Viral load and burden modification following early antiretroviral therapy of primary HIV-1 infection

Abstract

The parameters of viral replication and CD4 cell recovery were only slightly better in the patients receiving ZDV monotherapy than in the untreated patients, thus confirming that the course of the infection is hardly affected by the monotherapy. The early introduction of HAART greatly reduces plasma viraemia and restores the number of CD4 cells for up to 1 year. HIV-DNA remains detectable, although at low levels, thus confirming that the early established reservoir of infected cells is little affected. Longer periods of observation and the introduction of complementary approaches, such as immunomodulatory therapies, will provide further information concerning the possibility of radically interfering with the natural evolution of the disease.
