During this phase of infection patients exhibited a growth of the median value of virus load in cases of both rise as decline in CD4 cell count during long observation period. In addition, towards the end of the observation period, the percentage of patients with virus load 3.3 lg copies/ml considerably expanded. 43% correlation between CD4 cell count and duration of the HIV-infection was detected during the fourth infection phase in persons that did not receive antiretroviral treatment. Most of the patients in the third and the fourth infection phases had essential CD4 cell count growth during antiretroviral treatment. Best values were observed in patients with the initial value of CD4 400 cells/pl belonging to the third HIV-infection phase.</span>HIV- infectionCD4 T-lymphocytesviral loadantiretroviral treatmentВИЧ инфекцияCD4 T-лимфоцитывирусная нагрузкаантиретровирусная терапия[1.
