M. %T A Lower Baseline CD4/CD8 T-Cell Ratio Is Independently Associated with Immunodiscordant Response to Antiretroviral Therapy in HIV-Infected Subjects %D 2017 %@ 0066-4804 %U http://hdl.handle.net/10668/19000 %X We explored if baseline CD4/CD8 T-cell ratio is associated with immunodiscordant response to antiretroviral therapy in HIV-infected subjects. Comparing immunodiscordant and immunoconcordant subjects matched by pretreatment CD4 counts, we observed a lower pretreatment CD4/CD8 T-cell ratio in immunodiscordant subjects. Furthermore, pretreatment CD4/CD8 T-cell ratio, but not CD4 counts, correlated with the main immunological alterations observed in immunodiscordants, including increased regulatory T-cell (Treg) frequency and T-cell turnover-related markers. Then, in a larger cohort, only baseline CD4/CD8 T-cell ratio was independently associated with immunodiscordance, after adjusting by the viral CXCR4-tropic HIV variants. Our results suggest that the CD4/CD8 T-cell ratio could be an accurate biomarker of the subjacent immunological damage triggering immunodiscordance. %K CD4/CD8 T-cell ratio %K delayed cART %K low CD4 recovery %K T-cell turnover %K thymic function %K CD4/CD8 ratio %K antiretroviral therapy %K human immunodeficiency virus %K immunodiscordant %K Immunodeficiency-virus type-1 %K Cd4 recovery %K Tropism %K Turnover %K Events %K Switch %K Naive %K Cart %K Risk %~
