Groups composed of PLWH (i.e., HIV+/CB− vs. HIV+/CB+) did not differ when considering HIV-status measures (i.e., time since diagnosis, n with detectable viral load, n with AIDS diagnosis, viral load [copies of HIV-1 RNA/mL], n with mild to moderate cognitive impairment) or immune function (i.e., CD4+ T-cell count [cells/uL], CD8+ T-cell count, CD4+/CD8+ cell ratio, total T-lymphocytes, total white blood cell count; Table 1). This evidence concerns the gene CD8A and Cognitive impairment.
