CD4 and infection: The cohort of HIV-infected progressors included recently infected untreated (RI; n = 18; median CD4 counts: 479 cells/μl; median CD8 counts: 855 cells/μl; median plasma viral load: 62,783 HIV RNA copies/ml; median time since infection: 5.7 months) (Table 2) and chronically infected under long-term (>1-year) viral-suppressive ART (CI on ART; n = 20; median CD4 counts: 558 cells/μl; median CD8 counts: 682 cells/μl; median plasma viral load: <50 HIV RNA copies/ml; median time since infection: 85 months) subjects (Table 3).
