T-cell recovery and viral suppression under HAART.

Evolution of CD4 counts (□) and plasma viral loads (▵) in the whole group of patients (A). Evolution of plasma viral loads (B) and CD4 counts (C) in virologic responders (○), transient responders (▴), and nonresponders (▪). Evolution of CD8 counts in the whole group (D). Correlation between CD8 count change and baseline CD8 count (E). Evolution of CD8 counts in patients with a baseline CD8 count less than 1000 cells/μL (○, virologic responders; ▴, transient responders; and •, nonresponders) (F). Data were expressed as the mean ± SE of each group of patients. Threshold for plasma viral load measurement by Quantiplex assay was 50 HIV RNA equivalent (Eq) copies per milliliter. For the purpose of calculation, this value was assigned when the plasma viral load became undetectable.
