Prognostic significance of cytotoxic T cells in individuals infected with human immunodeficiency virus.
Journal of clinical immunology(1993)
Abstract
Nine dual-fluorescence combinations were used to enumerate T-cell subsets in 112 human immunodeficiency virus type 1-infected patients. Two blood samples were analyzed, with a 6-month interval between the tests, in 53 of these 112 patients. The alteration in CD4 over this period of time correlated with the change in CD8 and CD8S6F1 (P < 0.02 and P < 0.01), irrespective of the disease stage. Two groups of patients were defined by the CD8S6F1 subset at the first normal levels. Changes in numbers of CD4, CD4CD45RA, and CD4CD29 were significantly higher in group B than in group A patients. The absolute count of CD8S6F1 could thus serve as an indicator of the ensuing depletion of the CD4 population, as well as the CD4 subsets.
