Special Issue Information

Dear Colleagues,

Epstein–Barr virus (EBV), a ubiquitous human herpesvirus, has long been implicated in a spectrum of diseases ranging from infectious mononucleosis to malignancies such as Burkitt’s lymphoma and nasopharyngeal carcinoma. While our understanding of EBV’s pathogenesis has advanced significantly, the precise mechanisms underlying its disease-associated complications remain complex and elusive.

The unprecedented global impact of the COVID-19 pandemic has ushered in a new era of viral research and epidemiological investigation. As the world grapples with the long-term consequences of this pandemic, emerging evidence suggests a potential interplay between SARS-CoV-2 and EBV, with implications for the occurrence, progression, and clinical manifestations of EBV-related diseases.

This Special Issue aims to provide a comprehensive overview of the latest research on EBV and its associated pathologies in the context of the COVID-19 pandemic. We invite contributions that delve into the following areas:

  • EBV reactivation and immune dysregulation following SARS-CoV-2 infection: Exploration of the mechanisms by which COVID-19 may trigger EBV reactivation and contribute to immune dysregulation, potentially leading to the development or exacerbation of EBV-associated diseases.
  • EBV and long COVID: Investigation of the potential role of EBV in the pathogenesis of long COVID symptoms, including fatigue, cognitive impairment, and other persistent health issues.
  • EBV-associated malignancies and COVID-19: Examination of the impact of COVID-19 on the incidence, progression, and treatment of EBV-driven cancers, such as Burkitt’s lymphoma, nasopharyngeal carcinoma, and Hodgkin lymphoma.
  • EBV and autoimmune diseases: Exploration of the relationship between EBV and autoimmune disorders in the context of COVID-19, including potential mechanisms and therapeutic implications.
  • Novel diagnostic and therapeutic strategies: Discussion of the development of innovative approaches for the diagnosis, prevention, and treatment of EBV-related diseases in the post-COVID-19 era.

By bringing together leading experts in the field, this Special Issue seeks to advance our understanding of the complex interplay between EBV and human health, providing valuable insights for future research, prevention, and clinical management.

Hsa-miR-7974 Suppresses Epstein-Barr Virus Reactivation by Directly Targeting BZLF1 and BRLF1

Epstein-Barr virus (EBV) reactivation, a key factor in Epstein-Barr virus (EBV)-associated malignancies, is regulated by specific cellular microRNAs (miRNAs). This study investigated the role of Hsa-miR-7974 (miR-7974) in this process. miRNA sequencing revealed significant downregulation of miR-7974 in reactivated EBV-positive cell lines (Raji and C666-1). Bioinformatics prediction and dual-luciferase assays confirmed the direct targeting of the EBV immediate-early gene BRLF1 by miR-7974. Furthermore, miR-7974 mimics suppressed, whereas inhibitors increased, the expression of key EBV lytic genes (BZLF1, BRLF1, and BMRF1) and the viral load, as validated by RT-qPCR. Bioinformatics analyses revealed the involvement of miR-7974 in cellular pathways such as membrane dynamics and signal transduction (MAPK, NF-κB, and IL-10), and its association with Hodgkin’s lymphoma, leukemia, and nasopharyngeal neoplasms. These findings establish that miR-7974 functions as a crucial negative regulator of EBV reactivation by directly targeting BRLF1, highlighting its potential significance in the pathogenesis of EBV-associated malignancies.

Social distancing, hand hygiene, mask wearing, surface decontamination, travel restrictions, and school closures have been implemented worldwide to control coronavirus disease 2019 (COVID-19). It was reported that the number of EBV infections as well as the age characteristics of infected persons before and after the COVID-19 pandemic significantly decreased in children from China. Since no studies have explored the changes in EBV-associated lymphomas so far, our aim was to explore EBV infection and viral-associated Hodgkin lymphoma (HL) in a pediatric cohort from a single center. A decrease in EBV+ children by serology was proved, in particular, in those undergoing primary infection, along with a significant increase in the mean age of healthy carriers. Furthermore, a decrease in EBV-associated pediatric cHL was observed post-pandemic, particularly in the NS subtype, with a marked decrease in cases diagnosed from 2022 onward. Even though the underlying reasons for the change in incidence rates seen in this study still remain speculative, it could be hypothesized that, after the pandemic, older children have a better ability to control the EBV-mediated lymphomagenesis, based on the fact that the age of infected patients increased.

Introduction: The concomitant use of antibiotics, especially beta lactams, during acute EBV infection is widely associated with an increased risk of skin manifestations; the actual pathophysiology and prevalence of this phenomenon are still debated. Case report: We present the first reported case of atypical exanthema associated with amoxicillin intake in a patient with EBV-related nasopharyngeal carcinoma. We recorded a pattern in the plasma EBV-DNA load consisting of a significant increase at the onset of the rash with a sudden remission after its resolution. The patient recovered without sequelae. Discussion/Conclusions: The temporal relationship and the reported data on rash morphology, clinical findings and triggering factors support a possible correlation between the intake of beta-lactam antibiotics, particularly amoxicillin, and the onset of cutaneous manifestations in a patient with nasopharyngeal carcinoma. Such reactions can be a challenging differential diagnosis and may warrant increased provider consideration when choosing to prescribe beta lactams in patients affected by nasopharyngeal cancer.
