Changes in the slope of the CD4 cell count increase after initiation of potent antiretroviral treatment

J Acquir Immune Defic Syndr. 2006 Dec 1;43(4):433-5.

Abstract

Two phases of CD4+ T-cell increases are seen soon after potent antiretroviral therapy (ART) is initiated. In this 72-week analysis of 101 subjects with sustained viral suppression, we estimate the inflection point between the 2 phases to be 10 weeks after treatment initiation. Higher pretreatment HIV-1 RNA levels were associated with steeper initial CD4+ T-cell increases, likely reflecting greater redistribution of cells from lymphoid tissue to the peripheral blood compartment.
