Factors associated with the evolution of the viral load in individuals with HIV infection.
The temporal evolution of the viral load (VL) in a group of patients under clinical care and the identification of individual variables that determined this evolution was studied using a retrospective descriptive study of the VL determinations on 1336 patients between September 1996 and June 2000. During follow-up, patients' VLs increasingly fell below the detection threshold. Those patients who had received antiretroviral treatment prior to the monitoring of the viraemia presented lower VLs at the start of their follow-up. Those patients who had been cared for on the same unit throughout their follow-up maintained lower VLs. Female patients uniformly presented lower VL results than the males. The immunological status at the beginning of follow-up and the basal VL determined the initial evolution of the patients' VL, although it did not do so in the final stages of follow-up. The immunological and virological state at the onset of the follow-up determines the evolution of the patients' VL.
