The nonstructural protein NS1 of human parvovirus B19 (B19) is known to exacerbate disease activity in systemic lupus erythematosus (SLE). However, no specific medicine for B19 infection is available. The roots of Gentiana macrophylla Pall. (GM), the traditional Chinese medicine "Qinjiao," have been used for centuries to treat rheumatic disease, including SLE. Herein, we aimed to investigate the effects of GM root extract (100 and 300 mg/kg body weight) on B19-NS1-exacerbated liver injury in NZB/W F1 mice; liver tissues were assessed by hematoxylin-eosin staining and immunoblotting...

Hemophagocytic lymphohistiocytosis (HLH) is a rare but life-threatening syndrome resulting from excessive immune activation. Secondarily, HLH is often associated with autoimmune disease, infection, and malignancy. The most common infectious trigger is Epstein-Barr virus (EBV) infection. HLH is rarely triggered by parvovirus B19. We discuss a case of a 62-year-old male who presented with multi-organ failure with presumed septic shock who eventually was diagnosed with HLH, with positive parvovirus B19 deoxyribonucleic acid (DNA) polymerase chain reaction (PCR)...

This study was conducted to provide information on the genetic diversity of human parvovirus B19 (B19V) circulating in the municipality of Niterói, Rio de Janeiro, Southeast Brazil during 1996-2006, a period with two distinct outbreaks of B19V infection: 1999-2000 and 2004-2005. A total of 27 sera from patients with erythema infectiosum and five sera from HIV-infected patients that tested positive for B19V DNA during the study period were analyzed. To genotype B19V strains, a semi-nested PCR for partial amplification of the capsid gene was performed and sequence analysis revealed that 31 sequences belonged to subgenotype 1a (G1a) of the main genotype 1 and one sequence was characterized as subgenotype 3b (G3b)...

Pure red cell aplasia (PRCA) is a syndrome defined by a normocytic normochromic anemia with severe reticulocytopenia and marked reduction or absence of erythroid precursors from the bone marrow. Diamond-Blackfan anemia is a congenital form of PRCA. Acquired PRCA may be either a primary disorder or secondary to some other disorder or agent. Primary acquired PRCA is an autoimmune disorder that is frequently antibody-mediated. Myelodysplastic syndromes may also present with the morphologic appearance of PRCA. Secondary acquired PRCA may be associated with collagen vascular/autoimmune disorders such as systemic lupus erythematosus; lymphoproliferative disorders such as chronic lymphocytic leukemia or large granular lymphocyte leukemia; infections, particularly B19 parvovirus; thymoma and other solid tumors; or a variety of other disorders, drugs, or toxic agents...

The present study aims to clarify the possible involvement of parvovirus B19 (B19V) infection in rheumatoid arthritis (RA) pathogenesis by investigating the presence of B19V infection markers (genomic sequences and virus-specific antibodies) in association with the level of cytokines and RA clinical activity and aggressiveness. A total of 118 RA patients and 49 age- and sex-matched healthy volunteers were enrolled in the study. Nested PCR was used to detect B19V sequences in whole blood and cell-free plasma DNA, ELISA to detect virus-specific antibodies and cytokine levels in plasma and recomLine dot blot assay for antibodies to separate B19V antigens...

Parvovirus B19 infection can cause a wide range of cutaneous manifestations, including papular-purpuric gloves-and-socks syndrome (PPGSS) and petechial bathing trunk eruption. We report a case of an immunocompetent woman with a primary parvovirus B19 infection presenting as concurrent PPGSS and petechial bathing trunk eruption. Parvovirus B19 seroconversion was confirmed several days after the onset of the clinical manifestations. The coexistence of these two cutaneous manifestations of primary parvovirus B19 infection has rarely been reported in the literature...

Parvovirus B19 infection is associated with a broad spectrum of clinical manifestations among which some are well known but others remain controversial. The role of this infection as a cause of acute hepatitis or exacerbation of chronic liver disease requires discussion regarding its significance in a strategy of prevention and treatment of patients with chronic hepatitis. Clinical importance of this infection in patients with chronic hepatitis B treated with pegylated interferon alpha 2a is still unclear but exactly in this population significant complications during treatment may arise...

Infections remain an issue of particular relevance in renal transplant patients, particularly viral infections. Human parvovirus B19 infection causes severe refractory anaemia, pancytopenia and thrombotic microangiopathy. Its presence is recognized by analysing blood polymerase chain reaction (PCR) and by the discovery of typical giant proerythroblasts in the bone marrow. We report the case of a 65 year-old man with a history of deceased donor renal transplant in September 2014. At 38 days after the transplant, the patient presented progressive anaemia that was resistant to erythropoiesis-stimulating agents...

Background. Parvovirus B19 (B19V) is a common finding in endomyocardial biopsy specimens from myocarditis and dilated cardiomyopathy patients. However, current understanding of how B19V is contributing to cardiac damage is rather limited due to the lack of appropriate mice models. In this work we demonstrate that immunization of BALB/c mice with the major immunogenic determinant of B19V located in the unique sequence of capsid protein VP1 (VP1u) is an adequate model to study B19V associated heart damage. Methods and Results...

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 (B19V) and human bocavirus 1 (HBoV1), members of the large Parvoviridae family, are human pathogens responsible for a variety of diseases. For B19V in particular, host features determine disease manifestations. These viruses are prevalent worldwide and are culturable in vitro, and serological and molecular assays are available but require careful interpretation of results. Additional human parvoviruses, including HBoV2 to -4, human parvovirus 4 (PARV4), and human bufavirus (BuV) are also reviewed...
