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...

By definition, viral-associated GN indicates the direct pathogenic relationship between active viral replication and the development of acute GN. This definition is in sharp contrast to the semantic label and pathophysiologic foundation behind postinfectious GN that uniquely develops only during a period of resolved and absent active infection. The primary example of postinfectious GN are the glomerular lesions described after a pharyngeal or cutaneous streptococcal infection and do not represent the clinical or immunologic pattern seen with viral-associated GN...

Recent studies have demonstrated that, in common with other latent viruses, parvovirus B19 infection can be controlled by the host immune response but may persist in some places such as the bone marrow. Persistent B19 infection has been found in both immunocompetent and immunocompromised individuals, such as patients infected with human immunodeficiency virus (HIV). However, there is limited data regarding long-term B19 viremia in HIV patients. In this study, we investigated virological and hematological findings, and also the clinical outcome, of seven cases of HIV/B19 coinfection (confirmed by PCR) after one year...

The human parvovirus B19 (B19) usually causes a subclinical infection in immunocompetent individuals. Whereas immunocompromised individuals such as patients infected with HIV are at risk of persistent anemia due to B19 infection. Only few studies have been carried out on distribution and molecular epidemiology of B19 in Iran. We aimed to determine the frequency and genotype of B19 among Iranian patients infected with HIV. We conducted a survey on 99 HIV patients and 64 healthy controls. IgG and IgM antibodies against B19 were detected by ELISA and B19 DNA was assessed by nested PCR...

A case of primary Epstein-Barr virus (EBV) infection/parvovirus B19 reactivation fulfilling five of eight criteria for hemophagocytic lymphohistiocytosis (HLH) is presented. Despite two coinciding viral infections, massive splenomegaly, and fulminant hepatitis, the patient had a good clinical outcome, probably due to an early onset form of HLH with normal leukocyte count, normal natural killer (NK) cell function, and a lack of hemophagocytosis.

Hemophagocytic lymphohistiocytosis (HLH) triggered by Parvovirus B19 and Epstein-Barr virus co-infection is rare and unknown in infants. A 2-month-old male infant with fever, rash, bicytopenia and hepato-splenomegaly died owing to diagnostic dilemmas. Hence simply testing for hyperferritinaemia and hypertriglyceridemia/hypofibrinogenemia could diagnose HLH early while robust treatment be life-saving.

Parvovirus B19 infection can present with myriads of clinical diseases and syndromes; liver manifestations and hepatitis are examples of them. Parvovirus B19 hepatitis associated aplastic anemia and its coinfection with other hepatotropic viruses are relatively underrecognized, and there is sufficient evidence in the literature suggesting that B19 infections can cause a spectrum of liver diseases from elevation of transaminases to acute hepatitis to fulminant liver failure and even chronic hepatitis. It can also cause fatal macrophage activation syndrome and fibrosing cholestatic hepatitis...

Viruses are the leading cause of central nervous system (CNS) infections, ahead of bacteria, parasites, and fungal agents. A rapid and comprehensive virologic diagnostic testing method is needed to improve the therapeutic management of hospitalized pediatric or adult patients. In this study, we assessed the clinical performance of PCR amplification coupled with electrospray ionization-time of flight mass spectrometry analysis (PCR-MS) for the diagnosis of viral CNS infections. Three hundred twenty-seven cerebrospinal fluid (CSF) samples prospectively tested by routine PCR assays between 2004 and 2012 in two university hospital centers (Toulouse and Reims, France) were retrospectively analyzed by PCR-MS analysis using primers targeted to adenovirus, human herpesviruses 1 to 8 (HHV-1 to -8), polyomaviruses BK and JC, parvovirus B19, and enteroviruses (EV)...

BACKGROUND: Children with petechial rash are more likely to undergo invasive diagnostics, to be treated with antibiotics for potential bacterial infection and to be hospitalized. However, viruses have also been associated with petechial rash. Nonetheless, a systematic analysis of viral infections with modern available techniques as quantitative real-time polymerase chain reaction in the context of petechial rash is lacking. The purpose of this pediatric study was to prospectively uncover viral pathogens that may promote the emergence of petechiae and to analyze the correlation with the clinical characteristics and course...

Human parvovirus B19V (B19V) has been associated with various haematological disorders, but data on its prevalence in leukaemia are scarce. In this cross-sectional study, we investigated patients in Sao Paulo, Brazil with leukaemia to determine the molecular frequency of B19 variants and characterize the viral genetic variability by partial and complete sequencing of the coding of non-structural protein 1 (NS1)/viral capsid proteins 1 and 2 (VP1/VP2). The presence of B19V infections was investigated by PCR amplification of the viral NS1 gene fragment and confirmed by sequencing analysis...
