Hemophagocytic lymphohistiocytosis (HLH) is a rare, potentially lethal condition due to dysfunctional immune response causing severe inflammatory syndrome. Epstein-Barr virus (EBV) – induced HLH form of secondary HLH, very serious presentation an otherwise benign viral infection. Here we present case 31 year old previously healthy male with prolonged fever and constitutional symptoms, eventuall...
Herpesviruses are main sculptors of natural killer (NK) cell repertoires. While the ?-herpesvirus human cytomegalovirus (CMV) drives accumulation adaptive NKG2C-positive NK cells, ?-herpesvirus Epstein–Barr virus (EBV) expands early differentiated NKG2A-positive cells. cells support immunity by antibody-dependent cellular cytotoxicity, seem to preferentially target lytic EBV replicating B The i...
Acute infectious interstitial pneumonitis (IP) (Epstein Barr virus (EBV)-associated IP) in children has been most commonly associated with human immunodeficiency (HIV) infection and immunocompromised hosts. Here we report a case of EBV-associated cervical lymphadenopathy an immunocompetent child. Patient underwent extensive routine serologic workup which revealed positive polymerase chain react...
Epstein-Barr virus (EBV) infection is a benign disease, which may occasionally be fatal, particularly in children and immunocompromised patients. Epstein-Barr virus infection is rare in elderly subjects and seems to have a self-limited course. A case of fatal liver failure due to chronic active EBV infection in a 75-year-old man is described. The etiology was established postmortem by cellular ...
The Epstein-Barr virus (EBV) infection is an endemic disease, over 90% of the population being exposed to it by adulthood. EBV is implicated in the etiology of a significant number of neoplasms, which acquire particular features in terms of course and prognosis. Incidence rates are much higher in children. To establish the link between EBV and neoplasms, EBER (Epstein-Barr virus non-encoded RNA...
Background: Immunophenotyping in the rare group of nodal Peripheral T-cell Lymphomas (PTCL) exposes interesting features such as T-cell marker downregulation and paradoxically, the presence of reactive, clustered large-sized CD20 positive B-cells (B-cell proliferation). Epstein-Barr virus (EBV) has been suggested as a putative etiology in pathogenesis of B-cell lymphoma. We aimed to review the ...
INTRODUCTION: Epstein-Barr virus (EBV) and cytomegalovirus (CMV) are herpesviruses, which account for the majority of oral viral infections. Herpes simplex virus, varicellazoster virus, and Epstein-Barr virus infections nearly always result from reactivation of latent virus, while cytomegalovirus infections, besides presenting as reactivated disease, are almost as likely to present as a primary...
epstein barr virus (ebv) is one of seven known herpes virus pathogenic for humans.since it is ubiquitous, it infects nearly 95% of individuals worldwide by adulthood .ebv is the etiologic agent of infectious mononucleosis(im)and is implicated in burkitt lymphoma,nasopharyngeal carcinoma and x-linked lymphoproliferative syndrome.diagnosis of im based upon clinical manifesta¬tions in conjunction ...
As the first discovered human cancer virus, Epstein-Barr virus (EBV) causes Burkitt's lymphoma and nasopharyngeal carcinoma. Isolating virions for determining high-resolution structures has been hindered by latency—a hallmark of EBV infection—and atomic are thus available only recombinantly expressed proteins. in present study, symmetry relaxation subparticle reconstruction, we have determined ...
The aim of this study was to analyze proliferative verrucous leukoplakia (PVL) and oral squamous cell carcinoma (OSCC) for the possible presence of Epstein-Barr virus (EBV). We studied three groups: Sub-Group 1 was composed of 10 patients with PVL, (6 of whom had developed OSCC); Sub-Group 2 comprised 5 patients with OSCC but no preceding PVL; and Sub-Group 3 were 5 controls with clinically nor...
