Abstract

At the issue represented the etiopathogenesis of the chronic fatigue syndrome of (CFS) with immune dysfunction. Many doctors consider this problem only from the point of view of non-psychological disorders requiring only psycho-correction and non-drug treatment. However, syndromocomplex of CFS includes not only neuropsychiatric disorders, but also fibromyalgia syndrome, unexplained genesis, lymphadenopathy, non-specific polyarthralgias. It is also controversial about the feasibility of treating type 6 herpesviruses and type 7 viruses. Some authors consider the need for antiviral therapy only when reactivating the herpesvirus infection, in the transplantation of organs and tissues. However, for frequent HHV-7 and HHV-6 viremia remains resistant to ganciclovir, unlike CMV and EBV, which is successfully controlled by viremia.
