Analytical antiretroviral therapy interruption does not irreversibly change preinterruption levels of cellular HIV.

ABSTRACT:

Objective

The impact of short-term analytical treatment interruptions (ATI) on the levels of cellular HIV and of residual activation after subsequent antiretroviral therapy (ART)-mediated plasma HIV viral load re-suppression remains under active investigation.

Design

Peripheral blood mononuclear cells (PBMC) from 23 ART-suppressed, chronically HIV-1-infected patients were evaluated at the initiation of an ATI, during ATI, and following plasma re-suppression of HIV with ART.

Methods

T-cell activation was measured by flow cytometry. Total cellular HIV DNA, and episomal 2-long terminal repeat (2-LTR) circles were measured by droplet digital PCR (ddPCR). Cellular HIV multiply spliced RNA (tat/rev), unspliced (gag), and poly(A) tailed transcripts [poly(A)] were measured by
