To monitor multiple Epstein-Barr virus (EBV) infections during the early and convalescent stages of infectious mononucleosis (IM), a cloning and sequencing study of the LMP1 gene was conducted in saliva and peripheral blood mononuclear cells (PBMCs) from 23 patients with IM at day 0 (D0) and day 180 (D180) after the onset of the disease. Multiple EBV strains were detected in 9 (39%) of the patients during follow-up, with 7 of 9 cases detected as early as D0. Six of the nine patients harbored the same dominant strain in saliva and PBMCs during follow-up, with a trend toward a restriction of the number of EBV strains in saliva but not in PBMCs at D180. Furthermore, transmission of a minor strain was observed between partners in a heterosexual couple. There was no correlation between multiple infections and EBV DNA load in either compartment.

Encephalitis due to Epstein-Barr Virus (EBV) is a rare condition that primarily affects children and immunosuppressed patients. Diagnosing EBV encephalitis can be challenging due to its nonspecific clinical presentation and the lack of confirmatory tests. We present the case of a 66-year-old woman with a history of kidney transplantation who was admitted due to progressive subacute mental deterioration, preceded by vertigo and without fever.

Although the majority of patients with nasopharyngeal carcinoma (NPC) present with early-stage or locoregional disease that can be treated with definitive radiotherapy, approximately 20% of patients experience disease recurrence, and 15% present with metastatic disease that is not amenable to curative therapy. Management of patients with recurrent or metastatic (r/m) NPC who are not candidates for local salvage therapy is challenging in Canada, as there is uncertainty in extrapolating evidence that is largely generated from Southeast China to non-endemic regions such as Canada. Currently, treatment options in Canada are limited to chemotherapy regimens that can only achieve short-term response and prolongation of survival.

Background: There is no consensus regarding the optimal regimen for metastatic nasopharyngeal carcinoma (dmNPC). Locoregional intensity modulated radiotherapy (LRRT) following palliative chemotherapy (PCT) has been shown to prolong the overall survival (OS) and improve the progression-free survival (PFS) of patients with dmNPC, compared with PCT alone. However, patients with a high tumor burden do not benefit from additional LRRT, which inevitably results in toxicity.

While bone, liver, and lung metastases are well-documented, central nervous system (CNS) involvement, particularly spinal and meningeal metastases, is extremely rare. We present a 41-year-old male with nasal obstruction and diplopia, diagnosed with locally advanced NPC.

The increasing prevalence of neurodegenerative diseases is a formidable task due to their multifactorial causation and treatments limited to disease maintenance and progression. Epstein-Barr virus (EBV) is reported to be involved with neuropathologies; previous studies from our group suggested the effective binding of epigallocatechin-3-gallate (EGCG) with EBV nuclear antigen 1 (EBNA1) and glycoprotein H (gH). Therefore, in the current study, we evaluated the anti-EBV effect of ECGG on the neuronal cells.
