T cell Activation does not drive CD4 decline in longitudinally followed HIV-infected Elite Controllers

description | <p>Abstract</p> <p>Background</p> <p>Elite controllers (EC) are a rare subset of HIV infected individuals who control viral load below 50 copies/ml of plasma without treatment.</p> <p>Methods</p> <p>Thirty four EC were studied. The slope of CD4 count change was available for 25 of these subjects. We assessed immune activation by measuring the percent of CD38<sup>+</sup>HLA-DR<sup>+</sup>CD8<sup>+ </sup>T cells in the EC group and comparing it with that in 24 treatment-naïve HIV disease progressors and 13 HIV uninfected healthy controls.</p> <p>Results</p> <p>Compared to HIV uninfected subjects, EC had higher percentages of CD38<sup>+</sup>HLA-DR<sup>+</sup>CD8<sup>+ </sup>T cells (p < 0.001) that was lower than that observed in progressors (p < 0.01). Fifteen of 25 EC had a slope of CD4 count change that was not significantly different from 0 while 3 had a positive and 7 a negative CD4 count slope. Immune activation did not distinguish EC subsets with stable/increasing versus declining CD4 counts.</p> <p>Conclusions</p> <p>Elevated immune activation in ECs is not associated with a faster rate of CD4 decline</p> |
