral treatment of hepatitis C virus (HCV) infections for the first time.
