Seven patients were on HAART at the time of oral HIV-KS diagnosis and although at this time their average CD4+ T-cell count (90 cells/mm3) was lower than the average CD4+ T-cell count of the HAART-naïve patients (114 cells/mm3) (Table 3), this difference was not statistically significant. The gene discussed is CD4; the disease is Kaposi's sarcoma.
