Cureus 2021 May 1;13(5):e14790. Epub 2021 May 1.

Neurology, Universidad San Francisco de Quito, Quito, ECU.

Despite the widespread Epstein-Barr virus (EBV) infections, we continue to see new reports with strange and unusual manifestations of the infection, which raises the question of how well we understand this pathogen. The age of contracting the infection is increasing in developed countries, which is changing the clinical presentation of those who get infected during their adolescence or early adulthood. In these stages, liver involvement is more prominent, and other physical symptoms are less apparent. Read More

Primary Epstein-Barr virus infection shortly after primary Cytomegalovirus infection: a case report.

J Med Case Rep 2021 May 3;15(1):257. Epub 2021 May 3.

Department of General Internal Medicine 1, Kawasaki Medical School, 2-6-1 Nakasange, Kita-ku, Okayama, 700-8505, Japan.

Background: Infectious mononucleosis (IM) and mononucleosis-like illnesses are common viral infectious diseases which are often accompanied by a high fever, pharyngitis and lymphadenopathy in adults, although such infection in childhood is generally subclinical. Most cases of IM are caused by the Epstein-Barr virus (EBV) or Cytomegalovirus (CMV). However, it is difficult to diagnose IM only with subjective symptoms, and thus EBV and CMV are nearly indistinguishable in clinical practice. Read More

To Ki or Not to Ki: Re-Evaluating the Use and Potentials of Ki-67 for T Cell Analysis.

Front Immunol 2021 9;12:653974. Epub 2021 Apr 9.

Immunosurveillance Laboratory, The Francis Crick Institute, London, United Kingdom.

This study discusses substantive advances in T cell proliferation analysis, with the aim to provoke a re-evaluation of the generally-held view that Ki-67 is a reliable proliferation marker , and to offer a more sensitive and effective method for T cell cycle analysis, with informative examples in mouse and human settings. We summarize recent experimental work from our labs showing that, by Ki-67/DNA dual staining and refined flow cytometric methods, we were able to identify T cells in the S-G/M phases of the cell-cycle in the peripheral blood (collectively termed "T Double S" for T cells in S-phase : in short "T" cells). Without our refinement, such cells may be excluded from conventional lymphocyte analyses. Read More

The Evolving Epidemiology of Nasopharyngeal Carcinoma.

Cancer Epidemiol Biomarkers Prev 2021 Jun 13;30(6):1035-1047. Epub 2021 Apr 13.

Department of Epidemiology, Harvard T.H. Chan School of Public Health, Boston, Massachusetts.

Background: The epidemiology of nasopharyngeal carcinoma (NPC) has long been a source of fascination due to the malignancy's striking geographic distribution, the involvement of the oncogenic Epstein-Barr virus (EBV), the unique association with intake of Chinese-style salt-preserved fish, and etiologic heterogeneity by histologic subtype.

Methods: This review summarizes the current epidemiologic literature on NPC, highlighting recent results from our population-based case-control study in southern China.

Results: Findings from our case-control study provide new insight into the epidemiology of NPC, including a diminished role of Chinese-style salt-preserved fish, a profound impact of EBV genetic sequence variation, modest positive associations with passive smoking and household air pollution, and possible effects of oral health and the oral microbiome.

Immunization with Epstein-Barr Virus Core Fusion Machinery Envelope Proteins Elicit High Titers of Neutralizing Activities and Protect Humanized Mice from Lethal Dose EBV Challenge.

Vaccines (Basel) 2021 Mar 19;9(3). Epub 2021 Mar 19.

The Institute for Vaccine Research, Department of Pathology, Uniformed Services University of the Health Sciences, Bethesda, MD 20814, USA.

Epstein-Barr virus (EBV) is the primary cause of infectious mononucleosis and is strongly implicated in the etiology of multiple lymphoid and epithelial cancers. EBV core fusion machinery envelope proteins gH/gL and gB coordinately mediate EBV fusion and entry into its target cells, B lymphocytes and epithelial cells, suggesting these proteins could induce antibodies that prevent EBV infection. We previously reported that the immunization of rabbits with recombinant EBV gH/gL or trimeric gB each induced markedly higher serum EBV-neutralizing titers for B lymphocytes than that of the leading EBV vaccine candidate gp350.

Hospital-diagnosed infections before age 20 and risk of a subsequent multiple sclerosis diagnosis.

Brain 2021 Mar 9. Epub 2021 Mar 9.

Clinical Epidemiology and Biostatistics, School of Medical Sciences, Örebro University, Örebro, Sweden.

The involvement of specific viral and bacterial infections as risk factors for multiple sclerosis has been studied extensively. However, whether this extends to infections in a broader sense is less clear and little is known about whether risk of a multiple sclerosis diagnosis is associated with other types and sites of infections, such as of the CNS. This study aims to assess if hospital-diagnosed infections by type and site before age 20 years are associated with risk of a subsequent multiple sclerosis diagnosis and whether this association is explained entirely by infectious mononucleosis, pneumonia, and CNS infections.
