Abstract
Epstein – Barr virus, related to herpes viruses, causes infectious mononucleosis during the initial infection; after recovery, the virus persists in the body throughout lifetime. The presence of clinical symptoms and viral load in a patient in 6 months after the infectious mononucleosis disease indicates the formation of chronic active Epstein – Barr viral infection. Hemophagocytic lymphohistiocytosis, posttransplantation lymphoproliferative disease and chronic fatigue syndrome, which has a polyetiological nature, are also associated with the activation of the persistent Epstein – Barr virus. Most of these diseases develop in children due to their physiological immunodeficiency and are accompanied by high mortality – up to 50%. Immune mechanisms, in addition to the virus itself, play a leading role in the pathogenesis of the diseases. The article summarizes all existing approaches to the treatment of chronic Epstein – Barr virus-associated diseases. The authors have analyzed the effectiveness of these approaches on the basis of various published studies. These diseases are treated with etiotropic antiviral drugs – nucleoside analogs, nonspecific immunotherapy, targeted therapy with monoclonal antibody preparations, immune cellular CD8+ therapy. In case of ineffectiveness of these methods, the alternative bone marrow transplantation is used. The article highlightes promising areas for the development of new approaches to the treatment of Epstein – Barr virus-associated diseases.
