EBV can indeed come back, particularly in individuals with weakened immune systems or those undergoing treatments that suppress the immune response. Monitoring and managing EBV reactivation is crucial in these populations to prevent associated complications and diseases.
Epstein-Barr Virus (EBV) is a common virus that can cause infectious mononucleosis and is associated with various lymphoproliferative diseases. Once infected, the virus remains in the body for life, residing in a latent state within certain cells. This article explores whether EBV can reactivate and the conditions under which this might occur.
EBV Reactivation in Immunocompromised Individuals
EBV reactivation is particularly significant in individuals with compromised immune systems, such as renal transplant recipients. A study involving 41 renal transplant recipients found that EBV excretion occurred more frequently in those who received cadaver kidneys and antithymocyte globulin, a medication used to prevent organ rejection. The study concluded that increased immunosuppression augments the rate of EBV reactivation, suggesting that EBV can indeed come back under certain conditions1.
EBV and Nasopharyngeal Cancer
In patients with nasopharyngeal cancer (NPC), EBV DNA levels in plasma can serve as a biomarker for residual disease. A randomized controlled trial involving 789 patients with NPC found that detectable levels of EBV DNA post-radiotherapy were associated with a higher risk of relapse. This indicates that EBV can persist and potentially reactivate, contributing to disease recurrence2.
Suppression of EBV Replication
Valganciclovir, an antiviral medication, has been studied for its effects on EBV replication. In a double-blind, placebo-controlled study, valganciclovir significantly reduced the proportion of days with detectable EBV and the quantity of the virus. This suggests that while EBV can reactivate, its replication can be suppressed with appropriate antiviral treatment3.
