Because immune subset measurement is often performed in HIV-positive individuals, we examined whether these were predictive of mortality independently of the prognostic index, or could predict time to progression of KS. <\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and Methods<\/jats:title><jats:p> We performed univariate and multivariate Cox regression analyses on a data set of 326 individuals with AIDS-associated KS to identify immune subset covariates predictive of overall survival and time to progression. Adaptive (CD8 T cell and CD19 B cell) and innate (CD16\/56 natural-killer cell) immune parameters were studied by flow cytometry. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> In univariate analyses, all three immune subsets had significant effects on overall survival (P &lt; .025). In multivariate analyses including the prognostic index, only CD8 counts remained significant (P = .026), although its effect on the overall prognostic index is small. An increase of 100 cells\/mm<jats:sup>3<\/jats:sup> in the CD8 count confers a 5% improvement in overall survival. Individuals with a higher CD8 count did not have an increased time to progression. Patients who were already on HAART at the time of KS diagnosis did not have a shorter time to progression than those who were antiretroviral na\u00efve at KS diagnosis. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> The CD8 count appears to provide independent prognostic information in individuals with AIDS-associated KS.
