Predictive Value Of The Expression Of Cd38 And Of Hla-Dr On T Cells In Hiv Infection - A Preliminary Report
SEVENTH EUROPEAN CONFERENCE ON CLINICAL ASPECTS AND TREATMENT OF HIV-INFECTION(1999)
摘要
To assess the clinical value of the expression of CD38 and of HLA-DR on T cells the subpopulations CD4/CD8(bright)/HLA-DR and CD4/CD8(bright)/CD38 were studied in 848 HIV+ patients at different stages of disease, 397 observed sequentially. The fraction of CD38+ and of HLA-DR+ T cells and its mean fluorescence intensity (MFI) showed globally a significant correlation with well known markers of disease: clinical stage, CD4 number and viral load. In agreement with these correlations, increased baseline values of the fraction of CD38+ cells or of its MFI in CD8 and CD4 cells, and of the fraction of HLA-DR+ cells or of its MFI in CD4 (but not in CD8) cells, are all very significantly associated with a faster disease progression, what confirms their prognostic value. In adition to previous reports, we show that both the fraction CD38+ CD8 and its MFI and, as well, the expression of CD38 on CD4 have prognostic value.
