Epstein - Barr virus Reactivation Associated with an Increased Thymidine Kinase and Normalized by an Immuno Modulatory Nano-Therapy: Three Case Reports

Abstract

Epstein-Barr Virus (EBV), a common human herpes virus known to infect most of the world population, has been mentioned in the context of many diverse human pathologies while its participation during its latency phase is more and more often demonstrated in a growing number of chronic malignancies.The biological diagnosis of the virus activity is carried out using serological parameters on the one hand, and the measurement of the viral load on the other hand. Thymidine kinase (TK) is a key enzyme in the regulation of the intranuclear thymidine pool during cell cycle progression. The rise in its plasma level therefore systematically reveals an uncontrolled cellular proliferation evoking, of course, at first a neoplastic process. Nevertheless, EBV being a DNA virus, its reactivation or even a persistent primary infection are also likely to cause an increase in the blood level of TK.Using three examples, we will show that the neutralization of EBV by an immunomodulatory nano-therapy called Bio Immune (G)ene Medicine (BI(G)MED), is accompanied by a normalization of plasma levels of TK, thus underlining the close link between the virus and this marker of cell proliferation.
